Abstract

A power-assisted leg is for a patient with leg bone joint diseases and weak joint bearing capability, and can help the patient to normally work; the technology is that metal pipe type material is segmented, and segments are connected through a rotary hinge, and are bonded with each leg portion, so a walking function of the leg is used for simultaneous movements. The power-assisted leg is connected with each leg portion through a bearing seat and bands; an elastic buffer device can mitigate instant impact on a hipbone bottom when touching down; in addition, the power-assisted leg needs to be adjusted to a proper height in usage, the height needs to be a little bit higher than the real height of a human leg so as to digest tension level of the bearing seat, and the height of the power-assisted leg cannot be too high, which will suspend the patient so as to lost normal walking control capability; the height of the power-assisted leg cannot be lower than the patient leg, which means the meaning of the power-assisted leg is lost; the property height is that when the body weight falls on the power-assisted leg, the weight will be carried by the power-assisted leg instead of being carried by the bone joint, and the bone joint is not overly loaded. The power-assisted leg can solve the joint burden problems caused by the weight of the patient with bone joint diseases.

Description

Power-assisted lower limb
Technical field
This technology is suitable for the patient that leg osteoarthrosis and joint weight capacity weaken, and is a kind of power-assisted lower limb born joint and bear a heavy burden.
Background technology
The patient of current leg osteoarthrosis, only disperses by means of crutch or wheelchair or bears body weight to move the health of oneself, making patient's action very inconvenient, and severe patient can only be performed the operation and be changed joint, there is no the better measure preventing or alleviate joint wear at present.
Summary of the invention
The invention solves the burden of own wt to joint of leg osteoarthrosis patient, can prevent or alleviate increasing the weight of of joint wear, namely using can the power-assisted lower limb of support human body weight, drives power-assisted lower limb synchronization action with the original walking function of patient's lower limb.
The technical solution adopted in the present invention is: according to the different distance of leg ankle arthrosis and knee joint, knee joint and hip joint, corresponding length is made and with rotating chain connection with metal tubular product material, be equipped with suitable elastic buffering mechanism, power is acted on thigh root and hipbone position by bearing pressure seat, as the position of acrobatics single wheel vehicle seat under hip, by power-assisted lower limb by reaction force acts in ground.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of power-assisted lower limb attached generation " model ", and Fig. 2 is the side schematic view of Fig. 1,1. bearing pressure seats in figure, supports 2., 3. joint pin in, 4. spherical linkage pin, 5. elastic buffering mechanism, 6. lower support, 7. lower limb bandage, 8. foot bandage, 9. plays joint pin, 10. pedal.
Detailed description of the invention
According to Fig. 1, Fig. 2 and accompanying drawing explanation, can understand that power-assisted lower limb is connected together by bearing pressure seat, lower limb bandage, foot bandage and each position of lower limb, drive and synchronization action with the walking function of lower limb, the effect of bearing pressure seat is with soft mode and Body contact, slow down counteracting force when contacting to earth, the effect of elastic buffering mechanism is alleviate the impact to moment bottom hipbone when contacting to earth equally, and the effect of shape hinge ball allows lower limb not only swing can also have the activity moved left and right.
Use in addition during power-assisted lower limb and also need to adjust its suitable height, certain left and right lower limb wherein one bending time be not too stressed, another stretch travel forward be stressed maximum time, so this height will must exceed a bit than the actual height of lower limb, be used to digest the relaxation degree of bearing pressure seat and the amount of recovery of elastic buffering mechanism, can not be too high, too high meeting makes people unsettled and loses the controling power of normal walking, the meaning using power-assisted lower limb can not be lost lower than lower limb length, be exactly that body wt is when dropping on power-assisted lower limb, just in time to bear by power-assisted lower limb and osteoarthrosis is stressed not too much, this just serves the enforcement object of the technology of the present invention.

Claims (4)

1. power-assisted lower limb, its feature: make lower support with metal tubular product material, connect, connect together, exert all one's strength and act on bottom hip stock with bandage and lower limb with hinges, makes each joint of lower limb not stress or lacks stressed.
2. its additional characteristic feature 1 of power-assisted lower limb according to claim 1: be equipped with elastic buffering mechanism, the impact produced during for reducing instantaneous touch time stressed bottom hip stock.
3. its additional characteristic feature 2 of power-assisted lower limb according to claim 1: be equipped with bearing pressure seat with soft mode and Body contact, slow down counteracting force when contacting to earth.
4. its additional characteristic feature 3 of power-assisted lower limb according to claim 1: be realize lower limb with spherical linkage not only swing can also have the activity moved left and right.
