Needles for Atraumatic Lumbar Puncture

Together with Pajunk, Prof. Sprotte developed the Sprotte, the first atraumatic needle for lumbar Puncture. The secret of its success can be found in its unique tip geometry and basic architecture. This design, developed especially for the requirements of dural puncture, allows for an atraumatic puncture of the ligamentary structures and optimises CSF flow while reducing the incidence of post-lumbar puncture headaches (PLPH). Sprotte decreases complications of Lumbar Puncture and increases the safety of application, and the efficiency of diagnostics.

Sprotte® Lumbar Overview

Sprotte® Lumbar Features & Advantages

1. Atraumatic Tip Design

  • The ogive shaped tip significantly reduces the risk of PLPH and the rounded edges of the lateral eye minimise trauma to the dura mater.
  • Minimises chance of PLPH1, 2, 4, 5, 6, 7, 8
  • Consistent tactile feedback

2. Lateral Eye

  • Burr-free, rounded atraumatic edges
  • Optimised gliding properties
  • Minimum chance of tissue coring and carry-over into the subarachnoid space10

3. Optimal Lateral Eye Size and Placement

  • Unobstructed backflow, even if the eye is partially blocked by the arachnoid membrane
  • Allows for quicker CSF flashback9

4. Precision-Ground Metal Stylet

  • Lateral eye closes precisely to minimise chance of tissue coring10
  • Polished, rounded tip prevents abrasion on the inner needle tube

5. Highest Processing Quality

  • High quality stainless steel needle for increased stability
  • Smoothly polished and burr-free surface and inner lumen desgined for optimised gliding properties and CSF backflow
  • Consistent feel and reliable performance

6. Standard Hub

  • Designed for rapid detection of even the smallest quantities of CSF
  • Reduced Inner Space

7. Magnifying Hub (Only NRFit®)

  • Clear, magnifying needle hub allows for easy visualisation of blood or CSF.
  • Easier detection of CSF flashback

8. Colour-Coded Needle Hub with Size Indication

  • Easy identification of needle size

9. Introducer with Facet Tip

  • Diameter and length perfectly matched to each lumbar needle size
  • Minimal reduction of useable working length of the lumbar needle
  • Funnel-shaped hub to reduce chance of lumbar needle tip damage during insertion

10. Portfolio Excellence

  • Wide needle range with different diameters and lengths
  • Special designs for pediatrics and obese patients
