Then, an uptown angle knob 1 is attached to the operation section 4 of the endoscope.
A plurality of operating knobs such as 0 and right-left angle knobs 11 are coaxially rotatably mounted, and the distal end of the insertion section 5 can be bent vertically or horizontally remotely.

る。 Specifically, Up Town Angle Knob 10,
A sprocket is attached to each rotating shaft of the right-left angle knob 11, and a chain is connected to each of the sprockets. A structure is used in which each chain is connected to the curved section 7 via an operating wire (none of which is shown) inserted into the flexible tube section 6, and the curved section 7 is connected by rotating the uptown angle knob 10. It is curved in the vertical direction, and by rotating the right-left angle knob 11, the curved portion 7 is curved in the left-right direction.

面１３ａへ移行することにより行なわれる。 By the way, conventionally, an operation knob for performing such a bending operation of the tip of the insertion portion has a plurality of claw portions 12 protruding from the outer peripheral surface, as shown in FIG. In addition to forming troughs 13 between these claws 12, each side wall surface of the claws 12 and troughs 13 has finger contact surfaces 12a parallel to the axial direction of the rotating shaft 15. ..., 13a... are used. When the operator rotates these operating knobs (uptown angle knob 10, right left angle knob 11), the operating section 4
While grasping the finger, first touch the finger contact surface 12 of the claw
This is done by placing the thumb on point a, starting a rotation operation with the pad of the finger parallel to the rotation axis 15, and then transferring the operation to the finger contact surface 13a of the trough 13.

滑り易くなる。[Problems to be solved by the invention] By the way, in such a rotational operation, the tip of the thumb is gradually bent as the operating knob is rotated, and
It leans against. However, since the finger contact surface 13a of the operating knob is a surface parallel to the axial direction of the rotation shaft 15, especially when the thumb moves to the trough 13, the fingertip moves along the finger contact surface 13a as shown in FIG. It gets sticky and slippery.

とで操作ノブに適確に指の力を掛けにくくなり、
操作性も悪くしていた。 Therefore, it was not possible to stably press the fingertip of the operator against the finger contact surface 13a of the trough 13, resulting in a poor contact feeling. Moreover, this makes it difficult to apply proper finger force to the operation knob,
The operability was also poor.
この考案は、このような問題点に着目してなさ

る。 In one embodiment, the main part of the present invention is applied to an uptown angle knob 10 (operation knob) arranged on the main body side of the operation section 2. That is, as shown in FIG.
Set a to the uptown angle knob 10 as before.
formed from a surface parallel to the axial direction of the rotating shaft 10a,
Finger contact surface 23a formed by the side wall surface of the valley portion 13
, the rotation axis 15 of the uptown angle knob 10
An inclined surface 23 inclined substantially linearly with respect to the axial direction of the
It is formed by b. For details, see the inclined surface 23b.
The rotation axis 10a increases as it moves away from the operating section 2.
It is formed of a surface (non-parallel surface) that slopes in a direction in which the distance between the center and the axis of the surface gradually decreases.
なお、操作部４から外側に配置されるライトレ

のノブが用いられている。 Note that the right-left angle knob 11 disposed outside of the operating section 4 is a disk-shaped knob having a uniform uneven surface (knurling) formed over the entire circumference of the outer circumferential surface.
しかして、こうしたアツプタウンアングルノブ
１０を使つて彎曲操作を行なうときは、術者が内
視鏡の操作部４を握つた状態で、従来と同様にま
ず、第２図および第３図の実線に示されるように
爪部１２の指当て面２２ａに親指を当てる。 Therefore, when performing a bending operation using such an up-down angle knob 10, while the operator is grasping the operating section 4 of the endoscope, first, as in the conventional case, As shown in FIG. 2, place the thumb on the finger contact surface 22a of the claw portion 12.
ここで、指先は回転軸１０ａと平行な状態とな

て面２２ａの方向とは略一致する。つまり、第３
図中に示す矢印F1のように指当て面２２ａと直
角な方向からアツプタウンアングルノブ１０の軸
心へ力が加つていく安定した進行ができる状態と
なる。 Here, since the fingertip is in a state parallel to the rotation axis 10a, the direction substantially coincides with the direction of the finger contact surface 22a formed by a plane parallel to the rotation axis 15. In other words, the third
A state is reached in which a force is applied to the axis of the uptown angle knob 10 from a direction perpendicular to the finger contact surface 22a, as indicated by arrow F1 in the figure, allowing stable movement.
ついで、この状態から親指で回転操作を始めれ

