A combined resetter for calcaneal fracture

Abstract

The invention provides a calcaneal fracture combined repositor, and belongs to the technical field of orthopedic medical devices. The calcaneal fracture combined repository is used for repositioning acalcaneal fracture. The technical scheme is that a left tong rod and a right tong rod are placed crosswise, and the tong heads and tong handles of the left tong rod and right tong rod are laterally opposite to each other, shaft holes of the left tong rod and right tong rod are vertically opposite to each other, the upper portion of a repositioning combined shaft is a vertical shaft rod, the lowerportions of the repositioning combined shaft are two vertical plates parallelly opposite to each other, the two vertical plates are respectively provided with opposite horizontal shaft holes, the shaft holes of the left tong rod and right tong rod sleeve the shaft rod of the upper portion of the repositioning combined shaft, the shaft holes and the shaft rod cooperatively rotate, horizontal shafts are arranged in the horizontal shaft holes in the lower portions of the repositioning combined shaft, the front end of a lower push rod is a push plate, the back portion of the lower push rod is a pressing rod, a shaft hole is formed between the push plate and the pressing rod, the horizontal shafts of the lower portions of the repositioning combined shaft are in rotatable and cooperative connection with a shaft of the lower push rod. The calcaneal fracture combined repositor has the advantages that reposition orthotics can be performed by enlarging the calcaneus width and reducing the calcaneus height, the operating difficulty is reduced, the operation time is shortened, and the effect of the reposition orthotics is improved.

Description

technical field [0001] The invention relates to a device for resetting a calcaneus fracture during an operation, belonging to the technical field of orthopedic medical devices. Background technique [0002] Calcaneal fracture is the most common tarsal fracture, 85% to 90% of which are intra-articular fractures, and the articular surface of the calcaneus is mostly involved. Calcaneal fractures are mostly caused by violence in the axial direction of the calcaneus, and falls from heights and car accidents are common injury factors. Many patients have fractures involving the subtalar articular surface, and the unevenness of the articular surface and the changes of Boiller angle and Gissane angle can lead to the occurrence of traumatic arthritis. At the same time, the deformed state of the calcaneus can lead to a series of problems, such as tibiotalar joint impingement, fibular collateral ligament impingement syndrome, and heel lift weakness. Due to the complex anatomical struc...

AI Technical Summary

Problems solved by technology

[0003] When using closed reduction and internal fixation, since the articular surface often collapses after calcaneus fractures, the width of the calcaneus becomes larger, and at the same time, the calcaneus is highly compressed, and correction needs to be performed at the same time during the reduction of calcaneus fractures, so closed reduction requires more This kind of instrument is clamped from both sides and bottom of the calcaneus, which requires the cooperation of multiple people, and the reset time is long and it is difficult to achieve satisfactory results

So far, this situation has not been effectively improved, which restricts the implementation and extensive development of closed reduction treatment of calcaneal fractures, and urgently needs to be resolved
