The McMurdo vacuum-assisted minimally invasive breast biopsy system was developed by Dr. Burbakn, Parker and Fogarty in the United States and has been used in clinical practice. It is the most advanced biopsy device developed by Johnson & Johnson and is easy to operate and very precise, and is mainly used for biopsy of breast lumps and minimally invasive excision of benign tumors. The disadvantages of traditional open surgery to remove benign breast diseases are large trauma, long healing time, leaving multiple large scars on the breast, and treatment errors may also lead to breast deformity, which seriously affects aesthetics. For microscopic breast masses that are not clinically accessible, open surgery is even more difficult to remove. The advantages of minimally invasive removal of breast masses including fibroadenomas, hyperplastic nodules, and breast cysts are obvious compared to open surgery: less trauma, shorter healing time, smaller scars, and most patients do not develop wound infections. Removal of small masses has the absolute advantage of shorter operation time, less bleeding and less trauma.
