Description

A rotating side-scanning OCT ocular endoscope structure

Technical Field

The invention relates to the technical field of OCT ocular endoscope structures, and in particular to a rotating side-scanning OCT ocular endoscope structure.

Background Art

In the clinical application of endoscopes, the cross-scale imaging of the fiber scanning imaging system is usually achieved by combining the scanning motion of the fiber probe with the mechanical motion of the probe relative to the vertical axis of the scanning plane. On the scanning plane, the probe can usually obtain an image of μm size. The view of this scanning plane can be obtained through image processing algorithms such as graphic stitching. Combined with the cm-level mechanical motion of the probe, the cross-scale stereoscopic image of the cm-level channel observed by the endoscope is restored through the image algorithm, and the part to be observed can be selected for microscopic observation. The fiber scanning imaging technology used in the fiber scanning imaging system refers to the technology of controlling the optical fiber and its emitted light beam deflection to make the optical fiber move along a predetermined trajectory and collect stray light imaging while scanning. The way to control the optical fiber is completed by combining physical actuation effects such as piezoelectric materials, micro-electromechanical or electrothermal with control signals. The image obtained by imaging a single optical fiber has high resolution, but the field of view is extremely small. These high-resolution microscopic images are obtained by using optical fiber imaging bundles and microlenses to transfer light between tissues. In actual use, high-resolution large-field images are usually obtained by image stitching multiple images obtained by moving the optical fiber along the scanning trajectory.

At present, many cross-scale optical endoscopic imaging technologies are still in the research stage or their application scenarios are still relatively limited. For example, the cross-scale zoom optical system using new lenses such as liquid lenses has not yet been industrialized due to the processing technology. Another example is the cross-scale OCT scanning endoscopy probe system for lower gastrointestinal imaging, which still has many problems to be solved. With the in-depth research in basic disciplines such as biomedicine, the influence of the development of computer science and advanced manufacturing and processing industries, these cross-scale optical endoscopic imaging technologies that are still in the research stage are gradually maturing, and the further development of existing cross-scale optical imaging technologies, endoscopic cross-scale optical imaging technology will inevitably have a revolutionary development and broader application prospects.

With the increasing maturity of optical coherence tomography (OCT) technology, it has become possible to combine OCT technology with endoscopes, and the combination of OCT and endoscopes has further expanded the application scope of OCT technology. Therefore, the design of the fiber optic scanning probe determines the application and development of OCT endoscopes. Currently, OCT endoscopes used in clinical medicine generally have the characteristics of fast scanning speed, good flexibility, and miniaturized size. According to different scanning methods, OCT endoscopes can be divided into side scanning probes and forward scanning probes. Among them, the side scanning probe is the earliest to appear. This probe combines optical fiber, A self-focusing lens (Green lens), a reflecting prism, and a micro-motor are installed in a glass tube and combined with an endoscope to penetrate into human organs. The micro-motor drives the probe to rotate to scan the side wall. The existing OCT eye endoscope structure is generally not conducive to multi-functional steering movement during scanning, which affects the scanning range and clarity of the optical fiber bundle during focus adjustment. It is not convenient to compare and analyze the data scanned by the OCT eye endoscope under multiple sets of data. It is easy to scan the entire area back and forth, which has a significant impact on the diagnosis, treatment and monitoring of ophthalmic diseases by ophthalmic surgeons.
