Description

Cerebral hemorrhage mirror with adjustable and fixed suction structure

Technical Field

The invention relates to the technical field of medical appliances, in particular to a cerebral hemorrhage mirror with an adjustable and fixed suction structure.

Background

Hypertension cerebral hemorrhage (HICH) is a frequently occurring disease of neurosurgery, and has high disability rate and death rate. HICH accounts for 43.0% -51.0% of cerebrovascular disease, mainly concentrated in people over 55 years old, but in recent years there is a trend towards younger. The HICH disease progresses rapidly, and if the hematoma exceeds 20.0mL, the disability rate can reach 30.0%. Surgical treatment of HICH, i.e., surgical removal of an intracerebral hematoma, can increase survival chances, thereby improving prognosis and improving patient quality of life.

Currently, there are three major surgical treatments for cerebral hemorrhage: firstly, the operation time is long, the blood loss is more, the wound is large, the postoperative edema is heavy, and the prognosis of the patient is affected. Secondly, the operation time is short, the incision is small, the brain injury is small, hematoma can be completely removed under the direct vision state, the responsible blood vessel can be found to be timely and perfect to stop bleeding, the pressure is fully reduced, and the operation is simple and convenient. Thirdly, the drilling drainage operation of the intracranial hematoma cavity is assisted by three-dimensional orientation, and the minimally invasive operation adopts a punching mode, so that the wound is smaller, but the pressure cannot be reduced sufficiently in time, and the reliable hemostasis cannot be performed under the direct-view condition.

The operation of opening the skull by the ossicular window can be completed under the assistance of a microscope or a neuroendoscope, but due to the small opening range of the cortex under the ossicular window, the hematoma can not be displayed clearly near the microscope, and if bleeding which is difficult to stop occurs in the operation, the cortex wound surface must be enlarged so as to ensure a satisfactory operation field. The neuroendoscope can provide high-intensity illumination for approaching observation, so that hematoma and adjacent tissues can be clearly identified, the hematoma can be accurately treated, and the hematoma range can be intuitively observed to ensure reliable hemostasis. The chinese patent document with application number 202221676938.1 discloses an endoscopic sleeve device with suction function, the use method of the sleeve device is as follows: the front end of a sleeve pipe with a core rod and a suction tube is inserted into a hematoma cavity, then the core rod is pulled out of the sleeve pipe from the rear end through a handle rod, an endoscope channel is formed in the sleeve pipe, an endoscope and bipolar electrocoagulation can be inserted into the endoscope channel to perform hematoma removal and hemostasis operation, and the suction tube is pushed to the front end until the extension section extends out of the end of the sleeve pipe during hemostasis, and a suction hole is matched with a negative pressure suction device to suck blood so as to provide an operation field for bipolar electrocoagulation hemostasis.

In the existing neuroendoscopic hematoma removal, a proper sleeve is usually placed in a hematoma cavity, and hematoma suction and hemostasis are carried out in the inner space of the sleeve. In the operation process, the endoscope and the aspirator are placed into the hematoma cavity through the sleeve to pump out hematoma, and if clear active hemorrhage exists, bipolar electrocoagulation is needed to carry out electrocoagulation hemostasis. When the bleeding of the active bleeding is stopped, the assistant can hold the glasses to cooperate, and the operator can operate the bleeding by 'both hands' under the direct vision of the endoscope. The hand-held endoscope is used for exposing the broken end of the blood vessel with active bleeding for the operator, the left hand of the aspirator is used for holding the bipolar electrocoagulation by the right hand for 'two hands' operation hemostasis.

In the operation process, the defects of mutual interference among 3 instruments of an aspirator, an endoscope and bipolar electrocoagulation in a working channel exist, and the problem of asynchronous operation cooperation of two people exists.

Also, the terms "upper", "lower", "left", "right", "middle", and the like are used herein for descriptive purposes only and are not intended to limit the scope of the invention for modification or adjustment of the relative relationships thereof, as they are also considered within the scope of the invention without substantial modification to the technical context.

As shown in fig. 1, the cerebral hemorrhage mirror with adjustable and fixed suction structure of the present embodiment includes an insertion portion 100, an operation portion 200, and a connection portion 300, wherein the insertion portion 100 is of a rigid structure, is inflexible, and the connection portion 300 is connected to the bottom end of the operation handle 220 of the operation portion 200 through a cable 230.

