A new fixation device for the Leksell stereotaxic system. Technical note.

Area of Science:

• Neurosurgery
• Medical Devices
• Stereotaxy

Background:

• The Leksell stereotaxic system is a cornerstone in neurosurgical procedures.
• Existing systems may have limitations in maintaining spatial orientation during complex interventions.
• Accurate patient fixation is critical for the success of stereotactic procedures.

Purpose of the Study:

• To introduce a novel fixation device for the Leksell stereotaxic system.
• To enable versatile applications including radiosurgery and microsurgery.
• To enhance the precision and reusability of stereotactic procedures.

Main Methods:

• A rectangular instrument was developed to connect with the Leksell stereotaxic coordinate frame.
• The device ensures maintained spatial orientation even after frame removal.
• Compatibility with imaging modalities like CT and MRI was assessed.

Main Results:

• The device allows for precise and repeatable patient fixation.
• It facilitates stereotactic radiosurgery and microsurgical guidance.
• An accessory for animal stereotaxis was also developed.

Conclusions:
