First Claim
1. An alignment system for an imaging device comprising:
- an alignment device comprising;
a base, the base having an affixation deice to mount on a patient surface;
an insertion guide, having an opening therein and an insertion axis through the opening;
an adjustable joint attached to a distal end of the insertion guide, and coupled to the base;
an MR compatible local device including;
a slide body movably coupled to the base;
a block slidably attached to the slide body;
a collar engaged to the insertion guide and movably retained by the block, the collar and block forming a ball and socket joint between the block and the insertion guide; and
a threaded adjuster coupled to the block, the threaded adjuster configured to cause linear motion of the collar with respect to the slide;
an actuator detachably coupled to the local adjustment device, wherein the actuator is spaced apart from the local adjustment device to enable location of the actuator outside an imaging region of the imaging device while the local adjustment device is within the imaging region of the imaging device; and
a control module in remote communication with the actuator and in communication with the imaging device, the control module aligning the insertion axis with the target location.

Abstract
A surgical alignment device is shown that is controlled remotely through the use of an actuator, where the actuator in turn controls at least one local adjustment device. The alignment device is suited for neurosurgery, although it is not exclusively limited to neurosurgery. The alignment device includes an insertion guide that is coupled to the local adjustment device, the insertion guide being used to guide a device such as a catheter into a patient. The alignment device may also be coupled to a control module such as a microcomputer that controls the orientation of the insertion guide in response to inputs from the surgeon as to a location of interest within the patient.

12. A method of aligning a medical device comprising:
-
coupling a base to a patient reference frame; attaching an insertion guide to the base using an adjustable joint, the insertion guide having an insertion axis, and the adjustable joint having a range of motion; attaching a local adjustment device to the adjustable joint, the local adjustment device including a slide body movably coupled to the base, a block slidably attached to the slide body, and a collar angaged to the insertion guide and movably retained by the block, the collar and block forming a ball and socket joint between the block and the insertion guide; coupling an actuator to the local adjustment device;
wherein coupling the actuator to the local adjustment device includes remotely coupling the actuator to the local adjustment deviceremotely actuating the actuator to adjust alignment of the insertion axis within the range of motion, the actuator configured to cause at least one of motion of the slide body with respect to the base and linear motion of the block with respect to the body, the motion of the slide body with respect to the base being one of linear motion and rotatable motion; and detaching the actuator from the local adjustment device upon completion of a procedure. - View Dependent Claims (13, 14, 15, 16, 17)
