Description
Technical Field
[0001] The utility model relates to the technical field of oral photography, in particular to a precise positioning device for oral photography. Background Art
[0002] Oral photography is a commonly used method in oral medicine. Clinically, it is necessary to accurately record and compare the changes in dental hard tissues and periradicular tissues at different times, such as the progression of periodontitis, apical periodontitis, and alveolar bone resorption around implants.
[0003] Therefore, oral radiography requires that dental films taken at different times be comparable and reproducible, with the film's position within the mouth, the tube's position, and the projection angle being completely consistent for each exposure. Currently, most small and medium-sized hospitals use traditional manual procedures for dental radiography. This involves medical staff manually inserting the film, CCD probe, or CR imaging plate into the patient's mouth, and the patient then presses the film down to capture the image. This method, however, struggles to ensure consistent positioning and angles across multiple exposures, presenting certain limitations.
[0004] For this purpose, a precise positioning device for oral photography is proposed. Utility Model Content

[0024] like Figures 1 to 3As shown, a precise positioning device for oral photography comprises a table top 1, the bottom surface of which is fixedly connected to a support frame 6, the top surface of which is provided with a head positioning assembly 2, a pushing assembly 3 mounted in the middle of the top surface of the table top 1, a shooting assembly 4 mounted at the end of the pushing assembly 3, and an angle adjustment assembly 5 for controlling the rotation of the shooting assembly 4. More specifically, a patient sits on the left side of the table top 1, and their head is positioned by the head positioning assembly 2, thereby ensuring that the patient's oral cavity can be in the same position during multiple shots. The shooting assembly 4 is pushed into the oral cavity by the pushing assembly 3, and the pushing assembly 3 can control the pushing depth. The shooting assembly 4 can clamp the film for shooting, and the angle adjustment assembly 5 can control the shooting angle of the shooting assembly 4 to ensure that multiple shots are at the same angle. In use, the effect of facilitating precise shooting of the patient's oral cavity is achieved, and the angle and position of the shots taken at different times can be the same, thereby facilitating medical staff to understand the development of oral disease.
[0025] The head positioning assembly 2 includes a chin pad 201, which is fixedly connected to the left side of the top surface of the table top 1. A transparent baffle 202 is fixedly connected to the right side of the chin pad 201, and an entrance and exit 203 is formed through the surface of the transparent baffle 202. A mounting plate 204 is fixedly connected to the right side of the top surface of the table top 1, and a strip light 205 is fixedly mounted on the surface of the mounting plate 204. It should be noted that the patient's chin is placed on the surface of the chin pad 201, and the tip of the nose touches the surface of the transparent baffle 202. The vertical linear light emitted by the strip light 205 is used to align the patient's brow center, nose tip, and philtrum with the straight line, thereby determining the patient's oral position, allowing the patient to maintain a consistent posture during multiple photographs. The entrance and exit 203 facilitates the entry of the photographing assembly 4 for photographing. In actual implementation, the patient can be provided with a liftable chair to make the photographing process more comfortable.
[0026] The push assembly 3 includes a slide rail 301, which is fixedly connected to the top surface of the table top 1. A mounting rod 302 is slidably connected to the inner wall of the slide rail 301. The top surface of the slide rail 301 is provided with a first scale mark 303. The front and back surfaces of the mounting rod 302 are fixedly connected to a handle 304. More specifically, by grasping the handle 304, the mounting rod 302 can be pushed to slide along the inner wall of the slide rail 301, thereby driving the camera assembly 4 to move, allowing the camera assembly 4 to be inserted into the oral cavity for photography. By observing the first scale mark 303, the depth of the camera assembly entering the oral cavity can be determined.
[0027] The photographing assembly 4 includes a rotating shaft 401, which is rotatably connected to the end of the mounting rod 302. The left end of the rotating shaft 401 is fixedly connected to a fixing plate 402, the top of the fixing plate 402 is fixedly connected to a top plate 403, a photographing device 404 is fixedly mounted on the surface of the top plate 403, and a card slot 405 is fixedly connected to the bottom end of the fixing plate 402. It should be noted that the mounting rod 302 pushes the rotating shaft 401 and the fixing plate 402 into the oral cavity, and the film can be inserted into the card slot 405 for fixation. The film is then used in conjunction with the photographing device 404 to take dental film photos. The rotating shaft 401 is controlled to rotate by the angle adjustment assembly 5, which can drive the fixing plate 402, the top plate 403, the photographing device 404, and the card slot 405 to rotate, thereby adjusting the shooting angle.
[0028] The angle adjustment assembly 5 includes a mounting housing 501, which is fixedly connected to the surface of the mounting rod 302. A worm 502 is rotatably connected to the inner wall of the mounting housing 501, and a knob 503 is fixedly connected to the front end of the worm 502. A worm gear 504 is fixedly sleeved on the surface of the rotating shaft 401, and the worm gear 504 meshes with the worm 502. More specifically, by rotating the knob 503, the worm 502 rotates, thereby rotating the meshed worm gear 504, thereby controlling the rotation of the rotating shaft 401, thereby adjusting and controlling the shooting angle of the shooting assembly 4. The worm 502 and worm gear 504 are self-locking, preventing the rotating shaft 401 from accidentally rotating during shooting.
[0029] A pointer 505 is fixedly connected to the surface of the rotating shaft 401, and a second scale line 506 is set on the right side of the mounting shell 501. It should be noted that when the rotating shaft 401 rotates, it will drive the pointer 505 to rotate. By observing the second scale line 506, the rotation angle of the rotating shaft 401 can be accurately controlled.
[0030] In summary: the patient sits on the left side of the table 1, and his head is positioned by the head positioning component 2, so as to ensure that the patient's mouth can be in the same position in multiple shots, and the shooting component 4 is pushed into the mouth by the pushing component 3, and the pushing component 3 can control the pushing depth. The film can be clamped by the shooting component 4 for shooting, and the shooting angle of the shooting component 4 can be controlled by the angle adjustment component 5 to ensure that multiple shots are at the same angle. In use, it is achieved that the effect of facilitating accurate shooting of the inside of the patient's mouth is achieved, and the angle and position of shooting at different times can be guaranteed to be the same, so that it is convenient for medical staff to grasp the development of oral disease.
