SURGICAL IMAGING SYSTEMS

摘要

Systems, methods and devices are provided for illuminating tissue with monochromatic or broadband light and imaging light that has been reflected back from the tissue. Imaging may be white-light imaging or hyperspectral imaging. The system can be a stand-alone hyperspectral imaging system, integrated as part of an external video scope, or as an auxiliary imaging module on an external videoscope. Various elements of a video scope that is particularly suited for minimally invasive surgery is first presented and then its configurations suitable for hyperspectral imaging are explained.

主权项

1. A hyperspectral imaging apparatus for performing hyperspectral imaging of a surgical field, the hyperspectral imaging apparatus comprising:
an illuminated exoscope comprising:
a longitudinal housing;an optical imaging assembly provided within said longitudinal housing;an imaging camera interfaced with said optical imaging assembly for detecting images collected by said optical imaging assembly; andone or more illumination sources supported by said longitudinal housing, wherein an illumination axis associated with each illumination source is offset from an imaging axis of said optical imaging assembly; a remote light source; a spectral filtering device in optical communication with said remote light source; and a light guide having a proximal end in optical communication with an output of said spectral filtering device and one or more distal ends, where each distal end is in optical communication with an illumination source.
