DETAILED DESCRIPTION

[0023] To make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] When the control button 11 is pressed, the hook part 1311 works and the linkage part 21 of the protection push rod 2 moves forward at the same time, and the sleeve joint part 22 and the push part 23 are driven to move forward, so that the push part 23 moves away from the hook part 1311.

[0027] The electrocoagulation knife main body 1 can adopt the existing structure, when the control button 11 is pressed, the internal device of the electrocoagulation knife main body 1 works to control the metal tip of the hook part 1311 at the front end to generate high-frequency high-voltage current, when the metal tip contacts the body, the tissue can be heated, and the cutting and coagulation of the body tissue are realized, and the specific working principle belongs to the prior art, which will not be described here.

[0028] The utility model mainly improves the protection push rod 2. When the control button 11 is pressed, the linkage portion 21 moves forward, and the top pushing portion 23 is driven to move forward synchronously, the tissue near the hook portion 1311 of the front end of the electrocoagulation knife body 1 is pushed away from the hook portion 1311, and the tissue is prevented from contacting the metal tip of the hook portion 1311, thereby avoiding the risk of tissue damage. Therefore, the damage degree of normal tissue during the operation process can be significantly reduced, the safety of fine operation is improved, and more reliable protection is provided for the smooth development of surgical operation.

[0029] Moreover, the top pushing portion 23 can be located in front of the hook portion 1311 when not moving forward, and specifically can be attached to the front side of the hook portion 1311, so as not to affect the normal hooking and pulling action of the hook portion 1311.

[0030] Specifically, the electrocoagulation knife body 1 can include an electrocoagulation knife handle 12 and an electrocoagulation knife rod 13; the rear end of the electrocoagulation knife rod 13 is connected with the electrocoagulation knife handle 12; the front end of the electrocoagulation knife rod 13 is bent to form the hook portion 1311; the control button 11 is arranged on the electrocoagulation knife handle 12. The sleeve portion 22 is movably sleeved on the outer periphery of the middle part of the electrocoagulation knife rod 13.

[0031] In the embodiment, the linkage portion 21 is plate-shaped and attached to the top surface of the electrocoagulation knife handle 12 to facilitate forward sliding and avoid interfering with the holding and use of the electrocoagulation knife handle 12; and the front end of the linkage portion 21 is connected with the sleeve portion 22 through the tapered inclined plate 24 at the front end.

[0032] And as Figure 4 In the embodiment, the front end of the sleeve portion 22 of the protection push rod 2 can have a forwardly extending and tapered connecting portion 25, the front end of the connecting portion 25 is bent upward to form the top pushing portion 23, and the top pushing portion 23 is movably attached to the front side of the hook portion 1311. In this way, the size of the additionally equipped connecting portion 25 and top pushing portion 23 is adapted to the hook portion 1311, and does not interfere with the normal use of the hook portion 1311.

[0033] Again as Figure 3 And Figure 4 In the embodiment, the control button 11 can be movably arranged in the through hole 121 on the top of the electrocoagulation knife handle 12; and the control button 11 has two, which are the electrocoagulation button 11a and the electrocision button 11b distributed on the top of the electrocoagulation knife handle 12 in front and back. Figure 3 The internal structure of the electrocoagulation knife handle 12 is hidden, and the internal structure can adopt the prior art, which is not expanded here.

[0034] The control button 11 can be provided with a groove 111 in the front side of the middle part. The linkage 21 can be attached to the top surface of the coagulation handle 12 and provided with two movable holes 211 for the coagulation button 11a and the cutting button 11b. The movable hole 211 of the linkage 21 is provided with a slope 212 which is inserted into the groove 111.

[0035] The groove 111 of the embodiment is a triangular groove with a flat bottom and an inclined top. The slope 212 is a triangular slope.

[0036] With the structure, when the control button 11 is pressed, the groove 111 moves downward and pushes the slope 212 by the slope surface, which further pushes the linkage 21 forward, and further pushes the pushing part 23 forward. The structure is simple and convenient to use. The pushing part 23 can be pushed forward only by pressing the control button 11, which can protect other tissues while coagulating or cutting.

[0037] The linkage 21 can be connected with one end of the tension spring 3, and the other end of the tension spring 3 is connected to the rear side of the coagulation handle 12. Thus, the tension spring 3 can provide the elastic force for pushing the linkage 21 backward. When the control button 11 is released, the protection pushing rod 2 can be reset to the initial state under the elastic force of the tension spring 3, so that the slope 212 of the linkage 21 is inserted into the slope 111 of the control button 11, which is convenient for the next use.

[0038] Specifically, the rear side of the coagulation handle 12 can be provided with a cover 122, and the cover 122 and the top surface of the coagulation handle 12 can form an installation space 123 with an open front end.
