“…Generally, it can only be available for single-person training, so they are no longer sufficient for an advanced laparoscopic training course. Live animal experimentation is still the most acceptable platform for laparoscopic simulation training, but laparoscopic training usually adopts medium to large animals that are closer to human anatomies, such as pigs and dogs, so it needs to be conducted in a qualified animal laboratory, equipped with clinical laparoscopic equipment, instruments and anesthesia support, including pneumoperitoneum, vital monitor, and anesthesia machines [ 27 , 28 ]. Therefore, the single training cost of live animal experiments is relatively high, and it cannot completely cover all stages of laparoscopic training and involves animal ethical issues and risks associated with the administration of anesthetic drugs [ 29 ].…”
