[0037] Embodiment 1:

[0038] Please refer to Figure 1-4 , a rotatable electrode separation pliers that can turn, comprising:

[0039] A fixed handle 1, one side of the fixed handle 1 is rotatably installed with a movable handle 2 through a pin shaft 3, and an electrode connector 5 is installed on the top wall of the fixed handle 1;

[0040] A radian controller 6, the radian controller 6 is rotatably installed at one end of the fixed handle 1;

[0041] The forceps rod 7 is installed at one end of the radian controller 6, and an inner tube 9 is slidably installed in the forceps rod 7;

[0042] The bent-nose pliers 8 are installed at one end of the forceps rod 7, and the bent-nose pliers 8 are connected to the movable handle 2 through the inner tube 9.

[0043] The material of the inner tube 9 is flexible conductive metal. The materials of the fixed handle 1, the movable handle 2 and the radian controller 6 are all insulating engineering plastics. The fixed handle 1 and the movable handle 2 are provided with finger grooves that conform to ergonomics.

[0044] In this embodiment, the provided radian controller 6 can bend one end of the forceps rod 7, so that the bent-nose pliers 8 can bend within a certain angle range. At the same time, the provided radian controller 6 can drive the bent-nose pliers 8 to rotate at any angle of 360°, which can be flexibly adjusted according to the surgical needs, facilitating the grasping of tissues or foreign bodies during the operation, providing better operation control and surgical effect. The provided movable handle 2 is used in cooperation with the fixed handle 1. The movable handle 2 drives the bent-nose pliers 8 to work through the inner tube 9. The provided electrode connector 5 enables this device to have the function of electrocoagulation and cutting. The material of the inner tube 9 is flexible conductive metal and is in contact with the electrode connector 5, so that the electrode connector 5 can be electrically connected to the bent-nose pliers 8 to realize the electrocoagulation operation. The materials of the fixed handle 1, the movable handle 2 and the radian controller 6 are all insulating engineering plastics, which can prevent the operator from being electrocuted during use. The fixed handle 1 and the movable handle 2 are provided with finger grooves that conform to ergonomics, providing a comfortable holding feeling and stability.

[0045] Embodiment Two:

[0046] Please refer to Figure 3-8 , this embodiment provides a technical solution on the basis of Embodiment One: The radian controller 6 includes a radian adjustment shaft 61 that is hollowly arranged. One end of the radian adjustment shaft 61 is provided with an upper thread 62, and the other end of the radian adjustment shaft 61 is provided with a lower thread 63;

[0047] An upper adjustment sleeve 64 is screwed on the upper thread 62, and a through hole is opened at the axial center position of the upper adjustment sleeve 64;

[0048] A lower adjustment sleeve 65 is screwed on the lower thread 63, and a through hole is opened at the axial center position of the lower adjustment sleeve 65;

[0049] One end of the lower adjustment sleeve 65 is screwed with a handle runner 66;

[0050] The handle runner 66 is rotatably installed at one end of the fixed handle 1 through a bearing.

[0051] The outer diameter of the upper thread 62 is smaller than the outer diameter of the lower thread 63, and the length of the upper thread 62 is greater than the length of the lower thread 63.

[0052] The tong rod 7 includes a hard tube 71. An abutting block 72 is fixed to the outer side of one end of the hard tube 71, and an insulating sleeve 73 is sleeved on the outer wall of the hard tube 71. The upper adjusting sleeve 64 is slidably sleeved on the outer side of the insulating sleeve 73, and the length of the insulating sleeve 73 is greater than the length of the hard tube 71.

[0053] The bent-nose pliers 8 includes a mounting tube 81. One end of the mounting tube 81 is sleeved in the insulating sleeve 73, and a scissor mechanism 82 is installed at the other end of the mounting tube 81;

[0054] One end of the scissor mechanism 82 is symmetrically fixed with a plier head 83, and the other end of the scissor mechanism 82 is fixedly connected to one end of an inner tube 9.

[0055] The inner tube 9 is slidably sleeved in the hard tube 71. A connecting ball 10 is fixed to one end of the inner tube 9, and a spherical groove 4 matching the connecting ball 10 is formed in the top wall of the movable handle 2.

[0056] In this embodiment, the inner tube 9 slidably penetrates through the fixed handle 1 and the connecting ball 10 is stuck in the spherical groove 4. When the radian controller 6 is in use, through the forward and backward linear movement of the tong rod 7, the front end of the inner tube 9 inside the tong rod 7 is bent, thereby driving the front end of the tong rod 7 to bend, realizing a turn. Then, the radian is controlled by the screwing distance of the upper thread 62 of the radian adjusting shaft 61. When the tong rod 7 is rotated clockwise, it becomes straight, and when the tong rod 7 is rotated counterclockwise, it bends. The radian is controlled between 0 - 40°. The specific working principle is as follows: when the upper adjusting sleeve 64 is rotated counterclockwise, the radian adjusting shaft 61 axially moves backward (i.e., moves towards the fixed handle 1), the hard tube 71 connected to the radian adjusting shaft 61 moves backward linearly, the front end of the inner tube 9 inside the tong rod 7 abuts against the insulating sleeve 73, the inner tube 9 is squeezed and gradually bends. The bent-nose pliers 8 is connected to the front end of the insulating sleeve 73, and the force received by the inner tube 9 is transmitted to the insulating sleeve 73 by the bent-nose pliers 8 connected to the inner tube 9. Therefore, the front end of the insulating sleeve 73 is squeezed and bent; when the upper adjusting sleeve 64 is rotated clockwise, the radian adjusting shaft 61 axially moves forward, the tong rod 7 connected to the radian adjusting shaft 61 moves forward linearly, the front end of the inner tube 9 inside the tong rod 7 is gradually not squeezed, and the front bent part gradually becomes straight. At the same time, in this embodiment, by rotating the handle runner 66, the entire tong rod 7 can be driven to rotate, realizing driving the bent-nose pliers 8 to rotate at any angle of 360°.
