Description

この発明は可撓性内視鏡の配管接続部に関する。   The present invention relates to a pipe connecting portion of a flexible endoscope.

内視鏡の可撓性挿入部内には、処置具挿通チャンネル用や送気送水用等各種の可撓性チューブが挿通配置されていて、可撓性挿入部の基端に連結された操作部側において可撓性チューブの端部が剛性の管路部材に接続固定されている（例えば、特許文献１）。
特開平７−２３９０１ Various flexible tubes for treatment instrument insertion channels and air / water supply are inserted and arranged in the flexible insertion portion of the endoscope, and the operation portion is connected to the base end of the flexible insertion portion. On the side, the end of the flexible tube is connected and fixed to a rigid duct member (for example, Patent Document 1).
JP 7-23901 A

内視鏡の可撓性挿入部は、体内への挿脱、誘導の際に、単純な進退操作が行われるだけでなく不規則に捩じり運動等が加えられたりループ状に曲げられたりする。それに伴って、可撓性挿入部の内部に挿通配置されている可撓性チューブにも捩じり力が作用する。   The flexible insertion part of the endoscope is not only a simple advance / retreat operation when it is inserted into / removed from / into the body, but is also subject to irregular twisting or bending. To do. Along with this, a torsional force also acts on the flexible tube inserted and arranged inside the flexible insertion portion.

すると、可撓性チューブの中で最も径が大きい処置具挿通チャンネル等には捩じれ力が吸収されることなくそのまま伝わり易く、基端部の接続固定部の近傍で処置具挿通チャンネルが捩じり力により座屈してしまう場合がある。   Then, the treatment instrument insertion channel having the largest diameter among the flexible tubes is easily transmitted without being absorbed by the twisting force, and the treatment instrument insertion channel is twisted in the vicinity of the connection fixing portion of the proximal end portion. It may be buckled by force.

そこで本発明は、可撓性挿入部が捩じられても、その内部に挿通配置されている処置具挿通チャンネル等の可撓性チューブが捩じり力によって座屈しない耐久性の優れた可撓性内視鏡の配管接続部を提供することを目的とする。   Therefore, the present invention provides an excellent durability that allows a flexible tube such as a treatment instrument insertion channel inserted therein to be buckled by a twisting force even when the flexible insertion portion is twisted. It aims at providing the piping connection part of a flexible endoscope.

上記の目的を達成するため、本発明の可撓性内視鏡の配管接続部は、内視鏡の可撓性挿入部内に挿通配置された可撓性チューブの基端部が、可撓性挿入部の基端に連結された操作部側で管路部材に接続された可撓性内視鏡の配管接続部において、可撓性チューブの基端部を、軸線周りに回転自在な回転フリー接続手段により管路部材に接続したものである。   In order to achieve the above-described object, the pipe connection portion of the flexible endoscope of the present invention is such that the base end portion of the flexible tube inserted and arranged in the flexible insertion portion of the endoscope is flexible. In the piping connection part of the flexible endoscope connected to the duct member on the operation part side connected to the base end of the insertion part, the base end part of the flexible tube can be freely rotated around the axis. It is connected to the pipe line member by connecting means.

なお、回転フリー接続手段が、可撓性チューブの基端に固着されて管路部材に対して軸線周りに回転自在に嵌合するチューブ基端口金と、そのチューブ基端口金と管路部材との嵌合部をシールするためのシール部材と、チューブ基端口金を管路部材との嵌合部から軸線方向に移動しないように規制する抜け止め部材とを有していてもよく、その場合、抜け止め部材が管路部材側に対して螺合するナット状の部材であってもよい。   In addition, the rotation free connection means is fixed to the proximal end of the flexible tube and is fitted to the tube member so as to be rotatable about the axis, and the tube proximal end tube and the tube member. A sealing member for sealing the fitting portion of the tube, and a retaining member for restricting the tube base end cap from being moved in the axial direction from the fitting portion with the pipe member. Further, a nut-like member in which the retaining member is screwed to the pipe member side may be used.

また、可撓性チューブが処置具挿通チャンネルであってもよく、その場合に最も大きな効果がある。   Further, the flexible tube may be a treatment instrument insertion channel, and in that case, there is the greatest effect.

本発明によれば、可撓性チューブの基端部を、軸線周りに回転自在な回転フリー接続手段により管路部材に接続したことにより、可撓性挿入部が捩じられてそれと共に内部に挿通配置されている可撓性チューブに大きな捩じり力が作用しても、可撓性チューブが操作部側の基端部において管路部材に対して軸線周りに自由に回転することができるので、可撓性チューブが軸線周りに捩じれて座屈するような現象が発生せず、優れた耐久性を得ることができる。   According to the present invention, the base end portion of the flexible tube is connected to the pipe member by the rotation-free connecting means that is rotatable around the axis, so that the flexible insertion portion is twisted and is inserted into the inside. Even when a large torsional force is applied to the inserted flexible tube, the flexible tube can freely rotate around the axis with respect to the conduit member at the proximal end portion on the operation unit side. Therefore, the phenomenon that the flexible tube is twisted around the axis and buckled does not occur, and excellent durability can be obtained.

