Students from Auburn University’s veterinary and engineering programs collaborated to create a 3D-printed laryngoscope aimed at improving the teaching of intubation procedures for goats and pigs. Due to the small mouth and airway of goats, intubating these animals can be particularly challenging, a concern for veterinary students during practical training sessions. To tackle this issue, the large-animal anesthesia team at the Auburn University College of Veterinary Medicine partnered with the Samuel Ginn College of Engineering to design an affordable laryngoscope equipped with a camera that displays the intubation process in real time.

Katie Ray, LVT, who has taught numerous veterinary students how to perform large-animal intubations using traditional metal laryngoscopes, initially recognized a gap in available veterinary equipment for ruminants. While video laryngoscopes have enhanced visibility in human medicine, no equivalent existed for veterinary use. In an effort to improve training, Ray used a low-cost borescope camera connected to her phone, allowing students a clearer view of the procedure through a traditional laryngoscope.
Inspired by the positive results, Nassim Bouhabib, DVM, joined the team to integrate the camera directly with the laryngoscope, prompting further collaboration with the engineering department to refine the tool. Mechanical engineering students Will Jones and Cooper Rice from the Mechanical Polymer Additive Manufacturing (ME3D) Laboratory worked with the veterinary team to develop multiple 3D-printed prototypes.
Jones expressed that this experience was valuable, giving them insights into real-world applications of their education. Through various iterations and feedback sessions, the team created a final product that consolidates advancements from engineering and veterinary medicine.
The completed laryngoscope features a lever-controlled camera for angle adjustment, a large display screen for real-time viewing, and a blade that can adapt to different animal sizes. While effective for actual procedures, Ray believes the device serves a greater purpose in education, particularly for students who are new to working with larger animals.
The device allows students to visualize the intubation process rather than relying solely on verbal explanations. Ray points out the device’s potential as an educational tool for visual learners.
The research team has submitted a paper for publication that will include the 3D printing files needed for the device’s replication. Once published, this will allow veterinary practitioners to create their own versions. Ray noted the significance of involving veterinary technicians in research and innovation through projects like this, highlighting the collaboration between veterinarians and technicians.
This project illustrates the innovative spirit within Auburn's veterinary and engineering programs, showcasing the potential for future developments in veterinary technology.
