ABSTRACT:
A retractable safety penetrating instrument includes a cannula and a needle disposed within the cannula and supported in a manner to automatically move proximally from an extended position wherein a sharp distal end of the needle protrudes from the cannula to a retracted position wherein the sharp distal end of the needle is protected in response to distal movement of the retractable safety penetrating instrument upon penetration into a cavity in the body. A retracting mechanism moves the needle proximally, is normally locked in a position preventing proximal movement of the needle and is released by distal movement of an operating member to trigger retraction of the needle.
