Cutting/bending tool for polymer implant

摘要

A first tool is configured to cut a polymer implant, and includes a handle, a cutting portion, and a bending portion. A second tool is configured to cut a polymer implant, and includes a handle, a first cutting portion, and a second cutting portion. The cutting portions contain a cutter that is preferably a blade. In the second tool, the blades are preferably angled with respect to each other between about 45°. The tools can be used to reshape an implant that is to be used to replace a portion of a skull.

主权项

1. A polymeric implant cutting tool that is configured to cut a polymeric implant, the tool comprising:
a tool body having a length along a first direction and including a handle portion comprising an upper handle portion and a lower handle portion spaced from the upper handle portion along a second direction, substantially perpendicular to the first direction, the upper handle portion having an outer surface and an opposing inner surface and the lower handle portion having an outer surface and an opposing inner surface; a first cutting portion located at a distal portion of the tool body, the first cutting portion including a first cutting prong and a second cutting prong, the first cutting prong having an end and a first prong inner surface, and the second cutting prong having an end and a second prong inner surface that is spaced from the first prong inner surface along the second direction, the first cutting portion further including a first cutter having a first cutting edge to cut the implant, the first cutting edge being located longitudinally inward from the end of the first prong and the first cutter defining a substantially planar configuration that extends along a plane, wherein the plane is at an angle that is substantially perpendicular to the first direction and substantially parallel to the second direction; and a second cutting portion located at a proximal portion of the tool body, the second cutting portion including a third cutting prong and a fourth cutting prong, the third cutting prong having an end and a third prong inner surface, and the fourth cutting prong having an end and a fourth prong inner surface that is spaced from the third prong inner surface along the second direction, the second cutting portion further including a second cutter having a second cutting edge to cut the implant, the second cutting edge being located longitudinally inward from the end of the third prong and being positioned at an angle of between 30° and 60° from the first cutting edge, wherein the handle portion is between the first cutting portion and the second cutting portion.
