ABSTRACT:
A safety penetrating instrument for penetrating an anatomical cavity wall to gain access to an anatomical cavity includes a penetrating member having a distal end for penetrating the anatomical cavity wall, a distally-biased safety member having a distal end movable between an extended position where the safety member distal end protrudes distally from the penetrating member distal end to protect the distal end of the penetrating member and a retracted position where the safety member distal end is disposed proximally of the penetrating member distal end to expose the penetrating member distal end, an extending mechanism for moving the safety member to the extended position and for permitting the safety member to move proximally toward the retracted position, a handle or the like for manually moving the safety member proximally to the retracted position and a lock for locking the safety member in the retracted position to prevent movement of the safety member to the extended position during penetration of the anatomical cavity wall. The safety member can be a cannula, safety shield or probe, or both a cannula and safety shield or probe, movable proximally from the retracted position during penetration of the anatomical cavity wall and distally toward the retracted position in response to introduction in the anatomical cavity. The safety penetrating instrument is responsive to movement of the cannula and/or the safety shield or probe distally toward retracted or rest positions to trigger release of the lock to permit the extending mechanism to move the safety member to the extended position.
