A Fully 3D-Printed Steerable Instrument for Minimally Invasive Surgery

In the field of medical instruments, additive manufacturing allows for a drastic reduction in the number of components while improving the functionalities of the final design. In addition, modifications for users’ needs or specific procedures become possible by enabling the production of single customized items. In this work, we present the...

Steerable Neuroendoscopic Biopsy Forceps: Expanding the reach

Objective: To develop a steerable neuroendoscopic instrument (SNI) based on user requirements found by several means of user research, and to evaluate this instrument on usability and safety. Only 5% of the potential intraventricular neuroendoscopy (INE) cases are currently treated with endoscopy. For the other 95%, an endoscopic approach is...

Design and stepwise user evaluation of an ergonomic 2 DOF arthroscopic cutter

The goal of this study was to determine the preferred handle design for two degrees of freedom steerable arthroscopic cutter by performing a two-step development approach. The expected usefulness and usability of control components of three entirely different handles were defined by an on-line survey with 101 students and the actual control...
