Description

Technical Field

[0001] The utility model relates to the technical field of separation scissors, in particular to a pair of double-edged meniscus separation scissors. Background Art

[0002] The meniscus is a layer of fibrous cartilage located between the femur and tibia of the knee joint. It is divided into the inner and outer menisci, which are half-moon-shaped and are necessary structures of the knee joint. They play an important role in maintaining joint stability, buffering movement shock, and protecting articular cartilage. The location and special structure of the meniscus make it easy to be damaged or worn under the action of external forces. Since the blood supply of the meniscus is poor, it is not easy to heal on its own. The damaged or worn meniscus not only cannot assume the original function, but also damages other structures of the knee joint, causing traumatic arthritis. Therefore, if the diagnosis of meniscus damage or wear is clear, surgical treatment should be performed as soon as possible;

[0003] The overall structure of the existing double-edged meniscus separation scissors is relatively fixed, and the cutting end of the scissors is usually sharp. When the doctor takes the scissors and uses them, the doctor's hand may accidentally touch the sewing part, thereby causing injury to the doctor's hand and affecting the operation. In addition, when the existing double-edged meniscus separation scissors are stopped in the middle of the operation, an assistant is generally required to take them or the scissors are directly placed on the operating table, which may easily cause the cutting part of the scissors to be contaminated. Therefore, we propose a double-edged meniscus separation scissors. Utility Model Content
