Technical Field
The utility model relates to the technical field of medical devices, especially, relate to a hollow anchor system of sewing up.
Background
After dislocation of the acromioclavicular joint, the coracoid and acromioclavicular ligaments break. After reduction of the dislocation a secure fixation is required to bring the broken ligaments closer together and achieve healing. There are two ways to fix: rigid fixation and elastic fixation. Because the acromioclavicular joint belongs to the micro joint, the rigid fixation limits the movement of the joint, so the elastic fixation is commonly used clinically at present. Elastic fixation is the fixation between the clavicle and the coracoid process using non-absorbable sutures. The anchor of the suture anchor with the thread is directly screwed into the coracoid process, so that the potential risk of damaging the medial vascular nerve when the Ethibond 5 suture bypasses the bottom of the coracoid process can be avoided, and the use is convenient. However, both have a common problem in that the knot is easily loosened when the knot is tied above the clavicle, and once the knot is loosened, the operation fails. Therefore, the use of the Endobutton-loop steel plate for surgical treatment is clinically appeared, and the treatment effect is still in clinical observation. And while the Endobutton-loop steel plate system adds strength to the fixation, surgery also adds difficulty and complexity to the procedure.
In order to make the operation simple, convenient and reliable, the prior art adopts suture to anchor coracoid process. However, the anchor is solid and is difficult to remove after being screwed into the coracoid process. Once the suture anchor with thread has problems of improper location, infection or rejection, it is difficult to handle. At the same time, nuclear magnetic examinations are also limited.
