[0024] It should be noted that, holding the tongue fixing device for radiotherapy, the tongue depressors 22 on both sides are inserted along the direction of the patient's oral entrance. After insertion, the patient's upper and lower teeth respectively bite the occlusal grooves 11 of the support plate 10, and a movable wrench 21 on one side is moved to a determined position on the slide rail 12 of the support plate 10, and then the movable wrench 21 is fixed in the slot 13 of the support plate 10; similarly, another movable wrench 21 on the other side is moved to a determined position on the slide rail 12 of the support plate 10, and then the movable wrench 21 is fixed in the slot 13 of the support plate 10. At this time, the patient's tongue is fixed to the opposite side. In this embodiment, the tongue fixing device for radiotherapy can effectively protect the patient's normal tongue tissue from unnecessary radiation damage during radiotherapy, improve the overall efficacy of the treatment, and reduce the radiation dose received by the patient's normal tongue tissue.

[0025] In the embodiment of the present application, both the adjustable wrench 21 and the tongue depressor 22 are provided with a mounting hole 24 connected to the connecting shaft 23 .

[0026] It should be noted that the mounting hole 24 is provided for mounting the connecting shaft 23 .

[0027] In the embodiment of the present application, the tongue fixing device for radiotherapy can be made of food-grade plastic material, and can also be made of other materials according to needs.

[0028] The present application provides a tongue fixing device for radiotherapy, comprising a support plate and a tongue depressing mechanism movably arranged on the support plate, wherein the upper and lower end surfaces of the support plate are provided with bite grooves, and the tongue depressing mechanism comprises two tongue depressing assemblies located on the inner side of the support plate, and each tongue depressing assembly comprises an adjustable wrench and a tongue depressing piece, and the adjustable wrench is movably connected to the tongue depressing piece through a connecting shaft. The tongue fixing device for radiotherapy first places the tongue depressing piece on the patient's tongue and the patient's teeth are in contact with the bite groove, and the position of the tongue depressing piece is adjusted by moving the adjustable wrench on the support plate, and after the position is adjusted, the tongue depressing piece is fixed by the adjustable wrench, so that the tongue depressing piece fixes the patient's tongue, which is convenient for the patient's treatment, and solves the technical problem that there is no tongue fixing tool for the treatment of tongue cancer patients, and the treatment of patients is inconvenient.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, a slide rail 12 is provided at the lower end of the support plate 10 , and the tongue depressor 22 is movably connected to the slide rail 12 .

[0030] It should be noted that the slide rail 12 and the support plate 10 are integrated, and the slide rail 12 is designed to facilitate the movement of the tongue depressor assembly.

[0031] like Figure 1 and Figure 2As shown, in one embodiment of the present application, a plurality of slots 13 for fixing the tongue depressing mechanism 20 are provided on the upper end surface of the support plate 10 located above the slide rail 12 .

[0032] It should be noted that during the treatment of the patient, the upper and lower bite grooves 11 of the tongue fixing device for radiotherapy are engaged to naturally stretch the patient's mouth. Under the action of the movable wrench 21, the tongue depressor 22 can slide along the inner side of the support plate 10. After the tongue depressor 12 is slid to a fixed position, the movable wrench 22 is clamped and fixed in the clamping groove 13 of the support plate 10, thereby realizing the movement or displacement of the patient's tongue. Among them, the natural stretching and fixation of the patient's mouth is realized by the design of the upper and lower bite grooves 11 that match the patient's teeth. The densely arranged clamping grooves 13 on the top surface of the support plate 10 can meet the size of the tongue stretching and displacement in different scenarios, providing a more convenient access for treatment. The tongue depressor 22 slides along the slide rail 12 to achieve stable transmission of displacement, avoiding damage to soft tissue caused by unstable displacement.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, a connection hole 221 is formed at one end of the tongue depressor 22 to match and install with the slide rail 12 .

[0034] It should be noted that the connection hole 221 is used for movably connecting with the slide rail 12 .

[0035] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, an arc-shaped pressing piece 222 for fixing the tongue protrudes from the inner side of the tongue pressing piece 22 away from the support plate 10. An arc-shaped groove 223 is provided on the inner side of the tongue pressing piece 22 away from the support plate 10. The arcs of the arc-shaped pressing piece 222 and the arc-shaped groove 223 are the same.

[0036] It should be noted that the movable wrench 21 is connected to the tongue depressor 22, and the movable wrench 21 can rotate around the connecting shaft 23. A connecting hole 221 is provided next to the connecting shaft 23, and the connecting hole 221 can slide along the slide rail 12. An arc groove 223 is designed on the inner side of the tongue depressor 22, and the arc groove 223 can match the side of the patient's tongue. The arc groove 223 is integrally connected to the arc pressing piece 222, and the arc groove 223 has the same curvature as the arc pressing piece 222. In this embodiment, the tongue fixing device for radiotherapy can quickly capture the contour of the patient's tongue side through the arc pressing piece 222, thereby achieving flexible and convenient fixation or displacement. The curvature of the arc pressing piece 222 matches the contour of the side of the tongue, which is convenient for better fitting of soft tissue.
