Abstract

An optical shape sensing system includes an attachment mechanism (130) being configured to secure an optical shape sensing fiber to an instrument, the optical shape sensing fiber being connected to the instrument and configured to identify a position and orientation of the instrument. An optical shape sensing module (115) is configured to receive feedback from the optical shape sensing fiber and register the position of the instrument relative to an operating environment. A position response module (144) is configured to provide feedback to an operator based on position or orientation of the instrument to guide usage of the instrument.

Claims

1. An optical shape sensing system, comprising:

an attachment mechanism being configured to secure an optical shape sensing fiber to an instrument, the optical shape sensing fiber being connected to the instrument and configured to identify a position and orientation of the instrument;

an optical shape sensing module configured to receive feedback from the optical shape sensing fiber and register the position of the instrument relative to an operating environment; and

a position response module configured to provide feedback to an operator based on position or orientation of the instrument to guide usage of the instrument.

2. The system as recited in claim 1, wherein the attachment mechanism includes a detachable device configured to connect with a portion of the instrument.

3. The system as recited in claim 2, wherein the detachable device includes mateable portions to connect and disconnect from the instrument.

4. The system as recited in claim 3, wherein the detachable device is interchangeably mountable on a plurality of instruments.

5. The system as recited in claim 1, wherein the operating environment includes an operating room for a medical procedure and a position of the instrument is tracked relative to an anatomical map.

6. The system as recited in claim 1, wherein the position response module is configured to control instrument function based on a position of the instrument relative to an identified zone or position in the operating environment.

7. The system as recited in claim 1, wherein the position response module is configured to provide feedback to an operator when the instrument is positioned with a particular orientation.

8. The system as recited in claim 1, wherein the position response module initiates or halts use of the instrument when the instrument'"'"'s position changes.

9. An optical shape sensing system, comprising:

an optical shape sensing module configured to receive feedback from one or more optical shape sensing fibers;

one or more instruments having at least one optical shape sensing fiber connected thereto, the optical shape sensing fiber being employed to positionally track the instrument in an operating environment;

a position response module configured to provide feedback to an operator based on position or orientation of the instrument to guide usage of the instrument based on a surgical plan; and

an anatomical map included in a region of the operating environment wherein positions of the one or more instruments are tracked relative to the anatomical map.

10. The system as recited in claim 9, wherein the at least one optical shape sensing fiber is detachably mounted to the one or more instruments including mateable portions to connect and disconnect from an instrument.

11. The system as recited in claim 10, wherein the mateable portions include being interchangeably mountable on a plurality of instruments.

12. The system as recited in claim 9, wherein the position response module is configured to control instrument function based on a position of the instrument relative to an identified zone or position in the operating environment.

13. The system as recited in claim 9, wherein the position response module is configured to provide feedback to an operator when the instrument is positioned with a particular orientation.

14. The system as recited in claim 9, wherein the position response module initiates or halts use of the instrument when the instrument'"'"'s position changes.

15. A method for tracking instruments using optical shape sensing, comprising:

securing an optical shape sensing fiber to an instrument, the optical shape sensing fiber being connected to the instrument and configured to identify a position of the instrument;

registering position of the instrument relative to a stored image of an operating environment;

receiving feedback from the optical shape sensing fiber to determine a current position; and

guiding use of the instrument based upon the position and orientation of the instrument.
