Abstract

At the suggestion of Dr. Loyal Davis, I have designed several instruments made of molded methyl methacrylate resin (lucites®) for use in neurosurgical operations. These include brain retractors, S-retractors, spoons, and a small mallet (fig. 1, 2, and 3). Lucite® is available in transparent sheets in a variety of thicknesses, 0.06 to 0.25 in. (0.15 to 0.64 cm.). I have found the 0.125 in. (0.32 cm.) thickness to be the most desirable for making the retractors and spoons. Lucite® is also obtainable in cylinders, which were used in making the mallet.

The patterns for the retractors and spoons were initially cut from the sheets of lucite® with a band or jig saw, much as such patterns would be cut from plywood. Since lucite® becomes soft and is easily molded when heated, these patterns were heated and then molded into the desired shapes. The brain retractors
