The Scoville-Haverfield Self Retaining Retractor is an articulated spinal retractor featuring downward-hinged shanks designed to clear optical corridors during laminectomy. Handcrafted from German stainless steel with a 150 mm spread, a 50 mm sharp claw blade, a 60 × 25 mm micro-toothed paddle, and a central screw lock ($339), it delivers unencumbered microscopic visualization.
The Scoville-Haverfield Self Retaining Retractor is a premier articulated neurosurgical and spine retractor system engineered specifically to provide deep, unobstructed paraspinal tissue displacement during complex lumbar laminectomies and spinal fusions. Designed with jointed, downward-hinged shanks, this instrument drops the mechanical chassis flat against the patient's body contours, keeping assistant handles completely out of the surgeon's microscopic line of sight.
Built to clinical framework specifications, this Scoville-Haverfield Self Retaining Retractor complete set ($339) provides up to 150 mm of horizontal track expansion spread. Handcrafted from German stainless steel, the modular system incorporates a detachable single sharp pronged lateral blade with a 50 mm operational depth to anchor securely beneath dense incision margins, alongside a detachable solid toothed lateral blade measuring 60 mm × 25 mm (25 mm wide × 60 mm long) outfitted with a micro-toothed secure tip to grip bone margins atraumatically. The integrated manual screw lock gear central thread mechanism provides an immutable open hold that eliminates assistant hand fatigue.
Forged with an anti-glare satin matte finish, Retractor Maker produces the Scoville-Haverfield Self Retaining Retractor to withstand repetitive hospital autoclave cycles, providing neurosurgical centers, orthopedic spine operating rooms, and trauma theaters worldwide with exceptional mechanical stability, corrosion resistance, and complete autoclave durability.
