ABSTRACT:
During back surgery, a surgeon can, with one hand, apply traction against tissue in a surgical wound by using a retraction device that includes an upstanding post and a surgical retractor, the handle of which is formed with ratchet teeth for securing the retractor to the post against elastic recoil of the retracted tissue. The post preferably is integral with a slip-lock which can be slidably mounted on a rectangular rail of a framework that extends above the patient. The slip-lock includes a floating jaw that is loosely pinned to a slide and becomes releasably locked to the rail when the elastic recoil of retracted tissue pulls on the post. Because the retraction device holds the tissue precisely in the position to which it is set by the surgeon, the hazards involved in using assistants to hold retractors are avoided.
