Reusable superelastic iris retractor. The Microsurgery Advanced Design Laboratory.

摘要

We report the development and testing of a new reusable iris retractor for surgical dilatation of the pupil. The iris retractor is composed of superelastic nitinol (nickel-titanium alloy) which can be repeatedly flexed. The reusable superelastic iris retractor is a valuable new device for temporary mechanical dilation of the pupil. Its mechanical properties have proven its effectiveness as a reliable device for repeated clinical use.
