System and method for identifying a landmark
First Claim
Patent Images
1. A method comprising:
- sterilizing a landmark identifier with autoclave sterilization, the landmark identifier comprising a plurality of magnetic field generating elements mounted to an internal mounting structure;
after sterilizing the landmark identifier, using the landmark identifier to identify one or more landmarks of an orthopaedic implant; and
after using the landmark identifier to identify the one or more landmarks of the orthopaedic implant, sterilizing the landmark identifier with autoclave sterilization.

Abstract
A field generator for use in a surgical targeting system is disclosed. The field generator includes a mounting structure including elements that are configured to receive components of an electromagnetic field generator. The elements are disposed on the mounting structure at locations and orientations relative to each other. The field generator includes at least one covering formed over the mounting structure, wherein, in use, the locations and orientations of the elements relative to each other remain substantially unaltered after exposure to one or more sterilization processes.
