Abstract

The invention discloses a hand external skeleton rehabilitation system based on memory alloy driving. The hand external skeleton rehabilitation system comprises a glove (1), a palm plate (2), a power source (3) and a finger linkage system. The palm plate (2), the power source (3) and the finger linkage system are all fixed on the glove (1). The finger linkage system is connected with the palm plate (2). A memory alloy spring is used as a driving device, the structure is simple and light, the five fingers can move independently, and the flexibility is high. A four-bar mechanism is used as an external skeleton transmission mechanism, and the hand external skeleton rehabilitation system is easy to install and maintain and can be suitable for patients with different finger lengths. The external skeleton is different from a traditional driven rehabilitation external skeleton. Surface electromyogram signals are used as control signals of the hand external skeleton, rehabilitation movement is controlled by the patients themselves, and a curative effect is promoted. The hand external skeleton rehabilitation system is convenient, easy to use, safe, effective and low in cost and has wide application prospects.

Description

technical field [0001] The invention relates to a human body motion assisting device, in particular to an exoskeleton rehabilitation system driven by a memory alloy, which is suitable for patients with hand dysfunction. Background technique [0002] The hand is one of the most complex and important organs of the human body, but it is also a very vulnerable part. Hand injuries often have a long recovery period, and the recovery of fine motor functions is often unsatisfactory, which seriously affects the quality of life of patients. How to promote the recovery of hand function after injury has become very important. [0003] In 1960, Canadian orthopedic surgeon Robert Salter proposed Continuous Passive Motion (CPM). Use external force to drive the affected limb to do long-term and full-range passive activities, so as to prevent the stiffness of the patient's joints and promote blood circulation in the affected limb. Fluid circulation to speed up recovery. CPM therapy has b...
