Description

【０００１】
【発明の属する技術分野】
本発明は、例えば解離性大動脈瘤に対する手術等の血管の手術において使用される血管用クリップに関する。
【０００２】
【従来の技術】
従来、解離性大動脈瘤の外科手術では、瘤を切除後、フェルトを補強材にして血管の縫合を行っていた。図１は、この外科手術における血管縫合の状態を示す図である。解離性大動脈瘤の切除後、血管壁は内膜１と外膜とに解離し、それらの間には解離腔３が生じている。現在、ＧＲＦグルーと称される生体接着剤（以下、グルーという）の普及によって、この解離腔３内にグルーを流し込み、内膜１と外膜２とを接着し、血管壁外側にフェルトを帯状に巻き付け、縫合糸４で縫合する処置が行われている。
【０００３】
そして従来、解離腔３内にグルーを流し込み、内膜１と外膜２とを接着固定するために、グルーを流し込んだ部分をグルーが固まるまで保持しておくための器具として、血管壁を挟むための簡易クリップや、両端が湾曲板状に形成されたクランプが提供されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、従来のクリップやクランプを用いて解離腔を処置するには、解離腔にグルーを注入後、血管壁をクリップやクランプを用いて挟みつけ、グルーが固化した後にこれらを外し、その後で縫合しなければならず、余分な時間がかかり、手術時間の延長を招いていた。
【０００５】
本発明は上記事情に鑑みてなされたもので、解離腔にグルーを注入後、血管壁を保持しながら、その部分の縫合を可能とすることによって、手術時間の短縮を図ることのできる血管用クリップの提供を目的としている。
【０００６】
【課題を解決するための手段】
上記目的を達成するため、本発明は、把持部と、その先端に設けられた湾曲櫛状をなす第１の保持片と、該第１の保持片と接近・離間するように回動自在に上記把持部に設けられた湾曲櫛状をなす第２の保持片と、該第２の保持片を第１の保持片から離間する方向に移動させる操作レバーと、該第２の保持片を第１の保持片と接近する方向に付勢する付勢手段とを含み、前記第１の保持片と第２の保持片とを接近させた状態で、第１の保持片と第２の保持片との櫛歯間のスリットが重なり合うように構成されたことを特徴とする血管用クリップを提供する。
【０００７】
本発明の血管用クリップは、操作レバーの操作によって第２の保持片を第１の保持片から離間させた状態で、第１、第２の保持片間に血管壁を挿入し、操作レバーを離すと、付勢部材により第２の保持片が第１の保持片と接近する方向に移動して両方の保持片間に血管壁が保持される。この血管壁保持状態において、この血管用クリップは、第１の保持片と第２の保持片とが湾曲櫛状に形成され、かつ双方の櫛歯間のスリットが重なり合うように構成されているので、このスリットを利用して血管の縫合作業を行うことができる。従って、本発明の血管用クリップは、解離腔にグルーを注入後、簡単に該部分を保持できるとともに、グルーの固化前に血管の縫合が可能となるので、手術時間を短縮できる。
【０００８】
本発明の血管用クリップにおいて、第１の保持片と第２の保持片とが、これら保持片を接近させた状態で両者間に隙間を設けた構成とすることが好ましい。さらに、この隙間は保持するべき血管壁等の厚さを考慮して設定するのが好ましく、通常は０．５ｍｍ〜３．０ｍｍ程度、好ましくは１．０ｍｍ〜１．５ｍｍ程度とされる。