内視鏡の可撓性挿入部内に挿通配置された処置具挿通チャンネルの基端部が、可撓性挿入部の基端に連結された操作部側において剛性の配管分岐部材に接続された可撓性内視鏡の配管接続部において、処置具挿通チャンネルの基端部を、軸線周りに回転自在な回転フリー接続手段により配管分岐部材に接続する。   The proximal end portion of the treatment instrument insertion channel inserted and arranged in the flexible insertion portion of the endoscope is connected to a rigid pipe branching member on the operation portion side connected to the proximal end of the flexible insertion portion. In the pipe connection portion of the flexible endoscope, the proximal end portion of the treatment instrument insertion channel is connected to the pipe branching member by rotation-free connection means that is rotatable around the axis.

In FIG. 2, reference numeral 1 denotes an endoscope operation part, 2 a flexible insertion part, 3 a connected flexible tube to which a light guide connector (not shown) is attached at the tip. An air supply operation valve 4 and a suction operation valve 5 are arranged.

６は、可撓性挿入部２内に全長にわたって挿通配置されている太くて厚肉の処置具挿通チャンネル（可撓性チューブ）であり、例えば四フッ化エチレン樹脂チューブ等のような可撓性チューブによって形成されて、処置具挿入口７から差し込まれた処置具（図示せず）を可撓性挿入部２の先端から突出させるためのガイドとして機能する。   Reference numeral 6 denotes a thick and thick treatment instrument insertion channel (flexible tube) that is inserted and disposed in the flexible insertion portion 2 over its entire length. For example, a flexible tube such as a tetrafluoroethylene resin tube or the like is provided. It is formed by a tube and functions as a guide for causing a treatment tool (not shown) inserted from the treatment tool insertion port 7 to protrude from the distal end of the flexible insertion portion 2.

１１〜１６は、内視鏡内に配管されているその他の可撓性チューブであり、１１と１２は、ライトガイドコネクタ側から空気と水が送られてくる給気チューブと給水チューブ、１３と１４は、可撓性挿入部２の先端側に空気と水を送り出すための送気チューブと送水チューブであり、各々の端部が送気送水操作弁４から突設された金属製の接続管１７に接続され、各接続部が接続固着部材１８により固定的に接続されている。   11 to 16 are other flexible tubes piped in the endoscope, and 11 and 12 are an air supply tube and a water supply tube through which air and water are sent from the light guide connector side, Reference numeral 14 denotes an air supply tube and a water supply tube for sending out air and water to the distal end side of the flexible insertion portion 2, and a metal connection pipe in which each end portion protrudes from the air supply / water supply operation valve 4. 17, each connection portion is fixedly connected by a connection fixing member 18.

また、１５はライトガイドコネクタ側から吸引が行われる吸引チューブ、１６は、処置具挿通チャンネル６と連通接続された連通チューブであり、各々の端部が吸引操作弁５から突設された金属製の接続管１７に接続され、その接続部が接続固着部材１８により固定的に接続されている。   Reference numeral 15 denotes a suction tube that performs suction from the light guide connector side. Reference numeral 16 denotes a communication tube that is connected to the treatment instrument insertion channel 6, each of which is made of a metal projecting from the suction operation valve 5. The connection portion is fixedly connected by a connection fixing member 18.

処置具挿通チャンネル６の基端には、操作部１の下端部付近に突出して配置された処置具挿入口７に真っ直ぐに通じる処置具導入路８と連通チューブ１６側への連通路とがＹ字状に形成されたステンレス鋼製の配管分岐部材１９（管路部材）が接続されている。   At the proximal end of the treatment instrument insertion channel 6, there are a treatment instrument introduction path 8 that communicates straightly with the treatment instrument insertion port 7 that protrudes in the vicinity of the lower end of the operation section 1 and a communication path to the communication tube 16 side. A stainless steel pipe branch member 19 (pipe line member) formed in a letter shape is connected.

図１はそのような配管分岐部材１９と処置具挿通チャンネル６との接続部付近を示しており、配管分岐部材１９に対して、連通チューブ１６は配管分岐部材１９から突設された金属製の接続管１９′に例えば接着と糸緊縛（接続固着部材１８）によって固定的に接続されているが、処置具挿通チャンネル６は、回転フリー接続手段２０によって軸線周りに回転自在に接続されている。   FIG. 1 shows the vicinity of a connection portion between such a pipe branching member 19 and the treatment instrument insertion channel 6, and the communication tube 16 is made of a metal projecting from the pipe branching member 19 with respect to the pipe branching member 19. For example, the treatment tube insertion channel 6 is connected to the connection pipe 19 ′ so as to be rotatable about the axis by the rotation-free connection means 20.

