ABSTRACT:
A trocar has an elongated body with a frustro-conical end which terminates in a blunt tip. A plurality of blades are radially attached to a blade housing connected to the trocar body. In one embodiment the blade housing moves toward the trocar body in response to a force causing the blades to extend to a cutting position. When the force is removed the blades return to a retracted position.
