Design of a Stereo Handheld Camera Tool for Single Port Laparoscopy

摘要

SPL (Single Port Laparoscopy) might bring improved surgical outcomes but this new procedure needs effective and functional next-generation surgical tools. Although several robotic systems for SPL have been constructed, only manual SPL tools are currently used in clinical SPL procedures. This paper presents the design, construction and experimental characterizations of a stereo handheld camera tool with integrated illumination for SPL. The camera tool can be folded for the insertion into abdomen through a 012mm trocar. Besides providing 3D visualization and illumination of the surgical scene, it can also be unfolded to spare an additional access port for other surgical tools. The actual effectiveness of this camera tool could be further gauged in a surgical setting with other manual SPL tools.
