Since it was applied in clinic in the 1980s, laparoscopic surgery has gone through the course from the treatment of benign diseases to the radical treatment of malignant tumors, and has been widely favored by patients due to its characteristics of less pain and quicker recovery than the traditional open surgery. Currently, laparoscopic surgery, which leads the concept of minimally invasive surgery, has realized the progress from “multi-hole” to “single hole”. Traditional laparoscopic surgery requires 3 to 5 surgical holes in the patient’s abdomen, each hole is about 0.5 to 1 centimeter, and the surgeon uses special instruments to enter the abdominal cavity of the human body through these holes to complete the relevant surgery. The latest “single-hole laparoscopic” surgery, can be all the instruments, including cameras, light sources, special scalpels, etc. are concentrated in a hole, through the navel or umbilical cord into the body to complete the operation. After the surgery, the folds of the umbilical skin can cover the incision, thus achieving a scarless effect, which has been internationally recognized as the most feasible “scarless” technology at this stage.
