Acromioclavicular joint elastic micro-motion fixing plate

Abstract

The invention relates to an acromioclavicular joint elastic micro-motion fixing plate and belongs to the technical field of human body implants. The acromioclavicular joint elastic micro-motion fixing plate is composed of a micro-arc-shaped main plate, two U-shaped structures, a left twisting plate and a right twisting plate. The left twisting plate and the right twisting plate are symmetrically manufactured at one end of the micro-arc-shaped main plate, the left twisting plate and the right twisting plate are connected with the micro-arc-shaped main plate through the U-shaped structures, and the U-shaped structures can conduct flexible adjustment in the horizontal plane and the vertical plane. The micro-arc-shaped main plate, the left twisting plate and the right twisting plate are provided with fixing holes respectively. The micro-arc-shaped main plate, the two U-shaped structures, the left twisting plate and the right twisting plate fixedly support the three ends of a shoulder blade, control the gap size and the moving range of an acromioclavicular joint, and are suitable for micro motion of the acromioclavicular joint in each direction, firm in fixing, and easy, convenient and accurate to install and position. The problems that an existing hook steel plate structure makes pressure stress of an acromion and the clavicle too large and cannot control the gap size and the moving range of the acromioclavicular joint, operation restoration is prone to being unsatisfactory, a hook slides down from the acromion, and the treatment effect is seriously impacted are solved.

Description

technical field [0001] The invention relates to an elastic micro-movement fixing plate for acromioclavicular joint, 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 fixat...

Problems solved by technology

[0003] The purpose 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 firm in fixation, easy and accurate in installation and positioning; 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 human acromioclavicular joint. It can solve the problem that the existing hook plate structure causes excessive pressure stress on the acromion and clavicle, causing pain, swelling, and discomfort to the patient; and it cannot control the acromioclavicular joint. The size of the joint gap and the range of motion, damage to the subacromial soft tissue or bone tissue, postoperative recurrence rate or the high rate of reduction and loss after removal of the internal fixation problem.
