Patent attributes
Systems and methods related to use of a measurement system in conjunction with a powered instrument for determination of the placement of a tool portion relative to the anatomy of a patient utilizing the powered instrument. The measurement system may include a displacement sensor that indicates the relative displacement of the tool portion relative to the anatomy. The system may also include a sensor for monitoring a tool drive signal representative of a tool drive parameter that is characteristic of the tool portion acting on the anatomy. The tool drive signal may be analyzed relative to a given amount of axial displacement as measured by the displacement sensor to avoid false indications of placement based on noise and or other artifacts in the tool drive signal that may result from characteristics of the anatomy and/or operational behaviors of the surgeon utilizing the instrument.
