| Research Abstract |
Laparoscopic surgery has become more popular with many postoperative benefits for patient. In laparoscopic surgery, however, the cooperation between a surgeon and a camera assistant is important, because the surgeon's view field is relegated to the camera assistant. It may be better that a robotic hand is well developed and manipulates a laparoscope more effectively than camera assistant to show a target as the surgeon aimed. In this study, we developed a simple and small positioning system for laparoscopic camera that is manipulated by the surgeon's viewpoint on the imaging monitor for reducing his effort with camera control. This system is composed with eye point detection system, micro-controller(PIC), linkage mechanism and two stepping motors. The control signals to the system are analogs with voltage that indicate coordinate values of the eye point on the imaging monitor. The motor controlling program is described with assembly language for effective and fast positioning of the camera. Our experimental results show the effectiveness and potentiality with this camera positioning system controlled by the surgeon's viewpoint on the imaging monitor.
