Study of Typical Functional Failure and Mechanical Properties of Non-absorbable Suture Anchor / 中国医疗器械杂志

OBJECTIVE@#To study the mechanical properties related to the typical functional failure modes of non-absorbable suture anchor in clinical use, and to support product design, development and verification.@*METHODS@#By retrieving the database of relevant adverse events, the typical functional failure modes of non-absorbable suture anchor were summarized, and the influencing factors of functional failure were further analyzed by studying the mechanical properties related to functional failure. The publicly available test data was retrieved for verification and provided reference for the researchers.@*RESULTS@#The typical functional failure modes of non-absorbable suture anchor include anchor failure, suture failure, fix loosening, inserter failure, which are related to the mechanical properties of products, such as screw-in torque and break torque of screw-in anchors, insertion force of knock-in anchors, suture strength, pull-out force before and after system fatigue test and elongation of sutures after fatigue test.@*CONCLUSIONS@#Enterprises should pay attention to improving the mechanical performance level of products through material, structural design and the suture weaving process to ensure the safety and effectiveness of products.

Concerns of Technical Evaluation on Registration of All-inside Meniscus Suture System / 中国医疗器械杂志

OBJECTIVE@#To summarize the product registration declaration ideas and registration technical review of the all-inside meniscal suture system, and to systematically think about of the technical review concerns of the all-inside meniscal suture system products to provide technical guidance for improving the quality of registration and application and regulatory efficiency.@*METHODS@#Consult the public information of such products at home and abroad, and summarize the experience of registration review of such products.@*RESULTS@#The technical review of the all-inside meniscus suture system registration mainly focuses on product basic information, pre-clinical research, clinical evaluation and product technical requirements.@*CONCLUSIONS@#The difficulty of product registration and declaration of the all-inside meniscus suture system lies in the provision of pre-clinical research data of the product, and the applicant needs to strengthen the basic research ability, formulate scientific technical indicators and test methods to ensure the safety and effectiveness of the product, and also provide sufficient supporting data for the registration declaration.
