Abstract

The invention relates to a bone pinning device for fracture fixation. The device comprises a gun body, a pin discharging box, a gun bolt, a pin discharging mechanism, a gun body fixing seat, a linkage shaft, a trigger, a connecting shaft seat and a handle, wherein the gun body is of a rectangular structure; a gun bolt chute is formed in the gun body; the gun bolt is glidingly connected with the gun bolt chute; the pin discharging mechanism is positioned into the gun bolt and fixedly connected with the gun bolt; the pin discharging box is arranged at the front end of the gun body; the gun body fixing seat is fixedly connected with the rear end of the gun body; the linkage shaft passes through the gun body fixing seat, and the middle part of the linkage shaft is in rotating connection with the gun body through a bearing; a trigger is fixedly connected with the linkage shaft; linkage shaft seats are fixed to two sides of the linkage shaft; the handle is fixedly connected with the gun body fixing seat. With the adoption of the device, fracture pieces can be quickly and efficiently fixed; particularly the fracture recovering pins with different size are provided for fixing small facture pieces; therefore, the broken fracture pieces can be effectively fixed; the fracture healing rate is increased; the use is convenient; the broken fracture pieces can be quickly and stably fixed; the healing rate can be increased.

Description

technical field [0001] The invention relates to a bone nail device for fracture fixation, which belongs to the field of medical instruments. Background technique [0002] In the process of fracture reduction, there is currently no effective reduction and fixation device for the reduction of a small number of fracture fragments. Fracture patients often cause fracture nonunion due to bone defects, causing serious losses to individuals and the country. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a nail and bone device for fracture fixation, which overcomes the difficulty in resetting a small part of the fracture in the prior art, and there is no effective reset and fixation device, which often causes fractures in patients with fractures due to bone defects. A defect that is difficult not to heal. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follo...
