Square quick connect interface

摘要

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.

主权项

1. A quick connect interface for a surgical instrument, comprising:
a body having an outer surface, and having an inner surface which defines an inner cavity that is shaped to accommodate a shaft of a replaceable tool; one or more ball bearings that are each disposed in a respective hole in the body that extends from the outer surface to the inner surface of the body; a substantially cylindrical locking pin that is disposed on a ramp formed in the outer surface of the body, the ramp having an opening that extends from the outer surface to the inner surface of the body; a sleeve that surrounds a portion of the body and is slideable along the body, from an unlocked position to a locked position, the sleeve including a camming ramp that contacts the one or more ball bearings, the camming ramp arranged to urge the one or more ball bearings to partially extend through the holes into the inner cavity when the sleeve is in the locked position; one or more springs arranged to urge the substantially cylindrical locking pin down the ramp formed in the outer surface of the body, so that a side of the substantially cylindrical locking pin partially extends through the opening into the inner cavity when the sleeve is in the locked position, wherein the one or more ball bearings and the substantially cylindrical locking pin are positioned such that, when the shaft of the replaceable tool is disposed in the inner cavity, the one or more ball bearings and the side of the substantially cylindrical locking pin will contact the shaft and urge the shaft to one side of the inner cavity.
