クタ９が取り付けられている。操作部４には接眼
部１０と上記湾曲操作装置２の操作側部分とが設
けられている。 The endoscope 1 shown in FIG. 1 employs a conventional bending operation device 2 of the lever operation type. This endoscope consists of an insertion section 3, an operating section 4, and a universal cord 5, and the insertion section 3 has a distal end component 8 connected to the distal end of a flexible tube 6 via a curved tube 7. A connector 9 for connecting to a light source device (not shown) is attached to the extending end of the universal cord 5. The operation section 4 is provided with an eyepiece section 10 and an operation side portion of the bending operation device 2.
上記湾曲操作装置２の操作レバー１１は枢支軸
１２を介して上記操作部４に枢着されていて、操
作部４の長手軸方向ｌに沿つて回動できるように
なつている。 The operating lever 11 of the bending operating device 2 is pivotally connected to the operating section 4 via a pivot shaft 12, and is rotatable along the longitudinal axis l of the operating section 4.
そして、医師が湾曲操作を行なう場合は片方の

するためには親指の第１関節を曲げたり伸ばした
りしなければならない。 When the doctor performs the bending operation, he/she grips the operating section 4 with one hand and operates the operating lever 11 with the thumb of that hand. That is, as shown in FIG. 2, the thumb is placed on the head of the operating lever 11 in the direction indicated by the arrow, that is, in the longitudinal axis direction l of the operating section 4.
Move in the direction along. However, in order to achieve this movement, the first joint of the thumb must be flexed and extended.
この親指の第１関節を曲げたり伸ばしたりする
運動を繰り返すことは人間にとつて著しく疲労を
与えるものであり、また、操作量が望むとうりに
なりにくく不安定な操作になりやすい、つまり、
内視鏡の診断操作を円滑かつ迅速になし得ず、操
作性が劣り、さらに疲労しやすいものであつた。 Repeating this exercise of bending and stretching the first joint of the thumb is extremely tiring for humans, and the amount of operation is difficult to achieve as desired, which tends to result in unstable operation.
The diagnostic operation of the endoscope could not be performed smoothly and quickly, the operability was poor, and the user was easily fatigued.
本発明は上記事情に着目してなされたもので、
その目的とするところは安定した円滑かつ迅速な
湾曲操作が可能で疲れにくい操作性のよい内視鏡
の湾曲操作装置を提供することにある。 The present invention has been made focusing on the above circumstances,
The purpose is to provide an endoscope bending operation device that is capable of stable, smooth, and quick bending operations and is easy to operate without causing fatigue.
以下、本発明の第１の実施例を第３図ないし第
８図にもとづいて説明する。また、この実施例の

接するようになつている。 The operating lever 11 in this embodiment is made of a relatively thick belt-shaped plate bent into an L-shape, as in the case of FIG.
It is pivotally connected to the operating section 4 via. The rotating side piece 13 protrudes toward the thumb side of the operating hand. That is, the rotating side piece 13 is provided with an inclination parallel to or close to the center line of the pivot shaft 12, and the rotating side piece 13 is provided on the eyepiece 10 side as shown in FIG. That is, when the operating portion 4 is rotated away from the gripping portion, the operating portion 4 approaches a plane that is perpendicular to the center line of the pivot shaft 12 and passes through the longitudinal axis direction l of the operating portion 4.

されている。 Further, an operation knob 14 is provided on the rotation side piece 13.
is attached so as to be movable along its longitudinal direction. That is, a recess 15 is formed on the surface of the rotating side piece 13 along its longitudinal direction, and the protrusion 16 provided on the operation knob 14 side is tightly fitted into and engaged with the recess 15. It's becoming like that. In addition, engagement grooves 17, 17 are formed in the left and right side walls of the recess 15 as shown in FIG. The locking protrusions 18, 18 are fitted and locked. This prevents the operating knob 14 from coming off the recess 15. That is, the protrusion 16 is engaged with the recess 15 so as not to come off, and supports the operation knob 14 so as to be movable in the longitudinal direction of the rotating piece 13. Further, the proximal end portion of the recess 15 is open, and when the protrusion 16 of the operation knob 14 is positioned in the opening 19, the recess 15 is opened.
It can be removed from the Further, this opening 19 is normally closed by fitting a lid 20 as shown in FIGS. 4 and 6. The lid body 20 is pivoted to the rotating side piece 13 via a hinge 21, so that it can be opened and closed. Note that a groove for preventing slipping is formed on the finger contact surface 22 of the operation knob 14.

ままで操作できる。 By the way, in this operation, the thumb can be operated while remaining in a substantially straight state. That is, as shown in FIG. 8, when the operating lever 11 is on the eyepiece 10 side, the operating knob 14 is located on the tip side of the operating lever 11, and as the operating lever 11 is rotated from that position. The operating knob 14 then moves toward the proximal end of the operating lever 11 along the longitudinal direction of the rotating piece 13. In other words, there is no need to bend or straighten the first joint of the thumb, and the thumb can be operated in an almost straight position.

されている。 9 and 10 show a second embodiment of the present invention. That is, in this embodiment, a through-hole 23 is provided in the operating knob 14, and the member of the operating lever 11 is inserted into the through-hole 23 and is movably attached. Further, a locking member 24 made of an elastic material is detachably attached to the tip of the operating lever 11, and an annular protrusion 25 is provided at the base end portion of the rotating piece 13 of the operating lever 11. The operating knob 14 can be moved within the range between the locking member 24 and the protrusion 25. Note that the locking member 24 is connected to the operating lever 1.
1, and a locking pawl 26 provided thereon fits and locks into a groove 27 provided on the operating lever 11 side, and is detachably attached. That is, by removing this locking member 24, the operation knob 14 can also be removed, and can also be attached from there. In addition, the above operation knob 1
A large number of grooves are formed on the finger contact surface 22 of No. 4 for anti-slip purposes.
しかして、この実施例の操作ノブ１４も上記実
施例と同様に使用する。 Therefore, the operation knob 14 of this embodiment is also used in the same manner as in the above embodiment.
