Problems solved by technology

[0004] The current fixers for the treatment of long bone fractures are all unilateral, and the fixation pins are inserted into the long bone from one side for fixation. This fixation is not stable enough, and it is prone to deviation, so that the fracture cannot be healed.

Abstract

The invention relates to medical instruments, in particular to a bone needle fixing device for long bone fracture treatment. The bone needle fixing device comprises an X-direction fixing screw rod, aY-direction fixing screw rod, a Z-direction fixing screw rod, an L-shaped adjusting screw rod, a bone needle fixing frame, a first fixed bone needle and a second fixed bone needle. According to the device, an adjustable support is used for adjusting the bone needle to carry out fracture external fixation, the fracture face can be stably fixed with injury of several needle holes without performingan operation under most conditions and can be adjusted, the bone needle fixing device is light, easy to adjust and operate, wide in application range, economical, convenient to use, good in treatmenteffect and easy for a patient to accept, and the aim of fixing a fracture with microtrauma.

Description

technical field [0001] The invention relates to medical equipment, in particular to a bone needle fixation device for treating long bone fractures. Background technique [0002] Long bones are mainly found in the extremities and are long tubular. A long bone fracture is a complete or partial break in the continuity of the bone structure. It is more common in children and the elderly, and it also occurs from time to time in young and middle-aged people. Patients often have a fracture at one site, and a few have multiple fractures. After timely and appropriate treatment, most patients can restore their original function. [0003] After the fracture is reduced, it is prone to redisplacement due to instability, so different methods should be used to fix it in a satisfactory position and make it heal gradually. Commonly used fixation methods are: small splints, plaster bandages, external fixation brackets, traction brake fixation, etc. These fixation methods are called extern...
