Abstract
A cylindrical sleeve device can be attached or secured to a surgical drill. The sleeve can include a drill coupler, an intermediary section, and a sleeve body. The sleeve can include multiple internal channels. The internal channels can include drill channel, which can be circular and located at the center of the sleeve. The drill channel can be configured to receive a surgical drill. The internal channels can include a suction channel and/or a cooling channel. The suction channel and/or cooling channel can be concentrically positioned relative the drill channel.
