Exoskeleton finger function rehabilitation device based on multi-section continuous structure

Abstract

The invention relates to an exoskeleton finger function rehabilitation device based on a multi-section continuous structure. The exoskeleton finger function rehabilitation device comprises a finger driving mechanism pasted on a glove module through a hook-and-loop fastener, the finger driving mechanism is connected with a linear push rod motor, the linear push rod motor is fixed to a loading platform, and the loading platform is connected to the sleeve module and located at the forearm position of the injured hand; the finger driving mechanism comprises an exoskeleton index finger driving mechanism, an exoskeleton middle finger driving mechanism, an exoskeleton ring finger driving mechanism and an exoskeleton little finger driving mechanism covering the metacarpophalangeal joint end, the proximal finger joint end and the distal finger joint end of all exoskeleton fingers; the linear push rod motor drives spring sheets to move forward to cause the spring sheets to deform and bend and drive the fingers to bend, and when moving backwards, the linear push rod motor drives the fingers to stretch. The exoskeleton finger function rehabilitation device is capable of providing CPM rehabilitation training on a patient and is simple and compact in structure and adaptive to fingers of different patients in size.

Description

technical field [0001] The invention relates to a human body movement rehabilitation device, in particular to an exoskeleton finger function rehabilitation device based on a multi-segment continuous structure. Background technique [0002] As we all know, the hand is one of the most important organs of the human body. Accidental injury, stroke, etc. will cause hand motor function impairment and affect the daily life of patients. Scientific exercise training can help patients rebuild or improve the function of the affected hand. CPM (Continuous passive motion), continuous passive motion, is a new rehabilitation medical theory proposed by Canadian orthopedic surgeon Salter RB in the 1970s to prevent joint stiffness and improve joint mobility. In the early stage of hemiplegia, CPM rehabilitation training for patients can effectively improve the function of the affected limbs. However, the current rehabilitation treatment mainly involves "one-on-one" rehabilitation training fo...

Problems solved by technology

However, the current rehabilitation treatment mainly involves "one-on-one" rehabilitation training for patients by rehabilitation physicians, which brings the following problems: high cost, requiring a lot of physical and energy from therapists and patients, which restricts patients from completing sufficient rehabilitation training; It is extremely dependent on the level of rehabilitation physicians themselves, and it is difficult to accurately control rehabilitation training parameters

However, the existing hand function rehabilitation equipment has the following shortcomings: poor wearability, large weight and size, which affects the patient experience; it cannot adapt to the difference in the length of individual fingers of patients; most rehabilitation equipment is a rigid body linkage mechanism, and the joint center and the connecting rod There is a deviation in the rotation center of the mechanism, and a slight deviation will cause secondary injury to the patient; the fingertips are often not free, and the entire hand is bound in the rehabilitation equipment, which does not provide the function of the affected hand, especially the fingertips, to interact with objects, and cannot carry out daily life Action assist function
