Neurosurgical guide device
First Claim
1. A neurosurgical guide device comprising a tube for insertion into a brain of a patient to a vicinity of a desired target, wherein the tube has a head attached to one end thereof, the head having a passageway therethrough in communication with a bore of the tube and which terminates in an opening on the outer surface of the head, and having one or more formations on the head'"'"'s external surface for securing the device in a hole formed in a skull of a patient, whereby an instrument can be introduced through the opening and passed along the bore from a proximal end to a distal end thereof.

7. A method of positioning an instrument at a desired target in the brain of a patient, comprising:
-
(a) drilling a hole in the skull of the patient along a desired trajectory;
(b) inserting a neurosurgical guide device comprising a tube for insertion into a brain of a patient to a vicinity of a desired target, wherein the tube has a head attached to one end thereof, the head having a passageway therethrough in communication with the bore of the tube and which terminates in an opening on the outer surface of the head, and having one or more formations on its external surface for securing the device in a hole formed in a skull of a patient, into the hole along the desired trajectory and securing the head in the hole; and
(c) inserting the instrument through the opening and passing the instrument along the bore so that the instrument is positioned at the desired target. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

18. A neurosurgical guide device comprising a tube for insertion into a brain of a patient to a vicinity of a desired target, wherein the tube has a head attached to one end thereof, the head having a passageway therethrough in communication with the bore of the tube and which terminates in an opening on the outer surface of the head, and having one or more formations on its external surface for securing the device in a hole formed in a skull of a patient, whereby an instrument can be introduced through the opening and passed along the bore from a proximal end to a distal end thereof, and wherein the head has a slot which extends laterally of the longitudinal axis of the bore from the passageway to an outer surface of the head, for receiving, in use, a protruding end of an instrument located in the device.