この実施例の回転フリー接続手段２０は、処置具挿通チャンネル６の基端に接続固着されて配管分岐部材１９に対し軸線２１ｘ周りに回転自在に嵌合するチューブ基端口金２１と、そのチューブ基端口金２１と配管分岐部材１９との嵌合面をシールするための例えばＯリング等からなるシール部材２２と、チューブ基端口金２１を配管分岐部材１９との嵌合部から軸線方向に移動しないように規制する抜け止め部材２３から成っている。   The rotation-free connecting means 20 of this embodiment includes a tube base end cap 21 that is connected and fixed to the base end of the treatment instrument insertion channel 6 and is fitted to the pipe branching member 19 so as to be rotatable about the axis 21x, and its tube base. The seal member 22 made of, for example, an O-ring for sealing the fitting surface between the end cap 21 and the pipe branching member 19 and the tube base end cap 21 are not moved in the axial direction from the fitting portion with the pipe branching member 19. It consists of the retaining member 23 which regulates like this.

チューブ基端口金２１は、配管分岐部材１９との接続部分より処置具挿通チャンネル６との接続部分側の方が外径が細い段付の円筒状に形成されていて、処置具挿通チャンネル６との接続は例えば接着と糸緊縛により固定的に行われている。   The tube base end cap 21 is formed in a stepped cylindrical shape having a smaller outer diameter on the side of the connection portion with the treatment instrument insertion channel 6 than the connection portion with the pipe branching member 19. These connections are fixedly made, for example, by bonding and thread binding.

そして、配管分岐部材１９側と嵌合するチューブ基端口金２１の太い外径部分の外周部には円周溝が全周にわたって形成されていて、シール部材２２がその円周溝内に装着されている。ただし、その他のシール構造を採用しても差し支えない。   And the circumferential groove is formed in the outer peripheral part of the thick outer diameter part of the tube base end cap 21 fitted to the piping branch member 19 side, and the seal member 22 is mounted in the circumferential groove. ing. However, other seal structures may be adopted.

抜け止め部材２３は、配管分岐部材１９の外周部に形成されている雄ネジと螺合する雌ネジが全長の約半分の部分に形成されたナット状の部材であり、残りの半分の部分は内径がチューブ基端口金２１の最大外径よりやや細く形成され、且つ抜け止め部材２３を配管分岐部材１９にきつく螺合させてもチューブ基端口金２１を配管分岐部材１９にきつく押圧固定しない寸法形状に形成されている。   The retaining member 23 is a nut-like member in which a female screw to be engaged with a male screw formed on the outer peripheral portion of the pipe branching member 19 is formed in a half portion of the entire length, and the remaining half portion is The inner diameter is formed slightly narrower than the maximum outer diameter of the tube base end cap 21, and the tube base end cap 21 is not tightly pressed and fixed to the pipe branch member 19 even when the retaining member 23 is screwed into the pipe branch member 19 tightly. It is formed into a shape.

そのような構成により、抜け止め部材２３が配管分岐部材１９にきつく締め付けられると、処置具挿通チャンネル６の基端に固着されているチューブ基端口金２１が配管分岐部材１９に対して軸線２１ｘ方向には移動できないが、軸線２１ｘ周りには回転自在に配管分岐部材１９に対して接続された状態になり、その状態が維持される。   With such a configuration, when the retaining member 23 is tightly tightened to the pipe branching member 19, the tube base end cap 21 fixed to the proximal end of the treatment instrument insertion channel 6 is in the direction of the axis 21 x with respect to the pipe branching member 19. However, it is connected to the pipe branching member 19 so as to be rotatable around the axis 21x, and this state is maintained.

したがって、可撓性挿入部２が捩じられてそれと共に内部に挿通配置されている処置具挿通チャンネル６に大きな捩じり力が作用しても、処置具挿通チャンネル６が操作部１側の端部において配管分岐部材１９に対して軸線周りに自由に回転することができるので、処置具挿通チャンネル６が軸線周りに捩じれて座屈するような現象が発生しない。   Therefore, even if the flexible insertion portion 2 is twisted and a large torsional force is applied to the treatment instrument insertion channel 6 that is inserted and disposed inside the flexible insertion section 2, the treatment instrument insertion channel 6 remains on the operation portion 1 side. Since the end portion can freely rotate around the axis with respect to the pipe branching member 19, a phenomenon that the treatment instrument insertion channel 6 is twisted around the axis and buckled does not occur.

なお、本発明は上記実施例に限定されるものではなく、例えば、操作部１側において管路部材に対して軸線周りに回転自在に接続されるのが処置具挿通チャンネル６以外の可撓性チューブであっても差し支えなく、管路部材が配管分岐部材１９以外のシリンダ状部材その外の部材であっても差し支えない。   In addition, this invention is not limited to the said Example, For example, it is flexible other than the treatment tool penetration channel 6 that it is rotatably connected to a pipe line member around an axis line on the operation part 1 side. It may be a tube, and the pipe member may be a cylindrical member other than the pipe branching member 19 or other members.
