    • A medical instrument includes a swingable operating section formed of a pair of forceps which rock around a first rocking axis. A tubular sheath includes a distal end portion situated on a proximal end side of the operating section having a circular-section portion having a circular cross-section perpendicular to a longitudinal central axis and a pair of flat portions formed by cutting the opposite sides of the circular-section portion and in sliding contact with the proximal end portions of the forceps. A manipulator advances and retreats in a longitudinal direction of the sheath, thereby rocking the forceps. A junction connects the manipulator for rocking motion around a second rocking axis with respect to the forceps in the flat portions, and is situated on or near a reference plane passing through the longitudinal central axis of the sheath and extending parallel to the second rocking axis when the operating section is closed.
    • 医疗器械包括由围绕第一摇摆轴线摇摆的一对镊子形成的可摆动操作部分。 管状护套包括位于操作部分的近端侧的远端部分,其具有圆形截面部分,该圆形截面部分具有垂直于纵向中心轴线的圆形横截面,以及一对平坦部分,其通过切割 圆形截面部分并与镊子的近端部分滑动接触。 操纵器沿护套的纵向前进和后退,从而摇动镊子。 接头将操纵器相对于平坦部分中的镊子连接围绕第二摇摆轴线的摆动运动,并且位于穿过护套的纵向中心轴线的参考平面上或附近,并且平行于第二摇摆轴线延伸, 操作部分关闭。
