Embodiment Construction

[0011] like figure 1 As shown, the present invention includes a lower platform with a fixed support, an upper platform that can drive the handle to move according to the established motion law, and serves as a reference for each moving part; three active driving legs are used to limit the three degrees of freedom of movement of the upper platform The pillar, the upper and lower hinges of the three legs and the upper hinge of the pillar constitute a three-degree-of-freedom parallel mechanism, and a six-dimensional force sensor for detecting the motion law of the input handle and a handle for connecting and fixing the patient's hand. The connection between the three active driving legs and the upper and lower platforms adopts ball joints. The column and the lower platform are fixedly connected, and the upper platform is connected by ball joints. The three local degrees of freedom of the three active driving legs rotating around their own axes are removed, and the upper platform ...

Abstract

The invention discloses a non-wearable three degree freedom wrist rehabilitation robot comprising an upper platform, a lower platform, three driving support legs and one stand column. Three rotation freedom movements can be spatially achieved. The lower platform of the mechanism is fixed on the ground or other fixing plane; a six-dimensional force transducer is installed on the upper platform to detect wrist motion tracks and store the same during rehabilitation to a patient by a doctor; the six-dimensional force transducer can also feed back detection for handle motion information during the rehabilitation to achieve precise control on handle motions; the other surface of the six-dimensional force transducer is connected with a handle to fix a patient hand part; and the three support legs are connected with the upper and lower platforms via a spherical hinge to achieve free rotation of the upper platform. The non-wearable three degree freedom wrist rehabilitation robot can be applied to treatment of wrist diseases, motion damages and wrist post-surgery rehabilitation.

Description

technical field [0001] The invention relates to the field of rehabilitation medical robots, in particular to a wrist rehabilitation robot based on a multi-degree-of-freedom parallel mechanism. Background technique [0002] According to relevant surveys, the number of patients with wrist joint diseases in my country is increasing every year. In addition to drug treatment, wrist rehabilitation training is an essential part of the rehabilitation treatment of wrist joint diseases, sports injuries and wrist surgery. treatment approach. Wrist rehabilitation training requires professional doctors to guide patients to perform relevant movement exercises, which is a highly technically demanding and repetitive task, and regular treatment by professional doctors will also increase the treatment cost of patients. The wrist rehabilitation treatment system can be used for rehabilitation treatment of wrist joint diseases, sports injuries and wrist surgery. Through certain technical means,...
