ABSTRACT:
A safety penetrating instrument for establishing a portal in an anatomical cavity for performing endoscopic procedures includes a penetrating member received within a distally biased portal sleeve for introducing the portal sleeve through a cavity wall into the anatomical cavity, the portal sleeve having a distal end movable between an extended position protecting a sharp tip of the penetrating member and a retracted position exposing the sharp tip. A handle is provided manually moving the portal sleeve to the retracted position, and a locking and releasing mechanism locks the portal sleeve in the retracted position and releases the portal sleeve to return to the extended position in response to distal movement of an operating member upon penetration of the safety penetrating instrument into the anatomical cavity, the operating member being preferably carried by the penetrating member.
