The locking protrusion 225 can connect the first combining portion 2211 and the second combining portion 2221 by passing through the through hole, so as to keep the first sealing member 221 and the second sealing member 222 in a mutually overlapped state during the installation process, thereby facilitating the production and assembly.
Referring to fig. 2 of the specification, the valve seat 211 has a mounting groove 2110, and the channel sealing valve 22 is mounted to the mounting groove 2110; the valve seat 211 further has a first limit groove and a second limit groove communicated with the mounting groove 2110.

It should be noted that a connecting line between the first limiting portion 226 and the second limiting portion 227 of the channel sealing valve coincides with an extending direction of the opening length of the "i" shaped second opening 2220, and a connecting line between the first limiting groove and the second limiting groove of the valve seat 211 coincides with a connecting line between the first limiting portion 226 and the second limiting portion 227. The valve seat 211 is provided with the first limiting groove and the second limiting groove, so that the channel sealing valve 22 can be pre-installed on one hand, and the valve seat 211 and the locking seat 212 can be assembled conveniently; on the other hand, it is possible to maintain a certain positional relationship between the second seal 222 and the valve seat 211 such that the second opening 2220 of the second seal 222 is vertically mounted to the valve seat 211.
Further, the predetermined position of the valve seat 211 has an assembly groove, and the predetermined position of the locking seat 212 has an assembly protrusion adapted to be fitted into the assembly groove.

The preset position of the valve seat 211 is provided with an installation mark for enabling the linear second opening 2220 to be vertically installed corresponding to the hysteroscope body 1 in the process of installing the channel sealing mechanism 2 on the hysteroscope body 1.
It should also be noted that the mechanical channel of the locking seat 212 is of non-circular design, ensuring that the working device 3, which is not symmetrical at any angle (e.g. loop, hook), can enter and exit at a predetermined angle during insertion and removal of the working device 3. Accordingly, the customized motor needs to be designed to be non-circular to match the mechanical channel of the locking seat 212, and has simple structure, low cost and high process stability.
During the insertion of the working device 3, the second opening 2220 of the second seal 222 is in a closed state during the process of the head end of the device body passing through the first seal 221, which can prevent the liquid in the working channel 10 from leaking during the process of the head end of the device body passing through the first seal 221. After the head end of the instrument body passes through the first seal 221, the instrument body fills the first opening 2210 of the first seal 221 during passage through the second seal 222, thereby preventing liquid within the working channel 10 from leaking during passage of the instrument body through the second seal 222.
In the process of withdrawing the working device 3, after the device body withdraws from the second sealing member 222, the second opening 2220 of the second sealing member 222 is automatically switched to a closed state, so as to cut off the communication between the working pipe 10 and the buffer cavity 2230; at this point, the instrument body still fills the first opening 2210 of the first seal 221 and liquid still does not leak. After the instrument body exits the first seal 221, only a small amount of fluid within the buffer cavity 2230 leaks out.
Preferably, the end of the working pipe 10 is made of PEEK material, so that the end of the working pipe 10 can be prevented from being damaged in the working process of the working device 3, and the current can be isolated to prevent the occurrence of leakage accidents.
Example 2
Referring to fig. 5 in the specification, a second preferred embodiment of the channel sealing mechanism of the all-purpose hysteroscope provided by the present invention is illustrated, and the channel sealing mechanism of the all-purpose hysteroscope of the second preferred embodiment is different from the above preferred embodiments in that, in the second preferred embodiment, the channel sealing mechanism further includes a sleeve component installed on the working instrument 3, and the sleeve component can prevent the head end of the working instrument 3 from contacting the channel sealing mechanism 2 during the process of the working instrument 3 passing through the channel sealing mechanism 2, so as to provide protection for the head end of the relatively precise working instrument 3.
Referring to fig. 5 in the specification, in particular, the omnipotent hysteroscope further includes a sleeve assembly 4, where the sleeve assembly 4 is adapted to be mounted on the instrument body 31 of the working instrument 3, and is used for protecting the head end of the instrument body 31 during the process of mounting the instrument body 31 of the working instrument 3 on the working pipeline 10.
Further, the sleeve assembly 4 comprises a sleeve 41 and an elastic member 42, the sleeve 41 surrounds and forms an instrument channel 40, and the elastic member 42 is mounted to the instrument channel 40 of the sleeve 41. The tool body 31 of the working tool 3 can be passed through the tool channel 40 to mount the sleeve assembly 4 to the working tool 3.
