Referring to fig. 10, an embodiment of the endoscopic imaging system 1000 is provided, and the endoscopic imaging system 1000 includes the endoscopic light source device 10, the light guide bundle 20, the hard tube endoscope 30, the optical bayonet 40, the camera 50, the camera connection line 81, the host 60, the display 70, and the video connection line 82 in the above embodiments.
The host 60 is connected to the camera 50 through a camera connection line 81, and an image signal obtained by the camera 50 is transmitted to the host 60 through the camera connection line 81 for processing.
In some embodiments, the camera connection cord 81 may be an optical communication cable, such as an optical fiber, and the camera connection cord 81 may also be an electrical communication cable, such as an electrical wire.
The camera 50 converts an image signal (electrical signal) into an optical signal, and the optical signal is transmitted to the host 60 through the camera connection line 81, and the host 60 converts the optical signal into an electrical signal. Host 60 is connected to display 70 via video connection 82 for sending video signals to display 70 for display.
The endoscope light source device 10 is used to provide an illumination light source including laser light illumination and white light illumination to the site to be observed 100.
In the present embodiment, the endoscope light source device 10 includes a visible light source and a laser light source corresponding to a fluorescent reagent. The visible light source is an LED light source. In one embodiment, the visible light source can provide a plurality of monochromatic lights in different wavelength ranges, such as blue light, green light, red light, and the like. In other embodiments, the visible light source may also provide a combination of the plurality of monochromatic lights, or a broad spectrum white light source. The wavelength range of the monochromatic light is approximately 400nm to 700 nm. The laser light source is used for generating laser light. The laser light is, for example, Near Infrared (NIR). The peak wavelength of the laser takes at least any 1 value in the range of 780nm or 808 nm.
Since the endoscope light source device 10 can simultaneously provide continuous white light and laser light corresponding to the fluorescent reagent to the portion to be observed, the collection efficiency of the visible light image signal and the fluorescent image signal reflected by the portion to be observed 100 by the camera 50 is improved.
Wherein a contrast agent, such as Indocyanine Green (ICG), is introduced intravenously or subcutaneously in the site 100 to be observed prior to imaging using the endoscopic camera system 1000, in order to image tissue structures and functions (e.g., blood/lymph/bile in vessels) that are not readily visible using standard visible light imaging techniques. Sites to be observed 100 include, but are not limited to, the blood circulation system, the lymphatic system, and tumor tissue. ICG is commonly known as indocyanine green, a diagnostic green needle, indocyanine green, which is a commonly used contrast agent in clinical diagnosis of cardiovascular system diseases at present, and is widely used in choroidal and retinal vessel imaging. The contrast agent in the region 100 to be observed may generate fluorescence when it absorbs the laser light corresponding to the fluorescent agent generated by the laser light source.
In this embodiment, since the endoscope light source device 10 is provided with the detection device 5, the detection device 5 can generate the trigger signal when the light beam is not inserted into the exit end of the optical module, and the controller turns off the laser light source and the white light source according to the trigger signal, or the controller 6 controls the laser light source 2 to stop emitting the laser light and the white light source 3 to reduce the brightness of emitting the white light, so that the white light and the laser light can be prevented from being emitted from the inside of the light source to cause damage to people, and the energy consumption can be saved.
The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
