AI Technical Summary

Problems solved by technology

At present, the only external fixation bracket for calcaneus fracture can not control and accurately reduce the fracture and completely restore the arch height and calcaneus angle. Therefore, it is not widely used clinically, and it cannot treat flat feet, and its versatility and extensiveness of treatment are poor.

Abstract

The invention discloses a movable and adjustable calcaneus reduction external fixator which comprises two fixing frames arranged on the two sides of the foot respectively. Each fixing frame comprises three long telescopic shafts and two short telescopic shafts, wherein the three long telescopic shafts form a triangular external support, the two short telescopic shafts and one long telescopic shaft form a triangular internal support, and the positions where the long telescopic shafts are connected or the positions where the short telescopic shafts are connected with the short telescopic shafts are provided with needle guards which are perpendicular to the plane of the triangular external support and are used for fixing kirschner wires. The movable and adjustable calcaneus reduction external fixator has the advantages of being small in size, flexible in adjustment, reliable in fixation and good in generality and universality for treating fractures and enabling a patient to do joint functional exercises in the early period of postoperation.

Description

technical field [0001] The present invention relates to a medical device, in particular to a movable adjustable calcaneal external fixation with small size, flexible adjustment, reliable fixation, good versatility and extensiveness for treating fractures device. Background technique [0002] Calcaneal fractures are increasingly common in trauma orthopedics, and open reduction has become the main treatment method adopted by hospitals at all levels. Although some doctors use steel needle prying reduction and external fixator fixation treatment, open reduction is used because of uncontrollable and accurate fracture reduction, complete restoration of arch height and calcaneus angle. The complications of open reduction of calcaneal fractures are many and complex, and the most common complications include tension vesicles, periosteal space syndrome, wound dehiscence and infection, vascular and nerve injury, tendon injury, calcaneal arthritis, Achilles tendon contracture, Side im...
