Description
本発明は、手術部に挿入する排液用ドレーンチューブに関するものである。 The present invention relates to a drainage drain tube to be inserted into a surgical site.
手術部は切開や摘出等により組織から出血があり，閉創後に体内に血液の貯留が起きないことが望ましい部位には排液用ドレーンチューブを留置する．脊椎手術では血液の貯留により神経が圧迫されると神経症状が引き起こされるためシリコーン等のドレーンチューブを挿入することが一般的である． In the surgical site, bleeding from the tissue due to incision or excision, etc., and a drainage drain tube should be placed at the site where it is desirable that blood does not accumulate in the body after closure. In spinal surgery, it is common to insert a drain tube such as silicone because nerves are caused when nerves are compressed due to blood accumulation.
排液ドレーンには閉鎖式と開放式があり，閉鎖式は図１のようにチューブ１にバッグ２等が接続しそれらに排液を貯める．開放式はバッグがなく創部にあてたガーゼ等に吸わせることになり，本体もチューブ形状とは限らない．閉鎖式ドレーンチューブは，チューブの先端側にある体液を吸引する部分である吸引部の形状は様々あり，円筒形で側面に多数の孔があいているもの（図２a）や，溝が縦にあるもの（図２ｂ）もある．吸引部の内部に隔壁がある場合もあり，その隔壁は「十」字であったり（図３a），「人」字であったり（図３b）する．ドレーンチューブは創部から直接出すものと，創部とは別の所からチューブを体外に出すものがある．後者はトロッカーという金属製で釘頭のない釘のようなものがチューブに接続しており，トロッカーにより創部とは別の所から表皮を貫いてドレーンチューブを体外に出してから，トロッカーは切り離されチューブとバッグをつないで使用する．開放式ドレーンには図４のようなペンローズドレーンという名称の柔軟な膜で内部に隔壁はなく多数の凹凸がついており，毛細管現象を利用して液を外部に導くものがある．開放式より閉鎖式ドレーンの方が体外からの逆流がなく細菌が体内に侵入しにくいため感染率が低い．創部とは別のところからドレーンチューブを出すようにするほうが同様に感染率は低いので多く用いられている． There are two types of drainage drains: a closed type and an open type. In the closed type, a bag 2 is connected to the tube 1 as shown in FIG. In the open type, there is no bag and the gauze or the like applied to the wound is sucked, and the body is not necessarily tube-shaped. The closed drain tube has various shapes of the suction part, which is the part that sucks the body fluid on the tip side of the tube, and has a cylindrical shape with many holes on the side (Fig. 2a), and the groove is vertically Some are (Figure 2b). There may be a partition inside the suction part, and the partition may be "ten" (Fig. 3a) or "person" (Fig. 3b). There are drain tubes that come directly from the wound, and drain tubes that come from outside the wound. The latter is a metal trocar like a nail that has no nail heads connected to the tube. The trocar penetrates the epidermis from a location separate from the wound and the drain tube is taken out of the body, and then the trocar is cut off. Connect the tube and bag. An open drain is a flexible membrane named Penrose drain as shown in Fig. 4, with no internal walls and many irregularities, and there is one that uses capillary action to guide the liquid to the outside. Closed drains have a lower infection rate than open ones because there is no backflow from outside the body and bacteria are less likely to enter the body. It is often used because the drainage rate is lower if the drain tube is taken out of the wound site.
脊椎手術に使用するドレーンチューブは先端側の吸引部が神経の近傍に留置されるため柔軟性が求められる．しかし柔軟性が高い素材ではチューブの管腔構造がつぶれやすく，既存の器具には先端部の柔軟性と吸引持続力を兼ね備えたものはない． The drain tube used for spinal surgery requires flexibility because the suction part on the tip side is placed near the nerve. However, the tube structure of the tube is easily crushed with a highly flexible material, and there is no existing device that combines the flexibility of the tip and the suction sustainability.
そこで、本発明の排液用ドレーンチューブは、その吸引部の形状により柔軟性と吸引持続力を兼ね備えたものにすることを目的とする。 Accordingly, an object of the drainage drain tube of the present invention is to have both flexibility and suction sustainability depending on the shape of the suction portion.
上記課題を解決するために本発明にかかる排液用ドレーンチューブは，閉鎖式ドレーンで「排液ドレーンチューブの吸引部の断面形状において，楕円もしくは角丸扁平四角形の外壁膜の内部に二つの隔壁が「V」字状にあり，三つの腔を形成し，中央腔には，隔壁の「V」字の下端の角にあたる所に溝があり，中央腔の両外側にある外側腔には，隔壁の「V」字の始点と終点にあたる所の外縁に溝があり，その溝は斜めに欠成されて」おり，「中央腔もしくは外側腔の溝の幅はチューブ長軸方向に沿って大小を繰り返している」ものである． In order to solve the above-mentioned problems, the drainage drain tube according to the present invention is a closed-type drain, “in the cross-sectional shape of the suction part of the drainage drain tube, there are two partition walls inside the outer wall membrane of an ellipse or a rounded rectangular shape. Is "V" -shaped, forming three cavities, the central cavity has a groove at the lower corner of the "V" shape of the septum, and the outer cavities on both outer sides of the central cavity are There is a groove on the outer edge of the partition wall at the start and end points of the “V”, and the groove is obliquely cut out. ”“ The width of the groove in the central or outer cavity is large or small along the tube long axis direction. Is repeated ".
