1.1 本规范规定了用于沿骨干骨髓管切割圆柱形路径的铰刀的材料、尺寸和公差、光洁度和标记以及护理和处理要求。 1.2 髓内铰刀通常用于准备髓管，以便插入髓内固定装置（IMFD）。因此，考虑了髓内扩孔器直径与IMFD直径之间的关系。 1.3 单位-- 以国际单位制表示的值应被视为标准值。本标准不包括其他计量单位。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification provides requirements for material, dimensions and tolerances, finish and marking, and care and handling for reamers intended to cut a cylindrical path along the medullary canal of diaphyseal bone. 1.2 Intramedullary reamers are commonly used to prepare the medullary canal for the insertion of intramedullary fixation devices (IMFDs). As such, the relationship between the intramedullary reamer diameter and the IMFD's diameter are considered. 1.3 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
