Description

Technical Field

[0001] The utility model belongs to the field of oral opening devices. Background Art

[0002] In oral surgery, the operating space and operating field of view are limited, especially when performing oral surgery under general anesthesia. The patient loses all autonomy in opening his mouth, and the operating space and operating field of view are further reduced. Therefore, an oral opener is needed to expand the mouth in order to achieve the purpose of expanding the operating space and operating field of view. However, traditional oral openers have some shortcomings.

[0003] Existing oral openers can only open the corners of the mouth, exposing only the front teeth and the teeth near the front teeth, but not the molars on the sides. When doctors treat the molars on the sides of patients, the operating space is small, the field of vision is limited, and the teeth will be soaked by the constantly flowing saliva, affecting the doctor's treatment. If the tongue depressor or instrument is used to forcibly lower the mandible and open the bite, the user will be tired during the operation, which will affect the operation during the operation and increase the risk. At the same time, it is inconvenient to position and fix. It is also extremely uncomfortable for patients to wear, and even causes damage to tissues. There is also a lighting shadow area in the mouth, which requires additional equipment for lighting, making the use of the mouth opener inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide a mouth opener, which has the advantages of reducing doctor's fatigue, convenient positioning and fixing, good wearing comfort and convenient use.

[0005] The technical solution of the utility model is as follows: an oral opener comprises a frame, a soft rubber layer is arranged on the outer side of the frame, the frame comprises a pipeline, the pipeline comprises an intermediate tube, a suction port is arranged on the bottom of the intermediate tube and penetrates downwardly through the soft rubber layer, a vertical tongue depressor is arranged on the intermediate tube, the tongue depressor corresponds to the back of the tongue in the oral cavity, side tubes are arranged at both ends of the intermediate tube, the side tubes correspond to the inner walls on both sides of the oral cavity horizontally, extension tubes are arranged at the outer ends of the side tubes, one end of the extension tube is closed, and the other end of the extension tube is open.

[0006] In the aforementioned oral opener, a lighting lamp is provided on the tongue depressor or the middle tube, and a USB power supply interface connected to the lighting lamp is provided on the extension tube with a closed end.

[0007] In the aforementioned oral opener, the lighting lamp is an LED lamp.

[0008] In the aforementioned oral opener, a pagoda joint is provided at the end of the open-ended extension tube.

[0009] In the aforementioned oral opening device, the two extension tubes extend outwardly at an angle, so that an eight-shaped structure is formed between the two extension tubes.

[0010] In the aforementioned oral opener, a side lip embedded plate is provided at the connection between the middle tube and the extension tube. The side lip embedded plate corresponds to the corners of the mouth on both sides of the mouth. The middle part of the side lip embedded plate is fixed to the pipe. The upper and lower ends of the side lip embedded plate are bent inward, and the front and rear sides of the side lip embedded plate are bent outward, so that the outer side of the side lip embedded plate forms a groove that matches the lips of the mouth.

[0011] In the aforementioned oral opening device, the connection between the middle tube and the side tube forms an occlusal position corresponding to the position of the molars inside the oral cavity.

[0012] In the aforementioned oral opening device, the middle portion of the intermediate tube protrudes inwardly, so that the middle portion of the intermediate tube is away from the uvula of the oral cavity.

[0013] Compared with the prior art, the utility model sets a tongue depressor in the middle of the pipe to limit the range of movement of the tongue, so that the molars are fully exposed, and the tongue depressor is integrated with the mouth opener, so the doctor does not need to operate the tongue depressor additionally, which reduces the doctor's fatigue and reduces the treatment risk. Through the occlusal position on the pipe, the mouth opener is hooked by the molars in the front and back directions, and the side lip embedded plate is used to fix and position the mouth opener by the lips, so that the positioning and fixing of the mouth opener are convenient. Since the shape of the side lip embedded plate can match the shape of the mouth when it is open, and the contact area is large, the patient is more comfortable to wear and avoids tissue damage. By pre-installing a lighting lamp on the mouth opener to illuminate the oral cavity, the doctor does not need to use additional equipment for lighting, and it is convenient to use. Therefore, the utility model has the advantages of reducing the doctor's fatigue, convenient positioning and fixing, better wearing comfort and more convenient use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0021] Embodiment. A mouth opening device, such as Figure 1 As shown, it includes a frame, and a soft rubber layer 1 is provided on the outer side of the frame. The soft rubber layer 1 is made of medical silicone.

[0022] The skeleton includes a pipeline, and the pipeline includes an intermediate tube 2. The bottom of the intermediate tube 2 is provided with a suction port 12 that penetrates downward through the soft rubber layer 1. The intermediate tube 2 is provided with a vertical tongue depressor 3, which is fixed to the rear side of the intermediate tube 2. The tongue depressor 3 corresponds to the tongue root position of the tongue in the oral cavity. Both ends of the intermediate tube 2 are provided with curved side tubes 4 that extend backward. The side tubes 4 correspond to the horizontal inner walls of the oral cavity. The outer ends of the side tubes 4 are provided with extension tubes 5. The connection between the intermediate tube 2 and the side tubes 4 forms an occlusal position 11 corresponding to the position of the molars inside the oral cavity. The two extension tubes 5 are both inclined to extend outward, so that an eight-shaped structure is formed between the two extension tubes 5, wherein the end of one extension tube 5 is closed, and the end of the other extension tube 5 is open and provided with a pagoda joint 8.

[0023] The tongue depressor 3 or the middle tube 2 is provided with a plurality of lighting lamps 6, which are waterproof LED lamps, and the end-closed extension tube 5 is provided with a USB power supply interface 7 connected to the lighting lamps 6. The USB power supply interface 7 and the pagoda connector 8 are outside the coverage of the soft rubber layer 1.

[0024] A side lip embedded plate 9 is provided at the connection between the middle tube 2 and the extension tube 5. The lip embedded plate 9 is located on the outside of the pipe. The side lip embedded plate 9 corresponds to the corners of the mouth on both sides of the oral cavity. The middle part of the side lip embedded plate 9 is fixed to the pipe. The upper and lower ends of the side lip embedded plate 9 are bent inward, and the front and rear sides of the side lip embedded plate 9 are bent outward, so that the outer side of the side lip embedded plate 9 forms a groove 10 that matches the lips of the oral cavity.

[0025] The middle part of the middle tube 2 protrudes inward, so that the middle part of the middle tube 2 is away from the uvula of the oral cavity, thereby alleviating the patient's nausea.
