One-stop BPA operation system based on three-dimensional OCT real-time imaging

Abstract

The invention provides a one-stop BPA operation system based on three-dimensional OCT real-time imaging, which comprises a scanning light source and light source driving module, a main interference module, a rotating and withdrawing mechanism module, a balance detection module, a data acquisition module, a work station and a catheter module, and is characterized in that the scanning light source and light source driving module is connected with the main interference module through a first optical fiber coupler; the main interference module is connected with a second optical fiber coupler through a first circulator, the second optical fiber coupler is connected with a data acquisition module through a balance detection module, and the data acquisition module is connected with the input end of a work station. A two-dimensional cross section image is reconstructed into a three-dimensional pulmonary artery blood vessel diagram through a computer reconstruction technology, the BPA operation curative effect is improved, operation complications are reduced, an OCT imaging system and a catheter special for pulmonary artery disease diagnosis and treatment are formed, and then more instant information of lesion parts can be provided for doctors.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to a one-stop BPA surgical system based on three-dimensional OCT real-time imaging. Background technique [0002] Optical coherence tomography (OCT) is the latest generation of intravascular imaging technology. Its principle is to use a fiber optic interferometer and a near-infrared light source that emits low energy and a wavelength of 1310 nm. Through catheter technology, the imaging fiber guide wire can be real-time and accurate. Evaluate the structure of blood vessels and provide two-dimensional cross-sectional images of blood vessels. The resolution of OCT is 10-20 μm, which can provide ultra-high-resolution images close to the histological level; [0003] Coronary artery related studies have shown that OCT is far superior to the traditional imaging mode in the morphological identification of plaque rupture, thrombus, thin-cap fibroatheroma and macrophages inside the fibrous c...

Problems solved by technology

[0004] However, there are still many problems in practical application, such as: (1) At present, OCT can only observe the structure in the pulmonary artery lumen before and after BPA operation, and cannot guide BPA in real time; (2) Repeated multiple operations , increase the operation steps and time, and cannot achieve one-stop operation; (3) The current OCT pulmonary artery imaging can only provide two-dimensional cross-sectional images of blood vessels, and it is necessary to combine the two-dimensional cross-sectional images with the anatomical The structure is mapped, so the present invention proposes a one-stop BPA surgery system based on three-dimensional OCT real-time imaging to solve the problems in the prior art
