Decorticating device for fusing a sacroiliac joint
A decorticating device for preparing a sacroiliac joint (“SI Joint”) to receive a graft implant. The decorticating device comprises an abrading head having abrading surfaces on a first pair of opposing sides, the abrading surfaces configured for decorticating the cortical bone of the SI Joint. The abrading head further comprises a second pair of opposing sides, each side of the second pair of opposing sides comprising a curved distal portion having a curved cutting edge.
1. A decorticating device for forming a fusion implant insertion location in a sacroiliac joint, the decorticating device comprising:
an abrading head at a distal end of the decorticating device, the abrading head having:
abrading surfaces on each of a first pair of opposing sides, the abrading surfaces comprising one or more teeth, barbs, blades, ridges, slots, broaches, or other members capable of abrading a cortical bone of the sacroiliac joint; and
a second pair of opposing sides, each side of the second pair of opposing sides comprising a curved distal portion having a curved cutting edge; and
a slide hammer assembly at a proximal end of the abrading device, the slide hammer assembly having a released position that enables operation of the slide hammer assembly, a locked position that prohibits operation of the slide hammer assembly, and a releasing means for transitioning the slide hammer assembly between the locked position and the released position.
2. The decorticating device of claim 1 , wherein the abrading head further comprises a void, each of the second pair of opposing sides having an opening for enabling lateral ingress into and egress from the void.
3. The decorticating device of claim 1 , wherein each side of the first pair of opposing sides is a substantially planar member having a distal edge terminating at an open tip, an interface between the open tip and the distal edge comprising a substantially straight cutting edge.
4. The decorticating device of claim 2 , wherein each side of the first pair of opposing sides is a substantially planar member having a distal edge terminating at an open tip, an interface between the open tip and the distal edge comprising a substantially straight cutting edge.
5. The decorticating device of claim 4 , wherein the curved distal portion comprises a taper toward its opposite side of the second pair.
6. The decorticating device of claim 1 , wherein the curved distal portion comprises a taper toward its opposite side of the second pair.
7. The decorticating device of claim 6 , wherein each side of the first pair of opposing sides is a substantially planar member having a distal edge terminating at an open tip, an interface between the open tip and the distal edge comprising a substantially straight cutting edge.
8. The decorticating device of claim 3 , wherein the curved distal portion has a taper toward its opposite side of the second pair.
9. A decorticating device for forming a fusion implant insertion location in a sacroiliac joint, the abrading device comprising:
an abrading head at a distal end of the abrading device, the abrading head having:
abrading surfaces on each of a first pair of opposing sides, the abrading surfaces comprising one or more teeth, barbs, blades, ridges, slots, broaches, or other members capable of abrading a cortical bone of the sacroiliac joint; and
a second pair of opposing sides, each side of the second pair of opposing sides comprising a curved distal portion having a curved cutting edge.
10. The decorticating device of claim 9 , wherein the abrading head further comprises a void, each of the second pair of opposing sides having an opening for enabling lateral ingress into and egress from the void.
11. The decorticating device of claim 9 , wherein each side of the first pair of opposing sides is a substantially planar member having a distal edge terminating at an open tip, an interface between the open tip and the distal edge comprising a substantially straight cutting edge.
12. The decorticating device of claim 10 , wherein each side of the first pair of opposing sides is a substantially planar member having a distal edge terminating at an open tip, an interface between the open tip and the distal edge comprising a substantially straight cutting edge.
13. The decorticating device of claim 12 , wherein the curved distal portion of each side of the second pair of opposing sides comprises a taper toward its opposite side of the second pair.
14. The decorticating device of claim 9 , wherein the curved distal portion of each side of the second pair of opposing sides comprises a taper toward its opposite side of the second pair.
15. The decorticating device of claim 14 , wherein each side of the first pair of opposing sides is a substantially planar member having a distal edge terminating at an open tip, an interface between the open tip and the distal edge comprising a substantially straight cutting edge.
