2. Description of the Related Art A living tissue is irradiated with energy such as laser light, microwaves, radio waves, and ultrasonic waves, and the living tissue is extinguished by heating, degeneration, necrosis, coagulation, cauterization, or evaporation. Treatment devices for treating tissue are known. This treatment device is generally configured to include an energy generator for generating energy, and an energy transmission irradiation unit for transmitting the generated energy to guide it to living tissue and irradiate it.

The energy transmission irradiation section has a shorter life than the energy generator, and is discarded or replaced after being used once or several times.

In the above-described treatment apparatus, the energy transmission efficiency varies depending on the individual energy transmission irradiation unit that is frequently replaced. In this case, even if the amount of energy generated by the energy generator is constant, the energy applied to the living body differs depending on the combined energy transmission irradiation unit, and the heating performance for treatment is not stable.

Controls the laser light source device 3 so that the energy transmission irradiation unit 1 outputs a desired amount of energy.

The laser light source device 3 is connected to the control main body 2 via a communication cable 39, and emits laser light based on the information transmitted from the control main body 2.

The rectal probe 4 is inserted from the anus into the rectum, detects the temperature of the rectal wall on the side where the prostate is located, and transmits the detected temperature to the control body 2 via the sensor signal lead 41. The foot switch 5 outputs a signal that prompts the control body 2 to irradiate a laser beam when stepped on by the operator.

The display / input unit 6 displays predetermined information to the user and receives predetermined settings and operations. For the display / input unit 6, a touch panel system or a system for inputting from an input device such as a keyboard and a mouse (not shown) can be adopted.

Next, the configuration according to the present invention will be specifically described.

First, the energy transmission irradiation unit 1 will be described with reference to FIGS. 1 and 2. FIG. 2 is an enlarged view of the energy transmission irradiation unit 1.

The energy transmission irradiation unit 1 is the urethral insertion unit 1
1, a laser transmission unit 12, a urethral signal cable 13, a water supply tube 14, and a drainage tube 15. The laser transmission unit 12, the urethral signal cable 13, the water supply tube 14, and the drainage tube 15 each extend from the energy transmission irradiation unit 1.

The urethral-insertion section 11 is formed in a long shape, is inserted into the urethra, and irradiates a living tissue with laser light. The laser transmission unit 12 is formed of an energy transmission member such as an optical fiber, and has an optical fiber connector 12
It is connected to the laser light source device 3 by 2. Then, the laser transmission unit 12 transmits the laser light generated by the laser light source device 3 to the urethral-insertion unit 11.

As shown in FIG. 2, the laser beam transmitted from the laser transmission section 12 is the tip 121 of the urethral-insertion section 11.
Laser reflecting surface 16 that is guided to the laser and reflects the laser light
Is output toward and is reflected. Urethral insertion part 1
In No. 1, a window portion 111 is opened on the side surface near the tip portion and is covered with a laser-transparent cover member (not shown). The laser light reflected by the laser reflection surface 16 is output from the window portion 111 toward the side surface. In addition,
The laser reflecting surface 16 is arranged at a position facing the front of the distal end portion 121, and while changing the angle, the urethral-insertion portion 11 is formed.
By reciprocating along the longitudinal direction of the laser beam, it is possible to irradiate the laser beam in a concentrated manner on one part of the biological tissue.

The urethral signal cable 13 transmits information on the temperature detected by the two temperature sensors 112 and 113 provided in the window 111 to the control body 2. Temperature sensor 112
Is arranged at a position where the laser light does not hit, and the temperature sensor 113 is arranged at a position where a part of the laser light hits.

Water supply tube 14 and drainage tube 15
Is connected to a cooling circulation unit (not shown) arranged inside the cooling unit door 29 of the control body 2. Then, the cooling medium included in the cooling circulation unit is guided to the energy transmission irradiation unit 1 via the water supply tube 14 and returned to the cooling circulation unit via the drainage tube 15.
The cooling medium guided to the energy transmission irradiation unit 1 passes through the circulation path formed in the urethral-insertion unit 11 and passes through the laser reflection surface 16
And the living tissue is further cooled through the window portion 111 of the urethral-insertion portion 11.

The energy transmission irradiation unit 1 described above is
It has a shorter life than an energy generator, and is discarded or replaced after being used once or several times. When the energy transmission irradiation unit 1 is replaced, the energy transmission irradiation unit 1 is replaced including the optical fiber from the optical fiber connector 122 to the urethral-insertion unit 11. Therefore, with the optical fiber,
Due to the connection between the optical fiber connector 122 and the laser light source device 3, the transmission efficiency of the laser light varies each time it is replaced.

