However, radiotherapy stents made of traditional materials such as red and white proofing paste and polymer materials (such as polylactic acid) are large in size, which not only cannot locate the local lesion, but also easily causes radiation-induced oral mucositis in normal tissues.

The invention relates to the field of oral stents for radiotherapy, in particular to an oral radiotherapy stent. A mouth opening device part on the oral radiotherapy stent can effectively reduce sideeffects caused by radiotherapy, a tongue depressor can limit the movement range of the tongue, and it is ensured that the oral radiotherapy is carried out smoothly. A compensation material part connected with the mouth opening device can overcome the defect that the cavity and surface radiation dose is difficult to increased by utilizing the physical characteristic that the material generates manyscattered rays; through the use of the conformal compensation material at the local lesion in the oral cavity of a patient, the dosage on the local contact surface of the lesion can be effectively increased, and therefore the requirements in the dosimetry aspect of radiotherapy treatment are better met. Thus, the personalized oral radiotherapy stent can serve as an oral fixation and dose compensation device to be applied to radiotherapy of the oral and maxillofacial part and has great application prospects in the field of medicine. The method is simple, easy to implement and low in cost and has high practical value.
Description
technical field [0001] The invention relates to the field of oral cavity brackets for radiotherapy, in particular to an oral cavity radiotherapy bracket. Background technique [0002] Oral maxillofacial-head and neck cancer patients often need an auxiliary device that can not only increase the dose of the local contact surface of the lesion, but also reduce the impact on normal tissues when undergoing radiation therapy. However, radiotherapy stents made of traditional materials such as red and white proofing paste and polymer materials (such as polylactic acid) are large in size, which not only cannot locate the local lesion, but also easily causes radiation-induced oral mucositis in normal tissues. Therefore, we urgently need to design a cheap and easy-to-manufacture oral radiotherapy bracket to increase the dose of the local contact surface of the lesion and effectively reduce the side effects of radiotherapy. Contents of the invention [0003] The technical problem sol...
