Abstract

To meet the needs of real-time imaging in intraoperative microsurgical vessel anastomosis and to break through the bottleneck of limited penetration depth caused by absorption and scattering from blood, we present a novel design of three-view cooperative scanning handheld OCT probe. It is based on a low coherence source with 1.3μm central wavelength for extra-vascular imaging. Traditional OCT probe always scan from one direction and suffers from the problem of incomplete cross-sectional view of the vessel under investigation. We've designed an MEMS mirror based OCT handheld probe, which can be used to generate cross-sectional images from 3 view directions to increase the field of view in the depth direction. In addition, to adapt to vessels of different sizes, we've also designed a micro-stage to be used together with the handheld probe to solve the hand-trembling problem. The rectangle scanning range is about 3 * 3mm in three-view, which can meet the imaging demands of most vessels. We believe that application of the probe will greatly improve the quality of micro-vascular anastomosis success rate.
