Abstract
The utility model relates to a double-side elastic all-terrain artificial foot board which comprises a connecting structure. The utility model is characterized in that the double-side elastic all-terrain artificial foot board further comprises a double lower board, an upper board, a U-shaped front keel and a U-shaped back keel; the upper board and the double lower board are fixedly connected through the U-shaped front keel and the U-shaped back keel; and the openings of both the U-shaped front keel and the U-shaped back keel face backwards; and both the U-shaped front keel and the U-shaped back keel release respective stored energy when a heel is in the transition from the weight bearing period to the land-leaving period and a front sole is in the transition from the weight bearing period to the land-leaving period, so as to help the artificial foot to complete the stepping movement. The utility model has the characteristics of high strength, light weight, good elasticity, comfort walking, etc.
Description
Technical field
This utility model relates to a kind of artificial limb, and especially a kind of double-side elastic all-terrain artificial feet plate (being commonly called as Os Draconis), this vacation foot sole can make the wearer walking more free and relaxed, near normal person's walking step state.
Background technology
Because the weight of artificial limb has direct influence to the energy that the lower extremity amputation patient moving is consumed, thereby can have influence on the effect that the patient dresses artificial limb, therefore, in designing and producing artificial limb parts process, should take into full account satisfy the patient and require function in, select lower limb accessory in light weight, as can to reduce physical demands as far as possible.False foot is as the important composition parts of artificial leg, and its major function is to support body weight, and the work of compensatory at the volley triceps surae and musculus flexor is in order to keep the posture of the normal walking of health.Concerning the lower extremity amputee, the weight of false foot and function will directly influence amputee's walk, thereby have determined the quality of artificial limb to a great extent.Especially for older, poor physical capacity, or,, can cause the stressed excessive of deformed limb, increase the burden of strong limb side simultaneously, even therefore caused the both legs amputation, bring bad consequence if the weight of artificial limb is excessive because of the patient of disturbance of blood circulation amputation.So the lightweight that how realizes false foot on the basis that guarantees false foot function has caused the extensive concern of researcher.
At present, the inner frame of artificial limb sole generally adopts making such as timber, rubber, also have minority to adopt the carbon fiber of intensity height, light weight, but structural design is not very desirable, makes the wearer walking feel still uncomfortable.Though also released some advanced carbon fiber products abroad, cost an arm and a leg, be not suitable for vast patients with amputation consumption, and structure remains still to be improved.
Summary of the invention
The purpose of this utility model is to be to overcome above-mentioned weak point, and a kind of intensity height, light weight, good springiness, the comfortable double-side elastic all-terrain artificial feet plate of walking are provided.
For achieving the above object, this utility model adopts following design:
A kind of double-side elastic all-terrain artificial feet plate comprises syndeton, is characterized in: also comprise two lower plates, upper plate, U-shaped antitrope, Os Draconis behind the U-shaped, fixedly connected with Os Draconis behind the U-shaped with the U-shaped antitrope between described upper plate and the two lower plates, and behind U-shaped antitrope and the U-shaped keel structure opening all backward.
Two lower plates and upper plate are the arcuate structure of the normal sole of imitation, and wherein, two lower plates then are made up of two blocks of identical bionical arcuate structure plates, and the branch interdigit is left in the centre.
The lower end of Os Draconis all has gap behind U-shaped antitrope and the U-shaped, and is connected with two lower plates by gap.
The mid portion of two lower plates is provided with projection, the wearer that makes false foot in the process of walking, no matter be from the phase of landing to the weight-bearing phase transition, still from weight-bearing phase to liftoff phase transition, all can make gait more steadily, graceful, nature.
The utlity model has following advantage:
1, when heel from phase of landing during to the weight-bearing phase transition, Os Draconis are compressed behind the opening U-shaped backward, the impulsive force that produces in the time of can absorbing heel and contact with ground, thus influence alleviated to deformed limb, knee joint, hip joint and spinal column, and Os Draconis can storage power behind the compressed U-shaped simultaneously.From weight-bearing phase during to liftoff phase transition, the Os Draconis bounce-back discharges energy behind the U-shaped, helps heel to finish liftoff action at heel.
2, for farthest reducing the energy loss in each gait cycle, improve the energy storage ratio of false foot, designed opening U-shaped antitrope backward at the forefoot place, after heeloff, forefoot from the phase of landing to the weight-bearing phase transition, this moment, the U-shaped antitrope was compressed and storage power, when forefoot from weight-bearing phase during to liftoff phase transition, the bounce-back of U-shaped antitrope releases energy, and helps forefoot to finish liftoff action.Thereby the energy loss of each gait cycle can be dropped to minimum, even can not feel tired when making wearer carry out the outdoor activities of long period yet.
3, at the lower plate design aspect of false foot, adopted two blocks of identical bionical arcuate structure plates, thereby made false foot have branch toe characteristic, can adapt to rugged pavement structure automatically, strengthened the safety of false foot and functional.
4, the front and rear surfaces of two lower plates all adopts arcuate structure, mid portion has projection, thereby the wearer that can make false foot in the process of walking, no matter be from the phase of landing to the weight-bearing phase transition, still be to liftoff phase transition from weight-bearing phase, all belong to the dynamic transition, gait can more steady, graceful, nature.
5, the agent structure of whole foot core for artificial foot has adopted carbon fibre composite in light weight, that intensity is high, the life-span is long to make, and meets to guarantee false foot function and realize the light-weighted design concept of false foot.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further described.
As shown in Figures 1 to 4, a kind of double-side elastic all-terrain artificial feet plate, it by two lower plates 1, U-shaped antitrope 2, U-shaped after Os Draconis 3, upper plate 4 and syndeton 5 form.Syndeton 5 adopts metal material to make, and other structures all adopt the carbon fibre composite to make.The described pair of lower plate and upper plate are the arcuate structure of the normal sole of imitation, Os Draconis after being U-shaped antitrope and U-shaped between the upper and lower plates, and the opening of U-shaped structure is all backward.The upper end of syndeton 5 connects ankle joint, behind upper plate and the U-shaped between the Os Draconis lower end by syndeton 5 be connected, the connection of other structures is all adopted adhesive bond together.Combined effect by Os Draconis before and after the opening U-shaped backward can make false foot finish the whole action that pushes off like a cork.
The lower end of Os Draconis is the gap structure before and after the described U-shaped, so that be connected with two lower plates.Two lower plates have identical bionical arcuate structure, have branch toe characteristic, can make false foot automatically adapt to rugged pavement structure, thereby help the wearer can walking naturally under different road conditions, have strengthened the safety of false foot and functional.In addition, the front and rear surfaces of two lower plates all adopts arcuate structure, and mid portion has projection, thereby the wearer that can make false foot in the process of walking, no matter be from the phase of landing to the weight-bearing phase transition, still from weight-bearing phase to liftoff phase transition, all can make gait more steadily, graceful, nature.
