13/10/2021Bone screws and plates that dissolve on their own after a broken bone has healed promise to be of great benefit. A research team has now used a 3D X-ray method to determine for the first time quantitatively how different of magnesium alloys dissolve over time under body-like conditions.
08/10/2021Risks during surgery, especially cardiological risks, are still very high in the Western world. However, conventional methods for measuring such risks before surgery are costly or even not always meaningful. And increasing economization in hospitals also makes it more difficult for staff to find time for a comprehensive pre-op analysis.
08/09/2021Focused ultrasound waves create microbubbles in a fluid – a phenomenon called cavitation. In a current study, this process is used to destroy liver tumors and metastases.
02/08/2021Robots in the operating theatre are no longer a rarity in certain medical fields - they support and relieve doctors and sometimes they can make operations more efficient and easier with artificial intelligence (AI). However, they are rarely found in the operating theatre during cardiological interventions.
02/08/2021A high degree of precision is required for operations involving the cardiovascular system. This is based on medical imaging. In practice, however, these still face a number of challenges that can impair image quality. The further development of imaging techniques represents a forward-looking field of research in order to be able to improve surgical treatment.
13/07/2021Kidney stones are a widespread disease. In order to be able to reliably remove even the smallest remnants of them, Purenum GmbH, a spin-off of Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM, developed a gel that encloses small fragments and can then be removed without leaving any residue. This year, the product mediNiK was certified and is thus ready for the market.
01/04/2021Surgeons have only limited options to practice surgical techniques before they enter the operating room. The implantation of an endoprosthesis requires extensive practical training since it necessitates strength and utmost precision. The "Dynamic HIPS" project develops a virtual reality hip implant simulator that provides realistic haptic feedback.
09/03/2021Robotics has been gaining importance in many areas of life for years, not least in medicine. Robots are already being used in the operating room today, but they do not always play the leading role – a circumstance that will certainly change in the long term.
15/12/2020Atrial fibrillation is an irregular heartbeat that can lead to blood clots and trigger strokes. To correct the condition, physicians use medication or surgical intervention by means of catheter ablation. This surgical method on the beating heart is a standard and safe procedure but there is always room for improvement.
08/10/2020Surgery can be very strenuous for a surgeon, as he often has to bend over the patient in a rigid position for hours. For the first time worldwide, a surgical microscope that can be controlled by head movements was used at the University Hospital Zurich. This makes surgery not only more comfortable, but also faster.
22/09/2020Patients who receive a prosthesis after the amputation of a limb often have to train for weeks or months until they can control the technology and use it in everyday life without problems. At the Medical University of Vienna, the world's first bionic prosthesis has now been developed that has a closed control loop and enables immediate, intuitive use.
10/08/2020This is how a conventional ultrasound scan works: patients lie down on a table next to the ultrasound machine. A doctor uses a probe to scan the part of the body in question, while he or she looks at the pictures on a monitor. In other words, the physician either focuses on his/her hand on the patient or the monitor. The Fraunhofer IGD wants to change this process as part of the "sonAR" project.
04/05/2020In the operating room, minimally invasive procedures are increasingly used. Robot-assisted systems are a great help for the surgeon. They support the surgeon and are extremely precise. Through innovative research approaches, robotic systems are constantly evolving.
04/05/2020Robotic surgical systems are often used to perform minimally invasive procedures. The daVinci surgical system is still one of the market leaders and is especially well suited to perform prostatectomies, a surgical option for prostate cancer.
04/05/2020More compact, more flexibility, and more precision - these are the main characteristics developers strive for as they advance robotic-assisted surgical systems for the operating room. Several technology providers have already shown how it’s done, including the makers of the popular daVinci Surgical System. Yet for robotic-assisted systems, the sky is the limit.
04/05/2020Surgical robots are transforming the operating room. They deliver many benefits but also present new challenges. That is why the efficient handling of robotic mechanisms must also be reflected in the respective training courses.
01/01/2020Joints 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.
01/01/2020Today, people tend to live longer, while an increasing number of patients suffer from osteoarthritis. Even younger generations are now at a higher risk of getting osteoarthritis due to the frequent use of mobile devices. The EU research project APRICOT aims to develop a novel type of implant for the treatment of osteoarthritis of the hands – helping patients heal themselves.
