Device for immobilizing a primary instrument and method therefor

摘要

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.

主权项

1. A method for securing a deep brain stimulator electrode relative to a burr hole, comprising:
positioning a base relative to the burr hole; engaging a stabilizer with a tool to open a slot to an open configuration for receiving the electrode therein, the stabilizer having a pair of opposed movable sidewalls defining the slot, the slot extending through the stabilizer and radially inward from an outer perimeter of the stabilizer in the open configuration, the opposed sidewalls biased to a closed configuration and including opposed surfaces configured to directly engage the electrode; positioning the stabilizer relative to the base and the electrode such that the electrode is slidably received within the slot in the open configuration from the outer perimeter of the stabilizer while the opposed surfaces are facing each other; removing the tool from the stabilizer to close the slot to a closed configuration while maintaining the electrode within the slot as the opposed sidewalls move from the open configuration to the closed configuration while the opposed surfaces are facing each other to engage the electrode and secure the electrode relative to the base; and attaching a cover to the base.
