Description

【０００１】
【発明の属する技術分野】
この発明は、照明光源として発光ダイオードが挿入部の先端に内蔵された内視鏡の先端部に関する。
【０００２】
【従来の技術】
内視鏡においては、挿入部外に配置された光源ランプから放射された光を、挿入部内に挿通されたライトガイドファイババンドルによって伝達する構成が一般的であるが、照明光源として挿入部の先端に発光ダイオードを内蔵させて、装置の簡素化を図ったものがある。
【０００３】
【発明が解決しようとする課題】
しかし、発光ダイオードが内視鏡の挿入部内という狭くて放熱性のよくない環境下で連続点灯されると、発光ダイオードの温度が上昇し、その結果として、発光ダイオードの発光効率が低下して暗くなったり寿命が著しく短くなってしまう問題が生じる。
【０００４】
そこで、例えば挿入部外から冷却用の空気又は水等を循環させて発光ダイオードを冷却することが考えられるが、発光ダイオードを冷却するための配管を挿入部内に挿通配置すると、挿入部の外径サイズが太くなって、内視鏡検査を受ける人に与える苦痛を増大させてしまう。
【０００５】
そこで本発明は、照明光源として挿入部の先端に内蔵された発光ダイオードを、内視鏡の挿入部を太くすることなく効果的に冷却することができる内視鏡の先端部を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記の目的を達成するため、本発明の内視鏡の先端部は、挿入部の先端に設けられた照明窓内に発光ダイオードを配置して、発光ダイオードから放射される光により被写体を照明するようにした内視鏡の先端部において、発光ダイオードを囲んで熱伝導性のよい高伝熱部材を配置すると共に、挿入部の先端に設けられた観察窓の表面に向かって吹き付けられる流体が通過する流体通過路を、高伝熱部材に形成したものである。
【０００７】
なお、高伝熱部材が挿入部の先端部分の外表面に露出しないように、挿入部の先端部分の外表面を熱伝導性の悪い部材によって形成すれば、高伝熱部材の温度上昇に起因する体内粘膜面の火傷等が発生しない。
【０００８】
【発明の実施の形態】
図面を参照して本発明の実施例を説明する。
図２は内視鏡の全体構成を示しており、可撓管状の挿入部１の先端に対物光学系等が内蔵されていて、観察対象となる被写体１００に対して照明光が照射される。
【０００９】
挿入部１の基端に連結された操作部３には、挿入部１の先端に内蔵された後述する照明用の発光ダイオードに駆動電力を供給するための電池パック６が、着脱自在に取り付けられている。
【００１０】
４及び５は、送気送水及び吸引の各操作を行うための操作弁である。また、７及び８は、外部に設けられた吸引装置と送気送水装置であり、各々に接続されたチューブが操作部３に対して着脱自在に接続されている。
【００１１】
図３は挿入部１の先端面を示しており、電気絶縁性であって熱伝導性の悪いプラスチック材からなる先端部本体１０の端面に、観察窓１１、照明窓１２、送気ノズル１３、送水ノズル１４及び処置具突出口１５が配置されている。
【００１２】
観察窓１１の内部には対物光学系（図示せず）が配置されており、対物光学系により結像された被写体１００の像が、イメージガイドファイババンドル等によって伝送されるようになっている。
【００１３】
送水ノズル１４と送気ノズル１３は、観察窓１１の表面に開口を向けて先端部本体１０の端面から突設されており、観察窓１１の表面に向けて水と空気を噴出させて観察窓１１の表面の汚れを洗浄することができる。
【００１４】
図１は、送水ノズル１４と照明窓１２の各々の中心を通る断面における挿入部１の先端部分の側面断面図であり、照明窓１２に装着された凹レンズの内側に白色光を発する発光ダイオード２０が配置され、その後方の挿入部１内に電線２１が引き通されている。
【００１５】
発光ダイオード２０は、先端部本体１０に直接取り付けられているのではなく、IV−IV断面を図示する図４に示されるように、例えば銅、アルミニウム、又はそれらの合金材等のような熱伝導性のよい金属材料からなる高伝熱部材１７に、発光部の外周面が囲まれる状態に支持されている。図４において、２３はイメージガイドファイババンドル、２４は送気通路孔、２５は処置具挿通チャンネルである。
【００１６】
高伝熱部材１７は、先端部本体１０に形成された孔にピッタリと嵌め込まれて固着されており、挿入部１の先端部分の外表面に高伝熱部材１７が露出しないよう、高伝熱部材１７の外表面側に位置する部分は全て先端部本体１０によって形成されている。
【００１７】
そして、送気送水装置８から送られてくる水が通る送水チューブ１９の先端が高伝熱部材１７に後方から接続固着されていて、この送水チューブ１９と送水ノズル１４との間を接続する送水通路孔１８（流体通過路）が高伝熱部材１７に穿設されている。
【００１８】
このように構成された実施例の内視鏡の先端部においては、発光ダイオード２０から放射される照明光が照明窓１２を通って被写体１００に照射される。そして、観察窓１１の表面を洗浄する必要に応じて、操作部３に配置された操作弁４で送水操作を行うことにより、外部の送気送水装置８から送られてきた水が送水通路孔１８を通って送水ノズル１４から観察窓１１の表面に向けて噴出される。
【００１９】
したがって、点灯状態にある発光ダイオード２０から発生する熱が、高伝熱部材１７を通って送水通路孔１８内を通過する水に伝導されて外部へ排出され、その結果、発光ダイオード２０が冷却される。
【００２０】
また、高伝熱部材１７が挿入部１の先端部分の外表面に露出しておらず、熱伝導性の悪い材料からなる先端部本体１０が露出しているので、高伝熱部材１７の温度上昇に起因する体内粘膜面の火傷等が発生しない。
【００２１】
なお、本発明は上記実施例に限定されるものではなく、例えば送気ノズル１３に通じる送気通路孔を高伝熱部材１７に穿設して、発光ダイオード２０を空冷によって冷却してもよい。また、図５に示される第２の実施例のように、前後に二分割された先端部本体１０，１０′の間に高伝熱部材１７をサンドイッチ状に配置してもよい。
【００２２】
