The goal of this project was to design, prototype, and test scalpel handles for small lesion removal. Scalpels are one of the most extensively used surgical tools in medicine today. However, the current flat-sided design limits the surgeons' ability to create precise, small incisions because the scalpel handle tends to rotate in their hands, especially for nonlinear incisions. To overcome this problem, we designed an ergonomic scalpel handle which features a cylindrical cross-section and smooth tapering that naturally fits hand positions which are used for creating an incision. Specifically, the scalpel handle was designed to increase the comfort, control, and precision a surgeon has during surgery.
