PROSTHETIC FOOT WITH PROGRAMMABLE MOVEMENT

摘要

A programmable prosthetic foot includes a heel member simulating a heel portion of a human foot. The heel member has an elongated heel member shaft extending in a vertical direction. The foot also includes a forefoot member simulating a forefoot portion of a human foot. The forefoot member has an elongated forefoot member shaft extending in the vertical direction. A sensor on the foot detects compressive force on the heel member shaft and/or forefoot member shaft during a step. An actuator on the foot imparts vertical translation to the heel member shaft and/or forefoot member shaft. An electronic controller in operable communication with the actuator includes program instructions for operating the actuator by imparting the vertical translation to the heel member shaft and/or forefoot member shaft as a function of the compressive force detected by the sensor.

1. A prosthetic foot comprising:
a heel member simulating a heel portion of a human foot, the heel member including an elongated heel member shaft extending in a vertical direction; a forefoot member simulating a forefoot portion of a human foot, the forefoot member including an elongated forefoot member shaft extending in the vertical direction; a sensor that can detect compressive force on the heel member shaft and/or forefoot member shaft during a step; an actuator that can impart vertical translation to the heel member shaft and/or forefoot member shaft; and an electronic controller in operable communication with the actuator, the electronic controller including program instructions for operating the actuator by imparting the vertical translation to the heel member shaft and/or forefoot member shaft as a function of the compressive force detected by the sensor.
