Description

[Detailed description of the invention] The present invention relates to an endoscope device.

When diagnosing the inside of a patient's body cavity using an endoscope, conventional equipment configurations require the doctor to obtain information about the patient while looking into the image projected on the observation window provided in the operating section. It's being used.

Therefore, in cases where information from an endoscope is to be observed by multiple doctors to make a comprehensive diagnosis, the doctors involved should either take turns looking into the endoscope, or use a device as an auxiliary device. The method of making a judgment by looking at the image taken on the film surface by the camera device being developed is extremely inconvenient in cases where an immediate judgment regarding diagnosis must be made.

The present invention was made in view of the above circumstances, and
The purpose of this is to enable the information obtained from the endoscope to be displayed simultaneously on multiple display devices. The aim is to make it possible to capture images and display them on a television monitor, and also to display an ultrasound image from an ultrasound endoscopic device and an optical image on the same screen, making it possible for multiple doctors to perform comprehensive evaluations. be.

The present invention will be explained below with reference to the drawings.

FIG. 1 shows a schematic configuration of a conventionally used endoscope.

An insertion section 1 made of a flexible tube and an operation section 2 connected to the insertion section 1 are provided. The operation unit 2 includes an observation window 3 and a light guide unit 4 for illuminating the inside of the body cavity.
is attached. This light guide section 4 is connected to a light source device 5.

The observation window 3 can be viewed directly through this area with the naked eye, or a camera unit (not shown in the figure) may be attached to this area to record on film.

FIG. 2 shows an embodiment of the present invention, in which a method of directly observing information inside a body cavity through an observation window into a viewfinder and a method of displaying information captured by a solid-state observation element on a television monitor are combined. It is characterized by:

In the figure, 6 is an imaging section, and this imaging section 6
can be attached to the observation window 3. A half mirror 7 is provided inside the imaging section 6. This half mirror 7 can divide image information into two series as shown by a solid line and a dotted line at its setting position.

Therefore, screen information can be guided onto the solid-state image sensor 10 and viewfinder 9.

As a result, the output from the solid-state image sensor 10 can be displayed on the television monitor 11.

It should be noted that the same effect can of course be obtained even if the present invention uses a mirror instead of a half mirror and mechanically moves the mirror to switch the image between the viewfinder side and the solid-state imaging side in chronological order. It is.

Although only endoscopes, particularly optical endoscopes, have been described above, devices that combine ultrasonic endoscopic diagnostic devices and optical endoscopic diagnostic devices have recently been developed.
The characteristics of this device are that the optical endoscopic device is suitable for observing surface areas of organs, etc., and the ultrasonic endoscopic diagnostic device is suitable for observing internal tissue changes and lesions.

In such a device, by implementing the present invention in an optical endoscopic device, it becomes possible to display an optical image and an ultrasonic image on the screen of the same cathode ray tube, thereby facilitating image observation.

FIG. 3 shows the configuration of this embodiment. That is, information A from the ultrasonic endoscopic diagnostic device and information B from the optical endoscopic diagnostic device are alternately displayed on the screen of the monitor television 11 via the skin converter 12. The figure is a schematic diagram, and an optical endoscopic diagnostic image is shown in a, and an ultrasonic endoscopic diagnostic image is shown in b.
