A new head clamp for stereotactic and intracranial procedures. Technical note

Area of Science:

• Neurosurgery
• Medical Devices
• Surgical Technology

Background:

• Stereotactic procedures require precise head fixation for accurate electrode or instrument placement.
• Existing methods for head immobilization may present limitations in rigidity or versatility.

Purpose of the Study:

• To introduce a novel head clamp designed for secure head fixation during stereotactic neurosurgery.
• To highlight the advantages of rigid head immobilization for various neurosurgical applications.

Main Methods:

• Development and application of a specialized head clamp for surgical table integration.
• Utilizing the clamp for stereotactic frame fixation, percutaneous trephination, and X-ray centering.
• Employing the device during ventriculography, pneumoencephalography, and epidural screw placement.

Main Results:

• The head clamp ensures rigid immobilization of the head, crucial for stereotactic accuracy.
• Facilitates multiple neurosurgical tasks including frame fixation, skull trephination, and contrast agent manipulation.
• Demonstrates utility in both stereotactic procedures and craniotomies for head fixation and retractor support.

Conclusions:

• The devised head clamp offers significant advantages in achieving stable head fixation for stereotactic and other neurosurgical interventions.
• Its versatility supports a range of critical steps in complex brain surgeries, enhancing procedural outcomes.
