Description
【０００１】[0001]
本考案は、内視鏡や処理具等の医療器具を体内の生体管路に挿入案内するため のガイド装置に関する。 The present invention relates to a guide device for inserting and guiding a medical instrument such as an endoscope or a treatment tool into a living body duct in a body.
【０００２】[0002]
近年、手術の方法が人体に大きな切開を加えて手で直接に処置する手技のもの から、小さな切開口から内視鏡や処置具の医療器具を、例えば腹腔等に挿入して ＴＶカメラで観察しながら誘導し、処置する手技へ急速に移行しつつある。これ らの手技の１つとして、生体管路、例えば胆道のような管腔に腹腔内視鏡による 観察下で、軟性内視鏡を挿入して管腔の中を観察したり、軟性内視鏡の鉗子チャ ンネルに処置具を通して生体管腔内を処置することが行われる。 In recent years, the method of surgery is one in which a large incision is made in the human body and the procedure is performed directly by hand. From a small incision, a medical instrument such as an endoscope or a treatment tool is inserted into the abdominal cavity, etc. However, the procedure of guiding and treating is rapidly shifting. As one of these procedures, a flexible endoscope is inserted into a lumen of a living body such as a biliary tract under observation with a laparoscope to observe the inside of the lumen or a flexible endoscope. The inside of a living body lumen is treated by passing a treatment tool through a forceps channel of a mirror.
【０００３】 この場合、生体管部の一部を切開して差込み口をあけ、そこに、軟性内視鏡の 挿入部の先端を入れて処置することになる。In this case, a part of the living body tube is incised to open an insertion port, and the distal end of the insertion portion of the flexible endoscope is inserted therein for treatment.
【０００４】 しかしながら、生体管路の内径は、一般に内視鏡挿入部の外径に比べて細い。 一方、軟性内視鏡挿入部の先端は鈍な端面として形成される。また、挿入部が非 常に柔らかいため、直接に生体管路内に導入することが一般に困難な状況にであ った。However, the inner diameter of the biological conduit is generally smaller than the outer diameter of the endoscope insertion portion. On the other hand, the tip of the flexible endoscope insertion portion is formed as a blunt end surface. In addition, since the insertion part is extremely soft, it was generally difficult to introduce it directly into the body duct.
【０００５】[0005]
そこで、バルーンの使用目的は多少異なるが、実開昭62−12301 号公報で示さ れているようなバルーン付きガイドシースを用いて、まず、生体管路の管腔をバ ルーン拡張しておいてから、そのガイドシース内を通して内視鏡を体内の生体管 路内に挿入するという手技が考えられる。 Therefore, although the purpose of use of the balloon is slightly different, first, the lumen of the biological duct is balloon-expanded by using a guide sheath with a balloon as shown in Japanese Utility Model Laid-Open No. 62-12301. Therefore, it is conceivable to insert the endoscope through the guide sheath into the living body tube in the body.
【０００６】 しかしながら、従来、提案されているバルーン付きガイドシースは、その先端 部の外径がガイドシースの部分と略同径であり、その先端は鈍な端面として形成 されるため、ガイドシースの先端部を体内の生体管体の切開した差込み口からそ の内部へ挿入することが、かなり難しい。However, in the conventionally proposed guide sheath with a balloon, the outer diameter of the distal end portion is substantially the same as that of the guide sheath portion, and the distal end is formed as a blunt end surface. It is quite difficult to insert the tip into the body through the incised opening of the body tube of the body.
【０００７】 本考案は前記課題に着目してなされたものであり、その目的とするところは、 医療器具を誘導案内するガイドシースの先端部を容易に生体管路内に挿入でき、 内視鏡等をそのガイドシースから生体管路へ円滑に誘導して挿通できるガイド装 置を提供することにある。The present invention has been made in view of the above problems, and an object thereof is to allow the distal end portion of a guide sheath for guiding and guiding a medical device to be easily inserted into a living body duct. It is intended to provide a guide device capable of smoothly guiding and inserting the like from the guide sheath into the living body duct.
