ABSTRACT:
A safety needle includes an elongate tubular needle and safety probe movable therein between an extended position with a blunt distal end of the safety probe projecting distally of the needle distal end and a retracted position with the safety probe distal end disposed proximally of the needle distal end. In one embodiment, the safety probe forms a protective recess for receiving the sharp tip of the needle in the extended position. In another embodiment, the needle distal end has a peripheral edge disposed in a plane positioned at an acute angle relative to the longitudinal axis of the needle, and the safety probe has a distal end surface disposed in substantially the same plane as the distal end of the needle during penetration through tissue. In a further embodiment, the needle has a portion curving toward the longitudinal axis of the needle to terminate at the sharp tip. A pin and slot locking mechanism allows selective, releasable locking of the safety probe in the retracted and/or extended positions and manual movement of the safety probe in the needle.
