An optical trocar system that includes an elongated obturator member having a first diameter. The elongated obturator member has a distal region, the distal region having a first diameter section having a diameter that is substantially equal to the first diameter of the elongated obturator member. The elongated obturator member has a second diameter section having a diameter that is less than the first diameter. The optical trocar system also includes an optical member attached to the distal region of the elongated obturator member such that the optical member encapsulates the second diameter section of the elongated obturator member and at least a portion of the first diameter section. A longitudinal bore through the elongated tubular obturator member is configured to receive an endoscope. |
