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.

主权项

1. A system for introducing neurosurgical instruments into a skull of a patient, comprising:
a low profile skull anchor device comprising attachment means 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 attachment means provides a mounting height of the low profile skull anchor device of 30 millimeters or less from a surface of the skull of the patient; and a removable guide stem comprising
a locking means for detachably connecting the guide stem to the low profile skull anchor device,an access means for access to at least a portion of the entry, wherein the access means is positioned above the entry formed in the skull of the patient,a trajectory alignment means that adjusts at least one of a pivot alignment and a rotation alignment of the means for access, andat least one trajectory locking means for locking at least one of the pivot alignment and the rotation alignment at a current trajectory.
