Mayfield Skull Clamp System for Cranial Fixation

A Mayfield Skull Clamp is a specialized cranial fixation system used to provide rigid, 3-pin head immobilization during neurosurgery, spine surgery, ENT, and ophthalmic procedures. By anchoring directly into the cranial bone using single and double-pin rocker arms, the clamp holds the patient’s head completely stationary throughout delicate interventions.

Our Mayfield Skull Clamp system features a calibrated 360 N (80 lb) torque screw mechanism, 360-degree horizontal rotation, and a ball-pivot swivel adapter. It connects to standard operating table side rails and base units, securing the skull without movement during high-magnification microneurosurgery. We manufacture this complete cranial fixation unit from CNC-machined, high-strength aluminum alloy at our facility in Pakistan, supplying direct wholesale shipments to international hospitals, distributor networks, and OEM brand partners.

What Is the Mayfield Skull Clamp?

The Mayfield Skull Clamp is a heavy-duty surgical head holder designed for cranial stabilization. Rigid head immobilization is critical when operating near brain parenchyma, spinal cord structures, and major cranial vessels, where even sub-millimeter shifts can compromise surgical outcomes.

The clamp uses a three-point pin contact framework: a single pin on one arm and a dual-pin swivel rocker on the opposing arm. This arrangement distributes mechanical compression force evenly across the skull. The unit features a quick-release locking mechanism and an adjustable base extension, allowing surgical teams to position patients safely in prone, supine, lateral, or sitting orientations.

Key Features

• Rigid Three-Point Pin Fixation: Equalizes pressure across the cranium using a single pin and a dual-pin rocker arm.

• Calibrated Torque Screw: Delivers precisely measured clamping force up to 360 N (80 lb) to prevent over-tightening or slippage.

• CNC-Machined Aluminum Alloy: Milled entirely from solid high-strength aluminum blocks with zero cast metal parts to ensure structural integrity and reduce overall frame weight.

• Full Multi-Axis Articulation: Offers 360-degree horizontal rotation and 0° to 90° longitudinal adjustment via a ball-pivot swivel adapter.

• Adjustable Base Extension: Base width adjusts from 190 mm to 560 mm to fit standard operating table base units.

• Quick-Release Locking System: Enables rapid disengagement and smooth intraoperative adjustments.

• Flexible Patient Positioning: Accommodates prone, supine, lateral, and sitting positions.

• Soft Headrest Integration: Compatible with gel and silicone headrest pads for non-pinned patient positioning when rigid fixation is not required.

• Universal Interface: Designed to fit standard operating room table adapters and works alongside Mayfield®-style and DORO®-style accessories.

Mayfield Skull Clamp Components Explained

Standard Mayfield Skull Clamp System

The main clamping framework consists of an adjustable ratchet extension arm, a dual-pin rocker arm, a single-pin torque arm, and a ball-pivot swivel adapter. The three-pin setup creates a rigid structural bridge between the patient’s cranium and the operating table base. It keeps the head steady under pressure from surgical drills, ultrasonic aspirators, and heavy retraction frames.

Extra Skull Pins

The system includes two spare skull pins to ensure operating teams have clean, sharp replacements ready. Fixation pins are available in stainless steel or titanium for adult and pediatric applications. Sharp pin tips penetrate the scalp to engage the outer table of the skull securely without slipping.

Aluminum Sterilization Box with Silicone Mat

The high-grade aluminum sterilization box features a custom silicone mat with dedicated component brackets. It holds the clamp arms, swivel adapter, and pin containers in place during transport and automated washing. Perforated panels ensure thorough steam penetration during pre-vacuum autoclaving while protecting delicate joint threads from impact damage.

How the Mayfield Skull Clamp Works

1. Patient Preparation: The patient is anesthetized, and the scalp entry points are prepared according to surgical protocol.

2. Pin Selection: The surgical team selects adult or pediatric pins based on patient age and bone thickness. Pins are mounted into the single-pin arm and the dual-pin rocker arm.

