Abstract/Artist Statement
Canine prosthetics currently on the market consist of only static leg movements with limited mobility due to their pylon design. This project aims to construct a prosthetic for a canine, Phoenix, who is a monopolegic following a vehicle accident. The components of the prosthetic include (1) 3D printed front leg and vest, (2) adjustable fabric vest for comfortability, distribution of weight, and forces exerted, (3) elbow joint movement via the use of a hydraulic shock, and (4) medical grade pediatric prosthetic pyramid adapter to securely attach the limb to the 3D printed vest. The addition of an elbow joint using a hydraulic shock will provide for a more dynamic prosthetic that mimics the nature of a healthy dog limb, allowing for a greater range of motion and the navigation of various terrains all while limiting the impact to muscles and joints that a static prosthetic inflicts. The evaluation and verification of our design is completed through the use of force plates and biomechanical calculations. With the raw data gathered from the force plates, we can assess and visualize how much force is applied on her healthy limb, ideally 60% of weight without the prosthetic has been on her healthy limb, so our goal with our data is to observe about 30% force being equally distributed between prosthetic and healthy limb as Phoenix performs her natural gait cycle. Following the raw data, biomechanical calculations were completed to determine the percentage of how much she relies on her front legs. These calculations were then used to compare against our data and determine whether our design meets the user needs and requirements set, as well as to determine the distribution of weight that our prosthetic limb relieves.
