Medtronic 963-721 3-Inch Fixation Pin for Spine Stealth Station System 5"

Medtronic StealthStation™ Fixation Pin | 3" Working Length | 963-721 | Reusable

The Medtronic 963-721 is a high-precision orthopedic fixation pin specifically engineered for use with the StealthStation™ Surgical Navigation System. In image-guided spine surgery (IGS), maintaining a rigid, "zero-drift" connection between the patient's anatomy and the navigation reference frame is the single most critical factor for accuracy. This fixation pin provides that stable anchor point, typically securing the reference array to the spinous process or the iliac crest.

With a 3-inch working length and a 5-inch overall length, this pin is designed to clear deep layers of soft tissue and paraspinal musculature, ensuring the navigation array remains visible to the optical cameras throughout the duration of the procedure.

Technical & Clinical Advantages

• Rigid "Zero-Drift" Stabilization: The 963-721 features a threaded distal tip designed to achieve high-torque purchase in cortical bone. This ensures the navigation reference frame does not shift during instrument changes or accidental contact, preserving sub-millimeter navigation accuracy.

• Extended Soft-Tissue Clearance: The 5-inch overall length allows the surgeon to anchor the pin deep within the surgical site while keeping the navigation array elevated above the wound edges and surgical retractors.

• Medtronic Stealth™ Integration: Specifically calibrated to interface with Medtronic’s universal reference frames and clamps. The shaft diameter is precision-machined to prevent "vibration" or loosening within the clamp mechanism.

• High-Tensile Stainless Steel: Forged to resist bending or bowing under the weight of the navigation array. This material integrity is vital for ensuring that the spatial coordinates remains consistent from the initial registration through the final implant placement.

• Tapered Trocar Tip: Engineered for efficient bone penetration with minimal risk of splintering, providing a secure "bite" into the spinous process or posterior superior iliac spine (PSIS).

Applications

• Spine Surgery: Anchoring the navigation reference frame for pedicle screw placement, laminectomy, or tumor resection.

• Iliac Crest Fixation: Serving as a primary reference point for complex pelvic or multi-level lumbar reconstructions.

• Neuro-Navigation: Specialized cranial applications requiring rigid skeletal fixation of tracking arrays.

Condition & Quality Assurance

• Status: Used – Good Usable Condition.

• Maintenance: This instrument shows visible signs of professional use (minor surface scuffs or cosmetic "tray wear" consistent with standard hospital processing), but it remains fully functional. The threaded tip is sharp and intact, the 5-inch shaft is perfectly straight, and the stainless steel is free of pitting.

• Professional Standards: With over 25 years of experience in surgical navigation and hospital materials, Primis Medical ensures all Medtronic Stealth™ accessories are function-verified and ultrasonically cleaned prior to shipment.

Shipping & Handling

• Secure Logistics: Shipped in protective, rigid packaging to ensure the distal threads and axial alignment remain in factory-standard condition during transit.

• Fast Dispatch: Ships within 1 business day.
