Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of artificial limb foot plates, in particular to an enhanced elastic foot plate for left and right split-toe artificial limbs. Background Art
[0002] The prosthetic foot is an important component of prosthesis, used to simulate the functions of the human foot and help amputees regain the ability to walk, stand and carry out other daily activities. The prosthetic foot supports the patient's weight through its sturdy structure, enabling them to stand and walk.
[0003] In the existing technology, prosthetic foot plates can reduce the pressure and burden on healthy legs and prevent joint diseases and other injuries. However, most existing prosthetic foot plates only simulate toe support through simple slits, which cannot well simulate the gait of a normal foot, allowing patients to walk more naturally, thereby increasing the risk of falls and sprains, and are not conducive to use as walking support. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the utility model provides an enhanced left and right split-toe prosthetic elastic foot plate, which solves the problem that the existing prosthetic foot plates simulate toe support through simple slits and cannot well simulate the gait of a normal foot, allowing patients to walk more naturally.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an enhanced elastic foot plate for left and right split-toe prostheses, comprising an arched foot arch, an L-shaped middle plate fixedly connected to the upper surface of the arched foot arch, a front side of the L-shaped middle plate fixedly connected to a reinforced upper plate extending along the surface thereof, the front end of the reinforced upper plate being shorter than the front end of the L-shaped middle plate;
[0006] The front end of the arched foot arch is provided with a forefoot fork, and the front end of the arched foot arch forms a thumb plate and a toe plate through the forefoot fork. The front end of the L-shaped middle plate is provided with a first mid-palm fork adapted to the forefoot fork, and the front end of the reinforced upper plate is provided with a second mid-palm fork adapted to the forefoot fork.
[0007] Furthermore, the side wall of the arched arch is provided with a curved foot side.
[0008] Furthermore, a curved heel is provided at the rear end of the arched arch, and the rear end of the curved heel is bent downward.
[0009] Furthermore, a first connecting hole is provided on the lower surface of the arch-shaped foot arch and the front end of the upper surface of the L-shaped middle plate.
[0010] Furthermore, a second connection hole is formed at the top end of the front side surface of the L-shaped middle plate and the top end of the front side surface of the enhanced upper plate.
[0011] Furthermore, an arch bridge arc side is provided at the front end of the lower surface of the enhanced upper plate.
[0012] Furthermore, the arch-shaped arch, the L-shaped middle plate and the reinforced upper plate are all made of carbon fiber.
[0013] Compared with the existing technology, the beneficial effects of the present invention are that the thumb plate and the toe plate are formed by the forefoot fork, so that the force distribution on the sole of the foot is more reasonable, toe support is simulated, and the gait of a normal foot is better simulated. In addition, combined with the first mid-foot fork and the second mid-foot fork, the patient can walk more naturally, thereby reducing the risk of falling and sprains, improving stability and safety during walking, and facilitating the use of walking support. The main function of the prosthetic foot plate is to bear the body's weight, transfer the force of the residual limb to the ground, and compensate for some functions of the human foot. Carbon fiber has high elasticity and the functions of energy storage and energy feedback. The enhanced support ensures safety and stability during instantaneous impact force and safe support when wearing the prosthesis, meeting the use needs of amputees in different scenarios.
