Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system rack for an endoscopic system.

An endoscope system consisting of the endoscope body, light source device, air/water supply, suction device, data generation device, etc. requires a system rack to house these system devices. As disclosed in Patent Publication No. 2749703 or German Utility Model Publication No. 6933990, the system rack itself did not have any other functions because a space suitable for storing each device was simply provided. For example, when it is necessary to connect devices with signal transmission paths, when each device is stored in a system rack, the signal line can be installed at the back of the system rack or in a narrow space between devices in the system rack. It is necessary to connect the devices together by running the In such wiring, the wiring work is not easy, and there is a risk of erroneous wiring or poor wiring, which may make it difficult to operate the endoscope system normally.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a system rack for an endoscope system that can easily and reliably connect devices of the endoscope system.

The control unit 38 is connected to a control unit 38 as shown in FIG.

A control unit 38 in the light source device 6 includes a microcomputer 40, a system controller 42, and a bus driver 44, and is connected to input/output ports 52 and 54 via a data bus 46, an address bus 48, and a control bus 50, respectively. There is. One input/output port 52 is connected to a control circuit 56 for controlling the light source and camera, for example, controlling the light emission time of the light source or inputting data to the film loaded in the camera.
6 is connected to an endoscope 14 and an endoscope camera 12. The other input/output port 54 is connected to the buffer 5
8, 60, and 62 to the second connector 24.

From the system rack, there is a commercial power outlet 6.
A power cord 66 for connecting to the system rack 2 extends out, and this power cord 66 is connected to a terminal block 68 fixed to the bottom surface of the system rack 2 in the spare space. This terminal block 68 is connected to a DC power supply circuit 70 for AC/DC conversion, which is also provided on the bottom of the system rack in the spare space, and is connected to the AC power supply circuit 70 via a first AC power supply path 72 extending inside the spare space. 2
It is connected to a receptacle 74 provided on the partition plate 4 of. This receptacle 74 is connected to a plug 78 provided on a power cord 76 extending from the light source device 6 . Further, the terminal block 68 is connected to the air supply, water supply, and suction device 8 via a second AC power supply path 80 extending within the preliminary space.
The DC power supply circuit 70 is connected to the first and third connectors 22 and 28, respectively, through first and second DC power supply paths 82 and 84 extending within the system rack side wall and the first partition plate 3. , the data generator 10, and the external computer 18, respectively. Furthermore, the system rack 2 is provided with ground terminals 86 and 88 that are connected to the ground terminals of each device, and are connected to an external ground terminal 94 via a ground wire 92 extending from the ground terminal 90 of the system rack 2. Common grounding can be achieved by this.

According to the system rack 2 for an endoscope system of the present invention as described above, each device 6, 8, 10 is installed in the system rack 2.
By connecting the devices 8, 10 to the connectors 24, 28, 32 provided in the system rack 2, the devices 6, 8, 10 can be connected to each other through signal transmission paths 30, 34,
Connected at 36. At the same time, each device 6, 8,
By connecting the ground terminals 10 to the ground terminals 86, 88 of the system rack 2 and the ground wire 92 to the external ground terminal 94, all devices 6, 8, 10 are grounded and leakage current is grounded. It can be released to the terminal 94. Furthermore, connector 2

By attaching the external computer 18 to the connector 22, the external computer 18 can be connected to the control unit 38 of the light source device 6.

After each device of the endoscope system is thus housed in the system rack 2, the endoscope system is operated as follows. For example, when taking a photo, the light source device 6 is connected to the endoscope 1.
The reflected light containing image information is detected by a photoelectric element via the image guide. This detected signal is supplied to the control circuit 56 and given to the microcomputer 40 via the input/output port 52 to determine the exposure time. The determined exposure time is sent from the microcomputer 40 to the input/output port 52 as a light emission stop signal.
The light is supplied to the control circuit 56 via the light source device 6, and the light emission of the light source in the light source device 6 is stopped. As a result, the image transmitted through the image guide is recorded on the film of the endoscope camera 12 with proper exposure.

If data, such as the date and time of photography or the patient's name, is to be imprinted on the film at the same time as the photograph is taken, the necessary data is entered in advance using the data generator 10, and instructions are given to the microcomputer 40 via the input/output port 54. . Based on this instruction, the microcomputer 40 gives necessary instructions to the endoscopic camera 12 via the input/output port 52, and causes the endoscope camera 12 to record data on the film.

In addition, when operating the air/water supply and suction device 8 using the operating section of the endoscope 14, the command signal generated at the operating section is transmitted to the control circuit 56 and the input/output port 5.
2 to the microcomputer 40. The microcomputer 40 decodes this and provides necessary control signals to the air/water supply and suction device 8 via the input/output port 54 to operate the device 8.

Further, when a predetermined sequence is stored in the external computer 18 and the endoscope system is operated according to this sequence, necessary data is sequentially transmitted from the external computer 18 to the microcomputer 40 via the input/output port 54. given to. Therefore, the microcomputer 40
Each device 6, 8, 1 sequentially based on the given data
2 will be controlled.

In the above embodiment, the control unit 38 is provided in the light source device 6;
8 may be provided separately and housed in the system rack 2 in place of the data generator 10, as shown in FIG. 1, with or without adding the functions of the data generator 10. In addition, the signal transmission paths provided in the system rack 2 are not only for the devices shown in the above-mentioned embodiments, but also signal transmission paths for attached devices that are not necessarily required are provided to increase versatility. It is clear that one signal transmission path may be designed in advance so that it can be used in various devices or devices.
