ABSTRACT:
A method and tool provided with irrigation for transection of a band, ring or the like and method of use is disclosed which includes a power-driven drill operable for driving a rotatable shaft which rotates a circular cutting blade mounted on the shaft, and a head assembly mounted on the drill includes a port structure oriented for transferring irrigation fluid from a source onto the ring or band to provide cooling to the ring or band and cooling to the cutting blade during cutting action. The transfer of irrigation fluid also facilitates removal of metallic filings or debris caused by the cutting action and irrigating a traumatized area adjacent the ring or band. The port structure is dimensioned with a bore for receiving a tubular member connected to the source, which delivers fluid to the port structure, which has an axis aligned substantially parallel to a planar surface of the cutting blade.
