Transanal NOTES endoscopic surgery simulation trainer

Abstract

The invention discloses a transanal NOTES endoscopic surgery simulation trainer. The trainer is formed by an operation box, a shooting video system, a task training module, and a matched accessory including an anorectal laparoendoscopic single-site surgery puncture device, a surgical annular retractor and a transfixion device, the entrance of a body surface channel and a minimally invasive deviceinsertion channel to a simulation orifice and a surgical position can be simulated, and training of surgical technologies including suture, separation and ligation of a simulation surgery area is performed. According to the transanal NOTES endoscopic surgery simulation trainer, the blank of the transanal NOTES simulator is filled in, various special training modules are designed according to transanal NOTES surgery characteristics, the transanal NOTES endoscopic surgery simulation trainer is applicable to development of transanal NOTES surgery skill training and practice for clinical hospitals, medical skill training mechanisms and medical academies, and the transanal NOTES endoscopic surgery simulation trainer is advantaged by low cost and easy promotion.

Description

technical field [0001] The invention relates to medical equipment for teaching, and more specifically relates to a transanal NOTES laparoscopic surgery simulation trainer. Background technique [0002] Naturalorifice transluminal endoscopic surgery (NOTES) is an emerging minimally invasive surgical technique. NOTES refers to the use of an endoscope to enter the body cavity through the natural orifices of the human body, such as the stomach, vagina, bladder, colon, and rectum, without incision on the body surface. Compared with traditional laparotomy and laparoscopy, NOTES has the advantages of no visible surgical scar, less intra-abdominal adhesion, less surgical trauma, less postoperative pain, and faster recovery. In particular, transanal total mesorectal excision (taTME) solves traditional low rectal cancer surgery. It is operated from top to bottom. When encountering male prostatic hypertrophy, pelvic stenosis, obesity, etc., due to the existence of sacrococcygeal curva...

AI Technical Summary

Problems solved by technology

For the training of a new technology, the best learning process is to teach the theory first, and then conduct autopsy, but the technology is more difficult to master than conventional laparoscopic surgery, and the fresh frozen corpses that can be used for laparoscopic surgery at home and abroad are limited and expensive , making it difficult for junior doctors and medical students to teach in the actual human body and restrict the preclinical practice of taTME surgery
