Abstract

The invention relates to a power below-knee prosthesis with discrete soft toe joints. The power below-knee prosthesis with discrete soft toe joints is characterized in that the power below-knee prosthesis comprises an integrated foot plate, a toe joint and a below-knee prosthesis; the toe joint consists of a motor which is arranged on the integrated foot plate by a support, the motor is connected with a connecting bar by a driving mechanism, the other end of the connecting bar is hinged with a pressure block, the pressure block is hinged at the top surface of the front end of the integrated foot plate, and the below-knee prosthesis is fixedly connected or hinged at the top surface of the rear part of the integrated foot plate. The power below-knee prosthesis has the advantages of being good in movement continuity, being independently installed or replaced, and being capable of providing discrete soft power for movement of a crus of a user, and can be widely suitable for different degrees of amputated patients for use.

Description

technical field [0001] The invention relates to an under-knee prosthesis, in particular to a dynamic under-knee prosthesis with discrete 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 na...
