Elastic clavicle elastic inner fixation device

Abstract

The invention discloses an elastic clavicle inner fixation device. The elastic clavicle inner fixation device is jointly composed of a steel plate main body, an elastic arm and elastic sheets, whereinthe elastic sheets are attached to a steel plate, after the hooking end of the elastic arm is inserted to the portion below the acromion, by pressing the near end of the steel plate main body, the clavicle can be restored downwards, then according to cripetura situations of a fracture segment, whether to restore the length of the clavicle by sliding a pressure-reducing hole or not is decided, bone blocks at the far folding end and the near folding end are locked and fixed to be an integral whole through far-end locking holes and near-end locking holes respectively, in this way, stress of thefolding ends is transferred to the acromion through the elastic arm, and meanwhile, the elastic sheets can play effects of controlling lifting of the far end of the clavicle and absorbing stress through the shape change of itself or dispersing the stress to the whole segment of the elastic arm, stress concentration is prevented, thus finally elastic fixation is achieved, and various shortcomings of a traditional clavicle hook steel plate can also be made up for.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an elastic clavicle internal fixator. Background technique [0002] Fracture and dislocation of the distal clavicle is relatively common in clinical practice. Among them, there are difficulties in the treatment of acromial fractures. Acromial impingement pain, limited shoulder joint mobility, broken hook, broken plate, and subacromial bone wear are common in the treatment of clavicle hook plate. However, when using the distal clavicle locking plate for treatment, there are common disadvantages such as unstable fixation of the distal small bone fragment, shortening of the folded end after surgery, and inability to perform early functional exercises; there are many fixation methods for acromioclavicular joint dislocation, such as using the Hook plate, loop plate, anchor system, coracoid screw, and Kirschner wire tension band, etc. Among them, the clavicular hook plate is the most...

[0002] Fracture and dislocation of the distal clavicle is relatively common in clinical practice. Among them, there are difficulties in the treatment of acromial fractures. Acromial impingement pain, limited shoulder joint mobility, broken hook, broken plate, and subacromial bone wear are common in the treatment of clavicle hook plate. However, when using the distal clavicle locking plate for treatment, there are common disadvantages such as unstable fixation of the distal small bone fragment, shortening of the folded end after surgery, and inability to perform early functional exercises; there are many fixation methods for acromioclavicular joint dislocation, such as using the Hook plate, loop plate, anchor system, coracoid screw, and Kirschner wire tension band, etc. Among them, the clavicular hook plate is the most commonly used because of its low technical difficulty and firm fixation, but there are still similar complications. However, other treatment methods have problems such as relatively difficult operation, easy to cause secondary injury, complicated operation process, long learning curve, loss of micro-motion function of acromioclavicular joint and failure of fixation, etc.
