Abstract
The present invention discloses a safe surgical mouth gag (MG) having a substantially planar frame larger than the maximal mouth aperture which is defined by at least two cross members, i.e., a longitudinal maxillary cross member and a mandibular cross member and by at least one rod connecting said maxillary and said mandibular cross members; and modules maneuverably interconnected to the same. The modules are selected from a tongue blade approximately perpendicular to the frames' plane, which is vertically displaceable with respect to said mandibular cross member; a retaining member within which said tongue blade shaft is slidably displaceable; retraction elements for urging the cheeks away from the oral cavity; abutment members for contacting the upper teeth or upper maxilla; and at least one light auxiliary located adjacent to oral cavity, adapted to illuminate the same effectively.
