Senior Design Capstone Project: Multi-Use Laparoscopic Stapler

My capstone project focused on improving a system for Medtronic’s Signia Stapler, where we work directly with two Medtronic engineers who guide requirements and design direction. This project was heavily early R&D focused.

I served as the CAD engineer on a team of seven, where I managed all CAD organization through a BILD, PDM system and lead design work in SOLIDWORKS, with a strong focus on design for manufacturability. I collaborated closely with our manufacturing and systems engineers to ensure our designs integrate well and can be efficiently produced.

One of the biggest challenges has been working in a fast-paced, sprint-based environment with three-week design cycles. We often had to design, prototype, and test within a very tight timeline. That and the size constraint. Since this is supposed to fit in a 12 mm trocar, we scaled our final prototype up to 300% for feasibility when manufacturing these components in house.

To handle that, I was very intentional about planning ahead, prioritizing critical design features, and quickly iterating based on feedback from both testing and our Medtronic clients. I personally contributed to the material and structural makeup of the transportation system as well as assisted and led a few test cases using DFMEA and PRS tables.

As result of my team and I’s hard work, we have been named as inventors on Medtronic’s provisional.
