(McMurdo) Minimally Invasive Rotary Incision Breast System is a breast biopsy puncture system manufactured by Johnson & Johnson Medical Devices, Inc. It is the most advanced minimally invasive biopsy system available, which consists of two main devices: the rotary cutter and the vacuum suction pump. The system pushes the traditional open surgery for breast masses to minimally invasive, and allows repeated cutting of suspicious breast lesions to obtain histological specimens of the breast, providing more and better methods for breast cancer detection and diagnosis, as well as providing a technical basis for minimally invasive excisional resection of benign tumors. Its characteristics are: minimally invasive and accurate. 1. Precise localization and accurate excision of lesions. Deep lesions and tiny tumors with a diameter of only 3 mm can be accurately excised. In the past, although such masses could be detected by ultrasound, the clinician could not reach and locate them by palpation and could only observe them and wait for them to grow up before performing surgery or extensive excision. 2.Small incision and good cosmetic effect. Compared with the incision of 3-5 cm in traditional surgery, the incision of McMurdo is only 3 mm, no suture is needed and no scar is left; and when there are multiple lesions in the same side of the breast, traditional surgery often requires multiple incisions, but McMurdo only needs to be removed through one incision (less than 3, distance not more than 10 cm). It avoids cutting through the skin, subcutaneous tissue and normal glands, resulting in less tissue damage and faster recovery, which is especially advantageous for patients with deep breast masses and obesity. 3. High-tech design ensures safety. Unique hollow puncture needle design, the whole procedure is punctured only once, avoiding needle tract metastasis caused by repeated multiple punctures of tumor cell shedding. 4. More accurate diagnosis. The biopsy of suspicious lesions can obtain large and continuous specimens, and the sample volume taken in one puncture is 8 times of the traditional hollow thick needle, which reduces the false negative rate of pathology by 50% (malignant tumor cells are not detected and misdiagnosed as negative due to small and limited specimen volume), and the biopsy site can be placed with marker clips to observe whether the lesion has malignant changes at any time. 5. Low infection rate. The application of electrocoagulation for hemostasis of conventional surgical incision can easily cause fat liquefaction, and the surgical sutures are retained in the incision as foreign bodies, which can easily cause incision infection and poor healing; McMurdo surgery does not have any foreign bodies remaining in human body, which significantly reduces the risk of infection and saves the cost of anti-infection. Mamotomme surgery is quick and convenient. Mamotomme surgery is short, light in pain, and can be performed in an outpatient clinic. 10-30 minutes for a single mass, and you can move freely after surgery, while traditional surgery is usually performed in the operating room, and patients often need bed rest and dietary guidance in many aspects to reduce symptoms after general anesthesia. Breast cancer has a malignant and progressive process. Early detection, early diagnosis, early treatment and standardized comprehensive treatment are the keys to improve the outcome. When a lump is found in your breast or a subclinical microscopic nodular lesion is detected by ultrasound, surgery is the best option to remove the lesion. The removal of lesions can prevent cancer and improve the cure rate and survival rate by biopsy for clear diagnosis to exclude cancer or early detection and treatment of cancer. The destruction of the perfect shape of the breast is unacceptable to the majority of women who love beauty. Traditional surgery to remove the tissue of the lesion has certain limitations and is more traumatic, especially in terms of postoperative scars. In theory alone, the McMerton technique is a way to remove the tumor through a large incision of about 3 mm, and under the guidance of B-ultrasound, the breast fibroids, which are several centimeters in size, are cut open and removed in stages. This procedure is less invasive and has a faster recovery, which is what McMerton advertises as “beautiful and scarless”. Although it is aesthetically pleasing and convenient, it is relatively expensive, costing close to $7,000 for the entire treatment and diagnosis process. In addition, McMerton surgery is only a small incision on the surface, but in fact the damage to the internal tissues of the breast is similar to that of traditional surgery to remove the lesion.
