Calcaneal fracture electric traction poking reduction device

Abstract

The invention discloses a calcaneal fracture electric traction poking reduction device comprising a first kirschner wire, a first kirschner wire kit, a driving mechanism, a second kirschner wire, a second kirschner wire kit and a third kirschner wire. The first kirschner wire kit includes a first fixed end and an inner sliding end. The first fixed end is hollow inside, and the hollow position is fitted with the first kirschner wire. The driving mechanism comprises a driving rod assembly and a power assembly. The driving rod assembly comprises an external sliding end, a retaining ring, a rack end and a poking fixed end. The poking reduction device can better achieve traction and poking reduction of the fractured calcaneus.

Description

technical field [0001] The invention relates to a resetter for traction and prying of calcaneus fractures. Background technique [0002] Calcaneal fracture is a common fracture symptom in clinical practice, and calcaneus shortening and lateral articular surface collapse are the most common. At present, the treatment method is mainly surgical treatment. During the operation, Kirschner wires are used to cross the calcaneus to correct the shortening of the calcaneus, and then the assistants draw it by hand; the collapse of the lateral articular surface is pried with Kirschner wires. Stable, and intraoperative C-arm fluoroscopy requires the operator to be exposed to radiation. Once let go, all efforts will be in vain and re-operation is required. Repeated traction and prying increase trauma and operation time. Contents of the invention [0003] The purpose of the present invention is to provide an electric traction pry resetter for calcaneus fractures, which can avoid exposur...