【発明の効果】
本発明によれば、発光ダイオードを囲んで熱伝導性のよい高伝熱部材を配置すると共に、挿入部の先端に設けられた観察窓の表面に向かって吹き付けられる流体が通過する流体通過路を高伝熱部材に形成したことにより、発光ダイオードから発生する熱が高伝熱部材を通って流体通過路内を通過する流体に伝導されて外部へ排出され、その結果、照明光源として挿入部先端に内蔵された発光ダイオードが冷却され、発光効率と寿命の低下を抑制することができる。
【００２３】
そして、観察窓の表面に向かって流体を吹き付けるための構成は一般の内視鏡には必ず必要なものであるから、内視鏡の挿入部を太くすることなく発光ダイオードの冷却を効果的に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a distal end portion of an endoscope in which a light emitting diode is incorporated as an illumination light source at the distal end of an insertion portion.
[0002]
[Prior art]
In an endoscope, a configuration in which light emitted from a light source lamp disposed outside an insertion portion is transmitted by a light guide fiber bundle inserted into the insertion portion is generally used as an illumination light source. In some cases, the device is simplified by incorporating a light emitting diode.
[0003]
[Problems to be solved by the invention]
However, if the light emitting diode is continuously lit in a narrow and poor heat dissipation environment in the insertion portion of the endoscope, the temperature of the light emitting diode rises, and as a result, the light emission efficiency of the light emitting diode decreases and becomes dark. Or a problem that the lifetime is significantly shortened.
[0004]
Therefore, for example, it is conceivable to cool the light emitting diode by circulating cooling air or water from the outside of the insertion portion. However, if a pipe for cooling the light emitting diode is inserted in the insertion portion, the outer diameter of the insertion portion is considered. The size increases and increases the pain for those undergoing endoscopy.
[0005]
Therefore, the present invention provides a distal end portion of an endoscope that can effectively cool a light emitting diode built in the distal end of the insertion portion as an illumination light source without increasing the thickness of the insertion portion of the endoscope. Objective.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the distal end portion of the endoscope of the present invention has a light emitting diode disposed in an illumination window provided at the distal end of the insertion portion, and illuminates the subject with light emitted from the light emitting diode. At the distal end of the endoscope thus arranged, a highly heat-conductive member having good thermal conductivity is disposed so as to surround the light emitting diode, and the fluid sprayed toward the surface of the observation window provided at the distal end of the insertion portion passes. The fluid passage to be formed is formed in the high heat transfer member.
