Description

【考案の詳細な説明】 本考案は内視鏡の操作部に関するものである。[Detailed explanation of the idea] The present invention relates to an operating section of an endoscope.

内視鏡の先端部を胃等の体腔内に挿入し、体腔内の被検
体を観察する場合、内視鏡の先端部の対物レンズ面に汚
物が付着し、観察しにくくなるので内視鏡操作部に設け
られている送気、送水および吸引等の操作部材を操作す
ることにより先端部の対物レンズ面に付着している汚物
を取り除く方法がとられていた。When inserting the tip of an endoscope into a body cavity such as the stomach to observe a subject inside the body cavity, dirt adheres to the objective lens surface of the endoscope, making observation difficult. A method has been used in which dirt adhering to the objective lens surface of the distal end is removed by operating operating members such as air supply, water supply, and suction provided in the operation section.

例えば対物レンズ面に汚物が付着したときはまず送水用
操作部材を操作し、洗浄水を送り汚物を取り除き、レン
ズ面に残っている水滴を送気用操作部材の操作で空気を
送り水を吸き飛ばし、さらに吸引装置により吸引用操作
部材の操作で汚水を吸引排除していた。For example, when dirt adheres to the objective lens surface, first operate the water supply operation member to send cleaning water to remove the dirt, and then operate the air supply operation member to remove the remaining water droplets on the lens surface and send air to absorb the water. The waste water was then removed by suction by operating a suction operation member using a suction device.

また胃等の体腔内を観察する場合観察しやすくするため
送気用操作部材を操作して空気を送り体腔内を膨大させ
ていた。Furthermore, when observing the inside of a body cavity such as the stomach, an air supply operation member is operated to blow air to enlarge the inside of the body cavity to make the observation easier.

このように内視鏡操作部の外周に取付けられた送気用操
作部材、送水用操作部材および吸引用操作部材により観
察しやすくしているが、従来これらの操作部材の位置は
操作部本体を左手で保持しやすくするために、彎曲操作
ノブの軸に対して略直角方向の操作部上面に突出した送
気、送水および吸引等の操作部材が並べて配置されてい
た。In this way, the air supply operation member, water supply operation member, and suction operation member attached to the outer periphery of the endoscope operation section make it easier to observe, but conventionally, these operation members were located at a distance from the main body of the operation section. In order to make it easier to hold with the left hand, operating members for air supply, water supply, suction, etc. that protrude from the upper surface of the operating section in a direction substantially perpendicular to the axis of the curved operating knob are arranged side by side.

このため操作部を把持している指が常に各操作部材の上
に置かれ接眼部を介して術者が観察しているとき無意識
のうちに各操作部材を作動させてしまい、送気を行なう
べきときに送水またその逆を行なってしまう可能性があ
った。For this reason, when the finger gripping the operating section is always placed on each operating member and the operator is observing through the eyepiece, each operating member may be operated unconsciously, causing air supply to be interrupted. There was a possibility that the water supply would be carried out when it should have been carried out, or vice versa.

例えば送気用操作部材を不用意に作動させると体腔内を
必要以上に膨大してしまい患者にとって苦痛を与えるば
かりでなく、患者に疾病がある場合は体腔壁が弱くなっ
ているので損傷を起しやすかった。For example, if the air supply operation member is operated carelessly, the inside of the body cavity becomes larger than necessary, which not only causes pain for the patient, but also causes damage if the patient has a disease because the walls of the body cavity are weakened. It was easy.

また吸引を不用意に行なったりすると静脈瘤等の疾病に
対して出血しすぎて危険な状態になることがあった。In addition, if suction is performed carelessly, excessive bleeding may occur due to diseases such as varicose veins, resulting in a dangerous situation.

このように操作部本体の各操作部材を誤まって操作して
しまうことがあったため各操作部材が何の操作部材であ
るかを表示して誤操作を防止するようにしたものがあっ
たが、術者は無意識のうちに各操作部材を作動させてし
まうことはさけられなかった。In this way, each operating member of the operating unit main body could be operated by mistake, so some devices display the type of operating member each operating member is to prevent erroneous operation. It was inevitable for the operator to operate each operating member unconsciously.

また−回一回表示装置を確認していては観察時間がかか
るとともに内視鏡がら目を離すために体腔内の被検体の
目標物を見失ったりして確認出来ず、ピントのずれを生
じることもあった。In addition, if you check the display device once, it takes time to observe, and if you take your eyes off the endoscope, you may lose sight of the subject's target in the body cavity and cannot confirm it, resulting in a loss of focus. There was also.

また意識して各操作部材から指を離していようとすると
指が無理な形を取らねばならず術者にとって苦痛となっ
ていた。Furthermore, when the operator consciously tries to release his fingers from each operating member, his fingers have to assume an unreasonable shape, which is painful for the operator.

そこで本考案は上述せるところに鑑み比較的容易に送気
、送水および吸引等の操作において、誤操作を防止する
ことができるとともに、操作しやすい内視鏡操作部を提
供することを目的としたものである。Therefore, in view of the above, the present invention aims to provide an endoscope operating section that can relatively easily prevent erroneous operations during operations such as air supply, water supply, and suction, and that is easy to operate. It is.
