[A new apparatus and stereotactic method for percutaneous high cervical cordotomy]

Area of Science:

• Neurosurgery
• Medical Device Engineering

Context:

• Intractable pain management often requires invasive procedures.
• Percutaneous high cervical cordotomy is an established treatment for severe pain.
• Previous methods may involve significant radiation exposure.

Purpose:

• To introduce a novel stereotactic apparatus for percutaneous high cervical cordotomy.
• To improve the accuracy and safety of the cordotomy procedure.
• To potentially reduce radiation exposure for patients.

Summary:

• The apparatus features a head and neck holder for neutral positioning and a stereotactic guide and marker system.
• The system allows for precise needle insertion and target localization using cervical X-ray, without requiring an image intensifier.
• Designed for bilateral use, enhancing procedural flexibility.

Impact:

• Facilitates stereotactic guidance for percutaneous cordotomy.
• Enables accurate needle placement even without advanced imaging.
• Offers a method to minimize X-ray exposure during cordotomy procedures.
