Abstract

An electronic endoscope (1) is provided with the following: a plurality of metal cylinder members (51, 55, 59, 63) that are connected by electrical conduction so as to electromagnetically shield an internal space formed in an insertion part (2); a treatment tool channel (48) in which the center (O1) is disposed in any one quadrant of an orthogonal coordinate system with the origin thereof being the center (O) of the insertion part (2); and a plurality of small signal cables (31, 32, 33) that extend from an image pickup unit (30) and that have disposed therein, within at least a curved section (7), centers (O2, O3, O4) in quadrants that are different from the above any one quadrant and that are divided from that one quadrant at one axis (Y) of an orthogonal coordinate system which follows the curving vertical direction of the curved section (7). By being provided with the foregoing, the electronic endoscope can secure electromagnetic compatibility (EMC) and make the diameter of the insertion part smaller by efficiently disposing the plurality of cables so that the cables do not buckle within the curved part.

Description

technical field

[0001] The present invention relates to an electronic endoscope provided with an imaging device at the distal end of an insertion portion. Background technique

[0002] Conventionally, there is an electronic endoscope having an imaging device for forming an observation image of a subject focused by an objective optical system provided at a distal end of an insertion part and camera.

[0003] In such a conventional electronic endoscope, for example, as disclosed in JP-A-2006-55531, a signal cable harness as an imaging cable for transmitting power and drive signals to an imaging device passes through the main body, the composite body, and the insertion portion from the insertion portion. Cables and the like are arranged to an endoscope connector connected to external devices such as a video processor.

[0004] A plurality of signal system cables and power supply cables provided in such conventional electronic endoscopes are arranged as one signal cable bundle...
