Initial trial of a stereoscopic, insertable, remotely controlled camera for minimal access surgery

摘要

Background Although video-laparoscopy has enabled successful minimal access surgery, the nature of the technology causes many troublesome limitations: (1) the fulcrum effect of the insertion site through the abdominal wall limits the angle of view, (2) the camera operator must use counterintuitive movements, (3) the laparoscope occupies an incision which otherwise could be used for an instrument, and (4) the laparoscope provides a two-dimensional image.
