Abstract
Bearing assemblies for selectively coupling to surgical instruments A bearing assembly can include a housing with a cavity, a first race in the cavity that translates but does not rotate relative to the housing, bearing elements disposed in the first race that move radially in and out of a central passage of the first race, and a second race that is fixed in the cavity. The first race can be biased toward an opening of the cavity, the second race can surround the first race with an inner surface having a tapered diameter configured to contact the bearing elements as the first race moves distally relative to the second race and urge the plurality of bearing elements radially inward to selectively lock the bearing assembly to a surgical instrument disposed within the central passage of the first race.
