MEDICAL INSTRUMENT WITH SENSOR FOR USE IN A SYSTEM AND METHOD FOR ELECTROMAGNETIC NAVIGATION |
摘要 |
A medical instrument includes a sensor, a surface, at least one non-conductive material, and at least one pair of contacts. The sensor has at least one coil formed on a conductive material. The surface is suitable for receiving the sensor and can be placed in an EM field. The at least one non-conductive material covers the at least one coil of the sensor. The at least one pair of contacts are electrically connected to the at least one coil and connectable to a measurement device, which senses an induced electrical signal based on a magnetic flux change of the EM field. The location of the medical instrument in a coordinate system of the EM filed is identified based on the induced electrical signal in the sensor. |

1. A medical instrument comprising:
a sensor having at least one coil formed of a conductive material; a surface suitable for receiving the sensor and configured for placement in an electromagnetic field; at least one non-conductive material covering the at least one coil of the sensor; and at least one pair of contacts electrically connected to the at least one coil and connectable to a measurement device configured to sense an induced electrical signal based on a magnetic flux change of the electromagnetic field, wherein a location of the medical instrument in a coordinate system of the electromagnetic field is identified based on the induced electrical signal in the sensor. |
