Fixator combining mesoscapula part, acromion part and distal clavicle part

Abstract

A fixator combining a mesoscapula part, an acromion part and a distal clavicle part is made of memory alloy, the shape of the fixator is a whole fracture-setting steel plate, and the fixator is divided into four parts including the mesoscapula part, the acromion part, a joint bridging part and the distal clavicle part and is an inner fixing medial instrument suitable for the fracture of the mesoscapula area, the acromion area and the distal clavicle with or without acromioclavicular dislocation. The shape of the fixator is designed according to the layout and the physiological anatomy shape of the acromion area, the mesoscapula area and the distal clavicle, and can connect and stereoscopically fix the acromion area, the mesoscapula area and the distal clavicle together. The fixator is good in elasticity and strength and can be processed in a bent, twisted and sheared mode freely according to the fixation need of a fracture operation. In addition, the fixator is convenient to shape and install, external fixation is not needed after the operation, early function exercise of the shoulder joint is facilitated, and postoperative ankylosis is prevented. By means of the fixator, the curative effect is improved, complications are reduced, a complex operation is simplified, operation risks are reduced, and the fixator is worth popularization.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an internal joint fixator specially used for fractures of the acromion area, scapular spine, and distal clavicle with or without dislocation of the acromioclavicular joint. Background technique [0002] With the development of the economy and the development of transportation, construction and other industries, scapula fractures have become increasingly common in recent years, accounting for 3% to 5% of shoulder fractures, close to 1% of systemic fractures, and coracoid process fractures accounted for 3% to 13% of scapula fractures. The key to the treatment of scapula fractures is to restore the anatomical shape and mechanical stability as much as possible. Early functional exercise. In the past, for severe comminuted scapula fractures, because there was no exact and effective fixation method, non-surgical treatment was often used, which easily caused sequelae such as ...

AI Technical Summary

Problems solved by technology

However, there are disadvantages: the structure of the instrument is too simple, and it cannot be locked with other parts close to the fracture site of the scapula. Complex and cumbersome, not very practical, not many real applications

Due to the irregular position and complex anatomical structure, the surgical technique is difficult and risky, and the quality of surgical instruments and surgical methods can directly affect the treatment effect

The current traditional surgical methods and instruments can solve some problems, but the disadvantage is that the treatment effect is not ideal, and some new instruments that have appeared are not practical, so they are difficult to promote and use

[0010] At present, there is a lack of anatomical internal fixation devices that match the scapula, which increases the difficulty of the operation and directly affects the treatment effect
