Two stage releasing interlocking system

摘要

A two stage releasing interlocking system for mounting a medical device tool which includes a jaw head having an aperture. A collet having an upper portion and a lower portion is rotatably mounted within the jaw head. The upper portion of the collet has an aperture and is substantially aligned with the aperture of the jaw head. A moving means moves the lower portion of the collet into an opened position and a closed position with respect to the upper portion of the collet. Actuating means prevents the moving means from moving the lower portion of the collet into the opened position when the actuating means is in a first position and permits the moving means to move the lower portion of the collet into the opened position when the actuating means is in a second position.
