Analytical medical 3D printing titanium alloy artificial hip joint process
Today, as network technology gradually penetrates into the physical industry, the Internet has brought new opportunities for medical care . In August 2015, ICON Medical's 3D ACT artificial hip joint system was approved as the world's first clinically proven internal implant product. In order to fully demonstrate the unique advantages of 3D ACT, create a good atmosphere for users' online experience, and increase doctors' awareness of products, Aikang is launching the ITI (Image To Implant) technology platform, which is designed by Aikang. The software is the core, the network digital technology and 3D printing technology are closely combined to provide the surgeon with a complete set of systemic surgical solutions from images to implants. The platform is designed to fully exploit the digital 3D printing technology. The ability of pre-planning and virtual surgery enables a significant leap in the traditional surgical procedure with digital technology, and the transformation of traditional surgical models to improve the safety and accuracy of surgery. The following are the key services of the ITI platform:
The advantages of 3D printing technology in the 'personalization' of orthopedics:
The 3D metal printing artificial hip joint system is manufactured by advanced Electron Beam Melting (EBM). The surface is a three-dimensional mesh structure, which is very similar to the human cancellous bone trabeculae. The layer is melted and superimposed to produce a very good bone ingrowth effect.
According to the computer-aided design, 3D printing can quickly form the implant, and a fixed-size microporous structure can be prepared. These micropore structures can reduce the elastic modulus of the metal material and reduce the stress shielding on the implant, and promote the connection between the metal and bone on the implant surface.
The first 3D metal printed artificial hip joint system product listed in China was registered by Beijing Aikang (Yicheng) Medical Co., and was officially approved by the State Food and Drug Administration in August 2015. It has been approved by CFDA for Class III medical devices. The first clinically proven metal 3D metal print orthopedic implant product.
3D printing personalized implementation process:
1. Build and print a customized skeleton model
After obtaining the CT or MRI image data of the patient, the patient's real bone model is inversely simulated by the medical interaction software, and the three-dimensional modeling is performed in the computer, and the real situation of the bone is visually and stereoscopically displayed in front of the operator, which is the preoperative plan. Provide a basis for development; and, you can print out a 1:1 patient bone model, and let the doctor know the patient's bones better before surgery. It also reduces the risk of surgery or the operation time due to the lack of understanding of the patient's bone structure by the intraoperative doctor.
