Abstract

A method of surgical navigation into'"'"' the brain includes establishing a trajectory through the skull into the brain to a target, drilling a hole in the skull using a drill (14), and verifying the trajectory of the drilled hole during drilling using image guidance. A surgical navigation system includes a cannulated drill, a cannulated access member (30), and a coupling member (16) for coupling the access member to the drill and for maintaining alignment of the cannulations in the drill and the access member. The access member is movable relative to the coupling member such that the access member can be secured to tissue while the coupling member maintains the alignment of the cannulations. A surgical kit includes a cannulated drill, a cannulated access member, a coupling member for coupling the access member to the drill, and a probe for receipt within the cannulated drill.

Claims

1. A method comprising:

establishing a trajectory through the skull into the brain to a target,

drilling a hole in the skull using a drill,

verifying the trajectory of the drilled hole during drilling using image guidance provided by a probe received by the drill, and

placing an access member in the drilled hole using the drill,

verifying the trajectory of the access member during placement using a probe received by the drill.

2. The method of claim 1 wherein the drill defines a lumen.

3. The method of claim 2 wherein the probe is received in the lumen defined by the drill.

4. The method of claim 1, further comprising placing a medical device in a lumen defined by the access member.

5. The method of claim 4, further comprising securing the medical device in the access member.

6. The method of claim 4, wherein the medical device is selected from a group consisting of a ventriculostomy catheter, convention therapy catheter, epilepsy depth electrode, thermocoagulation probe, lesioning probe, stereotactic needle and ablative probe.

7. The method of claim 1, wherein the probe is tracked by navigation software.

8. The method of claim 7, wherein said navigation software tracks the probe relative to images of a patient'"'"'s body.
