Description
Technical field
The present invention relates to a kind of human motion auxiliary device, relate in particular to a kind of be applicable to hand function impaired patients based on memory alloy driven exoskeleton rehabilitation system.
Background technology
Hands is that human body is the most complicated, one of most important organ, yet is also a position very easily sustaining damage.The injured often recovery period of hand is long, how undesirable to completing the functional rehabilitation of fine movement, has had a strong impact on patient's quality of life.How to promote to hinder rear hand functional rehabilitation, oneself seems most important.
Nineteen sixty, Canadian orthopedist Robert Salter has proposed Continuous Passive Movement rehabilitation therapy (Continuous Passive Motion is called for short CPM).By external force, driving suffering limb to do long-time FR passive activity, with this, stop the stiff of sufferer joint, and promote suffering limb blood. liquid circulation reaches the object of fast track rehabilitation.CPM therapy has been proved successful, but the feature of this high strength high duplication has proposed very high request to Physical Therapist's labor intensity.In order to tackle this problem, robot and correlation technique thereof are applied in hand rehabilitation, by hand exoskeleton system, replace Physical Therapist, drive suffering limb to carry out passive exercise, promote hand function to recover.
Occurring in nature, ectoskeleton is a kind ofly can provide the hard external structure of biological soft inside organ being carried out to configuration, building and protection.Shrimp, Eriocheir sinensis etc. are all that typical ectoskeleton is biological.From biological ectoskeleton, gain enlightenment, scientist develops a series of mechanical exoskeletons, by mechanical external force, the people of amyotrophy or brain or spinal function damage is assisted in the situation that helping without manpower, helps people with disability, old people to carry out daily life.
In each joint of human body, the joint freedom degrees of finger is many, and structure is also complicated, so the ectoskeletal design of hand is also more difficult.Through the literature search of prior art is found, domestic to the ectoskeletal research of hand also in the starting stage.Chinese Patent Application No. is: 201110121085.5 patent of invention discloses a kind of fixed hand exoskeleton rehabilitation device.This device drives feed screw nut to obtain power by motor, simple in structure, and is easy to realize.But also there is following problem:
(1) ectoskeleton driving device is motor, and volume is large, quality weight, in during rehabilitation training, to patient, brings larger burden.Therefore hand ectoskeleton has to make fixed, by pedestal, carries driving device weight, has affected the portability of whole system.
(2) the hand rehabilitation ectoskeleton of traditional passive type, good rehabilitation exercise prepared in advance, action is simple, form is single, affects rehabilitation efficacy.Along with the development of the machining surface signal of telecommunication (Electromyography, be called for short EMG) technology, develop the active rehabilitation system being brought out by patient and become and be extremely necessary.

The present embodiment provide based on memory alloy driven hand exoskeleton rehabilitation system, by collection surface electromyographic signal, analyze and draw hand muscular movement intention, control hand ectoskeleton and do corresponding sports, drive patient's finger movement, reach autonomous reconditioning effect.
Below in conjunction with specific embodiment, the control instruction of " forefinger portion is crooked " and " stretch middle finger " of take and input is elaborated to work process of the present invention as example.
Work process of the present invention comprises the following steps:
Step l, patient's hand puts on one's gloves 1, has dressed hand ectoskeleton.Surface electromyogram signal Acquisition Instrument imports the hand muscle signal of telecommunication collecting in computer into, and computer analysis draws the motion intention of hand muscle, and passes to hand ectoskeleton as control instruction.
Step 2, when control instruction is " forefinger portion is crooked ", constant-current source is connected in the marmem extension spring 11 in forefinger portion power source 3, is heated to phase transition temperature, produces shape memory effect.Marmem extension spring 11 is initiatively shunk under shape memory effect effect, drives No. one, MCP joint connecting rod 14 to rotate around palm plate support bar 10.Meanwhile, No. one, MCP joint connecting rod 14 promotes No. two, MCP joint connecting rod 15 and rotates with MCP articular branches strut 19, drives patient's the MCP of forefinger portion arthrogryposis.The rotation of No. two connecting rods 15 in MCP joint, under the transfer function of driving gear 20, driven gear 2l, causes No. one, PIP joint connecting rod 16 also to rotate.No. one, PIP joint connecting rod 16 promotes No. two, PIP joint connecting rod 17 and rotates with PIP articular branches strut 18, drives patient's the PIP of forefinger portion arthrogryposis.
Step 3, when control instruction is " stretch middle finger ", the marmem extension spring 11 in middle finger power source 3 breaks from heater circuit, and temperature is reduced to below phase transition temperature, and shape memory effect disappears, and no longer produces contractility.The common straightcarbon steel extension spring 12 being stretched is shunk under self restoring force effect, drives No. one, MCP joint connecting rod 14 to rotate backward around palm plate support bar 10.Meanwhile, No. one, MCP joint connecting rod 14 promotes No. two, MCP joint connecting rod 15 and rotates backward with MCP articular branches strut 19, drives patient's MCP joint, middle finger to stretch.Rotating backward of No. two connecting rods 15 in MCP joint, under the transfer function of driving gear 20, driven gear 21, causes No. one, PIP joint connecting rod 16 also to rotate backward.No. one, PiP joint connecting rod 16 promotes No. two, PIP joint connecting rod 17 and rotates backward with PIP articular branches strut 18, drives patient's PIP joint, middle finger to stretch.
Above specific embodiments of the invention are described.It will be appreciated that, the present invention is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect flesh and blood of the present invention.
