A rotary cutting tool including an elongated housing having a proximal end and a distal end, the elongated housing extends circumferentially around a first axis. A drive shaft disposed within the elongated housing and extending between the proximal end and the distal end and rotatable about the first axis. A cutting bit housing coupled to the distal end of the elongated housing and rotatable relative to the drive shaft about an articulation axis between a non-articulated position and one or more articulated positions. A rotary cutting bit coupled to the cutting bit housing and the drive shaft and rotatable about the articulation axis with the cutting bit housing, the rotary cutting bit and drive shaft forming a constant velocity joint.

Articulating rotary cutting tool

Surgical tool cutting bit

An articulating rotary cutting tool configured to articulate a distal cutting tip upon a trigger being operated. The trigger can be locked into various articulating positions. The velocity of rotation of a cutting bit is substantially constant in both articulating and non-articulating positions. An articulation joint is one of a hex ball joint or a flexible spring joint. A button is included to release a locking pressure holding the trigger in a locked position. The trigger may employ articulating sliding surfaces that provide constraint to a flexed head in both directions of articulation.
