Abstract
A surgical instrument can include a body, a tracking device, and a handle. The tracking device can be positioned adjacent the distal end for tracking a distal tip of the instrument. The tracking device can include a pair of lead traces defined on a tubular flex circuit around the body to the handle, where the traces define at least on coil configured to communicate with a navigation system.
Claims31
A tracking device associated with a medical instrument having a shaft and a medical device navigation system, the tracking device comprising:
- an elongated tubular substrate having an exterior surface and a longitudinal axis;
- and
- a first electrical trace defining a first coil, the first coil configured to interact with the navigation system.
A surgical instrument, comprising:
- an elongated body having a proximal end and a distal end;
- a tracking device positioned adjacent the distal end and adapted to cooperate with a navigation system to track the distal end of the body, the tracking device having a tubular flexible circuit defining at least one coil, the tubular flexible circuit disposed between the proximal and distal ends;
- and
- a handle coupled to the proximal end of the elongated body, the tubular flexible circuit extending at least a pair of lead traces disposed along the body from the coil to the handle.
A surgical instrument, comprising:
- an elongated tubular body;
- a flexible tubular circuit having a proximal end and a distal end, the proximal end of the flexible circuit being disposed over the body, and defining first and second coil traces adjacent to the distal end, the first and second coil traces adapted to cooperate with a navigation system to track the distal end, the flexible tubular circuit including at least a pair of lead traces disposed along the body;
- and
- a handle coupled to the proximal end of the body.
