Mammotome is a computer-controlled, vacuum-assisted, high-speed rotary breast therapeutic diagnostic device for the minimally invasive treatment or biopsy of breast lumps (tumors) under the guidance of ultrasound or molybdenum-palladium stereoscopic positioning. As it is able to implement minimally invasive excision treatment of the breast under image guidance, it is able to remove breast abnormalities that are clinically inaccessible or difficult to remove surgically, greatly improving the diagnostic accuracy of early breast cancer. After the removal of a breast lump with McMurtry, not only the external scar is small, but also the internal scar is small, which has little effect on the diagnosis of reoccurring breast lumps. The minimally invasive rotational mastectomy is characterized by accuracy, minimally invasiveness, and aesthetics. You can return to normal work and life the next day, avoiding the pain and damage to the breast shape of traditional open surgery, as well as the impact of internal scarring on future examinations and diagnosis. In conclusion, Mammotome Rotational Excision is a safe, effective and accurate method of minimally invasive breast treatment and diagnosis. Indications for Mammotome surgery: breast fibroma, breast nodule, breast microcalcification, breast asymmetric density, breast multifocal lesions. Introduction of Mammotome System The Mammotome System, manufactured by Ethicon Endo Surgery, is an advanced breast biopsy system, which can be used to excise suspicious lesions of the breast through 2-3mm puncture holes, and to obtain reliable pathologic and histologic specimens. It is an advanced breast biopsy system, which can remove all kinds of benign tumors through 2-3mm puncture holes and obtain reliable pathological and histological specimens. It is characterized by minimally invasive and accuracy. Minimally invasive – Unique design of the puncture needle. Casing needle and rotary cutter, can be placed to mark the clip, a single puncture, can be sampled more than one specimen, at the same time to reduce the possibility of tissue residue needle channel; puncture fast and easy, reduce the needle channel damage; 2-5 mm incision; no need for sutures, reduce the internal and external scars of the breast in order to facilitate postoperative follow-up, to maintain the aesthetic appearance of the breast. Accuracy – Vacuum-assisted obtains a large and continuous specimen, making the diagnostic accuracy greatly increased. Second, the indications and significance of breast tissue biopsy 1, the significance of biopsy: tissue biopsy is the main means of confirming the diagnosis of breast disease. 2, the indications for biopsy: lump in the breast; molybdenum target X-ray found suspicious tiny calcification or dense block shadow; ultrasound found in the breast mass 3, biopsy methods and advantages and disadvantages: open surgical biopsy: large amount of specimen, diagnostic accuracy; excision of more breast tissue, a larger skin incision scar, destroying the aesthetics of breast. Fine needle aspiration biopsy: small amount of specimen, poor diagnostic reliability. Coarse needle aspiration biopsy: larger specimen volume, higher diagnostic accuracy of pathology, requiring multiple punctures, with certain underestimation and leakage rates. McMurtry puncture biopsy: It is an advanced minimally invasive breast biopsy system, which provides a more accurate and minimally invasive method for the diagnosis and treatment of breast lumps Its diagnostic accuracy is much higher than that of crude needle puncture. The diagnostic accuracy is much higher than that of crude needle aspiration. It has the same accuracy as open surgical biopsy, but is more minimally invasive and does not damage the aesthetic appearance of the breast. Mammotome superiority Minimally invasive, local anesthesia; large amount of resection specimen, accurate pathological diagnosis; one puncture, multiple sampling; with ultrasound or molybdenum target localization system, accurate positioning, accurate resection; the next day you can engage in normal life and work; small skin incision (3mm), cosmetic effect is good; no breast tissue deformation.
