Endoscope
First Claim
1. An endoscope comprising:
- a distal-end adapter including;
light emitting devices, the light emitting devices being arranged in a first surface of a substrate;
an illumination optical system;
the substrate for the light emitting devices including a first electric connecting unit for the light emitting devices, the first electric connecting unit being arranged in a second surface of the substrate;
a support member for supporting the substrate;
a first heat-conducting member through which heat generated by the light emitting devices is conducted; and
an objective optical system constituting an observation optical system; and
an insertion unit having a distal end portion from which the distal-end adapter is detachable, the distal end portion including;
an image pickup device constituting the observation optical system;
a second electric connecting unit which is electrically connected to the first electric connecting unit in the substrate;
a second heat-conducting member through which the heat transferred through the first heat-conducting member is further conducted; and
a heat-radiating member for radiating the heat conducted through the second heat-conducting member from the distal end portion in the direction toward a proximal end of the endoscope, the heat-radiating member including a bundle member formed by tying wires in a bundle with a binding member, each wire having a diameter of 0.1 mm or smaller.

Abstract
An endoscope is provided capable of performing excellent observation for a long time by preventing decrease in light amount and generation of image noise caused by heat generated by an LED illumination even in a case where a distal-end adapter configured of the LED illumination is arranged at the distal end portion of the insertion unit. One end portion of a heat-radiating member configured of a plurality of elongated wires is arranged in the vicinity of a light emitting device, on the other hand, the other end portion of the heat-radiating member is arranged at a predetermined position on a proximal end side of an insertion unit, and a binding member for binding the wires of the heat-radiating member is provided on a side in the vicinity of the light emitting device of the heat-radiating member.
