Minimally invasive surgery is one of the new and high-tech achievements in clinical medicine field. The representative of minimally invasive surgical instruments is endoscope. For example, a keyhole-sized hole or a tiny incision can be used to carry out various surgical operations, such as abdominal visceral lesion resection, deformity correction, repair or reconstruction, and finally achieve the purpose of treatment.
The difference between the minimally invasive surgery and the traditional surgery lies in that the former can reduce the area of surgical wound, avoid infection caused by large-scale exposure of body tissue, make patients recover faster, shorten their hospital stay and reduce medical costs.
Minimally invasive surgeries are very popular widely. In addition to the advanced electronic imaging diagnosis technology (such as CT, MRI ), minimally invasive surgery instruments can minimize the internal trauma caused by traditional surgeries. Therefore, foreign medical researchers believe that minimally invasive surgery is a "cross-century milestone". For example, the laparoscopic can be used to remove gallbladder lesions and other complex operations, such as partial hepatectomy, gastrectomy, and enterotomy. Also, most patients after the minimally invasive intra-abdominal surgery by laparoscope have good prognosis and few sequelae.
Nowadays, the new endobag laparoscopy (also called TV laparoscope) which is directly connected with the electronic imaging system has emerged.
The presence of such endoscope enables many abdominal operations such as gynecological operation, intracerebral operation and ophthalmic microsurgery.
