Embodiment Construction

[0013] A monitoring system for an operating microscope proposed by the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in very simplified form and use imprecise ratios, which are only used for the purpose of conveniently and clearly assisting in describing the embodiments of the present invention.

[0014] The core idea of ​​the present invention is that the surgical microscope monitoring system provided by the present invention transmits the original laser speckle image captured by the CCD camera to the computer, and the computer calculates the original laser speckle image data to obtain the blood flow distribution image, which can real-time quantitative Obtain blood flow information with high spatial and temporal resolution. The operating m...

Abstract

The invention provides an operating microscope monitoring system which comprises an operating microscope, a laser lighting module, a charge coupled device (CCD) camera, a computer and a light filter. The laser lighting module comprises a laser diode and a laser diode driver connected with the laser diode, wherein the laser diode is connected with the operating microscope. The CCD camera is connected with the operating microscope. The computer is connected with the CCD camera in a telecommunication mode. The light filter is arranged in an imaging path of the CCD camera. Based on a transitional microscope and a laser speckle contrast imaging technology, the operating microscope monitoring system performs real-time monitoring to blood flow and blood vessel changes in operation through the laser lighting module and the CCD camera, achieves quantitive real-time monitoring of blood flow, distinguishing of arteries and veins and timely finding of abnormal blood flow situations in the surgical operation, facilitates the operation, timely finding of problems and measure adoption and can avoid unexpected injury of important blood vessels in the operation.

Description

technical field [0001] The invention relates to the technical field of biological tissue blood flow imaging, in particular to an operating microscope monitoring system. Background technique [0002] During surgical operations, intraoperative blood flow and blood vessel monitoring are crucial. Changes in local blood flow are of great significance for judging the changes and prognosis of surgical patients. During aneurysm clipping or vascular bypass grafting, monitoring of cortical blood flow can help assess whether blood flow has returned to preoperative levels. In addition, functional imaging of blood flow through the cortex can be performed to localize motor and sensory areas. [0003] However, there are not many methods that can obtain blood flow images in real time without interference during the operation. Currently, indocyanine green (ICG) angiography is commonly used in neurosurgery, which is an intraoperative monitoring technique for evaluating blood flow in cerebr...
