Abstract

A prosthetic attachment system includes an insert arranged for connection to a prosthetic liner, and an attachment unit arranged for connection to a distal end of a prosthetic socket. The attachment unit comprises a body defining an axis and a central opening for selectively receiving the insert. The body carries a plurality of locking elements that are distributed circumferentially about the axis and radially repositionable relative to the axis. A release mechanism is slidably positioned on an outer surface of the body to move the prosthetic attachment system between a locked configuration in which the locking elements are radially repositioned to lock the insert in the central opening of the body and an unlocked configuration in which the insert is released from the central opening.
