Background

Minimally invasive medicine is the leading development direction of medical science and technology, and minimally invasive surgery represented by laparoscopic surgery has gradually replaced traditional open surgery. It is an emerging technology which is gradually developed in the later 20 th century. Since the 90 s of the 20 th century, laparoscopic surgery has progressed rapidly and is now widely used to treat a variety of diseases in general surgery, obstetrics and gynecology, and urology. Traditional laparoscopic surgery usually needs 3-6 puncture holes to complete, and increasing the puncture holes means increasing potential complications such as hemorrhage, hernia of the puncture hole, visceral injury and the like, and affecting the beautifying effect of the abdominal part after the surgery. How to enable abdominal surgery to be successfully completed with minimal or no abdominal incision has been a goal sought by surgeons.

Compared with the conventional three-hole laparoscopic surgery and four-hole laparoscopic surgery, the single-hole laparoscopic surgery has the greatest advantages of small abdominal wall wound, light postoperative pain, hidden surgical scar which is difficult to discover and satisfactory cosmetic effect besides the basic therapeutic effect, and is gradually becoming the mainstream of the abdominal cavity minimally invasive surgery. In the single port laparoscopic surgery, since the laparoscope and the surgical operating instruments are concentrated in a narrow space of a patient, it is more difficult to effectively expose the surgical field than in the conventional laparoscopic surgery; and the disappearance of the angle between the operation instruments is not beneficial to the traction and exposure of the operation part, which seriously influences the operation effect of the doctor, greatly reduces the operation efficiency of the doctor and needs to be improved urgently.