Further, the apparatus body 31 has a first positioning portion 51, and when the sleeve assembly 4 is mounted on the working apparatus 3, the first positioning portion 51 can contact with the elastic member 42, so that the working apparatus 3 can drive the sleeve assembly 4 to move together. When the first capture portion 51 of the device body 31 is not moved in the sleeve 41 to compress the elastic member 42, the head end of the device body 31 is located in the device channel 40 of the sleeve 41; when the first capture portion 51 of the device body 31 moves in the sleeve 41 and compresses the elastic member 42 by a compression amount greater than a preset value, the head end of the device body 31 moves out of the device channel 40 of the sleeve 41.
Further, the working channel 10 further has a second positioning portion 52 therein, the second positioning portion 52 is disposed adjacent to and in the same straight line with the channel sealing mechanism 2, the sleeve 41 of the sleeve assembly 4 can contact with the second positioning portion 52 after passing through the first sealing element 221 and the second sealing element 222 of the channel sealing mechanism 2, and the second positioning portion 52 can limit the movement depth of the sleeve 41 in the working channel 10, so that the first positioning portion 51 of the device body 31 can compress the elastic element 42 in the sleeve 41, and the working device 3 can move to the outside of the device channel 40 of the sleeve 41.
Preferably, in the present preferred embodiment, the second opening 2220 of the second seal member 222 of the passage sealing mechanism 2 is in a cross shape. Preferably, the first sealing member 221 and the second sealing member 222 are made of medical silicone material.
Aligning the instrument body 31 together with the sleeve assembly 41 with the working channel 10 during insertion of the working instrument 3, the sleeve 41 of the sleeve assembly 4 first contacting the first and second seals 221 and 222 of the channel sealing mechanism 2 and passing through the first and second seals 221 and 222 of the channel sealing mechanism 2 in sequence during pushing forward the instrument body 31 and the sleeve assembly 41; continuing to push the tool body 31 of the working tool 3 forward, the sleeve 41 contacting the second detent 52, and the sleeve 41 stopping moving in the working channel 10; the instrument body 31 is pushed forward, and the head end of the instrument body 31 extends out of the sleeve 41 to work.
It should be noted that the head end of the device body 31 is retained in the sleeve 41 until the sleeve 41 is not in contact with the second detent 52 in the working channel 10. During the process that the sleeve 41 contacts with the first sealing element 221 and the second sealing element 222 of the channel sealing mechanism 2 and passes through the first sealing element 221 and the second sealing element 222 of the channel sealing mechanism 2, the head end of the instrument body 31 does not contact with the first sealing element 221 and the second sealing element 222 of the channel sealing mechanism 2, so that the head end of the instrument body 31 can be effectively protected.
Similarly, during the process of withdrawing the working device 3, as the device body 31 is withdrawn, the elastic member 42 in the sleeve 41 gradually recovers to its original shape, and the head end of the device body 31 gradually enters the sleeve 41; as the working device 3 is continuously withdrawn, the head end of the device body passes through the first sealing element 221 and the second sealing element 222 of the channel sealing mechanism 2 under the protection of the sleeve 41 of the sleeve assembly 4, and the withdrawing operation of the working device 3 is completed.
Further, the distance between the second capture portion 52 and the channel sealing mechanism 2 is greater than the length of the sleeve 41, and when the sleeve 41 is in contact with the second capture portion 52 during the insertion of the working device 3, the sleeve 41 is completely located between the second capture portion 52 and the channel sealing mechanism 2, and the first seal 221 of the channel sealing mechanism 2 is in contact with the device body 31, so as to prevent liquid leakage.
It should be noted that the rear wall of the sleeve 41 is connected to the apparatus body 31 in a sealing manner, so that during the process that the head end of the sleeve 41 is in contact with the first sealing element 221 and the second sealing element 222 of the channel sealing mechanism 2 and passes through the channel sealing mechanism 2, liquid enters the sleeve 41 and leaks through the connection between the sleeve 41 and the working apparatus 3. The sealing mechanism at the joint of the sleeve 41 and the working instrument 3 is a medical silica gel pad.
It should be noted that, during the insertion of the working device, after the sleeve 41 contacts the second positioning portion 52, the working device 3 is further pushed forward, the sleeve 41 stops moving, and the first positioning portion 51 of the working device 3 compresses the elastic member 42. During the process of withdrawing the working device 3 from the working channel 10, after the elastic member 42 in the sleeve 41 recovers its original length, the first capture portion 51 on the device body 31 contacts the rear wall of the sleeve 41 and can pull the sleeve 41 away through the first sealing member 221 and the second sealing member 222 of the channel sealing mechanism 2.
With reference to fig. 6 and 7 of the specification, a variant of the second preferred embodiment of the hysteroscope provided by the present invention is illustrated, in which the elastic member 42 and the sleeve 41 of the sleeve assembly 4 are arranged outside the sleeve 41 along a straight line.
Referring to fig. 6 and 7 of the specification, the elastic member 42 is located between the sleeve 41 and the first capture portion 51.
