Problems solved by technology

[0002] Oral gingiva, mucosal tissue, etc. in the human oral cavity vary in shape from person to person, and the difference in shape can lead to different prognosis results of various treatments such as periodontal surgery, implant aesthetics, and even restoration and orthodontics. Both the functional performance of the teeth and the aesthetic design of the anterior teeth are of great significance, but they have been neglected for a long time due to the lack of reliable research methods
[0003] The existing mouth gag is simple in structure, and cannot adjust the opening for different groups of people. When CT or cone beam CT is used to evaluate and measure oral soft tissues, due to the differences between the images of gums and mucosal tissues in certain parts, the images of lips, cheeks, and tongue and other soft tissues are in close contact with each other, resulting in overlapping images and making it difficult to identify

Embodiment 1

[0020] Example 1, such as figure 1 and 2 As shown, this embodiment provides a gag that is convenient for observing the oral cavity. The gag body has an approximately elliptical structure, which specifically includes a lip support 11 and a buccal mucosa support 12. The lip support 11 includes a vertically parallel and adjustable length. The two telescopic parts 111, and the connecting rod part 112 hinged at the two ends of the telescopic part 111, and the connecting rod part 112 is slightly inclined downward relative to the upper side wall of the telescopic part 111; 11 Two C-shaped support frames 121 on both sides, the two ends of the C-shaped support frame 121 are respectively hinged with the ends of the two connecting rod parts 112 on the corresponding side; when in use, adjust the position of the telescopic part 111 according to the size of the patient's mouth. Length, and then adjust the angle between the connecting rod part 112, the telescopic part 111 and the C-shaped s...

Embodiment 2

[0025] Example 2, such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the structure of the telescopic part 111 is different, which is the same as the structure, that is, the telescopic part 111 includes a connecting sleeve 1111b, and the movable sleeve is placed in the connecting sleeve 1111b and engages with each other The first sliding plate 1112b and the second sliding plate 1113b, one end of the first sliding plate 1112b protruding from the connecting sleeve 1111b is hinged with the end of the connecting rod portion 112 on the corresponding side, and one end of the second sliding plate 1113 protruding from the connecting sleeve 1111b It is hinged to the end of the link portion 112 on the corresponding side.

Abstract

The invention discloses a mouth prop facilitating oral cavity observation, and belongs to the field of medical instruments. According to the technical scheme, the mouth prop utilizes a length-adjustable telescopic part and an angle-adjustable connecting rod part, so that the length and the width of the mouth prop, namely the opening size, can be conveniently adjusted, the applicability is good, lip and cheek soft tissues can be effectively separated, the boundary of gingiva and mucous membrane tissues can be clearly displayed on a CT or cone beam CT image, the thickness of gingiva and mucous membrane tissues can be measured, information provided by preoperative images is increased, preoperative evaluation and treatment of doctors are facilitated, a tongue fixing frame is detachably mountedinside, tongue soft tissues can be effectively separated, and soft tissue mucous membranes in the oral cavity can be effectively observed. The telescopic part adopts two different structures, the opening size of the mouth prop can be conveniently adjusted, and the mouth prop is simple in structure and convenient and fast to use.
