Abstract
A surgical retention port particularly useful as an arthroscopic port for shoulder surgery is provided. The surgical retention port has an inner cannula defining a throughbore, a plurality of rotatable fingers coupled to the inner cannula, and an outer cannula extending around the inner cannula. Rotation of the inner cannula relative to the outer cannula causes the rotation of the fingers from a first position where the fingers assume a collapsed configuration to a second position where the fingers assume an extended or open configuration.
