ABSTRACT:
The safety penetrating instrument includes a tubular needle having a distal end with a sharp tip, a safety probe movable within the needle between an extended position protecting the needle tip and a retracted position exposing the needle tip and is biased toward the extended position and a portal sleeve surrounding the needle to establish communication with an anatomical cavity with penetration of tissue surrounding the cavity by the needle. The needle distal end has a leading edge defining the sharp tip and a trailing edge and the portal sleeve has a distal edge disposed in substantial alignment with or forward of the trailing edge of the needle distal end. A locking mechanism automatically locks the safety probe in the extended position after the safety probe is returned thereto or can optionally allow locking of the safety probe or allow proximal movement of the safety probe after return to the extended position. The locking mechanism also provides selective locking of the safety probe in the retracted position.
