title: A Hand-held Instrument for in vivo Probe-based Confocal Laser Endomicroscopy during Minimally Invasive Surgery.
abstract: Probe-based confocal laser endomicroscopy (pCLE) provides high resolution imaging of tissue in vivo. Maintaining a steady contact between target tissue and pCLE probe tip is important for image consistency. In this paper, a new prototype hand-held instrument for in vivo pCLE during Minimally Invasive Surgery (MIS) is presented. The proposed instrument incorporates adaptive force sensing and actuation, allowing improved image consistency and force control, thus minimizing tissue deformation and induced micro-structural variations. The performance and accuracy of the contact force control are evaluated in detailed laboratory settings and in vivo validation of the device during transanal microsurgery in a live porcine model further demonstrates the potential clinical value of the device.
