Why Holmium ?
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.
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 fibre tip
thus allowing the safe application also on
sensitive surfaces. Tissue more than 5 mm
apart from the fibre 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 characterised 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.
Operation of the Laser
The Sphinx Holmium laser is easy and safe to
use. The user is guided by
easy-to-understand menus. All settings of
the laser are displayed by coloured bar
graphs which can clearly be read even from a
distance. In addition, the user is supported
by acoustic signals. Unique features are the
vertical fibre port and the extendible fibre
support which ensure that the laser fibre is
guided to the operating area from above. Of
this arrangement, the freedom of action of
the operating is not affected. Uneven floors
and thresholds are easily passed because of
the system's large running wheels and an
independent wheel suspension. Considering
its mobility, the laser system is best
suited for service in multiple operating
theatres and mobile services.
Advantages
Adjustable laser pulse duration
In order to optimise the interaction with
various types of tissue the duration of the
laser pulse can be adjusted within the range
of 150 µs to 800 µs while the pulse energy
is kept constant. As a result, the laser is
not only used for the ablation of hard
tissue but also for almost bloodless cutting
of soft tissue. This makes the Sphinx
holmium laser system a versatile instrument
in surgery. While short laser pulses with a
high pulse peak power are more suitable for
the fragmentation of calculi and ablation of
hard tissue, long laser pulses are better
suited for cutting of soft tissue with
efficient hemostasis. This feature is an
unparalleled advantage compared with any
other Holmium laser on the market. The
adjustable laser pulse duration is
particularly advantageous for a
multi-disciplinary use of the laser system.
Programme memory
The Sphinx Holmium laser is equipped with a
specific programme memory allowing to save
up to 50 setting for individual
multi-disciplinary applications.
Reusable applicators and laser fibres
Special laser applicators and laser fibres
are available for the various medical
applications. To keep the running costs of
the Sphinx laser low, most of the
applicators and fibres are reusable and can
be steam sterilized. Please refer to the
Medical Accessories Brochure for details.
Integrated active cooling
The integrated active cooling allows long
time operation even at higher ambient
temperatures and produces less noise than
the competing products with radiators and
fans only.
