Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In the following description, the front-rear direction defines the distal end side of theinsertion portion 12 of theendoscope 10 as “front”, and the proximal end side of theinsertion portion 12 as “rearward”. 3 and 4 is a reference. Theendoscope 10 shown in FIG. 1 is an electronic endoscope for a nasal cavity, and includes anoperation gripping part 11 having a substantially U shape in side view, and anoperation gripping part 11. Aflexible insertion portion 12 extending forward from the front end (a portion near the front end portion of theinsertion portion 12 is a curved portion 13), and auniversal tube 14 extending from the lower end of theoperation gripping portion 11 to the opposite side of theinsertion portion 12. It is equipped with. As shown in the figure, the lower end surface of theoperation gripping portion 11 is provided with a bend-proof rubber 15 having a truncated conical cylindrical shape, and this bend-stoppingrubber 15 is connected to the base end portion of the universal tube 14 (with theoperation gripping portion 11 and ). Theuniversal tube 14 has flexibility, and a connector (not shown) provided at the rear end thereof is connected to a processor (image processing device / light source device) (not shown) and a suction source. Furthermore, since the processor is connected to a monitor (not shown), when an observation image obtained by an objective lens (not shown) provided on the distal end surface of theinsertion unit 12 is captured by an imaging device provided in theinsertion unit 12. This observation image (moving image) is displayed on the monitor.

次に操作把持部11の構造について詳しく説明する。
操作把持部11は2つの大きな構成要素を具備している。即ち、略前後方向に延びると共に操作把持部11の上部をなす操作部20と、操作部20の後端部(下端部)から後ろ斜め下方に向かって延びる把持部21と、を具備している(図1及び図2に操作部20と把持部21の境界線BLを示す)。操作部20と把持部21は共に左右対称形状をなす中空の筒状部材であり、操作部20の下端部と把持部21の上端部は同じ断面形状の開口部となっている。そして、操作部20の下端部と把持部21の上端部を接合することにより操作把持部11を構成している。
操作部20は、後部22と、後部22より小径で後部22から前方に向かって延出する略円筒形状の前部23と、を有しており、後部22の左右両側面には側面視円形をなす垂直面である円形偏平面24が形成してある。
操作部20の右側の円形偏平面24には後部22の右側壁部を左右方向に貫通する回転軸25が設けてあり、回転軸25は把持部21の内部に設けた軸受けによってその軸線(左右方向に延びている)回りに回転可能に支持されている。この回転軸25の右端部には正面視略L字形状をなす操作レバー26の基端部が固定してある。操作レバー26は、側面視において円形偏平面24の径方向に延びかつその基端部が回転軸25の右端部に固定された径方向延出部27と、径方向延出部27の先端部から左側に向かって直線的に延びる被操作部28と、を有している。操作レバー26は回転軸25を中心に図示を省略した上限位置と下限位置の間を回転可能である。
さらに、操作部20の内部において回転軸25の周囲には捻りコイルばね(トーションばね)が設けてあり、この捻りコイルばねの端部が操作部20の内壁に係止してある。そのため、操作レバー26はこの捻りコイルばねの回転付勢力によって図1及び図2に示す初期位置に回転付勢(保持)されている。
図2に示すように術者が左手Aの親指A1を操作レバー26の被操作部28に載せて操作レバー26を上限位置側に回転させると、操作部20及び挿入部12の内部に配設した回転軸25と湾曲部13を連係する湾曲操作機構の働きにより湾曲部13が下方に湾曲する。一方、術者が親指A1で操作レバー26を下限位置側に回転させると湾曲操作機構の働きにより湾曲部13が上方に湾曲する。
Next, the structure of theoperation grip 11 will be described in detail.
Theoperation grip 11 has two large components. In other words, it includes anoperation unit 20 that extends substantially in the front-rear direction and forms the upper part of theoperation gripping unit 11, and agripping unit 21 that extends obliquely downward and rearward from the rear end (lower end) of theoperation unit 20. (The boundary line BL of theoperation part 20 and theholding part 21 is shown in FIG.1 and FIG.2). Both theoperation part 20 and thegrip part 21 are hollow cylindrical members having a symmetrical shape, and the lower end part of theoperation part 20 and the upper end part of thegrip part 21 are openings having the same cross-sectional shape. And theoperation grip part 11 is comprised by joining the lower end part of theoperation part 20, and the upper end part of thegrip part 21. FIG.
