First Claim
Patent Images
1. A device for immobilizing a primary instrument, comprising:
- a base configured to be secured about an entry portal in a surface, the base including a substantially ring shaped portion having a plurality of leg portions extending radially outward therefrom, the leg portions each including apertures configured to facilitate securing the base to the surface, the base defining an access lumen and having at least one channel in a top surface thereof;
a first slide slidable within the channel of the base;
a second slide slidable within the channel of the base, wherein the first and second slides are configured to be slid toward each other along a longitudinal axis of the channel to substantially cover the access lumen and grip the instrument in a closed position and release the instrument in an open position, and wherein each slide includes a radially inward instrument gripping end and a laterally opposite radially outward end; and
a laterally extending slot formed in a top surface of at least one of the first and second slides, the slot extending along an entire length of at least one of the slides from the instrument gripping end to the radially outward end so as to accommodate a portion of the instrument therein.

Abstract
Devices and methods provide accurate targeting, placement, and/or stabilization of an electrode or other instrument(s) into the brain or other body organ, such as to treat severe tremor or other neurological disorders. Targeting is performed using any form of image-guidance, including real-time MRI, CT, or frameless surgical navigation systems.

9. A method, comprising:
-
securing a substantially ring shaped immobilizing device about an entry portal in a surface; passing an instrument at least partially through an access lumen in the immobilizing device; sliding a first slide and a second slide toward each other within a channel in a top surface of the immobilizing device to substantially cover the access lumen and grip the instrument, wherein the first and second slides are slid toward each other along a longitudinal axis of the channel; and anchoring the instrument in a slot formed in a top surface of at least one of the first and second slides along the longitudinal axis of the channel, the slot extending along an entire length of at least one of the slides from a radially inward instrument gripping end to a longitudinally opposite radially outward end. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A device for immobilizing a primary instrument, comprising:
-
a base configured to be secured about an entry portal in a surface of an anatomy, the base including a substantially ring shaped portion having a plurality of legs extending radially outward from an outer periphery of the base, the legs each including at least one aperture configured to receive a bone screw for securing the base to the surface of the anatomy, the base defining an access lumen and having at least one channel in a top surface thereof and diametrically opposed receiving sides configured to attach equipment thereto, each receiving side defining a flattened planar section with an undercut on the outer periphery of the substantially ring shaped base; a first slide slidable within the channel of the base; a second slide slidable within the channel of the base, wherein the first and second slides are configured to be slid toward each other along a longitudinal axis of the channel to substantially cover the access lumen and grip the instrument in a closed position and release the instrument in an open position, and wherein each slide includes a radially inward instrument gripping end and a laterally opposite radially outward end and a top surface coplanar with the top surface of the base; and a laterally extending slot formed in the top surface of each of the first and second slides along the longitudinal axis of the channel, the slot extending along an entire length of each slide from the instrument gripping end to the radially outward end so as to accommodate a portion of the instrument therein.
