Description

Technical Field

[0001] The invention relates to an oral opening device. Background Art

[0002] An oral opener (also called a mouth opener or mouth gag) is a medical device that is mainly used to keep the patient's mouth open during examination or treatment to ensure operating space and field of view. During dental examination and treatment, a pliers-type mouth opener is often used to keep the patient's mouth open. The structure of the pliers-type mouth opener can be found in Chinese patent CN201920516795.X. It is usually made of metal material with a hard texture. During actual use, its pliers arms are in direct contact with the facial skin and the inside of the mouth. This way of use will cause discomfort to the patient, and bruises are likely to occur at the corners of the patient's mouth due to the pulling of the pliers arms. The patient's gums and the inside of the mouth are also easily scratched or crushed by the dental plate and flange plate. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an oral opener, which protects the corners of the patient's mouth when using the existing pliers-type opener through an external silicone pad that is flexibly connected to the opener body to prevent bruising. In addition, a covering structure is provided on the tooth plate and flange plate of the existing pliers-type opener to prevent the patient's gums and the inside of the mouth from being easily scratched or crushed by the tooth plate and flange plate.

[0004] In order to solve the above technical problems, the present invention provides an oral opener, including an opener body, the opener body including a left plier arm and a right plier arm both of which are arranged vertically and symmetrically on the left and right sides, the left plier arm and the right plier arm both including a plier head and a plier handle arranged up and down and integrally formed, the plier head and the plier handle of the left plier arm and the right plier arm are hinged at the junction through an articulated shaft with an axial direction running forward and backward, an opening angle adjustment limit device composed of a limiting tooth groove mechanism and a spring is provided between the plier handles of the left plier arm and the right plier arm, and a plier head on the upper side of the left plier arm and the right plier arm is provided with a rearward The inverted U-shaped extension part, the rear end of each extension part is connected to a long strip of dental support plate, the dental support plate is provided with anti-slip notches, each dental support plate is provided with symmetrically arranged flange plates on both sides in the width direction, the rear end of the hinge shaft is embedded with a first snap buckle female buckle, and the two sides of each flange plate are embedded with a second snap buckle female buckle, and also include a dedicated external silicone pad, the silicone pad is roughly an isosceles triangle, and the two bottom corners of the isosceles triangle of the silicone pad are provided with a laterally extending long strip extension pad, and the silicone pad and the extension pad are in the thickness direction. The sides are flush with each other, and the length direction of the extension pad is parallel to the bottom side of the isosceles triangle of the silicone pad. One side of the silicone pad along its thickness direction is named A side, and the other side is named B side. The male buckle of the first snap button is embedded at the top corner of the isosceles triangle of the silicone pad on the position of the A side. The male buckles of four second snap buttons are provided on each extension pad at the position of the A side. The four male buckles of the second snap buttons on each extension pad are spaced apart along the length direction of the extension pad. The side close to the silicone pad along the length direction of any extension pad is set as the inner side, and the side away from the silicone pad is set as the outer side. One side is the outside, and the four second snap buttons on any extension pad are numbered in order from the inside to the outside, namely the first male button, the second male button, the third male button, and the fourth male button. The spacing distance between the first male button and the second male button is consistent with the spacing distance between the third male button and the fourth male button, and both are smaller than the spacing distance between the second male button and the third male button. A first thickened silicone convex hull is provided on the B surface at a position corresponding to the bottom edge of the isosceles triangle of the silicone pad, and a second thickened silicone convex hull is provided on the B surface at a position corresponding to any second male button and the third male button.

[0005] The method of using the present invention is as follows: when in use, the male buckle of the first snap button is matched and fastened with the female buckle of the first snap button, and then the high line of the isosceles triangle of the silicone pad is laid along the inner edge of the inverted U-shaped extension part of the opener body, and then the A surfaces of the two extension pads are respectively laid in contact with the corresponding tooth tray and flange plate surfaces, so that the extension pads completely wrap the scored surface of the tooth tray and the two side surfaces of the flange plate, and then the first male buckle, the second male buckle, the third male buckle, and the fourth male buckle of the A surface of the extension pad are respectively matched and fastened with the four female buckles of the second snap buttons on the corresponding two flange plates.

[0006] Advantages of the present invention: The present invention provides an opener body and a special external silicone pad. The opener body is embedded with a female snap button on the basis of a traditional pliers-type opener. The external silicone pad is flexibly connected to the opener body by setting a corresponding male snap button. The opener body and the special external silicone pad are put into use after being connected. The position of the first thickened silicone convex bulge just contacts the corner of the patient's mouth on that side. The first thickened silicone convex bulge can protect the corner of the patient's mouth, alleviate the pulling feeling at the corner of the mouth, reduce the patient's discomfort and prevent bruises at the corner of the mouth. The two extension pads The tooth tray and flange plates on the corresponding sides are wrapped to prevent the patient's gums and the inside of the mouth from being scratched or crushed by the tooth tray and flange plates. The second thickened silicone bulge is just located on the notched surface of the tooth tray, which can also protect the teeth from being scratched and increase the friction, making the use of the mouth opener more stable. In addition, the external silicone pad in the present invention is a consumable material and can be quickly replaced after each use. The operation is simple and convenient, and the mouth opener body can be rotated for use after disinfection. Compared with the existing mouth openers, it does not increase the use cost a lot and is suitable for promotion within the industry. BRIEF DESCRIPTION OF THE DRAWINGS
