![]() ![]() Schwenke developed this process, student doctors had to rely on visualizing these complex models primarily in their heads or with 2D representations. And once printing starts, they’re free to continue seeing patients.īefore Dr. “These models are extremely valuable to student doctors so that they can better understand how the blood flows through the arteries that connect the neck and the brain,” says Dr. Schwenke and his team are able to learn more about patient aneurisms. While preparing models for 3D printing, Dr. The time spent producing these scale models is not time wasted, it’s time learning. “The models help ease patient anxiety,” he explains, noting that patients feel more confident and comfortable as he demystifies each part of the process. The physical models also help him visualize his patients’ anatomy and inform patients about their upcoming procedures. This process minimizes the risks that come with complex brain surgery and saves time, enabling the team to see more patients. From Fusion 360, the data then becomes a physical, 3D printed scale model of the artery that the team can analyze and even run a fluid dynamic simulation on. Then, they carry the data over to Fusion 360 where they design mechanical interfaces. Schwenke and his team process and prep the data in Netfabb. He started using Netfabb, Fusion 360, and Formlabs SLA hardware about five years ago to create simple brain artery prints using the isolated data.įirst, Dr. Schwenke can isolate a relevant artery through a combination of CT scans and 3D rotational angiography (or 3DRA). The skull does not have to be opened.” From molecules to scale modelĭr. “We then access the brain through these approaches with catheters. “The aneurysm surgeries that we do are minimally invasive endovascular procedures through the inguinal arteries or the wrist arteries, all under fluoroscopy,” he explains. The 3D models help them visualize the situation at hand so they can begin the surgeries with as much prior knowledge as possible. Essentially, they 3D print their patients’ brain arteries to prepare for upcoming surgeries. Thanks to 3D printing technology, he and his team at the University Hospital Schleswig-Holstein in Lübeckcon have been able to improve the quality of operations performed on brain aneurysms. Schwenke is a pioneer in the neurosurgeon field. Hannes Schwenke uses 3D printing in conjunction with scanning to produce accurate models of patient organs to treat them more effectively.ĭr. A prime example of this exciting new reality is how Dr. Ten years ago, you wouldn’t have believed us if we told you that 3D printing would eventually become affordable enough for doctors to use in their daily practices. Learn more about their process in this article. ![]() Hannes Schwenke and his team are 3D printing artery models to get a closer look at patient anatomy and ease patient anxiety. ![]()
