Abstract
A probe is provided. The probe may include a shaft portion rotatably attachable to a position sensing device, a nonlinear portion at least partially removed from a center axis of the shaft portion, and a tip disposed at a distal end of the nonlinear portion and positioned on the center axis. The nonlinear portion may be selectably rotatable about the center axis to one of a plurality of rotational orientations. The tip may have a substantially constant position relative to the position sensing device.
Claims20
A probe, comprising:
- a shaft portion rotatably attachable to a position sensing device;
- a nonlinear portion of fixed geometry that is at least partially removed radially outward from both an outer diameter and a center axis of the shaft portion, and selectably rotatable about the center axis to one of a plurality of rotational orientations;
- and
- a tip disposed at a distal end of the nonlinear portion and positioned on the center axis, the tip having a substantially constant position relative to the position sensing device, the tip including a sensing mechanism configured to generate electronic signals corresponding to changes in proximity of an anatomic surface relative to the tip.

A surgical device, comprising:
- a handle rotatably attachable to a position sensing device;
- and
- a probe coupled to the handle, the probe comprising a nonlinear connector and a tip, the nonlinear connector being of fixed geometry that is at least partially removed radially outward from both an outer diameter and a center axis of the handle, and rotatable about the center axis to one of a plurality of rotational orientations, the tip having a substantially constant position relative to the position sensing device, the tip including a sensing mechanism configured to generate electronic signals corresponding to changes in proximity of an anatomic surface relative to the tip.
A surgical system, comprising:
- a position sensing device;
- a probe rotatably coupled to the position sensing device, the probe comprising a nonlinear connector and a tip having a sensing mechanism configured to collect positioning data from an anatomic surface and generate electronic signals corresponding to the positioning data, the nonlinear connector being of fixed geometry that is at least partially removed radially outward from both an outer diameter and a center axis of the probe, and rotatable about the center axis to one of a plurality of rotational orientations relative to the position sensing device, the tip having a substantially constant position relative to the position sensing device;
- and
- a computer system in communication with the probe, the computer system configured to receive the positioning data from the tip, and digitize points of the anatomic surface based on the positioning data.
