First Claim
1. A method of performing a procedure with a first instrument so that a configuration of the first instrument is included in a view produced from a surgical navigation process used to perform the procedure, the method comprising:
- detecting a location in a first configuration relative to each other of at least a first tracking emitter with a medical instrument holder and at least three second tracking emitters defining a plane with a tracking device holder;
changing a pattern of said first and second tracking emitters;
detecting said changed pattern of said first and second tracking emitters; and
relating said changed pattern of said first and second tracking emitters with a change between a first instrument configuration and a second instrument configuration, wherein changing a pattern of said first and second tracking emitters includes switching a first signal module between a first condition and a second condition and wherein said change between said first condition and said second condition comprises;
emitting light and not emitting light from at least one of said first and second tracking emitters while maintaining the first configuration relative to each other.

Abstract
A navigation system generally determines a location of a portion of a first medical instrument relative to a patient. The navigation system generally includes a multi-configuration tracking array that extends from the first medical instrument. A plurality of tracking devices can be positioned on the multi-configuration tracking array. At least one of the tracking devices changes to define at least a first condition and a second condition. A tracking system detects the tracking devices and relates a change between the first condition and the second condition with a change between at least a first instrument configuration and a second instrument configuration.

15. A method of performing a procedure with a first instrument and a second instrument so that a configuration of the first instrument and the second instrument are included with a view produced from a surgical navigation process, the method comprising:
-
detecting a first tracking device and a second tracking device on a tracking apparatus having a tracking device holder member with said first tracking device and an instrument holder member with said second tracking device, said instrument holder member removably coupled to the first instrument, such that said instrument holder member is operable to be connected separately to both the first instrument and the second instrument; operating at least one tracking emitter of at least one of said first tracking device or said second tracking device to emit light to generate a first pattern or not emit light to generate a second pattern different than the first pattern; and detecting the first pattern or the second pattern of light emitted from said first tracking device and second tracking device. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method of selecting a view of a first instrument so that a configuration of the first instrument is included in a view produced from a surgical navigation system, the method comprising:
-
selecting at least one of a first medical instrument tip with a connected first tracking device or a second medical instrument tip with a connected second tracking device; connecting said selected first medical instrument tip or said second medical instrument tip to a device holder having a connected third tracking device; operating the surgical navigation system to determine a first pattern or a second pattern including a relative location of said connected third tracking device and at least one of said first tracking device or said second tracking device; and operating the surgical navigation system to determine the identification of the selected first instrument tip or the second instrument tip for producing the view. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of producing a view from a surgical navigation system, the method comprising:
-
selecting at least one of a first medical instrument tip with a connected first tracking device or a second medical instrument tip with a connected second tracking device; selecting a device holder having a connected at least one third tracking device; connecting said selected first medical instrument tip or said second medical instrument tip to said selected device holder to form a first pattern of said connected first tracking device and said at least one third tracking device or a second pattern of said second tracking device and said at least one third tracking device; operating the surgical navigation system to detect said first pattern or said second pattern, wherein said first pattern is different from said second pattern; operating the surgical navigation system to determine an identification of a feature of said first medical instrument tip or said second medical instrument tip based on said operation of the surgical navigation system to detect said first pattern or said second pattern; and operating the surgical navigation system to display the determined feature. - View Dependent Claims (32, 33, 34, 35, 36)

37. A navigation system that determines a location of a portion of a first medical instrument relative to a patient, the navigation system comprising:
-
a tracking apparatus having at least one first tracking device connected thereto; a device holder having a tip connection portion, wherein the tracking apparatus is connected to the device holder at a fixed position relative to the tip connection portion; a first instrument tip having a first connection portion configured to connect to the tip connection portion of the device holder and a second tracking device connected to the first instrument tip a first distance from the first connection portion; a second instrument tip having a second connection portion configured to connect to the tip connection portion of the device holder and a third tracking device connected to the second instrument tip a second distance from the second connection portion different than the first distance; a tracking system configured to detect all of the at least one first tracking device, the second tracking device, and the third tracking device; a surgical navigation system configured to identify a first feature of the first instrument tip when connected to the device holder based on a first pattern of the at least one first tracking device and the second tracking device and identify a second feature of the second instrument tip when connected to the device holder based on a second pattern of the at least one first tracking device and the third tracking device. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45)

46. A navigation system that determines a location of a portion of at least a first medical instrument relative to a patient, the navigation system comprising:
-
a tracking apparatus having a tracking device holder portion moveable relative to a medical device holder portion, wherein the medical device holder portion is configured to be selectively coupled to the first medical instrument, the medical device holder portion having a seat wall configured to engage the first medical instrument when a catch member moves via a lever assembly to capture the first medical instrument between the catch and the seal wall; a lock assembly operably connected to the tracking apparatus having a nut captured in a bore of a body of the tracking apparatus and a fastener extending through a spring from a lock handle, wherein the lock handle is configured to move from a locked position to compress the spring and fix the tracking device holder portion relative to the medical device holder portion and an unlocked position to decompress the spring to allow movement of the tracking device holder portion and the medical device holder portion; a plurality of emitters connected to the tracking device holder, wherein the plurality of emitters are positioned relative to each other and configured to emit a first pattern at a first condition and to emit a second pattern at a second condition, said plurality of emitters being changeable between said first condition and said second condition and thereby emit one of the first and second pattern, wherein the first pattern is different from the second pattern; and a tracking system that detects said plurality of emitters and relates a change between said first condition and said second condition with a change between at least a first instrument configuration and a second instrument configuration; wherein the lock assembly is configured to unlock the tracking device holder portion relative to the medical device holder portion to allow the change from the first pattern to the second pattern and to lock the tracking device holder portion relative to the medical device holder portion to fix the first pattern or the second pattern. - View Dependent Claims (47, 48, 49, 50, 51, 52)
