Abstract

PROBLEM TO BE SOLVED: To provide an endoscope having a simple external shape so as to faciliate the cleaning thereof after use even though filth is sucked up, by providing at least one of passage communicated with a flushing port, and a nozzle connected to the passage between the bottom part of an outer sheath and the front end face of the insertion part of the endoscope.
SOLUTION: Water fed from a water feed source 21 into a prot 19 flows through a channel (passage) 18 to the front end of the latter, and impinges upon the inner side wall surface of a bottom part 31 so as to be turned by its direction. Then, it flows from out a nozzle and onto an objective cover glass pane 33 so as to wash off filth or water drops on the objective glass pane. Further, a suction source 22 is connected to the port 19 so as to feed air in order to blow off filth and water drops from the glass pane 33, thereby it is possible to remove blurring or dirt sticking to the pane 33, After use, an inner sheath 3 and the outer sheath 4 can be disassembled from each other, and accordingly, they can be washed independent from each other. Further, an inner sheath insertion part 7 and an outer sheath insertion part 9 have simple shapes with no closed spaces, and accordingly, they can be easily washed.

【0001】 [0001]

【発明の属する技術分野】本発明は、内視鏡挿入部に被嵌するシースを使用する内視鏡装置に関する。 The present invention relates to relates to an endoscope apparatus that uses a sheath fitted over the endoscope insertion portion.

【0002】 [0002]

【従来の技術】内視鏡観察下での検査診断や手術を行う際、体腔内に挿入設置した内視鏡の対物レンズの外表面は曇ったり、血液、水しぶき、煙等で汚れ易く、その結果、観察視野が悪化することが多くしばしば起こる。 When performing laboratory diagnosis and surgery of the Prior Art Endoscopic observation under the outer surface or clouded objective lens of the endoscope inserted placed into a body cavity, blood, Splashes, easily contaminated by smoke or the like, the a result, it is often often happens that the observation field is deteriorated. 従来ではこれを解消するため、内視鏡の先端に、対物レンズの近くにノズルを設置して、その対物レンズの外表面に送水と送気を行って洗浄していた。 In the conventional to solve this problem, the distal end of the endoscope, by installing a nozzle close to the objective lens, was washed by performing the air and water on the outer surface of the objective lens.

【0003】一般的には内視鏡本体内に送水・送気チャンネルを形成し、このチャンネルを通じて送水・送気を行うが、特開平6−189893号公報に開示される内視鏡装置では内視鏡挿入部にパイプ形状のシースを被せるとともに、そのシースと内視鏡挿入部の間に空間を形成し、ここの空間を送水チャンネルとするようにしている。 [0003] Generally in forming the water-air channels in the endoscope body, performs the water-air through the channel, the inner in the endoscope apparatus disclosed in Japanese Patent Laid-Open No. 6-189893 together covering the sheath pipe shaped endoscope insertion portion, a space is formed between the sheath and the endoscope insertion portion, and the individual space as a water channel.

【0004】 [0004]

【発明が解決しようとする課題】特開平6−18989 The object of the invention is to be Solved by JP-A-6-18989
3号公報に開示される内視鏡装置は内視鏡挿入部にパイプ形状のシースを被せ、そのシースと内視鏡挿入部の間に形成される隙間を送水チャンネルとする。 The endoscope apparatus disclosed in 3 publication is covered with a sheath pipe-shaped insertion part of the endoscope, the gap formed between the sheath and the endoscope insertion portion with water channels. ところが、 However,
その送水チャンネルを通じて送水を行うと、その送水が直接に内視鏡挿入部の外表面上に触れながら手元から先端側へ向って流れる。 Doing water through its water channel, it flows from the proximal to the distal end side while touching on the outer surface of the endoscope insertion portion on the water supply directly. このため、冷たい水を流すと、内視鏡挿入部が直ちに冷やされ、内視鏡挿入部の内部のレンズ群が冷やされてレンズの表面に水滴が付き、これが原因で内視鏡による観察像が曇ってしまうという現象が起きる。 Therefore, when flowing cold water, cooled endoscope insertion portion immediately attached water drops on the surface of the endoscope insertion portion inside lens group is cooled by a lens, which is an observation image by the endoscope due phenomenon resulting in cloudy occurs.

【0005】また、特開平6−189893号公報に開示されるように、内視鏡挿入部に沿わせて管路を形成する場合には、その管路が細長い閉空間を形成することになるため、その管路の内部に汚物が詰まり易い。 Further, as disclosed in Japanese Unexamined Patent Publication No. 6-189893, when allowed along the endoscope insertion portion forms a conduit would the conduit forms between the elongated closed space Therefore, easy dirt clogging the inside of the pipe. その結果、管路にて内視鏡挿入部の先端から汚れ等を吸引できないし、また、使用後、器材の洗浄がしにくくなる。 As a result, do not be aspirated dirt from the tip of the endoscope insertion portion in the conduit, also after use, it is difficult to cleaning of equipment. また、細長い管路を形成することで、管路の強度が不足したり、管路形成のための複雑な製造工程が必要となり、 Further, by forming an elongated conduit, or insufficient strength of the conduit, it is required complicated manufacturing process for the pipe formation,
原価が嵩む原因ともなる。 Also cause the increase is the cost.

【0006】さらに、内視鏡挿入部に管路を沿わせて形成することから、挿入部全体の外観形状が円筒でなく、 Furthermore, since the formation by along the pipe insertion part of the endoscope, the overall exterior shape insertion portion is not cylindrical,
凹凸を有する形状にしなければならない場合もある。 There is a case that must be in a shape having a concave-convex. その場合には患者に損傷を与えたり、腹腔鏡下外科手術用のトラカールとの組み合わせ時の気密が保てない等の問題も起きる。 Or damaging the patient in that case, also it occurs problems such as airtightness can not be maintained at the time of combination with trocar for laparoscopic surgery.

【0007】本発明は前記課題に着目してなされたもので、その目的とするところは仮に冷えた送水を流しても内視鏡が冷えにくく、また、内視鏡挿入部の先端より汚物を吸引した場合でも、使用後の器材の洗浄が容易であり、さらに強度が強く、挿入部外観形状が単純なものを提供することにある。 [0007] The present invention has been made in view of the above problems, the place of interest is hardly cooled endoscope be shed if cold water supply, also the dirt from the tip of the endoscope insertion portion even when the suction, it is easy to wash after use equipment, further strength is strong, in that the insertion portion external shape provides simple.
