Abstract The present invention relates to retractors generally, and more specifically to oral retractors for use in conjunction with the administration of anesthesia, as well as for use in conjunction with the performance of other surgical and dental procedures. More specifically, the invention comprises a flat metal strip having one end thereof formed into a tapered hook for insertion into the patient's mouth. The strip is bent or formed intermediate its ends so as to cause the end remote from the hook to project downwardly and in an essentially parallel relation with respect to the tapered hook end. A weight is secured to the end remote from the hook, whereby the lips are retracted upon placement of the instrument properly in the patient's mouth to thereby permit the physician to work in the area proximate the hook without interference from the patient's lip or from the instrument itself.
