Description

Technical Field

[0001] The utility model relates to the technical field of image acquisition, in particular to an oral cavity image acquisition device. Background Art

[0002] Common oral diseases include oral ulcers, throat diseases, and dental diseases, which require doctors to view images of lesions in the oral cavity before they can perform subsequent treatment. For example, the patent with publication number CN211187158U discloses an intraoral image acquisition device, including an intraoral image acquisition device and a display device. The image acquisition device is used to acquire images of the patient's oral cavity, and the display device is used to display the images acquired by the image acquisition device. The image acquisition device also includes an image acquisition module, a camera mounting block, a microprocessor, and a transparent envelope. The image acquisition module is fixedly arranged at one end of the intraoral image acquisition device, and is used to acquire images of the patient's oral cavity and transmit them to the microprocessor. The microprocessor processes the received images and transmits them to the image transmission module for output, which is displayed on the display device.

[0003] Although the above-mentioned device can capture images inside the oral cavity, during the capture process, when the device is inserted into the oral cavity, the inner wall of the oral cavity will squeeze the device, resulting in poor image capture effect and a small capture range. The lens's line of sight is easily blocked by the inner wall of the oral cavity, and saliva in the mouth will also have a certain impact on the capture.

[0004] To this end, the utility model provides an oral image acquisition device. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 5 The utility model provides a technical solution: an oral image acquisition device, comprising a lens sleeve 2, a long lens 1 is installed in the lens sleeve 2, a flushing pipe 4 and a water suction pipe 5 are opened in the lens sleeve 2, a plurality of lighting structures are fixed on one side of the lens sleeve 2, a connecting tube 9 is slidably fitted on the lens sleeve 2, a handle 8 is fixed to one end of the connecting tube 9, a mounting plate 10 is fixed to the other end of the connecting tube 9, a plurality of support plates 13 are rotatably fitted on one side of the mounting plate 10, a fixing ring 12 is fixed on one side of the mounting plate 10, the fixing ring 12 is elastically connected to the support plate 13, and an adsorption structure is installed between the fixing ring 12 and the support plate 13.

[0024] In this embodiment, the lighting structure includes a plurality of lamp beads 6 fixed to one side of the lens cover 2 , and the lamp beads 6 are evenly distributed around the circumference of the lens cover 2 .

[0025] Specifically, when the device is inserted into the oral cavity, the oral cavity can be illuminated by the lamp beads 6, thereby facilitating the acquisition of oral images. Water can be flushed into the oral cavity through the flushing pipe 4 and water can be absorbed through the suction pipe 5 to prevent saliva from affecting the acquisition.

[0026] A sealing ring 3 is fixed to the periphery of the telephoto lens 1 , and the sealing ring 3 corresponds to the lens sleeve 2 .

[0027] Specifically, the gap between the telephoto lens 1 and the lens case 2 can be sealed by the sealing ring 3. The sealing ring 3 can also play a certain squeezing and fixing role. The telephoto lens 1 can be taken out of the lens case 2 by pulling the telephoto lens 1, which facilitates the disassembly of the telephoto lens 1.

[0028] A fixing rod 7 is fixed on the lens cover 2, and the handle 8 is slidably connected to the lens cover 2. A ball groove is opened in the mounting plate 10, and a ball head 11 is fixed to one end of the support plate 13, and the ball head 11 corresponds to the ball groove. A plurality of springs 14 are fixed between the fixing ring 12 and the support plate 13. The adsorption structure includes a plurality of electromagnets 16, and the electromagnets 16 are fixedly connected to the fixing ring 12. An adsorption sheet is fixed to the opposite inner side of the support plate 13. A waterproof cover 15 is fixed on the fixing ring 12, and the electromagnet 16 is located inside the waterproof cover 15.

[0029] Specifically, when capturing images, one can hold the fixing rod 7 and then push the handle 8 forward, so that the handle 8 drives the mounting plate 10 forward, thereby pushing the fixing ring 12 and the support plate 13, so that the area in front of the telephoto lens 1 is cleared, preventing the view in front of the telephoto lens 1 from being blocked.

[0030] When the space around the long lens 1 needs to be expanded, the electromagnet 16 is powered off so that the electromagnet 16 no longer adsorbs the fixed adsorption sheet. At this time, the spring 14 rebounds and the support plate 13 is opened, thereby expanding the space around the long lens 1 to ensure the image acquisition effect.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
