Then, the first handle 101 is rotated to enable the first handle 101 to rotate towards the second handle 201, in the process that the first handle 101 rotates, the compression spring is compressed, the first handle 101 drives the rotating plate 22 to rotate anticlockwise, the rotating plate 22 drives the pushing bar 26 to move, and the pushing bar 26 pushes the bar-shaped blade 28 to move forwards in the first chute 501 and the second chute; under the action of the rotating plate 22 and the pushing bar 26, the cutter head 29 moves into the first guide groove 8 and the second guide groove to cut the electrocoagulation tissue. After the cutting of the electrocoagulation tissue is completed, the first handle head 101 is released, and the first handle head 101 is reset under the action of the compression spring to reset the rotating plate 22, the pushing bar 26 and the blade assembly.

The above embodiments are only preferred embodiments of the utility model and do not limit the scope of the utility model, so all equivalent changes or modifications made by the technical solution described in the patent claims are included in the scope of the utility model.
