Description

Technical Field

[0001] This utility model relates to the technical field of mouthpieces for radiotherapy of head and neck tumors, specifically a mouthpiece for radiotherapy of head and neck tumors. Background Technology

[0002] In radiotherapy for head and neck tumors, such as tongue cancer and hard palate cancer, the use of mouthpieces can maximize the protection of normal tissues. For example, if tongue cancer is not irradiated with the mouth open, the tongue surface is tightly attached to the hard palate above it, so the hard palate cannot be avoided during irradiation. However, the mouthpiece separates them, which can prevent the hard palate from being irradiated, thereby significantly reducing the patient's radiotherapy reaction.

[0003] The opening angle of existing head and neck tumor radiotherapy mouthpieces is difficult to fix, causing the upper and lower mouthpieces to merge during radiotherapy, which affects the treatment of head and neck tumors. The upper and lower mouthpieces use the same tongue plate, so only one side can be protected, and the other side has too much radiotherapy reaction. Summary of the Invention

[0004] The purpose of this invention is to provide a mouthpiece for radiotherapy of head and neck tumors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A head and neck tumor radiotherapy mouthpiece includes an upper mouth sleeve, a movable shaft, a lower mouth sleeve, and a fitting assembly. The lower mouth sleeve is mounted on a movable portion of the upper mouth sleeve, and a movable shaft is provided at the mounting portion of the lower mouth sleeve. The upper and lower mouth sleeves are assembled at an assembly portion of the fitting assembly, and the assembly also includes [further details needed]. Support components are installed on the lower opening sleeve; The tongue plate assembly is disposed on the upper mouth sleeve; The upper mouth sleeve is equipped with an upper tongue plate at the middle part, and an opening hole is opened inside the upper mouth sleeve. A movable hinge is provided at the movable part of the rear end of the upper mouth sleeve. A lower tongue plate is fixedly installed in the middle of the lower mouth sleeve, and a rubber support column is provided in the middle of the lower tongue plate.

[0006] The head and neck tumor radiotherapy mouthpiece described above: the upper mouthpiece and the lower mouthpiece are opened and closed by a hinge.

[0007] The head and neck tumor radiotherapy mouthpiece described above: the rubber support column and the lower tongue plate are supported and mounted on the upper mouthpiece sleeve and the upper tongue plate.

[0008] The head and neck tumor radiotherapy mouthpiece as described above: the support assembly includes a mounting base fixedly connected to the lower mouthpiece sleeve, and the mounting base has a threaded hole in the middle.

[0009] As described above, the head and neck tumor radiotherapy mouthpiece: the threaded hole and the mounting base are movably mounted with the rubber support column, which is supported inside the opening mouthpiece hole.

[0010] The head and neck tumor radiotherapy mouthpiece described above: the tongue plate assembly includes a support hole opened inside the upper tongue plate, and a front tongue plate is movably mounted on the front end of the upper tongue plate.

[0011] The head and neck tumor radiotherapy mouthpiece described above: the front tongue plate is mounted on the rubber support column and the lower tongue plate through a support hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the opening angle of the mouthpiece for radiotherapy of neck tumors can be fixed by the rubber support column inside the upper and lower mouthpieces, thus preventing the upper and lower mouthpieces from merging during radiotherapy. The lower tongue plate in the upper and lower mouthpieces is fixed by the opening of the rubber support column, which can position the lower tongue plate and facilitate radiotherapy treatment of head and neck tumors.

[0013] The lower and upper tongue plates can be used for oral support in the mouth during radiotherapy for head and neck tumors. In radiotherapy for head and neck tumors, the upper and lower mouth covers can be provided with lower and upper tongue plates for upper and lower mouth protection, reducing the patient's reaction to radiotherapy from both sides of the mouth.
