How do you design an endoscope tool for a dolphin?

My team worked with a local aquarium to design a tool to clean endoscopes while still inside the marine mammal.

We prototyped a tool that utilizes a wiping motion to clean an endoscope camera lens of biomaterials.

The tool is comprised of a 3D printed handle, Asahi torque transmission wire, a shape-changing NiTi cleaning head, and a heating circuit.

The biocompatible tool safely operated inside a 2mm wide working channel 3m long.

My main role on the team was CAD and rapid prototyping to create multiple prototype iterations.
