A high-stretch reducer for calcaneal fracture

Abstract

The invention belongs to the technical field of orthopedic medical instruments and discloses a calcaneal fracture height traction reduction apparatus used for calcaneal fracture height traction reduction. The technical scheme includes that a metatarsus fixing steel needle, a scaphoid bone fixing steel needle and a calcaneus fixing steel needle horizontally penetrates the metatarsus, the scaphoid bone and cuboid bone and the calcaneus respectively. Front ends of two upper fixing connection rods are connected with two ends of the metatarsus fixing steel needle while rear ends are connected withtwo ends of the scaphoid bone fixing steel needle; front ends of two upper fixing connection adjustable pull rods are connected with two ends of the scaphoid bone fixing steel needle respectively while rear ends are connected with two ends of the calcaneus fixing steel needle; front ends of two lower fixing connection adjustable pull rods are connected with two ends of the metatarsus fixing steelneedle respectively while rear ends are connected with two ends of the calcaneus fixing steel needle. The calcaneal fracture height traction reduction apparatus has advantages of simple structure, convenience in use, reliability in reduction and less trauma, and calcaneus height and calcaneus introversion force line can be recovered at the same time.

Description

technical field [0001] The invention relates to a device for pulling and reducing the fracture height of the calcaneus, belonging to the technical field of orthopedic medical devices. Background technique [0002] Calcaneal fractures are the most common tarsal fractures, of which intra-articular fractures account for about 75%. Calcaneal fractures are mostly caused by falls, falls or traffic accidents. All intra-articular fractures are caused by axial stress. Stress leads to increased width and decreased height of the calcaneus (smaller Bohler's angle), which, if not managed properly, can lead to poor functional recovery of the foot. At present, the surgical schemes for calcaneal fractures are mainly divided into two types: minimally invasive closed reduction and internal fixation and open reduction and internal fixation. No matter which technical scheme is adopted, the width and height of the calcaneus must be restored (to restore the normal Bohler's angle). ), correct the...

Problems solved by technology

However, it is not suitable to hold the above methods for reduction, and the reduction force is relatively small, and it cannot be effectively temporarily fixed after reduction. The operator often has to use bare hands to maintain the reduction, but it is often difficult to achieve a satisfactory result due to insufficient strength. reset effect
