Endotrainers are used in medical schools, residency programs, and surgical training centers to educate medical students, residents, and practicing surgeons. They allow surgical trainees to practice basic laparoscopic surgical skills without the pressures of the operating room. 

Endotrainers can simulate intracorporeal knotting, anastamosis, layered closure, dissection, and extracorporeal knotting. They can also be used to train and assess surgical skills in hysteroscopy and cystoscopy. 

Endotrainers are economical, lightweight, and have an abdominal shape. They also have various ports for the surgeon and assistant.
