Description

[Detailed description of the invention] 4+'l operations such as air supply and water supply are clearly displayed on the operating section.
The present invention relates to an endoscope equipped with a switching operation device section that has a hook.

The operating section of the Ben-Sung endoscopy had a grip that the operator could hold with one hand, and an i on the operating section body located at F/J of the grip.
There is an eyepiece section provided at the t-end. Further, on the side surface of the main body of the operating section located between the eyepiece section and the grip section, a number of operation buttons for controlling air supply, water supply, and suction operations are installed. Furthermore, an angle knob is provided on the side surface of the operating section main body for operating a bending operation mechanism consisting of a googly or the like installed within the operating section main body.

By the way, the central axes of each of the above-mentioned operation buttons are perpendicular to the gripping central axis of the gripping part, or are they in the same direction as the actual
As shown in Japanese Patent No. 163403, it is inclined toward the gripping portion. For this reason, when gripping the grip part with the ring finger and little finger of one hand and operating the operation buttons with the index and middle fingers respectively,
When the layer phase is applied to the optimum position of the angle knob described in 1, the bending direction of each joint of the index finger and middle finger is different from the direction of the central axis of the pressing g movement of the operation button due to their relative positional relationship. It was difficult to operate. In addition, the angle horn is often held temporarily fixed by the ring finger while gripping it while rotating 1ψ, but - ゛, during normal angle operation, the hkζ angle angle! ft.
However, I could not resolve this and the operation was incorrect.

9) Therefore, the bending operation mechanism 4 installed inside the operation unit main body:
(It was decided to install it closer to the S side, so the operation part 4.44 extended upwards and the operation part became a large piece.)

This book was created with a focus on self-aggression, and the purpose of f is to control the direction of operation t(, as well as the direction of VC(傛・0). The goal is to create an endoscope that can be used to improve

[An embodiment of the present invention will be described based on the drawings. In the figure, 1 indicates an endoscope, which is composed of an insertion section 2 and an operating section 3 connected to the proximal end of the endoscope. The operating section 3 has various structures incorporated in the operating section main body 4 as will be described later. That is, the main body 4 of the operating section 5 is made of glass and has a relatively elongated shape as a whole, and each side surface on the rear left side of the main body 4 is formed into a substantially flat surface. First, a stopper part 5 is connected to one end of the operating part main body 4.

The base end of the L insertion part 20 is connected to the L insertion part 20, and the eyepiece part 6 is provided at the other end of the operating part 41 body 4. Furthermore, 5 operation unit main body 4
The circumferential surface of the middle part is the operator's 3- (left hand in this example).
A grip part 7 that can be gripped using the miniaturization 3
Tonatsu-C potato. It's fangs.

The proximal end 8 of the operation unit main body 4, which is located closer to the eyepiece 6 than the grip 7, is provided with a platform 9 by protruding the front h'' side part. 7 and grip part 7
A rising wall 11 for cJ=C is formed by the step formed between. Eyepiece part 6 on the surface of F blending part 9
The side is downward, and the grip portion 7 side is tilted so that it protrudes.

And, on this stand, ;, 9 -, (plane Ku air/water supply operation button 12 and suction operation button 13 are arranged side by side along the longitudinal axis direction of the operation section main body 4. Button 12 Fi Internal View! #1 (1 (l1g) Air and water supply operation button 12 which is used to selectively perform air and water supply actions by switching the configured Mc path for air and water supply. It operates a valve device consisting of a cylinder and a piston, and when the leak hole opening in the finger rest 14 is closed by placing a viper on the finger rest 14, air is supplied. Water is supplied by pressing and moving -I+.Also, the suction operation button 13 similarly operates a valve device consisting of a cylinder and a piston; By applying the belly of the device and moving it, suction can be performed.

In other words, each of the operation buttons 12, j, and Sr is pressed with a fingertip.

Further, an angle operation knob f11, which is a rotating shaft 16, is attached to the right side surface of the ordinary side end 8θ). By rotating the drum of the angle operating machine groove installed in the main body 4 of the angle operating part f17Vi, and moving the pair of operating wires inserted into the insertion part 3 forward and backward,
The direction of curvature of the tip of the 4-4 portion 3 is changed.

In addition, at the corner between the left side surface i1 of the hand side end portion 8 and the unloading side surface portion, there is a folding stop portion 18 that extends in an oblique direction.
The light guide cable 19 is connected to the light guide cable 171 at the end of the operation section main body 4 on the insertion section 2 side.
A protruding part 21 is integrally formed on the side [ifI, and the tip of this protruding part 21 is used to hold a tool such as forceps internally.
A treatment instrument opening 22 is formed for inserting and removing the treatment instrument into and out of the insertion channel. Note that the gripping portion 1 is located between the rising wall 11 and the protruding portion 21.

By the way, the optical axis 01Fi of the eyepiece section 6 intersects the grip central axis 0 of the grip section 7, and the grip 1'', a-axis O!
The angle θ formed by each axis 01eUx of the axis 01eUx is tilted toward the opposite side of the platform 9.

The analogy is 12 degrees. In other words, the eyepiece 6r
t The operator grasps the grip part 7 of the main body 4 of the body 4 and holds it while operating the operation knob 17 of each operation 1dJ12, 13f'. It is easy to see the temperature at °C.

In addition, the center axis os of the pushing movement of each operation t41 r 2.7 s in Section 111 is parallel to -J as mentioned above, but this pushing movement; It intersects with the central axis O3 or passes near it. Furthermore, each pushing movement center axis 0
．． ．． 0. The angle U (measured from the grip part 1 side) that the grip part 1 makes with respect to the central grip axis O2 is an angle exceeding 90 degrees, that is, an obtuse angle.

