ABSTRACT:
The present invention provides an obturator tip having a rigid, elongated, distal section having a blunt, rounded, distal end designed to separate tissue. The distal section is connected to a proximal section by a central section having tapered outer surfaces. The obturator tip of the present invention is equipped with arc shaped blades positioned on opposite sides of the tip and 180 degrees apart from each other. In one embodiment, the arc shaped blades are positioned rearwardly with respect to the distal section of the obturator. This feature of the present invention allows the elongated distal section to create a small, non-cutting tissue separating track prior to blade contact with the patient.