前記角丸扁平四角形には四角形に半円や半楕円がその両端に接合している扁平な形状も含まれる。 The rounded rounded quadrangle includes a flat shape in which a semicircle or semi-ellipse is joined to both ends of the quadrangle.
バイパスチューブはドレーンチューブの吸引部以外の所のチューブのことで，既存する通常のものと同様に円筒形チューブである． The bypass tube is a tube other than the suction part of the drain tube, and is a cylindrical tube like the existing normal one.
図６で示すように本発明の排液用ドレーンチューブの吸引部は断面形状が扁平で，分枝がない一筆書き構造であることにより，扁平の短軸方向にたわみやすくなっている．たわみやすいため柔軟性に優れる．さらにたわんでも隔壁により内腔は確保される．図７で示すように膨大部がある溝構造により，吸引部がたわんで溝が閉鎖してしまっても膨大部は開存を保つため吸引力が確保される． As shown in FIG. 6, the suction part of the drainage drain tube of the present invention has a flat cross-sectional shape and a single-stroke structure with no branches, which makes it easy to bend in the flat minor axis direction. Excellent flexibility because it is flexible. Furthermore, the lumen is secured by the septum even when it bends. As shown in Fig. 7, the groove structure with the enormous part ensures the suction force because the enormous part remains open even if the suction part is bent and the groove is closed.
ドレーンチューブはトロッカーにて体内から表皮を突き破って体外に出して設置するが，トロッカー外径はバイパスチューブ外径と同じであり，出口である表皮の裂け目の大きさには余裕がない．ドレーンチューブを抜去する際にはその表皮の裂け目をドレーン吸引部も通ることになるが，ドレーン吸引部はバイパスチューブより横幅がある．外側腔の溝は斜めに欠成されていることによりドレーンチューブ抜去時には表皮の裂け目の所で外側腔が横から押されて溝の所でずれてつぶれるため，断面積が減り引っかかることなく抜去できる． The drain tube is installed with a trocar that penetrates the epidermis from the body and out of the body, but the outer diameter of the trocar is the same as the outer diameter of the bypass tube, and there is no allowance for the size of the tear at the outlet. When the drain tube is extracted, the drain suction part also passes through the rupture of the epidermis, but the drain suction part is wider than the bypass tube. Since the outer cavity groove is formed obliquely, when the drain tube is removed, the outer cavity is pushed from the side at the rupture of the epidermis and is displaced at the groove, so that the cross-sectional area decreases and can be removed without being caught. .
本発明の実施形態１を図５〜８を用いて説明する。ドレーンチューブはシリコーン等の軟性材で作られ，図５のように先端から吸引部３，バイパスチューブ部４，バッグ接続部５からなり，バッグ６に接続する．ドレーンチューブ吸引部３の断面形状は図６のように，楕円形の外壁膜７と，その内部に二つの隔壁８が「V」字状にあり，三つの腔を形成している．中央腔９には，隔壁８の「V」字の下端の角にあたる所にスリット溝１１がある．中央腔９の両外側にある外側腔１０には，隔壁８の「V」字の始点と終点にあたる所の外縁にスリット溝１２がある．スリット溝１２は斜めに欠成されている．図７のようにスリット溝１１，１２の幅はチューブ長軸方向に沿って膨大部１３が間欠的にありその間が峡部１４となっている． A first embodiment of the present invention will be described with reference to FIGS. The drain tube is made of a soft material such as silicone and consists of a suction part 3, a bypass tube part 4 and a bag connection part 5 from the tip as shown in FIG. As shown in FIG. 6, the drain tube suction part 3 has an elliptical outer wall film 7 and two partition walls 8 in a “V” shape, forming three cavities. In the central cavity 9, there is a slit groove 11 at the lower corner of the “V” shape of the partition wall 8. In the outer cavity 10 on both outer sides of the central cavity 9, there are slit grooves 12 on the outer edges of the partition wall 8 at the start and end points of the “V” shape. The slit groove 12 is formed obliquely. As shown in FIG. 7, the width of the slit grooves 11 and 12 is such that the enormous portion 13 is intermittent along the tube long axis direction, and the gorge portion 14 is in between.
ドレーンチューブの断面がバイパスチューブ部では図８aのように円形で，吸引部へ形態が変化する部分では図８b，cのように移行する． The cross section of the drain tube is circular as shown in Fig. 8a in the bypass tube section, and moves to the suction section as shown in Figs. 8b and 8c.
本発明の実施形態２を図９にて説明する。吸引部断面は外壁膜７が長方形の両端に半楕円を加えたような外形となっている．その他は実施形態１と同様である．
A second embodiment of the present invention will be described with reference to FIG. The cross-section of the suction part has an outer wall film 7 with a semi-ellipse added to both ends of the rectangle. Others are the same as in the first embodiment.
