Information
"Physical health" is a blessing commonly used by people, which is intended to bless the other party to be able to stay away from the disease and maintain a happy body state. However, contrary to good wishes, people will inevitably have physical discomforts in life, ranging from colds and fevers to pneumonia and myocardial infarction, which will make people weak and tired.
With the accelerated coverage of China's basic medical facilities and the continuous improvement of online resource sharing platforms, the conditions for medical treatment of people everywhere have gradually improved, and cutting-edge medical technology has also been integrated into multiple aspects of appointment registration, remote diagnosis, surgical treatment, and drug traceability Among them, 3D printed surgical guides, delay correctors and other products are also well known to more and more patients.
The hot application of 3D printing in the medical field has also attracted great attention from medical experts and scholars. Expanding the practical application scenarios of 3D printing and exploring the trends and directions of 3D printing technology upgrades will help stimulate the potential of 3D printing and fully release the potential of 3D printing.
After hard exploration and repeated attempts, 3D printing-related materials research and technology research and development have made significant progress, and 4D printing has appeared in front of people. As a whole, 4D printing technology is a new technology that combines intelligent material structures with 3D printing technology. Based on 3D printing, the smart material structure is stimulated by the external environment, and its structure will change over time, thereby adding a time dimension to the three-dimensional object.
Each technology has its characteristics and specific applicability. It is obviously not desirable to confuse 3D printing with 4D printing. Some features of 4D printing are not available in 3D printing. In summary, 4D printing technology can change the traditional "mechanical transmission + motor drive" mode, allowing objects to self-assemble in places that are difficult to reach, such as human organs, underground pipelines, and spacecraft.
A new study in the medical field recently, such as a lightning, illuminates the "sky" of smart medical treatment. So what exactly is this study? Let us understand the situation.
Recently, a research group of Professor Leng Jinsong of the Institute of Composite Materials and Structures of Harbin Institute of Technology recently published a 4D printing biodegradable and remote-driven control shape memory seal in the international authoritative journal Advanced Functional Materials The academic article "Blocking Device" explores the possibility of 4D printing shape memory blocking devices from the perspective of medical and industrial integration, and gives a positive answer.
此 Before this, metal occluders were generally used in the industry for common atrial septal defect diseases in cardiovascular medicine. The problems of non-degradable, poorly biocompatible, allergic, and corrosive metal occluders have been difficult to solve. The majority of researchers have been actively researching for many years, hoping to develop an occlusion device that is biodegradable, has good histocompatibility, few complications, and can disappear automatically after the repair of the heart "hole".
The achievement of this research result shows to some extent that the landing of 4D printed polymer occluder is very likely. Combining programmable shape memory polymers with 4D printing technology to create a new shape memory polymer occluder is of great significance for the treatment of typical congenital heart disease, such as atrial septal defect. To turn this research result into reality, we need to cross multiple barriers such as core technology and industry norms.
In the big picture of the entire medical industry, cutting-edge technology undoubtedly occupies an important sector. Especially in the context of intelligent medical treatment and digital transformation and upgrading, cutting-edge technologies such as 3D printing and 4D printing should be paid more attention to. Breakthroughs in related technologies will also be a very beautiful piece of the smart medical map.
According to statistics, China's smart medical care exceeded 70 billion yuan in 2018, and the country strongly supports the development of smart medical care. It is estimated that by 2020, the sales scale of the smart medical market will approach 120 billion yuan. Such a vast market space will also attract more technology giants and technology research and development institutions to invest a lot of time and energy to actively promote the application of various technologies such as 3D printing, the Internet of Things, and 4D printing.
4D printing is one of the more promising technologies in the medical field, and its application value in the field of smart medical care cannot be underestimated. Orthopedics, dentistry, dermatology, etc. will provide a wide space for the application of 4D printing technology. Aerospace, electrical automation, tissue engineering, medical equipment, drug delivery vehicles and other fields are also considered as the key areas for 4D printing. Perhaps in the not-too-distant future, we will be able to see 4D printed polymer occluders on a large scale and bring more possibilities for patients to regain their health.
