RevoLix - what is the 2micron cw revolution?

For the first time a surgical laser is available for soft tissue surgery which unifies all advantageous properties of existing laser principles in a single unit.

RevoLix combines the cutting and ablation advantages of the well known CO2 laser - but there is no need for an articulated mirror arm.

RevoLix  achieves excellent haemostasis like the Nd:YAG laser - but there is no risk of deep tissue penetration.

RevoLix provides excellent tissue vaporisation - but unlike the KTP laser without the observed significant decrease in efficiency caused by bleaching of the target chromophore.

RevoLix tissue effect is shallow like the Holmium laser - however there is no trauma produced by the laser and cutting edges are smooth and clean. In open surgery there is no splattering.

RevoLix laser radiation is delivered to the surgical site through multi-use flexible fibres- ideal for endoscopic, laparoscopic and minimally invasive surgery.

What are the advantages?

Cutting efficiency of soft tissue and haemostasis is superior to any known alternative. Tissue damage is restricted to less than 1 millimetre beneath the cut. RevoLix preserves excellent vision to the surgical site. There is no vision impairment due to bleeding, excessive bubble formation, tissue fragments or ruptured tissue. Unlike KTP the surgical situs is free of any visible laser glare. The colour neutral laser safety eyewear does not generate discolouration like KTP. Endoscope lenses remain free from splatter when used in open surgery or in laparoscopy.

RevoLix - why Two Micron continuous wave ?

The RevoLix wavelength at 2.0 micron is known for its suitability for resection and ablation, safe application in an aqueous medium and it generates excellent haemostasis. These excellent properties are due to the efficient absorption of Two Micron laser radiation by water which is ubiquitous in any tissue. At the RevoLix wavelength of 2.0 micron the absorption is 2.5 times stronger than at the Holmium wavelength providing even more precise cutting in soft tissue surgery. In soft tissue surgery efficient and even cutting combined with strong haemostasis is required. This is provided by the RevoLix laser in an unmatched manner. The RevoLix laser operates in a continuous wave mode and cuts and vaporises vascular and white tissue without deep penetration or uncontrolled necrosis. Clean cuts and excellent haemostasis are achieved by moving the beam across the surgical site. Generous Two Micron laser power capacity allows high vaporization and resection rates at no bleeding and short theatre time.

This graph shows the absorption of the most important body chromophores ( RED for blood, BLUE for water, BROWN for melanin) at different wavelengths. Depth of penetration is shown at the right. Laser wavelengths are vertical lines.

KTP: In the absence of haemoglobin the KTP at 532 nm experiences close to no absorption. At the KTP wavelength water as the main body constituent is almost transparent. Under laser treatment haemoglobin bleaches due to the temperature increase in tissue caused by the laser. This explains the ever decreasing ablation efficiency during a KTP treatment.

Diode: At 980 nm neither water not haemoglobin is a strong absorber. This explains the deep penetration at this wavelength.

RevoLix and Holmium: Both lasers are of similar wavelength which is selectively absorbed by the water molecule. Other than haemoglobin water retains its absorptive properties under the temperature increase in tissue caused by the laser. This explains the everlasting ablation efficiency during RevoLix treatment.

RevoLix - why is it safe ?

In an aqueous medium the laser effect to tissue is restricted to less than 2 millimetres in front of the tip of the fibre. Any tissue further afield is shielded of by the medium. The same mechanism is protecting tissue and organs adjacent to the cut. Any tissue more distant than 2 millimetre is unaffected by the RevoLix laser. Opposed to KTP this property eliminates the risk of unintentional tissue damage during laser surgery.
