Extending the usefulness of self-retaining retraction

Self-retaining retractors are a great aid in surgery since they assist in obtaining and maintaining the exposure necessary to accomplish the goal of surgery. The purpose of this retractor-retaining ring and clamp set is to increase the versatility of the self-retaining retractor and to make its advantages more generally available by a drastic reduction in cost. This is accomplished by using a simple, easily obtained clamp that can be adapted to the retractors presently available in any operating suite in combination with any of the three ring sizes to produce a self-retaining retractor that can easily accommodate variables such as the size of the patient and the type of operation.
