What makes the new trocar different

High cutting force

High cutting force for smooth entry: The sharp, lance-shaped blade delivers high cutting force into the sclera and forms the foundation for smooth entry^*.

Bevelled cannula

Bevelled cannula for continuous penetration force: The bevelled trocar cannula support smooth insertion into the sclera to provide a controlled and continuous penetration force^*.

Integrated markings

Integrated markings for instant orientation: Tactile markings on the handle and an integrated incision marker gives you instant orientation. This lets you feel the alignment right away and identify the correct incision point at the pars plana in no time^*.

New product and packaging design

Sustainability: Designed with sustainability in mind, the new packaging and product design reduces waste by 30 % per trocar set^* ².

Essentials details

Factors that shape trocar placement

Bevelled cannula
for smooth insertion
The new trocar design combines a sharp, lance-shaped blade with a bevelled trocar cannula to support smooth insertion into the sclera. This interplay lets you feel a controlled and continuous penetration force^*.
Tactile markings
for instant orientation
Clear tactile markings on the handle let you immediately feel the correct orientation, eliminating the need for additional visual control under the microscope^*.
Incision marker for precise
3 mm and 4 mm markings
The integrated incision marker on the handle provides precise 3 mm and 4 mm markings. This helps you locate the correct incision point at the pars plana in no time.
Integrated self-sealing
to maintain IOP
The integrated self-sealing membrane with a 4-flap concept maintains IOP by preventing the leakage of BSS, air or oil. It also supports smooth instrument insertion and can be easily removed and reinserted when needed^*.
Infusion tube with
snap-lock connection
The convenient snap-lock connection allows flexible repositioning of the infusion tube during surgery. When connecting the infusion tube, a noticeable click confirms the reliable snap-lock connection^*.

Reduced penetration force

Up to 43 % less penetration force

The diagram illustrates how the Caliburn Trocar System achieves up to 43 % less penetration force compared to the previous Caliburn Trocar System. This reduction is based on the interplay of a sharp, lance-shaped blade and the bevelled design of the trocar cannula, supporting a noticeably smoother entry into the sclera^*.

More inflow

Up to 76 % more
inflow at 23G

The diagram shows how the Caliburn Trocar System provides 76 % more inflow at 23G compared to the previous Caliburn Trocar System. In combination with the high aspiration performance of the Continuous Flow Cutter, this supports stable intraocular pressure conditions during surgery^*.

FAQ

In a nutshell about trocar systems

Penetration force can be reduced through coordinated trocar blade and cannula design. In vitreoretinal surgery, the new Caliburn Trocar System combines a sharp, lance-shaped blade with a bevelled design of the trocar cannula, supporting smooth insertion with controlled and continuous penetration force and up to 43 % less penetration force at 23G versus the previous system ^*.

Smooth trocar insertion is supported by the interaction of blade geometry and cannula design. In retina surgery, the bevelled design of the trocar cannula allows the blade and cannula to glide through tissue in one seamless motion, supporting smooth and effortless insertion into the sclera ^*.

A self-sealing trocar helps maintain IOP by preventing leakage of BSS, air, or oil. In ophthalmic surgery, the integrated 4-flap membrane of the Caliburn Trocar System also supports smooth instrument insertion and can be removed and reinserted as needed ^*.

Orientation can be obtained with tactile guidance on the trocar handle. In vitreoretinal surgery, clear tactile markings on the Caliburn Trocar System let surgeons immediately feel knife and cannula alignment, reducing the need for additional visual control under the microscope ^*.

The correct pars plana incision point can be identified with an integrated incision marker. On the Caliburn Trocar System handle, precise 3 mm and 4 mm markings support fast localisation of the incision point ^*.

Selected innovations for vitreoretinal surgery

Constant flow for efficient vitreous removal
The Continuous Flow Cutter ensures continuous aspiration thanks to its permanently open port and up to 15'000 cpm, resulting in reduced traction on the retina.
See the finest tissue structures with Power LED Plus
With Power LED Plus, you can individually adjust both colour spectrum and light intensity to reveal even the finest tissue structures. Mix yellow and blue as desired to achieve high-resolution contrast viewing.
Configure the OS 4 Up with or without endolaser
Why compromise when you can customise? Whether you rely on the convenience of an integrated 532 nm endolaser or prefer the platform without laser functionality, the choice is yours.
