Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
199 words
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.

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.
Claim 3
Dependent Claim
19 words
The endoscope system according to claim 1, wherein the centralized supervision-control unit is located in the light source unit.
Claim 4
Dependent Claim
36 words
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.
Claim 5
Dependent Claim
53 words
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.
Claim 6
Dependent Claim
37 words
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.
Claim 7
Dependent Claim
41 words
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.
Claim 8
Dependent Claim
55 words
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.
