Air-actuated flexible finger motion rehabilitation equipment

Abstract

The invention discloses a flexible pneumatic finger sport recover, which contains flexible pneumatic bending knuckle, wherein the flexible pneumatic bending knuckle is composed of end lid, rubber pipe and metal yarn in the pipe wall in the rubber pipe; the metal yarn is spiral steel yarn, which concludes restraint steel yarn in one lateral pipe wall of rubber pipe; the restraint steel yarn wraps each spiral steel yarn; two ends of rubber pipe connect end lid tightly; the through-hole is opened on the end lid; three flexible pneumatic bending knuckles constitute knuckle group with flexible rack on the bottom; the restraint belt connects flexible rack on the finger tightly; the high-pressure gas pipe interconnects through-hole of each end lid of each flexible pneumatic bending knuckle.

Description

(1) Technical field [0001] The invention belongs to a finger motion rehabilitation device, in particular to a finger motion rehabilitation device based on pneumatic technology, which is suitable for passive motion training rehabilitation of human fingers after surgery. (2) Background technology [0002] Due to the complex anatomical structure of the hand, problems such as joint ankylosis, tendon adhesion, and muscle atrophy often remain after finger trauma. After flexor tendon injury, different degrees of adhesions often occur, hindering the sliding of the tendon and affecting finger function. Therefore, early and careful rehabilitation care is required after surgical trauma to reduce the occurrence of the above-mentioned complications. Before the present invention was made, the traditional method was to perform tendon adhesion release surgery, that is, to carry out secondary surgery after finger trauma. Carry out early rehabilitation training for tendon repair patients, s...

Problems solved by technology

Before the present invention was made, the traditional method was to perform tendon adhesion release surgery, that is, to carry out secondary surgery after finger trauma. Carry out early rehabilitation training for tendon repair patients, such as the utility model patent "Multifunctional Hand Rehabilitation Instrument" with the patent number 00237727.6 discloses a multifunctional hand and arm rehabilitation device suitable for various ages and various parts, but it is not enough The advantages are: 1. The device uses springs and finger cots as the main functional components, that is, the patient's fingers actively move, the spring is pulled through the finger cots, and the elastic force of the springs is used to perform auxiliary movements. It belongs to the active rehabilitation device for patients and is not suitable for Early passive rehabilitation training; 2. The device cannot train the three joints of a single finger separately; 3. The device is a mechanical structure. Although it has multiple adjustment mechanisms, its adaptability to the shape of the hand and fingers is still limited
