本発明はたとえは内視鏡の挿入部に用いる可撓管に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a flexible tube used, for example, in an insertion section of an endoscope.
一般に、内視鏡の挿入部は長尺な可撓管からな９、この

押出し成形してなるものであり、その外皮とグレードと
を接合させる。Generally, the insertion section of an endoscope is made of a long flexible tube 9, and a tip member is connected to the tip of the flexible tube through a curved tube or in contact with it. By the way, the above-mentioned flexible tube is made by fitting a blade made of metal M on the outer periphery of a flex made of a spirally wound gold band plate, and covering the outer surface of the flexible tube with a skin. The outer skin is formed by applying an adhesive to the outer surface of the blade and extruding the outer skin material into a tube shape in the shape of a tube bottom, and the outer skin and the grade are bonded together.
しかし、合成樹脂製の外皮はグレードの単純な外表面に
単に接着するだけであるため、接着結合力が弱く、外皮
とグレードとの間に＠離が生じ易い。そして、剥離が生
じると、可撓管が座屈して使用不可能になることがあっ
た。However, since the synthetic resin outer skin simply adheres to the outer surface of the grade, the adhesive bonding force is weak and separation easily occurs between the outer skin and the grade. When peeling occurs, the flexible tube may buckle and become unusable.
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、比較的簡単な構成により外皮とプレー
Ｖとの接着剤による結合力を増大した可撓管を提供する
ことにある。The present invention has been made in view of the above circumstances, and its purpose is to provide a flexible tube with a relatively simple structure that increases the bonding force between the outer skin and the play V due to the adhesive. .
本発明は、サンドブラストなどによりブレードの外表面
を荒し、ブレードに対する外皮の接着による結合力を高
めた可撓管である。The present invention is a flexible tube in which the outer surface of the blade is roughened by sandblasting or the like to increase the bonding strength due to the adhesion of the outer skin to the blade.
以下、本発明の実施例を図面にもとづいて説明する。 Embodiments of the present invention will be described below based on the drawings.

端には挿入部の先端部材が連結される。FIG. 1 shows a part of the insertion section of an endoscope. In the figure, 1 is a flexible tube, and a curved tube (not shown) can be connected to the tip of the flexible tube 1 via an inner mouthpiece 2. It will be done. Further, the tip member of the insertion section is connected to the tip of the curved tube.
上記可撓管１は帯状の金属板をら旋状に巻回してなるフ
レックス３の外周にブレード〔網管〕４を被嵌し、石ら
にグレード４の外周を樹脂製の外皮５で被覆してなる。The above-mentioned flexible tube 1 has a blade (mesh tube) 4 fitted around the outer periphery of a flex 3 made by winding a band-shaped metal plate in a spiral shape, and a resin outer skin 5 covering the outer periphery of a grade 4 stone. It becomes.

As shown in the figure, it is knitted into a tubular shape.

囲の光面あらさが望ましい。In addition, the outer peripheral surface of Grade 4 is roughened by, for example, chemical treatments such as Puntoplast or Bead Plast, or chemical treatments such as nitric acid, forming a rough surface that increases the adhesion of the Yi contact agent. It is. In addition, surface roughness roughened by mechanical processing, such as sandblasting, etc., is defined as surface roughness excluding 0.88 in the standard number sequence for the largest island of JIS indication (B 0601-1982), that is, (Go
A surface roughness of ~1.6)S is desirable, and an optical surface roughness in the range of (200 to 1.6)S is desirable.
そして、上記ブレード４の外周に外皮５′を形成する場

に接着剤を塗布し、このあとでたとえばチェーグ成形機
により押出し酸形してグレード４の外周に外皮５を成形
する。グレード４と外皮５とは、接着剤によＶ接着され
、接合される。When forming the outer skin 5' on the outer periphery of the blade 4, an adhesive is first applied to the outer periphery on which the grade 4 rough surface has been formed, and then extrusion and acid molding are performed using, for example, a Chague molding machine. The outer skin 5 is formed around the outer periphery of the grade 4. Grade 4 and outer skin 5 are V-bonded and joined using an adhesive.
しかして、上記＊ａにおいて接着剤を塗布するブレード
４の外周表面は、荒されて粗面を形成しているから、接
着剤との結合力が高まる。Since the outer circumferential surface of the blade 4 on which the adhesive is applied in *a above is roughened to form a rough surface, the bonding force with the adhesive is increased.
このため、接着剤によるグレード４と外皮５との結合力
が強く、剥離を防よする。Therefore, the bonding force between Grade 4 and the outer skin 5 due to the adhesive is strong, and peeling is prevented.
なお、上記実施例ではブレード４を編成したあとで、そ

らず、他の部分まで粗面を形成でれる。In the above embodiment, after the braid 4 is knitted, the outer circumferential surface is roughened to form a rough surface, or the wire 6 before knitting the grade 4 may have a rough surface formed in advance. In this case, a rough surface can be formed not only on the outer peripheral surface of the normal play r4 but also on other parts.

する。As explained above, since at least the outer circumferential surface of the blade of the present invention is roughened, the adhesion of the adhesive to the outer circumferential surface can be increased. For this reason, the adhesive bonding force between the grade and the outer skin by the adhesive becomes strong, and it is possible to prevent the outer skin from peeling off from the grade using the Kinki made wire. It also prevents damage to the flexible tube and improves its durability.
