Technical Field
[0001] The invention relates to the technical field of colostomy surgery demonstration instruments, and in particular to a colostomy teaching demonstration and operation practice model. Background Art
[0002] Ostomy refers to a surgery in which a section of the intestine is pulled out of the abdominal cavity for treatment purposes, and the opening is folded and sutured to the abdominal wall. The main purpose of enterostomy is to excrete intestinal contents, relieve intestinal pressure, protect the distal intestine, and promote the healing of intestinal diseases. Among them, it is necessary to surgically remove the lesion, separate the intestine, and flip one end of the intestine and sew it to an opening formed by the abdominal wall. Since enterostomy surgery requires certain operating experience to be performed, and the current ostomy surgery training is generally learned through PPT courseware and on-site surgical process visits, although more ostomy knowledge can be learned, most of it is some theoretical operating knowledge, which is not of much benefit to actual operating experience.
