Abstract
Abstract A cannula ( 10 ) receives surgical instruments ( 120 ) for performing a surgical procedure on a body ( 130 ). The cannula ( 10 ) comprises a tube structure ( 12 ) defining a passage ( 16 ) through which the surgical instruments ( 120 ) are inserted into the body ( 130 ). The tube structure ( 12 ) has a proximal end ( 20 ) and a distal end ( 62 ). The tube structure ( 12 ) includes an expandable portion ( 40 ) for enabling an increase in the cross-sectional area of the passage ( 16 ) at the distal end ( 62 ). The expandable portion ( 40 ) of the tube structure ( 12 ), when expanded, has a conical configuration.
