[0039] In the embodiment, as shown in Figures 1-2 and Figure 4 , when the operator clamps the coagulation handle 10 to clamp or coagulate the tissue, the closing action of the handle triggers the triggering end 41 of the dripping water adjusting and controlling assembly, and the movable column 52 arranged on the mounting block 51 drives the lever 53 to transmit to make the spherical abutting block 55 release the water guide hose, so as to start dripping water; after the handle is released, the squeezing end on the spherical abutting block 55 restores the extrusion of the hose to stop dripping water, which solves the problem of operation interruption in the operation caused by the additional operation of the operator to control the switch to control the dripping water, ensures continuous wetting during coagulation, and stops in the non-operation state, which significantly improves the operation efficiency and safety.

[0040] In some embodiments, the dripping water adjusting and controlling assembly can adopt a combined structure of a micro pinch valve and a control switch. The structure includes a control switch fixed in the inner side of the coagulation handle 10 and a micro pinch valve, and the micro pinch valve is internally provided with a channel for accommodating the water guide hose. In this embodiment, when the coagulation handles 10 are close to each other and clamped, the control switch is extruded to trigger, sends an electric control signal to the micro pinch valve, and the micro pinch valve releases the water guide hose after receiving the electric control signal to realize dripping water; when the coagulation handles 10 are released, the control switch is reset, and the micro pinch valve restores the extrusion state of the water guide hose to stop dripping water.

[0041] Specifically, as shown in Figures 1-2 , two water guide hoses are arranged, which are arranged in the water guide pipe slots 12 of the pair of coagulation handles 10 respectively;
