Diagnostic lumbar puncture with SPROTTE® cannulas

The Lumbar puncture is an indispensable instrument for diagnostics and therapy control of inflammatory and oncological diseases of the central nervous system. The PAJUNK® atraumatic SPROTTE® cannula sets standards for the security of the invasive intervention.

Characteristics of the SPROTTE® cannula

• The closed, ogive-shaped tip displaces tissue during puncture rather than cutting it, as is the case with Quincke cannula tip
• The lateral eye has rounded edges
  is sealed precisely by the stylet during puncture¹
  produces excellent sliding properties and minimizes the transfer of foreign bodies and tissue particles into the spinal canal
• The cannula is made of high-quality medical-grade stainless steel with polished surfaces that are free from burrs

Ogive-shaped tip geometry displaces tissue during puncture, causing minimal injury.²
When the cannula has been withdrawn, the multi-layered dura, consisting of collagens and elastic fibres, closes again.
