Joint compound motion mechanical arm used for rehabilitation training of upper limb

Abstract

The invention discloses a joint compound motion mechanical arm used for rehabilitation training of an upper limb. The mechanical arm comprises a base, an electric lifting column, a T type supporting frame, a main fixed base and an outer skeleton mechanical arm system, wherein the base is placed on the ground; the electric lifting column is fixedly connected with the base; the electric lifting column is fixedly connected with the T type supporting frame; the main fixed base is mounted on a supporting frame; the outer skeleton mechanical arm system is connected with driving motors through the main fixed base; and the driving motors are all mounted on the main fixed base. When the mechanical arm is in use, only the outer skeleton mechanical arm system moves according to a control instruction; the motors are motionless relative to the base; the mechanical arm is light, convenient and flexible, creative in structure, small in occupied space, and stable and reliable in movement; the joint compound motion mechanical arm can be used for assisting a patient with upper limb dyskinesia to finish all kinds of rehabilitation training actions; and meanwhile, the mechanical arm can be used for single-joint rehabilitation training for a shoulder joint and an elbow joint, and also can be used for compound motion rehabilitation training for multiple joints of the upper limb.

Description

technical field [0001] The invention relates to an auxiliary medical rehabilitation training device, in particular to an upper limb rehabilitation training mechanical arm, which is an upper limb rehabilitation robot suitable for performing exercise rehabilitation training on the upper limbs of patients with upper limb motor function such as hemiplegia. Background technique [0002] For the training and rehabilitation of human upper limb motor function, the traditional rehabilitation training method mainly involves the therapist manually assisting the patient in training according to experience. The training effect is affected by the level of the therapist, and the work intensity of the therapist is also very high. In the past 20 years, some research institutions at home and abroad have carried out research on upper limb rehabilitation training technology, and developed a variety of upper limb rehabilitation robots and rehabilitation training equipment with different functions...
