[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. About 70% of cancer patients need radiotherapy during the treatment of cancer. The role and status of radiotherapy in tumor treatment are becoming increasingly prominent and has become one of the main means of treating malignant tumors.
[0003] Clinically, lung and upper abdominal tumors are common tumors. Due to the movement of the lungs, the organs in this area move a lot, usually 2-2.5cm. It is necessary to add an additional 2cm irradiation width to the range of the patient's liver activity to ensure that the patient's liver diseased part can always be irradiated during the radiotherapy process; however, the increase in the irradiation range also increases the irradiated area of the intact liver. The healthy liver part is easily affected by radioactive light, causing secondary damage to the patient. Common solutions include respiratory tracking, abdominal compression and 4D CT, etc., and their systems or devices have high equipment requirements, which are not conducive to use in primary hospitals.
[0004] Therefore, there is an urgent need for a simple abdominal compression device for tumor radiotherapy that can reduce respiratory motion to solve the above-mentioned problems. Summary of the invention
[0005] The purpose of the present invention is to provide a simple abdominal compression device for tumor radiotherapy that can reduce respiratory movement. The device has a simple structure and is easy to use. It can effectively prevent patients from performing abdominal respiratory movements and reduce the range of movement of the patient's internal organs.
