Abstract
A surgical instrument having a position sensor that may be detachable, disposable, partially isolated from movement of the main body of the surgical instrument, and/or configured to display feedback lighting. The orientation of the surgical instrument may be mimicked either virtually or by a mechanical device with a second surgical instrument. The instruments of the present disclosure may be used in any procedure or treatment that would benefit from position feedback for the instruments.
Claims18
A surgical instrument comprising:
- an instrument body;
- and
- an absolute orientation sensor including an absolute orientation sensing component, wherein the absolute orientation sensor is configured to be attached to the instrument body such that when the absolute orientation sensor is attached to the instrument body the absolute orientation sensing component would be partially fixed relative to the instrument body, and wherein when the absolute orientation sensing component is at least partially fixed relative to the instrument body the absolute orientation sensing component would be operable to detect a plurality of orientation data associated with at least one orientation condition of the surgical instrument relative to the Earth's magnetic field without requiring calibration by a separate arbitrary reference plane;
- wherein the absolute orientation sensor is configured to partially isolate movement of the instrument body from absolute orientation sensing component when the absolute orientation sensor is attached to the instrument body, whereby when the absolute orientation sensing component is partially fixed relative to the instrument body the instrument body would be partially movable relative to the absolute orientation sensing component;
- and
- wherein the absolute orientation sensor includes a ratchet that is configured to allow the instrument body to move relative to the absolute orientation sensing component in a first direction and configured to not allow the instrument body to move relative to the absolute orientation sensing component in a second direction opposite the first direction, and wherein the absolute orientation sensor is concentric with the ratchet.

- wherein the instrument body includes a handle for a user to hold, wherein the handle extends proximally of the ratchet and the absolute orientation sensor,
- wherein the instrument body includes a shaft extending distally of the handle, the ratchet, and the absolute orientation sensor, wherein the handle and the shaft are configured to rotate in the first direction relative to the absolute orientation sensing component,
- wherein the absolute orientation sensor includes a display that is operatively coupled to a device processor, of the surgical instrument, and fixed relative to the absolute orientation sensing component, and wherein the absolute orientation sensor includes a sleeve that is fixed relative to the display and the absolute orientation sensing component, whereby the handle and the shaft are configured to rotate in the first direction relative to the sleeve and the display, and the handle is not configured to rotate in the second direction relative to the sleeve and the display.
