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. Endoscope lenses remain free from splatter when used in open surgery or in laparoscopy.

What Is the 2 Micron 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 or Diode 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 or disposable flexible fibres – ideal for endoscopic, laparoscopic and minimally invasive surgery.
Why 2 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 at this wavelength 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 laser power capacity allows high vaporisation and resection rates at no bleeding and short theatre time.
Absorbtion spectra of body chromophores
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 hemoglobin the KTP laser at 532 nm experiences close to no absorption. At the KTP wavelength water as the main body constituent is almost transparent. Under laser treatment hemoglobin 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 nor hemoglobin 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 hemoglobin water retains its absorptive properties under the temperature increase in tissue caused by the laser. This explains the everlasting ablation efficiency during RevoLix treatment.
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.
How Does RevoLix Match With Your Theatre?
The laser is extremely user friendly. RevoLix does not cause noise strain to theatre personnel. Large castors allow easy handling of the small footprint laser system. Regular theatre utilities are sufficient. The laser operates from standard power outlet. Special installation for cooling water and electrical supply are not required. The laser has proven its extreme sturdiness during routine transportation between theatres and mobil healthcare services.
Operation of the Laser
The laser is easy and safe to operate. The menu is easy to understand. Operational modes such as continuous or pulsed (cw intermitted) are selected by push buttons. The power setting is adjusted with a large adjustment wheel. Large characters display the settings on the easy to read display.
Delivery Systems Perfected
LISA offers a wide range of specialised delivery systems. Please refer to the LISA Medical Laser Accessories brochure for various front and side firing fibres, laser applicators and reconditioning tools. Reusable front firing fibres are stripped and cleaved in preparation for the next case. Disposable front firing fibres are available for the treatment of BPH. All fibres match with the surgical instrumentation recommended and approved by LISA laser products.
Depending on your theatre infrastructure either reusable or disposable fibres may be economical advantageous. For the RevoLix laser both of these options are available to your choice. Beyond a straight purchase of a RevoLix laser there are billing schemes on offer which are based on your personal usage pattern. Please contact your local LISA laser products distributor for further details and opportunities.
