Surgical probe with an integrated motion sensor
A surgical probe system comprising a surgical probe having an instrument tip, and at least one motion sensor located within the surgical probe that measures movement and orientation data. The system further includes a processor that is configured to determine movement and orientation of the instrument tip based on the movement and orientation data, and adjust at least one surgical parameter of the surgical probe based on the movement and orientation of the instrument tip to affect a predetermined surgical outcome.
1. A surgical probe system, comprising:
a laser surgical probe having an instrument tip that delivers laser power to an eye;
at least one motion sensor located within the laser surgical probe that measures movement and orientation data; and
a processor that:
determines movement and orientation of the instrument tip based on the movement and orientation data; and
adjusts the laser power of the surgical probe based on the movement and orientation of the instrument tip to affect a predetermined surgical outcome;
wherein when the laser probe delivers continuous laser power, the processor:
increases the laser power if faster movement is detected, or
decreases the laser power if slower movement is detected.
2. The surgical probe system as in claim 1 , wherein the movement and orientation data includes measured movement in a form of speed and acceleration along 3 axis (x, y, and z), and measured orientation in a form of rotations around those axes in a form of pitch, yaw, and roll.
3. The surgical probe system as in claim 1 , wherein the at least one motion sensor comprises at least one of an accelerometer and a gyroscope.
4. The surgical probe system as in claim 1 , wherein the at least one motion sensor is located within a handle of the surgical probe.
5. The surgical probe system as in claim 1 , wherein the at least one motion sensor is located near the instrument tip to directly measure the instrument tip movement and orientation data.
6. The surgical probe system as in claim 1 , wherein the at least one motion sensor is located within a handle of the surgical probe, and the surgical probe includes an additional motion sensor located near the instrument tip.
7. The surgical probe system as in claim 1 , wherein the processor is located remote from the surgical probe.
8. The surgical probe system as in claim 1 , wherein the processor is located within a handle of the surgical probe.
9. The surgical probe system as in claim 8 , wherein the processor is provided with a displacement parameter indicating 3-dimensional displacement of the at least one motion sensor away from the instrument tip, and wherein the processor uses the displacement parameter in combination with the movement and orientation data to derive the instrument tip movement and orientation data.
10. The surgical probe system as in claim 1 , wherein the laser probe includes surgical parameters for continuous laser power level and pulse laser activation/deactivation.
11. The surgical probe system as in claim 1 , wherein at least one surgical parameter is further adjusted by the processor based on retinal proximity detection performed by a retinal proximity detection sensor that detects proximity or distance between the instrument tip and a retina during surgery.
12. A surgical probe system, comprising:
a laser surgical probe having an instrument tip that delivers laser power to an eye;
at least one motion sensor located within the laser surgical probe that measures movement and orientation data; and
a processor that:
determines movement and orientation of the instrument tip based on the movement and orientation data; and
adjusts the laser power of the surgical probe based on the movement and orientation of the instrument tip to affect a predetermined surgical outcome;
wherein when the laser probe delivers pulsed laser power, the processor:
activates the laser power if no movement or slow movement is detected, or
deactivates the laser power if fast movement is detected.
13. The surgical probe system as in claim 12 , wherein the movement and orientation data includes measured movement in a form of speed and acceleration along 3 axis (x, y, and z), and measured orientation in a form of rotations around those axes in a form of pitch, yaw, and roll.
14. The surgical probe system as in claim 12 , wherein the at least one motion sensor comprises at least one of an accelerometer and a gyroscope.
15. The surgical probe system as in claim 12 , wherein the at least one motion sensor is located within a handle of the surgical probe.
16. The surgical probe system as in claim 12 , wherein the at least one motion sensor is located near the instrument tip to directly measure the instrument tip movement and orientation data.
17. The surgical probe system as in claim 12 , wherein the at least one motion sensor is located within a handle of the surgical probe, and the surgical probe includes an additional motion sensor located near the instrument tip.
18. The surgical probe system as in claim 12 , wherein the processor is located remote from the surgical probe.
19. The surgical probe system as in claim 12 , wherein the processor is located within a handle of the surgical probe.
20. The surgical probe system as in claim 19 , wherein the processor is provided with a displacement parameter indicating 3-dimensional displacement of the at least one motion sensor away from the instrument tip, and wherein the processor uses the displacement parameter in combination with the movement and orientation data to derive instrument tip movement and orientation data.
21. The surgical probe system as in claim 12 , wherein the laser probe includes surgical parameters for continuous laser power level and pulse laser activation/deactivation.
22. The surgical probe system as in claim 12 , wherein at least one surgical parameter is further adjusted by the processor based on retinal proximity detection performed by a retinal proximity detection sensor that detects proximity or distance between the instrument tip and a retina during surgery.
