Abstract
In an irrigation/aspiration, surgical instrument for intraocular eye surgery, an inner cannula provides aspiration while a larger, but coaxially-spaced outer cannula provides irrigation. The outer cannula is made of metal but is connected to the tip of the surgical instrument by a flexible, silicon rubber support so that the outer cannula is relatively flexible compared to the stiffness of the cannula. Thus the outer cannula can be rotated or repositioned without distortion since all of the motion is localized at the flexible support.
