Abstract
A bearing system is provide to couple a tool shaft to a power driven surgical instrument that has a support tube with a longitudinally extending aperture for rotation of the tool shaft about an axis. A pair of bearing assemblies are spaced apart within the aperture by a sleeve and a helical spring that axially biases the bearing assemblies within the aperture. Each bearing assembly includes first and second bearings and an interface cartridge. The first bearing has an outer race abutting a flange element in the aperture, and has an inner race. The tubular interface cartridge engages the inner race and has spring elements extending radially into a passage through the interface cartridge to engage the shaft. A second bearing has an inner race abutting the tubular interface cartridge and has an outer race against which force from the spring is applied.
