This paper presents the design and prototyping of a novel stapling device and method intended for—though not limited to—the nasal septal mucosa. The pistol shaped device has two long projections: one for each nostril. The internal mechanism pushes the male portion of the rivet, nearly 10 cm down one tube, where it pierces the mucosa and mates with the female portion. This is all accomplished with one grip of the handle, rotating the input handle only 30 deg. The internal mechanism was designed by solving loop equations for a five-bar, dual-slider single degree-of-freedom mechanism. Components were then rapid prototyped before the eventual functional prototype was completed.
