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, 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, and a coupling member 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 system comprising:

a cannulated drill;

a cannulated access member; and

a coupling member 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 being 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.

2. The system of claim 1 further comprising a medical device for receipt within the cannulated drill.

3. The system of claim 2, wherein said 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.

4. The system of claim 1, further comprising a probe.

5. The system of claim 4, wherein said probe is adapted to be tracked by navigation software.

6. The system of claim 1 further comprising a drill bit.

7. A kit comprising:

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.

8. The kit of claim 7 further comprising a drill bit.

9. The kit of claim 7 further comprising a medical device.

10. The kit of claim 7 further comprising a robot arm.

11. The kit of claim 9, wherein said 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.