As shown in fig. 2-1 and 2-2, the front end of the insertion portion 100 is a head end seat 101, and a plurality of through holes are formed in the head end seat 101, wherein the three through holes are respectively communicated with a camera channel 110 and two groups of light source channels 120, and are used for installing a camera and two groups of light sources, and the light sources are preferably optical fibers or LED illumination.

The other three through holes are used to connect the instrument channel 130, the blood aspiration cannula channel 140, and the flush/overflow channel 150, respectively.

Further, the rear of the head end seat 101 may be connected with an insert portion main sleeve, and the insert portion outer sleeve wraps the rear end of the head end seat 101 and the insert portion main sleeve, and the insert portion outer sleeve plays a role of firmly connecting and flattening the insert portion 200 without edges and corners, so as to avoid damage to brain tissues.

The operation portion is constituted by a passage port 210 and an operation handle 220, and the operation handle 220 includes a handle lower case 221 and a handle top cover 222. Port 210 includes instrument insertion port 211, a blood aspiration cannula port 212, and an irrigation/spill port.

As shown in fig. 3-1 and 3-2, the instrument insertion opening 211 is arranged at the upper end to facilitate insertion of the instrument such as the electric coagulation device. A flushing/overflowing passage port and a blood sucking cannula passage port 212 are arranged below the instrument insertion port 211, the port of the flushing/overflowing passage port is a luer connector, and the port of the blood sucking cannula passage port 212 is a blood sucking cannula insertion connector 213. Instrument insertion opening 211 is coaxially disposed with instrument channel 130 to ensure that instrument channel 130 is straight and does not bend.

Because the operator needs to control the length of the electric coagulator extending out of the cerebral hemorrhage lens end at any time, the electric coagulator needs to be capable of freely moving in the channel. In this embodiment, instrument channel 130 communicates with instrument insertion port 211, and electrocoagulator 250 is slidably disposed within instrument channel 130 with the head end of electrocoagulator 250 extending out of head end seat 101.

In order to meet the requirement that the suction work is synchronously completed when an operator holds the endoscope by one hand, the blood suction cannula and the endoscope are required to be fixedly connected.

In this regard, the blood sucking cannula passage 140 of the present embodiment communicates with the blood sucking cannula passage port 212, the blood sucking cannula insertion connector 213 is mounted to the blood sucking cannula passage port 212, the locking mechanism is provided on the blood sucking cannula insertion connector 213, and the length of the blood sucking cannula 240 extending out of the head end seat 101 is regulated by the blood sucking cannula 240 through the locking mechanism and locked in the blood sucking cannula passage 140 through the locking mechanism.

When the device is used, after the blood sucking cannula is inserted into the cerebral hemorrhage mirror, the head end of the blood sucking cannula extends out of the cerebral hemorrhage mirror head by a proper distance under the image guidance of the cerebral hemorrhage mirror, then the blood sucking cannula is locked through the locking mechanism on the blood sucking cannula insertion connector, and in the operation process, the length of the blood sucking cannula extending out of the cerebral hemorrhage mirror head can be adjusted by the operator at any time through the locking mechanism.

The cerebral hemorrhage mirror blood sucking function structure of this embodiment is different from current cerebral hemorrhage mirror and only increases a blood sucking channel alone to use negative pressure equipment at this passageway rear end, utilize the endoscope from the blood sucking channel of taking to inhale blood, the blood sucking channel terminal surface is unanimous with the camera lens terminal surface promptly, and the drawback of this kind of scheme lies in: when sucking blood, the cerebral hemorrhage lens end needs to be clung to or partially extend into hematoma, and the lens is easily blocked by coagulated blood or mucus, so that the operation field cannot be seen clearly, repeated flushing is needed, and the operation difficulty is increased.

In this embodiment, the fixed connection of blood sucking cannula and mirror body is realized to blood sucking cannula passageway cooperation blood sucking cannula insertion joint to and the manual adjustable function of extension distance, has avoided the problem that the camera lens was sheltered from by blood, mucus.

