1.Principle of mirror axis: Laparoscope, target and monitor constitute the central axis of the entire operation. Personnel stations and puncture holes should be designed and implemented around the central axis.
2.The principle of flat elbow standing: adjust the operating table so that the height of the anterior abdominal wall of the patient after pneumoperitoneum is equal to the surgeon’s 90-degree elbow flexion, which can minimize the surgeon’s fatigue during operation and is most in line with the basic principles of ergonomics.
3.The principle of equal length of upper limbs: the length of the various cables on the operating table (suction lines, electrosurgical cables, optical cables, camera cables, etc.) above the fixed point is the same as the length of the surgeon’s upper limbs, roughly equal to the surgeon’s height minus 100 cm.
4.Triangular distribution principle: Laparoscopy and the operator's left and right hands operation holes are distributed as an inverted plane equilateral triangle as much as possible, and other auxiliary operation holes surround the core triangle. The holes are arranged flexibly according to the needs of the operation.
5.The principle of 60-degree intersection angle: the closer the intersection angle of the operator's left and right hands instruments to the target, the closer to 60 degrees, the more ergonomic principles are.
6.Bottom-up principle: Because the visual approach of laparoscopic surgery is 90-degree shift from the center of view of traditional open surgery, laparoscopic surgery usually starts from directly below the target and moves towards its front and back, And laparotomy usually starts from directly in front of the target and dissections from the front to the top of the target.
7.Gradient coagulation principle: When using electrosurgical equipment such as electrosurgical knife and ultrasonic knife to coagulate tubular tissue structure, the 6-8-10 coagulation technique can make the broken end form a longer protein coagulation gradient, and minimize the intraoperative and There is a risk of surgical complications due to the coagulation and shedding of the broken end caused by changes in the pressure in the lumen.
8.The principle of conservation of blood supply: When the main blood vessel of a target is smaller than ordinary people, you should be highly alert to the existence of its collateral, variant or perforating vessels.
9.The principle of progressive stages: laparoscopic surgery should be carried out in accordance with the principle of from easy to difficult, from simple to complex, and step by step. Don't make a real-time "Great Leap Forward" in the basic skills, otherwise it will fail the "satellite" and become a "shooting star."
10.The principle of overall optimization: Fully consider the actual condition of the patient, the skills of the surgeon and various objective material conditions, optimize the design concept and the purpose of the operation, optimize the anesthesia and operation methods, and optimize the application procedures for each patient.
