Problem to be solved: to easily flexibly bend in two directions in the vicinity of the working part, and to provide a fine surgical forceps as a whole.The operating forceps are connected to the working portion, the support portion, the bending portion, the straight portion and the operating portion in this order.The operating section has a working operation section for operating the working portion and a bending operating portion for operating the bending of the bent portion.A single superelastic wire having a rod shape of 0.5 mm or less is used as a working wire for attaching one end to the working portion and attaching the other end to the working operation section as a working wire for superposing a resilient material.In addition, a superelastic wire is used as three or more bent wires for attaching one end to the support portion and attaching the other end to the bending operating portion.Diagram【課題】作業部の近傍で２方向の任意方向に容易に屈曲できると共に全体として細い手術用鉗子を提供する。【解決手段】手術用鉗子は、作業部と支持部と屈曲部と直線部と操作部とがこの順に連結されている。操作部は、作業部を操作する作業用操作部と、屈曲部の屈曲を操作する屈曲用操作部とを有する。作業部に一端を取り付けると共に作業用操作部に他端を取り付ける作業用ワイヤとして超弾性を有する金属材料により直径が０．５ｍｍ以下の棒状の単一の超弾性ワイヤを用いる。また、支持部に一端を取り付けると共に屈曲用操作部に他端を取り付ける３つ以上の屈曲用ワイヤとして超弾性ワイヤを用いる。【選択図】図１
