Microimaging

Recent technological advances in optics, imaging, and illumination have brought forth a new generation of miniature laparoscopes suitable for emergency laparoscopy. A simple comparative analysis was conducted to determine which optic would be most suitable in an emergent environment. Animal experiments were designed to emulate a videolaparoscopic procedure. Six telescopes were visually assessed as to sharpness, depth of field, brightness and displayed image size on the TV monitor. A videotape record was obtained. Two telescopes were perceived as clearly superior in the field. When they meet image specification, miniature laparoscopes can be useful in the emergency setting.
