Abstract
Description
針部と、
直線状に伸びた直線状部を有し、一端側が前記針部と繋がった本体とを備え、
眼球の内外を導通させるための管部材に前記針部を通した状態で前記直線状部を持って前記針部で眼球の外膜に穴をあけつつ前記管部材を前記外膜に刺さった状態にした後に前記針部を前記外膜から退避させることで前記管部材を前記外膜に刺さった状態に留置させるための器具であって、
前記管部材は、眼科手術の際に前記外膜に装着させるための部材であり、かつ眼科手術後に眼球から取り外される部材であり、
前記針部は前記直線状部に対して角度が付けられている。
以下、本発明の第1実施形態を図面を参照しつつ説明する。図1の眼科用器具1は、眼科手術の際に管部材10(図2参照)を被手術眼(眼球)の角膜に刺さった状態に留置させるための管部材留置用器具である。
次に第2実施形態を第1実施形態と異なる部分を中心に説明する。第1実施形態の管部材留置用器具は、本体が屈曲し、針部は屈曲していない構成であったが、第2実施形態の管部材留置用器具は、本体は屈曲しておらず、針部が屈曲した構成である。
次に第3実施形態を第1、第2実施形態と異なる部分を中心に説明する。第2実施形態の管部材留置用器具は、針部の途中に屈曲部を有した構成であったが、第3実施形態の管部材留置用器具は、針部の、本体から突出した部分の全体が本体に対して角度が付けられた構成である。
