Octopuses have eight arms that are perfect for gripping rocks, catching prey, and walking along different surfaces. They do this with the suction cups that underline their arms. We are currently developing soft suction cups for stable needle insertion in flexible tissue inspired by these octopus suction cups.
Tissue motion and deformation leads to needle positioning errors. Hence, clinicians typically needle multiple attempts to position the needle at the target location. To achieve accurate needle positioning, clinicians can stabilize the tissue by gripping it. However, gripping and handling of slippery and flexible tissues during minimally invasive surgery is often challenging. Current grippers commonly use a force grip to manipulate tissue, which makes it prone to damage. Octopus-inspired suction cups integrated with a needle could be the solution that stabilizes tissue during needle insertion without damaging the tissue.
This MSc-graduation project involves designing, developing, and testing a novel stable-needle insertion device that allows for accurate needle positioning. We are searching for a student that is interested in a design-oriented project. For this project, SolidWorks, 3D-printing, and creative-problem-solving skills are useful.
