Multiple cannula image guided tool for image guided procedures
First Claim
1. An apparatus for the placement of surgical implements, comprising:
- a fixture that defines a plurality of attachment points that are spaced apart and fixed relative to each other;
a plurality of cannulas coupled to the fixture with each of the plurality of cannulas coupled to a respective one of the plurality of attachment points;
at least one trackable marker mounted on a frame that is coupled to the fixture to enable an instrument location system to detect a position of each of the plurality of cannulas throughout a surgical procedure without obstructing any of the cannulas during the procedure; and
a plurality of surgical implement receivers provided on the fixture for receiving surgical implements, at least one of the plurality of receivers being substantially coaxially aligned with a respective one of the plurality of cannulas to enable a surgical implement to pass through a respective one of the plurality of receivers and a respective one of the plurality of cannulas.

Abstract
Apparatus and methods are disclosed for use within an image-guided surgical navigation system for facilitating the combined positioning and orientation of multiple surgical implements. A tool guide having multiple cannulas is tracked by a surgical navigation system in real time. Position data of the tool guide is registered and combined with pre-acquired images by the navigation computer. Concurrent graphical representations of the plurality of cannulas are superimposed over the images and displayed. The display allows the surgeon to place the tool guide into the patient'"'"'s body and position and orient the plurality of cannulas which are then used to place each of the implements.

20. A kit for an apparatus for the placement of surgical implements, comprising:
-
a first fixture having a first configuration defined by a plurality of attachment points that are spaced apart and fixed relative to each other and a first frame coupling region; a second fixture different from the first fixture and having a second configuration defined by a plurality of attachment points that are spaced apart and fixed relative to each other and a second frame coupling region; a plurality of cannulas each operable to be coupled to at least one of the first fixture or the second fixture via one of the respective plurality of attachment points; and a trackable marker operable to be associated with all of the plurality of cannulas, the trackable marker mounted on a single frame, the single frame operable to be selectively coupled to the first frame coupling region of the first fixture or the second frame coupling region of the second fixture, wherein upon coupling the plurality of cannulas with the first fixture or the second fixture, the plurality of cannulas are positioned in at least one of the first configuration or the second configuration, and the trackable marker is detectable by an instrument location system to detect the position of the plurality of cannulas relative to an anatomy in real-time. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

30. An apparatus for the placement of surgical implements, comprising:
-
a fixture that includes a pistol grip configured grasping handle and a plurality of attachment points that are spaced apart and fixed relative to each other; a plurality of cannulas each coupled to a respective one of the plurality of attachment points of the fixture so that manipulation of the pistol grip configured grasping handle maneuvers the plurality of cannulas simultaneously and the plurality of cannulas are independently adjustable relative to the fixture; a plurality of trackable markers coupled to the fixture; a surgical navigation system that tracks the plurality of trackable markers to determine a position of each of the plurality of cannulas relative to an anatomy; and a display that displays an icon representative of the position of each of the plurality of cannulas superimposed onto an image of the anatomy. - View Dependent Claims (31, 32, 33, 34, 35)