Further, in order to facilitate removal of the side hematoma, the blood sucking cannula adopts a flexible structure capable of being bent at a certain angle, namely, the blood sucking cannula can be bent manually to be shaped, and bending angle adjustment can be carried out through structures such as snake bones.

As one embodiment of the locking mechanism, as shown in fig. 4-1 to 4-4, the locking mechanism includes a blood sucking channel interface 214 and a locking wheel 215, wherein an end of the blood sucking cannula 240 away from the head end seat 101 extends out of the blood sucking channel interface 214, and the locking wheel 215 is sleeved on the blood sucking channel interface 214 and locks the blood sucking cannula 240 by rotating.

Specifically, the portion of the blood sucking channel interface 214, which is inserted into the locking wheel, is an elliptic cylinder structure, a slot 2141 is formed in the cylinder extending from the front end surface along the length direction of the cylinder, and a locking hole 2151 matching with the elliptic cylinder of the blood sucking channel interface is formed in the center of the locking wheel 215.

When the blood sucking cannula needs to be locked, the locking wheel is rotated by 90 degrees, and the elliptic cylinder of the blood sucking channel connector is slotted and closed to compress the blood sucking cannula, so that the locking is completed; the locking wheel is rotated in the opposite direction, namely unlocking.

Further, in order to prevent the locking member from falling off, the blood sucking channel interface 214 is provided with a step 2142 along the circumferential direction, and the opening of the locking hole 2151 near one side of the blood sucking channel interface 214 is provided with a protruding edge 2152, where the protruding edge 2152 abuts against the step 2142.

In order to facilitate the operator to push the locking wheel, as shown in fig. 6-3 to 6-5, the profile of the locking wheel can be modified: the locking wheel 215 is provided with a triangular push block 216 extending radially outwards. Compared with the circular arc locking wheel, the locking wheel with the triangular pushing block is easier to push, improves convenience and is also beneficial to improving comfort of use of a user.

Excessive rotation of the locking wheel during surgery, for example, can damage components and instruments. For this, the locking mechanism can be further improved: a limiting block 217 is arranged on the end surface of one side of the locking wheel 215, which is close to the blood sucking channel interface 214, and a rotating path 218 for the limiting block 217 to move is arranged on the blood sucking channel interface 214 along the circumferential direction.

Through increasing the rotation path of the locking wheel, the rotation range of the locking wheel is limited, so that the locking wheel can be ensured to rotate and lock the blood sucking cannula, and excessive rotation of the locking wheel can be avoided, and components and instruments are damaged.

Because of the different requirements on the inner diameter of the channel of the blood sucking cannula, the inner diameter of the channel is sometimes required to be enlarged so as to conveniently suck out larger hematoma. Therefore, the arrangement of the channels on the operating portion needs to be changed, and the handle structure also needs to be changed accordingly.

As an arrangement of the channels, as shown in fig. 6-1 and 6-2, the diameter of the blood sucking cannula channel port 212 is larger than the diameter of the instrument insertion port 211 and the flushing/overflowing channel port, and the blood sucking cannula channel port 212 is arranged above the instrument insertion port 211 and the flushing/overflowing channel port. Accordingly, the present embodiment provides another operating handle structure including a handle housing 223, a handle side cover 224, and a handle end cover 225.

The cerebral hemorrhage mirror of the embodiment combines the endoscope, the aspirator and the electrocoagulator into a whole by adding the channel of the electrocoagulation and blood suction assembly, and the blood suction assembly can be fixedly connected with the mirror body. The left hand of the operator holds the cerebral hemorrhage mirror of the proposal, can synchronously complete the tasks of attraction and illumination, vacates the blood vessel broken end of the electric coagulation active hemorrhage in the working channel corresponding to the bipolar electric coagulation endoscope used by the right hand. The cerebral hemorrhage mirror of the embodiment can be operated by one operator, so that the defect that three instruments of an aspirator, an endoscope and bipolar electrocoagulation are mutually interfered in a working channel is avoided, the problem that the operation cooperation of two persons is asynchronous is also avoided, and the advantages of good illumination and clear amplification of the operation of the two hands of a microsurgery operator and the operation of the nerve endoscope are concentrated.

The invention and its embodiments have been described above by way of illustration and not limitation, and the invention is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present invention.
