Abstract:
1. An optical penetrating system for permitting visualization, which comprises: a surgical portal having at least one seal for maintaining insufflation pressure in the abdominal cavity; an adapter member defining a longitudinal axis and having a proximal end, a distal end, and a transparent window adapted to penetrate tissue, the transparent window being adapted to permit visualization therethrough, the transparent window including an arcuate nose defining an apex, a pair of opposed first surfaces having a generally planar configuration and extending contiguously from the arcuate nose and arranged at a first oblique angle relative to the adapter axis, and a pair of opposed second surfaces having a generally planar configuration and positioned proximally of the pair of opposed first surfaces and extending contiguously therefrom in a proximal direction, wherein the pair of opposed first surfaces intersect the arcuate nose along a first line of intersection extending obliquely in relation to the longitudinal axis of the adapter member, and the pair of opposed second surfaces intersect the pair of opposed first surfaces along a second line of intersection extending obliquely in relation to the longitudinal axis of the adapter member, the first and second lines of intersection being substantially parallel in relation to each other, the pair of opposed second surfaces being arranged at a second oblique angle greater than the first oblique angle relative to the adapter axis; and means for coupling the adapter member to the surgical portal.
