Abstract

Various universal ports for installation into a colon are disclosed. Some embodiments include means for permitting an anvil of a surgical stapler to pass through a port in a first direction and means for permitting a portion of the patient's colon to pass through the port in a second direction. Some embodiments also employ a flexible sleeve that may extend from the port out through the anus to provide a passageway for passing surgical instruments into and out of the rectum and also for removing severed specimens therefrom.