【０００８】[0008]
本考案は、ガイドシースを用いて内視鏡や処置具の医療器具の挿入部を生体内 の管腔に導入するためのガイド装置において、前記ガイドシースの先端に、前方 が細い錘形状に収縮自在な先端部材を連設し、この先端部材の外周にはリング状 のバルーンを配設し、このバルーンには流体管路を通じて流体を送り込めるよう にした。 The present invention is a guide device for introducing an insertion portion of an endoscope or a medical instrument such as a treatment instrument into a lumen in a living body by using a guide sheath, wherein the tip of the guide sheath is contracted into a thin cone shape in front. A flexible tip member was connected in series, and a ring-shaped balloon was arranged on the outer circumference of this tip member, and fluid could be sent to this balloon through a fluid conduit.
【０００９】 これによれば、まず、バルーンを萎ませた状態で、体内の生体管体にあらかじ め設けた切口にガイドシースの先端部材を挿入する。このとき、ガイドシースの 先端部材は先端側が細い略錘状に形成されているので、その管路内へ容易に差込 める。ついで、バルーンに空気を送り込み、バルーンを膨脹させて管腔を拡張す る。 さらに、一旦、バルーンを収縮してガイドシースを押し進める。そして、この 動作を繰り返すことにより、十分な長さにわたって生体管腔を拡張してガイドシ ースを挿入できたら、最終的にバルーンを萎ませる。 そして、このガイドシース内に内視鏡等の挿入部を挿入してゆくと、その挿入 部先端で先端部材を押し拡げながら、医療器具を生体管路に挿入することができ る。According to this, first, with the balloon deflated, the distal end member of the guide sheath is inserted into a cut portion that is preliminarily provided in the living body tubular body in the body. At this time, since the distal end member of the guide sheath is formed in a substantially cone-like shape with a thin distal end side, it can be easily inserted into the conduit. Air is then delivered to the balloon to inflate the balloon and dilate the lumen. Furthermore, the balloon is once deflated and the guide sheath is pushed forward. Then, by repeating this operation, if the living body lumen can be expanded over a sufficient length and the guide sheath can be inserted, the balloon is finally deflated. Then, when an insertion portion such as an endoscope is inserted into this guide sheath, the medical instrument can be inserted into the living body duct while pushing the tip member away with the tip of the insertion portion.

【実施例】 本考案の第１の実施例を図１〜図６にもとづいて説明する。図１はそのガイド 装置１の外観を示す斜視図、図２はその側面の断面図、図３は図２中、Ａ−Ａ線 に沿った断面図である。First Embodiment A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing the outer appearance of the guide device 1, FIG. 2 is a side sectional view thereof, and FIG. 3 is a sectional view taken along the line AA in FIG.
【００１１】 ガイド装置１のガイドシース２は、軟性の樹脂で円筒状に成形されており、そ の胴部の内径は、これを用いる、例えば内視鏡の挿入部が挿通できる大きさに設 けられている。ガイドシース２の先端には、略円錘状で先細りに形成される先端 部材３が連設されている。先端部材３の内外径は、円錘の状態で、ガイドシース ２の胴部内径よりも小さくなっている。The guide sheath 2 of the guide device 1 is formed of a soft resin into a cylindrical shape, and the inner diameter of its barrel portion is set to such a size that, for example, the insertion portion of an endoscope can be inserted therethrough. It has been burned. At the tip of the guide sheath 2, a substantially cone-shaped and tapered tip member 3 is connected. The inner and outer diameters of the tip member 3 are smaller than the inner diameter of the body portion of the guide sheath 2 in the state of a circular cone.
【００１２】 この実施例において、先端部材３は、ガイドシース２の先端部分に、その軸方 向に沿って所定間隔で複数の切欠き４を形成してなり、この結果、形成される複 数の帯状片５によって、前方が細い円錘形状に収縮自在な先端部材３を構成して いる。すなわち、この実施例では、ガイドシース２の本体と先端部材３とが一体 的に連設している。In this embodiment, the tip member 3 is formed by forming a plurality of notches 4 along the axial direction of the tip portion of the guide sheath 2 at predetermined intervals, and as a result, a plurality of formed notches 4 are formed. The strip-shaped piece 5 constitutes a tip member 3 which can contract in the shape of a cone having a thin front. That is, in this embodiment, the main body of the guide sheath 2 and the tip member 3 are integrally connected.
