Abstract: In one embodiment, a quick connect interface for a surgical instrument includes a body having an outer surface and an inner surface that defines an inner cavity. One or more ball bearings are disposed in respective holes in the body. A locking pin is disposed on a ramp formed in the body. A sleeve surrounds a portion of the body and is slideable along the body, from an unlocked position to a locked position. The sleeve includes a camming ramp that urges the one or more ball bearings to partially extend through the holes into the inner cavity. One or more springs are arranged to urge the locking pin down the ramp, so that the locking pin partially extends through an opening into the inner cavity. The one or more ball bearings and the locking pin are positioned to urge the shaft to one side of the inner cavity.

Abstract: In one embodiment, a quick connect interface for a surgical instrument includes a body having an inner cavity that includes a flat. Two or more ball bearings are each disposed in a respective hole in the body. A sleeve is slideable along the body. The sleeve includes a camming ramp that urges the two one or more ball bearings to partially extend through the holes into the inner cavity when the sleeve is in a locked position. The two or more ball bearings are positioned to, when the shaft of the replaceable tool is disposed in the inner cavity, urge the shaft to a side of the inner cavity that includes the flat. The ball bearings may be positioned radially about a central axis of the body substantially 90 degrees apart. The camming ramp may include at least one plateau that prevents unintentional release of the shaft.