01/01/2020Surgery is required if you need an artificial joint. Patients and doctors must select the type of surgery that’s best suited and choose between robot-assisted, traditional or minimally invasive surgical approaches. Post-operative risks should be kept to a minimum, while benefits should outweigh any possible complications.
01/01/2020When 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.
08/08/2019After 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.
22/07/2019Modern imaging opens news doors to surgeries. Yet it also poses major problems for surgeons: They use two-dimensional images to navigate through a three-dimensional surgical environment, while they continuously have to switch their focus back and forth between the images and the patient. Now help is on the way in the form of interactive 3D projections and mixed reality (MR).
24/06/2019Improving technology transfer from research to industry and driving robotics development - that's the idea behind the KUKA Innovation Award. This year’s topic is "Healthy Living". Applicants from around the world were tasked with creating a robot application for healthcare settings. Now, the finalists, who will showcase their innovations at the MEDICA 2019 trade fair have been selected.
11/06/2019Epilepsy patients are currently treated with either medication or surgical options. The aim is to remove the distinct regions of the brain that cause epileptic seizures. Laser ablation for epilepsy is a new, catheter-based surgical procedure that is now also available in Europe, preventing patients from having to undergo open brain surgery.
01/04/2019A surgery already begins before the patient is lying on the operating table – namely with the planning. For example, if brain surgery is imminent, the brain must first be mapped. This makes the activity level of certain brain areas visible. Functional magnetic resonance imaging makes this possible.
01/04/2019Our brain is the command center of our body. This is where all information and impressions are collected and converted into responses and movements. Modern imaging techniques offer physicians and researchers unique insights into the actions of the human central nervous system. The functional imaging technique allows them to watch our brain in action.
13/11/2018Germ-free, fast and precise - in order for interventions in the OR to run safely and smoothly, the rooms have to be equipped with specific operating equipment. This must not only comply with hygiene standards, but also guarantee sufficient free space and fast retrieval of patient data. We are visiting MEDICA 2018 to learn more about these innovations.
08/11/2018Not enough exercise, an unhealthy diet: Kidney stones develop when urine contains too many insoluble compounds and are now one of the most common diseases worldwide. The ailment annually affects 1.2 million people in Germany alone. The stones are broken up and taken out via endoscopic surgery. Now it’s possible to remove even the tiniest residual fragments. The solution: a biocompatible adhesive.
03/09/2018In a Smart Hospital, all devices are designed to be connected and integrated, thus increasing efficiency and reducing time loss – at least, that is how things are meant to work in theory. In reality, there are still countless vendor-specific point solutions that cannot be integrated. That's why there is a need for solutions that bridge the gap between the different applications and formats.
23/07/2018Every 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.
08/05/2018Multidrug-resistant organisms that are treated with a dosage that exceeds the regular dose a hundred times and at temperatures of over 40 degrees Celsius – the human organism is unable to handle it. Yet if the diseased organ is treated outside of the body, extreme conditions are an option. For the first time, physicians have succeeded in treating a severe case of pneumonia by using the OCS.
06/03/2018With 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.
08/02/2018When body tissue is reconnected during a tumor operation in the gastrointestinal tract, surgeons need information about the current state of these so-called anastomoses. The new, non-invasive hyperspectral imaging technology now makes it possible to measure the crucial parameters during surgery and thereby increase surgical precision.
01/02/2018During a visit to the hospital, patients naturally expect to receive comprehensive care. Not only does this include the proper treatment, but also a hospital bed and regular meals for example. Patients typically don't ask about the transport logistics this entails for the hospital.
04/01/2018The position and alignment of surgical tools in the patient’s body must always be kept in view during the operation process to guarantee success and safety. With fine sensors at the tip of the instruments and an electromagnetic signal, Fiagon's electromagnetic navigation systems accurately reproduce their position in the body.
04/01/2018Imaging, navigation, integration – these are terms that describe the modern operating room. All of these components play a key role in accurate surgical procedures. They are integrated into surgical navigation systems, which make complicated medical surgeries considerably safer.
04/01/2018While it is commonplace for operating room staff to work together as a team, the collaboration of operating room systems does not always work so well – many devices are still separated from one another, causing the OR processes to be prone to mistakes. The same applies to surgical navigation technologies that represent the interface between imaging, the surgeon and therapeutic devices.
