An optical obturator system is described. The optical obturator system includes a transparent window member provided on a distal tip portion of the obturator shaft, thus permitting the surgeon to visualize the tissue of the patient (e.g., via an imaging system positioned near the window member). One or more major portions of the optical obturator system may be formed of a biocompatible material, such as but not limited to stainless steel. Accordingly, the optical obturator system may be reusable for a relatively large number of surgical procedures.

A cannula system is described. The cannula system may be formed of biocompatible materials that are suitable to be sterilized. Accordingly, the cannula system may be reusable for a relatively large number of surgical procedures assuming conventional sterilization techniques are employed after each surgical procedure. Additionally, the cannula system may be provided with an internal valve system disposed in a port portion thereof wherein the valve system may be operable to receive the trocar there through, as well as maintaining insufflation of the body cavity. Furthermore, the cannula system may be provided with a plurality of rib members formed on an external surface of the cannula shaft, wherein the rib members may engage the tissues adjacent the incision, thus maintaining the position of the cannula shaft and reducing and/or lessening relative movement of the cannula shaft.

A trocar is described. The trocar is formed of a biocompatible material, such as but not limited to stainless steel. Accordingly, the trocar is reusable for a relatively large number of surgical procedures assuming conventional sterilization techniques are employed after each surgical procedure. Additionally, the trocar is provided with an angled blade design formed on a distal portion of the trocar shaft. More specifically, the blade design includes a first portion extending substantially co-planar to a proximal portion of the tip portion of the trocar shaft and a second portion extending angularly inwardly towards a distal portion of the tip portion of the trocar shaft.
