An endoscope with a flexible inserted portion intended for the visual examination and treatment of the choledoc, better known as the common bile duct (CBD). Also known as a cholangioscope, it is inserted into the body through an artificial orifice created by an incision in the abdomen (laparoscopic technique) or introduced via a flexible duodenoscope during the procedure called choledochoscopy. Anatomical images are transmitted to the user by a video system with an image sensor chip at the distal end and the images showing on a monitor. This device is commonly used to examine structures of the CBD and for the removal of stones. This is a reusable device.
