Abstract
A surgical scalpel has a retractable sleeve. An elongated handle with a contoured grip portion is releasably attached to a blade holder securing a surgical blade. The blade holder is secured to the handle by a hook and groove assembly and a male to female connection. The sleeve slides between an extended position and a retracted position on the handle and blade holder. The extended position of the sleeve covers the blade thereby protecting operating room personnel. An arch on the sleeve contacts the hook and disengages the hook out of the groove to facilitate removal of the blade holder.
