Multifunctional array optical coherence tomography probe

Abstract

The invention provides a multifunctional array optical coherence tomography probe which comprises a base body, an imaging probe assembly and an extended function component. A plurality of evenly-distributed through holes are formed in the imaging probe region in the peripheral direction of the base body, and the through holes are formed in the axial direction of the base body; a center hole is formed in the center axis of the base body in the extended region; the imaging probe assembly comprises a plurality of perpendicular emergent light collimators formed inside the through holes respectively and a plurality of refraction emergent light collimators, wherein the collimators are arranged in a spaced mode; emergent light of the perpendicular emergent light collimators are parallel to the center line of the center hole; the included angle formed between the center line of the center hole and the emergent light of the refraction emergent light collimators is 0-90 degrees; the extended function component is installed inside the center hole for observing the lesion surface layer portion in real time or performing ablation treatment. The problems that real-time observation cannot be performed and ablation treatment cannot be performed in the lesion region at the same time are solved while the lesion region can be detected comprehensively.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional array optical coherence tomography probe. Background technique [0002] With the development of science, various imaging instruments have appeared successively in medicine and biology, such as: ultrasound imaging, X-ray imaging, CT, MRI and PET, etc. These instruments have their own advantages and disadvantages. Disadvantages: [0003] Ultrasound imaging relies on the acoustic impedance of biological tissues, and the contrast is poor, making it difficult to detect early cancers; [0004] X-ray imaging depends on the density of biological tissue. The greater the density, the whiter the image. The images of different organs and tissues with similar densities cannot be distinguished due to low contrast, and X-ray perspective exposes the tissue to strong ion radiation. , the incident high energy will ionize the biological tissue. [0005] The use of CT, M...
