Abstract
An adjustable surgical retractor clamping mechanism for attaching mechanism to an operating table. The mechanism includes an upper jaw, lower jaw, a drive member, an adjustable frame support post and a releasable clamp for adjusting the height of the surgical retracting frame. The upper portion of the lower jaw has a plurality of slots cut into the sidewalls of upper jaw to form at least one flexible finger. The clamp is in close sliding relationship to the upper portion of lower jaw member. The clamp includes a cam lever. Movement of the cam lever to its closed position compresses the clamp causing the flexible fingers to grip the adjustable post locking its longitudinal movement. Rotation of the cam lever to the open position releases the compressive force on the clamp, unlocking the adjustable post allowing the post to be longitudinally adjusted relative to the clamping mechanism.
