Abstract
A surgical access device comprising a tissue separating obturator suitable for connection with a cannula is disclosed. The obturator includes an elongate shaft having a transparent distal tip. The elongate shaft extends along a longitudinal axis and defines a lumen. The transparent distal tip has a tapered configuration and includes an inner surface and an outer surface adapted for penetrating tissue. The lumen is sized and configured to receive an optical instrument such as a laparoscope. The surgical access device further includes a scope lock at the proximal end of the shaft portion. The lock includes a multi-fingered collet coaxial with the lumen. The inner diameter of the collet is smaller than an outer diameter of the optical instrument and the fingers of the collet provide frictional engagement with the outer diameter of the optical instrument that is inserted into the lumen of the obturator.
