Targeting an orthopaedic implant landmark
First Claim
1. A system for targeting a landmark on an orthopaedic implant comprising:
- an autoclavable device comprising;
an autoclavable housing,a mounting structure disposed within the housing; and
a field generator mounted to the mounting structure for generating an electromagnetic field, wherein the autoclavable device is operable after autoclave sterilization of the autoclavable device;
a first electromagnetic sensor for disposition at a set distance from the landmark that generates sensor data in response to the generated electromagnetic field; and
an element removably coupleable to the housing, the element defining a longitudinal axis that represents one axis of the generated electromagnetic field, wherein the system is configured to use the one axis of the generated electromagnetic field to determine the position of the element relative to the landmark.

Abstract
A system for targeting landmarks on devices such as surgical implants is disclosed. The system can include a field generator for generating one or more magnetic fields, an orthopaedic implant located within the magnetic fields, the implant having at least one landmark, a removable probe with a first magnetic sensor, a landmark identifier and a processor. The landmark identifier can contain a second sensor, or, alternatively, the field generator. The processor can utilize sensor data and, if desirable, field generator and other information, to generate and display the position and orientation of the sensor(s) in preferably six degrees of freedom, and thereby, to generate and display the position and orientation of the landmark(s). The system allows for blind targeting of one or more landmarks. The landmark identifier, field generator and/or drill motor may be disposed in an autoclavable housing.
