Biomedical materials refer to a class of materials with special properties that are different from traditional materials and that are necessary and safe for the human body. This kind of biomaterials have a wide range of applications in human implants and tissue repair. This article focuses on the research progress in the following three aspects: implant interventional apparatus, tissue repair materials, and cutting-edge technologies.
1 Orthopaedic implants
Orthopedic implant is one way to treat the musculoskeletal system. The main function of the implant is to completely or partially replace the human joint, bone, or musculoskeletal system. The three categories of product that most commonly used in the orthopedic implant market are: joint implants, spinal implants, and wound implants.
2 Cardiovascular implantation devices
In addition to implanting bones in the human body, the use of implants and interventional devices in the cardiovascular field are also very common. The most widely used products include coronary artery implantable medical devices (including stents, catheters, and guidewires), congenital heart disease implantable medical devices (including occluders, pacemakers, heart valves, etc), and cerebrovascular implant medical devices (including carotid artery stenting, vertebral artery stents, intracranial vascular stents, intracranial stents, microtubule, Microguide wire, etc) and peripheral vascular interventional devices (arterial stents, aortic aneurysm covered stent, femoral vein stents, etc).
3 New medical materials
The first time that new medical materials were applied to human tissue repairs dates back to 5,000 BC. China and Egypt began to use artificial teeth such as dentures and artificial hands in 2500 BC. In modern times, the first metal materials used in clinical practice were precious metals such as gold, silver, and platinum. The gold has been used to repair the zygomatic bone in 1588. Until the 1990s, with the development of nanomaterials, biotechnology and genetic engineering, the research of biologically viable materials have expanded into the field of materials with biological functions. In recent years, with the rapid advances in science and technology, refined and cutting-edge technologies have gained more and more attention from all over the world.
4 3D printing technology
3D printing, in fact, be called “rapid prototyping technology” in the professional field. The rapid prototyping technology, also known as Rapid Prototyping Manufacturing (RPM) technology, which was born in the late 1980s. It is a high-tech manufacturing technology based on the material stacking method and it is considered to be a major achievement in the manufacturing field in recent years. The 3D printing is a newly-developed technology in the manufacturing field and is known as "a manufacturing technology with revolutionary significance in the industry." The main production process of 3D printing technology is to use a computer software to design a three-dimensional processing pattern, and then use a special solid material to printing through a 3D printer. The 3D printing has been widely used in the fields of industrial manufacturing, cultural creativity and digital entertainment, aerospace, biomedicine, consumer products, construction engineering, education and personalized customization.
