Abstract
A guide for a cannula extending through a tissue and into a cavity in which a surgical procedure is to be performed. The guide has first and second plates cooperatively defining a through passageway for a cannula. Structure connects between the first and second plates to allow selective altering of the relative positions of the first and second plates to thereby change the configuration of the through passageway defined cooperatively between the first and second plates. A conversion unit can be used to draw the plates away from each other to enlarge an incision into which the first and second plates extend.
