Abstract

<P>PROBLEM TO BE SOLVED: To provide a production method for a washing brush for an endoscope in which filth scraped off by a brush bristle is accumulated in a hair end portion and is raked out when hair ends move while they are rubbed against a wall for brushing in order to wash by brushing the inside of a treatment instrument receiving channel of an endoscope, or the like and a high cleaning effect can be obtained. <P>SOLUTION: The hair ends are formed more thickly than the stem portions of the brush bristles 1 by cooling and hardening as they are after bringing the hair ends 1a of the brush bristles 1 into contact with a heated member 10 or an ultrasonic vibrating member to melt them after putting a mass of the brush bristles 1 between two twisted hard wires 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

この発明は、内視鏡の処置具挿通チャンネル内等をブラッシング洗浄するために用いられる内視鏡用洗浄ブラシの製造方法に関する。   The present invention relates to an endoscope cleaning brush manufacturing method used for brushing and cleaning the inside of a treatment instrument insertion channel of an endoscope.

内視鏡用洗浄ブラシは一般に、撚り合わされた二本の硬質ワイヤの間に多数のブラシ毛を挟み込んだ構成になっており（例えば、特許文献１）、そのような内視鏡用洗浄ブラシを製造する際には、ブラシ毛の毛先を揃えるために、二本の硬質ワイヤの間に挟み込まれた状態のブラシ毛の毛先をカッター等で切り揃えている。
特開平１１−１６９３３４号公報 Endoscope cleaning brushes generally have a structure in which a large number of brush hairs are sandwiched between two twisted hard wires (for example, Patent Document 1). When manufacturing, in order to align the bristles, the ends of the bristles that are sandwiched between the two hard wires are trimmed with a cutter or the like.
JP-A-11-169334

しかし、そのようにして切り揃えられたブラシ毛の毛先は、軸線方向に対して垂直に切られるか斜めに切り削がれた状態になるので、図７に例示されるように、内視鏡のブラッシング対象壁５０に擦り付けられながら移動する際に、ブラシ毛１によって掻き落とされた汚物１００が毛先１ａの周囲から漏れ出てブラッシング対象壁５０に付着したままになり、十分な洗浄効果を得ることができない場合がある。   However, since the bristles of the bristles thus trimmed are cut perpendicularly to the axial direction or cut obliquely, as shown in FIG. When moving while being rubbed against the brushing target wall 50 of the mirror, the filth 100 scraped off by the brush bristles 1 leaks from the periphery of the hair tip 1a and remains attached to the brushing target wall 50, so that a sufficient cleaning effect is obtained. You may not be able to get

そこで本発明は、毛先がブラッシング対象壁に擦り付けられながら移動する際に、ブラシ毛によって掻き落とされた汚物が毛先部分に溜められて、高い洗浄効果を得ることができる内視鏡用洗浄ブラシの製造方法を提供することを目的とする。   Therefore, according to the present invention, when the hair tip moves while being rubbed against the wall to be brushed, the filth scraped off by the brush hair is collected in the hair tip portion, and a high cleaning effect can be obtained. It aims at providing the manufacturing method of a brush.

上記の目的を達成するため、本発明の内視鏡用洗浄ブラシの製造方法は、撚り合わされた二本の硬質ワイヤの間に多数のブラシ毛を挟み込んだ後、ブラシ毛の毛先を、加熱された部材又は超音波振動部材に接触させて溶かした後そのまま冷却硬化させることにより、ブラシ毛の茎部分より太く成形したものである。   In order to achieve the above object, the method for manufacturing an endoscope cleaning brush according to the present invention includes a method in which a plurality of brush hairs are sandwiched between two twisted hard wires, and then the brush hair ends are heated. It is formed to be thicker than the stem portion of the brush hair by bringing it into contact with the formed member or ultrasonic vibration member and dissolving it, followed by cooling and hardening as it is.

なお、ブラシ毛の毛先が略球状に成形されてもよく、ブラシ毛の素材繊維として、予め軸線方向に伸ばした合成樹脂材が用いられると、ブラシ毛の毛先が太く形成され易い。
また、加熱された部材又は超音波振動部材がブラシ毛を囲む円筒状に形成されていると、熱成形の工程が効率化される。 Note that the tip of the brush hair may be formed in a substantially spherical shape, and if the synthetic resin material previously stretched in the axial direction is used as the material fiber of the brush hair, the tip of the brush hair is easily formed thick.
In addition, when the heated member or the ultrasonic vibration member is formed in a cylindrical shape surrounding the bristles, the thermoforming process becomes efficient.

本発明によれば、ブラシ毛の毛先を、加熱された部材又は超音波振動部材に接触させて溶かした後そのまま冷却硬化させることによりブラシ毛の茎部分より太く成形したので、毛先がブラッシング対象壁に擦り付けられながら移動する際に、ブラシ毛によって掻き落とされた汚物が毛先部分に溜められて掻き出され、高い洗浄効果を得ることができる。   According to the present invention, the bristles of the bristles are made thicker than the stem portions of the bristles by contacting the heated bristles with the heated member or the ultrasonic vibration member, and then cooling and hardening them as they are, so that the bristles are brushed. When moving while being rubbed against the target wall, the filth scraped off by the brush hair is collected and scraped off at the hair tip portion, and a high cleaning effect can be obtained.

