IMAGE-GUIDED THERAPY OF A TISSUE

摘要

Image-guided therapy of a tissue can utilize magnetic resonance imaging (MRI) or another medical imaging device to guide an instrument within the tissue. A workstation can actuate movement of the instrument, and can actuate energy emission and/or cooling of the instrument to effect treatment to the tissue. The workstation and/or an user of the workstation can be located outside a vicinity of an MRI device or other medical imaging device, and drive means for positioning the instrument can be located within the vicinity of the MRI device or the other medical imaging device. The instrument can be an MRI compatible laser or high-intensity focused ultrasound probe that provides thermal therapy to, e.g., a tissue in a brain of a patient.

1. A neurosurgical instrument introduction apparatus comprising:
a low profile skull anchor device configured to attach to an area of a skull of a patient, wherein
the low profile skull anchor device comprises a central opening at least sixty millimeters in diameter for providing access to an entry formed in the skull of the patient, andthe low profile skull anchor device is configured to connect to the skull of the patient using a plurality of fasteners such that a gap is maintained between a surface of the skull of the patient and the low profile skull anchor device, wherein the gap is at most 30 millimeters from the surface of the skull of the patient; and a removable guide stem configured to detachably connect to the low profile skull anchor device, wherein
the removable guide stem comprises an opening that, when connected to the low profile skull anchor device, is positioned above the entry formed in the skull of the patient, and the removable guide stem is configured to adjust a trajectory corresponding to the opening of the removable guide stem in at least one of a pivot alignment and a rotation alignment.
