<p>A trocar assembly is disclosed which includes a shank having a distal end and a proximal end, and a planar piercing blade having two substantially flat faces and a cutting contour, where the piercing blade is integrally attached to the distal end of the shank. The shank tapers inwardly towards said opposed flat faces of said piercing blade. A trocar tip protector may be disclosed that is housed within the shank and adapted to actuate between a retracted and an extended position where an actuator mechanism causes the tip protector to move to the extended position covering the blade when the tip of the trocar member has entered the patient's body cavity. A tip protector indicator is also disclosed that provides a visual indication of whether the tip protector is in the retracted or extended position.</p> |
