During the oral examination, the patient is usually required to open his mouth to facilitate the insertion of instruments and equipment into the patient's mouth for examination. In the actual operation process, the patient often closes his mouth unconsciously due to the patient's nervousness or the stimulation of the instrument, which causes many inconveniences for oral examination. Summary of the invention

[0003] The purpose of the present invention is to provide an oral cavity detection and expansion device to solve the above-mentioned problem. The oral cavity of a patient can be expanded and expanded according to actual operating conditions to facilitate detection.

[0004] To achieve the above object, the present invention provides the following solutions:

[0005] An oral detection expansion device comprises a connecting block, one side of the connecting block is universally connected with at least four expansion rods, the multiple expansion rods are divided into two groups, the multiple expansion rods in one group are connected to the same expansion component at one end away from the connecting block, the two groups of expansion rods are correspondingly connected with an opening component, the two groups of expansion rods are used to press against the teeth, and the two expansion components are used to expand the lips.

[0006] Preferably, the expansion assembly comprises an expansion support rod, one end of which is universally hinged to the side wall of the expansion support rod, and the other end of the corresponding expansion support rod is slidably connected in a sliding sleeve, and an expansion support component is provided inside the sliding sleeve.

[0007] Preferably, the expansion support component includes a first gear rotatably connected to the sliding sleeve, the first gear is coaxially arranged with the expansion support rod, the two ends of the first gear are respectively axially connected with threaded rods, the threaded rods are threadedly connected to the corresponding expansion support rods, the thread directions of the two threaded rods are opposite, the first gear is meshed with the expansion threaded rod, the expansion threaded rod is rotatably connected to the sliding sleeve and is perpendicular to the axis of the expansion support rod.

[0008] Preferably, the expansion component includes an expansion guide rail, which is of an arc-shaped structure. A first sliding groove is formed on one side of the expansion guide rail, and a second sliding groove is formed on the other side of the expansion guide rail. A plurality of sliding blocks are slidably connected in the second sliding groove, and the expansion rod is universally connected to the corresponding sliding block. At least two expansion sliding blocks are slidably connected to the outside of the expansion guide rail. An arc-shaped rack is fixedly connected to the side wall of the first sliding groove, and an expansion driving part is installed on the expansion sliding block, and the expansion driving part is in transmission connection with the arc-shaped rack.

[0009] Preferably, the expansion driving part includes a support sliding sleeve fixedly connected to the expansion sliding block. An expansion rod is slidably connected inside the support sliding sleeve. An adjusting gear is rotatably connected to the middle of the support sliding sleeve. The adjusting gear is threadedly connected to the outside of the expansion rod.

Then insert the expansion rods into the patient's mouth and make the teeth bite to the appropriate groove position according to the opening size of the patient's mouth. Then adjust the expansion screw rod again. Under the rotation of the expansion screw rod, the first gear rotates accordingly and drives the two screw rods to rotate. Since the two screw rods are provided with threads in different directions, the two expansion support rods will move away from each other, further pushing the expansion rods in different groups to move away from each other, realizing the preliminary opening of the patient's mouth. When further expansion of the patient's lips is required, by rotating the adjusting rod, the adjusting rod drives the adjusting gear to rotate. The adjusting gear is threadedly connected to the expansion rod, so that the expansion rod can expand outwards, and then drives the expansion hook to move outwards. The function of the expansion hook is to hook the patient's lips, so that the patient's lips do not block the teeth, providing more detection space for the detection device; the cooperation of the second chute and the slider can adjust the support position of the expansion rod for the patient's tooth part. When it is inconvenient to insert the detection device in some special cases, the support position of the expansion rod can be changed by adjusting the position of the slider, facilitating the further detection of the device. The expansion slider is arranged to slide along the expansion guide rail, which can change the adjustment of the expansion position of the patient's lips and avoid the problem that the detection device is inconvenient to extend into the oral cavity during the detection process.

[0026] A further optimized solution is that the expansion support component includes a first gear 401 rotatably connected to the sleeve 4, the first gear 401 is coaxially arranged with the expansion support rod 3, the two ends of the first gear 401 are respectively axially connected with threaded rods 402, the threaded rods 402 are threadedly connected to the corresponding expansion support rods 3, and the thread directions of the two threaded rods 402 are opposite, the first gear 401 is meshed with the expansion support threaded rod 5, the expansion support threaded rod 5 is rotatably connected to the sleeve 4 and is perpendicular to the axis of the expansion support rod 3.

[0027] For a further optimized solution, the expansion component includes an expansion guide rail 6, which has an arc-shaped structure. A first chute 601 is formed on one side of the expansion guide rail 6, and a second chute 603 is formed on the other side of the expansion guide rail 6. A plurality of sliders 13 are slidably connected in the second chute 603. The expansion rod 2 is universally connected to the corresponding slider 13. At least two expansion sliders 7 are slidably connected to the outside of the expansion guide rail 6. An arc-shaped rack 602 is fixedly connected to the side wall of the first chute 601. An expansion driving part is installed on the expansion slider 7, and the expansion driving part is in transmission connection with the arc-shaped rack 602.

[0028] For a further optimized solution, the expansion driving part includes a support sliding sleeve fixedly connected to the expansion slider 7. An expansion rod 8 is slidably connected inside the support sliding sleeve. A regulating gear 10 is rotatably connected to the middle of the support sliding sleeve.

The adjustment gear 10 is threadedly connected to the expansion rod 8, so that the expansion rod 8 can expand outwards, and then drives the expansion hook 12 to move outwards. The function of the expansion hook 12 is to hook the patient's lips, so that the patient's lips do not block the teeth, providing more detection space for the detection device; the cooperation of the second chute 603 and the slider 13 can adjust the support position of the expansion rod 2 for the patient's tooth part. When it is inconvenient to insert the detection device in some special cases, the support position of the expansion rod 2 can be changed by adjusting the position of the slider 13, facilitating the further detection of the device. The expansion slider 7 is arranged to slide along the expansion guide rail 6, which can change the adjustment of the expansion position of the patient's lips, and can avoid the problem that the detection device is inconvenient to extend into the oral cavity during the detection process.
