Johnson & Johnson is the world's largest medical equipment manufacturer. It has a history of more than 130 years and is famous for its production of high-tech and high-quality medical products. It successfully developed and launched the Mammotome vacuum-assisted minimally invasive breast rotational excision system in 1999, which can perform biopsy and complete resection of breast diseased tissue in a precise, minimally invasive and safe manner. 1. Characteristics of Mammotome Breast Surgery
1. Accurate positioning and accurate removal of lesions: Deep lesions and tiny tumors with a diameter of only 3 mm can also be accurately removed. In the past, although such tumors could be detected by ultrasound, However, clinicians cannot touch and locate the disease through palpation. They can only observe and wait for it to grow up before performing surgery or performing extensive resection.
2. The incision is small and the cosmetic effect is good: Compared with the 3-5 cm incision of traditional surgery, the incision of Mammotome surgery is only 2-5 mm, no sutures are needed, and no scars are left; and there are many breasts on the same side. Lesions can be removed through one incision (less than 3, the distance does not exceed 10 cm). It avoids incision of skin, subcutaneous tissue and normal glands, resulting in small tissue damage and fast recovery. The advantages are particularly obvious for patients with deep breast tumors and obesity.
3. High-tech design ensures safety: the unique hollow puncture needle design allows only one puncture during the entire operation to avoid needle tract transfer caused by repeated punctures that may cause tumor cells to fall off.
4. More accurate diagnosis: Biopsies of suspicious lesions can obtain large and continuous specimens. The sample volume taken by one puncture is 8 times that of traditional hollow thick needles, reducing the false negative rate of pathology by 50%. (Due to the small amount and limitation of the specimen, malignant tumor cells are not found and are misdiagnosed as negative); and a marking clip can be placed at the biopsy site to observe whether the lesion has malignant transformation at any time.
5. Low infection rate and more economical: The application of electrocoagulation to stop bleeding in conventional surgical incisions can easily cause fat liquefaction, and surgical sutures remain as foreign bodies in the incisions, which can easily cause incision infection and poor healing; Mammotome The operation causes little damage to normal tissues, no foreign matter remains in the human body, the risk of infection is significantly reduced, and the cost of anti-infection is saved.
6. The operation is fast and convenient: the operation time is short, the pain is mild, and can be performed in an outpatient setting. It only takes 10-30 minutes for a single tumor, and you can move freely after the operation.
2. Indications for Mammotome surgery
1. Benign breast tumors less than 3.5 cm, fibroadenomas, nodules, asymmetric density, multifocal lesions and microscopic Calcification.
2. Breast tumors (<3 cm) whose pathological nature is unknown and require excision and biopsy.
3. Contraindications of Mammotome surgery
1. Biopsy can be performed on patients with suspected breast cancer, but mass rotation surgery should be avoided;
2. Surgery is contraindicated for patients with bleeding tendencies, hemangioma and diabetes. For tumors located in the areola and with a diameter >3.5cm, rotational resection surgery should be performed with caution
