Breast Mammotome Minimally Invasive Rotational Biopsy and Surgery The Mammotome Vacuum Assisted Minimally Invasive Rotational Biopsy System is the most advanced minimally invasive breast biopsy system in the world, which can repeatedly retrieve suspicious breast lesions to obtain breast histological specimens, providing a better method for early detection and diagnosis of breast cancer, as well as providing a technical basis for minimally invasive excision of benign tumors. 1.Precise location and accurate biopsy: Deep breast lesions and tiny tumors of about 5 mm in diameter can also be accurately biopsied. In the past, although such masses could be detected by ultrasound, they could not be reached and located by surgeons and could not be precisely removed by surgery. 2.Small incision and satisfactory appearance: Compared with the incision of 3-5 cm in traditional surgery, the incision of McMerton surgery is only 3-5 mm, no suture is needed and there is no obvious scar, and multiple tumors can be removed through the same incision, which has obvious advantages for deep tumors and breast enlargement. 3.Unique design, puncture safety: Unique hollow needle design, the whole operation is punctured only once, avoiding tissue damage and needle tract transfer of tumor cells caused by repeated punctures. 4.Large tissue volume, accurate pathology: biopsy of suspicious lesions can obtain large and continuous specimens, and the sample volume taken in one puncture is more than 5 times of general hollow needle, obtaining the same pathological diagnosis as open surgical biopsy, avoiding leakage and misdiagnosis. 5. Rapid surgery and low infection rate: McMurdo can save more than half of the surgery time compared with open surgery. The intra-operative residual wireless head avoids foreign body reaction, and the incision is small, so the infection rate is extremely low. Fibroadenoma of the breast Fibroadenoma of the breast is the most common benign tumor among breast diseases, which can occur at any age after puberty, mostly between the ages of 18-25. Its occurrence is related to estrogen stimulation. It is usually solitary, but in a few cases it is multiple and can occur unilaterally or bilaterally, and rarely becomes malignant. They are usually round or ovoid, and in large cases may be lobulated. The main clinical manifestation is a breast lump with a smooth surface, firm texture, clear borders, good mobility, and generally not associated with pain. The main methods of examination are physical examination, ultrasound and mammography. Once a fibroadenoma is formed, medication is ineffective and the only way is to remove it surgically. However, not all fibroadenomas must be removed, and those with small masses that are not considered malignant and are growing slowly can be observed and followed up. Surgical methods: ① Traditional open surgery: for clinically palpable fibroadenomas and tumors that are considered malignant, the incision is usually 3-5 cm and the scar is obvious. The advantages are low cost, low surgical difficulty, no need for auxiliary equipment, and all hospitals at all levels can complete the surgery. ②McMurdo minimally invasive rotational surgery: It is suitable for fibroadenomas under 2 or 5 cm, as well as small fibroadenomas that are larger in size and not clinically accessible. McMerton minimally invasive surgery has a quick recovery after surgery, with incisions of 3-5 mm, no sutures required and less likely to form scars.
