Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope connector device in which a signal connector connected to a solid-state image pickup device of an endoscope is removably inserted into a connector receiver of a signal processing device.

[0002]

2. Description of the Related Art In a connector device for an endoscope of this type, a single-color index is provided on each of the signal connector of the endoscope and the connector receiver of the signal processing device, and if the colors of the indices are the same, they are connected. As a matter of fact, the signal connector is connected to the connector receiver.

[0003]

With the improvement of the solid-state image pickup device provided in the endoscope, the signal processing device side is also improved. This causes so-called upward compatibility between the endoscope and the signal processing device.

FIG. 3 shows the upward compatibility, and before and after the improvement, it is possible to connect the endoscopes before and after the improvement to the signal processing apparatus after the improvement. Do not connect the mirror to the original signal processor.

However, as in the prior art, it is not possible to express the above-described upward compatibility only by providing a single-color index to each of the signal connector on the endoscope side and the connector receiver on the signal processing device side. In some cases, the improved endoscope was connected to the signal processing device before the improvement to cause a circuit diagnosis or a false diagnosis due to an abnormal image.

Therefore, an object of the present invention is to provide a connector device for an endoscope, which can ensure the required upward compatibility as the devices are improved.

[0007]

To achieve the above object, the connector device for an endoscope according to the present invention is provided with a solid-state image pickup device for converting an observation image into an electric signal and transmitting the electric signal. , A signal connector connected to the solid-state image pickup device is removably inserted into a connector receiver of a signal processing device, and a signal line connection is made between the solid-state image pickup device and a circuit in the signal processing device. In the connector device of the endoscope, an indicator of the same color is provided to indicate that the endoscope and the signal processing device can be connected, and after the improvement with the improvement of the solid-state image sensor of the endoscope. While changing the color of the index of the endoscope to a color different from the color before the improvement, with the improvement of the signal processing device according to the improvement of the solid-state imaging device, in addition to the color index before the improvement Signal processing after improving the index of the same color as the index of the endoscope Characterized in that added to the apparatus.

Embodiments will be described with reference to the drawings. Figure 2
A signal connector 11 of an endoscope having a solid-state image pickup device (not shown) for converting an observation image into an electric signal and transmitting the electric signal, a drive signal output circuit for driving the solid-state image pickup device, and a solid-state image pickup device. 1 shows a video processor (signal processing device) 20 having a built-in circuit for processing an image signal sent from an element. The video processor 20 is also provided with a light source lamp for illumination and the like.

The signal connector 11 is provided with a large number of contact pins (not shown) connected to the solid-state image pickup device. Further, a light guide connector 12 to which an incident end of a light guide fiber bundle for illumination is attached is provided in parallel with the signal connector 11.

The video processor 20 is provided with a connector receiver 21 and a light guide connector receiver 22 side by side, to which the signal connector 11 and the light guide connector 12 of the endoscope are removably connected.

Both connectors 11 and 12 on the endoscope side
Both connector receivers 21 and 22 on the video processor 20 side
When the solid-state image sensor is electrically connected to the drive signal generation circuit and the signal processing circuit, the light from the light source lamp is supplied to the illumination light guide fiber bundle.

The signal connector 11 on the endoscope side and the connector receiver 21 on the video processor 20 side configured as described above.
And are provided with indicators 101 and 201, respectively. FIG. 1 shows how to attach the indexes 101 and 201 described above.

In this embodiment, in the first model, both the indicator 101 on the signal connector 11-1 side and the indicator 201 on the connector receiver 21-1 side are provided with a red single color indicator.

When the solid-state image pickup device of the endoscope is improved, the signal connector 11-2 of the improved endoscope is provided with a yellow single color indicator 102 different from that before the improvement. On the other hand, in the connector receiver 21-2 on the video processor 20 side having the circuit improved with the improvement of the solid-state imaging device, in addition to the red indicator 201 before the improvement, the indicator of the signal connector 11-2 after the improvement The same yellow index 202 as 102 is attached.

Further, when the solid-state image pickup device of the endoscope is improved once again, the signal connector 11-3 of the improved endoscope is improved.
Is attached with a blue monochromatic index 103 different from that before the improvement.

Then, in the connector receiver 21-3 on the video processor 20 side, in addition to the red index 201 and the yellow index 202 before the improvement, the signal connector 11 after the improvement
The same blue index 203 as the index 103 of −3 is attached.

The color-coded indicators indicate that the same color is connectable. Therefore, looking at the color of each index of the signal connector 11 of the endoscope and the connector receiver 21 of the video processor 20, if the connector receiver 21 side includes the index of the same color as the index of the signal connector 11, the signal connector 11 and the connector receiver 21 are connected,
Do not connect them unless you have indicators of the same color.
As a result, upward compatibility is achieved in which only the signal connector 11 and the connector receiver 21 having the relationship shown by the arrow in FIG. 1 are connected.

The present invention is not limited to the above embodiment, but the shape and color of the index can be arbitrarily selected, and the position where the index is provided is limited to the signal connector 11 and the connector receiver 21. Instead, it may be any part of the endoscope and video processor.

[0019]

According to the connector device for an endoscope of the present invention, it is possible to see the color of an index and appropriately connect the endoscope and the signal processing device in accordance with the color, which is in the hands of the user. Upward compatibility can be obtained without any modification to the endoscope and signal processing device that have been lost. Moreover, it is easy by making a slight additional work on the parts used in the device before improvement. And it can be realized at low cost.
