Sphinx Holmium Surgical Laser

Why Holmium?

The ablative effect of the Holmium-YAG laser is based on the high absorption of the Holmium laser energy in water and in biological tissue containing water. The pulsed energy of the laser radiation is converted into heat within a depth of tissue of less than 0.5 mm, making it ideal for use in ablation processes.

Strong absorption – efficient ablation

The pulsed Two Micron laser radiation of the Sphinx Holmium laser is highly absorbed in water and in biological tissue. The laser energy is converted into heat within a depth of the tissue of less than 0.5 mm and thus used for ablation purposes by vaporisation of tissue.

Strong absorption – shallow penetration

In soft tissue surgery efficient vaporisation is achieved without deep penetration or uncontrolled tissue necrosis.

How Much Power?

Depending upon your application, LISA laser offers a range of four lasers starting at 30 watts, and increasing to 45 watts and 60 watts. Each of these units can be upgraded to the highest power available, 80 watts.

How important is pulse width?

If you are breaking stones, the shorter the pulse width the better. LISA laser has the shortest pulse width available at 150 microsecs.

Strong absorption – safe operation

In a hydrous solution, the range of the Holmium laser radiation is restricted to the volume immediately in front of the fiber tip thus allowing the safe application also on sensitive surfaces. Tissue more than 5 mm apart from the fiber is screened off by the hydrous solution and will be affected by the laser.

Short pulses – efficient stone fragmentation

Laser pulses as short as 150 µs make the Sphinx highly effective in the fragmentation of calculi and ablation of hard tissue. The Sphinx Holmium laser is characterized by an extraordinary intense pulse peak power of up to 15 kW.

Long pulses – excellent hemostasis

Long laser pulses of up to 800 µs provide an excellent hemostasis in soft tissue surgery.

If you are ablating or cutting, and need hemostasis, then a long pulse width is better. LISA laser also has the capability to increase the pulse width up to 800 microsecs.

The Sphinx surgical laser comes in the following variations:
