Abstract

PURPOSE:To automatically perform a process suitable for a mounted adapter by identifying the type of an adapter and whether an adapter is mounted and performing a process suitable for the mounted adapter in response to the identified output. CONSTITUTION:The energized condition of an adapter identifying pin 35 loaded on a leading edge part varies depending on the type of the adapter mounted on the leading edge part. The variety of the energized condition is identified by an identifying circuit 109 in a control device 42, and the type of the mounted adapter is identified. When a lateral sight adapter 80 is mounted an image is inverted by changing the writing or reading operation of frame memories 105a and 105b, and the image displayed on a monitor device goes to a normal image. Thus, a process suitable for the mounted adapter is automatically performed without manually switching a switch, etc., depending on a mounted adapter, and operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to an endoscope Vt position in which an adapter can be detachably attached to the distal end of the insertion section.

[Prior art and problems to be solved by the invention] In recent years, by inserting an elongated insertion part into a body cavity, organs in the body cavity can be observed, and if necessary, a treatment instrument can be inserted into a channel. Endoscopes that can perform various therapeutic procedures using treatment tools are widely used.

Furthermore, various electronic endoscopes using solid-state m-image elements such as charge-coupled devices (CODs) as imaging means have been proposed.

By the way, some endoscopes have various optical adapters that can be detachably attached to the distal end of the insertion section, and the angle of view, direction of view, etc. can be changed using these adapters. One of these adapters is a side viewing adapter that enables side viewing by being attached to the distal end of a direct viewing endoscope.

However, when a side-viewing adapter with a reflective member that reflects the image only once is attached to the tip of a direct-viewing electronic endoscope, the subject image displayed on the display device is reversed only vertically or horizontally. The displayed image (real image) will be displayed. Incidentally, JP-A-58-12638 has a description that an erect image can be obtained on the display device when the side viewing adapter is attached, but there is no more specific description. Generally, it is possible to install a means for reversing an image within the video signal processing device, and to instruct this means to reverse the image using a switch provided in the video signal processing device. In addition to being cumbersome to change the switch, there are times when you forget to change the switch,
There is a risk of switching by mistake.

Note that, depending on the type of the adapter, there may be cases where it is necessary to form or change a mask on the display screen, change the aperture, etc., but such cases also have the same problems as described above.

Furthermore, Japanese Patent Application Laid-Open No. 53-43989 discloses a technique in which a tip adapter having a built-in solid-state image sensor can be connected to the tip of an insertion section in a replaceable manner.
According to this conventional example, it is possible to obtain an appropriate image for each adapter without distinguishing the type of tip adapter, but all objective optical systems and solid objects 11 are included in the tip adapter.
Since the i1(l element is built-in), there is a problem that the tip adapter becomes bulky and expensive.

In addition, the connection between the tip adapter and the endoscope tip is performed by a method such as screwing, but if the threaded portion of the two becomes loose and the operator does not notice this, the tip adapter may become loose. There is a problem that it may fall off.

To deal with this, conventionally, for example,
Publication No. 43 and Japanese Patent Application No. 62-2 filed earlier by the applicant.
As shown in Memorandum No. 90299, if an abnormality occurs in the observed image such as a part of the field of view being vignetted or the entire field of view becoming whitish, it is notified that the tip adapter will fall off from the end of the endoscope. It was used as a means.

However, even if an abnormality occurs in the observed image, it does not mean that the image cannot be seen at all, so there is a risk that the user may continue to use the tip adapter without noticing that it is about to fall off. Thus, conventionally, it has not been possible to reliably notify the operator that the tip adapter is about to fall off.

[Object of the invention] The present invention has been made in view of the above circumstances, and
It is an object of the present invention to provide an endoscope device that can automatically perform processing suitable for a compatible adapter.

A further object of the present invention is to provide an endoscope device that can reliably notify the operator that the adapter is about to fall off.

[Means and effects for solving the problem] Internal view of the present invention
11 The device includes an identification means for identifying the type of adapter attached to the distal end of the insertion portion of the endoscope body or whether an adapter is attached to the distal end, and an identification device according to the identification output of the identification means. The system is equipped with a control means that performs processing appropriate for the attached adapter, and is configured to identify the type of adapter or whether or not an adapter is attached, and automatically perform processing appropriate for that adapter. This is what I did.

In addition, the endoscope Vt stroke according to the present invention includes a discriminating means for discriminating whether or not the adapter is installed at a proper position at the distal end of the insertion section, and a discriminating means for discriminating whether the adapter is disposed at a proper position in accordance with the discriminating output of the discriminating means. If the adapter is not installed in the correct position, a notification means is installed to notify the operator that the adapter is not installed in the correct position. This is what I did.

This external attachment of the eyepiece of the fiberscope can also be applied to an endoscope device equipped with a television camera.

In addition, if the endoscope is a fiberscope, an LED, etc. is installed near the eyepiece in the eyepiece, and if the adapter is about to fall, this LED will emit light, and this will cause observation within the field of view. If possible, it may also be used as a warning display.

Further, the warning is not limited to a display, and may be a sound such as a buzzer.

Also, the second. In the third embodiment, an example of the direct viewing type tip optical adapter 50 was shown as the adapter, but it goes without saying that a side viewing adapter 80 or the like may also be used.
