[0039] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0040] An embodiment of the present application provides a support device.

[0041] Embodiment 1, as Figure 1-6 shown.

[0042] A mouth-opening device includes a lower mirror tube 1, which is a hollow cylindrical structure, and an endoscope extends into the patient's oral cavity from the inner cavity of the lower mirror tube 1. A lip baffle 11 is installed on the front side of the lower mirror tube 1, and the lip baffle 11 is an arc-shaped structure to adapt to the shape of the patient's lips.

[0043] A mouth support device, comprising a tooth support assembly 2, wherein the tooth support assembly 2 is mounted on the upper and lower sides of the lower mirror tube 1;

[0044] The tooth support assembly 2 includes an upper support assembly 21 and a lower support assembly 22. The upper support assembly 21 and the lower support assembly 22 have the same structure and are respectively mounted on the upper and lower sides of the lower mirror tube 1. They are respectively in contact with the upper and lower teeth of the patient to provide occlusal fixation.

[0045] The upper support assembly 21 includes an arc rod 211, a movable plate 212, and a tooth support member 213. The arc rod 211 is arranged above the lower mirror tube 1. The arc rod 211 includes a main rod 2111 and a side rod 2112. The main rod 2111 is a hollow structure. The side rods 2112 are slidably connected to the left and right sides of the inner cavity of the main rod 2111. Blocking plates 2113 are provided at the outer ends of the two side rods 2112. By pulling the side rods 2112, the overall length of the arc rod 211 can be adjusted to adjust the position of the movable plate 212. The curvature of the arc rod 211 is adapted to the curvature of the gums. The top surface of the arc rod 211 is slidably connected to a plurality of movable plates 212. The movable plates 212 slide left and right along the arc rod 211. The top surface of the movable plate 212 is slidably connected to the tooth support member 213, and the tooth support member 213 slides forward and backward along the movable plate 212. Some elderly patients have incomplete teeth in their mouths, so the tooth support 213 can be moved to the only remaining teeth for occlusion and fixation. The tooth support 213 can be moved left and right, front and back according to the actual situation of the patient to provide support for different patients and open the mouth to facilitate the subsequent endoscopic examination.

[0046] Furthermore, the tooth support 213 includes a support bottom plate 2131, a support side plate 2132, and a limiting protrusion 2133. The support side plates 2132 are respectively installed on the front and rear sides of the top of the support bottom plate 2131. The two support side plates 2132 are in an inverted eight-shaped shape, which increases the distance between the tops of the two support side plates 2132 so that the teeth can enter between the two support side plates 2132 more smoothly. The support side plates 2132 are in an inverted trapezoidal structure, which increases the length of the tops of the support side plates 2132, and can also make the patient's teeth enter between the two support side plates 2132 more smoothly when biting. The limiting protrusion 2133 is installed on the inner side of the support side plate 2132. The limiting protrusion 2133 is a silicone structure and is triangular. The patient's teeth are squeezed, fixed and supported by the two limiting protrusions 2133. At the same time, the limiting protrusion 2133 is a flexible structure, which can adapt to various types of patient teeth and provide oral support for them.

[0047] An extrusion belt 2134 is provided between the two limiting protrusions 2133. The two ends of the extrusion belt 2134 are connected to the middle tip surfaces of the two limiting protrusions 2133. By providing the extrusion belt 2134, the patient has a certain longitudinal space buffering bite stroke. The patient's facial masseter muscles have the ability to open and close at a certain angle, which relieves the pain in the patient's masseter muscles and improves the patient's comfort during use. That is, when the patient's masseter muscles are uncomfortable due to long-term mouth stretching, the patient can achieve oral occlusal activities within a certain angle by clenching and loosening the teeth, thereby relieving the discomfort of the masseter muscles.

[0048] A stabilizing plate 3 is disposed between the upper support assembly 21 and the lower support assembly 22 to increase the stability of the upper support assembly 21 and the lower support assembly 22 and avoid damage when the patient bites.

[0049] A mouth-opening device comprises a tongue-pressing assembly 4, which is installed on the rear side of the lower endoscope tube 1 to limit the tongue of the patient to avoid affecting the movement of the endoscope.

