Abstract

The application provides a special meniscal retractor for knee arthroscopy, including: a first adapter, a second adapter assembly, a support plate, a sliding plate, a locking device, an ankle fixation sleeve, a telescopic mechanism and an elastic band, and the second adapter The device assembly includes a second adapter and several angle positioning support rods pivotally connected to the second adapter. A socket is respectively provided on the second adapter and each angle positioning support rod; one end of the support plate is pivotally connected to the second On a coupler, the inserting plate pivotally connected to the other end of the support plate is connected with the corresponding jack to make the support plate tilt to different angles; the sliding plate is arranged on the supporting plate transversely; the locking device is used to connect the sliding plate to the supporting plate The boards are connected together; the ankle fixing sleeve is rotatably arranged on the sliding board; the telescoping mechanism is connected between the ankle fixing sleeve and the sliding board; the elastic band is connected at both ends of the ankle fixing sleeve. This application enables reliable eversion of the menisci with the leg straightened or the knee bent.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a special meniscus retractor for knee arthroscopy. Background technique [0002] The meniscus is located on the medial and lateral articular surfaces of the tibial plateau. It is prone to damage and tear during strong physical labor or sports. These tears may even be caused without obvious trauma. Meniscus injury is a common disease in orthopedic clinics. It is usually treated by arthroscopic joint repair, shaping or resection. The key to the operation is to fully expose the meniscus. Initially, clinically, two assistants applied force on the thigh and calf in opposite directions. This method not only wastes manpower, but also occupies the operating space of the operator, affecting the operator's work efficiency. [0003] Chinese patent CN201710280849.2 discloses an auxiliary retractor for medial meniscus exposure body surface. One end of the fixed shaft is connected with connecting...
