ABSTRACT:
A surgical instrument for performing procedures such as carpal tunnel release. The instrument consists of an elongated member having a spring or cam plate positioned therein. The spring or cam plate is movable from a retracted position within the elongated member to an extended position protruding through an aperture in the elongated member. Movement of the spring or cam plate to the extended position stretches a flexible membrane positioned over at least a portion of the elongated member to stretch the carpal tunnel ligament.
