ABSTRACT:
An adjustable length cannula which may be longitudinally extended or retracted in order to accommodate a range of body cavity wall thicknesses. A method for inserting the cannula is disclosed, in which a guiding cannula is placed into the peritoneal cavity using the insufflation needle as a guidewire, and a screw dilator and cannula are then placed into the peritoneal cavity using the guiding cannula as a guidewire. The guiding cannula also allows visual inspection of the peritoneal cavity with an endoscope prior to insertion of the dilator/cannula in order to verify proper clearance.
