Acromioclavicular joint reduction guide

Abstract

The invention discloses a reset guider for an acromioclavicular joint and relates to the technical field of medical instruments. The reset guider comprises a push part and a hook part; the push part is used for pressing collarbones; the hook part is used for hooking the coronoid; the hook part is of a hollow structure and is formed by the rod portion and the hook portion; the hook part also comprises a fine adjustment structure which is used for enabling the push part to move far away from or close to the hook part relative to the rod portion. According to the reset guider for the acromioclavicular joint, the two problems of acromioclavicular joint reset and coracoclavicular ligament repair are solved simultaneously; a coracoclavicular ligament repair channel is established when the acromioclavicular joint is reset and accordingly the operation steps are simplified; lead wires are fed into the hollow reset guider for the acromioclavicular joint and accordingly the acromioclavicular joint can be completely reset, meanwhile the risk of damage to upper limb blood vessel nerves which are close to the coronoid is prevented, the safety of the operation is ensured, and the suffered second operation pain and economic burden of a patient is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and relates to a reduction guide for acromioclavicular joints. Background technique [0002] Dislocation of the acromioclavicular joint is common in clinical practice, and it is often accompanied by rupture of the coracoclavicular ligament leading to upward displacement of the clavicle or the proximal end of the clavicle. Because these methods do not damage the fundamental damage of the acromioclavicular joint dislocation, that is, the coracoclavicular ligament is repaired or reconstructed, or the acromioclavicular joint cannot be accurately reset during the operation, postoperative subluxation often occurs. The failure rate of the acromioclavicular joint is high; in addition, the acromioclavicular joint has rotation and other movements, and the fixation method using screws does not meet the physiological needs of people. Other internal fixation operations require a second operati...

Problems solved by technology

[0002] Dislocation of the acromioclavicular joint is common in clinical practice, and it is often accompanied by rupture of the coracoclavicular ligament leading to upward displacement of the clavicle or the proximal end of the clavicle. Because these methods do not damage the fundamental damage of the acromioclavicular joint dislocation, that is, the coracoclavicular ligament is repaired or reconstructed, or the acromioclavicular joint cannot be accurately reset during the operation, postoperative subluxation often occurs. The failure rate of the acromioclavicular joint is high; in addition, the acromioclavicular joint has rotation and other movements, and the fixation method using screws does not meet the physiological needs of people. Other internal fixation operations require a second operation to remove the internal fixation material, causing pain and economic burden to the patient.
