Embodiment Construction

[0018] The present invention will be described in detail below with reference to the drawings and embodiments.

[0019] Such as figure 1 As shown, the present invention includes an integral foot plate 1, a toe joint 2 and a lower leg prosthesis 3.

[0020] Such as figure 2 As shown, the integral foot board 1 of the present invention includes an upper foot board 11 arranged obliquely, a heel elastic piece 12 is arranged under the upper foot board 11, and the front part of the heel elastic piece 12 is fixedly connected to the middle of the bottom surface of the upper foot board 11. There is an elastic movement space between the rear part and the upper foot board 11.

[0021] Such as image 3 As shown, the above-mentioned integral foot board 1 can also be provided with only one foot board 13, and the middle part of the foot board 13 has a higher bow.

[0022] Such as Figure 4 As shown, the toe joint 2 of the present invention includes a motor 21 mounted on the integral foot plate 1 thr...

Abstract

The invention relates to dynamic below-knee prosthesis with a continuous flexible toe joint. The dynamic below-knee prosthesis is characterized by comprising a whole sole, a toe joint and a below-knee prosthesis; and the toe joint comprises a motor arranged on the whole sole through a support, the motor is connected with a connecting rod through a driving mechanism, the other end of the connecting rod is rotationally connected with a pressing block, the pressing block is placed on the top surface of the front end of the whole sole, and the below-knee prosthesis is fixedly connected or hinged to the top surface of the rear part of the whole sole. The dynamic below-knee prosthesis has the advantages of high movement coherence, capability of being independently installed or replaced and capability of providing continuous flexible power for movement of a shank of a user, and can be widely applied to various amputees of different degrees.

Description

Technical field [0001] The invention relates to an under-knee prosthesis, in particular to a dynamic under-knee prosthesis with continuous flexible toe joints that combines active and passive motion modes. Background technique [0002] With the increase of various natural disasters, diseases and traffic accidents, the number of people with disabilities has increased year by year, and the demand for prosthetics has also increased. The toe joint is the most frequently active part of the human body during exercise, and it is also the main force-receiving part during exercise, especially the first part of the body to touch the ground at the moment the human body falls. It has greater elasticity and cushioning effect, and also provides for the movement of the calf. Flexible power. If the under-knee prosthesis used by the disabled does not have toe joints, then the disabled will not only be unable to achieve many movements during exercise, but the gait will not be coordinated and natu...
