Abstract

The invention provides a multifunctional telescopic cutting scalpel for the discoid meniscus operation under a knee arthroscope. The multifunctional telescopic cutting scalpel comprises a main sheath, an auxiliary sheath, a blade and a blade moving mechanism. The main sheath is provided with threaded holes, a button moving groove, a scaleplate scale, locking grooves and inclined lines. The auxiliary sheath is provided with threaded holes, a scaleplate scale and inclined lines. The blade is provided with a blade scale and a blade installing hole. The blade moving mechanism comprises a blade installing groove, an elastic steel sheet, a button, a locking pin and a blade holder. When reaching a tear portion from an inlet of the arthroscope, the cutting scalpel can effectively prevent damage to normal tissue such as peripheral vessels and nerves, thigh bone cartilage, tibial plateau cartilage and anterior and posterior cruciate ligaments; the multifunctional telescopic cutting scalpel can be used for measuring a fracture wound accurately, thereby guaranteeing accurate cutting and maintaining and protecting normal meniscus tissue to the greatest extent; the cutting scalpel is simple and convenient to operate, and the inclined lines can increase friction force to prevent the scalpel from falling off from hands; the locking device can prevent tissue damage caused by fault in gear change, thereby improving safety.

Description

technical field [0001] The invention relates to a multifunctional telescopic cutting knife for surgery, in particular to a multifunctional telescopic cutting knife for discoid meniscus surgery under knee arthroscopy. Background technique [0002] The rupture of the lateral discoid meniscus of the knee joint is very common. For patients with rupture of the lateral discoid meniscus, doctors usually cut directly with a scalpel under the arthroscope, and then enter from the entrance of the arthroscope to the tearing meniscus, and cut the meniscus. During the process, it is extremely easy to damage the normal femoral condyle cartilage, tibial plateau cartilage, and surrounding blood vessels and nerves. Ordinary surgical blades have a fixed length, and it is difficult to adapt to the different thicknesses of different parts of the meniscus; human cartilage cannot be regenerated, and damage to important blood vessels and nerves in the knee joint will bring great pain to the patient...
