    • A dental instrument comprises a handle member and a tool assembly. The handle member includes a first end, a second end and a longitudinal axis. The tool assembly extends from the first end of the handle member. The tool assembly comprises a tool arm, a first blade member and a second blade member. The tool arm has a proximal end extending from the first end of the handle and a distal end spaced therefrom. The first blade member extends away from the distal end of the tool arm and has a first flattened region. The second blade member extends away from the distal end of the tool arm and has a second flattened region. The first and second flattened regions are substantially perpendicular to each other in one dimension. The first blade member is configured for substantially transverse movement within a mouth of a patient. The second blade member is configured for substantially longitudinal movement within a mouth of a patient. Rotation of the handle member about the longitudinal axis thereof alternatively places one of the first and second blade member in an operative position.
    • 牙科器械包括手柄构件和工具组件。 手柄构件包括第一端,第二端和纵向轴线。 工具组件从手柄构件的第一端延伸。 工具组件包括工具臂,第一刀片构件和第二刀片构件。 工具臂具有从手柄的第一端延伸的近端和与其间隔开的远端。 第一刀片构件远离工具臂的远端延伸并且具有第一扁平区域。 第二刀片构件远离工具臂的远端延伸并且具有第二扁平区域。 第一和第二扁平区域在一个维度上基本上彼此垂直。 第一叶片构件构造成用于在患者的口中基本上横向移动。 第二叶片构件构造成在患者的口中基本纵向移动。 手柄构件围绕其纵向轴线的旋转可选地将第一和第二叶片构件中的一个置于操作位置。
