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 in active and passive movement modes. Background technique [0002] With the increase of various natural disasters, diseases and traffic accidents, the number of disabled people is increasing year by year, and the demand for artificial limbs is also increasing. The toe joint is the most active part of the human body, and it is also the main stress-bearing part during exercise. It is especially the first part to touch the ground when the human body falls to the ground. flexible power. If the below-knee prosthesis used by the disabled does not have toe joints, the disabled will not only be unable to perform many actions during exercise, but also have an uncoordinated and natural gait, which also reduces energy efficiency during walking. In order to improve energy efficiency during exercise and increase the variety and ...
