Abstract/Summary
The PolyHIPS team was tasked with integrating sensors into Stryker’s hip arthroscopy boot that monitor blood flow and heel slip during hip surgery. During hip arthroscopy, the femur head is distracted from the acetabulum to create space in the joint for the surgeon to operate. This requires the use of up to 200 lbf. In order to maintain this space, the foot is held tightly in the boot. Complications can result from the foot being held too tightly in the boot during the procedure. The most common complication is neuropraxia, or temporary nerve damage. PolyHIPS proposes a solution that utilizes three types of sensors to monitor for nerve damage and heel slip. The final design includes three pressure sensors and a distance sensor that are all wired to a microcontroller. The microcontroller displays the sensor data on an LCD screen and transmits the data via Bluetooth to an app.