二本の硬質ワイヤの間に挟み込まれた状態の多数のブラシ毛の毛先を、円筒形状の加熱部材に接触させて溶かした後そのまま冷却硬化させることにより、ブラシ毛の茎部分より太く成形する。   The bristles of a large number of brush bristles sandwiched between two hard wires are melted in contact with a cylindrical heating member, and then cooled and hardened as they are, so that they are thicker than the stem portion of the bristles. .

図面を参照して本発明の実施例を説明する。
図２は内視鏡用洗浄ブラシの全体構成を示しており、多数のブラシ毛１が放射状に取り付けられたブラシ軸２が、内視鏡の処置具挿通チャンネル等に挿脱される可撓軸３の先端に取り付けられている。 Embodiments of the present invention will be described with reference to the drawings.
FIG. 2 shows the overall configuration of the endoscope cleaning brush. A flexible shaft through which a brush shaft 2 having a large number of brush hairs 1 attached radially is inserted into and removed from a treatment instrument insertion channel of the endoscope. 3 is attached to the tip.

ブラシ軸２は、製造工程を示す図３に示されるように、二本のステンレス鋼線等のような硬質ワイヤを撚り合わせたものであり、その撚り合わせ部分に、例えばポリアミド樹脂等のような軟質の合成樹脂材からなる多数の繊維状のブラシ毛１が挟み込まれて固定されている。   As shown in FIG. 3 showing the manufacturing process, the brush shaft 2 is formed by twisting hard wires such as two stainless steel wires, and the twisted portion is made of, for example, polyamide resin or the like. A large number of fibrous brush hairs 1 made of a soft synthetic resin material are sandwiched and fixed.

なお、ブラシ毛１の素材中にガラス繊維等を混入させてもよい。ただし、素材となる合成樹脂材は熱可塑性であることが望ましい。また、ブラシ軸２をそのまま手元側に延長して可撓軸３として用いてもよい。   In addition, you may mix glass fiber etc. in the raw material of the bristle 1. However, it is desirable that the synthetic resin material used as a material is thermoplastic. Further, the brush shaft 2 may be extended as it is to the hand side and used as the flexible shaft 3.

各ブラシ毛１は、予め一定の長さに切断された素材繊維の中心部分をブラシ軸２の二本の硬質ワイヤの間にきつく挟み付けて固定したものであり、その毛先１ａの輪郭はほぼ円柱状を呈している。   Each bristle 1 is obtained by fixing a central portion of a raw material fiber that has been cut to a predetermined length tightly between two hard wires of the brush shaft 2, and the outline of the bristle tip 1a is as follows. It is almost cylindrical.

この製造工程においては、そのようにしてブラシ軸２に固定されたブラシ毛１の毛先１ａを、内蔵ヒーター１１により加熱された加熱部材１０に接触させて溶かし、各ブラシ毛１の毛先１ａを揃える。   In this manufacturing process, the bristles 1 a of the bristles 1 fixed to the brush shaft 2 in this way are brought into contact with the heating member 10 heated by the built-in heater 11 and melted, and the bristles 1 a of each bristles 1 Align.

すると、ブラシ毛１の毛先１ａが一旦溶けてから加熱部材１０の離脱によりそのまま冷却硬化する際に、自己の表面張力によって図４に示されるような略球状、又は図５に示されるような先太形状になり、いずれの場合でも毛先１ａがブラシ毛１の茎部より太く形成される。なお、ブラシ毛１の素材繊維として予め軸線方向に伸ばした合成樹脂材を用いると、毛先１ａが熱成形の際に太く仕上がり易い。   Then, when the bristles 1a of the bristles 1 are once melted and then cooled and hardened as they are by detachment of the heating member 10, they are substantially spherical as shown in FIG. 4 due to their own surface tension, or as shown in FIG. In any case, the hair tip 1 a is formed thicker than the stem portion of the brush hair 1. In addition, if the synthetic resin material previously extended in the axial direction is used as the material fiber of the brush hair 1, the hair tip 1a is likely to be thickly finished during thermoforming.

このように構成された内視鏡用洗浄ブラシを内視鏡の処置具挿通チャンネル内のブラッシング洗浄等に用いると、図１に示されるように、ブラシ毛１の毛先１ａが内視鏡のブラッシング対象壁５０に擦り付けられながら移動する際に、ブラシ毛１によって掻き落とされた汚物１００が毛先１ａ部分に溜められて掻き出され、高い洗浄効果を得ることができる。   When the cleaning brush for an endoscope configured in this way is used for brushing cleaning or the like in a treatment instrument insertion channel of an endoscope, as shown in FIG. When moving while being rubbed against the wall 50 to be brushed, the filth 100 scraped off by the brush bristles 1 is collected and scraped off at the hair tips 1a, and a high cleaning effect can be obtained.

なお、加熱部材１０を、図６に示されるようにブラシ毛１を囲む円筒状に形成すれば、ブラシ毛１を加熱部材１０内に通すだけで全体のブラシ毛１の毛先１ａを容易に熱成形することができ、作業が効率化される。また、加熱部材１０に代えて超音波振動部材等を用いてブラシ毛１の毛先１ａを溶かすようにしてもよい。   If the heating member 10 is formed in a cylindrical shape surrounding the bristles 1 as shown in FIG. 6, the bristles 1 a of the entire bristles 1 can be easily obtained simply by passing the bristles 1 through the heating members 10. Thermoforming can be performed, and the operation is made efficient. In addition, the bristles 1 a of the bristles 1 may be melted by using an ultrasonic vibration member or the like instead of the heating member 10.
