Abstract

A prosthetic socket system includes a prosthetic lock assembly having a lock body defining a pin hole adapted to receive an attachment pin, and a locking device in the lock body. The locking device is engageable with the attachment pin to unidirectionally lock the attachment pin in the lock body while permitting insertion of the attachment pin in the lock body. A valve assembly is positioned in the lock body that is movable between a closed position and an open position in which the valve assembly is unsealed so that air moves into the lock body via the valve assembly. A release mechanism positioned in the lock body is arranged to both release the locking device from the attachment pin and move the valve assembly to the open position by translating the locking device in the lock body.