[0007]
If the outer surface of the distal end portion of the insertion portion is formed of a member having poor thermal conductivity so that the high heat transfer member is not exposed to the outer surface of the distal end portion of the insertion portion, the temperature rise of the high heat transfer member is caused. Does not cause burns on the mucous membrane surface.
[0008]

The water supply nozzle 14 and the air supply nozzle 13 are projected from the end face of the distal end body 10 with the opening facing the surface of the observation window 11, and water and air are ejected toward the surface of the observation window 11 to observe the observation window. 11 surface dirt can be washed.
[0014]
FIG. 1 is a side cross-sectional view of the distal end portion of the insertion portion 1 in a cross section passing through the center of each of the water supply nozzle 14 and the illumination window 12. Is arranged, and the electric wire 21 is passed through the insertion portion 1 at the rear thereof.
[0015]
The light-emitting diode 20 is not directly attached to the tip body 10, but as shown in FIG. 4 illustrating the IV-IV cross section, for example, heat conduction such as copper, aluminum, or an alloy material thereof. A high heat transfer member 17 made of a good metallic material is supported so that the outer peripheral surface of the light emitting portion is surrounded. In FIG. 4, 23 is an image guide fiber bundle, 24 is an air supply passage hole, and 25 is a treatment instrument insertion channel.
[0016]
The high heat transfer member 17 is firmly fitted and fixed in a hole formed in the distal end portion main body 10, so that the high heat transfer member 17 is not exposed to the outer surface of the distal end portion of the insertion portion 1. All portions of the member 17 located on the outer surface side are formed by the tip body 10.
[0017]
And the front-end | tip of the water supply tube 19 through which the water sent from the air / water supply apparatus 8 passes is connected and fixed to the high heat-transfer member 17 from back, and the water supply which connects between this water supply tube 19 and the water supply nozzle 14 A passage hole 18 (fluid passage) is formed in the high heat transfer member 17.
[0018]
In the distal end portion of the endoscope of the embodiment configured as described above, the illumination light emitted from the light emitting diode 20 is irradiated to the subject 100 through the illumination window 12. And if the surface of the observation window 11 is wash | cleaned, the water sent from the external air / water supply apparatus 8 is made into the water supply passage hole by performing water supply operation with the operation valve 4 arrange | positioned at the operation part 3. 18 is ejected from the water supply nozzle 14 toward the surface of the observation window 11.
[0019]
Therefore, the heat generated from the light emitting diode 20 in the lighting state is conducted to the water passing through the water supply passage hole 18 through the high heat transfer member 17 and discharged to the outside. As a result, the light emitting diode 20 is cooled. The
[0020]
Further, since the high heat transfer member 17 is not exposed on the outer surface of the distal end portion of the insertion portion 1 and the distal end body 10 made of a material having poor thermal conductivity is exposed, the temperature of the high heat transfer member 17 is increased. There will be no burns on the mucosal surface of the body due to the rise.
[0021]
In addition, this invention is not limited to the said Example, For example, the air supply passage hole which leads to the air supply nozzle 13 is drilled in the high heat-transfer member 17, and the light emitting diode 20 may be cooled by air cooling. . Further, as in the second embodiment shown in FIG. 5, the high heat transfer member 17 may be arranged in a sandwich between the front and rear end main bodies 10 and 10 ′.

【The invention's effect】
According to the present invention, the high heat transfer member having good thermal conductivity is disposed so as to surround the light emitting diode, and the fluid passageway through which the fluid sprayed toward the surface of the observation window provided at the distal end of the insertion portion passes. By forming on the high heat transfer member, the heat generated from the light emitting diode is conducted to the fluid passing through the fluid passage through the high heat transfer member and discharged to the outside. The light emitting diode built in the LED is cooled, and the reduction in luminous efficiency and lifetime can be suppressed.
[0023]
Since the structure for spraying fluid toward the surface of the observation window is absolutely necessary for a general endoscope, it is effective to cool the light emitting diode without making the insertion portion of the endoscope thick. It can be carried out.
