Abstract

A limb restraint permits proper positioning of a limb of a patient while medical or surgical operations are being performed on the patient. The preferred embodiment includes a fixed restraint and an adjustable restraint which cooperate with each other to encircle the limb and hold it in place. One end of the adjustable restraint can be wound around or unwound from a spool using a handle assembly to tighten or loosen, respectively, the restraint on the limb. A clutch is provided to prevent the spool from rotating in a direction that would loosen the restraint. The handle assembly used to tighten or loosen the restraint prevents inadvertent tightening or loosening of the restraint when the handle assembly is not in use.