In the energy transmission irradiation unit 1 according to the present invention, the transmission efficiency of the laser beam is obtained in advance at the manufacturing stage, and a product individual identification symbol including the measured transmission efficiency is given. The product identification code is, for example,
It is directly attached to the packaging of the energy transmission irradiation unit 1 (not shown) or a part of the energy transmission irradiation unit 1.

The product individual identification code is, for example, a code of product individual information, laser light transmission efficiency information, and a checksum. Specifically, when the product individual manufacturing number is “012345” and the obtained laser light transmission efficiency is 75%, the product individual identification code has “012345” as the upper six digits as the product individual information. Including the information of the transmission efficiency of laser light, "0" is added to the next 3 digits.
75 "is included. Furthermore, the product individual identification code is "012
The number of 1's digit when the respective digits of "345" and "075" are summed up is included as a checksum. Where 0 + 1 + 2 + 3
Since + 4 + 5 + 0 + 7 + 5 = 27, the checksum is “7”, which is the ones place of 27.

Therefore, in the above example, the product individual identification code is a 10-digit number "0123450757". By including the checksum in the product individual identification code, even if the product individual identification code is erroneously input, the erroneous input will not be made due to the difference between the last digit of the total number other than the checksum and the checksum. Can be found.

Here, the transmission efficiency of the laser light is not only the laser light transmittance of the optical fiber of the laser transmission section 12 of the energy transmission irradiation section 1, but also the optical fiber connector 122.
Which causes attenuation of the laser light, such as optical connection loss in the laser light, the reflectance on the laser reflecting surface 16, the laser light transmittance of a laser-transparent cover member (not shown) that covers the window 111 of the urethral-insertion portion 11. The element of is added.

Next, with reference to FIG. 3, the specific configurations of the control body 2 and the laser light source device 3 will be described. Figure 3
3 is a block diagram showing the configurations of a control body 2 and a laser light source device 3. FIG.

The control main body 2 has a display / input unit 6, a temperature measuring unit 21, a cooling water adjusting unit 22, a memory 23, and a control unit 24.

The display / input unit 6 is a user interface and allows the user to input various settings. The user uses the energy transmission irradiation unit 1 on the display / input unit 6.
It is possible to set the energy value of the laser beam (hereinafter referred to as irradiation energy value) desired to be output from, and further input the product individual identification symbol given to the energy transmission irradiation unit 1 described above.

The temperature measuring unit 21 is connected to the energy transmission irradiation unit 1 and the rectal probe 4 outside the control body 2, and the temperature of the urethra detected by the energy transmission irradiation unit 1 and the rectal probe 4 are detected. The rectal temperature is entered. The temperature measuring unit 21 monitors the input temperature,
Output to the control unit 24. Therefore, the control unit 24, based on the temperature of the biological tissue monitored by the temperature measuring unit 21, either the laser light source device 3 or the cooling water adjusting unit 22,
Alternatively, both can be controlled to prevent excessive heating of normal tissue.

The cooling water adjusting unit 22 is connected to the energy transmission irradiation unit 1 by the water supply tube 14 and the drainage tube 15. The cooling water adjusting unit 22 is controlled by the control unit 24 and adjusts the flow rate and temperature of the cooling water flowing to the energy transmission irradiation unit 1. The control unit 24 may control the cooling water adjustment unit 22 based on the temperature of the urethra monitored by the temperature measurement unit 21.

The memory 23 stores predetermined programs and data. The memory 23 includes, for example, a control program for controlling the laser light source device 3 and a predetermined temperature serving as a reference for determining whether the temperature of the living tissue detected by the energy transmission irradiation unit 1 is abnormally heated. Is memorized. Further, the memory 23 stores and stores the product individual identification symbol input by the display / input unit 6 as a history.

The control unit 24 controls the laser light source device 3 so that the laser beam having the irradiation energy value set by the user from the display / input unit 6 is irradiated by the energy transmission irradiation unit 1, and the rectal probe 4 is controlled. Temperature sensor provided in the urethra insertion part 11
The laser light source device 3 and the cooling water adjusting unit 22 are controlled based on the detection result of 13. The control unit 24 is connected to the foot switch 5 and controls the laser light source device 3 only while the foot switch is stepped on by the user. The control unit 24 determines the suitability of the product individual identification symbol input in the display / input unit 6.

