ENDOSCOPE CAPABLE OF DISPLAYING A SCALE FOR DETERMINATION OF THE SIZE OF THE TARGET
First Claim
1. An endoscope capable of displaying a scale for determination of the image size of a target, comprising:
- an endoscope body comprising a display device and a set of buttons;
a display control circuit electrically coupled with said display device and said buttons and adapted for receiving an image signal and displaying the received image signal on said display device and being controllable by the user by means of said buttons;
a flexible tube member having one end thereof connected to said endoscope body;
an image pickup module installed in the other end of said flexible tube member and electrically connected to said display control circuit by an electric wire in said flexible tube member and adapted for picking up the image of a target and transmitting the image signal thus obtained to said display control circuit;
wherein said flexible tube member is provided with a stop pin, said stop pin having a proximal end thereof connected to the composite of said flexible tube member and said image pickup module and a distal end thereof extending out of the composite of said flexible tube member and said image pickup module to a predetermined length;
said display control circuit comprises a scale display procedure for displaying a scale on said display device, said scale having sufficient accuracy for determining the size, area or angle of said target only when the distal end of said stop pin is stopped against said target.

Abstract
An endoscope includes an endoscope body carrying a display device and buttons, a display control circuit, a flexible tube member, an image pickup module, and a stop pin, which has a proximal end thereof connected to the composite of the flexible tube member and the image pickup module and a distal end thereof extending out of the composite to a predetermined length. Further, the display control circuit includes a scale display procedure, which is adapted for displaying a scale on the display device and has sufficient accuracy for determining the size, area or angle of the target only when the distal end of the stop pin is stopped against the target. Thus, the stop pin can be used to establish a distance between the image pickup module and the target, enabling the scale to be used for determination of the size, area or angle of the target being displayed on the display device.
