ABSTRACT:
A cannula assembly for use in laparoscopic surgery comprises a rigid tubular member and a first component connected to the tubular member and rigid therewith for defining, for a first laparoscopic instrument having a rigid shaft, a first insertion path through the tubular member and through a pre-established instrument-crossing region of predetermined area to be lodged in a patient's abdomen. A second component is connected to the tubular member and is at least partially separate from the first component for defining, for a second laparoscopic instrument having a rigid shaft, a second insertion path through the instrument-crossing region.
