The button 2 is composed of a spring 12, a button cap 13, a button rod 15, a first sealing ring 17, a second sealing ring 18, a third sealing ring 19 and a fourth sealing ring 20. See in particular fig. 3.
Wherein, the button cap 13 is connected with the button rod 15, and the spring 12 is sleeved on the button rod 15; the button rod 15 can move radially in the button seat 3 by pressing the button cap 13 to drive the button rod 15 to generate a compression force on the spring 12; next, the return force of the spring 12 returns the push-button lever 15 to the initial state.
The button rod 15 is provided with an air passage 35, an air/water feeding opening 14 and a suction opening 16 at the upper, middle and lower parts.
The air passage 35 is used to discharge air inside the push button 2 out of the push button 2 through the air passage in the initial state.
The suction opening 16 is matched with the negative pressure channel to form conduction of the negative pressure channel, the button rod 15 is pressed until the suction opening 16 at the bottom of the button rod 15 is connected with the negative pressure channel, and the negative pressure channel can transmit negative pressure to the clamp channel connecting pipe 9 through the suction opening 16, so that suction operation can be realized.
The first sealing ring 17, the second sealing ring 18, the third sealing ring 19 and the fourth sealing ring 20 are used for sealing different areas of the inner wall of the button seat 3.
The first sealing ring 17, the second sealing ring 18, the third sealing ring 19 and the fourth sealing ring 20 are arranged on the button rod 15 from top to bottom in sequence; a first seal ring 17 and a second seal ring 18 are sequentially provided on one side of the air/water feeding opening 14; the third gasket 19 and the fourth gasket 20 are sequentially provided on the other side of the air/water feeding hole 14.
The first sealing ring 17 and the second sealing ring 18 separate and conduct the air passage through the radial movement of the button 2 in the button seat 3; the third sealing ring 19 and the fourth sealing ring 20 are separated and communicated with the water channel through the continuous radial movement of the button 2 in the button seat 3.
Specifically, when the button is in the air supply state, at this time, the first sealing ring 17 and the second sealing ring 18 are not located on the air outlet 25 and the air inlet 21 on the button seat 3, and at this time, the air passage is in the conduction state; meanwhile, the third sealing ring 19 is matched with a water outlet hole 26 on the button seat to seal the water channel; in this state, the air supply operation can be realized.
When the water supply device is in a water supply state, the first sealing ring 17 and the second sealing ring 18 are matched with the air outlet 25 when the button 2 is pressed to the limiting step 28 at the bottom of the button seat 3, and meanwhile, the third sealing ring 19 blocks the air pressure release channel to block the air channel; at this time, the third sealing ring 19 and the fourth sealing ring 20 are not positioned on the water inlet hole 23 and the water outlet hole 26, and the water channel is conducted; in this state, the water supply operation can be realized.
The sealing scheme is not limited, the design of a part of sealing rings can be cancelled, a mechanical structure tightly matched with the inner hole of the button base 3 is added on the button rod 15, and the sealing effect is achieved through tight matching.
The following illustrates the working process of the present solution in specific application.
Referring to fig. 4, in the initial state of the installation of the button 2, the endoscope operating system discharges the external air out of the button 2 through the air passage of the air/water feeding opening 14 of the button rod 15 due to the operation of the button packing.
Referring to fig. 5, when the air supply function is needed, the finger blocks the air supply and water supply opening 14 of the button rod, and the air in the air source 32 rushes through the butterfly portion of the second sealing ring 18 and enters the air channel connecting pipe 11 under the action of the second sealing ring 18, so that the air supply function is operated to supply air to the patient.
At this time, the third sealing ring 19 is matched with the water outlet hole 26 on the button seat to seal the water channel, so that the air supply function is not influenced by the water supply function; meanwhile, the negative pressure release pipe 4 is communicated with the negative pressure source connecting pipe, and the suction force generated by the negative pressure source 34 is released through the negative pressure release pipe, so that the air supply function is not influenced by the work of the negative pressure source 34.
Referring to fig. 6, when the water supply function is needed during the operation, the user presses the button cap 13 with fingers to the position of the limit step 28 where the user feels a blocking feeling, at this time, the second sealing ring 18 is squeezed and deformed by the contraction of the inner wall of the button seat 3, the air cannot enter the air passage connecting pipe 11 through the butterfly portion of the second sealing ring 18, and at the same time, the air passage is blocked by the third sealing ring 19.
With the continuous operation of the air source 32, the pressure in the external water source 33 is increased because of the pressure of the air source 32, and at this time, the water in the water source 33 is sent to the button base 3 through the water source connecting pipe 7 and enters the water path connecting pipe 10, so as to realize the operation of supplying water to the body of the patient; meanwhile, due to the action of the third sealing ring and the fourth sealing ring, the water source cannot leak to the air source connecting pipe 6 and the negative pressure source connecting pipe 7.
When the endoscope operation system is in an initial state, an air supply state and a water supply state, the negative pressure source 34 is in a continuous working state, the negative pressure channel is connected with the opening of the air channel of the operation handle through the negative pressure source connecting pipe 8 and the negative pressure release pipe 5, the pressure generated by the negative pressure source 34 is released through the opening of the air channel in the operation handle 1, and the suction function cannot be generated to interfere the operation.
Referring to fig. 7, when the suction function needs to be realized, the finger presses the button cap 13 to the bottom, the forceps channel connecting pipe 9 is communicated with the negative pressure source connecting pipe 8 through the button rod suction opening 16, and the effusion in the body of the patient is sucked out under the action of the negative pressure. At this moment, air supply connecting pipe 6 and air flue release pipe 4 intercommunication, the produced pressure of air supply can release through air flue release pipe, because water source 33 carries through the pressure of air supply 32, so when realizing the suction function, can not carry out the realization that supplies gas, water supply function disturbed the suction function.
The endoscope operating handle air and water supply suction system formed by the scheme has the advantages that one button can simultaneously have the functions of air supply, water supply and suction, the convenience of single-hand holding operation of the endoscope operating handle is improved, the possibility of wrong installation when a plurality of buttons are installed is avoided, and meanwhile, the labor cost and the management cost of later maintenance of a hospital are also reduced.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
