Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fracture threading reduction, in particular to a minimally invasive reduction threading kit for dislocation of acromioclavicular joint. BACKGROUND

[0002] The acromioclavicular joint is composed of the joint surface of the acromion of the scapula and the joint surface of the acromion of the clavicle. The joint capsule is relatively loose and attached to the periphery of the joint surface, and there is a coracoclavicular ligament connecting the coracoid process of the scapula and the lower clavicle for reinforcement. The acromioclavicular joint is a plane joint and can make micro-motion in all directions, but the movement amplitude cannot be too large, otherwise it is easy to dislocate; when the acromioclavicular joint is completely dislocated and external fixation cannot maintain its alignment, surgical open reduction and internal fixation are usually used.

[0003] The reduction methods include manual reduction and surgical open reduction. Manual reduction is mainly for fractures without obvious displacement or stability. It is generally recommended that patients try to keep their chests straight, fully open their shoulder joints, and then fix them with an 8-shaped bandage on their backs. For fractures with displacement or comminution, surgical treatment is generally recommended. A 10cm incision is made at the fracture site, then the skin fascia is sequentially incised, the fracture end is exposed, temporary fixation is performed with a Kirschner wire, and then the wound is closed after fixation with a steel plate screw.

[0004] The Kirschner wire and steel wire tension band were applied early, and the operation was simple, with small trauma and low cost, but it was easy to loosen or break, and the Kirschner wire was displaced; the Kirschner wire passed through and damaged the joint surface, causing traumatic arthritis; the micro-motion of the acromioclavicular joint was limited, causing pain in the acromioclavicular joint. The efficacy of Kirschner wire tension band in the treatment of acromioclavicular joint dislocation was reviewed, and the patient satisfaction rate was not more than 50%. Therefore, Kirschner wire tension band is rarely used in the treatment of acromioclavicular joint dislocation in clinical practice at present.

[0005] At present, surgical open reduction is basically chosen for acromioclavicular joint dislocation. During reduction, the position of the coracoid process of the scapula and the clavicle needs to be stable and can be locked to each other. At this time, the reduction thread needs to be looped around the coracoid process of the scapula and the clavicle below and bound together to form a relative fixed positional relationship, and then the subsequent surgical steps can be performed after the stability is ensured.

[0006] At present, it is difficult to thread the gap between the coracoid process of the scapula and the clavicle below. The reduction of the coracoid process of the scapula and the clavicle needs to be looped around the coracoid process of the scapula below and wound around the clavicle above to form a whole, and then looped around the clavicle above, and then the coracoid process of the scapula and the clavicle are pulled and restrained to be reduced, and the positions of the two bones are relatively fixed, so as to complete the reduction operation.

[0007] Because the coracoid process of the scapula is embedded protruding along the sagittal axis of the human body, and the clavicle is transversely grown in the same direction as the frontal axis, the coracoid process of the scapula and the clavicle are crossed in different directions, and it is troublesome to fix and thread, and it is very difficult to fix the depth position of the conventional curved hook surgical needle, to thread the needle around the coracoid process of the scapula and the clavicle, resulting in a long operation time. The operation may thread the needle between the coracoid process of the scapula and the clavicle in the human body, and it is also difficult to accurately position, and when the position is not correct, the curved needle needs to be pulled out and reinserted between the bones to position and pull the line to bind the coracoid process of the scapula and the clavicle, so the needle needs to be repeatedly inserted and pulled, even if the position is accurate outside the skin, but the needle needs to be inserted into the human body, and the needle inserted into the muscle will be deflected and twisted, resulting in difficult positioning and long operation time.

[0008] Based on this, the present application designs a minimally invasive reduction overline kit for dislocation of acromioclavicular joint to solve the above problems. SUMMARY

[0009] The purpose of the present application is to provide a minimally invasive reduction overline kit for dislocation of acromioclavicular joint, which can position the coracoid process of the scapula and the clavicle, and hold more stably by using the threading forceps, and after aligning outside the skin, the threading forceps can stablly insert into the bone to be positioned according to the rotation path, so as to accurately and quickly thread the bone to be reduced, because the holding is convenient and the stress is stable, it is not easy to be disturbed by the muscle and ligament, so that the device can stably and conveniently position and thread the bone.
