Masaryk University launches anatomical model database

The 3D printing laboratory, operating within the Simulation Centre of the Faculty of Medicine at Masaryk University (SIMU), has contributed to the development of 3D printing in medicine by launching a portal with a collection of anatomical models of bones, organs, and educational simulators.

“Unlike other similar platforms, which usually operate on a commercial basis, our portal is publicly and freely accessible. Each model also comes with a methodology, so anyone can download and print it themselves,” said Jiří Travěnec, Deputy Director for Technology at SIMU.

Compared to other platforms – often completely unmoderated – the models available on the platform have one crucial distinguishing feature: each has a professional guarantor responsible for its anatomical accuracy. In fact, it is often these guarantors, typically educators or practicing clinicians, who help shape the database through their specific requests. “For example, a guarantor may request a model of the large intestine to practice laparoscopic suturing. Based on CT scans or using 3D scanning, we technicians produce the model, and the guarantor then verifies not only its visual accuracy but also its suitability for the intended purpose,” said Travěnec.

Producing educational tools in-house has numerous benefits – from self-sufficiency and logistics (eliminating the need for large stockpiles) to sustainability. In simulation-based education, where teaching aids are naturally subject to high wear and tear, 3D printing also offers significant financial savings. “There was a case where a supplier offered us a cannulation simulator for the umbilical cord that was unsuitable for teaching purposes. So, we developed our own. Moreover, we can produce some simulators at just a fraction of their typical cost,” said Travěnec, noting that certain types of materials can even be recycled after use and repurposed to create new models.

Currently, the collection contains seventy models, which was the target set by the project, and Travěnec and his colleagues have more in stock. He is also optimistic that the database will continue to grow along with the expansion of the 3D printing community in medicine, not only in the Czech Republic but also abroad.

As it turns out, what began as an initiative by a few enthusiasts is now gaining recognition among clinicians as well. At SIMU, they are setting an example through collaboration with colleagues from the First Department of Surgery of St. Anne’s University Hospital. Together, they are developing a project focused on fractures of the tibia and clavicle. “Based on CT scans, we can print a bone using a mirrored image of the healthy side, allowing surgeons to pre-plan the operation – decide where to attach titanium plates and screws, test where to drill into the bone, or model a custom plate,” said Michal Šemora, Technician at SIMU. “We’re able to process such a request from the hospital by the next day.”
