The electrode connector 3 is fixedly connected to the end of the core rod 1 away from the handle 11, and the spring tube 4 is connected to the end of the electrode connector 3.

[0026] A clamp inspection mechanism 5 is connected to the end of the spring tube 4 away from the electrode connector 3. The clamp inspection mechanism 5 is used to perform surgery on the lesion area. The clamp inspection mechanism 5 includes a clamp head frame 51 fixed to the end of the spring tube 4, and a clamp head group installed at the end of the clamp head frame 51. The clamp head group consists of a first clamp head 52 and a second clamp head 53. The first clamp head 52 and the second clamp head 53 are hinged so that the first clamp head 52 and the second clamp head 53 can be opened and closed.

[0027] At the same time, the electrode connector 3 is suitable for connecting with a high-frequency electric knife to output a high-frequency current, and the high-frequency current is led out of the clamp head group through the spring tube 4, so that the clamp head group performs electrocoagulation hemostasis on the lesion area;

[0028] like Figure 1-Figure 3 As shown, a driving unit is connected to the end of the clamp head group close to the clamp head frame 51, and the driving unit is used to control the opening and closing of the clamp head group. The driving unit includes a driving handle 2 arranged on the core rod 1, and a slider 21 installed inside the driving handle 2, and a slide groove 12 adapted to the slider 21 is provided on the core rod 1, and the driving handle 2 is sleeved on the core rod 1, so that under the cooperation of the slider 21 and the slide groove 12, the driving handle 2 can be driven to move along the slide groove 12, and a limiting block 13 is provided in the slide groove 12 near the handle 11, and a stopper (not shown in the figure) is fixed in the slide groove 12 away from the handle 11, and the limiting block 13 is used to limit the movement of the slider 21;

[0029] At the same time, a pull rod 22 is fixedly connected to the end of the slider 21, and the pull rod 22 extends toward the inside of the spring tube 4 and forms an extended end 221, and two sets of cables 23 are fixedly connected to the end of the extended end 221, and the two sets of cables 23 are respectively connected to the ends of the first clamp head 52 and the second clamp head 53, and the two sets of cables 23 are made of metal, and a spring (not shown in the figure) is arranged between the slider 21 and the stopper, and the spring pulls the slider 21;

[0030] When the driving handle 2 moves toward the handle 11, the slider 21 moves in the slide groove 12, and the movement of the slider 21 pulls the spring to extend, and at the same time drives the cable 23 to move toward the spring tube 4 through the pull rod 22, and the cable 23 pulls the clamp head group, so that the first clamp head 52 and the second clamp head 53 are close to each other, and the clamp head group is in a closed state;

[0031] When the driving handle 2 is slowly relaxed, the slider 21 is pulled toward the stopper under the action of the spring, and the movement of the slider 21 drives the pull rod 22 to move, and indirectly extends outward from the clamp head frame 51 through the pull cable 23, so that the first clamp head 52 and the second clamp head 53 are separated from each other. At this time, the clamp head group is in an open state (initial state);

[0032] like Figure 2-Figure 4As shown, a clamp pushing mechanism 6 is installed on the clamp head frame 51, and the clamp pushing mechanism 6 is used to push the clamp out. The clamp pushing mechanism 6 includes an inner tube 61 fixed on the clamp head frame 51, and the inner tube 61 extends toward the connection between the first clamp head 52 and the second clamp head 53 to form a clamp outlet end (clamp inlet end), and the inner tube 61 stores the clamp;

[0033] At the same time, a guide rod 62 is also arranged in the inner tube 61, and the guide rod 62 extends toward the slide groove 12 at the core rod 1 and is connected to a push handle block 63, and the push handle block 63 is slidably installed in the slide groove 12, and the push handle block 63 is between the handle 11 and the limit block 13, and the guide rod 62 sequentially penetrates the protruding end 221, the pull rod 22 and the slider 21, and the guide rod 62 is suitable for moving in the protruding end 221, the pull rod 22 and the slider 21, and a push plate 621 is arranged at the end of the guide rod 62 in the inner tube 61, and the push plate 621 is used to push the clip in the inner tube 61 out of the inner tube 61;

[0034] At the same time, a groove adapted to the clamp is provided on the clamp head group, wherein a portion of the groove in the first clamp head 52 is a first groove, and a portion of the groove in the second clamp head 53 is a second groove, and a stopper 54 for resisting and limiting the clamp is provided inside the first groove of the first clamp head 52 and the second groove of the second clamp head 53;

[0035] When the wound of the lesion area needs to be closed, the forceps head group is in a closed state, and the push handle block 63 is driven to slide in the slide groove 12, and the push plate 621 on the guide rod 62 is driven to slide by the push handle block 63, so that the clip in the inner tube 61 is extended outward from the inner tube 61, and the extended clip is moved into the groove of the forceps head group, and the end of the clip is against the blocking bar 54 of the first forceps head 52 and the blocking bar 54 of the second forceps head 53;

[0036] At the same time, the driving handle 2 is slowly loosened to drive the first clamp head 52 and the second clamp head 53 to slowly open through the cable 23. At this time, the clamp opens synchronously with the first clamp head 52 and the second clamp head 53 due to its own elastic force. After the first clamp head 52 and the second clamp head 53 reach the required opening degree, the first clamp head 52 and the second clamp head 53 are moved to the lesion area, and then the driving handle 2 is pulled, and the first clamp head 52 and the second clamp head 53 are driven to slowly close through the cable 23, and the first clamp head 52 and the second clamp head 53 squeeze the clamp so that the clamp clamps the lesion, thereby achieving the closure of the wound surface of the lesion area;

[0037] In summary, by arranging a clamp in the inner tube 61, under the action of the guide rod 62 and the push plate 621, the clamp of the inner tube 61 is pushed into the groove of the forceps head group, and under the cooperation of opening and closing between the first forceps head 52 and the second forceps head 53, the wound of the lesion area is closed, thereby achieving the effect of the thermal biopsy forceps closing the wound of the lesion area.
