Above are renderings of the final devices. The results of the project where strong improvements in aesthetics, modest improvements in ergonomics but little improvement in the overall functionality of the the system.
The original devices are shown above. Specific ergonomic and compatibility issues where targeted and addressed.
Some thumbnails exploring different ways of eliminating the discomfort experienced when gripping the "open" side of the handle.
Form exploration...
Many quick foam and clay models where created to consider alternate actuator configurations for the bipolar device. Two of the concepts were selected for prototyping and more in-depth evaluation...
The dissector/retractor and the bipolar prototypes where shown to 20 preceptors. A protocol was used to gather feedback and narrow the design team's focus. This research allowed the design team to select a final design direction.
