Design of a wound protector/retractor for thyroid surgery

Project Overview

Because of the risks of scarring, smaller incisions are being used in thyroid surgery. These small incisions still require retractors to keep the site visible, but most traditional retractors are incompatible with the smaller incisions. The currently used metal retractors distribute pressure unevenly across the incision site, which can cause ischemic trauma to the local tissues. On the other hand, our client tested round, flexible wound retractors used for abdominal surgery, and requests a similar device for thyroid surgery. The goal is to construct a device that is precise, provides a comfortable fit, and is capable of evenly distributing pressure across the site of incision.
