First, the puncture is performed at the level of lumbar vertebrae L2/3 or L3/4 using a Tuohy cannula, followed by identification of the epidural space. The metal stylet of the Tuohy cannula provides for more stability, particularly in cases of special length. The outer cannula and the metal stylet are moreover produced and sharpened together so that the metal stylet ends flush with the cannula. This avoides with virtual certainty, that tissue fragments are introduced into the epidural space during the injection.
Puncture of the spinal space
In the second step, a SPROTTE® spinal puncture cannula is introduced through the Tuohy cannula. This cannula is used to puncture the subarachnoidal space and to perform spinal anaesthesia by administering a local anaesthetic.
The innovative Locking system
The SPROTTE® cannula can be locked in place completely with the new Locking system. The spinal cannula is thereby anchored in exactly the desired position in the Tuohy cannula. After that the steel stylet is retracted and the anaestetic can be administered.
