Description
本願は、2014年8月19日に日本国に出願された特願2014−166318号に基づき優先権を主張し、その内容をここに援用する。
以下、本発明の第1実施形態について、図1から図10を参照して説明する。図1は、本実施形態に係る医療用処置具1と共に使用される内視鏡100を示す図である。
次に、本発明の第2実施形態について、図11から図17を参照して説明する。本実施形態に係る医療用処置具201は、スタイレット30を備えていない点で第1実施形態に係る医療用処置具1と異なる。また、本実施形態に係る医療用処置具201は、針10の先端部及びシース40の先端部の構成が第1実施形態に係る医療用処置具1とは異なる。なお、第1実施形態に係る医療用処置具1と同様の構成を有する部分については、その詳細な説明を省略する。
10、210 針
12、212 先端部
14、214 収容部
16 細径部
18、218 スリット
30 スタイレット
34 大径部
40、240 シース
本発明の第五の態様によれば、前記第一の態様に係る医療用処置具において、前記大径部が前記細径部と嵌合している位置から前記スタイレットを基端側に引くことによって、前記大径部が前記細径部から外れると、前記収容部が閉じてもよい。
Claims (4)
