An endoscope with a rigid inserted portionangulus iridocornealis for the visual examination and treatment of the abdominal/retroperitoneal cavity and its organs. It is inserted through an incision made in the abdominal wall (routinely just below the umbilicus) during laparoscopy. Anatomical images are transmitted to the user by the device through relayed lens optics or a fibreoptic bundle. The abdominal wall is distended, typically using a gas, providing the space to allow the surgeon to view and/or operate on the exposed organs. This reusable device is commonly used to evaluate/treat abdominal or pelvic pain, ectopic pregnancy, ovarian cysts, appendicitis, and perform female sterilization.
