Technical Field

The invention relates to the technical field of medical instruments, in particular to a mouth opening training device after tumor radiotherapy treatment.

Background

Tumor radiotherapy is a local treatment for tumors using radiation. The radiation includes alpha, beta and gamma rays generated by radioactive isotopes, and x-rays, electron beams, proton beams and other particle beams generated by various x-ray therapeutic machines or accelerators. About 70% of cancer patients require radiation therapy in the course of cancer treatment, and about 40% of cancers can be cured by radiation therapy. The role and position of radiotherapy in tumor treatment are increasingly prominent, and the radiotherapy has become one of the main means for treating malignant tumors.

After tumor radiotherapy is clinically carried out, the oral cavity is difficult to naturally open to the original state due to side effects, in order to enable a patient to well train the mouth, the mouth is usually trained by making a taper shape by hands or a wooden plug, but the operation is inconvenient, and the patient feels uncomfortable.
