Long bone fracture repositioning device

Abstract

The invention discloses a long bone fracture repositioning device, which comprises a proximal end support frame, a distal end support frame, quick drawing extension rods, steel needle fixing clamps and steel needles, wherein the quick drawing extension rods are connected between the proximal end support frame and the distal end support frame, the steel needle fixing clamps are connected to the proximal end support frame and the distal end support frame, the steel needles are clamped by the steel needle fixing clamps, the proximal end support frame and the distal end support frame are same in structure and respectively comprise a transverse chute type repositioning slide plate and two fixed gliding hole plates which are connected to the chute type repositioning slide plate, one surface of each chute type repositioning slide plate is provided with a transverse guide sliding chute, a transverse guide long hole is formed between the bottom of the guide sliding chute and the other surface of the chute type repositioning slide plate, the fixed gliding hole plates are provided with holes for connecting the steel needle fixing clamps, the fixed gliding hole plates are further provided with positioning bulges which are matched with the guide sliding chutes and can slide along the guide sliding chutes. The long bone fracture repositioning device disclosed by the invention is simple in structure, the minimally invasive idea is enhanced, the excellent rate of repositioning is improved, and requirements of fracture repositioning and various malformation correcting can be met to the maximum extent.

Description

technical field

[0001] The invention relates to a fracture reducer, in particular to a fracture reducer for long bone fracture reduction. Background technique

[0002] Fracture reduction is the basic operation of external fixation to treat fractures. With the improvement of the equipment and the improvement of the technical concept, the various adjustment functions and operating procedures of the fracture reducer have made new progress, which not only facilitates the operation, but also satisfies the requirements of fracture reduction and various deformity correction to the greatest extent. Some devices have increased fracture reduction and deformity correction functions; some have improved operating procedures, such as implementing the restoration and correction functions step by step. However, no matter how perfect the restoration function is, the external fixator is only an auxiliary tool. In most cases, it depends on the doctor's wisdom and dexterous surgery to complete...
