Abstract

The invention discloses a meniscus suturing instrument in the field of medical equipment. The instrument comprises a cannula, a needle pushing tube is connected to one end of the cannula, and a handleis connected to the end, away from the cannula, of the needle pushing tube; a needle pushing rod is slidingly connected into the cannula, a needle pushing handle is slidingly connected into the needle pushing tube and connected with the needle pushing rod, a suture needle is arranged in the cannula at the outer side of the end, away from the needle pushing handle, of the needle pushing rod and comprises two syringe needles, and a suture is connected between the two syringe needles. According to the meniscus suturing instrument, through design of the double syringe needles of the suture needleand design of the cannula, the needle pushing rod and the needle pushing handle, suturing can be completed merely through one-time puncture in the meniscus suturing surgery, and in the suturing process, vice-damage caused to the meniscus by repeated puncture on the meniscus with the suture needle cannot be caused.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a meniscus stapler. Background technique [0002] The meniscus is a layer of fibrocartilage located between the femur and tibia of the knee joint. It is a necessary structure of the knee joint and plays an important role in maintaining joint function. Meniscus injury is a common sports injury in orthopedics, which can lead to pain during walking or exercise and joint mobility impairment, seriously affecting the quality of life of patients. Meniscus injuries are mostly caused by torsional external force, resulting in meniscus tear, which can occur in the anterior horn, posterior horn and body of the meniscus. Due to the poor blood supply of the meniscus, it is not easy to heal itself after the injury. At the same time, the torn meniscus will damage other structures of the knee joint, resulting in traumatic arthritis. The conventional treatment method is arthroscopic meniscus sut...
