The invention relates to the technical field of
medical equipment and biomarker detection, and provides an
optical fiber biosensing probe for detecting a biomarker in a
biliary tract, the
optical fiber biosensing probe comprises a computer, a
spectrometer and a
light source, the computer is electrically connected with the
spectrometer, the
spectrometer is electrically connected with the
light source, the output end of the
light source is connected with a probe, and the surface of the probe is of a spiral structure; the probe extends into a
biliary tract system, the light source emits light with specific
wavelength and intensity, so that the light can reach the probe along the incoming
optical fiber, and a biomarker in the
biliary tract is specifically combined with the surface of the probe, so that an optical
signal is changed and output through the outgoing optical
fiber; the
spectrograph can be used for carrying out detailed
spectral analysis on an optical
signal output from the outgoing optical
fiber, and the
spectral analysis comprises the characteristics of
wavelength, intensity, absorption peak and the like, so that in-vivo, rapid, accurate and stable detection on bile
protein in the biliary tract is realized; during bile detection, collection, storage and in-vitro detection are not needed, the
pollution deterioration possibility is small, and the in-vivo detection result is more real.
