Abstract

An endoscope system includes an endoscope, light source unit and photographic attachment are connected to a centralized supervision-control device which collectively supervises and controls the overall operating condition of the endoscope, light source unit and photographic attachment.

Claims

1. An endoscope system comprising:

an endoscope including a light guide;

an image guide;

an eyepiece section; and

an endoscope connection signal generator for generating an endoscope connection signal;

a light source unit including a light source for conducting light to the light guide of the endoscope; and

a light source unit connection signal generator for generating a light source unit connection signal;

a photographic attachment including means for connection to the eyepiece section of the endoscope to photograph a coeliac cavity; and

a photographic attachment connection signal generator for generating a photographic attachment connection signal;

a centralized supervision-control unit for supervising and controlling the operation and interaction of the endoscope, light source unit and photographic attachment with respect to each other; and

signal transmission lines for electrically connecting the centralized supervision-control unit to the endoscope, to the light source and to the photographic attachment to thereby transmit the respective connection signals to the centralized supervision-control unit and to perform data-transmission between the centralized supervision-control unit and the endoscope, light source unit and photographic attachment, said centralized supervision-control unit supervising and controlling in response to the connection signals the operation and interaction of the endoscope, light source and photographic attachment.

2. The endoscope system according to claim 1, wherein the centralized supervision-control unit is located in the light source unit.

3. The endoscope system according to claim 1, wherein the light source unit further includes a data buffer, through which a bidirectional data transmission is carried out between the light source unit and the centralized supervision-control unit.

4. The endoscope system according to claim 1, wherein the endoscope includes a suction pump and suction pump controller, the signal transmission line between the endoscope and the centralized supervision-control device being coupled to the suction pump controller;

and the suction pump is selectively actuated by the suction pump controller and centralized supervision-control unit.

5. The endoscope system according to any one of claims 1, 2, 3 or 4, wherein the centralized supervision-control unit includes display means for indicating the overall operating condition of the endoscope, light source unit and photographic attachment.

6. The endoscope system according to claim 4, wherein the endoscope includes a pressure sensor;

and the centralized supervision-control unit includes means for controlling the operation of the suction pump in accordance with the magnitude of pressure detected by the pressure sensor.

7. The endoscope system according to claim 5, wherein the light source unit includes a light fault detector for detecting a fault in a light source;

and the centralized supervision-control unit includes means for causing an indication "light fault" to be made by the display means in response to an output from the light fault detector.
