Abstract
A surgical instrument for use with a break-off device including a proximal portion removably attached to a distal portion by a region of reduced strength to allow selective removal of the proximal portion from the distal portion. The surgical instrument includes an inner drive shaft extending generally along a longitudinal axis and having a distal end portion engaged with the proximal portion of the break-off device, and an outer retention sleeve positioned about the drive shaft and including a distal receiver portion engaged about the proximal portion of the break-off device. A force applied to the proximal portion of the break-off device by the drive shaft causes the break-off device to fracture at the region of reduced strength to separate the proximal portion from the distal portion, with the proximal portion maintained in engagement with the surgical instrument by the retention sleeve.
