Embodiment

[0030] Such as Figure 1-7 As shown, a high-precision knee joint meniscus cutting device includes a device housing 1 and a downward-pressing polygonal rod 2. The lower end of the downward-pressing polygonal rod 2 is fixedly installed with a support assembly 3 through a crescent plate gasket 301, and the lower end of the downward-pressing polygonal rod 2 is fixed. It is fixedly installed in the center of the upper surface of the crescent plate gasket 301, and the upper part of the upper part of the multi-angle rod 2 is pressed down to be provided with a device shell 1. One side of the upper surface of the device shell 1 is fixedly installed with a fixed assembly 7 through two flipping rod mounting seats 702. One side of the upper surface of the device shell 1 is fixedly installed with two turning rod mounting seats 702 respectively, and the bottom end of the polygonal rod 2 is pressed down and is located on the upper surface of the crescent plate gasket 301. The movable sleeve i...

Abstract

The invention relates to the technical field of knee joint surgery, in particular to a high-precision knee joint meniscus cutting device which comprises a device shell and a downward-pressing polygonal rod, a supporting assembly is fixedly installed at the lower end of the downward-pressing polygonal rod through a crescent plate gasket, and the lower end of the downward-pressing polygonal rod is fixedly installed in the center of the upper surface of the crescent plate gasket; the upper end of the downward-pressing polygonal rod is movably sleeved with the device shell, a fixing assembly is fixedly installed on one side of the upper surface of the device shell through two overturning rod installation bases, and the two overturning rod installation bases are fixedly installed on one side of the upper surface of the device shell; and a crescent plate positioning sleeve is movably sleeved on the bottom end of the downward-pressing polygonal rod and located on the upper surface of the crescent plate gasket, and a cutting limiting plate is fixedly installed in the middle of the pressing polygonal rod body. By using the cutting device provided by the invention, it can be guaranteed that the cut meniscus is regular, the cartilage below the meniscus can be effectively protected, and the accurate size is provided for follow-up transplantation.

Description

technical field [0001] The invention relates to the technical field of knee joint surgery, in particular to a high-precision knee joint meniscus cutting device. Background technique [0002] The meniscus is an important part of the knee joint, and its existence and integrity are crucial to ensure the normal function of the knee joint. With the development of competitive sports in the direction of higher, faster and stronger, the incidence of refractory meniscal injuries is also increasing significantly. Meniscectomy as a traditional surgical approach has been proven unable to guarantee the long-term therapeutic effect of refractory meniscus injury. [0003] So meniscus transplantation has become a new solution to meniscus injury. The purpose of meniscus transplantation can be summarized as follows: relieve the pain after meniscectomy, prevent the degeneration of articular cartilage and subchondral bone after meniscectomy, prevent or reduce the risk of osteoarthritis and re...
