Summary of the invention
The objective of the invention is to be to overcome above-mentioned weak point, a kind of carbon fiber energy storage pseudarthrosis prosthetic feet of simulating the intertarsal joint function of a kind of intensity height, light weight, good springiness, comfort in walking is provided.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of carbon fiber energy storage pseudarthrosis prosthetic feet of simulating the intertarsal joint function comprises S shape upper plate, lower plate, syndeton, is characterized in: also comprise heel shell fragment, trapezoid groove structure; Said trapezoid groove structure upper surface is level, and is fixedly connected with syndeton, and the lower surface is 30 degree and tilts; And be fixedly connected with the heel shell fragment; The big backward notch of the little notch of trapezoid groove structure forward, S shape upper plate passes from notch, and is connected with syndeton; Heel shell fragment opening is connected with lower plate below it backward.
The upper bend part opening of S shape upper plate forward, lower knuckle partly be false foot metatarsal and opening backward.
Lower plate is divided into heel arch of the foot toe three parts, and toe portion is upturned and is shape when toe lands in the normal foot walking, and partly is connected with the lower knuckle of S shape upper plate.．
The position that lands of lower plate is an arc transition, and arch of the foot partly is protruding, imitation arch shape.
The present invention has following beneficial effect:
1, when the wearer of false foot when upright, because of S shape upper plate passes and heel shell fragment independent design from dovetail groove, heel and forefoot can be redistributed pressure behind the pressurized; Independent pressure-bearing; Realize vertically being evenly distributed of pressure, shank is remained vertically, can not lean forward and also can not swing back; And dovetail groove is when completion makes upper plate and heel independent design, can (4L 4H) passes to heel, and the structure of this both sides power transmission has guaranteed the left and right sides balance of foot and the steadiness that sole supports from the trapezoid groove structure both sides with the pressure that bears; S shape upper plate upper bend part also can produce the fine motion distortion in walking, can with ankle joint associating activity, and cooperate the dorsiflex and the stretching, extension of foot, simulate the power transmission and the fine motion function of intertarsal joint, make its motion more natural.
2, when heel from phase of landing during to the weight-bearing phase transition; The heel shell fragment is compressed; 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 compressed heel shell fragment can storage power simultaneously.
3, when heel from weight-bearing phase during to liftoff phase transition, bounce-back discharges energy to the heel shell fragment to the front upper place, helps heel to accomplish liftoff action.Heeloff; Forefoot from the phase of landing to the weight-bearing phase transition; This moment, S shape upper plate lower knuckle partly was compressed and storage power, ' when forefoot from weight-bearing phase during to liftoff phase transition, S shape upper plate lower knuckle partly rebounds and releases energy; Steadily, drive gradually liftoff of forefoot naturally; And be shape when toe lands in the normal foot walking because toe portion is upturned, thus can make the position that lands carry out the transition to toe steadily, naturally by forefoot, accomplished the function of simulation metatarsophalangeal joints motion.
4, the position that lands of lower plate all is an arc transition; And it is protruding that arch of the foot partly is, imitation arch shape, thus the wearer that can make false foot is in the process of walking; No matter be from the phase of landing to the weight-bearing phase transition; Or to liftoff phase transition, all belong to the dynamic transition from weight-bearing phase, gait can more steady, graceful, nature.
