PROBLEM TO BE SOLVED: To provide a jig for detachably holding a hollow needle, which can be detached by simple operation and reduces a risk that an exterior of the hollow needle is contaminated when the needle is attached.SOLUTION: A jig for holding a needle comprises: a fork-like head (5) allowing a hollow needle (12) to be inserted through interdentiums (56a, 56b, 57a and 57b) and a pressing piece (6) for pressing a side of the hollow needle to a base end (51) of the fork-like head at the interdentiums to hold the hollow needle between the pressing piece and the base end part. The jig may comprise: a stopper (71) for securing the pressing piece while holding the hollow needle between the stopper and the base end part via a pressing part (62). The pressing part may be swingably fixed to the pressing piece. The fork-like head may comprise a pair of fork-like parts parallely arranged and the pressing piece may be arranged between the pair of fork-like parts. The fork-like head may comprise: two or more interdentiums (56a and 57a) to hold two or more hollow needles.COPYRIGHT: (C)2014,JPO&INPIT【課題】中空針を着脱可能に保持する治具であって、簡単な操作で着脱が行え、かつ、中空針を取り付ける際に針の外側を汚染させる危険性を低減した治具を提供する。【解決手段】中空針(12)を歯間(56a,56b,57a,57b)に受け入れ可能なフォーク状頭部(5)と、中空針の側面を前記歯間にてフォーク状頭部の基端部(51)に押圧して、中空針を自身と基端部との間に挟持する押圧片(6)とを備えてなる針保持用治具。該治具は、中空針を自身と基端部との間に押圧部(62)を介して挟持した状態で押圧片を固定するストッパー(71)を備えてよい。押圧部は、押圧片に揺動可能に取り付けられてよい。フォーク状頭部は、平行して配置された一対のフォーク状部を備え、押圧片は前記一対のフォーク状部の間に配置されてよい。フォーク状頭部は2以上の歯間(56a,57a)を備えて、2本以上の中空針を保持できるようにしてもよい。【選択図】図1
