1. An apparatus, comprising:
a shaft assembly extending along a longitudinal axis;
a rigid end effector fixed relative to the shaft assembly, the rigid end effector having a central axis that is obliquely oriented relative to the longitudinal axis;
a first opening that defines the central axis and is positioned along the longitudinal axis;
a second opening extending through the rigid end effector and being coplanar with the first opening; and
a sensor disposed at a position along the longitudinal axis of the shaft assembly, the sensor being configured to generate a signal in response to a magnetic field, the signal being configured to indicate a position of the rigid end effector within three-dimensional space.
