[0024] Example 1

[0025] See also Figure 1-Figure 3A length-controllable electrocoagulation hemostatic knife comprises a knife handle 1 and a hemostatic knife body 5. The two ends of the hemostatic knife body 5 are fixedly connected with a positive conductive column 3 and a negative conductive column 4. The front end of the knife handle 1 is provided with a fixing column 2, and the rear end is provided with a cover 11. A battery 8 is provided inside the knife handle 1. The cover 11 is used to encapsulate the battery 8. The two ends of the battery 8 are respectively provided with a positive connecting conductive sheet 81 and a negative connecting seat 82. A pressing portion 6 is provided at the front end of the outer side of the knife handle 1. One end of the positive connecting conductive sheet 81 is connected to the negative connecting seat 82. The positive conductive column 3 and the negative conductive column 4 are connected to the battery 8, and the other end extends to the bottom of the pressing part 6. The positive conductive column 3 and the negative conductive column 4 are set in the fixed column 2 in a sliding connection manner. The blade handle 1 is provided with a pushing component for pushing the positive conductive column 3 and the negative conductive column 4 to translate synchronously, wherein the pushing component includes a slider 7, the positive conductive column 3 and the negative conductive column 4 are fixedly set on the slider 7, the slider 7 is slidably connected to the side wall of the blade handle 1, and the side wall of the blade handle 1 is provided with a slide groove 12 adapted to the slider 7. The pushing component can push the positive conductive column 3 and the negative conductive column 4 to translate together, thereby realizing the controllability of the length of the hemostatic blade body 5, and the length of the hemostatic blade body 5 can be adjusted according to the requirements of the surgical procedure. In order to make the positive conductive column 3 and the negative conductive column 4 have a certain damping property during the movement, a damping ring 21 is fixed at the inner end of the knife body handle 1. The damping ring 21 is a rubber ring. The damping ring 21 is sleeved on the positive conductive column 3 and the negative conductive column 4, and plays a certain damping role on the positive conductive column 3 and the negative conductive column 4 during the sliding process. At the same time, it plays a certain limiting and fixing role in the non-moving state.

[0026] In order to ensure that the movement of the positive conductive column 3 and the negative conductive column 4 does not affect the power supply, a conductive tube 83 is fixedly provided on the negative connecting seat 82 at a position corresponding to the negative conductive column 4. The negative conductive column 4 is inserted into the conductive tube 83 to form a sliding connection structure in the tube. The length of the conductive tube 83 is greater than the maximum displacement stroke of the slider 7. During the movement, the negative conductive column 4 always remains connected to the conductive tube 83 to ensure the connectivity of the negative power supply.

[0027] The positive conductive column 3 inside the knife body handle 1 is located below the pressing part 6, and the pressing part 6 is fixed on the free end of the positive connecting conductive sheet 81. A conductive contact 84 is provided at the bottom of the free end of the positive connecting conductive sheet 81, and the conductive contact 84 is suspended above the positive conductive column 3. When operating, the pressing part 6 is pressed down to make the conductive contact 84 contact the positive conductive column 3 to form a passage, and the hemostatic knife body 5 is powered on to work. After releasing the pressing part 6, the conductive contact 84 is separated from the positive conductive column 3 under the elastic action of the positive connecting conductive sheet 81, forming a short circuit, and the hemostatic knife body 5 is powered off and stops working.

[0028] The length-controllable electrocoagulation hemostatic knife of the utility model has a simple structure and can realize the length control of the electrocoagulation head. The pushing component and the conductive tube 83 and the conductive contact 84 matched with the pushing component can ensure good conductivity when the positive conductive column 3 and the negative conductive column 4 are pushed to translate. The translateable hemostatic knife body 5 can adapt to the length requirements of the hemostatic knife body 5 for different surgical procedures, which is convenient for doctors to operate and use.
