多大な角度範囲にわたつて湾曲させることがあ
る。 When observing or treating the inside of a body cavity with an endoscope, it is necessary to bend the angle part of the end using the angle dial on the handle in order to make the observation window or the like face the affected area. The bending operation involves bending the bendable angle portion between the rigid distal end portion having the observation window etc. and the flexible tube portion having a built-in spiral etc. using the angle dial via the operation wire. In this bending operation, it may be bent over a wide range of angles, for example, 180 degrees upward in the axial direction and 90 degrees downward.

がよつて体腔内への挿入や操作に支障をきたした
り、さらにこのアングル部がよく曲らないという
問題もある。 In the above-described bending operation, since the maximum bending angle is different in the two directions, up and down, the reaction force of the angle portion is different in both directions, and the force required for the operation becomes non-uniform depending on the bending direction. Further, there are also problems in that the covering of the angle part is wrinkled, which hinders insertion into a body cavity and operation, and that the angle part does not bend well.
本考案は、上記した諸問題を解決するためにな
されたものであり、その第１の目的は、湾曲操作
に必要な力を上下２方向に均一化することにあ
る。 The present invention was made to solve the above-mentioned problems, and its first purpose is to equalize the force required for the bending operation in two directions, up and down.
第２の目的は、アングル部を湾曲させたときに
過大なしわが発生しないようにすることにある。 The second purpose is to prevent excessive wrinkles from occurring when the angle portion is curved.
第３の目的は、アングル部の全体がよく湾曲す
るようにすることにある。 The third purpose is to ensure that the entire angle portion is well curved.
上記した諸目的を達成するため、本考案は、自

させたことを特徴とする。 In order to achieve the above-mentioned objects, the present invention is characterized in that an elastic tube, which is naturally curved in a specific direction, is tightly coated on the angle portion and curved in a specific direction in advance.
以下に図面を用いて本考案の一実施例を説明す
る。 An embodiment of the present invention will be described below with reference to the drawings.

す。 FIG. 1 is a schematic cross-sectional view, and in the drawing, the light guide for illumination following the light source 2, 3 an image guide for guiding the image of the object, 4 an angle dial provided on the handle 5, and 6 this light guide. The operating wire that is pulled and operated by the angle dial 4 is shown.

可能なアングル部１０に、第２図に示す如くあら
かじめ特定方向に湾曲させた弾性管体１１を密着
被覆してある。これによつて上記アングル部１０
も湾曲することになる。 In the endoscope described above, a bendable angle portion 10 between a rigid tip portion 8 having an observation window 7 etc. and a flexible tube portion 9 such as a spiral is bent in a specific direction in advance as shown in FIG. The elastic tubular body 11 is tightly covered. As a result, the angle portion 10
will also be curved.
例えば第３図に拡大して示す如く、内視鏡の最
大湾曲角度が軸方向上方に180゜、下方向に90゜で

ングル部１０は湾曲し、曲折の際に所定の湾曲操
作が容易となる。 For example, as shown enlarged in Fig. 3, when the maximum bending angle of the endoscope is 180° upward in the axial direction and 90° downward, the maximum bending angle of the endoscope is approximately 45°, which is the neutral point of the bending angle in the two vertical directions. By closely covering the angle portion 10 with the elastic tubular body 11 bent in the direction, the angle portion 10 is curved in advance, and a predetermined bending operation is facilitated at the time of bending.
上記した本考案にかかる内視鏡によると、あら
かじめ特定方向に湾曲させた弾性管体をアングル
部に密着被覆させたことにより、例えば上下方向
の最大湾曲角度の中立点近傍から湾曲操作を容易
に行なうことができることになり、湾曲操作に必
要な力を上下方向に略均一化することができる。 According to the above-mentioned endoscope according to the present invention, by closely covering the angle portion with the elastic tube that has been curved in a specific direction in advance, the bending operation can be easily performed, for example, from near the neutral point of the maximum bending angle in the vertical direction. This allows the force required for the bending operation to be made substantially uniform in the vertical direction.
また、アングル部に過大なしわを発生させるこ
とがなくなり、アングル部を曲がり易くすること
ができるという有意義な効果を発揮することがで
きるものである。 Further, the angle portion is prevented from being excessively wrinkled, and the angle portion can be bent easily, which is a significant effect.
