[0030] like Figure 1As shown, a water-electric composite cutter head of a preferred embodiment of the utility model comprises: a shell 1, the shell 1 is a shell having an accommodating cavity inside, and an electric knife mechanism 2 and a water knife mechanism 3 are accommodated in the shell 1; the electric knife mechanism 2 is fixed to the shell 1, and the electric knife mechanism 2 comprises a connecting portion 21 and a cutting portion 22, and the connecting portion 21 is partially arranged in the shell 1, and the connecting portion 21 is connected to an external power supply mechanism 4 and supplies power to the cutting portion 22, and the cutting portion 22 extends from the shell 1 to the outside of the shell 1, and the connecting portion 21 comprises a high-frequency circuit and a circuit connector to supply power to the cutting portion 22, and the cutting portion 22 is used to cut tissue after being powered on, and smoke may be generated during the cutting process of the electric knife mechanism 2;

[0031] like Figure 1 As shown, the water jet mechanism 3 is partially fixed in the shell 1, and the water jet mechanism 3 includes a high-pressure pipe 31 and a return pipe 32.

There is a certain interval between the high-pressure pipe 31 and the return pipe 32. The high-speed water flow of the high-pressure pipe 31 forms a water jet in the interval, and the water jet can perform cleaning operations after cutting. The high-speed water flow between the outlet of the return pipe 32 and the inlet of the high-pressure pipe 31 will form a negative pressure space near them, which can absorb the smoke in the wound. When used during surgery: first, the electrosurgical knife mechanism 2 is used for electric cutting; secondly, the water jet mechanism 3 is used to clean the wound, and the cleared matter can be sucked out, and then the electrosurgical knife mechanism 2 is used again to accurately stop bleeding at the bleeding points caused by the water jet mechanism 3 cleaning the wound. The harmful smoke generated during the use of the electrosurgical knife mechanism 2 is sucked out by the negative pressure effect of the water jet mechanism 3, so that no smoke remains in the surgical area. The water-electric composite blade head of the present application has various cleaning methods, efficient cutting, accurate wound cleaning, no eschar remaining, and can also stop bleeding in time and automatically suck out the smoke, with efficient surgical effects and a clean surgical environment.
