Abstract
A handle releasably attaches to a surgical instrument. The handle permits a physician to fit a selected instrument to the handle tactilely, without need of visual confirmation. At the same time, the handle makes possible the reliable transmission, with increased mechanical advantage, of both torsional and longitudinal loads by the physician to the selected instrument. The handle also permits quick detachment of the selected instrument from the handle, without sticking or inordinate force.
