Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a suturing instrument for temporomandibular joint disc anchoring operation.
Background
The temporomandibular joint is one of the most complex joints of the human body, and because the posterior ligament of the joint is weaker than the muscle attachment strength of the anterior zone, the joint disc is more easily damaged, which is manifested by various types of displacement of the joint disc, and the incidence rate of the displacement accounts for the head of temporomandibular joint diseases. Since the first proposed open temporomandibular disc anchorage procedure in 2001 as taught by Larry Wolford, the procedure was gradually approved by experts in the same group and improved in practice. However, the operation is complicated in local anatomical structure of the temporomandibular joint, the operation space is narrow, a beginner is difficult to master the core operation suture skill, and most temporomandibular joint discs cannot recover to normal positions even if the operation is completed. This prompted us to think again whether the procedure of the procedure could be optimized.
In the existing open temporomandibular joint disc anchoring operation, a common needle holder and a suture needle are usually adopted for completion, and due to the narrow operable space of a joint area, the needle is difficult to be stably held, the suture needle is easy to rotate and cannot be sutured to an ideal position, so that the operation can be repeated for a long time to cause pain to patients and operators.
