An auxiliary device and method for resetting a displaced articular disc

Abstract

The invention provides an auxiliary device and method for resetting a displaced articular disc, which includes a clip bar, a telescopic rod, a retractor bar, a movable sleeve, a fixed sleeve, a movable rod and a button, and a telescopic rod is fixed on the right end of the clip bar , the fixed sleeve is fixed on the bottom of the telescopic rod, the fixed sleeve is equipped with a movable sleeve, the left end of the movable sleeve is equipped with a retractor strip, the movable sleeve is equipped with a movable rod, and the right end of the movable rod is equipped with a button. The incision is supported by distraction, which solves the problem that the auxiliary device is not fully functional in the original articular disc reduction operation. The invention has few consumables, low cost, complete auxiliary functions and good operation effect.

Description

technical field [0001] The invention relates to an auxiliary device and method for resetting a displaced articular disc, belonging to the technical field of oral and maxillofacial surgery. Background technique [0002] At present, many patients with condyle fractures or articular disc diseases need to undergo reduction and anchoring of the articular disc. The commonly used clinical method is to fully free the ligament of the articular disc, so that the articular disc covers the cartilage surface above the condyle. In order to prevent the disc from being displaced again, two anchors need to be implanted on the surface of the condyle, and the sutures used to suture the disc are tied above the anchors. In this way, with the help of the antagonism of the anchor nails, the articular disc will not be displaced again, but will remain in the reset position. [0003] In the prior art, the anchor nail is made of metal, which will have more or less influence on the patient's subseque...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the anchor nail is made of metal, which will have more or less influence on the patient's subsequent CT or MRI examination.

In addition, the anchor nail itself is a foreign implant relative to the body. Although the material compatibility is very good, for some patients with greater psychological pressure, they often require the removal of the implant in the body, which limits the Application of Metal Anchors

With the advancement of materials, absorbable anchors have appeared clinically, but this material itself is gradually degraded and absorbed in the body, and the long-term effect on the reduction and fixation of the articular disc has not yet been verified.

At the same time, the existing devices for assisting surgery in the reduction operation of the articular disc are not comprehensive enough, and multiple medical staff are usually required to assist during the operation. In view of the above situation, there is a need for an auxiliary device and method for resetting the displaced articular disc. to solve the above problems
