A microsurgical robot for inner meniscus of knee joint

Abstract

The invention discloses a micro-surgical robot for the inner meniscus of the knee joint, which belongs to the field of medical equipment and comprises a base. The top wall of the base is provided with a lifting mechanism. There are three rotating mechanisms on the wall, the top of the main shaft is fixed with an arc-shaped support plate, the lifting mechanism includes two supporting seats and two lifting frames, and each lifting frame includes two connecting rods connected in rotation , the top and bottom ends of the two lifting frames are respectively installed in rotation with the support base, and the lifting frames are threaded through a two-way threaded rod. One end of the two-way threaded rod is equipped with a knob, and the end of the knob is installed with a Ropes: The robot in this solution can be conveniently and stably placed in the joint through the setting of various structures, and can clearly and accurately grasp the internal conditions of the joint, which is convenient for medical personnel to operate inside the joint through the robot, and improves the convenience and accuracy of the operation.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a micro-surgical robot for the inner meniscus of the knee joint. Background technique [0002] The menisci are two crescent-shaped fibrocartilaginous discs located between the femoral and tibial surfaces on the medial and lateral sides of the knee joint. The main components are water, collagen and proteoglycans, which have the ability to resist tension, compression and shear stress . With the improvement of social living standards, people's sports methods are becoming more and more diversified, resulting in an increase in the incidence of knee meniscus injuries year by year. [0003] At present, meniscus tears are usually treated by knee arthroscopic surgery. Doctors will take total resection, partial resection, suture repair and other treatment methods for meniscus tears according to the type of meniscus tear. Arthroscopy is a kind of endoscopic technology. A lens is...

AI Technical Summary

Problems solved by technology

[0006] 2. During the use of arthroscopy, the doctor needs to constantly adjust the position of the patient's lower limbs to obtain a certain space, resulting in a long operation time and the risk of damage to the knee ligament

[0007] 3. Arthroscopic equipment has great difficulties in observing the meniscus in special parts and operating the equipment. Due to the limited operating space, the treatment of the posterior angle of the medial meniscus has always been a difficult problem in sports medicine
