Caliburn trocar systemS

In vitrectomy with the OS 4, the Caliburn trocar system ensures precise work with exceptionally sharp instruments. The lance-shaped blade is distinguished by its high piercing and cutting force. The razor-sharp Caliburn blade reduces the penetration force and leads to an optimal cutting geometry in the sclera. The thin tunnel incision enhances postoperative wound sealing.

The trocar with integrated sealing membrane prevents the leakage of BSS, air and oil, resulting in a constant IOP. With its holding power and optimal shaft length, the Caliburn trocar offers both safety and convenience.

Advantages of Caliburn trocar systems:

Postoperative wound tightness
Smooth insertion of the trocar
Integrated, double-slotted sealing membrane for
constant IOP during surgery
Patented infusion tube with snap lock for increased
flexibility
