Digital orthopedic technology: scan, customize, print

01/07/2021

When auxiliary means like orthoses or prostheses do not come from the shelf, but are adapted to the wearer, this means true crafting: In the past, a plaster mold of a body part had to be made as a template to create an individual aid from it step by step. Fortunately, we have come a long way until today.

COVID-19: better-fitting face masks greatly improve protection

18/06/2021

Even the best face masks work only as well as their fit. And poorly fitting face masks greatly increase the risk of infection from airborne pathogens compared to custom-fitted masks, according to a new study by the University of Cincinnati.

Stereotactic systems from the 3D printer

17/06/2021

Stereotactic systems are special devices used in neurosurgical procedures. Until now, conventional production methods have meant that these devices are not only expensive to manufacture, but are also geometrically limited.

Diabetes: new research a 'step change'

17/06/2021

Millions of people with diabetes are at risk of developing foot ulcers, which often lead to amputations and other health complications. Now, Scientists from the Centre for Biomechanics and Rehabilitation Technologies (CRBT) have developed a new method to reliably detect this risk without the need for complex electronic in-shoe sensors.

Smart implant – Healing fractures autonomously with smart materials

07/06/2021

Lower leg fractures put a great strain on patients due to their long healing process. In the future, an intelligent implant could control how the bone grows together again and thus optimize the healing process. In our video, you can learn from the developers at Saarland University how this works and what role artificial intelligence plays here.

Medical devices: hygienic design combats pathogens

03/02/2021

Medical hygiene does not just play a key role during the COVID-19 pandemic. Preventing the transmission of infectious diseases and especially the spread of multidrug-resistant organisms is paramount even in non-pandemic times. While hygiene practices in hospitals and medical offices are essential, the industry can also make an important contribution with hygienic product design.

Autonomous medical technology: independently in the body

01/02/2021

Therapies need to be carried out with high reliability by trained personal. This will not change in the future. But maybe we will be able to let systems in the patient’s body do some of the work. Some approaches are already aiming to make implants more independent so they will be able to flexibly react to changes. Read more in our Topic of the Month!

Intelligent implants: when the material is the key to the solution

01/02/2021

Today we use implants to stabilize or compensate for injuries inside the body and to aid in the healing process. Implants cannot act autonomously and treat the patient if they deem it necessary. However, it is just a matter of time before this happens because research on intelligent implant materials that respond to stimuli is on the cusp of a breakthrough.

Printed life – possibilities and limits of bioprinting

01/12/2020

Implants, prostheses and various other components made of plastic, metal or ceramics are already being produced by additive manufacturing. But skin, blood vessels or entire organs from the printer – is that possible? For years now, intensive research has been underway into the production of biologically functional tissue using printing processes. Some things are already possible with bioprinting.
