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.
15/09/2021Precise, extremely quick and accurate – a new kind of navigation device in the OR uses a highly-developed camera technology to guide the surgeon through difficult procedures – directly in the OR. Prof. Ulf Liljenqvist, Chief Medical Director of the Clinic for Spinal Surgery at the St. Franziskus Hospital Münster, talks about his experiences in using the device.
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.
23/08/2021We cannot heal Parkinson’s disease yet, all we can do is alleviate the symptoms. One possibility to do this are implantable electrodes that stimulate part of the brain and counteract the characteristic tremor. In our video, Prof. Cordula Matthies and Prof. Jens Volkmann from the University Hospital Würzburg explain how this stimulation can be targeted better with a new electrode generation.
20/08/2021A team of engineers and physicians has developed a steerable catheter that for the first time will give neurosurgeons the ability to steer the device in any direction they want while navigating the brain's arteries and blood vessels. The device was inspired by nature, specifically insect legs and flagella – tail-like structures that allow microscopic organisms such as bacteria to swim.
09/08/2021The Southwest Research Institute and The University of Texas at San Antonio are collaborating to create a computer model of the intricate structures of the human heart as part of a larger effort to develop a new, potentially life-saving heart surgery.
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.
02/08/2021Surgical intervention is often inevitable when blood vessels become narrowed, blocked, or damaged. Surgeons use stents and medical balloons to open and widen the arteries, suck out the obstructing clots and use a catheter to examine the vessels. Intraoperative cardiovascular imaging is an essential tool to guide the catheters and instruments during the minimally invasive procedures.
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.
01/04/2021Surgeons 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.
01/04/2021For 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.
01/04/2021The 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.
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.
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.
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.
04/05/2020Robotic 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.
04/05/2020Surgical 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.
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.
09/03/2020Treatment 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.
10/02/2020If 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.
03/02/2020Regenerative 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.
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.
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.
04/11/2019Since its inception, MEDICA TECH FORUM has focused on the implementation of innovations and new technologies into clinical practice. 2019 marks the tenth year of the Forum. In honor of its anniversary, we will brighten things up a bit, as one of the focal points will highlight how optical coherence tomography (OCT) uses light to produce images.
22/08/2019The German Medical Award will take place on November 18, 2019, as part of the MEDICA trade fair in Düsseldorf. The ceremony emphasizes the commitment to excellence in cutting-edge care for patients. Doctors, clinical centers and companies in the medical and healthcare industry can demonstrate their achievements in medicine and management in hopes of receiving the coveted award.
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.
08/03/2019Orthopedic implants – they are a necessity when it comes to congenital or acquired limb length discrepancies. However, full weight-bearing during the limb lengthening process is not feasible with previous implant models. For the first time, the 3D Surgery division at the Medical Center of the University of Munich has succeeded in using an implant that facilitates immediate weight-bearing.
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.
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.
01/02/2018Hospitals need an accurate assessment of the location and quantity of their materials to eliminate sources of error. Automated processes can also help employees to make these materials available at the right time and at the right place. Digital network systems will substantially support the logistics in the hospital of the future.
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.
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.
