[0012] Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a disposable water-injection high-frequency cutting knife. After the electrode wire passes through the channel formed between two moving plates and is connected to the electrode connector, the medical personnel can turn the connecting bolt. The connecting bolt drives the moving plate to move. After the moving plate comes into contact with the surface of the electrode wire, the electrode wire can be clamped and fixed, thereby ensuring the stability of the electrode wire after it is plugged into the electrode connector, avoiding loosening, improving the safety of the operation, and facilitating the use of the knife in medical surgery.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: a disposable water-injection high-frequency cutting knife, including a support part 1, a handle part 2 at one end of the support part 1, a water injection part 3 at the other end of the support part 1, and a cutting part 4 at the other end of the water injection part 3.

[0020] An electrode connector 7 is provided on the surface of the support part 1, and a support frame 9 is detachably provided on the side of the support part 1, located outside the other end of the electrode connector 7. Both ends of the support frame 9 are provided with movable plates 10 that move in the horizontal direction.

[0021] A channel adapted to the electrode wiring is formed between the two movable plates 10. Both ends of the support frame 9 are provided with connecting bolts 12, and the inner end of the connecting bolts 12 is rotatably connected to the outer side of the movable plate 10.

[0022] After the electrode wiring passes through the channel formed between the two movable plates 10 and connects to the electrode connector 7, the medical personnel can turn the connecting bolt 12. The connecting bolt 12 drives the movable plate 10 to move. When the movable plate 10 comes into contact with the surface of the electrode wiring, the electrode wiring can be clamped and fixed, thereby ensuring the stability of the electrode wiring after it is plugged into the electrode connector 7, avoiding loosening, improving the safety of the operation, and facilitating the use of the medical surgical work.
