A knee flexible auxiliary rehabilitation device

Abstract

The invention belongs to the field of medical apparatuses and instruments and particularly relates to a flexible knee-joint rehabilitation assisting device. The flexible knee-joint rehabilitation assisting device comprises a base plate, wherein a semi-circular ring is fixedly connected to the upper surface of the base plate, a connecting block is fixedly connected to the upper surface of the baseplate, a first cavity is formed in the connecting block, a piston is slidingly connected to the inner wall of a first cavity, a second cavity is formed in the piston, a limiting mechanism is slidinglyconnected to the inner wall of the second cavity, a connecting rod is fixedly connected to the upper surface of the piston, the top of the connecting rod penetrates through the top of the first cavity and is rotatably connected with a rotary rod through a first rolling bearing, a slide block is fixedly connected to the rod wall of the rotary rod, a connecting plate is slidingly connected to the side wall of the slide block, the side wall of the connecting plate is provided with a slide groove matched with the slide block, a first arc-shaped block is hinged to the top of the connecting plate,and the side wall of the first arc-shaped block is fixedly connected with an arc-shaped plate. The flexible knee-joint rehabilitation assisting device is smaller in size and convenient to use and improves the rehabilitation effect of a patient, and the safety and practicability of the flexible knee-joint rehabilitation assisting device are also improved.

Description

Technical field [0001] The invention belongs to the technical field of medical equipment and relates to a knee joint flexible auxiliary rehabilitation device. Background technique [0002] The knee joint is composed of the lower end of the femur, the upper end of the tibia and the patella. It is the largest and most complex part of the human body. It belongs to the trochlear joint. The synovial layer of the knee joint is the widest and most complicated of the whole body joints. It is attached to the periphery of the articular surface of the bones of the joint. , Covering all structures in the joint except the articular cartilage and meniscus, the synovial membrane is above the upper edge of the patella, and it protrudes upward to form a suprapatellar capsule with a depth of about 5cm between the quadriceps tendon and the lower part of the femoral body. [0003] The existing knee joint flexible assisted rehabilitation device is generally a movable support frame. The patient supports...
