ABSTRACT:
An obturator (2) includes a hollow housing (4) with an obturator barrel (6) extending therefrom. The tip (172) of the obturator has a cutting element (40) and a safety shield (46). The safety shield is automatically rotatable from a cutting position, with the blade exposed, to a safe position, with the blade shielded, when the blade has passed through the tissue layer being pierced. The safety shield can be returned to the cutting position using a rearming device (128, 274) mounted to the housing at the proximal end of the obturator. The obturator barrel (6a) can be bent for use.
