Serving as minimally invasive surgery, robotic surgery has become a promising treatment approach toward various
diseases, such as Urology, Gastroenterology, or Gynecology. Although robotic surgery exhibits several advantages of
decreasing the incision size and shorter patient stay, it still imposes extensive labor loading to the surgeons. Therefore,
recently, semiautonomous laparoscope surgery has been emerged to improve the surgery precision further. In this study,
we have developed a miniature imaging head combing wide-angle camera and optical coherence tomography aiming for
semiautonomous laparoscope surgery. Leveraging the ranging information provided from OCT, it allows more agile
control of the imaging head.
Due to the complex geometry of the oral cavity, it is challenging to perform wide-field optical coherence tomography
(OCT) imaging of different regions of the oral mucosa, particularly in patients with opening difficulty due to submucosa
fibrosis. In addition to changes in the tissue architectures, angiogenesis has been demonstrated to play an important role in
the progression of oral neoplasm. In this study, we have developed a micromotor imaging catheter allowing high-speed
and wide-field OCT and OCT angiography imaging of the oral mucosa. Leveraging polarization diversity detection, it
ensures an optimal detection of the OCT signal for the entire circumference.
