TISSUE DISPLACEMENT TOOLS AND METHODS

摘要

Apparatus and methods for bone cavity preparation. Formed broaching members may be supported inside a bone by a rotator. The broaching members may be bowed out inside the bone to create a cavity having a shape determined by the broaching members and bone anatomy.

主权项

1. A tissue cavity preparation tool comprising:
a first elongated body having a first sharp edge and a first face, wherein the first elongated body curves in a plane parallel to the first face when the first elongated body is in a planar configuration; a second elongated body having a second sharp edge and a second face, wherein the second elongated body curves in a plane parallel to the second face when the second elongated body is in a planar configuration; and an elongated rotator defining a longitudinal axis and being configured to:
retain a first end of the first body and a second end of the first body such that the first end is spaced longitudinally apart from the second end and the first face forms a first cone-like surface; andretain a first end of the second body and a second end of the second body such that the first end of the second body is spaced longitudinally apart from the second of the second body and the second face forms a second cone-like surface;wherein the first elongated body is disposed opposite the second elongated body.