Theoperation unit 20 includes arear part 22 and a substantially cylindricalfront part 23 having a smaller diameter than therear part 22 and extending forward from therear part 22. A circularflat surface 24 is formed as a vertical surface.
Arotary shaft 25 penetrating the right side wall portion of therear portion 22 in the left-right direction is provided on the circularflat surface 24 on the right side of theoperation unit 20, and therotation shaft 25 is connected to the axis (right and left) by a bearing provided inside thegrip portion 21. It extends in the direction) and is supported so as to be rotatable. A base end portion of an operation lever 26 having a substantially L shape in a front view is fixed to the right end portion of the rotatingshaft 25. The operation lever 26 includes a radial extension portion 27 that extends in the radial direction of the circularlyflat surface 24 in a side view and a base end portion fixed to the right end portion of therotary shaft 25, and a distal end portion of the radial extension portion 27. And an operatedportion 28 extending linearly from the left side to the left side. The operation lever 26 can rotate between an upper limit position and a lower limit position (not shown) around therotation shaft 25.
Further, a torsion coil spring (torsion spring) is provided around therotary shaft 25 in theoperation unit 20, and an end of the torsion coil spring is locked to the inner wall of theoperation unit 20. Therefore, the operation lever 26 is rotationally biased (held) to the initial position shown in FIGS. 1 and 2 by the rotational biasing force of the torsion coil spring.
As shown in FIG. 2, when the operator places the thumb A1 of the left hand A on the operatedportion 28 of the operation lever 26 and rotates the operation lever 26 to the upper limit position side, the operator is disposed inside theoperation portion 20 and theinsertion portion 12. The bendingportion 13 is bent downward by the action of the bending operation mechanism that links therotating shaft 25 and the bendingportion 13. On the other hand, when the surgeon rotates the operation lever 26 to the lower limit position side with the thumb A1, the bendingportion 13 is bent upward by the action of the bending operation mechanism.

操作部20の後部22の下部の前面には下側ボタン取付面30と、下側ボタン取付面30の直上に位置すると共に下側ボタン取付面30よりも前方に位置する上側ボタン取付面31と、が形成してある。図3に示すように、下側ボタン取付面30の左右方向の中央部には前後方向に出没自在である吸引ボタンB1が突設してあり、上側ボタン取付面31には共に前後方向に出没自在であるシャッターボタンB2と画像記憶ボタンB3が左右に並べて突設してある。さらに、操作部20の後部22の上部の前面には上部ボタン取付面32が形成してあり、この上部ボタン取付面32には画像エンハンスレベル変更ボタンB4と測光方式切替ボタンB5が左右に並べて突設してある。吸引ボタンB1を下側ボタン取付面30側に押し込むと、上記吸引源の吸引力が内視鏡10の内部に配設した吸引管(図示略)に及ぶので、挿入部12の先端面に形成した吸引口から患者の体液等を吸引可能となる。シャッターボタンB2を上側ボタン取付面31側に押し込むと、シャッターボタンB2を押した瞬間に上記撮像素子が撮像した画像が静止画像として上記モニタに表示される。さらに画像記憶ボタンB3を上側ボタン取付面31側に押し込むと、シャッターボタンB2を押し込むことにより得られた静止画像が上記プロセッサに内蔵した記憶手段に記憶される。画像エンハンスレベル変更ボタンB4を上部ボタン取付面32側に押し込んだ場合は画像エンハンスレベルが変更され、測光方式切替ボタンB5を上部ボタン取付面32側に押し込んだ場合は測光方式が切替わる。
図3に示すように、シャッターボタンB2と画像記憶ボタンB3は内視鏡10の左右方向の中心を通って上下方向に延びる中心線CL1に関して左右対称をなす位置に位置しており、画像エンハンスレベル変更ボタンB4と測光方式切替ボタンB5も中心線CL1に関して左右対称をなす位置に位置している。さらに、シャッターボタンB2と画像エンハンスレベル変更ボタンB4は正面視において前部23の中心を通って左右方向に延びる中心線CL2に関して上下対称をなす位置に位置しており、画像記憶ボタンB3と測光方式切替ボタンB5も中心線CL2に関して上下対称をなす位置に位置している。さらに、シャッターボタンB2、画像記憶ボタンB3、画像エンハンスレベル変更ボタンB4及び測光方式切替ボタンB5の外形は同一である。
