Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0023] Such as figure 1 , 2 As shown, the endoscope 1 of this embodiment has an elongated insertion portion. For example, a cleaning nozzle 3 , an observation window 4 a , and an opening 6 b of the treatment instrument insertion hole 2 a are provided on the front end surface 6 a of the endoscope 1 .

[0024] In addition, reference numeral 5 denotes a light-emitting element, such as a light-emitting diode, which constitutes an illumination optical unit 20 to be described later.

[0025] Such as figure 2 As shown, the insertion part 2 is constituted by successively providing a front end part 6 , a bending part 7 , and a tubular flexible flexible tube part (not shown) sequentially from the front end side. The bending portion 7 has a front end bending piece 7 f on the front end side. The bending piece 7a and a plurality of not-shown bending pieces are connected to the...

Abstract

An endoscope includes: a distal end rigid member made of a metal and provided on a distal end side of a bending portion, an observation optical portion being fixedly provided in the distal end rigid member; a distal end cover formed of an insulating resin member and fixed to the distal end rigid member in an integrated manner, the distal end cover including a transparent illuminating window portion included in an illumination optical portion and a light-emitting device installing hole; a light-emitting device arranged in the light-emitting device installing hole, the light-emitting device including a light-emitting portion that faces the illuminating window portion included in the distal end cover and is fixed at a predetermined position, and a conductive portion positioned on the illuminating window portion side relative to an opening of the light-emitting device installing hole, the conductive portion being opposed to the opening of the light-emitting device installing hole; a substrate having thermal conductance and combining as a heat dissipating member, the substrate being connected to the conductive portion of the light-emitting device, and a power supply cable that supplies power being connected to the substrate; and a heat dissipation member having a plate shape and thermal conductance, an end side of the heat dissipation member being connected to the substrate and another end side of the heat dissipation member projecting relative to the substrate to dissipate heat conducted to the substrate.

Description

technical field [0001] The present invention relates to an endoscope in which a light-emitting element is disposed as an illumination optical system at a distal end portion of an insertion portion. Background technique [0002] Endoscopes are widely used in the medical and industrial fields. In an endoscope, an object of diagnosis or observation is the inside of a living body, a mechanical device, or the like. Therefore, when performing endoscopic observation, a light source for illuminating the observation object is required. [0003] A general endoscope device includes an endoscope and a light source device as an external device of the endoscope. The illumination light emitted by the light source device is supplied to a light guide provided in the endoscope. The supplied illumination light is transmitted by the light guide, and is emitted from an illumination window arranged at the front end of the insertion portion of the endoscope to illuminate the observation object....
