PROSTHETIC DEVICE USING A CAM-SHAPED WHEEL

摘要

A prosthetic device includes an energy storing member (26), a lever member (18) attached to the energy storing member, a rocking member (22), and an energy transfer line (28). This line has a first end (27) attached to a front end (28) of the energy storing member (26) and a second end (29) attached to a back end of the lever member. The line has its middle portion (39) attached to the rocking member (22). The energy storing member (26) is preferably a leaf spring. This combination of elements in the prosthetic device may be a lower leg or foot for use by a below-the-knee amputee to simulate more closely the natural gait of a person while walking or running.
