Problem to be solved: to secure the position of the object to be imaged by medical steel tweezers, even if a strong rotational force is applied to the object to be grasped, the grasping position of the left and right medical steel tweezers grasped is not shifted to the left and right The purpose of the present invention is to provide a medical steel tweezers which can be grasped.The fine working tweezers according to the present invention hold the object of the operation at the right and left abutment surfaces 6 and 6 of the inner surface of the distal end of the tip portion, and the terminal portion of the gripping portion is located on the inner surface of the holding surface excluding the tip portion from the flat surface of the holding portion to the side of the gripping part A V-shaped groove having a triangular cross section in which a tip is pointed toward the depth side is formed on one inner surface of one of the opposing tweezers over a predetermined length of length, and a convex portion 4 having a triangular cross section is formed on the other inner surface of the pin groove 3 opposite to the V-groove 3.Diagram【課題】本発明は手術対象部位を医療用鋼製ピンセットで把持する場合において、把持対象部位に強い回転力が作用しようとも、把持している左右の医療用鋼製ピンセットの把持部位が左右にずれたりすることなく、確実に把持することができる医療用鋼製ピンセットを提供することを目的とする。【解決手段】本発明に係る精密作業用ピンセットは、先端部の内側内面の平坦な左右の当接面同士6、6で手術対象部位を把持し、該把持部の平坦な端末から所定長の対向面の一方に先端部を除く内面に把持部の端末近傍から所定長の長さに亘って対向するピンセットの一方の内面に深さ側に向けて先端が尖った断面三角形状のV溝3を形成し、該V溝3と対向する他方の内面に、断面三角形状の凸状部4を有する構造である。【選択図】図1
