Caspar Nerve Root Retractors are precision microsurgical spinal instruments designed to cradle and displace delicate nerve fibers during lumbar disc operations. Featuring a 9 ½″ (24.13 cm) reach, specialized downward-curved tips, and selectable blade widths from 4 mm to 10 mm, they prevent accidental instrument trauma to the thecal sac.
Product Description
Caspar Nerve Root Retractors are essential spinal microsurgery instruments engineered specifically to provide safe, non-traumatic mobilization and shielding of the dural sac and spinal nerve roots during posterior lumbar decompressions. Designed with an elongated 9 ½-inch (24.13 cm) reach, these instruments allow spine surgeons to work comfortably in deep interlaminar corridors without obstructing the microscopic view.
Built for delicate neural protection, the Caspar Nerve Root Retractors series features specialized downward-curved blade tips engineered to cradle nerve roots smoothly, preventing them from slipping back into the operative window or suffering injury from high-speed burrs and rongeurs. The series is offered in four standardized blade widths: 4 mm ($84), 6 mm ($89), 8 mm ($94), and 10 mm ($99). The ergonomic flat handle incorporates fine tactile serrations that grant the operating surgeon exceptional micro-manipulation control.
Machined from medical-grade surgical stainless steel with a reflection-free satin matte finish, Retractor Maker produces Caspar Nerve Root Retractors to strict clinical tolerances, ensuring high corrosion resistance, unyielding structural rigidity, and complete autoclave durability for neurosurgical and spine centers worldwide.

Frequently Asked Questions
What are the blade and handle design advantages of the Caspar Nerve Root Retractors?
The Caspar Nerve Root Retractors is a solid one-piece instrument, so its performance comes from blade geometry and handle ergonomics. The working blade is specified as 4 mm ($84.00), 6 mm ($89.00), 8 mm ($94.00), 10 mm ($99.00), which spreads retraction force over a wider contact area and reduces point pressure on tissue. The handle is ergonomic flat handle with lateral tactile grip grooves, giving a secure, fatigue-resistant grip through long exposures. An overall length of 9 ½″ (24.13 cm) extended reach keeps the surgeon's hand clear of the operative field. It is made from surgical-grade stainless steel (aisi 304/420) for glare-free, corrosion-resistant service.
What are Caspar Nerve Root Retractors used for?
Caspar Nerve Root Retractors are used in posterior spine surgery to mobilize the traversing and exiting nerve roots and dural sac medially, protecting them during disc excision, burring, and interbody fusion.
Which surgical procedures are they for?
They are indicated for lumbar microdiscectomy, minimally invasive TLIF, PLIF, hemilaminectomy, foraminotomy, and revision spinal canal decompression.
What material and finish are used?
The instruments are forged from premium surgical-grade stainless steel with an anti-glare satin matte finish that eliminates optical reflections under operating microscopes.
Are Caspar Nerve Root Retractors reusable and autoclavable?
Yes. All Caspar Nerve Root Retractors are 100% reusable and fully validated for pre-vacuum steam autoclave cycles (134°C / 273°F).
Can components and blades be ordered separately?
Because this is a solid, one-piece handheld instrument, each blade width is sold as a standalone unit. Hospitals can order complete multi-size sets to stock specialized spine microsurgery trays.
Can custom modifications or private-label markings be ordered?
Yes. Retractor Maker provides custom blade widths, modified shaft curvatures, and laser marking for hospital asset tracking upon request.
What is the standard lead time and delivery timeframe for orders?
In-stock instruments take 5 business days to inspect and dispatch, followed by 7 business days for worldwide express delivery. Back-order units take 17 to 20 business days to manufacture and 9 business days for delivery.
