Fracture repositor for radius

Abstract

The invention discloses a fracture repositor for radius, comprising a support frame which is provided with an upper platform and a lower platform. The upper platform is provided with an upper support guide rail and the upper support guide rail is provided with an upper mobile platform. The upper mobile platform is provided with a palm connecting fixed plate. The upper mobile platform is connected with an upper translation driving mechanism. The upper platform is further provided with a fixed platform. The lower platform is provided with a lower guide rail. The lower guide rail is provided with a lower mobile platform. The lower mobile platform is connected with a lower translation driving mechanism. The lower mobile platform is provided with a lifting connecting mechanism. The fracture repositor for radius compensates the deficiency that current traction device cannot automatically realize manual traction completely and realizes automatic control of traction and restoration treatment.

Description

technical field [0001] The invention belongs to a fracture reduction device, in particular to a radius fracture reduction device. Background technique [0002] Radius fracture is the most common fracture, especially the fracture of distal radius accounts for about 10% of systemic fractures. The common treatment methods for distal radius fractures are manual traction reduction and external fixation with splints. Manual traction reduction mainly relies on medical staff to implement manual traction, and the patient's treatment posture is not fixed, so the work intensity is high and the patient suffers. The inventor once owned the patent 200920087037.7, trying to solve the problem of manual reset through this technology. This patent realizes traction reduction by a movable bracket and a fixed bracket, and a wrist jacking device is set on the fixed bracket simultaneously. When performing reduction, by fixing the palm, the elbow joint goes around the arm rod for traction, and t...

AI Technical Summary

Problems solved by technology

When performing reduction, by fixing the palm, the elbow joint goes around the arm rod for traction, and the traction direction is along the proximal direction of the radius, that is, the traction is performed behind the forearm; this kind of traction elbow joint must go around the arm rod, otherwise it cannot be implemented Traction, so the palm and elbow joint must be fixed at the same time, it is difficult to adjust the patient's posture; at the same time, the wrist jacking device can only perform upward lifting adjustments, and cannot perform downward pulling adjustments, which limits the operation. The non-adjustable part of the wrist jacking also limits the scope of application of the surgery, so the operability of the above-mentioned devices is poor and it is difficult to be widely used
