Description

Appendectomy model

Technical Field

The invention belongs to the field of medical supplies, and discloses an appendectomy model.

Background

The appendix, also known as the vermicular cast, is a slender, curved cecum, located between the cecum and ileum at the lower right of the abdomen, and its root is attached to the posterior medial wall of the cecum. 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. Appendectomy is used for treating acute appendicitis, and generally has the advantages that the operation is easy, but the appendectomy cannot be regarded as a 'minor operation', and high attention must be paid to improve the treatment effect and avoid or reduce postoperative complications and sequelae.

The problems of the prior art are as follows: for a new person, the operating skill of the appendectomy operation must be mastered by continuous practice, but most of currently used appendectomy models are simple in structure, all parts are not strictly distinguished and displayed, the used materials are different from the human body, the structure of the human body cannot be truly simulated, and the actual and intuitive feeling and the remarkable skill improvement cannot be obtained when appendectomy is practiced on the model.
