Systems and methods for a stereotactic coordinate adjuster
Various embodiments of a stereotactic coordinate adjuster system and associated method for positional adjustment of components of a stereotactic system are disclosed herein. The system provides fine adjustment to the stereotactic system by providing form-fitting components that encapsulate components of the stereotactic system and allow for fine positional adjustment of an arc support member and a slide portion of the stereotactic system.

a coordinate adjuster configured for engagement with a stereotactic frame, the coordinate adjuster being distinct from the stereotactic frame and including:
a locator having a slide receptacle configured to receive a slide of the stereotactic frame, the locator including:
a guide slot defined along a vertical direction and a first pinion;
a track portion defined along a horizontal direction and being configured to receive a frame portion of the stereotactic frame; and
a second pinion adjacent the track portion;
a z-rack positionable within the guide slot and configured for engagement with an arc support member of the stereotactic frame, the z-rack having a first gear rack that engages the first pinion of the locator for translation of the arc support member along the vertical direction relative to the locator; and
a y-rack positionable configured for engagement with the frame portion of the stereotactic frame, the y-rack having a second gear rack that engages the second pinion of the locator for translation of the frame portion along the horizontal direction relative to the locator.
2 . The stereotactic coordinate adjuster system of claim 1 , wherein the coordinate adjuster is configured for engagement with a left portion or a right portion of the stereotactic frame.
3 . The stereotactic coordinate adjuster system of claim 1 , further comprising:
a first dial associated with the first pinion of the locator;
wherein rotation of the first dial causes translation of the z-rack and the arc support member along the vertical direction relative to the locator when the arc support member is engaged with the z-rack and when the z-rack is positioned within the guide slot of the locator.
4 . The stereotactic coordinate adjuster system of claim 3 , wherein translation of the z-rack and the arc support member along the vertical direction relative to the locator is independent from translation of the y-rack and the frame portion along the horizontal direction relative to the locator.
5 . The stereotactic coordinate adjuster system of claim 1 , the z-rack further including:
a ring support assembly at a head portion of the z-rack, the ring support assembly being configured for engagement with a ring of the arc support member of the stereotactic frame.
6 . The stereotactic coordinate adjuster system of claim 1 , wherein the z-rack is positioned along a first side of the locator and the arc support member is positioned along a second side of the locator when the arc support member is engaged with the z-rack and when the z-rack is positioned within the guide slot of the locator.
7 . The stereotactic coordinate adjuster system of claim 6 , wherein the y-rack and the frame portion are positioned between the z-rack and the arc support member when the frame portion is engaged with the y-rack and when the frame portion is received within the track portion of the locator.
8 . The stereotactic coordinate adjuster system of claim 1 , further comprising:
a second dial associated with the second pinion of the locator;
wherein rotation of the second dial causes translation of the y-rack and the frame portion along the horizontal direction relative to the locator when the frame portion is engaged with the y-rack and when the y-rack is received within the track portion of the locator.
9 . The stereotactic coordinate adjuster system of claim 8 , wherein translation of the y-rack and the frame portion along the horizontal direction relative to the locator is independent from translation of the z-rack and the arc support member along the vertical direction relative to the locator.
10 . The stereotactic coordinate adjuster system of claim 1 , the
the track portion being configured to receive a dovetail portion of the frame portion of the stereotactic frame.
11 . The stereotactic coordinate adjuster system of claim 1 , the second gear rack of the y-rack being oriented along a top surface of the frame portion of the stereotactic frame when the frame portion is engaged with the y-rack.
12 . A stereotactic coordinate adjuster system, comprising:
a coordinate adjuster configured for engagement with a stereotactic frame, the coordinate adjuster being distinct from the stereotactic frame and including:
a locator configured for engagement with a slide of the stereotactic frame, the locator defining a slide receptacle configured to receive the slide, and the locator including a guide slot defined along a vertical direction and having a first pinion; and
a z-rack positionable within the guide slot and configured for engagement with an arc support member of the stereotactic frame, the z-rack having a first gear rack that engages the first pinion of the locator for translation of the arc support member along the vertical direction relative to the locator.
13 . The stereotactic coordinate adjuster system of claim 12 , further comprising:
a first dial associated with the first pinion of the locator;
wherein rotation of the first dial causes translation of the z-rack and the arc support member along the vertical direction relative to the locator when the arc support member is engaged with the z-rack and when the z-rack is positioned within the guide slot of the locator.
14 . The stereotactic coordinate adjuster system of claim 12 , further comprising:
a ring support assembly at a head portion of the z-rack, the ring support assembly being configured for engagement with a ring of the arc support member of the stereotactic frame.
15 . The stereotactic coordinate adjuster system of claim 12 , further comprising:
a rail gripper along a head portion of the z-rack that applies a stabilizing force against the arc support member of the stereotactic frame.
16 . The stereotactic coordinate adjuster system of claim 12 , the guide slot of the locator including a tensioner element that contacts the z-rack and applies a stabilizing force to the z-rack when the z-rack is positioned within the guide slot.
17 . A stereotactic coordinate adjuster system, comprising:
a coordinate adjuster configured for engagement with a stereotactic frame, the coordinate adjuster being distinct from the stereotactic frame and including:
a locator having a slide receptacle configured to receive a slide of a stereotactic frame, the locator including;
a track portion defined along a horizontal direction and being configured to receive a dovetail portion of a frame portion of a stereotactic frame; and
a second pinion adjacent the track portion; and
a y-rack configured for engagement with the frame portion of the stereotactic frame, the y-rack having a second gear rack that engages the second pinion of the locator for translation of the frame portion along the horizontal direction relative to the locator.
18 . The stereotactic coordinate adjuster system of claim 17 , further comprising:
a second dial associated with the second pinion of the locator;
wherein rotation of the second dial causes translation of the y-rack and the frame portion along the horizontal direction relative to the locator when the frame portion is engaged with the y-rack and when the frame portion is received within the track portion of the locator.
19 . The stereotactic coordinate adjuster system of claim 17 , the y-rack further including:
an outer surface clip configured to engage a shoulder of the frame portion of the stereotactic frame.
20 . The stereotactic coordinate adjuster system of claim 17 , the second gear rack of the y-rack being oriented along a top surface of the frame portion of the stereotactic frame when the frame portion is engaged with the y-rack.
