Problems solved by technology

A variety of existing mouthpieces have different structures and no uniform standards, which cannot meet the needs of precise radiotherapy, specifically in the following aspects:
[0005] (1) The effect is inaccurate: the shape of the mouthpiece is different from the shape of the oral cavity, and the position of the oral cavity and tongue cannot be accurately fixed;
[0006] (2) Poor accuracy: the material is hard and cannot be adjusted according to the shape and position of the mouth and tongue;
[0007] (3) Poor individualization: the shape is single and cannot be adjusted according to the differences between individual patients;
[0008] (4) Poor repeatability: There is no registration standard for the placement of the mouthpiece between fractionated radiotherapy, which is random and random;
[0009] (5) The effect on radiation is uncertain: the selection of materials is not uniform, and the scattering effect of the mouthpiece on radiation cannot be accurately measured;
[0010] (6) Poor compliance: solid structure, patients can only breathe through the nasal cavity during radiotherapy, poor compliance
[0011] To sum up, in the prior art, there is still no effective solution to the problem of making mouthpieces that meet the requirements of precise radiotherapy for patients with head and neck tumors and are highly versatile.

Abstract

The invention discloses a method for making a mouthpiece suitable for radiotherapy of head and neck tumors and a mouthpiece, which solves the problem that the mouthpiece in the prior art has no unified standard and cannot meet the needs of precise radiotherapy. The structure is very consistent with the internal structure of the patient's oral cavity, which improves the accuracy of fixing the oral cavity and the tongue in the radiotherapy of head and neck tumors, which is beneficial to further reduce the radiation dose of the oral mucosa and the tongue, and improve the efficacy of radiotherapy. The technical scheme includes the following steps: Check the patient's mouth; cut out a rod with the same length as the patient's mouth to make it a model of oral support tongue depressor; locate and scan with large-aperture CT; 3D reconstruction of the mouthpiece model on the computer; print the mouthpiece model with a 3D printer.

Description

technical field [0001] The invention relates to the medical related technical field, in particular to a method for manufacturing a mouthpiece suitable for radiotherapy of head and neck tumors and the mouthpiece. Background technique [0002] Radiation therapy is the main technique for treating head and neck tumors. The incidence of radiation damage to the oral mucosa and tongue is close to 100%, and it is also one of the most serious side effects that have the greatest impact on the quality of life of patients, and it reduces their tolerance to treatment, and in severe cases, it will lead to delay or even interruption of treatment. thereby affecting the therapeutic effect. [0003] Due to the particularity of the anatomical structure of the oral cavity and tongue, the position and shape change greatly during fractionated radiotherapy, the fixation is difficult, the repeatability is poor, and there are great differences among individual patients. This feature not only aggra...
