The veterinarian at the University of Illinois uses 3D printing to help the eagle return to the blue sky
The impact of 3D printing technology on the medical industry is undeniable. From pre-operative preparation to patient-tailored prostheses, it has become a viable technical solution for more and more healthcare-related applications. This influence continues to extend beyond human health care and serves a wide range of other species, especially those with wings and feathers. In this year, we saw Duck Phillip receive a new 3D printed foot, the technician rescued a Chinese parrot with a fake scorpion, and a Brazilian parrot received the world's first titanium enamel substitute. .
It seems that 3D printing technology can help veterinarians prepare for surgery for one of the world's most precious birds. Recently, students from the University of Illinois College of Veterinary Medicine met a wild eagle. The eagle suffered a gunshot wound a few months ago and was not properly cured, so its left tibia was not aligned. In order to help the bird fly again, an intensive surgery is needed. To this end, students from the College of Veterinary Medicine asked the engineering students for assistance in creating two 3D printed 1:1 eagle humeral models, one for the healthy tibia and the other for the actual injured bone.
Before the famous bird surgeon R. Avery Bennett used the 3D printed model, veterinary radiologist Stephen Joslyn obtained a huge data packet through a spiral CT scan to assist with the operation. After consulting with Australia, Joslyn added a so-called "threshold value" to the data to enable the computer to distinguish between "bone" and "non-bone" from subtle scan information. Because the injured bones were broken into pieces and could not be printed together, medical draftsman Janet Sinn-Hanlon used software to manually thicken and connect the bone regions together.
Driven by experts from the Wildlife Clinic clinical practice and Dr. Nichole Rosenhagen of the University of Illinois, 1:1-sized models were printed in 3D at the university's rapid prototyping lab. However, on the day before the surgical plan, the lab had a 3D print queue full. With the help of Mechanical Science and Engineering, technical services director and laboratory manager Ralf M ö ller, the model within 6 hours to print out the same night, just in time for the next morning to open the door of the lab time.
M ö ller received help students lab technician Nick Ragano, he stayed all night to ensure that the laboratory will be ready 3D models, and pressure washer for starch-based plastic scaffolds print model. On the morning of May 5, the 3D printed bones were sent to Dr. Rosenhagen. The eagle injured in about 3 hours successfully underwent orthopedic surgery.
With 3D printing technology and the concerted efforts of students and experts at the University of Illinois, the eagle is hopeful to re-emerge in the sky in the near future.