行して回転を継ぎ、彎曲管７の彎曲操作を継続し
ていけば、挿入部先端が上方向、又は下方向へ彎
曲していく。 Next, when a rotation operation is started with the thumb from this state, the chain and operation wire (none of which are shown) are pushed and pulled, and the curved tube 7 begins to curve. Then, as shown in FIGS. 2 and 3, if the thumb is moved from the claw part 12 to the finger rest part 23a of the valley part 13 and the rotation is continued and the bending operation of the curved tube 7 is continued, the insertion part The tip curves upward or downward.
こうした回転操作における術者の親指は、アツ
プタウンアングルノブ１０の回転に伴い徐々に屈
曲されていき、指当て面２３ａに移行した後は、
指先が第３図および第４図に示されるように回転
軸１５に対して傾いていく。 During such a rotation operation, the operator's thumb is gradually bent as the uptown angle knob 10 is rotated, and after moving to the finger contact surface 23a,
The fingertip becomes inclined with respect to the rotating shaft 15 as shown in FIGS. 3 and 4.
ここで、谷部１３の指当て面２３ａは軸方向に
対し傾斜した傾斜面２３ｂから形成されている。
しかるに、指当て面２３ａに親指を押し当てたと
きにも、術者の親指の傾き方向と谷部１３の指当
て面２３ａの傾斜方向とを一致させることができ
ることとなる。 Here, the finger contact surface 23a of the valley portion 13 is formed of an inclined surface 23b inclined with respect to the axial direction.
However, even when the thumb is pressed against the finger contact surface 23a, the inclination direction of the operator's thumb and the inclination direction of the finger contact surface 23a of the valley portion 13 can be matched.
これ故、術者の指先から谷部１３の指当て面２
３ａに加わる力の方向としては、第４図中の矢印
F2にも示されるように傾斜面２３ｂと直角な方
向から作用させることができ、術者の指先が操作
部４の本体側から離れる方向に向けられることを
確実に防止することができる。 Therefore, from the operator's fingertip to the finger contact surface 2 of the trough 13.
The direction of the force applied to 3a is indicated by the arrow in Figure 4.
As shown in F 2 , the actuator can be operated from a direction perpendicular to the inclined surface 23b, and it is possible to reliably prevent the operator's fingertips from being directed away from the main body side of the operating section 4.
したがつて、術者の親指が爪部１２に押し当て
ていても、又谷部１３に押し当てていても、常に
指先を安定的に指当て面２２ａ、又は指当て面２
３ａに押し当てることができ、指先の感触感およ
び操作性を向上させることができる。 Therefore, even if the operator's thumb is pressed against the nail portion 12 or against the valley portion 13, the fingertip is always stably pressed against the finger contact surface 22a or the finger contact surface 2.
3a to improve the tactile sensation and operability of the fingertips.
しかも、指当て面２３ａを傾斜面２３ｂで形成
したことで、アツプタウンアングルノブ１０のラ
イトレフトアングルノブ１１側が小径となるの
で、親指でのライトレフトアングルノブ１１の操
作がやりやすくなる利点をもたらす。 Furthermore, by forming the finger contact surface 23a with the inclined surface 23b, the right left angle knob 11 side of the uptown angle knob 10 has a smaller diameter, which provides the advantage of making it easier to operate the right left angle knob 11 with the thumb. .
なお、一実施例では回転軸１５の軸方向に対し
略直線的に傾斜させた傾斜面２３ｂを指当て面２
３ａに適用したが、これに限らず、回転軸１５の
軸方向に対し彎曲させた彎曲面、回転軸１５の軸
方向に対し傾斜させた彎曲面等でもよい。 In one embodiment, an inclined surface 23b that is inclined substantially linearly with respect to the axial direction of the rotating shaft 15 is used as the finger rest surface 2.
3a, but the present invention is not limited thereto, and may be a curved surface curved relative to the axial direction of the rotating shaft 15, a curved surface inclined relative to the axial direction of the rotating shaft 15, or the like.
また、この考案を一実施例ではアツプタウンア
ングルノブ１０に適用したが、ライトレフトアン
グルノブ１１に適用してもよい。 Furthermore, although this invention is applied to the uptown angle knob 10 in one embodiment, it may also be applied to the right left angle knob 11.
