ABSTRACT:
A cannula is divided longitudinally into a camera chamber and an instrument passage. The distal end of the camera is sealed by an optically clear member. In use, a camera assembly which includes a camera sled on which are mounted a charge-coupled device camera and lights is inserted into the camera chamber and a conventional laparoscopic instrument is inserted into the patient through the instrument passage. The camera sled is isolated from the patient by the cannula, eliminating the need to sterilize the camera sled. The instrument is held in position by an attachment member which extends from the cannula. This allows the surgeon to control the position of the instrument and the camera with one hand. The cannula includes a port for connecting a source of CO.sub.2 to inflate the patient's abdominal cavity and a port for connecting a conventional suction/irrigation trumpet-valve assembly.