When it is determined that the product individual identification symbol is appropriate, the decoding unit 241 included in the control unit 24 decodes the laser light transmission efficiency of the energy transmission irradiation unit 1 from the product individual identification symbol. The control unit 24 determines whether or not the transmission efficiency of the decoded laser light is appropriate, and if appropriate, stores the product individual identification symbol and the information of the transmission efficiency of the laser light decoded by the decoding unit 241 in the memory 23.

If the product individual identification code is not appropriate, or if the transmission efficiency of the decoded laser light is not appropriate, the control unit 24 displays on the display / input unit 6 that there is an error and re-input is necessary. Let

The control unit 24 sends the laser light irradiation energy value set by the display / input unit 6 and the transmission efficiency of the laser light stored in the memory 23 to the laser light source device 3.

The laser light source device 3 includes an arithmetic unit 31, a memory 32, a laser output adjusting unit 33, and a laser oscillator 34.
Have and.

The arithmetic unit 31 controls the laser output adjusting unit 33 to adjust the laser light irradiation energy value transmitted from the control unit 24 of the control body 2 and the laser light transmission efficiency of the energy transmission irradiation unit 1. The energy generation value of the laser light generated by the laser oscillator 34 is calculated.

Specifically, the arithmetic unit 31 first refers to the transmission efficiency of the laser light of the energy transmission irradiation unit 1, and the energy amount of the laser light actually output from the energy transmission irradiation unit 1 is determined by the laser oscillator 34. It is examined how much the laser light oscillated in 1 is attenuated as compared with the amount of energy. Then, the attenuation in the energy transmission irradiation unit 1 is taken into consideration so that the energy amount of the laser light actually output from the energy transmission irradiation unit 1 becomes the same as the irradiation energy value set by the user in the display / input unit 6. The energy generation value of the laser light by the laser oscillator 34 is calculated.

For example, when the energy amount of the laser light set by the display / input unit 6 is P (W) and the transmission efficiency of the laser light of the energy transmission irradiation unit 1 is T, P '= P.
/ T is calculated, and the laser output control unit 33 causes the laser oscillator 34 to output laser light having an energy amount of P ′ (W).

Then, the calculation section 31 outputs the energy generation value of the laser beam which is the calculation result to the laser output control section 33 to the laser output control section 33.

The memory 32 stores a calculation program for the calculation unit 31 to perform the above-described calculation.

The laser output adjusting section 33 adjusts the output of the laser beam by the laser oscillator 34 based on the energy generation value of the laser beam output from the calculating section 31. The laser oscillator 34 is adjusted by the laser output adjusting unit 33 and outputs laser light to the laser transmitting unit 12.

As described above, in the energy irradiation device, the laser beam is attenuated in the energy transmission irradiation unit 1, that is,
Based on the transmission efficiency of the laser light, the energy generation value amplified in advance is calculated, and the laser oscillator 34 oscillates the laser light. Therefore, the oscillated laser light is attenuated via the optical fiber connector 122, the optical fiber, the laser reflection surface 16, and the cover member of the energy transmission irradiation unit 1, and the energy set by the user at the display / input unit 6 is set. In doses to the urethra.

Next, the process of the product individual identification symbol by the control unit 24 of the control body 2 will be specifically described.

FIG. 4 is a flow chart showing the operation of the control section 24 of the control body 2.

In the description of FIG. 4, the product individual identification symbol input in the display / input unit 6 is "012345075".
7 ”.

When the product individual identification symbol is input to the display / input unit 6, the input product individual identification symbol is immediately sent to the control unit 24 (step S401).

First, the control unit 24 pays attention to the last digit of the product individual identification code "0123450757", that is, 7, which is the checksum, and determines whether this checksum is appropriate (step S402). ). Specifically, the control unit 24 sums up the numbers of the respective digits of the number "012345075" other than the lowermost one digit (checksum) of the product individual identification symbol, and confirms that the lowermost one digit and the checksum are the same. Determine whether If they are the same (step S40)
2: YES), the process proceeds to step S404, and if they are not the same (step S402: NO), the product individual identification symbol has been erroneously input, so an error and a re-input prompt are displayed on the display / input unit 6. (Step S4
03).

