Abstract

The invention provides a meniscus cutter, which relates to the technical field of medical equipment. The meniscus cutter comprises a handheld bracket, a connecting rod, a cutter head and a first adjusting knob, wherein the connecting rod and the handheld bracket are in rotary connection, and the cutter head is arranged at the end part of the connecting rod assembly; and the first adjusting knob sleeves the connecting rod for driving the connecting rod to rotate relative to the handheld bracket. According to the meniscus cutter provided in the invention, rotation of the cutter head is realizedthrough rotating the first adjusting knob, a doctor does not need to frequently change meniscus tools with different angles, the visual field is ensured to be clear, the rotating process is convenient, the operation time is effectively shortened and the probability of secondary injuries is reduced.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a meniscus cutter. Background technique [0002] Meniscus injury of the knee joint is a common and frequently-occurring disease in clinic. The purpose of meniscus surgery is to relieve symptoms and maximize function. The easiest way to relieve symptoms is partial meniscus resection, which is the simplest and most effective, and is the most widely used. The preserved meniscus tissue can still maintain the physiological functions of stability, transfer and absorption of load, and obtain better curative effects. [0003] When cutting curved parts, doctors using traditional meniscus cutting tools need to frequently replace meniscus tools with different angles, which can not guarantee a clear vision, prolong the operation time, and increase the probability of secondary injury. [0004] Therefore, how to provide a meniscus cutter capable of realizing angle adjustment is one of the t...
