YY/T 0119.2-2014Spinal implants—Components used in the surgical fixation of the spinal skeletal system - Part 2: Metallic spinal screws (English PDF)

Foreword

YY/T 0119 "was within the spinal implant spinal fixation system components" is divided into five sections.

--- Part 1. General requirements;

--- Part 2. Metal screws spine;

--- Part 3. Metal spine board;

--- Part 4. Metal spinal rod;

--- Part 5. Metal screw spinal static and fatigue bending strength Test method. This section YY/T Section 20119 of. This section drafted in accordance with GB/T 1.1-2009 given rules.

Used in this section refer to redraft the law ASTMF2193-07 "standard spinal fixation system components and test methods" in the Annex Record A1 and X2 preparation.

This standard and YY 0119-2002 "metal orthopedic implants osteosynthesis with nails", YY 0120-2002 "osteosynthesis implant metal Orthopedic stick, "the main differences.

--- YY 0119-2002, YY 0120-2002 in materials including stainless steel, titanium, and the new standard also includes titanium, thus

YY/T 0119-2014 broader scope;

--- YY/T 0119-2014 has also increased the relative performance testing of metal spine screws, metal plates and metal spine spinal rods.

Since the implementation of this section, instead of YY 0119-2002 "metal orthopedic implants osteosynthesis staple" relating to pedicle screws, vertebral Content sacrum nail body and nail. Generic companies can use passive metal surgical implant in accordance with this standard and reference YY 0341-2009 "osteosynthesis Technical conditions "content development of enterprise standards.
