I. Minimally invasive surgery Breast lumps, especially benign breast lumps, are mostly found in young and middle-aged women, most of whom play an important social role and are not only worried about the lumps becoming cancerous in the breast, but also about whether they will leave unsightly scars after surgery. The emergence of “Ankor” minimally invasive surgery has met the desire of women to solve breast lumps with minimal trauma. The “Ankle” minimally invasive surgery is a special surgical procedure guided by ultrasound, during which the surgeon will monitor the entire procedure under the ultrasound screen. The procedure requires only a 3 mm incision on the breast surface, local anesthesia, and the insertion of a specially designed rotary cutter to aspirate the lump from the breast. For multiple ipsilateral masses, the minimally invasive procedure requires only one incision and leaves no visible scarring after surgery, usually only a puncture site the size of a red mole. The removed tumor specimens can also be used for pathological examination, which also solves the problem of postoperative pathological confirmation. Due to the limitation of equipment, minimally invasive breast surgery is currently only applicable to small lumps under 2.5 cm. The operation time: about 10 minutes for each lump, and the operation time will be gradually extended as the number of lumps increases. The latest generation of minimally invasive breast surgery equipment, produced by SenoRx, was first successfully developed and used in China in 2009. (2) More precise Special device, can remove small tumors and superficial tumors close to the skin Superficial tumors near the skin can hardly be performed (3) Cleaner Multiple cutting angles are available, computer-controlled, will not miss the cut, lump removal more clean and thorough Only manual rotation of the knife handle, easy to miss the cut (4) Safer Fully automatic, fully enclosed, continuous and rapid cutting lumps, short operation time, less bleeding Semi-automatic sampling, long operation time, more bleeding. (5) More economical One blade can continuously cut multiple masses or larger tumors, which is less expensive. Generally, two or more blades are required for larger masses (about 4,000 yuan per blade). (1) Patients with benign lumps, tumor size ≤ 2.5 cm, especially for patients with multiple lumps in one breast. (2) The diagnosis is unclear and biopsy is needed to clarify the diagnosis of benign and malignant masses. 2. Contraindications: (1) Patients with disorders of coagulation mechanism. (2) Various types of hemangioma. 3.Pre-operative precautions: (1) Avoid menstruation as much as possible. (2) Preoperative routine blood and coagulation tests to ensure the safety of surgery. 4.Post-operative precautions: (1) Compression bandage should be applied for about 48 hours after surgery. (2) Take oral or intravenous antibiotics to prevent infection. (3) Three months after surgery, you should return to the hospital for a follow-up examination.
