Embodiment Construction

[0022] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0023] In this embodiment, quality identification is performed for a fractured metal bone plate, and the specific identification steps are as follows:

[0024] Step 1: Test the type and basic size of the broken metal bone plate according to 3.4 Type and basic size of metal bone plate in YY 0017-2002 Standard for metal bone plate for osseointegrated implants. The metal bone plate is ZSZQ06 straight metal bone plate, and its basic dimensions are: d1=4.2mm, d2=6.3mm, δ=2.7mm. After testing, the size of the metal bone plate conforms to the type and basic size standard of 3.4 in the YY 0017-2002 standard;

[0025] Step 2: Use a surface stereomicroscope to inspect the fractured metal bone pla...

Abstract

The invention provides a method for identifying quality of a medical metal bone fracture plate and belongs to the field of quality identification of medical apparatus and instruments. According to the method, by aiming at mechanisms and principles of external causes and internal causes for the fracture of the metal bone fracture plate, through eight trace physical evidence measures, such as the type and dimensional measurement of the bone fracture plate, stereoscopic microscope examination, break electron microscopy observation, chemical component analysis on the metal bone fracture plate, nonmetal inclusion observation, hardness test, corrosion resistance test, mechanics performance test and the like, whether all performance parameters of the metal bone fracture plate meet the standard of the metal bone fracture plate or not is judged, and therefore, an effective objective identification result is given to the quality identification of the metal bone fracture plate.

Description

[0001] technical field [0002] The invention relates to a quality identification method of medical equipment, in particular to a quality identification method of medical bone plate. [0003] Background technique [0004] Medical metal bone plate belongs to the category of medical "bone joint implant". It is a medical device designed according to the shape of human bones and bionics. Some special metal plates are designed for the special shape and biomechanical needs of the two ends of the long bone. When the bone heals normally, the metal bone plate is placed on the internal splint of the fracture site, the purpose is to minimize the stress damage caused by the bending of the bone plate. At the same time, according to the different parts of the product, the screw hole spacing and hole diameter need to be determined, and the metal material should be determined according to the load-bearing requirements of the parts. It is a common medical device in surgical treatment. [...
