Abstract
Abstract An automatic retractable safety penetrating instrument includes a sleeve for being introduced in a body cavity and a penetrating member disposed within the sleeve and having a sharp distal tip for penetrating a wall of the cavity. A retracting mechanism biases the penetrating member to a retracted position wherein the sharp distal tip is in a safe, protected position, and the penetrating member is movable distally from the retracted position to an extended position wherein the sharp distal tip extends beyond a distal end of the sleeve. The penetrating member is automatically locked against movement to the retracted position upon axial rotation of a locking and releasing mechanism in response to movement of the penetrating member to the extended position. An operating member is biased to move distally upon the sleeve distal end entering the body cavity such that the locking and releasing mechanism is axially rotated in response to distal movement of the operating member. Rotation of the locking and releasing mechanism upon the sleeve distal end entering the body cavity causes the penetrating member to be released for movement to the retracted position. Upon release of the penetrating member, the retracting mechanism automatically moves the penetrating member to the retracted position with the sharp distal tip in the safe, protected position. A method of establishing communication with an anatomical cavity utilizing an automatic retractable safety penetrating instrument including a sleeve and a penetrating member disposed in the sleeve includes the steps of forcing the automatic retractable safety penetrating instrument through tissue to enter the anatomical cavity and rotating a mechanism of the instrument about a longitudinal axis of the penetrating member to unlock the penetrating member causing movement of the penetrating member to a retracted position in response to entry of the automatic retractable safety penetrating instrument into the anatomical cavity.
