Background

Fracture refers to the continuous complete or partial breakdown of bone structure. The comminuted fracture is more in fracture patients, and because the bone blocks of the patients are broken into a plurality of pieces, the reduction and the fixation of the fracture parts during the treatment have great difficulty. The resetting forceps in the prior art are generally fixedly connected with a guider, when the resetting forceps are used, a bone block is clamped by the resetting forceps for resetting, then a guide pin penetrates through the guider to drill a hole in the bone block, and then the position of the guider is moved to expose the drilled hole and then the screw is screwed for fixing. This approach suffers from the following disadvantages:

one is poor fixation accuracy. When the screw screwing fixing operation is carried out after the drilling is finished, the clamping position of the reset pliers needs to be moved due to the influence of the position of the guider on the screw screwing operation, and the screw screwing fixing operation can be carried out on the drilled hole only after the guider and the drilled hole of the bone block are staggered to expose the drilled hole. In the mode, the clamping and resetting stability between the bone blocks can be influenced in the process of moving the resetting forceps, so that the bone blocks are loosened and dislocated, the accuracy of subsequent screw fixing operation is influenced, even the normal operation of screwing the screws is influenced, and the fracture patient is easily subjected to secondary injury.
