摘要：
The invention is directed to a bladeless trocar and obturator combination configured to separate body tissue. In one aspect, the obturator of the invention includes a rigid shaft extending along an axis between a proximal end and a closed, tapered distal end. The bladeless, closed and tapered tip is adapted to penetrate tissue. The shaft is sized and configured to receive an optical instrument having a distal end to receive an image of the body tissue. The shaft includes an ledge on the inner surface to provide proper positioning of the distal end of the optical instrument. The tapered configuration facilitates separation of different layers of the body tissue and provides proper alignment of the tip between the layers.
