Neurosurgical guiding tool

摘要

The present invention regards a guiding tool for neurosurgery. The guiding tool comprises subunits and a holder. The subunits are arranged in the holder so that holes for guiding a probe are created in the interface between said subunits, which allows easy release of the probe. The invention further regards a system for guiding neurosurgery probes.

主权项

1. A guiding tool for guiding a deep brain stimulation probe into tissue, the guiding tool comprising: a plurality of subunits, each of the plurality of subunits having an indentation along an edge; and a holder configured to hold together the plurality of subunits, wherein the plurality of subunits are configured to be mounted in the holder to form a guiding tool including a plurality of holes, the plurality of holes including a central hole and two or more holes spaced around the central hole such that the central hole is generally in a center of the plurality of holes, each of the plurality of holes being formed around a complete perimeter by only two of the indentations, wherein the tool is configured to receive a distal end of the probe through at least one hole of the plurality of holes to guide the distal end of the probe into the tissue to implant the distal end of the probe while the probe is disposed within the at least one hole, and wherein the plurality of subunits are configured to be dismantled from the deep brain stimulation probe while the distal end of the deep brain stimulation probe is implanted into the tissue and while the probe is disposed within the at least one hole without drawing the deep brain stimulation probe through the at least one hole of the plurality of holes to remove the probe from within the at least one hole.
