[0016] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0017] Example 1

[0018] like Figures 1 to 3 As shown, this embodiment provides an adjustable mouth opener for assisting imaging equipment in observing oral soft tissues. The mouth opener body 1 is approximately elliptical in structure, and specifically includes a lip support 11 and a buccal mucosa support 12. The lip support 11 includes two telescopic parts 111 that are arranged in parallel and adjustable in length, and a connecting rod part 112 hinged at both ends of the telescopic part 111, and the connecting rod part 112 is arranged slightly downwardly inclined relative to the upper side wall of the telescopic part 111; the buccal mucosa support 12 includes two C-shaped The two ends of the support frame 121 and the C-shaped support frame 121 are respectively hinged to the ends of the two connecting rods 112 on the corresponding sides; when in use, the length of the telescopic part 111 is adjusted according to the size of the patient's mouth, and then the angle between the connecting rod 112, the telescopic part 111 and the C-shaped support frame 121 is adjusted, so that the opening size of the mouth opener body 1 in the length and width directions is different to meet the requirements of different mouth shapes. At the same time, it can open the patient's oral lips and cheek tissues as much as possible, so that the oral gums, mucosa and oral lips and cheek soft tissues are separated.

[0019] Furthermore, in order to avoid the influence of the soft tissue of the tongue on the observation of the imaging device, a tongue fixing frame 13 is detachably installed inside the mouth opener body 1, and the tongue fixing frame 13 includes a fixing seat 131 detachably installed on the inner wall of the telescopic part 111, a boss 132 embedded in the fixing seat 131 and threadedly connected thereto, a pressure rod 133 hinged on the boss 132, and a tongue supporting plate 134 arranged at the end of the pressure rod 133; when in use, the pressure rod 133 is rotated 90° relative to the boss 132, so that the tongue supporting plate 134 is extended into the patient's oral cavity, and the patient's tongue rests on the supporting plate 134, so that the lower edge of the patient's tongue does not contact the gums and mucosal tissues of the mandibular teeth; at the same time, the protruding height of the boss 132 relative to the top surface of the fixing seat 131 can be adjusted to compensate for the inherent height of the fixing seat 131, so that the tongue fixing frame 13 is suitable for patients with different mouth shapes.

[0020] Furthermore, the telescopic portion 111 includes a connecting sleeve 1111a and two sliding rods 1112a symmetrically and movably sleeved in the connecting sleeve 1111a.