3. Primary Application: The clamp arms are extended around the skull. The two pins on the rocker arm are placed against the cranium first to establish a stable two-point plane.

4. Torque Application: The single-pin arm is advanced on the opposite side. The surgeon turns the calibrated torque screw clockwise until the visual torque indicator reaches the target force (typically 360 N / 80 lb for adult patients).

5. Table Mounting: The clamp’s base extension rod is inserted into the table’s transitional swivel adapter.

6. Final Trajectory Adjustment: The surgeon adjusts the patient’s head angle using the 360-degree swivel joint and 0°–90° longitudinal pivot, then tightens the main locking handle to secure the assembly.

Head Positioning Options

Rigid cranial fixation adapts to various surgical approaches:

• Prone Position: Used for posterior fossa craniotomies, occipital lesions, and posterior cervical spine surgery.

• Supine Position: Used for frontal, pterional, temporal, and anterior skull base procedures.

• Lateral Position: Used for retrosigmoid approaches, subtemporal corridors, and temporoparietal tumor resections.

• Sitting Position: Used for select supracerebellar infratentorial and pineal region procedures, providing gravity-assisted venous drainage and clear visibility.

Adult and Pediatric Configurations

• Adult Fixation: Recommended for patients over five years of age with mature cranial bone thickness. Standard adult pins apply up to 360 N (80 lb) of pressure.

• Pediatric Fixation: Used for younger pediatric patients with thinner cranial bones. Specialized pediatric pins and reduced torque settings (typically 180 N / 40 lb) prevent bone penetration or skull depression while maintaining frame stability.

Clinical Applications and Specialties

The Mayfield Skull Clamp provides stable immobilization across surgical disciplines:

• Brain Tumor Surgery: Holds the head rigid during high-speed craniotomies and delicate tumor resections under operating microscopes.

• Skull Base Surgery: Prevents movement during deep corridor dissections around cranial nerves and the brainstem.

• Cerebral Aneurysm Surgery: Eliminates micro-movement during vascular dissection and aneurysm clip application.

• Functional Neurosurgery: Maintains precise spatial registration during stereotactic frame placement and deep brain stimulation (DBS) electrode insertion.

• Microvascular Decompression (MVD): Stabilizes retrosigmoid positioning for micro-dissection of the 5th, 7th, and 8th cranial nerves.

• Cervical Spine Surgery: Secures the head during anterior cervical discectomy and fusion (ACDF) or posterior cervical stabilization.

• ENT & Ophthalmic Surgery: Holds the skull steady during complex skull-base ENT procedures and orbital microsurgeries.

Advantages of the Mayfield Skull Clamp

• Secure Cranial Fixation: Three-point pin contact eliminates head drift under heavy surgical forces.

• Precise Torque Control: The calibrated torque knob prevents skull over-compression and ensures consistent clamping force.

• Clear Working Field: The slim frame design leaves ample space for mounting table-anchored retractor systems, such as the Greenberg Retractor, Greenberg Simplicity Retractor, or Leyla Retractor.

• Durable Construction: Machined from solid aluminum blocks without cast components, preventing frame flexing under load.

• Simple Maintenance: Solid surfaces and anodized coatings resist corrosion and withstand automated washing and high-temperature autoclaving.

Cleaning and Sterilization

1. Pre-Rinsing: Rinse the clamp immediately after surgery with neutral-pH enzymatic detergent to prevent blood from drying inside the ratchet channels and swivel joints.

2. Disassembly: Open the quick-release lock, remove the skull pins, and separate the base extension from the swivel adapter.

3. Ultrasonic Cleaning: Process disassembled components in an ultrasonic bath to remove debris from internal ratchet teeth and thread tracks.

4. Inspection & Lubrication: Inspect pin sockets and ratchet locks for wear. Apply a water-soluble instrument lubricant to moving joint threads.

5. Steam Autoclaving: Place the clamp into its aluminum sterilization box with the silicone mat. Autoclave using pre-vacuum steam sterilization parameters (134C to 273F for 4 to 5 minutes).
