Clinical Guide
Lumenis recommends that physicians learn and gather additional
knowledge related to the Lumenis Pulse 120H. For details on courses and
training sessions available at Lumenis, contact your Lumenis
representative.
Lumenis does not make recommendations regarding the practice of
medicine. Laser presets are provided by the software operating system for
your convenience. Individual treatment should be based on clinical
training, clinical observation of laser-tissue interaction, and appropriate
clinical endpoints.
WARNING:
Unauthorized use of this system may expose the operator/patient to
potential electrical energy and laser radiation hazards.
NOTE:
The Lumenis Pulse 120H system is furnished with predefined parameter
sets of treatment parameters, called
Lumenis Presets
. These presets are
based on successful results obtained by experienced physicians using
Holmium laser systems.
The Ho:YAG wavelength has been shown to be a safe and effective tool
for the ablation, vaporization, incision, excision, and coagulation of a
variety of soft tissues. This has been demonstrated by both clinical and
preclinical studies. The 2100 nm wavelength of the holmium laser is
highly absorbed by water (absorption peak of water: 1940 nm). The
absorption of the laser energy by water produces an energy density that
heats the tissue to greater than 100°C thus vaporizing or ablating the
tissue without deep coagulation, allowing for precise incision (cutting)
and excision (dissection) when in direct contact with the tissue. When the
laser is not in direct contact with the tissue, the produced heat can
dissipate, leading to coagulation of vessels to a depth of up to 3 mm.
Effect on Soft Tissue
The depth of the incision is determined by the amount of energy (in
Joules) applied. The rate at which the incision is made is dependent upon
the rate of energy pulses being delivered to the target tissue (in pulses per
second, or Hertz). Optimum incision of tissue is accomplished by
balancing the depth of the incision and the rate at which the incision is
being formed. The physician may control both the energy setting and the
