Wrist joint movement function evaluation and rehabilitation robot

Abstract

The invention discloses a wrist joint motion function evaluation and rehabilitation robot, which realizes all motion forms of a wrist joint according to a human wrist joint skeleton structure and canbe a structure of adjusting equipment for patients with different forearm lengths and different wrist lengths. An elbow position adjusting mechanism is fixedly connected with a support, and a wrist joint ring rotating mechanism, a wrist joint ring rotating axis adjusting mechanism, an ulnar and radial deviation driving mechanism, a metacarpal dorsiflexion driving mechanism and a tail end grabbingmechanism are connected to the end of the elbow position adjusting mechanism. A grab handle of the tail end grab mechanism can be separated from equipment, a gyroscope is arranged in the grab handle,and when the grab handle is separated from the equipment, the movement range of the wrist joint of a patient can be measured through the grab handle; when the grab handle is spliced on the equipment,the human-computer interaction acting force between the patient and the equipment can be measured by utilizing the grab handle. The robot structure is suitable for different patients, evaluates the motion function states of the patients, and achieves personalized and quantitative rehabilitation evaluation and training of wrist joint motion function evaluation and rehabilitation.

Description

technical field [0001] The invention relates to a robot and a medical equipment technology with an evaluation function, in particular to a medical equipment with functions of wrist joint movement rehabilitation and evaluation. Background technique [0002] The incidence of stroke is very high in the elderly population, and 80% to 90% of the surviving patients often suffer from hemiplegic sequelae. It is worth noting that in people's daily life and work, the functions of the upper limbs and hands play an important role. Many stroke patients have dysfunction of the upper limbs and hands after the onset, mainly manifested as finger flexion, adduction, wrist The joint flexes and deviates to the ulnar side, which greatly affects the daily life of the patient and increases the burden on the family and society. At present, the domestic clinical rehabilitation treatment method for stroke patients mainly adopts the traditional one-on-one training method between patients and doctors....
