- the lower surface 42a of the connector 42 is placed and supported on the IF, and the lower surface of the universal cord 16 is supported near the base of the thumb TH.
- the thumb TH is arranged from the first surface 62 to the second surface 64 through the lower side of the universal cord 16.
- the thumb TH can be placed in the vicinity of the switch 56d disposed at a position close to the user in the switch unit 56 or the convex portion 36a of the UD bending operation knob 36.
- the thumb ball of the thumb TH is in the vicinity of the first surface 62 and the fourth surface 68 and on the left side of the fifth surface 72 and the sixth surface 74.
- the index finger IF is disposed at a position where the pressing body 52a of the first pressing valve unit 52 of the switch assembly 40 can be operated, or is disposed at a position where the pressing body 54a of the second pressing valve unit 54 can be operated. Further, the index finger IF may be disposed on the switch 56 a of the switch unit 56 of the switch assembly 40.
- the middle finger MF is arranged at a position where the pressing body 52a of the first pressing valve unit 52 can be operated, or arranged at a position where the UD bending operation knob 36 can be supported.
- the operation portion of the conventional endoscope forms one protruding corner portion by three surfaces including the third surface, the fourth surface, and the protruding surface (the lower surface of the protruding portion).
- the UD curving operation knob When the UD curving operation knob is supported, the projecting corners formed by the three surfaces separated from the UD curving operation knob 36 interfere when the UD curving operation knob is operated with the middle finger or the ring finger.
- the operation unit 14 when supporting the UD bending operation knob 36, it is necessary to arrange the middle finger MF and the ring finger RF on the projecting surface 70a of the projecting unit 70.
- the operation unit 14 according to this embodiment forms the inclined surface 92 continuously on the lower surface (projecting surface) 70 a of the projecting portion 70. For this reason, the projecting corner portion is not formed by the three surfaces of the third surface 66, the fourth surface 68, and the projecting surface 70a of the projecting portion 70.
- the UD bending operation knob 36 when the UD bending operation knob 36 is supported by the middle finger MF or the ring finger RF, it is possible to prevent the middle finger MF or the ring finger RF from interfering with the protruding portion 70 at a position separated from the UD bending operation knob 36. Therefore, when the UD bending operation knob 36 is supported by the middle finger MF or the ring finger RF, an excessive force is not applied to the fingers MF and RF, and the support can be easily performed. Therefore, the bases of the fingers MF and RF can be brought closer to the UD bending operation knob 36 than the operation unit of the conventional endoscope. In addition, even if the inclined surface 92 according to this embodiment is formed as a curved surface, it can be regarded as substantially flat and can prevent the finger MF from being caught.
- the UD bending operation knob 36 may be rotated by the middle finger MF or the ring finger RF.
- the inclined surface 92 is continuously formed on the lower surface (projecting surface) 70 a of the projecting portion 70.
- the projecting corner portion is not formed by the three surfaces of the third surface 66, the fourth surface 68, and the projecting surface 70a of the projecting portion 70. Therefore, since an excessive force is not applied to the fingers MF and RF by the inclined surface 92, it is easy to rotate the UD bending operation knob 36 with the fingers MF and RF.
- a device operation unit) 14 and an endoscope (intra-hole introduction device) 10 having such an operation unit 14 can be provided.
- the inclined surface 92 described in the second embodiment is formed on the fourth surface 68 side as shown in FIG. It is also preferable to form an inclined surface having substantially the same shape on the second surface 64 side. At this time, the inclined surface 92 on the fourth surface 68 side may be formed or may not be formed.
- the inclined surface 82 described in the first embodiment is arranged on the fourth surface 68 side (a position separated from the UD bending operation knob 36), and the inclined surface 92 described in the second embodiment is provided on the fourth surface 68 side. It is also preferable to form it on the second surface 64 side (position close to the UD bending operation knob 36).

Abstract
Description
内視鏡(孔内導入装置)10は、孔内に挿入される挿入部12と、ユーザの片手、特に左手で把持されて挿入部12を含む内視鏡10を適宜に操作するのに用いられる操作部14と、内視鏡10を制御する図示しない制御ユニットに接続されるユニバーサルコード16とを有する。
内視鏡10は、図示しないが、その内部に、孔内を照明する公知の照明光学系、及び、照明光学系で照明された孔内を撮像して観察する公知の観察光学系を有する。内視鏡10はさらに、観察光学系の図示しない対物レンズ等を洗浄したり、生体組織や血液等を吸引可能な公知の送気・送水・吸引ユニットを有する。
押圧スイッチとしての第1押圧弁ユニット52は後述する第3面66に配置され、第2把持部34及び挿入部12に近接する側(下側)にあり、挿入部12の先端硬質部22の先端から気体を吐出させる送気や液体を吐出させる送水を行うのに用いられる。第2押圧弁ユニット54は、挿入部12に離隔する側(上側)にあり、挿入部12の先端硬質部22の先端にある生体組織や血液等を吸引するのに用いられる。第1及び第2押圧弁ユニット52,54は、内視鏡10の挿入部12の先端からユニバーサルコード16のうち操作部14に対する遠位端に挿通された、上述した公知の送気・送水・吸引ユニットの一部である。なお、この実施形態に係る第1及び第2押圧弁ユニット52,54は同一サイズかつ外観が同一形状であることが好ましい。また、第1及び第2押圧弁ユニット52,54は円筒形状であることが好ましい。
また、第1把持部32のうち、第2押圧弁ユニット54の上側には、複数のスイッチ(押圧スイッチ)56a,56b,…を有するスイッチユニット56が配置されている。スイッチ56a,56b,…の機能は適宜に設定される。スイッチユニット56のスイッチの1つは、例えば静止画を撮像するのに、内視鏡10の図示しない制御ユニットで機能が設定されて用いられる。また、他のスイッチの1つは、例えば、照明光を通常光(白色光)と特殊光(例えば蛍光)とを切り替えたりするのに図示しない制御ユニットで機能が設定されて用いられる。
従来の内視鏡の操作部とは異なり、この実施形態に係る内視鏡10の操作部14は、第1把持部32のうちUD湾曲操作ノブ36が配置された第2面と第3面との間に傾斜面82が形成されている。このため、例えば中指MFや薬指RF等でUD湾曲操作ノブ36の位置を保持しようとする際に、突出部70により指MF,RFが干渉するのを防止することができる。このため、例えば手が比較的小さいユーザであっても、この実施形態に係る操作部14は、指MF,RFが干渉するのが防止されているので、UD湾曲操作ノブ36の位置を容易に支持することができる。もちろん、比較的手が大きいユーザにとっても、指MF,RFが干渉するのが防止され、UD湾曲操作ノブ36の位置を容易に保持することができる。したがって、ユーザは、中指MF又は薬指RFでUD湾曲操作ノブ36を支持する作業を行う場合にストレスを低減させた状態で作業を行うことができる。
傾斜面92は、傾斜縁部94に加えて、第4面68に形成された第2傾斜縁部96、さらには、第2傾斜縁部96よりも突出面70aに近接する位置に形成された第3傾斜縁部98により形成されている。傾斜面92は平面として形成されていても良く、傾斜縁部94,96,98により規定される面に対して法線方向に突出した曲面として形成されていても良い。
