Laparoscopic surgery is a new minimally invasive method, which is an inevitable trend in the future development of surgical methods.With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a firm foundation for new technologies and methods.Moreover,by the increasingly sophisticated operation of doctors, many of the past open surgery has now been replaced by endoscopic surgery, greatly increasing the choice of surgery. The traditional method of laparoscopic surgery is to make three small incisions of 1 cm at the patient’s waist. Each is inserted by a pipe-like channel called "Trocar", which will be carried out through these three pipelines.The following procedures are made by using a special lengthened surgical instrument under computer monitoring as that of a open surgery.
The advantages of laparoscopic surgery by the two-hole method is very obvious. At first,it is a very small trauma, only two small cut with small scar, so it is more popular for young people and beauty-conscious women. Secondly, the surgery is a one-knife access, minimizing the damage to the surrounding tissue and lessening the chance of postoperative adhesions. Thirdly, the patient's postoperative wound pain was significantly reduced. Fourthly, the time of hospitalization is relatively shortened. Some patients can be discharged within 2-3 days and they can be fully recovered and put into work within 7 days. As a result, the burden on patients is greatly reduced and the hospital bed turnover rate is accelerating.
The laparoscopic surgery by the two-hole method is currently used in the following urological treatment, such as renal cyst excision,testicular dropping of cryptorchidism, high ligation of spermatic vein and so on.