[0050] Furthermore, the tongue depressor assembly 4 includes a tongue cover 41, and the tongue cover 41 is installed at the rear end of the lower endoscope tube 1. The tongue cover 41 is a hollow triangular structure, and a notch is provided at the bottom of the tongue cover 41. When in use, the patient's tongue is inserted into the tongue cover 41, and the frenulum of the tongue passes through the notch, which will not cause discomfort to the patient. Compared with the tongue depressor, the design of the tongue cover 41 can completely restrict the patient's tongue, avoiding discomfort of the patient during the endoscopic examination, causing the tongue to twist, and affecting the movement of the endoscope tube.

[0051] A tongue depressor moving assembly 5 is installed between the tongue depressor assembly 4 and the lower mirror tube 1 to adjust the front and back position of the tongue cover 41 to adapt to various patients.

[0052] Furthermore, the tongue depressing moving assembly 5 comprises a moving rod 51, a handle 52, and a limiting rod 53. The moving rod 51 is slidably connected to the lower mirror tube 1. The handle 52 is installed at the front end of the moving rod 51. The rear end of the moving rod 51 is connected to the tongue depressing assembly 4. The lower mirror tubes 1 on both sides of the moving rod 51 are slidably connected to the limiting rods 53 along their length direction. The rear end of the limiting rods 53 is fixedly connected to the tongue depressing assembly 4. When in use, the handle 52 is pulled to move the tongue cover 41 forward and backward through the moving rod 51. The design of the limiting rods 53 on both sides can limit the tongue cover 41 to prevent the tongue cover 41 from rotating when moving.

[0053] A mouth-supporting device includes a suction component 6 installed outside the tooth support component 2 and the tongue depressor component 4. The device absorbs saliva in the oral cavity to prevent the saliva from flowing into the digestive tract and affecting the endoscopic examination.

[0054] Furthermore, the back-suction component 6 includes a connecting belt 61, a back-suction tube 62, and an outlet tube 63. The connecting belt 61 is arranged at the bottom of the lower support component 22. The two ends of the connecting belt 61 are fixedly connected to the two ends of the back-suction tube 62. The back-suction tube 62 is provided with a plurality of through holes. The middle part of the back-suction tube 62 is connected to the outlet tube 63. The other end of the outlet tube 63 passes through the lower mirror tube 1 and extends to the front end of the lower mirror tube 1. The outer end of the outlet tube 63 is connected to negative pressure, and the saliva is sucked out through the back-suction tube 62. The lower support component 22 is located on the surface of the patient's mandibular teeth, and the design of the connecting link allows the back-suction tube 62 to be located just on the inner side of the mandibular teeth. Saliva and the like flow on the inner side of the mandibular teeth and are sucked away and exported by the back-suction tube 62.

[0055] Furthermore, the back-suction component 6 also includes a water-absorbing cotton sheet 64 and an interception tube 65. The upper and lower sides and the side edges of the tongue cover 41 are covered with water-absorbing cotton sheets 64. A number of interception tubes 65 are evenly spaced on the water-absorbing cotton sheets 64 on the upper and lower sides. A number of through holes are provided on the interception tubes 65. The interception tubes 65 are connected to the back-suction tubes 62 through a pipeline. During the endoscopic examination, there are two main places where saliva accumulates, one is the inner side of the mandibular teeth, and the other is the surface and bottom of the tongue. The saliva produced near the tongue is adsorbed by the water-absorbing cotton sheet 64, and then sucked away and discharged through the interception tube 65.

[0056] When the present invention is used:

[0057] The patient opens his mouth and places the lower mirror tube into the mouth. At this time, the positions of the tongue cover and the tooth support are adjusted according to the actual situation of the patient.

[0058] After the adjustment is completed, the tongue is inserted into the tongue sleeve, and then the patient bites the teeth to fix the teeth in the tooth support. At this point, the mouth brace is completed. Subsequent treatment or endoscopic examination can be started.

[0059] During the examination, the saliva in the mouth is sucked out in time through the suction component.
