A mouth gag device

Abstract

The application is suitable for the field of medical devices, and provides a mouth opening and jaw supporting device, which comprises a main body, a maxillary mouth opener arranged on the main body and used for supporting a maxilla, a mandibular mouth opener which is slidably connected to the main body and used for supporting a mandible, wherein the maxillary mouth opener is located on a sliding track of the mandibular mouth opener, an adjusting unit arranged on the main body and used for limiting the mandibular mouth opener, a tongue pressing rod arranged on the main body, and a jaw supporting plate arranged on the main body. When the mouth opening and jaw supporting device is used, the mouth of a patient is opened by the maxillary mouth opener and the mandibular mouth opener, the tongue of the patient is pressed by the tongue pressing rod, and the lateral mandibular gland of the patient is supported by the jaw supporting plate. In the process of a submaxillary duct stone removal operation, the number of surgical assistants is reduced, so that the submaxillary duct stone removal operation can be completed by fewer people.
