Safe and precise surgical catheter guiding by robots

26/04/2021

Traditionally, the success of a minimally-invasive surgical (MIS) procedure is dependent on the clinician’s capabilities. Prominent MIS procedures include vascular surgeries, during which catheters are inserted into the body, steered to a target location, and used to treat a vascular disease. A particular challenge in vascular surgeries is the accurate positioning of the catheter tip.

Surgery in 3D: Virtual Reality in the OR

01/04/2021

Surgeons do not only have to gather theoretical knowledge and practice to perform successful interventions. They also need a good visual thinking and have to know the anatomical characteristics of each individual patient. Some of these tasks will become easier when Virtual and Mixed Reality bring three-dimensional, digital models into their profession.

Surgical planning with immersive mixed reality

01/04/2021

The job of surgeons starts long before they step into the operating room. They must use two-dimensional MRI or CT scans to plan the surgical steps on a three-dimensional patient, relying on their experience, skill, and spatial sense. Using mixed reality (MR) to view human anatomical models allows for better visualization and navigation.

Broader perspective: how Mixed and Virtual Reality transform surgery

01/04/2021

For surgeons, nothing is more important than intimate knowledge and a spatial understanding of their operating field. Yet even three-dimensional imaging methods only provide limited assistance because the data is viewed on two-dimensional screens. When it comes to surgical planning or medical education, Mixed and Virtual Reality foster a better spatial understanding of the human body.

Cardiovascular diseases: using AI to navigate the catheter

09/03/2020

Treatment of a heart attack or stroke caused by vascular occlusion must be prompt to prevent further damage to vital tissue. Unfortunately, the actual treatment is often preceded by a lengthy catheter-based procedure where the cardiologist manually guides the catheter to the affected vessel. AI might perform this task in the future.

Much-needed medical technology: a hospital for Togo

10/02/2020

If life has given you many blessings, you should share them with others – and you also need to be a little crazy. That's Dagmar Braun's point of view. She initiated the construction of a hospital in Togo, Africa. The country currently lacks the system required to deliver comprehensive medical care. Surgical equipment and gynecology devices are much-needed to compensate for these deficits.

Angiogenesis: light shows blood vessels the way

03/02/2020

Regenerative medicine aims to replace damage in the body with functional tissue and restore normal function. The first defense for large defects are implants made of hydrogels, designed to promote cell growth. They need their own blood supply, which is a problem when it comes to larger implants because you cannot regulate where and how the blood vessels grow - until now.

Endoprostheses: between possibility and reality

01/01/2020

When natural joints lose their ability to function, they can be completely or partially replaced by artificial joints, also called endoprostheses. Endoprostheses must be of a certain quality, as they should remain in the body as long as possible. In addition to some risks, endoprostheses can also contribute to a mobile and carefree life for young and old.

Endoprostheses: regaining independence and mobility

01/01/2020

Joints can suddenly or gradually deteriorate and lose their natural strength, whether it’s due to accidents, diseases or simple wear and tear. In some of these cases, implants of artificial joints – endoprostheses - can help. As a joint replacement, they are designed to stay in the body for as long as needed and as such improve the patient’s quality of life and mobility.

Tumor excision: triple imaging for unique diagnostics

08/08/2019

After their tumor has been removed, some patients have to return to the hospital to undergo surgery again. That's because the tumor was not precisely identified and was subsequently not completely removed. That's both an ethical and financial dilemma. A new surgery-adjacent procedure is designed to rapidly and accurately detect tumors.

Regenerative heart valves: from simulation to replacement

23/07/2018

Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.

Surgical navigation systems – with precision to the destination

06/03/2018

With the help of surgical navigation systems, prostheses or implants can be better inserted. During the procedure, surgeons can see exactly where they need to operate on a screen. Just like a navigation system in the car, navigation in the OR guides you precisely to your destination. At the Uniklinik RWTH Aachen we can find out what advantages this has for physicians and patients.
