Claim 0:
1. A handheld body cavity access device, the device comprising:
a handle including a distal end, a proximal end, and a longitudinal axis extending between the distal and proximal ends, the handle having a cavity aligned with the longitudinal axis;
a trocar including a proximal end coupled to the handle;
a dilator assembly at least partially disposed within the trocar and having a distal end and a dilator hub at least partially disposed in the cavity of the handle, the dilator hub including a tubular portion and a flange extending radially outward from the tubular portion;
a blade assembly at least partially disposed within the dilator assembly;
a spring disposed in the cavity of the handle and biased against the dilator hub;
wherein the dilator assembly is movable between a retracted position, in which a distal end of the blade assembly extends from the distal end of the dilator assembly and the spring is in a compressed position, and an extended position, in which the distal end of the blade assembly is covered by the distal end of the dilator assembly and the spring is in an expanded position;
wherein the spring engages a spring seat defined by an outer surface of the flange of the dilator hub,
the device further comprising a needle assembly coupled to the handle by a lock so that when the needle assembly is in a locked position, the needle and handle are movable together, and when the needle assembly is in an unlocked position, the handle is movable axially relative to the needle.
