Problems solved by technology
[0004] The above-mentioned fluorescence surgical navigation system is concentrated in the 700-900 nanometer range (the near-infrared region). In this range, the background fluorescence and scattering of living tissues are still relatively strong, which greatly affects the imaging quality and affects the real-time imaging of relevant clinicians. Judgment of the surgical method and the size of the boundary resection of the lesion based on pictures

The invention relates to a fluorescent surgical navigation system, in particular to imaging equipment. The imaging equipment comprises a hand-held and endoscope near-infrared imaging system and a building method. The imaging equipment comprises a display control end, an imaging group and a light source group, wherein the imaging group and the light source group are connected with the display control end, and an irradiation range of emergent light of the light source group is superposed with the imaging visual field of the imaging group; the light source group provides an excitation probe, so that the imaging group collects image information of a target and transmits the image information to the control end for displaying; and the display control end further controls the imaging group to work. The handheld near-infrared imaging system has the beneficial effects that on the basis of matching with a corresponding imaging probe, the handheld near-infrared imaging system can be used for real-time imaging of surface focus parts of laboratory animals and clinical patients, so that the functions of surgical navigation diagnosis and focus part excision are realized; and the light source group does not need to turn off an operating lamp in the navigation diagnosis process of a clinician, the whole navigation excision process can be performed under the light of the operating lamp, and the accuracy of focus boundary determination is improved.
Description
technical field [0001] The invention relates to a fluorescent surgery navigation system, in particular to an imaging device, a handheld and endoscope near-infrared imaging system and a construction method. Background technique [0002] Medical imaging technology is currently an intuitive diagnostic process for clinically detecting a variety of major diseases. Preoperative diagnosis includes nuclear magnetic resonance, CT, ultrasound, etc., which can help clinicians find the lesion and make an accurate diagnosis. At present, the equipment capable of intraoperative navigation mainly includes optical imaging technology, mainly including reflection imaging and fluorescence imaging. Fluorescence imaging is widely used in fluorescence surgical navigation systems because of its fast imaging speed, high sensitivity, and real-time imaging. [0003] Fluorescence surgical navigation systems are currently being pushed into the near-infrared region due to tissue autofluorescence and sc...
