Description
Technical Field
The utility model relates to a suture instrument technical field, in particular to improvement meniscus suture instrument.
Background
Meniscal injuries are clinically common sports medicine diseases, and the current gold standard for treatment is arthroscopic minimally invasive treatment. For patients under 45 years of age with damaged red areas of the meniscus, meniscal suturing is preferred to preserve meniscus structure.
Half moon plate stitching currently has three main techniques: 1. the full-internal suture adopts a typical instrument which is a fast-fix full-internal suture needle with good brightness, and is mainly suitable for suturing meniscus body parts and rear angle injuries; 2. the outside-in suture method is the 18# lumbar puncture needle which is most commonly used clinically and is suitable for suturing the anterior angle and the body of the meniscus; 3. the inside-out suturing method needs special instruments and arc-shaped baffles, is suitable for the damage of the body part and the posterior angle of the meniscus and is relatively applied to the minimum clinically at present. The three suturing methods are similar to the principle of suturing meniscus with instruments, and the damaged meniscus is sutured with tissues such as lateral ligament, joint capsule and the like, so as to promote healing. However, this procedure has significant clinical drawbacks in treating injuries to the lateral meniscal body, because the posterior aspect of the lateral meniscal body is free at the outer edge and not connected to the lateral collateral ligament, and the popliteal tendon passes through the outer edge, which has some mobility relationship. When the outer meniscus body part is sutured in a treatment mode, the meniscus is sutured together with the popliteal tendon or the outer collateral ligament and the joint capsule by adopting a previous suturing mode, the original free structure of the meniscus is not met, the meniscus is connected with tissues such as the popliteal tendon, the outer collateral ligament and the joint capsule after suturing, and obvious dragging discomfort can be generated when a patient moves after surgery.
SUMMERY OF THE UTILITY MODEL
In view of the above, there is a need for an improved meniscal stapler to solve the problem that the meniscus is sutured with the popliteal tendon or the collateral ligament or the joint capsule, which causes significant discomfort during postoperative activities of patients.
