As of 2019, one out of eleven people in the world is over
the age of 65, and the ratio will increase to one in six by
2050*. Aging is one of the most important demographic
changes in the twenty-first century, and its implications
for the medical industry are significant and profound.
“Major OECD member states are experiencing an
explosive increase in medical expenses, as they enter
the phase of aging. Applying 3D printing technologies
to various medical fields not only enables customised
medical instruments, but also reduces medical costs,”
states Prof. Kim Nam-guk from the Department of
Convergence Medicine at Asan Medical Centre.
Founded in 1986, Asan Medical Centre is the largest medical institution in Korea with a total of 2,705 beds occupying about 85,000 square metres. It has been leading Korea’s medical development by offering world-class medical professionals and optimal treatment systems — based on advanced medical systems — as well as cutting-edge medical equipment. As the Korean society ages, Asan Medical Centre also needs to treat more patients with serious diseases.
Surgeons often find it necessary to establish surgical plans, perform simulation operations and explain the surgical procedures to patients. However, mere CT and MRI data were not tangible enough. They want a detailed surgical site, which could show the locations of blood vessels with clarity. As the cradle for medical innovation, Asan Medical Centre introduced 3D printers from Stratasys in 2013 to address these issues. The Department of Convergence Medicine, the Department of Radiology and the Department of Surgery have worked on a project to increase the accuracy of tumor surgery for kidney cancer and breast cancer. Recently, Asan Medical Centre’s 3D printing technology has been selected as a “new medical technology” by the Ministry of Health and Welfare for the first time in Korea.
What Is Being Done
Surgeries for kidney cancer often involve the excision of the patient’s kidney, either complete or partial. It makes more sense to only remove the part of kidney that has been affected by the cancer cells, but the operation requires great precision. Important blood vessels must not be touched. 3D printing provides a great solution to this conundrum. With Connex3, doctors at Asan Medical Centre can print organ models that are both soft and transparent. Because the materials are soft, the doctors can perform mock surgeries on the models. And because they are transparent, the insides, such as renal arteries and veins, the renal pelvis, tumor issues, etc., are easily visible to the naked eye. The 3D printed models have greatly contributed to the precision and speed of operations. Breast cancer surgeries can also benefit a lot from 3D printing technologies. Before the surgery, a microneedle typically needs be inserted into the breast under ultrasonography in order to mark the surgical site. This difficult procedure requires an expert surgeon and often brings pain to the patient. At Asan Medical Centre, surgeons 3D print customised surgical guides based on the patient’s MRI data before each operation. Made with Stratasys’ FDM technology, these guides are sturdy and can mark the surgical sites accurately without bringing unnecessary pain to the patient. At the same time, surgeons can preserve the normal breast tissues to the largest extent and reduce the revision and relapse rates.
