Abstract: A device for drilling a hole in bone and for inserting bone screws into the drilled hole is provided. The device comprises a trocar, drill sleeve and protection sleeve in a telescopically nested configuration. The drill sleeve and protection sleeve may have an axial locking feature that allows the two pieces to be handled together as a unit by preventing inadvertent separation. The axial locking feature may comprise an integral annular ridge provided on one sleeve that cooperates with an annular groove provided on the other sleeve. One sleeve may also have at least one slot allowing the locking feature to be disengaged prior to separation of the sleeves. The sleeves may be easily separated with one hand by the user by the application of an axial separation force between a pair of flanges provided with the sleeves, and by a radial compression force applied to at least a portion of the drill sleeve.
