Patent ID: 7887483

Claim:
A safe surgical mouth gag (MG) comprising a substantially planar frame larger than the maximal mouth aperture which is defined by at least two cross members, being 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, said modules are selected from: a. a tongue blade having an elongated shaft approximately perpendicular to said frames' plane, which is vertically displaceable with respect to said mandibular cross member; b. a retaining member within which said tongue blade shaft is slidably displaceable, adapted for reversibly retaining said tongue blade at a predetermined vertical distance with respect to said mandibular cross member; said mandibular cross member and the entire frame is rotatable with respect to said retaining member; c. retraction elements for urging the cheeks away from the oral cavity; the said are pivotally maneuverable about said maxillary cross member and are laterally displaceable; d. abutment members for contacting the upper teeth or upper maxilla, pivotally maneuverable about said maxillary cross member and are laterally displaceable; and, e. at least one light auxiliary located adjacent to oral cavity, adapted to illuminate the same effectively; such as a prompt removal of the MG from the oral cavity is ensured, also in an emergency removal procedures, individually set and adjusted for each patient and the existing devices and their parts are difficult or in some cases impossible to manipulate; wherein the retaining member comprises an inwardly facing track within which the tongue blade shaft is slidably displacement; an outwardly facing concave seat for receiving each corresponding elliptical element; a locking assembly for preventing the rotation of the maxillary cross member; and means for setting the vertical distance between the tongue blade and the mandibular cross member.
