Vertically-separated support for oral cavity radiotherapy and manufacturing method thereof

Abstract

The invention discloses a vertically-separated support for oral cavity radiotherapy and a manufacturing method of the vertically-separated support. The vertically-separated support for oral cavity radiotherapy comprises a support body. The support body is a hollow shell. The external shape of the support body is matched with the intra-cavity shape, formed when a patient opens the mouth, of the oral cavity. The front portion of the support body is a fixed portion, and an upper surface shell and a lower surface shell of the fixed portion are provided with an upper dentition impression groove and a lower dentition impression groove respectively. The rear portion of the support body is a supporting tongue pressing portion, the upper surface of the supporting tongue pressing portion serves as a support palate surface, and the lower surface of the supporting tongue pressing portion serves as a support tongue surface. The fixed portion and the supporting tongue pressing portion are communicated through a ventilation channel. The oral cavity support is suitable for oral cavity jaw surface tumor radiotherapy, the exposure dose which endangers organs can be stably and effectively reduced, oral mucosa damage and taste damage generated in the oral cavity jaw surface tumor radiotherapy process are reduced, and compliance and quality of life are improved when the patient receives radiotherapy.

Description

technical field [0001] The invention belongs to the technical field of radiation therapy for head and neck tumors, and in particular relates to an upper and lower partition type oral bracket used in the radiotherapy process of oral and maxillofacial tumors and a manufacturing method thereof. Background technique [0002] Radiation therapy or radiotherapy-based comprehensive therapy is the basic principle for the treatment of head and neck tumors in today's medical field. More than 70% of head and neck malignant tumors require the intervention of radiotherapy in the course of their treatment. However, for a long time, parotid gland function damage, oral mucosa damage and taste damage caused by radiotherapy, resulting in dry mouth and oral diseases, have always been the most common complications in radiotherapy for head and neck malignant tumors, and these complications are serious. It affects the quality of life of patients, and sometimes even leads to the suspension of radio...

Problems solved by technology

At present, in order to reduce the radiation dose of the tongue and oral mucosa during radiotherapy, corks and disposable syringes are often used in China to push the tongue and part of the oral mucosa away from the target area. Disadvantages of poor position repeatability and inability to individualize
