Motorized Stereotaxic Instrument
Since its introduction in 1908 the stereotaxic instrument has remained largely unchanged until now
And it’s about time......
RoboMate STX Motorized Stereotaxic
• 8 micron linear and 5 arcmin minimum angular increments
• Virtual Point (TM) Laser Positioning
• Precisely reach any target within the brain (regardless of approach angle)
• Clear and Unobstructed access to the operative field
• Precise software control of position, direction and speed
• Computer and/or Joystick Control both direction and velocity of movement
• Movement in 6 axes
• Undetectable backlash and drift
For nearly 100 years the basic design principle used in standard stereotaxic instruments has
remained relatively unchanged based on traditional XY and XYZ linear displacement
configurations. So not only does RoboMate STX represent the first motorized stereotaxic it is
also the lone stereotaxic instrument that can precisely position the probe/electrode/needle
at infinitely variable angles with respect to the target .
The core of the system’s design is an advanced piezoelectric rotary motor driven by a digital
signal processor (DSP) based controller. When the motor is de-energized, it operates as a
steadfast position holder (brake) with almost undetectable backlash and drift.
Using laser guided Virtual Point (TM) technology the tip of the probe/electrode/needle remains fixed so that no matter at what angle the probe/electrode/needle is placed, its tip will always precisely reach your target within the brain.
The Virtual Point is formed where the axis of rotation of the first and second rotary motors and
the longitudinal axis of the probe/electrode/needle intersect. When the tip of the probe/
electrode/needle is positioned at the Virtual Point, changes in the angle of the probe/tool will
not affect the position of the tip of the probe, which will remain at the Virtual Point.
The angular adjustments afford two additional advantages:
(1) In different operations, diverse superstructures may be traversed on the
way to the same target, thereby providing a control against incidental
destruction of any particular structure in the brain above the target.
(2) They make it very convenient to reach targets on the mid-line without
having the approach obstructed by the sagittal (longitudinal) sinus. |
