Single-fiber endoscopic system

The invention discloses a single-fiber endoscopic system. The system comprises an integrated optical coherence tomography module and a fractional flow reverse detection module, and the integrated optical coherence tomography module is connected with the fractional flow reverse detection module through a fiber; and the integrated optical coherence tomography module includes an endoscopic probe unit, and the endoscopic probe unit includes an annular flexible tube, a fixed bearer, an elongated single fiber, a first magnet, a second magnet and a lens. The optical coherence tomography module and the fractional flow reverse detection module are integrated in one system by using a characteristic that different magnetic fields apply driving forces in different directions to the above two magnets in order to make the optical fiber shift, so the consistency of a detection area is ensured, and the accuracy and the success rate of detection are improved. 本发明揭示了种单光纤内窥系统，包括集成光学相干层析模块和血流储备分数检测模块，所述集成光学相干层析模块与所述血流储备分数检测模块通过光
