Abstract

The invention discloses an open-loop adjustable wrist joint rehabilitation training exoskeleton, which relates to a rehabilitation training exoskeleton. The problems that an existing closed-loop wristjoint rehabilitation exoskeleton is inconvenient to wear, lag and looseness exist in steel wire transmission, and installation and maintenance are inconvenient are solved, and the problem that the exoskeleton cannot be used for different patients is solved. A wrist spinning assembly (2) is installed on a base assembly (1) and rotates in the circumferential direction along the base assembly (1). Wherein a wrist flexion and extension assembly (3) is installed on the right side of the wrist spinning assembly (2), a wrist deflection assembly (4) is installed at the tail end of the wrist flexion and extension assembly (3), a handle assembly (5) is installed on the wrist deflection assembly (4) and adjusts deflection of the wrist of a patient, and a forearm guard plate assembly (6) is installedon the base assembly (1) and the wrist flexion and extension assembly (3). The device is used for wrist joint rehabilitation training.

Description

technical field [0001] The invention relates to a training exoskeleton, in particular to an open-loop adjustable wrist joint rehabilitation training exoskeleton. Background technique [0002] After a wrist injury, long-term immobilization and lack of movement of the wrist joint will lead to adhesion and contracture of muscles and tendons, resulting in complications such as wrist joint swelling, pain, limited mobility, and decreased muscle strength. There are many methods of wrist rehabilitation, such as drug therapy, external stimulation, rehabilitation training and so on. But if you want to really restore the normal movement function of the wrist joint, you must rely on rehabilitation training. Rehabilitation training at this stage mainly relies on rehabilitation physicians, but it also exposes many problems, which are time-consuming and costly. The training effect depends on the treatment level of rehabilitation physicians and factors such as the doctor's subjective consc...
