Proton and heavy ion treatment is an advanced treatment technology in the current radiotherapy field, and due to the physical characteristics of the Bragg peak of ions, most of energy can be deposited in the Bragg peak area, and the dose of the incident area, the lateral direction of the beam current and the tail end is lower, so that the irradiated dose of normal tissues around a target area can be reduced. The carbon ions also have higher biological effect and better curative effect on radiation-insensitive tumors. Uveal malignant melanoma is a rare malignancy of the eyeball, including choroidal, ciliary, and iris. European incidence is 5-7 cases per million people per year, asian incidence is 0.4-0.6 cases per million people per year. The main treatment means comprise eyeball excision, partial excision, thermotherapy, photon radiotherapy, particle brachytherapy and ion radiotherapy. Radiation therapy has become a major means of treatment for ocular tumors. Proton and heavy ion radiotherapy has been reported to provide superior therapeutic effects in tumor control, eye protection, vision, and incidence of adverse events. Involuntary movements of the eyes of a person may occur and the position of the eyes may change from moment to moment. In the tumor radiotherapy process of the eyeball, the rotation of the eyeball can cause the change of the tumor position, thereby possibly affecting the treatment precision and even causing treatment failure. Therefore, the radiotherapy of the tumor of the eyeball requires the fixation of the position of the eyeball, and the position of the eyeball is basically consistent with that of the eyeball when the CT scanning is planned, the error is within the acceptable range of clinical treatment, and the patient cannot keep the stability of the relative position in the treatment process, so that a stable head fixing device is required to fix the head part of the patient in the radiotherapy, thereby carrying out the radiotherapy on the affected part more accurately.
