Ideal Laparoscope in Laparoscopic Surgery
4 months ago
Shadow is one of the important depth cue in minimal acceess surgery to improve the task performance of operating surgeon. An optimal shadow casting image with 20 to 30% contrast substantially increases the task performance in Minimal access surgery at it should be used to improve the efficiency of the operating surgeon. Fibre-optic light bundles can be deployed inside a super-elastic diverging shape memory alloy tubes to provide ceiling shadow-casting illumination. Such system also provides a balance between illumination and shadow contrast. Further research is required to develop the ideal shadow-producing video-endoscopic system.
