Miniature surgical robot for meniscus in knee joint

Abstract

The invention discloses a miniature surgical robot for a meniscus in a knee joint, and belongs to the field of medical equipment. The miniature surgical robot comprises a base, wherein a lifting mechanism is arranged on the top wall of the base, a main shaft is arranged on the upper side of the lifting mechanism, three rotating mechanisms are arranged on the side wall of the main shaft, and an arc-shaped supporting plate is fixed at the top end of the main shaft. The lifting mechanism comprises two supporting bases and two lifting frames. Each lifting frame comprises two connecting rods whichare rotatably connected, wherein the top ends and the bottom ends of the two lifting frames are rotatably installed on the supporting bases correspondingly, the lifting frames are installed in a threaded mode through two-way threaded rods, a rotary knob is installed at one end of each two-way threaded rod, and a rope is mounted at one end of the rotary knob. According to the scheme, the robot canbe conveniently and stably placed in the joint through the arrangement of all the structures, the internal condition of the joint can be clearly and accurately mastered, medical staff can convenientlyconduct an operation in the joint through the robot, and the convenience and accuracy of the operation are improved.

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
