[0002] Currently, more and more open surgeries have been replaced by minimally invasive surgeries. Minimally invasive surgeries have many advantages, such as small surgical trauma, fast postoperative recovery, and beautiful abdominal incision scars. Therefore, minimally invasive surgery is an inevitable trend in the development of future surgical methods. In minimally invasive surgeries, in many cases where it is necessary to cut and coagulate human tissues, an electric hook needs to be used. Clinically, when using an electric hook, it needs to enter the human body through a trocar or other channels to perform operations such as electrocoagulation and electrocision on human tissues.

The outer tube of the electric hook head 8 is sleeved on the electric hook head support member 3. The connecting piece 10 is fixed to the assembled components through the connecting piece fixing pin 9 to complete the overall electric hook head assembly. A connecting piece 10 is fixedly sleeved on the outer wall of the connecting piece fixing pin 9. A transmission gear 11 is rotatably connected to the outer wall of the connecting piece 10.

An upper cover of the electrode rod 17 is fixedly connected to the outer wall of the outer tube of the electrode rod 18. An outer tube protective sleeve of the electrode rod 16 is fixedly sleeved on the outer wall of the outer tube of the electrode rod 18. The outer tube protective sleeve of the electrode rod 16 avoids the risk to human tissues caused by the operation of the electric hook head 1. A rotating member 19 is bonded to the outer wall of the outer tube of the electrode rod 18. A moving mechanism is provided on the outer wall of the rotating member 19. A connecting wire 31 is fixedly connected to the outer wall of the conduction needle 29. A circuit board 32 is inlaid inside the upper cover of the handle 36 and the lower cover of the handle 28. A cutting button 34 and a coagulation button 35 are slidably connected to the outer wall of the upper cover of the handle 36.

[0021] by Figure 1 , Figure 2 and Figure 4As shown, the moving mechanism includes a sliding base 20. The outer wall of the rotating member 19 is slidably connected to the outer wall of the sliding base 20. The outer wall of the sliding base 20 is fixedly connected to one end of the rack bar 14. A sliding base fixing pin 21 is fixedly connected to the outer wall of the sliding base 20. A positioning pin 22 is slidably connected to the outer wall of the sliding base 20. A spring 23 is sleeved on the outer wall of the positioning pin 22. A sliding base cover plate 24 is snap-connected to the outer wall of the sliding base 20. An anti-pull sleeve 25 is fixedly sleeved on the fixed sleeve of the upper cover 17 of the electrode rod. An anti-pull tube positioning pin 26 is slidably connected to the outer wall of the anti-pull sleeve 25. A conducting piece 27 is fixedly connected to the inner wall of the anti-pull sleeve 25. A handle lower cover 28 and a handle upper cover 36 are fixedly installed on the outer wall of the anti-pull sleeve 25. A conducting needle 29 is fixedly connected to the outer wall of the conducting piece 27. An elastic pad 30 is fixedly connected to the outer wall of the conducting needle 29. The elastic pad 30 is located inside between the handle lower cover 28 and the handle upper cover 36. The electrode rod assembly can rotate 360 degrees within the handle upper cover 36 and the handle lower cover 28. Dome sheets 33 are slidably connected to the outer walls of both the electrocision button 34 and the electrocoagulation button 35. The outer wall of the dome sheet 33 is fixedly connected to the outer wall of the circuit board 32. A cable 37 is fixedly connected to the outer wall of the circuit board 32. A circuit board protective sleeve 38 is fixedly connected to the outer wall of the circuit board 32.

[0022] Working principle: When in use, insert the plug on the cable 37 into the main unit, and insert the electrode rod assembly into the corresponding channel to enter the human body. When the instrument reaches the human body, if it is found that the electric hook head 1 is facing in the incorrect direction and the angle needs to be adjusted, the rotating part 19 can be rotated. At this time, the electrode rod assembly can rotate 360 degrees within the upper handle cover 36 and the lower handle cover 28. When the angle of the electric hook head 1 needs to be adjusted, push the sliding base cover plate 24 by hand to drive the sliding base 20 to move. Thus, the sliding base 20 drives the rack bar 14 to move. The rack bar 14 pushes the driving gear 13, the driving gear 13 pushes the transmission gear 11, the transmission gear 11 pushes the steering gear 7, and the rotation of the steering gear 7 drives the entire electric hook head assembly to rotate, realizing the rotation angle of the electric hook head 1. When the sliding base 20 moves, the positioning pin 22 inside the sliding base 20 will move accordingly. When it moves into the hole position on the rotating part 19, the hand movement stops, and the electric hook head assembly can stop at the corresponding angular position. If the position needs to be changed, just manually move the sliding base cover plate 24, and the electric hook head 1 will rotate. When the desired position is adjusted, press the electrocoagulation button 35 or the electrosection button 34, and the electric hook head 1 starts to work. The electrical energy output by the main unit is transmitted through the cable 37 to the circuit board 32, then to the connecting wire 31, then to the conduction needle 29, then to the conduction piece 27, then to the electric hook connecting wire 5, and finally to the electric hook head 1. The energy output of the electric hook head 1 acts on human tissues to achieve cutting and coagulation. The outer tube protective sleeve 16 of the electrode rod can avoid the risks caused by the electric hook head 1 to human tissues during operation, such as clamping normal human tissues during rotation or scratching normal human tissues with the rotating structure, and can also increase the leakage protection.
