The ZD stereotactic system

Frame-based stereotactic neurosurgery with a classical and proven stereotactic arc

The inomed ZD frame was named after its developers, Prof. L. Zamorano and Prof. M. Dujovny and is most commonly used in neurosurgery and neuromodulation surgery.

The ZD system combines classic stereotaxic methods with the modern requirements of stereotactically guided microsurgery. The procedures involve stereotactic endoscopy, laser therapy and other state-of-the-art applications such as neuromodulation and stereotactic biopsy.

Precision engineering and manufacturing are uniquely combined with ease and intuitiveness of use in the design of the ZD frame. For this reason, the ZD system forms an important tool for the modern neurosurgeon. Minimally invasive neurosurgical techniques performed with the ZD frame provide both patient-friendly and life-sustaining treatment options for diseases of the brain.

Almost unrestricted access to all intracranial regions

Based on the center-of-arc principle, the ZD system provides almost limitless access to all intracranial regions, allowing the entry point to be freely selected. The surgeon can choose the entry point providing the greatest safety for the patient, ensuring that all settings for neuromodulation on the ZD system are configured with the highest mechanical precision.

The ZD system supports all imaging modalities used for advanced therapy requirements, including DBS. The titanium ZD head ring unit guarantees artifact-free CT and MR images. The head ring is completely transparent to X-rays as well. The modular design of the ZD system allows a range of diagnostic and therapeutic stereotactic procedures and neurosurgery to be accommodated quickly and easily while being performed precisely and safely. This applies to DBS procedures in the field of neuromodulation as well as to stereotactic biopsy of the brain.
