Model 1950 Off-Plane Insertion Tool

Model 1950 Off-Plane Insertion Tool is designed for angular electrode presentations, offering two additional axes of manipulation when used in combination with a Kopf 1900 series micro manipulator.

Coronal Angle - 0-45°
Dorsal Angle - +/-90°
Z2 Axial movement - 25 mm
Linear movement minimum division - .010 mm
Coronal Angle minimum division - 1.0°

The coronal arch (A-axis) has repeatable pin index positions every 5°. A large knurled locking screw provides locking at subsequent positions anywhere along the arch. The coronal arch may be rotated about the vertical axis +/-90° with repeatable pin index positions every 15° to create the compound angles of both coronal and dorsal presentations.

The electrode or cannula is advanced into the brain via the axial slide “Z2”. The Z2 slide is a precision dovetail slide with calibrated dial. Dial is calibrated in .010 mm increments with .50 mm per revolution.

Model 1950 is produced in both left and right hand models so bilateral off-plane presentations may be made across the midline of the brain utilizing two electrode manipulators.

Unit does not include stereotaxic holders. See catalog pgs. 66 - 68 for available products.

Stereotaxic holder shaft length requires modification for use with Model 1950 Off-Plane Insertion Tool.
