ABSTRACT:
A safety penetrating instrument for establishing a portal in the wall of an anatomical cavity includes a housing, a distally-biased portal sleeve movable proximally during penetration from an extended rest position to a retracted position, a penetrating member disposed within the portal sleeve and movable relative thereto between an extended position where a distal end of the penetrating member protrudes from the portal sleeve distal end and a retracted position where the penetrating member distal end is proximally spaced from the portal sleeve distal end, a retracting mechanism for moving the penetrating member from the penetrating member extended position to the penetrating member retracted position, a locking mechanism for locking the penetrating member in the penetrating member extended position while permitting a predetermined amount of proximal movement of the penetrating member during penetration of the anatomical cavity wall, a penetrating member bias member for biasing the penetrating member distally in the penetrating member extended position while permitting the penetrating member to move proximally during penetration of the anatomical cavity wall, and a releasing mechanism responsive to penetration of the anatomical cavity wall for triggering release of the locking mechanism to permit the retracting mechanism to move the penetrating member proximally to the penetrating member retracted position.
