In order to achieve the above object, the present invention provides the following technical solutions: the utility model provides a rongeur for under minimal access channel, includes fixed pincers body, handle and shell fragment, fixed pincers body bottom is equipped with the handle, install the shell fragment between the handle of handle and fixed pincers body, still including installing the activity pincers body at fixed pincers body top.

Preferably, a strip-shaped groove is formed in one side of the top of the movable clamp body, and the movable clamp body penetrates through the strip-shaped groove through a screw to be connected with the fixed clamp body.

Preferably, the right end of the top of the fixed caliper body is provided with a notch groove, and the right end of the movable caliper body is attached to the notch groove.

Preferably, a through hole is formed in the position, corresponding to the notch groove, of the fixed caliper body, and a button is arranged in the through hole.

Preferably, the right end of the button is provided with a push head, and the push head is fixedly connected with the movable pliers body.

Preferably, a spring is installed at the left end of the button, and the right end of the spring is connected with the outer wall of the fixed caliper body.

The utility model has the advantages that: the binding clip of fixed binding clip tip backward displacement and activity binding clip tip interlock, take out behind the broken bone, the handle is loosened to the finger, press the button with the thumb, the button promotes to push away the head and the activity binding clip carries out the displacement, activity binding clip and fixed binding clip body carry out the rotation part through the screw this moment, then wash inside blood stain and the broken bone of remaining to the binding clip, loosen the button, the spring resets the button, the activity binding clip body that the button is connected simultaneously also resets, it is once to clear up not need to sting, the operation is swift, and the work efficiency is improved.