【００１３】 また、この先端部材３の外周面には、その先端部材３を囲むようにリング状の バルーン６が接着固定されている。前記切欠き４の部分に対応するバルーン６の 内面部分はたるみ部７として形成される。このたるみ部７はバルーン６が収縮し たとき、図３で示すようにたるむ。このときのたるみ量は、ガイドシース２内に 内視鏡の挿入部を通したとき、先端部材３の内径が、その挿入部を十分に通せる 大きさに拡がることができる量に設定されている。また、膨らませたときのバル ーン６の外径は、ガイドシース２の胴部外径よりも大きくなるように設けられて いる。なお、バルーン６は収縮したとき、極力弛むことなく、先端部材３の外面 に極力密着するようにする。A ring-shaped balloon 6 is adhered and fixed to the outer peripheral surface of the tip member 3 so as to surround the tip member 3. An inner surface portion of the balloon 6 corresponding to the portion of the cutout 4 is formed as a slack portion 7. The slack portion 7 sags as shown in FIG. 3 when the balloon 6 is deflated. The amount of slack at this time is set so that when the insertion portion of the endoscope is passed through the guide sheath 2, the inner diameter of the distal end member 3 can be expanded to a size that allows the insertion portion to be sufficiently passed therethrough. There is. The outer diameter of the balloon 6 when inflated is set to be larger than the outer diameter of the body of the guide sheath 2. When the balloon 6 is deflated, the balloon 6 does not sag as much as possible and is brought into close contact with the outer surface of the tip member 3 as much as possible.
【００１４】 バルーン６の内部には、流体管路用の送気チューブ８の一端が連通され、気密 的に接続固定されている。そして、空気等の気体を送気チューブ８を通じて前記 バルーン６の内部へ送り込める。この送気チューブ８は、ガイドシース２の胴部 内面に軸方向に沿って固定されている。送気チューブ８の他端はガイドシース２ の後端でガイドシース２の外部へ導出し、図示しない送気装置へ接続される。Inside the balloon 6, one end of an air supply tube 8 for a fluid conduit is communicated, and airtightly connected and fixed. Then, a gas such as air can be fed into the balloon 6 through the gas feeding tube 8. The air supply tube 8 is fixed to the inner surface of the body of the guide sheath 2 along the axial direction. The other end of the air supply tube 8 is led out of the guide sheath 2 at the rear end of the guide sheath 2 and connected to an air supply device (not shown).
【００１５】 なお、送気チューブ８はガイドシース２の本体と一体に成形したものでもよい 。また、ガイドシース２の基端縁部９は、ラッパ状に拡がっている。また、ガイ ドシース２の基端に、挿入用スリットを形成した弾性気密弁（図示しない。）を 設けてもよい。The air supply tube 8 may be formed integrally with the main body of the guide sheath 2. Further, the base end edge portion 9 of the guide sheath 2 is expanded in a trumpet shape. Further, an elastic airtight valve (not shown) having an insertion slit may be provided at the base end of the guide sheath 2.
【００１６】 次に、図４から図６を参照して、このガイド装置１の作用を説明する。 まず、図４で示すように、体内の生体管体１１に切開を加え、その切り口１２ から、予め、バルーン６を萎ませた、ガイドシース２の先端部材３の部分を挿入 する。Next, the operation of the guide device 1 will be described with reference to FIGS. 4 to 6. First, as shown in FIG. 4, an incision is made in the living body tubular body 11 in the body, and the portion of the distal end member 3 of the guide sheath 2 in which the balloon 6 is deflated in advance is inserted from the cut 12 thereof.
【００１７】 そこで、図５で示すように、送気チューブ８よりバルーン６の内部に空気を送 り込み、そのバルーン６を膨らませる。バルーン６は生体管体１１の内腔を押し 拡げる。その押し拡げられた内腔の部分はガイドシース２の胴部外径よりも大き く拡げられる。Therefore, as shown in FIG. 5, air is blown into the balloon 6 from the air feeding tube 8 to inflate the balloon 6. The balloon 6 pushes and expands the inner cavity of the living body tube 11. The part of the expanded inner cavity is expanded to be larger than the outer diameter of the body of the guide sheath 2.
