Combined endoscope catheter and imaging system

The utility model discloses a combined endoscope catheter and an imaging system, which comprise an imaging optical fiber bundle, an imaging lens group focused on the end face of one side of the imaging optical fiber bundle, and a protective sleeve sleeved on the peripheral side of the imaging optical fiber bundle, and the imaging optical fiber bundle comprises a confocal optical fiber and a wide-field imaging catheter. The wide-field imaging conduit comprises a wide-field illumination optical fiber and a wide-field imaging optical fiber which are coaxially arranged, one end of the protective sleeve is connected with an end cap, the imaging lens group is located in the end cap, the imaging lens group comprises a wide-field imaging group and a confocal imaging group, the working distance of the wide-field imaging group is millimeter-scale, and the working distance of the confocal imaging group is micron-scale. The whole endoscope catheter can realize two imaging modes of wide-field imaging and confocal imaging
