Joint motion device for postoperative rehabilitation of children

Abstract

The invention discloses a joint motion device for postoperative rehabilitation of children. The device comprises an elbow joint motion part and a driving part. The elbow joint motion part comprises athird strip-shaped arc plate, first fixed plates, a second strip-shaped arc plate, second fixed plates, a gear, a strip-shaped piston barrel, a piston, a first piston rod, a rack, an annular limitingblock and a reset spring. The first fixed plates are arranged on two sides of one end of the third strip-shaped arc plate respectively. The second fixed plates are arranged on two sides of one end ofthe second strip-shaped arc plate respectively. The two second fixed plates are located on the inner sides of the two first fixed plates. The joint motion device for postoperative rehabilitation of children drives an elbow joint to carry out bending training while exercising fingers and a wrist joint; and because a child patient can adjust the bending angle by himself or herself, the problem thatwhen a parent or a medical worker assists the child patient in carrying out bending training on the elbow joint, because the parent or the medical worker cannot control the force well, the child patient feels pain during training, and then has lower motivation is solved.

Description

technical field [0001] The invention relates to the technical field of joint movement devices, in particular to a joint movement device for postoperative rehabilitation of children. Background technique [0002] For children with elbow dislocation and elbow fractures (including supracondylar humerus fractures, humeral lateral condyle fractures, radial neck fractures, and proximal ulna fractures), after removal of plaster external fixation or steel pin internal fixation, it is necessary to perform activity exercises as soon as possible, otherwise it will Elbow extension, flexion, and rotation functions are limited, and severe cases will cause sequelae, which will affect the function of the elbow joint. [0003] Therefore, it is very important to help children perform elbow joint bending training at an early stage; early training is mainly for parents and medical staff to assist children with elbow joint bending, but because parents and medical staff cannot master the strength...

Problems solved by technology

[0003] Therefore, it is very important to help children perform elbow joint bending training at an early stage; early training is mainly for parents and medical staff to assist children with elbow joint bending, but because parents and medical staff cannot master the strength when assisting children with elbow joint bending training , causing pain in children during training, and children generally have fear of pain, poor self-control ability, poor coordination reduce enthusiasm for training, and it is easy to cause secondary fractures or local congestion and edema due to intense activities, and myositis ossificans Formation, joint movement disorder in the later stage, and because of the dislocation of the elbow joint and the plaster of the arm after the fracture of the elbow, the fingers and wrists do not move frequently, so it is necessary to train the wrist and fingers during joint training. Therefore, a training program is designed to address these problems. Joint activity device for postoperative rehabilitation of children
