The two blades 20 are correspondingly installed inside the two forceps valves 13 and are in sliding fit with the forceps valves 13, so that the blades 20 can slide along the length direction of the forceps valves 13 to extend out or retract from the forceps tips 14, and the cutting edges of the two blades 20 are opposite, so that when the two forceps tips 14 are operated to perform approaching/separating actions, the two blades 20 move relatively, and a microscissing function can be realized. The two forceps flaps 13 are connected with a power supply through a cable and used for applying current to the forceps tips 14 to realize the electric coagulation hemostasis function, and the cable is provided with a second foot control switch 40 for controlling the application/disconnection of the current to the forceps tips 14. The inner end face of the forceps tip 14 is further provided with an anti-slip structure 15, the anti-slip structure 15 may be convex points, convex strips, grid-shaped protrusions, and the like, in this embodiment, the convex strips are shown in fig. 2, and the anti-slip structure 15 enables the electric coagulation forceps to be used as a clamp for clamping a suction apparatus and a brain cotton piece.
Because the length of the forceps flap 13 is long, in order to ensure the reliability of the shearing operation when the forceps flap is used as a micro-shear, the blades 20 are provided with magnetic structures to generate a certain adsorption effect after the two blades 20 are contacted, so that the two blades are well attached together, the specific magnetic structures can be magnetic sheets, magnetic powder layers or magnetic powder, the magnetic structures can be arranged on the blades 20 through the processes of inlaying, electroplating and coating, more specifically, on the blade body 22 of the blade 20, and the magnetic powder can also be directly dispersed in the material for manufacturing the blades 20, so that the manufactured blades 20 have certain magnetism.
The driving means 30 is arranged at the forceps flaps 13 for driving the blade 20 to extend or retract from the forceps tip 14. Referring to fig. 1 and fig. 3, the driving device 30 of the present embodiment includes: a rack 31 provided on the handle portion 21 of the blade 20, a gear device 32 for driving the rack 31, a pull cord 324 for pulling the gear 322 to rotate, and a first foot switch 33 for controlling the operation of the pull cord 324. The gear device 32 is fixed on the outer side of the forceps valve 13, the gear 322 is in driving fit with the rack 31 of the handle part 21, the pull rope 324 extends along the forceps valve 13 from the gear 322 device 32 to the forceps seat part 11, and then continues to extend to be connected with the first foot switch 33, and the forceps valve 13 is further provided with a guide rope ring 12 to hold the pull rope 324 on the forceps valve 13.

The housing 321 is fixedly engaged with the forceps flap 13, the gear 322 is supported in the housing 321 through the shaft 325, the tooth of the gear 322 passes through the gear hole and then is in transmission engagement with the rack 31, and the elastic member 327 is a tension spring, and is connected between the housing 321 and the gear 322, and is used for keeping the gear 322 in an initial state, in which the blade 20 is retracted in the forceps flap 13 (as shown in fig. 6). The plurality of direction changing portions 323 are fixed in the housing 321, and one end of the pulling rope 324 is connected to the gear 322, passes through the plurality of direction changing portions 323, passes through the rope hole 326, and is connected to the first foot switch 33. When the first foot-controlled switch 33 is stepped on, the pulling rope 324 pulls the gear 322 to rotate clockwise in fig. 3, so as to drive the handle portion 21 to move rightwards, and thus the blade 20 extends out from the forceps tip 14 (as shown in fig. 7); when the first foot switch 33 is released, the pulling force of the pulling rope 324 on the gear 322 is released, and under the action of the tension spring, the gear 322 is rotated and reset in the counterclockwise direction in fig. 3, and the knife handle 21 is driven to move leftwards, so that the knife blade 20 is reset and retracted into the forceps tip 14 (as shown in fig. 6). It will be appreciated that the above-described reset function can also be achieved by mounting a torsion spring on the support shaft 325 of the gear 322.
The gear 322 has a fan-shaped structure, so that the size of the whole gear device 32 is reduced, and the miniaturization is facilitated.

The application method of the bipolar electric coagulation forceps with the micro-shearing function comprises the following steps:
when the electric coagulation forceps are used, the blade 20 is in a retraction state and is kept in the forceps tips 14, as shown in fig. 6, so that the operation visual field is not influenced, and in this state, the electric current is controlled to be introduced into the forceps tips 14 through the second foot control switch 40, so that the electric coagulation hemostasis function is realized.
When the micro-scissors are used, the first foot control switch 33 is pressed, the pull rope 324 pulls the gear 322 to rotate clockwise in fig. 3, the blade 20 is driven to move rightwards in fig. 3, the blade 20 extends out from the forceps tips 14 and enters an extending state, as shown in fig. 7, in this state, the two forceps flaps 13 are controlled to open and close by hands, the two blades 20 are driven to shear, and the tissue is sheared. After completion, the first foot switch 33 is released, the gear 322 is rotated by the tension spring in the counterclockwise direction in fig. 3 to reset, and the driving blade 20 is reset, retracted into the forceps tips 14, and maintained in the retracted state, as shown in fig. 6.
When the forceps are used as a clamp, the forceps tips 14 are aligned with the suction apparatus or the collodion sheet, the two forceps flaps 13 are controlled by hands, and the suction apparatus or the collodion sheet is clamped to perform movement operation or other operations.
It can be seen that the bipolar coagulation forceps has at least the following effects: 1. the electric coagulation forceps have the function of micro-scissors, and the micro-scissors and the electric coagulation forceps do not need to be frequently replaced in the operation, so that the operation can be simplified, and the operation time can be shortened. 2.
