The breast cancer screening is an important measure for finding breast cancer at an early stage, treating the breast cancer at an early stage, improving the survival rate of breast cancer patients, reducing the death rate and reducing the medical cost, and is necessary for screening breast diseases regularly. The existing hospitals usually adopt the modes of palpation imaging, breast molybdenum target X-ray imaging, ultrasonic imaging and the like to detect patients, when the breasts are detected, the patients can adopt a supine position or a prone position, the patient feels comfortable in the supine position, but due to the action of gravity, the breasts are sagged and the full appearance and the pathological change characteristics of the breasts cannot be accurately displayed; although the breast can naturally droop by adopting the prone position, if the breast is not shaped, the detection result is not high in precision. At present, the traditional examining table for the breast surgery has the technical problems of lack of a fixing device for the breast of a patient, poor comfort in the examination process and inconvenience in examination.
In addition, in recent years, the proportion of breast cancer patients receiving breast protection surgery treatment is gradually increasing, while breast protection surgery generally uses a breast bracket as a position fixing device, such a breast bracket can only fix the supine position of a patient, but cannot directly fix the breast of the patient, for patients with large partial breasts, especially middle-aged and old women patients with obesity, the breast skin is loose, the breast is large and droops obviously, the mobility of breast tissues in front of the chest is large, therefore, the relative position of the breast in front of the chest is not fixed every time the patient positions, and the breathing motion also affects the position of the breast, at this time, the position of the affected breast is not easy to be fixed, therefore, when the breast protection surgery is performed on the breast by using the current breast bracket, the breast bracket with large breast is easy to cause a positioning error, and the positioning accuracy of the breast on the affected side is reduced, the precision required for surgical treatment cannot be satisfied.
In order to solve various technical problems in the process of patient breast detection and operation, research and development personnel are urgently needed to develop an examining table adopting a prone posture, the breasts of a patient can be shaped and fixed, the breast detection precision of the patient is required to be ensured, and the comfort level of the patient is also required to be ensured.
