Description

Meniscus suture hollow needle

Technical Field

The utility model belongs to the technical field of the medical treatment is sewed up, concretely relates to meniscus is sewed up hollow needle.

Background

The meniscus is two crescent shaped fibrocartilage, located at the medial and lateral articular surfaces of the tibial plateau. The cross section of the bone grafting plate is triangular, the outer part is thick, the inner part is thin, the upper surface is slightly concave so as to be matched with the femoral condyle, and the lower surface is flat and connected with the tibial plateau. The structure just leads the femoral condyle to form a deeper depression on the tibial plateau, thereby increasing the stability of the spherical femoral condyle and the tibial plateau; the anterior and posterior ends of the meniscus are attached to the medial non-articular surface of the tibial plateau, anterior and posterior to the intercondylar eminence, which may also be referred to as the anterior and posterior horn of the meniscus.

Meniscus injury is a joint injury of meniscus tear, is caused by twisting external force, causes severe pain of knee joint, automatic straightening failure, joint swelling and tenderness at knee joint gaps, and is an important basis for judging meniscus injury. Sometimes, the joint can not move like being locked, and the phenomena of 'interlocking' and 'bounce' appear, which seriously hinders the flexion and extension movement of the knee joint.

Meniscus suture is the most ideal operation mode of treatment meniscus damage at present, and the suture needle has the tape thread function, has two kinds of suture modes of sewing up entirely and sewing up from inside to outside, but these two kinds of suture modes can not sew up meniscus anterior horn and somatic part anterior part all, and the suture needle is mostly stainless steel, and when sending the needle hard, the stylolite rubs with the suture needle, probably leads to the stylolite to break.
