The embodiments herein relate generally to systems to close and heal wounds.
Prior to embodiments of the disclosed invention retention suture assemblies had holes that were perpendicular to the plane of the plates. Some examples of this are shown in U.S. Pat. No. 4,210,148 issued to Stivala, U.S. Pat. No. 6,120,525 issued to Westcott, and U.S. Pat. No. 5,127,412 issued to Cosmetto. Of those, Stivala is the most widely used and is described in
The suture 11 creates two sets of forces. A closure force 12, 13 is shown pushing a first edge 14 of wound W toward a second edge 15 of wound W. The closure force 12, 13, shown in the x-direction is a good thing. However, a tearing force 16, 17 causes the suture 11 to tear through the skin S causing significant scaring. The tearing force 16, 17 is shown in the positive y-direction and is a bad thing. Embodiments of the disclosed invention solve this problem.
A retention suture assembly is adapted to join a pair of edges from a wound The retention suture assembly comprises a first suture assembly, arranged proximate a first edge. The first suture assembly further comprises a first retaining bar, further comprising a first retaining bar outer perimeter, a first retaining bar upper plane and a first retaining bar lower plane. A first retaining bar upper opening further comprises a first retaining bar upper opening center and a first retaining bar lower opening further comprises a first retaining bar lower opening center. The first retaining bar lower opening center is relatively distant the first edge and the first retaining bar upper opening center is relatively proximate the first edge.
Similarly, a second suture assembly is arranged proximate a second edge and further comprises a second retaining bar, further comprising a second retaining bar outer perimeter, a second retaining bar upper plane and a second retaining bar lower plane. A second retaining bar upper opening further comprises a second retaining bar upper opening center and a second retaining bar lower opening further comprises a second retaining bar lower opening center. The second retaining bar lower opening center is relatively distant the second edge and the second retaining bar upper opening center is relatively proximate the second edge.
A suture joins the first suture assembly and the second suture assembly under tension. In some embodiments, the suture is tied into a knot. In other embodiments, the suture is tightened with a tensioning device.
In some embodiments an upper linear distance measured from the first retaining bar upper opening center to the second retaining bar upper opening center is less than a lower liner distance measured from the first retaining bar lower opening center to the second retaining bar lower opening center.
In some embodiments, the first suture assembly further comprises a first retaining bar tunnel, joining the first retaining bar upper opening and the first retaining bar lower opening; wherein the first retaining bar tunnel further comprises a first retaining bar side wall.
Similarly, the second suture assembly further comprises a second retaining bar tunnel, joining the second retaining bar upper opening and the second retaining bar lower opening; wherein the second retaining bar tunnel further comprises a second retaining bar side wall.
It follows that the suture is arranged through the first retaining bar tunnel such that the suture contacts the first retaining bar side wall distributing some of a force from the suture into the first retaining bar; the suture further arranged through the second retaining bar tunnel such that the suture contacts the second retaining bar side wall distributing some of the force from the suture into the second retaining bar pulling the first retaining bar to the second retaining bar.
A first retaining bar orthogonal axis, that is orthogonal to the first retaining bar upper plane and the first retaining bar lower plane, travels through the first retaining bar upper opening center. A first retaining bar tunnel axis travels through the first retaining bar upper opening center and the first retaining bar lower opening center. A first angle is measured clockwise from the tunnel axis to the first retaining bar orthogonal axis. The first angle is at least five degrees but no more than one hundred seventy-five degrees angled toward the first edge.
Similarly, a second retaining bar orthogonal axis, that is orthogonal to the second retaining bar upper plane and the second retaining bar lower plane, travels through the second retaining bar upper opening center. A second retaining bar tunnel axis travels through the second retaining bar upper opening center and the second retaining bar lower opening center. A second angle is measured counter clockwise from the tunnel axis to the second retaining bar orthogonal axis; wherein the second angle is at least five degrees but no more than one hundred seventy-five degrees angled toward the second edge.

A first retaining bar central opening, spanning two sides of the first retaining bar outer perimeter creating a first retaining bar lower tunnel having a first retaining bar lower tunnel central axis wherein the first retaining bar upper channel central axis is approximately perpendicular to the first retaining bar lower tunnel central axis.
A first foot extends from the first retaining bar lower plane between a first retaining bar first edge and the first retaining bar lower opening. A second foot extends from the first retaining bar lower plane between the first retaining bar lower opening and the first retaining bar central opening. A third foot extends from the first retaining bar lower plane between the first retaining bar central opening and the first retaining bar second opening. A fourth foot extends from the first retaining bar lower plane between the first retaining bar second opening and a first retaining bar second edge.
A central portion exists between the second foot and the third foot. In some embodiments the central portion is arched away from the second foot and the third foot in a concave manner. In some embodiments this arch makes the first retaining bar upper plane convex. In other embodiments, the arch does not affect the first retaining bar upper plane. In some embodiments a through connects the first retaining bar upper plane central opening and the second retaining bar upper plane central opening.
