Minimally invasive breast lump excision (Mammotome) is a minimally invasive breast lump excision procedure using the Mammotome system, which is guided by ultrasound monitoring with a clear view. The entire puncture procedure is performed under ultrasound monitoring to improve accuracy. It is a minimally invasive biopsy and treatment technique that allows for the diagnosis and treatment of breast lump disease through this minimally invasive surgical approach. The surgical instrumentation consists of two main devices, the rotary cutter and the vacuum suction pump, with an ultrasound positioning system to repeatedly cut the suspicious lesions of the breast until the lump is completely removed. A specimen of the breast is also obtained for pathological examination. The operation time is 10-30 minutes, and in some cases, the procedure can be performed on an outpatient basis, providing a faster and better method for early detection and diagnosis of breast cancer. If the pathological examination suggests breast cancer, radical breast cancer surgery should be performed as soon as possible. Minimally invasive surgery for breast lumps is quick and has the characteristics of minimally invasive, small scars, aesthetic, and multiple lumps can be removed with a single small incision in the same side of the breast, which is well accepted by patients. The surgery is performed under local anesthesia and is safe because it does not involve the organs in the chest or abdominal cavity. It is suitable for the diagnosis and treatment of most breast lump diseases.
