Abstract
An apparatus includes a shaft assembly, an end effector, and a sensor. The shaft assembly defines a longitudinal axis. The end effector is positioned at a distal end of the shaft assembly. A portion of the end effector is offset from the longitudinal axis. The sensor is configured to generate a signal in response to a magnetic field. The signal is configured to indicate a position of the end effector within three-dimensional space. The sensor is coaxially positioned about the longitudinal axis.
Claims20
An apparatus, comprising:
- (a) a shaft assembly, wherein the shaft assembly defines a longitudinal axis;
- (b) an end effector positioned at a distal end of the shaft assembly, wherein a portion of the end effector is offset from the longitudinal axis;
- and
- (c) a sensor, wherein the sensor is configured to generate a signal in response to a magnetic field, wherein the signal is configured to indicate a position of the end effector within three-dimensional space, wherein the sensor is coaxially positioned about the longitudinal axis.

An apparatus, comprising:
- (a) a grip;
- (b) a shaft assembly extending distally from the grip, wherein the shaft assembly defines a longitudinal axis;
- (c) an end effector positioned at a distal end of the shaft assembly, wherein the end effector comprises a loop blade, wherein the loop blade is offset from the longitudinal axis;
- and
- (d) a sensor, wherein the sensor is configured to generate a signal in response to a magnetic field, wherein the signal is configured to indicate a position of the loop blade within three-dimensional space, wherein the sensor is coaxially positioned about the longitudinal axis.
2 more elements
A method, comprising:
- (a) inserting a distal end of an instrument into a patient;
- (b) observing a display showing the position of the distal end of the instrument in the patient in real-time, wherein the display is driven by a processor processing signals from a sensor in the distal end of the instrument, wherein the sensor generates the signals in response to a magnetic field;
- and
- (c) engaging a transversely extending portion of the distal end of the instrument with tissue in the patient based on the observed position, wherein the transversely extending portion of the distal end is offset from a longitudinal axis of a shaft assembly of the instrument, wherein the sensor is coaxially positioned about the longitudinal axis.
