The traditional treatment of breast disease is surgical excision of the lesion, which is more traumatic and prone to scarring. As the standard of living and the awareness of patients have increased, the demand for medical technology has also increased, and more minimally invasive and precise techniques have become a trend. Minimally invasive rotational mastectomy has emerged. This technique is based on the principle of combining vacuum suction and rotary incision under the stereoscopic positioning of ultrasound or molybdenum target, based on more accurate biopsy, sufficient amount of tissue (10-15 strips 3mm thick x 20mm long, 1 strip is eight times thicker than ordinary needle), and more minimally invasive characteristics, and the diagnosis and treatment of breast diseases that cannot be performed by other methods. It is mainly composed of three major devices: the handle of the rotary cutter, the control host, and the vacuum pump. A small incision of 1 to 3 mm is made in the skin of the affected breast, a probe is punctured to the site of the breast lump, and the lump is completely removed through negative-pressure suction spinotomy. Minimally invasive rotational breast surgery can be performed on an outpatient basis with only local anesthesia and a short operative time to go home after surgery. There is minimal bleeding during surgery, only a small incision, no scarring after surgery, and minimal patient trauma. Indications for mastectomy biopsy surgery include: 1. Microscopic breast tumors that cannot be touched clinically and found by B-ultrasound: biopsy tumor tissue can be obtained through the guidance of B-ultrasound. Suspected breast lesions (e.g. calcified spots, nodular hyperplasia): other biopsy methods cannot obtain sufficient amount of tissue for pathological diagnosis. This system can obtain a sufficient amount of biopsy tumor tissue through image guidance. 3.Benign tumor: Mammography or B-ultrasound examination for benign breast masses. This system can completely remove benign masses below 3cm through B ultrasound guidance with only a 2-3mm incision to achieve minimally invasive treatment.
