TECHNICAL FIELD

[0001] The utility model belongs to compensating device technical field, especially relate to a individualized organization compensating device. BACKGROUND

[0002] Oral cancer is a relatively common malignant tumor of head and neck, and radiotherapy is one of the main treatment methods for oral cancer patients. In recent years, precise radiotherapy represented by intensity modulated radiotherapy technology has played an important role in improving the local control rate of oral tumors, but the incidence of radiation damage such as dental caries, oral mucositis, and xerostomia is still high, which seriously affects the quality of life of patients. As a preventive measure, mouthpiece has attracted attention from scholars at home and abroad.

[0003] Now the hospital in some patients with nasopharyngeal carcinoma, tongue cancer, tonsil cancer and other head and neck tumor radiotherapy, all require patients to open their mouths, use the tongue depressor to fix the tongue, to achieve fully expose the irradiated tissue in the oral cavity, also to achieve the normal tissue in the oral cavity is pushed away from the field, so that it is not irradiated, so as to improve the effect of radiotherapy, reduce the normal tissue dose, reduce the side effects of radiotherapy.

[0004] Due to the oral swallowing activity and tongue involuntary movement during radiotherapy, the target area may be displaced, which may lead to target deviation and off-target, ultimately leading to local tumor recurrence and treatment failure. To avoid the above situation, conventional mouthpiece is often used in clinic to reduce oral activity and tongue movement during treatment. However, the conventional mouthpiece is relatively short and cannot fix the active part of the whole tongue well, and the repeatability of fixation is poor.

[0005] Some existing mouthpieces for radiotherapy can keep the patient's mouth open and the tongue fixed during radiotherapy, but there are still some problems. For example, due to the special structure of the oral cavity and the tongue, the position of the mouthpiece changes greatly during fractionated radiotherapy, the shape of the mouthpiece changes easily, and the mouthpiece is difficult to fix, resulting in poor repeatability of using the mouthpiece, and it is difficult to ensure the repeatability of the patient's maxillofacial and tongue position during each radiotherapy, which may aggravate the radiation damage of the oral mucosa and the tongue. The tongue cannot be effectively fixed, which makes it difficult to maintain consistent body position during radiotherapy, and cannot achieve individualization, that is, each patient has his own separate mouthpiece.

[0006] Due to the increase of the oral cavity of the existing mouthpiece during use, the existence of the cavity will reduce the surface dose of the target area, and in the radiotherapy plan design, human equivalent tissue needs to be used for dose repair to correct the dose of the rays.
