To assess the RF-induced heating of implants, three steps should be executed, including electromagnetic model construction, electromagnetic model validation, and virtual human body simulations. The crucial step of assessing RF-induced heating involves the construction of a test environment for electromagnetic model validation. In this study, a hardware environment, comprised of a RF generation system, electromagnetic field measurement system, and a robotic arm positioning system, was established. Furthermore, an automated control software environment was developed using a Python-based software development platform to enable the creation of a high-precision automated integrated test environment. The results indicate that the electric field generated in this test environment aligns well with the simulated electric field, making it suitable for assessing the RF-induced heating effects of implants.","PeriodicalId":52535,"journal":{"name":"Zhongguo yi liao qi xie za zhi = Chinese journal of medical instrumentation","volume":"48 3","pages":"281-284"},"PeriodicalIF":0.0,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141307378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Implantation of high-performance titanium alloy prosthesis is an effective method to treat bone defects. 3D printing technology can produce low-modulus titanium alloy implants with porous structures, providing a better solution to the above problems. This technology is convenient to design and has a huge advantage in making orthopedic implants. The article used electron beam melting in 3D printing technology to create two samples of Ti-6Al-4V prosthesis, including solid structural pelvic prosthesis and porous structural pelvic prosthesis. The mechanical properties of the prosthesis showed that the yield and tensile strengths of the rod tensile specimen were 894 MPa and 956 MPa, respectively, and the compressive modulus and compressive strength of the porous pelvic prosthesis were 55 GPa and 65.2 MPa, respectively. The results of the L929 cytotoxicity assay and the MC3T3-E1 cell adhesion assay demonstrated good biocompatibility of the prosthetic samples. New Zealand white rabbits were used to prepare the femoral joint cavity defect models and two pelvic prostheses were implanted. A microscopic CT scan 4 weeks after implantation showed that the bone defect caused by the drill had healed and that the porous structure of the pelvic prosthesis formed a new trabecular structure within the hole. In conclusion, the 3D printed Ti-6Al-4V pelvic prosthesis has excellent mechanical properties, biocompatibility, and the ability to promote new bone growth.","PeriodicalId":52535,"journal":{"name":"Zhongguo yi liao qi xie za zhi = Chinese journal of medical instrumentation","volume":"48 3","pages":"257-263"},"PeriodicalIF":0.0,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141307377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
