The integrated deviation in the HUESAD (Hiroshima University Endoscopic Surgical Assessment Device) represents the surgeon's visual-spatial ability

摘要

This institution developed the Hiroshima University Endoscopic Surgical Assessment Device (HUESAD). HUESAD is a reliable system for objectively assessing a surgeon's skill on the basis of the direction and movement of laparoscopic long instruments. Previous studies calculated the integrated deviation, the peak velocity and the approach time from the HUESAD. However, what these three dexterity parameters (the integrated deviation, the peak velocity, the approaching time) in the HUESAD represent concerning the surgeons' ability remain unclear. The purpose of this study was to determine whether the three dexterity parameters in the HUESAD are associated with the surgeon's visual-spatial ability.
