Problems solved by technology

Although this solution can realize automatic dimming of the lighting units in the endoscope device according to the surrounding conditions, the solution needs to detect the brightness of the lighting areas of a plurality of lighting units based on the image recognition technology for the acquired image signals, so that The detection scheme is easy to receive interference, which affects the detection accuracy. At the same time, the implementation of this scheme requires a large amount of data calculation, which requires high calculation components and increases product cost.

example 1

[0035] The endoscope involved in this example is mainly composed of an insertion part, an operating part and a universal cable extending from the operating part, wherein the universal cable is connected to an external device (such as an image processor) through a connector.

[0036] An illumination unit and a camera unit are arranged at the head end of the insertion part. The illumination unit irradiates light to the body cavity of the subject, and the camera unit collects tissue images of the body cavity of the subject, and transmits the images to the image processor, and presents the images through the display after processing.

[0037] see figure 1 and figure 2 , which is a schematic structural view of the head end of the insertion part of the endoscope provided in this example.

[0038] It can be seen from the figure that the head end 100 of the insertion part in the endoscope mainly includes the head end body 110 of the insertion part and the head end cap 120 sheathed o...

example 2

[0056] see Figure 4 and Figure 5 In this example, the insertion part head 100 in the endoscope mainly includes the insertion part head body 110 and the end cap 120 sleeved on the end body 110 .

[0057] On the body 110 of the head end of the insertion part, there are provided a jaw opening 111 , an imaging assembly 112 , and a cleaning nozzle 113 . The arrangements of the nip gate 111 , the imaging assembly 112 , and the cleaning nozzle 113 are well known to those skilled in the art, and will not be repeated here.

[0058] At the same time, a head end PCB 115 is arranged at the end of the head end body 110 of the insertion part, and a corresponding lighting unit 114 is arranged on the PCB 115 . Conventional technology can be used for the head-end PCB board 115 , which will not be repeated here.

[0059] As for the lighting unit 114 in this example, multiple lighting units can be provided according to the lighting requirements of the endoscope, and the lighting unit can be...

Abstract

The invention discloses an endoscope and an illumination adjustment method. The endoscope has: an illumination unit, a distance detection unit, and an illumination control unit; Lighting: the distance detection unit detects the distance between the head end of the endoscope insertion part and the object in real time; the lighting control unit adjusts the brightness of the lighting by the lighting unit in real time according to the detection result of the distance detection unit. This solution can distribute brightness on demand, save power, avoid partial exposure, and avoid temperature accumulation; at the same time, this solution is less affected by the outside world, and has high precision and reliability.

Description

technical field [0001] The invention relates to the technology of endoscope, in particular to the technology of automatically adjusting the brightness of the light source of the endoscope. Background technique [0002] Endoscopes are widely used in the field of medical diagnosis. The endoscope is configured to have an insertion part, an operation part, and a universal cable extending from the operation part, and the universal cable is connected to an external device through a connector. Since the endoscope needs to be inserted into a dark space for diagnosis and treatment, it is necessary to illuminate the observation field. The quality of illumination on the observation field is related to the image quality, overexposure or too dark are not conducive to imaging. [0003] Existing light sources cannot be locally dimmed, so it is easy to cause some areas in the observation field to be overexposed while others are too dark, resulting in uneven brightness and darkness of the ...
