[0002] Difficulty in opening the mouth is one of the common sequelae after radical radiotherapy for nasopharyngeal carcinoma. The main reason is that radiotherapy causes sclerosis of the temporomandibular joint and fibrosis of the masticatory muscles, which often occurs 6 months to 2 years after radiotherapy. It is manifested as a reduction in the distance between the incisors when opening the mouth, and even trismus in severe cases, which seriously affects the patient's quality of life. At present, there is still a lack of good treatment for difficulty in opening the mouth caused by radiotherapy. Once it occurs, it will be difficult to reverse, and prevention is the main approach. The traditional method is to ask the patient to practice mouth opening activities after radiotherapy, and gradually open the mouth as wide as possible through training to restore the oral opening function, or use tools such as chopsticks, corks, openers, empty medicine bottles, etc. to assist the patient in supporting the mouth for mouth opening training. However, during training, auxiliary tools such as chopsticks, corks, openers, empty medicine bottles, etc. are not flexible enough, inconvenient to store, and are not cleaned and disinfected in a standardized manner, which are not conducive to the long-term implementation of mouth opening training.

[0003] The existing portable mouth opening trainer has the following problems:

[0004] 1. The opening distance for mouth opening training usually needs to be 3cm-5cm. During mouth opening training, patients cannot pay attention to their actual opening degree in real time and cannot achieve the ideal training effect.
