Appendicitis is an inflammatory change caused by a variety of factors. It is a common disease in surgery. It is most common in young people, with more men than women. Acute appendicitis is more common clinically, and it can be affected by women of all ages and during pregnancy.

(1) Surgical instruments: Laparoscopic trocars and complete sets of surgical instruments are used. It can work at the same time of pneumoperitoneum, endoscopy, and operating equipment

(2) Surgical method: insert a laparoscope to establish a pneumoperitoneum with a trocar, use an ultrasonic knife to separate the appendix adhesions and treat the mesangium, use intraperitoneal ligation or absorbable clips to close the appendix stump (intra-abdominal resection), or drag the appendix Out, use conventional surgery to treat the appendix stump (drag-out resection).

The umbilicus is the only natural scar on the body. Endoscopic surgery through the umbilicus can not only achieve a seamless operation effect, but also avoid the risk of gastric leakage, intestinal leakage and abdominal infection caused by the puncture of the natural cavity endoscopic surgery. 

The use of a trocar for laparoscopy can greatly reduce the time for pneumoperitoneum operation and reduce the operation time. In addition, the sealing performance has also been greatly improved, reducing the occurrence of air leakage and making the operation more stable.
