ABSTRACT:
A trocar adapted to provide a working channel through a body wall and includes a cannula defining the channel along an axis between the distal and proximal ends of the cannula. A housing disposed at the proximal end of the cannula includes at least one elastomeric seal. An elongate obturator adapted to be moved in proximity to the seal includes a sharp distal tip and a sheath which protects the seal from the sharp tip during movement of the obturator through the working channel. This sheath is movable from a first position wherein it is releasably fixed to the obturator and a second position wherein it is releasably fixed to the housing to expose the shape tip distally of the cannula.