Here, the total of "012345075" is 27 and the last digit of 27 is "7", which is equal to "7" of the checksum. Therefore, the control unit 24
Can confirm that there is no erroneous input in the input product individual identification symbol (step S402: YES).

Next, the control unit 24 adds the new entry input to the display / input unit 6 this time in the history of the product individual identification symbols input in the display / input unit 6 in the past and stored in the memory 23. Product individual identification code "012345075
7 ”is present (step S40)
4).

When a new product individual identification code "0123450757" exists in the history stored in the memory 23 (step S404: NO), the product having the same product individual identification code, that is, the same product has been used in the past. Since it can be determined that the same product has been used and the reuse of the same product is not hygienic, the control unit 24 causes the display / input unit 6 to display an error message, prompts the connection of the new energy transmission irradiation unit 1, and a new product. Prompt for individual identification code (step S40)
3).

When the product individual identification symbol "0123450757" does not exist in the history stored in the memory 23 (step S404: YES), the decoding unit 241.
Reads (extracts) the transmission efficiency of the laser light of the energy transmission irradiation unit 1 from the product individual identification symbol (step S40).
5). Here, the decoding unit 241 decodes that the laser light transmission efficiency of the energy transmission irradiation unit 1 is 75% by referring to the last four digits to the last two digits "075" of the product individual identification symbol. .

Next, the control section 24 determines whether or not the transmission efficiency of the laser beam decoded by the decoding section 241 is 0.6 or more and 0.8 or less (step S406). When the transmission efficiency of the decrypted laser light is not 0.6 or more and 0.8 or less (step S406: NO), the decrypted transmission efficiency is an impossible value for the product, so there is an error in the input of the product identification code. Therefore, the control unit 24 displays
An error and a display prompting re-input are displayed on the input unit 6 (step S403).

On the other hand, the transmission efficiency of the decoded laser light is 0.
If 6 or more and 0.8 or less (step S406: YE
S), since it can be determined that there is no error in the input product individual identification symbol, the control unit 24 determines that this product individual identification symbol
The decrypted transmission efficiency is stored in the memory 23 (step S407). Here, the stored product individual identification symbol is used for history collation from the next time onward.

As described above, the energy irradiating apparatus according to the present invention constantly produces a laser beam having the irradiation energy value set by the user by a simple input operation regardless of the individual difference of the energy transmitting and irradiating section 1. Since the tissue can be irradiated, the therapeutic effect can be stabilized.

Further, the energy irradiation device according to the present invention is
The history of the product individual identification symbols input in the past is collated, and when the same energy transmission irradiation unit 1 is used in the past, the laser light is not emitted, so the energy transmission irradiation unit 1 which is a disposable product is re-generated. It can be prevented from being used.

Further, in the energy irradiating device according to the present invention, since the laser light source device 3 has the arithmetic unit 31, it is possible to adjust the energy amount of the lasing laser beam even when only the laser light source device 3 is used. It will be possible.

In the above description, the product individual identification symbol is manually input in the display / input unit 6, but instead of this, the numbers may be automatically read by the scanner and the character reader. Good.

Further, although the product individual identification symbol is represented by a 10-digit number in the above description, it is not limited to this. For example, the product individual identification code may be represented by an identification code such as a barcode or a two-dimensional barcode. In this case, the display / input unit 6 is provided with an identification code reader such as a bar code reader, and the identification code can be read by the bar code reader to obtain the product individual identification symbol. By using the bar code reader, it is possible to prevent input errors due to manual input.

(Second Embodiment) In the second embodiment, not the laser light source device 3, but the control main body 2 is provided with an arithmetic unit for calculating the energy amount of the laser light output to the laser light source device 3. This is different from the first embodiment in that it is provided. Therefore, since the second embodiment has almost the same basic configuration as that of the first embodiment, the same components are designated by the same reference numerals as those in FIG. 3, and the description thereof will be omitted. Below, the control part 25 of the control main body 2 is demonstrated.

FIG. 5 is a block diagram showing the configurations of the control main body 2 and the laser light source device 3 in the second embodiment.

The control body 2 has a control section 25. The control unit 25 includes a decoding unit 251 and an arithmetic unit 25.
2 and are included.

When the user inputs the product individual identification symbol of the energy transmission irradiation unit 1 from the display / input unit 6,
The control unit 25 determines whether or not the input of the product individual identification symbol is correct based on the checksum of the product individual identification symbol.
When determining that the input is correct, the control unit 25 compares the input product individual identification symbol with the history of the product individual identification symbol stored in the memory 23.

