ISO 7206-13:2016描述了一种在规定的实验室条件下确定所需扭矩的方法,以松开髋关节假体头部的固定,其中头部不打算相对于颈部旋转。它适用于全髋关节或部分髋关节置换术中的股骨组件,其中头部和颈部/柄(以下称为锥形)通过锁定锥形或任何其他方式固定在一起,头部和锥形是独立的组件,由金属或非金属材料制成。
它不包括检查试样的方法;测试实验室和提交样本进行测试的一方应就这些问题达成一致。
ISO 7206-13:2016 describes a method of determining the torque required, under specified laboratory conditions, to loosen the fixation of the head of hip joint prostheses in which the head is not intended to rotate relative to the neck. It applies to the femoral component of total or partial hip joint replacements in which the head and neck/stem (in the following referred to as cone) are secured together by a locking conical taper or any other means and in which the head and cone are separate components, and which are made of metallic or non-metallic materials.
It does not cover methods of examining the test specimens; these should be agreed between the test laboratory and the party submitting the specimen for test.
