Problems solved by technology

In the case of severe bleeding during ESD and other operations, hemostasis must be performed at this time, resulting in prolonged operation time
[0007] However, in order to confirm the position of blood vessels using the above-mentioned infrared endoscope device, as described above, it is necessary to perform complicated work such as intravenous injection of drugs such as ICG.
[0008] In addition, in the case of the above-mentioned infrared endoscope device, the wavelength of the illumination light is the wavelength of near-infrared light, so there is also a problem of blurring blood vessels in the image.

[0048] (Structure of endoscope device)

[0049] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0050] First, the configuration of the endoscope apparatus according to the present embodiment will be described. figure 1 It is a configuration diagram showing the configuration of the endoscope apparatus according to the present embodiment.

[0051] Such as figure 1 As shown, the endoscope device 1 of the present embodiment includes: an electronic endoscope 3, which has a CCD 2 as an imaging element, and the CCD 2 is used as a biological image information acquisition unit inserted into a body cavity to capture tissues in the body cavity or The biological image information acquisition unit; the light source device 4, which supplies illumination light to the electronic endoscope 3; and the video processor 7, which processes the imaging signal from the CCD 2 of the electronic endoscope 3, and The mirror image is displayed in th...

no. 2 approach

[0177] In the first embodiment, at least one narrow-band light is actually irradiated to the biological tissue as illumination light, and the image of the returned light is subjected to the above-mentioned emphasis processing, but in this embodiment, at least one narrow-band light is not actually irradiated to the biological tissue. For the band light, the image information of the return light of each narrow-band light is obtained by so-called spectral estimation, and the above-mentioned enhancement processing is performed on the spectral image signal of each wavelength obtained by the spectral estimation. That is, in the above-mentioned first embodiment, the first and second narrow-band lights NL1 and NL2 are generated by an illuminating device having a rotating filter or a light-emitting element such as a light-emitting diode, and the images of these returning lights are emphasized. In this embodiment, image signals corresponding to the first and second narrow-band lights NL1...

no. 3 approach

[0230]In the first embodiment, at least one narrow-band light is actually irradiated to the living tissue as illumination light, and the image of the returned light is subjected to the above-mentioned emphasis processing. In the second embodiment, the living tissue is not actually irradiated with three Narrow-band light, the image information of the return light of each narrow-band light is obtained by so-called spectral estimation, and the above-mentioned emphasis processing is performed on the spectral estimation image signals of each wavelength obtained by this spectral estimation. However, in the third embodiment, The above-mentioned emphasis processing is performed on the image signal of the return light of the actual illumination light of the narrowband light and the spectrum estimation image signal obtained by spectrum estimation.

[0231] The structure and figure 1 The illustrated endoscope apparatus 1 has the same configuration, but the configuration of the rotary fil...

Abstract

An endoscope device (1) includes: a light source device (4) that irradiates a subject with at least one illumination light having a predetermined wavelength band; The returned light from the subject is photographed; a video processor (7); and an observation monitor (5). The video processor (7) implements a process of emphasizing the first image signal (NL1) according to the difference between the first image signal (NL1) and the second image signal (NL2) to generate an emphasis-corrected image signal, the first image The signal (NL1) is an image signal having a peak wavelength of a spectral characteristic between a wavelength band including a maximum value and a wavelength band at a minimum value in terms of absorption characteristics of living tissue, and the second image signal (NL2) is the same as the second image signal (NL2). The first image signal ( NL1 ) is an image signal having a peak wavelength of a spectral characteristic in which the value of the absorption characteristic is low and the scattering characteristic of living tissue is suppressed.

Description

technical field [0001] The present invention relates to an endoscope device, and in particular to an endoscope device capable of displaying blood vessels inside a subject. Background technique [0002] Conventionally, in the medical field, various low-invasive examinations and operations have been performed using endoscopes. The surgeon inserts the endoscope into the body cavity, observes the subject captured by the imaging device installed at the front end of the endoscope insertion part, and can use the treatment instrument inserted into the treatment instrument channel to treat the lesion if necessary . Surgery using an endoscope does not require laparotomy or the like, and thus has the advantage of reducing the burden on the patient's body. [0003] The endoscope device is configured to include an endoscope, an image processing device connected to the endoscope, and an observation monitor. The lesion is imaged by an imaging element provided at the distal end of the in...
