Abstract

The invention provides a respiratory OCT (optical coherence tomography) catheter, comprising a fiber connection part connected with an optical fiber. A fiber signal is transmitted to the optical fiberthrough the fiber connection part. The fiber connection part comprises a connector, a fixator, a sealing component, a wire guide component and a fiber interface; the wire guide component sleeves theoptical fiber that is connected with the fiber connection; one end of the wire guide component is nested in the fiber interface that is connected with a fiber coupling of a driving device; the fiber coupling is nested in the connector that is nested in the fixator; one end of the fixator is nested in the sealing component; the wire guide component is passed sequentially through the connector, thefixator and the sealing component. An SC-SC fiber coupling of a driving module is connected with an SC (square-connector) fiber interface herein; a guide wire of small diameter is used; therefore, therespiratory OCT catheter for medical use is applicable to higher-order spatial narrow orifices, is more widely applicable and is easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an airway OCT catheter. Background technique [0002] Optical Coherence Tomography (OCT) is a high-resolution imaging technology, which is based on the principle of low-coherence light interference and combined with confocal microscopy technology, which can detect the weak coherence of incident weak coherence in different depth layers of biological tissue. The time delay and echo intensity signal of the backscattered wave of light can be scanned to obtain the two-dimensional or three-dimensional high-resolution microstructure of the sample, so as to obtain the in vivo non-destructive tomographic image of the measured sample. [0003] Using OCT imaging technology for 360° scanning detection can effectively obtain images of lumen tissue, but the existing OCT catheter products are too large to enter narrow lumens such as higher-level respiratory tracts, which limits the inte...
