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When the cannula has been withdrawn, the multi-layered dura, consisting of collagens and elastic fibres, closes again.
