Claim of US Patent No. 10,363,026

1. A top locking rotatable suture anchor device for orthopedic surgical procedures to attach soft tissue to a bone using one or more sutures providing adjustment of an angle of tension and rotation of an attached suture prior to, during and subsequent to installation in a bone, said rotatable suture anchor device comprising:an anchor body defining an upper end, a lower end with a longitudinal axis there between, said body further defining an outer surface providing a plurality of bone securing projections, an inner longitudinal chamber along said longitudinal axis defining an inner wall providing at least one circumferential inner locking groove, and an upper chamber expansion;
a central pin disposed within said inner longitudinal chamber defining a base, an upward extending cylindrical slide shaft having an upper end with an annular space provided between said cylindrical slide shaft and said inner wall of said inner longitudinal chamber;
an eyelet pin defining a proximal end, a distal end, an inner bore having a lower bore opening, said inner bore slidably and rotatably engaging said cylindrical slide shaft within said annular space into an open position and a closed position, said eyelet pin further defining an outer surface extending at least one pin lock extension to lock said eyelet pin within said at least one circumferential inner locking groove into said closed position, and a transverse passage defined within an upper lock expansion at said proximal end receiving at least one suture through said transverse passage; and
a rotatable ring defining an inner opening, an upper end, a lower end, an outer surface and a ring lock groove, said rotatable ring installed within said upper chamber expansion, said rotatable ring remaining fully rotatable about said longitudinal axis while longitudinally secured, said proximal end of said eyelet pin longitudinally moveable within said rotatable ring between said open and closed position, wherein said at least one suture is secured within said suture anchor device in said closed position within said transverse passage at a desired length and tension, with or without requiring a knot or tied connection to said suture anchor device, said at least one suture engaged between said proximal end of said eyelet pin and said inner surface of said rotatable ring, wherein said suture attachment may be knotless, knotted or tied to said suture anchor device, while still providing said suture fully rotatable around said longitudinal axis relative to the anchor body in said closed position.
