Development of a Laparoscopic System for In Vivo Observation of the Bonghan Structure

Schematic diagram of the laparoscope to search for the Bonghan structure. The whole system is set on an optical table to minimize any external movement during the operation.

Illustrations for the connection between the borescope and the CCD (A). The staining dye is dropped through the rubber hose by using a syringe (B). Photograph of rat experiments with the laparoscope (C). The tip of the bore was inserted into the incised skin of the abdomen, and a manipulator was used to lift the skin.

Images from the laparoscopic system. The visualizing process is shown for the use of staining dye, trypan blue, in rat experiments. The process follows the direction of the arrows.
