Description
Technical field
The present invention relates to human body prosthesis technique field, more particularly to a kind of light intelligent energy storage and energy release ankle-joint artificial limb.
Background technology
Today's society, because the reasons such as traffic accident, disease cause the colony of below-Knee amputation gradually to increase, and for lower limb
Amputee's mode for compensating its locomotor activity defect most common at present is wheelchair, crutch and artificial limb.Wheelchair floor space is larger,
And the place that wheel type machine can not reach is limited to, such as stair are walked.The use of crutch occupies the function of both hands, reduces
The body function of wearer.Wearing artificial limb can reach the compensatory of human body missing function, and in ornamental and walking comfort etc.
Aspect has advantage.
At present, the species of ankle-joint artificial limb is a lot, classifies by type of drive, mainly there is passive and active ankle-joint artificial limb.
Passive ankle-joint artificial limb is to make sole using materials such as rubber, carbon fibers, or the energy storage device such as introducing spring makes in mechanism
Obtaining pin integrally has certain elasticity；But passive ankle-joint at present on the market is generally heavier, row after individuals with disabilities's wearing
Walk dumb.Passive ankle-joint artificial limb has the advantages such as mechanism is simple, in light weight, energy expenditure is low, but due to passive ankle-joint
Artificial limb passive delivery, patients with amputation walking and normal limb movement locus mismatch problem be present.Active ankle-joint artificial limb be
The active drive device such as motor is introduced in prosthetic device, major advantage is that the number of degrees of freedom, of artificial limb anklebone joint is more, wearer's
Gait compared with naturally, and adapt to different road conditions, but there is artificial limb system in active ankle-joint artificial limb then due to introducing driver element
Weight of uniting is big, high energy consumption, it is expensive the shortcomings of, and the number of degrees of freedom, of artificial limb anklebone joint is not necessarily part good thing more, because greatly
Leg patients with amputation loses knee joint, and multivariant ankle-joint is difficult to control, and easily causes ankle support unstable, so as to
Wearer is set to fall.
The content of the invention
In order to solve the above technical problems, a kind of cost of present invention offer is low, comfortable intelligent energy storage of being walked after light, wearing
