AI Technical Summary

Technical Problem

Among the existing treatment methods for distal radius fractures, splint fixation is not stable enough and cannot effectively support patients to carry out standardized and efficient rehabilitation training, resulting in a prolonged recovery period and easily causing complications such as secondary displacement of fracture ends, limb shortening and joint stiffness.

Method used

A functional exercise device was designed, comprising an arc-shaped plate, a worm gear transmission mechanism, and an airbag pneumatic linkage. The worm gear transmission enables standardized wrist rotation rehabilitation training, while the airbag drives finger joint flexion and extension movements. Combined with a dial to monitor the exercise angle, the device ensures the safety and stability of the rehabilitation process.

Benefits of technology

It significantly shortens the fracture healing period, reduces the risk of secondary injury, improves the safety and effectiveness of rehabilitation training, promotes the functional recovery of the affected limb, and prevents muscle atrophy and joint stiffness.

Abstract

The invention discloses a functional exercise device for distal radius fracture, and relates to the technical field of orthopedic rehabilitation medical instruments, the functional exercise device comprises arc plates symmetrically arranged in an arc shape, and the middles of the two arc plates are rotatably connected through a hinge piece; and the functional exercise assembly is fixedly installed at the ends, away from the wrist, of the two arc plates, and the functional exercise assembly comprises two fixing boxes. According to the functional exercise device for the distal radius fracture, rehabilitation training can be achieved through a meshing transmission structure of a worm gear, a worm and a bevel gear, finger joints can be driven to do soft and uniform flexion and extension activities through air pressure linkage of air bags on the two sides, and synchronous integrated exercise of wrist joints and the finger joints is achieved; in the exercising process, local blood circulation can be effectively accelerated, soft tissue swelling can be eliminated, muscular atrophy and joint stiffness can be prevented, meanwhile, the osteoporosis risk is reduced, the fracture healing period is remarkably shortened, and the movement function of the affected limb is efficiently promoted to be comprehensively recovered.
