ENTRY GUIDE FOR MULTIPLE INSTRUMENTS IN A SINGLE PORT SURGICAL SYSTEM

A surgical access port comprises a cannula comprising a proximal portion and a distal portion comprising a flexible section. The access port further comprises an instrument guide configured to be positioned within the cannula. The instrument guide comprises a proximal end, a distal end, and a plurality of instrument guide channels between the proximal and distal ends of the instrument guide. Each instrument guide channel of the plurality of instrument guide channels defines a corresponding guide channel opening. An outside surface of the instrument guide fits closely to an inner wall surface of the cannula when the instrument guide is within the cannula. A guide channel opening of a first instrument guide channel of the plurality of instrument guide channels is open to the outside surface of the instrument guide.
