Benefits of technology

The present invention provides an orthopedic stabilization device and button-suture assembly that can automatically lock when the tension is released or ceases to exist. This mechanism utilizes the tension generated during tensioning to securely lock the construct. A design of the assembly is provided that maximizes the tensile strength of the construct by increasing the surface area of contact between the tensioning member and the locking elements. This reduces stress that the tensioning member is exposed to in a locked state. Overall, this invention improves the efficiency and accuracy of surgical procedures.

Problems solved by technology

Assemblies that secure bone and tissue fragments lose tension before the assemblies can lock resulting in inefficient placement of the assembly during surgical procedures.

Abstract

Embodiments of knotless button-suture assemblies for orthopedic stabilization are disclosed. The button-suture assembly includes a button having a first opening, a second opening and a center opening. The assembly further includes a tensioning member having two tensioning member ends exiting from the first opening and the second opening of the button and disposed in the proximal direction. The assembly further includes a locking pin mated with the button through the center opening of the button in such a manner that allows a proximal movement of the tensioning member when a pulling force is applied to the tensioning member ends towards a proximal direction and prevents a distal movement of the tensioning member when the pulling force applied to the loose ends of the tensioning member ceases to exist.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 62 / 817,313, filed on Mar. 12, 2019, which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention is generally directed toward a device and a method for use in a surgical repair of bone or tissue. More particularly, the present invention relates to the stabilization or repair of two or more bones or tissue fragments in orthopedic procedures.BACKGROUND OF THE INVENTION[0003]Bone suspension devices, such as button-suture assemblies, that stabilize bone and tissue are known in the art. The current devices secure the bone by locking the suture or other tensioning member in place via a knot. In these procedures, after a hole is drilled through the bone, tensioning members are passed through it and fixated on the distal side of the hole. The bones are then pulled closer together and a knot is tied on the proximal side of the...
