|Stereotactically Guided Open Craniotomy|
The Stereoadapter is an excellent means for the surgeon to locate tumors for open surgery. Due to its inherent precision the Stereoadapter may be successfully utilized even for small subcortical tumors.
Before surgery the Stereadapter is re-mounted on the patient exactly as in earlier imagings. The CT/MRI targets and the
tumor margins are drawn on the scalp in relation to the Stereoadapter which is thereafter removed. The craniotomy can be
accurately planned and performed through a minimal bone opening and cortical incision.
|Percutaneous Tumor Biopsy Without Invasive Frame |
The Steroadapter with optional
Percutaneous Tumor Biopsy Kit permits safer and more simplified tumor biopsy techniques. With a probe carrier to the
Stereoadapter the biopsy target is simulated on a phantom base.
For surgery the Stereoadapter with probe accessory is
re-mounted on the patient. Under local anesthesia, tissue samples are then aspirated with a 2 millimeter Sedan-Nashold biopsy
cannula introduced through a twist drill hole. The same technique may be utilized in ventriculostomies and cyst
The arc-centered Stereoguide a conventional stereotactic frame with its Microdrive is designed to assist all forms of morphological and functional stereotactic surgical procedures.
|When the Stereoguide is used in combination with the Stereoadapter as CT/MRI localizer,
neither contrast enhanced ventriculography not stereotactic radiography are required. The Stereoguide is simply positioned in
relation to the Stereoadapter so that the target area coincides with the isocenter of the Stereoguide. The Stereoadapter is
removed before surgery is commenced. || |
||The target may be approached from any suitable direction. Multiple targets may be
reached through one centrally located burr hole simply by change of coordinate settings.
