Flexible fixing plate for acromioclavicular joint

Abstract

The invention relates to a flexible fixing plate for the acromioclavicular joint and belongs to the technical field of implantation materials in human bodies. The flexible fixing plate for the acromioclavicular joint is composed of an arc-shaped upper main board, an arc-shaped lower main board and an elastic deformation structure. The arc-shaped upper main board and the arc-shaped lower main board are connected and fixed through the two ends of the elastic deformation structure, and an upper main board fixing hole and a lower main board fixing hole are manufactured in the arc-shaped upper main board and the arc-shaped lower main board. Through the elastic deformation structure and the two arc-shaped main boards, the acromioclavicular joint can be elastically fixed, the original anatomical correspondence of the acromioclavicular joint can be restored to the maximum extent, the flexible fixing plate is firm and reliable in fixation, easy, convenient and accurate to install and position and good in treatment and healing effect, and postoperative restoration loss can be avoided. The flexible fixing plate for the acromioclavicular joint solves the problems that because the compressive stress of an existing hook steel plate structure on the acromion and the clavicle is too large, pain, the pressure swelling feeling, hook disengagement and fear of movement can be caused to a patient easily; the common problems that surgical restoration is not ideal, subacromial tissue is injured, and the treatment effect is seriously affected because an elastic micro movement fixing plate for the acromioclavicular joint is not high enough in elasticity are solved.

Description

technical field [0001] The invention relates to an elastic fixation plate for acromioclavicular joints, which belongs to the technical field of implants in human body. Background technique [0002] For acromioclavicular joint injuries with large displacement, surgical treatment is generally performed. The current surgical methods for the treatment of acromioclavicular joint dislocation generally include: Kirschner wire tension band surgery, coracoclavicular ligament repair and reconstruction, arthroscopic reconstruction techniques, and hook plate fixation techniques. Because the hook plate fixation technique only needs to insert the pointed hook head of the hook plate under the scapula, and then fix the plate body with screws, the operation is relatively convenient. It has developed rapidly in recent years and has gradually become the first choice for surgical treatment of various acromioclavicular joint dislocations. treatment method. However, hook plate fixation has the ...

Problems solved by technology

[0005] The object of the present invention is to provide a 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, is fixed firmly, is easy and accurate to install and locate; does not damage the articular surface, and is subject to individual bone anatomy. The impact of the difference is small, the stress is dispersed, and it basically matches the physiological activity of the acromioclavicular joint of the human body; it can solve the problem of excessive pressure stress on the acromion and clavicle due to the existing hook plate structure, or excessive local force on the acromion, causing pain and swelling in patients , uncomfortable; and can not control the gap size and range of motion of the acromioclavicular joint, damage the subacromial soft tissue or bone tissue, high postoperative recurrence rate or postoperative reduction loss rate of the acromioclavicular joint elastic fixation plate
