Medical electronic devices are expected to "print" in the body to achieve a high degree of minimally invasive

On the 17th, it was learned from the Chinese Academy of Sciences that the joint team of Tsinghua University and the Institute of Physics and Chemistry of the Chinese Academy of Sciences, led by Professor Liu Jing, proposed a 3D printing technology for implantable biomedical electronic devices based on liquid metal. This approach opens up a whole new way to offer new ways of implanting medical devices. Related research articles were published in the recent Science Publishing Group series of scientific reports.

Liu Jing introduced that by using the principle of 3D printing, by controlling the needle direction, injection site, injection volume, needle displacement and speed of the micro-injector, researchers have proposed a method of injecting ink directly into the target tissue in vivo in a minimally invasive manner. Injection molded medical electronic device carrier manufacturing method.

In the past, clinically used implantable medical devices such as brain pacemakers and pacemakers were often cumbersome and traumatic. Patients often had to undergo craniotomy, thoracotomy, device implantation, and wound suture. Wait for a series of complicated procedures. Not only will it cause physical and mental pain to the patient, but the wound is too large and can cause surgical complications and infection risks. This convenient and fast in-body flexible electronic device direct printing manufacturing method will advance the advancement of smart implantable medical electronic technology while alleviating the burden on patients.

“Because all devices and units are implemented by micro-needle-based liquid phase injection, the whole surgical procedure has achieved a high degree of minimally invasiveness.” Liu Jing said that if the surgical robot is further used, the steps will be greatly simplified.
