Ergonomic Evaluation of a Prototype Console for Robotic Surgeries via Simulations with Digital Human Manikins

• Work-related musculoskeletal disorders impact surgical performance, which increase risks for patient safety. A new console has been designed to reduce workload for robotic surgery surgeons. Due to high costs and long waiting time of the production process, a pre-production ergonomic evaluation of the new design is preferable. In this paper, we evaluate if the new console at the pre-production stage by using an US checklist, and the Swedish standard for visual display unit work. A 3D model of the new designed console was introduced to the virtual environment of a digital manikin (Intelligently Moving Manikin, IMMA). The work-ranges of the console were calculated. Various individual work distances of 12 manikins (3 men and 3 women per each of the US and the Swedish population) were “measured”. The data were integrated and used as an objective reference to compare with the Swedish standard, and the US checklist. The result shows that the criteria in the Swedish standard and the US checklist are fulfilled, except for those are related to the adjustable range of the screen view height, the height range of the armrest and the adjustable distance of the pedals. The new console fulfills most of the criteria in the checklist and the standard, but there is room for a few improvements. The DHM tool IMMA provides the possibility for a pre-production assessment. However, the limited virtual measurement tools of IMMA restrained the time efficiency of the ergonomic assessment.
