[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 5 The utility model provides an embodiment: an orthopedic rongeur, comprising a pliers body assembly 1, a protective assembly 2 is provided at the connection part of the pliers body assembly 1, the pliers body assembly 1 comprises a pliers head 105, a pliers head 2 104, a handle 101 and a handle 2 102, the handle 101 and the handle 2 102 are fixedly connected with a rear baffle 1011 and a front baffle 1013, the rear baffle 1011 is located behind the front baffle 1013, the handle 1 101 and the handle 2 102 are located on the front baffle 1013 and the rear baffle 1011 is ... 11 is provided with an anti-slip groove 1012, the pliers head 105 and the pliers head 2 104 are rotatably connected to each other through a connecting shaft 106, the end of the handle 101 is rotatably connected to the end of the pliers head 105, the end of the handle 2 102 is rotatably connected to the end of the pliers head 2 104, the handle 101 and the handle 2 102 are rotatably connected to each other through the connecting shaft 106, and a spring piece 103 is connected between the handle 101 and the handle 2 102, and both sides of the spring piece 103 are fixedly connected to the handle 101 and the handle 2 102 respectively;

[0024] When the pliers body assembly 1 is in operation, handle 1 101 and handle 2 102 are used to move them closer to each other, thereby driving the ends of handle 1 101 and handle 2 102 away from each other, thereby driving the ends of pliers head 1 105 and pliers head 2 104 closer to each other, thereby enabling related orthopedic operations to be performed.

[0025] The protective component 2 includes a protective shell 201, and the upper end of the protective shell 201 is detachably connected to a top cover 204. The protective shell 201 and the top cover 204 are both made of stainless steel. The protective shell 201 and the top cover 204 are connected by screws. Both ends of the top cover 204 and the protective shell 201 are provided with a front sealing strip cover 202 and a rear sealing strip cover 203. The front sealing strip cover 202 and the rear sealing strip cover 203 are tightly fitted with the surface of the caliper body assembly 1. The front sealing strip cover 202 is provided with a receiving groove 1 2021, and the rear sealing strip cover 203 is provided with a receiving groove 2031.
