Claim:
1. An apparatus for introducing a bone portal into a bone of a subject, the apparatus comprising: a handle; a base detachably coupled to the handle by a mechanism comprising a base coupling, a driving member projecting from a carrier assembly that is slidably received within the handle; a ratchet operatively coupled between the carrier assembly and the handle, the ratchet oriented to permit the carrier assembly to move toward a distal end of the handle and to resist motion of the carrier assembly away from the distal end of the handle; and, a release mechanism operative to block the carrier assembly from moving toward the distal end of the handle until the release mechanism is triggered; wherein the driving member is movable between a first position wherein the driving member is retracted behind the base to a second position wherein the driving member projects past the base by operating the handle and the base is detachable from the handle by release of the base coupling, wherein the base coupling comprises an actuating member arranged so that operation of the handle to move the driving member to its second position results in the actuating member being moved to uncouple the base from the handle.
