  • Patent number: 5569256
    Abstract: A surgical resection tool of the type having a rotary motor, a dissecting tool and a bearing tube is provided with dual quick releases for quickly releasing and latching dissecting tools and bearing tubes to expedite tooling changes during surgical procedures. The surgical resection tool preferably has a canted centerline in which the centerline for the rotary motor is canted with respect to the centerline for the dissecting tool and the bearing tube to provide an ergonomic shape for holding the resection tool. In a preferred embodiment, the two quick releases are provided by collet type latches having latching balls and slidable sleeves. The slidable sleeves are coupled together for selectively moving to a latching position where latching balls are pressed into grooves formed into dissecting tools and bearing tubes to latch a dissecting tool and a bearing tube into the resection tool.