On the front surface of the lower portion of therear portion 22 of theoperation unit 20, there are a lowerbutton mounting surface 30, an upperbutton mounting surface 31 positioned immediately above the lowerbutton mounting surface 30 and positioned in front of the lowerbutton mounting surface 30. , Is formed. As shown in FIG. 3, a suction button B <b> 1 that protrudes and retracts in the front-rear direction protrudes from the center of the lowerbutton attachment surface 30 in the left-right direction, and both of the upper button attachment surfaces 31 appear in the front-rear direction. A free shutter button B2 and an image storage button B3 are juxtaposed side by side. Further, an upperbutton attachment surface 32 is formed on the front surface of the upper portion of therear portion 22 of theoperation unit 20, and an image enhancement level change button B4 and a photometry method switching button B5 are arranged on the upperbutton attachment surface 32 side by side. It is set up. When the suction button B1 is pushed into the lowerbutton mounting surface 30 side, the suction force of the suction source reaches a suction tube (not shown) disposed in theendoscope 10, and thus formed on the distal end surface of theinsertion portion 12. The patient's body fluid and the like can be sucked from the suction port. When the shutter button B2 is pushed into the upperbutton mounting surface 31 side, an image captured by the image sensor at the moment when the shutter button B2 is pressed is displayed as a still image on the monitor. When the image storage button B3 is further pushed into the upperbutton mounting surface 31, the still image obtained by pushing the shutter button B2 is stored in the storage means built in the processor. When the image enhancement level change button B4 is pushed into the upperbutton attachment surface 32 side, the image enhancement level is changed, and when the photometry method switching button B5 is pushed into the upperbutton attachment surface 32 side, the photometry method is switched.
As shown in FIG. 3, the shutter button B2 and the image storage button B3 are located at positions that are symmetric with respect to a center line CL1 that extends in the up-down direction through the center in the left-right direction of theendoscope 10, and the image enhancement level. The change button B4 and the photometry method switching button B5 are also located at positions symmetrical with respect to the center line CL1. Further, the shutter button B2 and the image enhancement level change button B4 are located at positions that are vertically symmetrical with respect to a center line CL2 that extends in the left-right direction through the center of thefront portion 23 when viewed from the front. The switching button B5 is also located at a position that is vertically symmetric with respect to the center line CL2. Further, the outer shapes of the shutter button B2, the image storage button B3, the image enhancement level change button B4, and the photometry method switching button B5 are the same.

次に、内視鏡10を術者が把持して使用する要領について説明する。
図2に示すように、術者が左手Aで操作部20及び把持部21を握る際には、操作部20及び把持部21の左側面に掌を接触させ、小指A5を把持部21の前側把持面35及び右側面に掛ける。さらに、薬指A4を吸引ボタンB1の前端面に接触させ、中指A3をシャッターボタンB2及び画像記憶ボタンB3の前端面に接触させ、人差し指A2を画像エンハンスレベル変更ボタンB4及び測光方式切替ボタンB5の前端面に接触させ、掌における親指A1に連なる部分(大菱形骨や舟状骨に対応する部分)あるいはその近傍を把持部21の後面に接触させる。
このように、人差し指A2を前部23の上方に位置する画像エンハンスレベル変更ボタンB4及び測光方式切替ボタンB5の前端面に接触させると、人差し指A2によって操作部20における前部23より上側の部分が支持されることになるので、前部23より上側の部分を支持せず前部23より下側の部分のみを支持する(吸引ボタンB1、シャッターボタンB2、画像記憶ボタンB3の前端面のみを指で押さえる)場合に比べて把持状態が安定する。従って、吸引ボタンB1、シャッターボタンB2、画像記憶ボタンB3、画像エンハンスレベル変更ボタンB4、測光方式切替ボタンB5を正確かつ円滑に操作できる。
さらに、前部23の上方に位置する画像エンハンスレベル変更ボタンB4及び測光方式切替ボタンB5を人差し指A2で押さえるので、仮に前部23の下方に位置するシャッターボタンB2を中指A3によって強い力で押しても内視鏡10全体が不意にがたつくことがない。そのため、シャッターボタンB2を押した際に、モニタに表示された画像(動画)がぶれたり、シャッターボタンB2を押すことにより得られる静止画像にぶれが生じるのを防止できる。
Next, a procedure for the operator to grasp and use theendoscope 10 will be described.
