... characteristics promote fail-safe malfunctions, including locking before catastrophic failure and a decreased likelihood in detached parts. Initial benchtop testing shows good agreement between prototype performance and model prediction. Frictional losses experienced during testing were found to depend on load...

... of cutting is performed by steel wire that runs through the center of rotation of the instrument joint. A prototype of the concept was fabricated and evaluated technically. The prototype demonstrated a range of motion between −22° and 25° with a steering stiffness of 17.6 Nmm/rad (min 16.9 – max 18.2 Nmm/rad...

...). This paper describes a 6-DOF steerable laparoscopic grasping forceps incorporating a novel and very simple “cable-ring” mechanism consisting out of a ring of cables surrounded by two coil springs. Methods are described to increase stiffness and to improve manual control, resulting in a well-working prototype...

...Stacy L. Figueredo; Alexander H. Slocum In order to test small scale medical devices, it is often necessary to prototype them on a larger scale such that proof-of-concept tests can be made more affordably and design details can be tested more easily. This article discusses a method of scaling large...

...Ryan K. Buesseler; David B. Hom; Arthur G. Erdman 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...
