Abstract: A detachable handle assembly for a tool, the tool for creating a sub-sternal tunnel in a patient. The handle assembly includes a lock-and-release mechanism by which the tunneling assembly is attached to the handle, the mechanism being operable to detach the handle from the tunneling assembly. The handle assembly also may include a knob that interlocks with the tunneling assembly, the knob being configured for engagement by fingers of an adult hand to apply a force to rotate a boring tip of the tunneling assembly.
