Document Type and Number:
Japanese Patent JP3564139
Kind Code:
B2
Abstract:
An access port for use in surgery comprises an elongate sleeve (2) of flexible material having an entry opening (7) located at a proximal end (3) of the sleeve (2) and an exit opening located at a distal end (4) of said sleeve. An inflatable chamber (46) surrounds the sleeve (2) and extends substantially coaxially therewith from the proximal end (3) of the sleeve for a distance along the length of said sleeve. The inflatable chamber (46) when inflated operates to collapse the sleeve (2) to close the entry opening (7). The sleeve (2) is attached to and surrounded by the inflatable chamber (46) with the sleeve (2) extending through the inflatable chamber (46) and outwardly therefrom to provide a projecting flexible sleeve portion (41) extending outwardly from the inflatable chamber (46) to the exit opening at the distal end of said sleeve. The projecting sleeve portion (41) can be inserted through an incision and into a patient's body cavity to provide a flexible sleeve portion adjacent to the exit opening within the body cavity free of a surrounding inflatable chamber.
