Background: The Society of American Gastrointestinal Endoscopic Surgeons (SAGES) Task Force on Ergonomics conducted a subjective and objective assessment of ergonomic problems associated with laparoscopic instrument use. The goal was to assess the prevalence, causes, and consequences of operational difficulties associated with the use of laparoscopic(More)
Laparoscopic surgery may be kinder to the patient, but it is more demanding on the surgeon. Fixed trocar positions often require the surgeon to work with instruments at awkward angles to their body. We studied the effect of horizontal and vertical laparoscopic instrument working angle on the surgeon’s thumb, forearm, and shoulder muscle work.(More)
Ergonomic studies are needed to understand and improve the visual and physical interface that minimally invasive surgery methods interpose between the surgeon and the operating field. We used the Virtual Instrumentation (VI) Laboratory of the Biomedical Engineering Program at California State University, Sacramento to develop a portable ergonomic analysis(More)
Virtual instrumentation provides a strong platform for the rapid design and prototyping of biomedical instruments. Virtual instrument software written using a block diagram approach familiar to instrument designers quickly turns a personal computer into a custom biomedical instrument. The portable VIs we have developed for ergonomic analysis of(More)