This q+tta=Vi-usually 100@~110a is optimal. In this example, the angle is also an appropriate 102°.
(Note that all directions of the rising shaft 11 are along the direction of the center axis Us = Oa of the pushing movement of the peak.) [It is formed flat.

Therefore, when using the oriented endoscope 1, grip the grip part 1 with the ring finger and little finger of one hand as shown in Fig. 2, and
The front side part where each operation button 12.13 is located is located at the farthest position from the operator. Then, if necessary, place the pad of the tip of your thumb on the operation knob 77K and rotate it.

The fingertips of the index and middle fingers are placed on the finger rests 14.15 of the operation buttons 12 and 13, respectively, and the joints are bent to selectively press down. In addition, at this time, the ring finger and the little finger are in contact with each other side by side, while the 4dl1 curve of the ring finger is positioned in contact with the rising wall 11, and at the same time, the movement of moving toward the eyepiece 6 side is stopped during each operation, allowing stable operation. can be carried out.

By the way, in order to make the operation unit 3 small and light, it is better to position the operation mechanism structure including the operation buttons 12 and 13 and the operation knob I7 closer to each other, so that the hand side end 8 is closer to the eyepiece 6.
Since it is not formed to extend to the side, it can be made smaller and lighter. On the other hand, when operating the operation knob 17 with the thumb of the operator's left hand, it is best to place the abdomen of the fingertip of the thumb on the tip of the operation knob 17.
The easiest to operate. Furthermore, each of the operation buttons 12 and IB can be operated most reliably and at 8 kjr by pressing with the abdomen of the fingertip of the index or middle finger of the operator's left hand. It is common to press 4 and ψ of each operation button 12°IB using only the index finger, but it is also known to perform the operations individually using the index and middle fingers (see Figure 2). In this method, as described above, the side surface of the ring finger is placed on the rising wall II and the grip portion 7 is gripped with the ring finger and little finger.
When the thumb is applied to the operating knob 17 at the appropriate position tX, the bending direction 1 of each joint of the middle finger and the middle finger is determined by the relative positional relationship of the imitation knob 77, each operating button 12, 1B, and the grip portion 7.
As shown in the tlZ diagram, the grip center axis 0 of the grip part 7 is χ1
Then, the angle will exceed 9 (F. Then, according to this, - Ch. each operation button 12° IB push movement axis Oj, Oa
Because the direction is set.

It is located in @ho, which is easy to operate.

Here, we will discuss in more detail the relative positional relationship of each part of the E period. In the operation part 3 of endoscope m7, eel is also frequently detected,
An important operation is the bending operation using the operation knob 17 mentioned above. The operation knob 17#-i, which is operated with the thumb of the left hand, is rotated by pulling down or pushing up the thumb. While the operating knob 17 may be held with the tip of the finger (middle finger or ring finger) that is hooked on the knob 11, the operation knob 17 may be held in a position where this finger (middle finger or ring finger) does not interfere with the rotation of the operating knob 17. knob 1
It is also necessary that there be 7. Therefore, standing wall II
The relative positional relationship between the finger and the operation knob 11 is determined so that both operations can be satisfied with a slight movement of the finger. Also,
Another reason is that when the operating knob 12 is located toward one side of the eyepiece 6, the operating section main body 4 extends far toward the eyepiece 6 due to the structure of the bending operation mechanism within the operating section main body 4, and the operation can be performed accordingly. There are circumstances in which Department 3 is becoming larger and more overlapping. On the other hand, the relationship between the air and water supply operation button I2 and the rising wall 11 is as follows.
It is easier to operate it if the finger on I and the finger on the air/water supply operation button 12 are not spread apart.

For this reason, it is better to have both fingers as close as possible. Therefore, the interval is set so that the fingers of both the ff1k wall 1 and the air/water supply operation button 12Fi touch. Further, the outer diameter of the operating knob 11 is determined by the relationship between the power factor that applies the curvature and the rotation angle of the operating knob 17, and the position of the co-rotating shaft 16 of the operating knob 17 is determined accordingly.

In addition, each operation button 12.13 can be pressed using two fingers, the first finger and the middle finger.
When operating, it is natural that the two finger joints are almost parallel in the direction of bending, and for this reason, the center axis of each pushing movement O
s, 04H parallel.

In addition, this folding part 18 and the light guide Kemel 1
If the operator is holding the operation part 3 lightly, the operator's hand will hit the operator's hand and prevent the operator from slipping off. In order to utilize this function, it is better not to be too far from N Samurai Department 1. In the present invention, there is no need to extend the operation section main body 4 toward the eyepiece section 6, so it can be moved closer to the eyepiece section 6.

[As explained above, the operation part 44 has a swinging end that is grasped using at least the ring finger and little finger of one hand, and is located next to the seven holding hands. At least two operation buttons are provided, and the depression movement of each operation button in L is substantially parallel to the IH center + r' + rx On the other hand, the corner angle extending N1 from the grip side is inclined to form an obtuse angle. Therefore, it is easy to individually operate each corresponding operation button with a plurality of fingers of the hand grasping the end of the plum, and the operation knob can be reliably operated with the sixth finger or ring finger of the same hand. Furthermore, since the rotation axis (91) of the operation knob can be brought closer to the grip part, the internal mechanism operated by the operation knob Vζ can be installed in the grip part 41111. Therefore, the operation part The main body is not extended and can be made lighter and smaller.
