Patent number: 12150684Abstract: In one embodiment, a bone screw includes a shaft having a proximal shaft end and a distal shaft end spaced from the proximal shaft end in a distal direction along a central axis. The shaft is helically threaded between the proximal and distal shaft ends. A tip extends from the distal shaft end in the distal direction, and defines a plurality of lands with cutting flutes disposed between adjacent lands. Each land has a bore-cutting edge that extends from an inner cutting edge end to an outer cutting edge end. The inner cutting edge end is disposed at a center of the distal end of the tip, and the outer cutting edge end is spaced from the center of the distal end of the tip. The bore-cutting edges may blunt the feel of the tip so as to reduce the likelihood of soft-tissue damage.Type: GrantFiled: May 6, 2021Date of Patent: November 26, 2024Assignee: DePuy Synthes Products, Inc.Inventor: Joel Patrick Bales
