Acromioclavicular elastic fixing plate

Abstract

The invention relates to an acromioclavicular elastic fixing plate and belongs to the technical field of implants in a human body. The fixing plate comprises an upper fixing plate body, a lower fixing plate body and an elastic deformation structure. The upper fixing plate body and the lower fixing plate body are fixedly connected through the two ends of the elastic deformation structure. Upper fixing plate fixing holes and lower fixing plate fixing holes are manufactured in the upper fixing plate body and the lower fixing plate body respectively. The elastic deformation structure, the upper fixing plate body and the lower fixing plate body are used for elastically fixing an acromioclavicular joint, the acromioclavicular joint can restore an original anatomical corresponding relationship to the largest extent, fixation is firm, installation and positioning are easy and accurate, pain of patients is greatly reduced, and the healing effect is good. The problems that due to an existing hook plate structure, compressive stress on acromion and clavicle is too large, the effect of fixing exo-clavicular comminuted fracture and acromioclavicular joint dislocation is poor, patients feel pain, have compression feeling and are unhooked and afraid of activities, an elasticity attenuation capacity of an elastic structure is poor, the long-term effect is not ideal, and the treatment effect is severely affected are solved.

Description

technical field [0001] The invention relates to a shoulder lock elastic fixing plate, which belongs to the technical field of implants in human body. Background technique [0002] For fractures of the outer end of the clavicle and / or dislocations of the acromioclavicular joint with large displacement, surgical treatment is generally required. At present, the surgical methods for treating fractures of the outer end of the clavicle are mostly fixation with clavicular bone plate or clavicle hook plate. However, when the fracture of the outer end of the clavicle is comminuted and the outer end of the clavicle is fixed with screws through the clavicle bone plate, the fracture of the outer end of the clavicle is often comminuted. Heavy screw fixation is not stable, which affects the fixation effect, and serious complications such as screw loosening and fracture redisplacement occur; when hook plate fixation is used to treat the outer end of the clavicle fracture, sometimes the out...

Problems solved by technology

[0006] The purpose of the present invention is to address the deficiencies of the above-mentioned prior art, to provide a kind of micro-motion that can adapt to all directions of the acromioclavicular joint, can control the size of the gap and the range of motion of the acromioclavicular joint, and can be installed and fixed firmly, and the positioning is simple and accurate; The articular surface is less affected by individual bone anatomical differences, with good stress dispersion, strong elastic attenuation ability, and strong matching with the anatomical structure of the human clavicle and acromion; to solve the problem that the existing clavicle bone plate is not firmly fixed at the outer end of the clavicle, or The elastic plate’s anti-elastic attenuation ability is not good, or the structure of the hook plate makes the acromion and clavicle compressive stress too large, the hook end is unstable, or the local force of the acromion is too large, causing pain, swelling, and discomfort of the patient; and it cannot be controlled The acromioclavicular elastic fixation plate is suitable for problems such as the gap size and range of motion of the acromioclavicular joint, damage to subacromial soft tissue or bone tissue, postoperative recurrence rate or high rate of reduction and loss after internal fixation removal.
