This technology is the most advanced minimally invasive biopsy and treatment technology. Under the guidance of ultrasound or mammogram, it uses the principle of combining vacuum-assisted and rotary cutting to perform accurate and reliable sampling or minimally invasive excision treatment of breast lesions through a computer-controlled vacuum-assisted high-speed rotary cutting breast therapeutic device. It is capable of removing breast lesions that are clinically inaccessible or difficult to be removed by traditional surgery, which greatly improves the diagnostic accuracy of early breast cancer. Who are suitable for ultrasound-guided minimally invasive rotary mastectomy? 1.Lesions found by ultrasound that cannot be reached by conventional physical examination and have suspicious malignant signs; 2.Lumps found by ultrasound or physical examination during the follow-up process that are increasing rapidly; 3.Multiple lumps in the breast that require minimally invasive cosmetic treatment. The superiority of ultrasound-guided minimally invasive rotational excision of breast masses 1. minimally invasive, local anesthesia is sufficient, short operation time, the operation can be completed within half an hour; 2. ultrasound guidance, precise positioning, accurate and complete excision; 3. small skin incision (2-5mm), good cosmetic effect; 4. large amount of excised specimens, accurate pathological diagnosis.
