Intra-Operative Rotational Guide

Abstract

The engineering team at AVACETM Biomedics has developed a medical device concept that would assist in verifying bone segment placement and realignment—intraoperatively—during a bone deformity correction. The concept is centered around a circular bubble or spirit level designed to attach and detach to the orthopedic surgical pins that are typically placed on the bone during a correction surgery. The device is developed for intraoperative use and makes effective use of existing hardware to help guide the orthopedic surgeon and their team during deformity corrective surgeries. Current methods of determining and checking bone placement are limited to visual estimation. The ability to verify the placement via direct measuring would decrease the degrees of misalignment, reduce the need for further interventions, as well as mitigate any potential health complications. The market this device would be entering is that of the global skeletal deformation correction. This market is valued at 6 billion dollars with a compound annual growth rate (CAGR) from 2024 to 2033 of 5.54%. The diameter of the pins provided to our team is 2 mm and we designed our concept around this specification. The dimensions of the device are 2 x 4 x 2 inches and it will weigh slightly less than 0.5 pounds. It will also be easy to use and sterilizable for multiple uses. The design for manufacturing the product involves using ethanol, yellow-5 dye, rubber o-rings, and a 3D-printed plastic container to assemble the physical device. The estimated cost to manufacture a single unit is approximately $112.67 plus tax.
