Abstract: An instrument guide is removably inserted into a proximal portion of a cannula and extends to a distal end of the cannula to guide and support multiple surgical instruments within the cannula. The instrument guide is designed to be manufactured by injection molding of plastic material. The instrument guide includes a tube and several radial walls connected to the tube to form passageways within the tube. The radial walls are joined to a core where they intersect. The tube and radial walls have substantially the same wall thickness and the core has a minimum diameter that is substantially larger than the wall thickness to facilitate delivery of plastic material. Portions of the tube and radial walls are thinner than the general wall and rib thickness to form guideways that support surgical instruments within the passageways. Channels may be formed on an outside of the tube to deliver insufflation gas.
