Abstract

The invention provides a meniscus retractor special for a knee arthroscope. The meniscus retractor comprises a first bearing device, a second bearing device assembly, a supporting plate, a sliding plate, a locking device, an ankle fixing sleeve, a telescopic mechanism and elastic bands, wherein the second bearing device assembly comprises a second bearing device and a plurality of angle positioning supporting rods pivoted to the second bearing device, and the second bearing device and each angle positioning supporting rod are each provided with an inserting hole; one end of the supporting plate is pivoted to the first bearing device, and an inserting plate pivoted to the other end of the supporting plate is connected with the corresponding inserting hole in a matched mode so that the supporting plate can incline by different angles; the sliding plate is transversely arranged on the supporting plate; the locking device is used for connecting the sliding plate and the supporting plate together; the ankle fixing sleeve is rotationally arranged on the sliding plate; the telescopic mechanism is connected between the ankle fixing sleeve and the sliding plate; and the elastic bands are connected to the two ends of the ankle fixing sleeve. By means of the meniscus retractor, a meniscus can be reliably turned outwards under the condition that legs are straightened or knees are 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...
