Abstract
A surgical tool and method are provided for positioning an intervertebral device between vertebral members. The tool includes an elongate shaft, an anti-rotation sleeve, and an actuation mechanism. The shaft has proximal and distal ends, with the distal end of the shaft including an engagement member for releasably engaging an intervertebral device. The sleeve includes proximal and distal ends, and is movably mounted to the shaft for reciprocating relative thereto between retracted and extended positions. The distal end of the sleeve includes an anti-rotation member. The actuation mechanism controls positioning of the sleeve between the retracted and extended positions, and locks the sleeve relative to the shaft. When the intervertebral device is releasably engaged by the engagement member, and the sleeve is in the extended position, the anti-rotation member engages the intervertebral device and prevents rotation of the intervertebral device when releasing the engagement member from the intervertebral device.
