Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a radiotherapy body position fixing device. Background Art

[0002] Radiotherapy is a method of treating tumors by using the ionizing radiation of high-energy rays to kill cancer cells. X-rays, gamma rays and charged particles such as electrons, protons and heavy ions are common types of radiation used in cancer radiotherapy. Like surgery, it is one of the important local treatments for cancer patients. Raising both hands and holding the elbows on the forehead to fix it is the most common position fixation method for radiotherapy of chest tumors, and is suitable for radiotherapy of most chest tumors.

[0003] In the existing device, when patients undergo chest tumor radiotherapy, they need to put their hands backwards, so an armrest is set behind the patient's head. When the patient grabs the armrest backwards, the position of the armrest is usually fixed and cannot be adjusted. Because the body shapes of patients are different, some patients may not be able to reach the armrest when the patient puts his hands backwards to grab the armrest, which is not very convenient. In addition, patients who need to lie prone or lying down also need to add additional tools, which is troublesome. Therefore, the utility model provides a radiotherapy body position fixing device to solve the problems raised in the above background technology. Utility Model Content
