【発明の詳細な説明】 本発明は、腎盂結石の採取に使用する腎盂鉗子
に関する。
第１図で示すものは従来より広く用いられてい

また、指掛け４，４の動きがじかに把持片２，２
に伝達されるため、微妙な操作を可能にする利点
がある。
反面、このてこ式腎盂鉗子１は、その採石操作

ができず、せつかく結石を把持しても切開部より
抜き出すことができない不都合がある。つまり、
操作性が悪いとともに、確実性がなく、実用的な
価値としてはきわめて低いものである。
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、てこ式の腎盂鉗子の操
作性を損うことなく、直視下において採石できる
ようにした腎盂鉗子を提供することにある。
以下、本発明の実施例を図面にもとづいて説明
する。
第３図は本発明の第１の実施例を示すものであ
る。すなわち、てこ式の腎盂鉗子を構成するもの
で、一対の柄１１，１２はビボツト１３によつて
枢着されてなり、各柄１１，１２の各先端には、
それぞれ把持片１４，１５が取り付けられてい

の連結部材１８，１９の先端に上記把持片１４，
１５を取り付けたものである。そして、把手部１
６，１７の先端側部分をビボツト１３によつて枢

それぞれ指掛け１６ａ，１７ａが設けられてい
て、この指掛け１６ａ，１７ａに親指と中指を掛
けて操作するようになつている。なお、上記連結
部材１８，１９は第３図で示すように湾曲されて
いる。
また、上記柄１１，１２の一方の連結部材１
８，１９、たとえば左側の連結部材１８を中空管
によつて形成し、さらに、この連結部材１８を手
元側に延出してなるものである。そして、この連
結部材１８の内部によつて後述するスコープ２０
を挿通させる挿通孔２１を形成するとともに、挿
通孔２１の先端を把持片１４の根元部分において
開口し、観察窓２２を形成するものである。ま
た、連結部材１８の手元端には上記スコープ２０
を挿入するための挿入口２３が形成されている。
さらに、挿入口２３の近くの側壁には、送水口２
４を設けてある。
なお、上記挿入口２３の内部には水の洩れるの
を防ぐ目的でスコープ２０との間を塞ぐパツキン
グ部材（図示しない）が設けられている。
しかして、上記実施例のてこ式の腎盂鉗子を用
いれば、スコープ２０を通じて観察しながら採石
操作を行なうことができる。すなわち、挿通孔２
１にスコープ２０を挿入し、これによつて把持片
１４，１５の根元側から直視できる。したがつて
直視下で結石を把持できるため、その操作が容易
かつ確実に行なうことができるとともに、操作時
間を大巾に短縮し、術者、患者双方の負担を軽減
することができる。また、スコープ２０によつて
直接に観察するので、結石の取り残しを防ぐこと
ができるとともに、Ｘ線によつて写らない結石も
採取可能である。
しかも、てこ式腎盂鉗子の基本構造をくずさな

把持した結石は、必ず取り出すことができる。
第４図は本発明の第２の実施例を示すもので、
これは送水口２５および送水チヤンネル２６を他
方の連結部材１９に設けるようにしたものであ

なお、第１の実施例では、挿入口２３と送水口
２４を別々に設けたが、これをまとめて１つにし

送水チヤンネルを使うとよいし、あるいはスコー
プ用挿入口２３に３方活栓などを取り付けること
により、スコープ用挿入口と送水口の働きを切り
換えてもよいものである。
第５図は本発明の第３の実施例を示すもので、
これは２つの柄１１，１２の把手部１６，１７を
異なる色で着色し、さらに、これと対応して各把