【００１８】 この後、バルーン６を萎ませても、押し拡げられた内腔の部分は、急には元に 戻らない。このため、切り口１２から生体管体１１の腔内にガイドシース２の先 端を前進さる。After that, even if the balloon 6 is deflated, the portion of the lumen that has been expanded is not suddenly restored. Therefore, the front end of the guide sheath 2 is advanced from the cut end 12 into the cavity of the living body tube 11.
【００１９】 そして、この動作を繰り返すことにより、十分な長さにわたって生体管体１１ の内腔を拡張してガイドシース２を挿入できたら、図６で示すように、最終的に バルーン６を萎ませる。このガイドシース２内に内視鏡等の挿入部１３を挿入す る。挿入部１３を挿入すると、その挿入部先端で先端部材３を押し拡げながら、 生体管体内まで挿入案内することができる。Then, by repeating this operation, if the lumen of the living body tube 11 can be expanded and the guide sheath 2 can be inserted over a sufficient length, the balloon 6 is finally deflated as shown in FIG. No The insertion portion 13 such as an endoscope is inserted into the guide sheath 2. When the insertion portion 13 is inserted, the tip member 3 can be pushed and expanded by the tip of the insertion portion, and the insertion can be guided into the body tube.
【００２０】 図７は本考案の第２の実施例を示すものである。これは前述した第１の実施例 における先端部材３の帯状片５の最先端に、その内側に突出した球面状の突起１ ５を設ける。その他の構成および作用は第１の実施例と同じである。これによる と、内視鏡や処置具等の医療器具の挿入部分を挿脱したとき、先端部材３の帯状 片５の最先端で、それらの挿入部分の外表面を傷付けることがない。FIG. 7 shows a second embodiment of the present invention. This is provided with a spherical projection 15 projecting inward at the tip of the strip 5 of the tip member 3 in the first embodiment described above. Other configurations and operations are the same as those in the first embodiment. According to this, when the insertion portion of the medical instrument such as the endoscope or the treatment tool is inserted and removed, the outer surface of the insertion portion is not damaged at the tip of the strip 5 of the tip member 3.
【００２１】 図８は本考案の第３の実施例を示すものである。これは前述した第１の実施例 における先端部材３を構成する帯状片５が、傾斜が異なる第１の斜面２０ａと第 ２の斜面２０ｂを形成してなり、その先端部材３を２段のテーパー形状に構成し たものである。第１の斜面２０ａは、第２の斜面２０ｂよりも、ガイドシース２ の軸方向に対してゆるやかな傾斜になっている。その他の構成および作用は第１ の実施例と同じである。この構成によると、先端側の第１の斜面２０ａがゆるや かでかつ径が小さく設けられているため、内径の小さい生体管路の内部に医療器 具を挿入しやすい。FIG. 8 shows a third embodiment of the present invention. This is because the strip-shaped piece 5 constituting the tip member 3 in the above-described first embodiment forms the first slope 20a and the second slope 20b having different inclinations, and the tip member 3 is tapered in two steps. It is configured into a shape. The first slope 20a has a gentler inclination with respect to the axial direction of the guide sheath 2 than the second slope 20b. Other configurations and operations are the same as those of the first embodiment. With this configuration, since the first slope 20a on the distal end side is provided with a gentle diameter and a small diameter, it is easy to insert the medical device into the inside of the living body conduit having a small inner diameter.
【００２２】 なお、本考案は前記実施例のものに限定されるものではなく、種々の変形例が 可能なものである。It should be noted that the present invention is not limited to the above embodiment, but various modifications are possible.
【００２３】[0023]
以上説明したように本考案によれば、生体管路内を拡張してガイドシースの先 端部を生体管腔内に容易に挿入でき、かつ、そのまま生体管腔の拡張、内視鏡等 の挿入まで連続的に行うことができる。このため、手術時間の短縮が大幅に図れ る。また、その作業自体も簡単であるため、術者の負担が少ない。 As described above, according to the present invention, the inside of the body lumen can be expanded to easily insert the distal end of the guide sheath into the body lumen, and the body lumen can be expanded as it is, and the guide sheath can be used for endoscopes, etc. The insertion can be performed continuously. Therefore, the operation time can be greatly shortened. Moreover, since the work itself is simple, the burden on the operator is small.
