Abstract
The utility model relates to an energy-saving foot core for a prosthetic foot. The utility model is characterized in that the energy-saving foot core for a prosthetic foot is composed of a C-shaped front keel (1), a C-shaped back keel (3) and an upper plate (2), wherein an opening of the C-shaped front keel (1) faces forwards; an opening of the C-shaped back keel (3) faces backwards; the C-shaped front keel and the C-shaped back keel are arranged in a back-to-back mode; the upper ends of the C-shaped front keel and the C-shaped back keel are connected with the upper plate. The C-shaped back keel releases energy to make the gravity centre of a human body rapidly transferred in the transition time from touchdown to weight-bearing period. The design of the C-shaped front keel makes a prosthetic foot user store energy from a support period transmitted to a liftoff period and release energy out from the liftoff period to a dynamic swing period to help the prosthetic foot complete the pedaling and parting action. The structural characteristic of division toes of the front keel makes the prosthetic foot have a buffer action when the prosthetic foot walks on a scraggy road surface to be suitable for topographical variation and help prosthetic users naturally to walk on the scraggy road surface. The arc designs of the front and the back keel make the gait of an amputee transmitted dynamically in the transient process form the support period to the swing period to make the gait soft, stable and natural.
Description
Technical field
This utility model relates to the prosthesis technique field, belongs to a kind of energy storage artificial foot foot core (being commonly called as Os Draconis), and this energy storage artificial foot foot core makes amputee's walking lighter, near normal person's walking step state.
Background technology
For the normal people of limbs, motion at ordinary times as hurry up, running, high jump, long-jump etc. all are nature and be easy to realize so, but for the amputee, these motions realize by prosthetic components fully, with the next compensatory normal human's of false foot ankle joint and foot function, therefore the performance of false foot and amputee's daily life is closely bound up.
Energy storing foot generally is to be made by high strength elastic carbon fiber or composite, in the time of exactly can be as the spring pressurized energy storage be got up, and once unclamping the false foot that can upspring automatically, it is lighter that it has the walking of making, and can run advantages such as jumping.These advantages of energy storage artificial foot mainly have benefited from its material behavior and architectural characteristic, and material behavior is confined to existing technical merit, improve quite difficult.The significantly raising that the structural design of innovation but can be brought the energy storing foot performance.So we start with from structure, the foot core of energy storing foot is innovated, make it more to meet the physiological characteristics of human body.
Summary of the invention
The purpose of this utility model provides a kind of energy storage artificial foot foot core, and it is that foot function according to the people designs, and Os Draconis used the design of 2C shape before and after its innovative design was, can bear human body walking and run the more large impact power of bringing of jumping.Before and after Os Draconis adopt arcuate structure, make amputee's walking step state lighter, nature.Adopt the foot core of the structure of 2C shape as false foot, simple in structure, light weight, good stability, impact resistance are strong.
To achieve these goals, this utility model adopts following design:
A kind of energy storage artificial foot foot core, it is characterized in that: it by C shape antitrope, C shape after Os Draconis and upper plate three parts constitute, the opening of described C shape antitrope forward, the opening of Os Draconis backwards after the described C shape, the back-to-back setting of Os Draconis after described C shape antitrope and the C shape, the upper end of Os Draconis is connected with upper plate after C shape antitrope and C shape.Forward and backward Os Draconis C shape design is for false foot provides excellent energy savings and playback function.
Described C shape antitrope front end landing part has gap, and heel is an arc after described C shape antitrope front end and the C shape.
This utility model and prior art have the following advantages:
When 1, the heel of false foot is contacted to earth after the C shape Os Draconis be subjected to force compresses, the sole of the foot power in the wrong of generation plays cushioning effect, thereby has significantly alleviated the influence to deformed limb, knee joint, hip joint and spinal column in the time of can absorbing heel and contact with ground.By the phase of landing when weight-bearing phase is excessive after the C shape Os Draconis release energy its gravity center of human body shifted rapidly.
2, general false foot energy in each gait cycle is all lossy, but antitrope C shape design has supporting false foot assembler and puts aside energy latter half, and pushing off the performance that the phase discharged naturally to the dynamic swing phase, and can produce motive force, impel knee sprung, allow the prosthetic user than long walk the time, not feel tired.
3, the design of C shape makes false foot have axial compressibility when load-bearing.
4, C shape antitrope landing part divides the toe architectural characteristic to make false foot when the walking of rough and uneven in surface road surface individual cushioning effect be arranged, the variation of adaptation to the ground, the walking of help prosthetic user nature on uneven ground.
5, to make amputee's the transient process of gait from the support phase to shaking peroid be the dynamic transition to the design of the forward and backward Os Draconis arc of C shape, makes gait softer, steady, natural.

The specific embodiment
Referring to Fig. 1, Fig. 2, shown in Figure 3: a kind of energy storage artificial foot foot core, it by C shape antitrope 1, C shape after Os Draconis 3 and upper plate 2 three parts constitute, make by carbon fibre or elastic composite.The opening of described C shape antitrope forward, after the described C shape opening of Os Draconis backwards, the back-to-back setting of Os Draconis after described C shape antitrope and the C shape, the upper end of Os Draconis is connected with upper plate 4 after C shape antitrope and C shape, adopts bonding mode to form integral body.Forward and backward Os Draconis C shape design is for false foot provides excellent energy savings and playback function.
On upper plate 4, be provided with installing hole 5, be used for being connected usefulness with artificial limb.
Described C shape antitrope front end landing part has gap 4, and its purpose of design is to make false foot can adapt to the influence on rough and uneven in surface road surface, helps prosthetic user's walking of nature on the ground.Os Draconis 3 rear ends are arc after described C shape antitrope 1 front end and the C shape.Arc design in forward and backward Os Draconis bottom surface meets the Human Physiology rule, and making amputee's gait is the dynamic transition in the transient process of three phases of walking (heel is contacted to earth phase, the phase of supporting, the phase of pushing off fully), and gait is softer, steady, natural.
