Referring to Figures 1 to 6, an oral medical auxiliary equipment includes an auxiliary chair 4. A head support 1 is provided on the auxiliary chair 4. The opposite sides of the head support 1 are rotationally connected to a limited slide 3. The limited slide 3 is slidably connected with a sliding rod 2. One end of the two sliding rods 2 adjacent to each other is fixedly connected with a positioning frame 20. The opposite ends of the positioning frame 20 are provided with limit rods 14. The limit rod 14 is slidably connected with a slider 15. The block 15 is provided with parallel threaded holes and through holes. A rotating rod 16 is provided in the threaded hole, and a limiting post 17 is provided in the through hole. The end of the rotating rod 16 is rotationally connected to the bite plate 18, and the limiting post 17 is connected to the bite plate 18. The bite plates 18 are fixedly connected, and the two opposite bite plates 18 are used to open the oral cavity.

Specifically, the limit slide 3 is a rectangular rod structure with a strip groove. The end of the slide rod 2 is damped and slidably connected in the strip groove. The slide rod 2 can move along the length direction of the strip groove. Move, the patient's head is placed at the head support 1 position, the positioning frame 20 can be placed above the patient's face by rotating the limiting slide 3, and then the sliding rod 2 is controlled to move the positioning frame 20 to a suitable position in the patient's mouth. , and slide the slider 15 to keep the bite plate 18 away from the injured position. At this time, the patient opens his mouth and bites the bite plate 18, and the medical staff rotates the rotating rod 16 to open the patient's mouth until the treatment needs are met. Through the setting of this structure, It allows the patient to always keep his mouth open in a relaxed state, avoiding the stiffness caused by the patient's long-term opening. It also ensures that the patient can avoid unconscious closing of the mouth during oral examination and treatment.

In other preferred embodiments, the positioning frame 20 has a rectangular structure, with two parallel limiting rods 14 provided at the upper and lower ends. The slider 15 cooperates with the two limiting rods 14 at the same end at the same time. The length direction of the threaded hole It is perpendicular to the length direction of the limiting rod 14 . By arranging the positioning frame 20 in a rectangular structure, installation space for the upper and lower expansion components and the left and right expansion components can be provided to correspond to the upper and lower teeth and the left and right lips of the human oral cavity.

In other preferred embodiments, the bite plate 18 is provided with a movable cavity 21 inside, an opening is provided on the working surface, the opening is connected with the movable cavity 21, and a connecting column 23 is provided in the opening, and the cross-sectional area of the connecting column 23 is less than The opening area and the two ends of the connecting column 23 are respectively provided with movable blocks and bite blocks. The movable blocks are movably arranged in the movable cavity 21 and are connected to the inner wall of the movable cavity 21 through a return spring. The depth of the movable cavity 21 is slightly larger than the thickness of the movable block. Under normal conditions, the movable block is at the middle position of the movable cavity 21. Since the cross-sectional area of the connecting column 23 is smaller than the opening area, the bite plate 18 can move within a small range. It will not affect the work of medical staff. Through the setting of this structure, when the patient opens his mouth for a long time and feels facial discomfort, he can make slight facial movements by moving his teeth to achieve a relaxing effect.

Specifically, the bite plate 18 is provided with a suction tube 24. The suction tube 24 is connected to an external suction device through an external tube 22 for sucking liquid in the oral cavity. The external tube 22 is fixedly connected to the bite plate 18 below. . The suction tube 24 is disposed at the lower bite plate 18. When in use, the suction tube 24 is placed in the oral cavity to absorb the saliva produced by opening the mouth for a long time and the cleaning fluid during the medical process, thereby reducing the patient's pain. Number of times you lie down.

In other preferred embodiments, the positioning frame 20 is also provided with a limiting block 13. The limiting block 13 has a built-in through hole, and a drawbar 12 is slidably connected in the through hole. The drawbar 12 is provided with a lock pin 11 at one end and a locking pin 11 at the other end. There is a flared plate 19, the sliding rod 2 is provided with evenly distributed pin holes, and the locking pin 11 matches the pin holes. Through the arrangement of this structure, the patient's lips on one side or both sides can be expanded according to the needs of medical staff, so as to facilitate the operation of medical staff.
