Minimally invasive breast surgery is usually referred to as the McMurtagh Breast Mass Rotational Excision, which utilizes a minimally invasive rotational excision needle by connecting it to a vacuum negative pressure suction device, which allows for the removal of the mass while suctioning the bleeding in the operative cavity, with the advantages of small incisions, no impact on breast shape, quick recovery and less bleeding after the procedure. The specific procedure of minimally invasive surgery is: 1. The patient first lies on the surgical bed and may need to change position depending on the location of the lump. 2. After the position is set, local anesthesia is injected around the lump to avoid pain during the operation. 3. After the skin is sterilized, the surgeon uses a blade to make an incision of about 3 to 5 mm in the entry position, and then the minimally invasive rotary scalpel is inserted through the incision, while the ultrasound is used to check whether the rotary scalpel is located in the surrounding area of the mass. 4. Once the rotary scalpel is in place, the mass is excised. Depending on the size and location of the mass, 10 to 20 excisions may be required. 5. When the excision is determined to be clean using ultrasound, the rotary cutter is removed, the skin is sterilized again, the wound is covered with sterile gauze, and the chest is wrapped around with an elastic bandage for pressure. The excised tissue is sent to the pathology department for examination. The above is the whole process of minimally invasive surgery. The operation of different hospitals varies, and it is recommended to choose a hospital with professional qualifications for treatment.
