ABSTRACT:
Disclosed herein is a set of retractors which are coupled by releaseable locks to rods on the side of an operating table. A foot pedal is provided to release the locks and allow the retractors to be repositioned easily and with one hand by the doctor while performing the surgery. The foot pedal may utilize hydraulic fluid to lock or release the movement of the retractors. The joint holding the retractors is also rendered free to rotate to properly position the retractors, when the foot pedal is depressed.
