The appendix, located in the lower right of the abdomen between the cecum and ileum, is an elongated, curved, blind tube, distal occlusive.

Appendicitis is an inflammatory change caused by various factors, is a common surgical disease, and is most common in young people, and more in males than females. Clinically, acute appendicitis is common and can be caused by women of all ages and in gestational period.

Common appendicitis treatment methods include appendectomy, which is used for treating acute appendicitis, suppurative appendicitis, gangrenous appendicitis and the like. The surgical procedure is generally easier, but sometimes more difficult, such as an ectopic appendix. Therefore, appendectomy cannot be considered a minor procedure in any way. Attention must be paid to improve the therapeutic effect and to avoid or reduce the occurrence of postoperative complications and sequelae.

With the development of minimally invasive surgery technology, the damage degree of appendectomy to a human body is gradually reduced, and the appendectomy can be completed without performing laparotomy by generally adopting an endoscopic surgery technology and using an appendix ligation device. However, in the endoscopic surgical technique of appendectomy, the lantern ring of the traditional appendix ligation device is in a free state in the process of entering a human body, so that the resistance of entering the human body is increased, a pneumoperitoneum channel with a larger diameter is established, the risk of interference with other instruments is increased, the surgical difficulty is higher, a doctor is required to have more experience, and the surgical cost is higher.
