ABSTRACT:
A safety surgical instrument having a sheath, a handle, a surgical element such as a blade or needle, and a manner for moving the surgical element out of and into the sheath by rotary and longitudinal movement of the handle. The control of the movement of the surgical element is accomplished with an insert within the sheath that provides a groove path for cooperation with a part of the handle to move the surgical element in response to rotary and longitudinal movement of the handle. The handle rotary movement is in one direction only to place the surgical element in an unsheathed stop postion and in a sheathed stop position.
