Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable endoscope apparatus.
[0002]
[Prior art]
In recent years, endoscopes are widely used in the medical field and the industrial field. In this endoscope, since a diagnosis or inspection target is inside a living body, a plant, or the like, a light source that illuminates the observation target is necessary. Therefore, in a general endoscope apparatus, a light source device is prepared as an external device of the endoscope, illumination light emitted from the light source device is supplied to a light guide provided in the endoscope, and this illumination light is The light is emitted from the illumination window at the distal end of the insertion portion of the endoscope to illuminate the endoscopic examination site. Then, an optical image is formed at the imaging position of the objective optical system attached to the observation window adjacent to the illumination window.
[0003]
Here, when the endoscope is an optical type, the end face of the image guide is arranged at the image forming position, and the formed image is transmitted to the proximal end side of the insertion portion by the image guide, and the user receives the eyepiece portion. Through the eyepiece optical system, it is possible to perform an enlarged observation of the endoscopic observation site. For this reason, the power source of the light source device can be a battery such as a dry battery or a rechargeable battery, so that an endoscope device excellent in portability can be configured. This makes it possible to use in a place where it is difficult to carry a large light source device or a place where a commercial power source cannot be secured, and an excellent effect is exhibited particularly in an emergency.
[0004]
[Problems to be solved by the invention]
However, when the endoscope is an electronic type, an image pickup device such as a charge coupled device (CCD) is disposed at the image formation position to photoelectrically convert the optical image into an image signal. The image signal output from the image sensor is processed by a video processing device to generate a video signal, and the video signal is output to a monitor device to display an image of an endoscopic observation site on the screen. Make observations. That is, in the case of performing an inspection with an electronic endoscope, a video processing device and a monitor device are required in addition to the combination of the endoscope and the light source device, which is a configuration of the optical endoscope device. Therefore, it is difficult to configure a portable endoscope apparatus.
[0005]
The present invention has been made in view of the above circumstances. The light source device, the video processing device, and the monitor are powered by a battery such as a dry battery or a rechargeable battery, and the portable endoscope has excellent portability and workability. It aims to provide a mirror device.
[0006]
[Means for Solving the Problems]
The portable endoscope apparatus according to the present invention supplies an endoscope having an image pickup element built in the distal end portion of the insertion portion, an image processing section that generates a video signal from an image signal output from the image pickup element, and a power source. An apparatus main body provided with a battery, a belt provided in the apparatus main body for wearing the apparatus main body, and a display device that receives the video signal output from the image processing unit and displays an endoscopic image A portable endoscope apparatus comprising a display device arrangement member that is fixed and includes a sliding portion that slidably arranges the display device with respect to the device main body. There,
The display device arrangement member includes a vertical axis rotation unit that rotates the display surface of the display device around a vertical axis direction and a horizontal axis direction rotation unit that rotates the display device around a horizontal axis direction. A rotating member is provided .
[0007]
The display device arrangement member includes a sliding portion that moves the display device forward and backward in the longitudinal direction of the device main body, and a vertical axis direction rotation portion that rotates the direction of the display surface of the display device in the vertical axis direction. And a horizontal axis direction rotating part that rotates in the horizontal axis direction.
[0008]
According to this configuration, immediately after bringing the storage case to the observation place, the endoscope and the apparatus main body are taken out from the storage case, so that the endoscope image is displayed on the display device arranged in the apparatus main body. Endoscopic observation can be performed.
[0009]
Then, by using the sliding portion, the vertical axis direction rotating portion, and the horizontal axis direction rotating portion that the display device arranging member has, the display surface of the display device is changed to a desired position, and in the best observation state. Can be observed.
