A Stencil Instrument for Countersinking Deep Brain Stimulator Lead Anchoring Devices.

Area of Science:

• Neurosurgery
• Medical Devices
• Surgical Techniques

Background:

• Deep brain stimulator (DBS) lead anchoring devices can cause scalp erosion and poor cosmesis.
• Effective countersinking of these devices is crucial for patient outcomes.
• Current methods may be time-consuming or lack precision.

Purpose of the Study:

• To introduce a novel, handheld surgical stencil instrument for countersinking DBS lead anchoring devices.
• To demonstrate the instrument's utility in reducing surgical time and improving the fit of the anchoring device.
• To highlight the benefits of improved countersinking for reducing complications and enhancing cosmesis.

Main Methods:

• The article describes a dual-sided, handheld surgical stencil.
• One side facilitates a full-thickness circular burr hole.
• The other side enables partial-thickness craniotomy for precise countersinking of the anchoring device base ring.

Main Results:

• The described instrument simplifies the countersinking procedure.
• It ensures a tight contour around the anchoring device base ring.
• The use of the stencil is associated with reduced risk of scalp erosion and improved cosmetic results.

Conclusions:

• The handheld surgical stencil is an effective tool for countersinking DBS lead anchoring devices.
• This method improves surgical efficiency and patient cosmesis.
• The instrument offers a practical solution to minimize complications associated with DBS hardware.
