【考案の詳細な説明】
本考案は体内観察特に気管支観察等に用いるファイバー
スコープの改良に関する。[Detailed Description of the Invention] The present invention relates to an improvement of a fiberscope used for in-vivo observation, particularly for bronchial observation.
この種ファイバースコープは可撓管を口中等から気管支
等の被検体内部に向けて挿入し、手許の操作部本体に設
けた操作ノブ或いはレバー等を操作しながら、可撓管先
端の彎曲部を振らせて目的の被検部への侵入を行うよう
に操作され、且つ被検部での組織採集等に際して該彎曲
部を微妙に移動させながらの作業がなされる。In this type of fiberscope, a flexible tube is inserted into the subject's body such as the bronchus through the mouth, etc., and the curved part at the tip of the flexible tube is inserted while operating the operating knob or lever provided on the main body of the operating section at hand. It is operated so that it can be swung to penetrate into the target area to be examined, and the curved part is delicately moved when collecting tissue from the area to be examined.
従って、この作業時における彎曲部の操作性が非常に重
要視されると共に、術者が出来るだけ容易な操作姿勢で
もってその技術を充分に発揮出来ることが強く望まれる
。Therefore, great importance is placed on the operability of the curved portion during this operation, and it is strongly desired that the operator be able to fully demonstrate his or her skills in an operating posture that is as easy as possible.
そこで、本考案はこのような操作性の向上を重視して改
良された機構に特徴を有するものである。Therefore, the present invention is characterized by an improved mechanism with emphasis on improving such operability.
以下図示の実施例を参照して本考案スコープの特徴とす

る。The features of the scope of the present invention will be explained in detail below with reference to the embodiment shown in the drawings. Fig. 1 is a perspective view showing an embodiment of the scope of the present invention. It consists of a tube 2 and a hand operation section main body 3, and the main body 3 is provided with an observation eyepiece 4, an operation knob 5, etc., and the visible tube 2, which houses an optical fiber, a forceps insertion tube, etc., has the curved section. 1 and the operating knob 5 are passed through.
そして、このワイヤー６は図上垂直方向の面で操作され

変換機構部となしである。This wire 6 is wound around a pulley (not shown) that is integrated with the operating knob 5 that is operated in the vertical plane in the figure, and both ends are attached to both edges of the tip of the curved part 1 in the horizontal plane in the figure. Fixed, wire guide pin 7.7 and curved base 1
This wire 6 is connected to a quarter plate and is connected to the converting mechanism part of the operating surface.

するラック１０．１０に夫々取り付けである。FIG. 2 is a perspective view showing the main parts of another embodiment of the scope of the present invention, which is fixed in the operating section main body 3 as a mechanism for converting the operating surface between the connection between the operating knob 5 and the curved tip section 1. Both ends of the wire 6 pulled out from the small hole of the wire guide plate 8 are respectively attached to racks 10 and 10 that mesh with the pinion 9 integrated with the operation knob 5 in a facing state.
このような構成よりなる本考案スコープはその操作上極
めて顕著な効果を発揮する。The scope of the present invention having such a configuration exhibits extremely significant operational effects.
即ち、従来のこの種ファイバースコープは第３図に示す
如く操作ノブ５の操作面（図上垂直面）と同じ向きの面
で先端彎曲部１が俯仰動するような構成であるために、
これを用いて気管支内を観察する場合に被検者を仰姿勢
で寝かせた状態で頭部側から術者が操作ノブ５を回動操
作するので、術者側から左右に広がる気管支の分岐への
可撓管挿入作業はスコープを捩じるか又は術者自身の体
を捩じりながら操作しなければならなかった。That is, as shown in FIG. 3, the conventional fiberscope of this type has a configuration in which the curved tip portion 1 moves up and down in a plane that is in the same direction as the operation surface (vertical plane in the figure) of the operation knob 5.
When using this to observe the inside of the bronchus, the operator rotates the operating knob 5 from the head side while the subject is lying in a supine position. In order to insert the flexible tube, the operator had to twist the scope or twist the operator's own body.
その結果、スコープを捩じることにより、操作ノブの位
置が定まらず、そのために、操作性が鈍り、また方向性
を見失う恐れがある。As a result, by twisting the scope, the position of the operating knob cannot be determined, resulting in poor operability and a risk of losing direction.
そして、術者の体を捩じることにより疲労し易い。Also, twisting the user's body tends to cause fatigue.
又、生検鉗子あるいはブラシ等を使用しての目的部位で

捩じった状態で行うことは極めて不具合である。In addition, when performing tasks such as tissue collection through delicate manipulations at the target site using biopsy forceps or brushes, controlling the injection of contrast media, and spraying anesthetics, the surgeon's body must be twisted. It is extremely inconvenient to do so.
これに対して、本考案スコープでは操作ノブ５を術者が
操作位置から前後方向（垂直操作面）に回動操作するこ

で、この彎曲部１の動きが操作部本体３に対して人体構
造に添った左右彎曲方式となるので、スコープの捩れも
最少限ですみ左右の気管支へのスコープ挿入が極めて容
易に出来る。In contrast, in the scope of the present invention, the operator rotates the operating knob 5 from the operating position in the front-rear direction (vertical operating surface), thereby twisting the wire 6 (as shown in the first figure) or rotating the pinion-rack mechanism (as shown in the second figure). As the tip curved portion moves in the left-right direction (horizontal operation surface) via the actuation surface conversion mechanism (as shown in the figure), the movement of this curved portion 1 is caused by a left-right bending method that conforms to the human body structure with respect to the operation portion main body 3. Therefore, the twisting of the scope is kept to a minimum and the scope can be inserted into the left and right bronchi extremely easily.
そして、この操作によれば、操作ノブ５の位置とその操

著な効果を発揮するものである。According to this operation, the direction of curvature of the curved tip portion 1 is always maintained under a constant condition with respect to the position of the operation knob 5 and the direction of operation thereof, and the direction of curvature of the curved tip portion 1 is always maintained under a constant condition, and the direction of curvature of the tip curved portion 1 can be visually confirmed as the curved portion 1 moves. Since the field of view can be taken in a direction that intuitively matches the direction of operation, the scope is easy to orient when inserting the scope while looking at the endoscope, and there is less chance of misidentification of the observation area. It exhibits extremely remarkable effects when put to practical use.
尚、本考案スコープにおける作動面の変換機構部として
は図示の実施例の他従来知られた各種機構を採用して構
成することが出来る。In addition to the illustrated embodiment, various conventionally known mechanisms can be used as the operating surface conversion mechanism in the scope of the present invention.
