Description

Technical Field

[0001] The utility model relates to the technical field of radiotherapy, in particular to an adjustable breast bracket. Background Art

[0002] Breast cancer is a systemic disease. The size of the surgical resection of early breast cancer has little effect on the patient's prognosis. The principle of modern tumor treatment is to focus on preserving and improving the patient's quality of life (function and appearance) while performing radical treatment. This is reflected in the treatment of breast cancer, where the scope of surgical resection tends to be smaller. The combined treatment of breast-conserving surgery and radiotherapy and chemotherapy for early breast cancer is the same as radical surgery or modified radical surgery in terms of local and regional control rates and long-term survival rates. Breast-conserving surgery and postoperative comprehensive treatment have become one of the main methods for treating early breast cancer.

[0003] Most patients who have undergone breast-conserving surgery for breast cancer need radiotherapy to reduce the recurrence rate. Since the breast target area is very close to the heart, lungs and healthy breast in anatomical position, the above normal tissues will inevitably be exposed to a certain dose of radiation during radiotherapy. In order to reduce the irradiation dose of normal tissues, it is urgent to develop auxiliary positioning devices to meet this demand. Currently, there are few products developed to meet this demand. Similar technical means are simply to lift the breast, and the freedom of movement of the support plate is limited, which affects the patient's comfort during treatment. In addition, there is no positioning of the specific lifting position, and the accuracy of each radiotherapy irradiation cannot be guaranteed. Utility Model Content
