Elastic internal clavicle fixator

Abstract

The invention discloses an elastic internal clavicle fixator composed of a clavicle distal steel plate body, an elastic arm with an upswept angle, and elastic plates attached to the steel plate body, with the clavicle distal steel plate body and the elastic arm integrally formed; when the elastic arm is inserted to a position slightly to the lower rear of acromion, clavicle is downwardly reduced by pressing down the fixator, whether to restore the clavicle length through a slide relief hole or not is determined according to shortening condition of a fracture segment, a distal facture bone piece is fixed through clavicle distal locking holes, and a proximal fracture end is firmly fixed through proximal large locking holes. In this way, stress of the fracture end is transferred to the acromion through the elastic arm, reduction loss can be prevented, micro motion function of the acromioclavicular joint can also be retained, the elastic plates can control the rise of the distal end of clavicle and can also self-deform to absorb stress or disperse the stress to the whole elastic arm, stress concentration is prevented, and elastic fixation is finally achieved.

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...

Problems solved by technology

[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.
