Abstract
The utility model relates to an artificial limb gait tester of artificial lower limbs, which comprises simulating legs, a power source, a driving device and a measuring and controlling system, wherein the measuring and controlling system comprises four angler displacement sensors, a data collection module, a motion control card and a computer processing system, the computer processing system is fixed on an outer box body on the ground by a bracket, the four angler displacement sensors are respectively positioned on two hip joints and two knee joints to collect the joint angle variation of the simulative gait, and a collected signal is transmitted to the computer processing system by the data collection module. When a human body normally walks, collected gait joint angle data in a whole gait cycle is used as a control signal, the power source is controlled by the motion control card, and the simulating legs are driven by the output of the power source to move through the driving device to realize the simulation of the walking gait of the normal human body. The artificial limb gait tester can basically simulate the normal gait of a human body and can supply a viable testing platform for further carrying out the objective appraisal of artificial limb performance.
Description
Technical field

Background technology
National people with disability's sampling survey data show present physical disabilities person of China returns society up to 2,412 ten thousand people again in order to make this some people for the second time, just must improve the prosthesis technique level in all directions, improves prosthetic function, improves patient's rehabilitation outcome.And in the development process of artificial limb, study and check its performance, the most direct experimental technique is that the amputee dresses, and does not test during the stage and is difficult to carry out but enter practicability as yet at artificial limb, and different people has different evaluations to identical artificial limb, has certain subjectivity.So the compensation of estimating artificial limb comparatively objectively and being possessed just becomes the inexorable trend of artificial limb research.But domestic present equipment and the instrument that to estimate artificial limb gait performance that still do not have relatively objectively.Therefore, be necessary to set up relatively objectively artificial limb gait test system of a cover.
Summary of the invention
This utility model is to solve the technical problem of estimating artificial limb gait performance objectively, and provide a kind of artificial artificial leg gait test device, for artificial limb designs and research and development provide platform, with respect to normal person's walking step state the gait of artificial limb is estimated, detect the performance of prosthetic product; One of this assay device function: can simulate the reproduction normal person walking step state, promptly with normal human's walking step state hypozygal angle over time curve as the control source, the motion of control device simulated leg, the reproduction normal person walking step state; Two of its function is: realize test evaluation to artificial limb gait performance, the simulation thigh or (with) gait when the below knee amputation people with disability walks, the situations such as artificial leg joint angles variation of installing behind the artificial limb are tested and are analyzed.
For achieving the above object, the technical solution adopted in the utility model is: a kind of artificial artificial leg gait test device is made up of simulated leg, power source and actuating device and TT﹠C system, simulated leg comprises trunk, thigh, shank, sole, hip joint, knee joint, thigh damping structure, shank damping structure, two cover counter weight constructions, be characterized in: power source comprises drive stepping motor and stepper motor driver; TT﹠C system comprises four angular displacement sensors, data acquisition module, motion control card, computer processing system, computer processing system is fixed in the outer case on ground through support, four angular displacement sensors lay respectively at two hip joints and two knee joint places, be used for gathering the joint angles variation of simulation gait, and the signal of gathering is transferred to computer processing system by data acquisition module, computer processing system is through the software of control system and acquisition system, when the human body of gathering is normally walked in the complete gait cycle gait joint angles data as control signal, by motor control card control power source, the output of power source is used to realize the simulation of normal human's walking step state through the motion of actuator drives simulated leg.
Large and small lower limb damping structure is installed in respectively on the large and small lower limb to thigh and shank provide damping force, prevents vibration.Counter weight construction is installed in below the trunk and is used for adjusting ground reaction force in the support, the gait of simulation different weight human body.
The beneficial effects of the utility model are:
Assay device of the present utility model, can simulate the walking step state of human body two legs, artificial limb is installed on this device, the simulation patients with amputation is installed the walking step state feature behind the artificial limb, thereby artificial limb is provided a relatively objective data evaluation, realized the performance of prosthetic product being estimated, the evaluation of artificial limb gait has been transferred to unified objectivity evaluation by the subjective feeling of original the disabled from the angle of machinery.Simultaneously,, analyze it and produce reason, and then artificial limb is improved, make the design of artificial limb progressively be tending towards perfect based on the difference of artificial limb gait and normal gait.
