Clamp-type acromioclavicular joint embolia reduction guiding system

Abstract

The invention discloses a clamp-type acromioclavicular joint embolia guiding system. The clamp-type acromioclavicular joint embolia guiding system comprises a coracoid side clamp, a clavicle side clamp and a handle, wherein a spherical base is arranged at the clamp tip of the coracoid side clamp; a conical tip protrusion is formed at the position, in contact with the coracoid side, on the surface of the spherical base; a rotatable hollow guiding device is arranged at the clamp tip of the clavicle side clamp. The clamp-type acromioclavicular joint embolia guiding system has the advantages that (1) the embolia of an acromioclavicular joint and central linear drilling between the coracoid and the clavicle are completed at a time; (2) drilling guidance is accurate, and the fracture of the coracoid and the clavicle is avoided; (3) by virtue of the accurate drilling guidance and the spherical design of the coracoid clamping end, the injury to important vascular nerves on the inner side of the coracoid during an operation is avoided; (4) the spacing between the clavicle and the coracoid is accurately measured in an outer measurement mode by virtue of a graduated scale at the far clamping end, so that the appropriate length of a loop needed by embolia fixing is selected; (5) the instrumentation is simple, convenient and safe, the operation wound is minimized, and a true minimally invasive effect is achieved.

Description

technical field [0001] The invention belongs to medical equipment, and more specifically relates to a pincer-type acromioclavicular joint reduction guide system applied in the field of orthopedic surgery. Background technique [0002] Acromioclavicular joint dislocation is a common shoulder injury in clinical practice, accounting for about 12% of shoulder injuries and 4.4-5.98% of bone and joint dislocations in the whole body, of which 43.5% are seen in young people in their 20s. Dislocation of the acromioclavicular joint is often caused by indirect violence when the outside of the shoulder touches the ground or the arm of the affected limb supports the ground. Mainly cause shoulder pain, aggravated pain when the upper limb of the affected side is raised or abducted, local palpable tenderness or deformity of the acromioclavicular joint, swelling of the lateral end of the acromion, rebounding piano key sign when pushed down, X-ray film mainly Manifested as an enlarged coraco...

AI Technical Summary

Problems solved by technology

The surgical field needs to be fully exposed during the operation, and the length of the skin incision is usually 8-10 cm; repeated drilling or inaccurate positioning of the coracoid process and the clavicle tunnel often lead to coracoid process and clavicle fractures; repeated drilling until the tunnel is too large can easily damage the Endobutton plate. Sliding out of the tunnel; because there are important structures such as the brachial plexus and axillary artery inside the coracoid process, the operation on the side of the coracoid process may damage these important adjacent structures; it is difficult to measure the size of the loop selection, or the acromioclavicular joint is not Anatomical reduction will lead to too large loop size selection and postoperative subluxation, which will reduce the postoperative effect

Although it has been reported that arthroscopic intraoperative monitoring can be used to improve surgical accuracy and reduce intraoperative complications, but this method has stricter requirements on the surgeon and is difficult to popularize
