Abstract

The invention discloses a calcaneal traction restorer which comprises a sliding rod, a sleeve, symmetrical arms, a pull rod, a supporting rod and positioning holes, wherein one end of the sliding rod is connected with one symmetrical arm to which one end of the pull rod is connected movably, the other end of the sliding rod is sleeved in the sleeve, the middle part of the pull rod is connected with the supporting rod moveably, the other end of the supporting rod is connected with one end of the sleeve, the other end of the sleeve is connected with the other symmetrical arm, and the outer endsof the symmetrical arms are provided with the positioning holes or grooves. The calcaneal traction restorer has the advantages of convenient operation, accurate positioning, good treatment effect, low cost and little discomfort of patients and can be used for position maintenance after traction reduction and fracture reduction in a calcaneal fracture operation for facilitating the traction in thecalcaneal fracture operation, providing stable traction force, and improving the fracture reduction accuracy and the operation treatment effect. The calcaneal traction restorer can stably maintain positions after traction and fracture reduction, reduce iatrogenic injury and lighten the treatment burden of patients and is an ideal special fracture reduction medical appliance.

Description

technical field [0001] The invention relates to a medical device, more specifically, a calcaneal traction resetter used for the reduction, positioning, fixation and guidance of bone scars such as fractures and fractures in intra-articular fractures of the calcaneus. Background technique [0002] Intra-articular fractures of the calcaneus usually affect the posterior articular surface of the calcaneus, causing displacement and deformation of the fracture of the calcaneus, especially the subtalar posterior articular surface, and often require surgical treatment. During the operation, in order to restore the morphological structure of the calcaneus and the smoothness of the posterior articular surface, it is necessary to perform traction on the shortened calcaneus body, restore the shape of the calcaneus, reset the inverted and collapsed posterior articular surface, and maintain traction for necessary fixation. How to maintain traction during surgery? How to stabilize the frac...
