Referring to fig. 1 and 2, the front ends of the first and

second forceps arms

11 and 21 are respectively hinged with a first forceps head 13 and a second forceps head 23, so that the first and second forceps heads are allowed to move left and right, the first and

second forceps heads

13 and 23 and the first and second forceps

arms

11 and 21 form an included angle of 90 degrees, and thus the surgical wound can be conveniently stretched into, the second forceps head 23 and the second forceps arm 21 are hinged with each other, a doctor grasps and opens the first and second forceps handles 12 and 22, so that the first and

second forceps heads

13 and 23 move close to each other, and when pressing the first and second forceps handles 12 and 22, the first and

second forceps heads

13 and 23 move far from each other.

Referring to fig. 1, the first and

second clamp arms

11 and 21 are in a circular arc structure, so as to effectively increase the clamping area and make the clamping more stable.

Referring to fig. 1 and 2, a first sleeve 3 and a second sleeve 4 are movably disposed in each of the first and second bits 13 and 14, a first through hole 131 and a second through hole 231 penetrating through both ends are disposed in each of the first and

second bits
