With the rapid development of medical technology, minimally invasive surgery with its advantages of small trauma, fast recovery, fewer complications and other advantages quickly accepted by the people, minimally invasive surgery is also more and more widely used in clinical practice. At present, our department in the thoracoscopic minimally invasive surgery on the basis of double-operated holes, exploring single-operated holes in the surgery has made great progress, because of the surgical trauma in the double-operated holes on the basis of a reduction of one operated hole, reducing the surgical incision, trauma It has been highly praised by patients and friends for its smaller trauma, faster recovery and more beautiful appearance after surgery compared with the double-operated hole. Li Mingzhu, Department of Thoracic Surgery, Hebei Provincial Chest Hospital At present, our department further improves the surgery on the basis of minimally invasive thoracoscopic double-operating hole surgery by changing the classic two-operating holes to one-operating holes, and the number of incisions is changed from three to two, which reduces the trauma of the surgery, increases the beauty of the skin after the surgery, and is more easily accepted by patients and friends. During lobectomy, a small incision of about 1.5M is made from the eighth intercostal space of the mid-axillary line, and the thoracoscopic light source is inserted through this hole. An operating hole of about 3M is made from the fourth or fifth intercostal space in the middle of the nipple line and the anterior axillary line, and operation is performed through this hole to complete the lobectomy, and the total length of the skin surface incision is about 5M, which greatly reduces the surgical incision and the trauma of the operation. It makes the postoperative recovery of the patient faster, with fewer complications and more beautiful.