When the same product individual identification symbol does not exist in the history, the decoding unit 251 of the control unit 25 decodes the product individual identification symbol and extracts the laser light transmission efficiency of the energy transmission irradiation unit 1.

Further, the control section 25 judges whether the transmission efficiency of the extracted laser light is within a predetermined range, and if it is within the predetermined range, the product individual identification symbol and the transmission efficiency of the laser light are stored in the memory 23.

Further, the calculation unit 252 inputs the irradiation energy value of the laser beam set by the display / input unit 6 to the calculation unit 252 together with the product individual identification symbol.

The calculation unit 252 calculates the energy generation value of the laser light generated in the laser light source device 3 based on the input transmission efficiency of the laser light and the irradiation energy value of the laser light. The calculation here is the same as that of the first embodiment.

The control section 25 transmits the energy generation value calculated by the calculation section 252 to the laser output adjusting section 33 of the laser light source device 3.

As shown in FIG. 5, the control main body 2 and the laser light source device 3 are separate bodies, each of which is provided with a housing constituting a different outer frame. Furthermore, the control unit 25 of the control body 2
Since the calculation unit 252 is provided in the laser light source device 3, the laser light source device 3 can be used not only for exclusive use but for general purpose.
Therefore, if the signal specifications are within the same range, different laser light source devices can be used in combination with the control body 2 as appropriate.

For example, it is possible to prepare a plurality of laser light source devices having different rated output values of laser light and use them while exchanging them appropriately. By doing this, the system performance of the heat treatment apparatus as a whole is improved,
Further, since the laser light source device 3 can be easily replaced, the maintainability is improved.

(Third Embodiment) In the first and second embodiments, the product individual identification symbol is input through the display / input unit 6, and the laser of the energy transmission irradiation unit 1 is output from this product individual identification symbol. The light transmission efficiency was extracted. But the third
In the embodiment, the energy transmission irradiation unit 60 is provided with a resistor, and the transmission efficiency of the laser light is extracted from the resistance value of the resistor.

The basic structure of the third embodiment is almost the same as that of the first and second embodiments. Therefore, the same components are designated by the same reference numerals as those in FIG. 3 and their explanations are omitted. To do. Below, the energy transmission irradiation part 60 is demonstrated.

FIG. 6 is an enlarged view of the energy transmission irradiation unit 60 according to the third embodiment.

The energy transmission irradiation unit 60 in the third embodiment has a resistor 61 inside. This resistor 6
1 has a resistance value corresponding to the conduction efficiency of the laser beam of the energy transmission irradiation unit 60 which is measured in advance in the manufacturing stage. For example, when the conduction efficiency of the laser beam of the energy transmission irradiation unit 60 is 80%, the energy transmission irradiation unit 6
The resistance value of the resistor 61 incorporated in 0 is determined such that the resistance value of the resistor 61 is 80 kΩ.

A lead wire is connected to the resistor 61, passes through the urethral signal cable 13, and is connected to the control body 2.

Here, the control main body 2 automatically detects the resistance value of the resistor 61 via the lead wire, and determines the transmission efficiency of the laser light of the energy transmission irradiation unit 60 connected to the laser light source device 3. To do.

As described above, in the third embodiment, it is possible to save the trouble of inputting the product individual identification symbol to the display / input unit 6 and to prevent the input error.

In the first to third embodiments, the energy transmission irradiation units 1 and 60 have been described as including the urethral-insertion unit 11 used for the treatment of benign prostatic hyperplasia, but the present invention is not limited to this. The energy transmission irradiation unit 1 or 60 may be various treatment instruments that are inserted into a body cavity or a blood vessel to apply energy to the body cavity or the blood vessel. The state of the target portion may be observed by adopting a configuration in which the endoscope is inserted inside the energy transmission irradiation unit 1 or 60.

Further, in the first to third embodiments, the energy transmission irradiation unit 1 or 60 is replaced only once, but the present invention is not limited to this. Of the energy transmission irradiation units 1 or 60, it is the urethral-insertion unit 11 that is actually inserted into the body, so only this housing may be replaced. When only the housing is replaced, by inputting the product identification code given to the housing to the control body 2, the reuse of the housing can be detected and the reuse can be prevented as described above. If only the housing is replaced, the cost can be reduced while maintaining the hygienic level.
