Description
Technical Field
The invention relates to medical equipment for teaching, in particular to a simulation trainer for anorectal NOTES endoscopic surgery.
Background
Endoscopic surgery via the natural orifice (naturalorifice transluminal endoscopic surgery, NOTES) is an emerging minimally invasive surgical technique. NOTES refers to surgery performed by endoscope through natural ducts of the human body, such as stomach, vagina, bladder, colon, rectum, etc., without incision of the body surface skin. Compared with the traditional open surgery and laparoscope, NOTES has the advantages of no visible surgical scar, reduced intra-abdominal adhesion, small surgical trauma, less postoperative pain, quick recovery and the like. In particular, the trans-anal full-straight mesentery excision (taTME) solves the problems of traditional low-level rectal cancer operation, from top to bottom, when men suffer from prostatic hypertrophy, pelvic stenosis, obesity and the like, the distal rectum is difficult to expose due to the existence of sacral tail bending, the tumor positive and nerve injury of a distal incisal margin and a ring Zhou Qieyuan are easy to cause, and the taTME operation adopts free operation from bottom to top, so that the distal rectum and accurate excision can be more directly exposed. However, the reverse operation of the taTME surgery is a new anatomical path, and new anatomical marks need to be paid attention to improve the safety of the surgery and shorten the learning curve. For training of a novel technology, the best learning process is theoretical teaching and autopsy, but the technology is harder to master than the conventional endoscopic surgery, and the fresh frozen autopsy available for endoscopic surgery at home and abroad is limited at present, so that the cost is high, and the teaching of low-annual-cost doctors and medical students is difficult to be limited in practice before the taTME surgery is performed on actual human bodies.
