Mode of operation
Principle of ultrasonic cleaning
TRISON ultrasonic baths use the e
ff
ect of cavitation. They contain piezoelectric
transducers under their tank bottoms and additionally on the tank wall, the energy of
which is transferred to the bath liquid as mechanical oscillations at ultrasonic frequency.
As a result, microscopically small bubbles are continuously formed in the bath liquid,
releasing energy upon imploding and generating local microcurrents. This process
is called cavitation. During the cleaning process, this causes contamination to be
positively blasted from the hard surfaces of the objects being treated. At the same time,
dirt particles are dispersed and fresh bath liquid
fl
ows in.
TRISON ultrasonic baths are e
ffi
ciently supported by SweepTec automatic frequency
control. SweepTec immediately balances load-dependent working point
fl
uctuations
using fast frequency modulation around the optimal working point. This produces an
especially homogeneous and uniform ultrasound
fi
eld in the bath volume for constantly
reproducible results.
Cleaning, rinsing and movement of robotic instruments in the TRISON Twist
On the TRISON Twist, up to 4 robotic instruments with diameters of 5 or 8 mm can
be rinsed on the inside and simultaneously moved at their tips during sonication.
The instruments are snapped onto the TRISON Twist and each of them is connected
through two hoses to the TRISON Base's rinsing circuit.
The cleaning program
fi
rst conducts a
fi
lling and soaking of the instruments for 30
minutes, using a cleaning agent, in order to loosen up or dissolve organic residue. The
control housing and shaft of each instrument are rinsed and tested for
fl
ow-through in
subsequent ultrasonic cleaning. Instruments that were not rinsable during the cleaning
process, e.g. due to clogging, are reliably identi
fi
ed by the integrated continuity test and
speci
fi
ed on the monitor.
The sonication time is permanently programmed for 30 min.
Cleaning and rinsing of MIS instruments/cleaning of standard instruments in the
TRISON Rack
During sonication, up to 8 rinsable MIS instruments with exterior diameters of 3 to 10
mm can be rinsed from the inside in the TRISON Rack. Each instrument is hooked up
to its assigned adapter and connected to the rinsing cycle of the TRISON Base. Rinsing
is conducted using a suction process at the distal end of the instruments. Soiling is
always evacuated in the direction opposite to that in which it entered. The remaining
lumen of the respective instruments is not contaminated any further by this soiling. The
interior of the shaft of every instrument is rinsed and tested individually for
fl
ow-through.
Instruments that were not rinsable during the cleaning process, e.g. due to clogging,
are reliably identi
fi
ed by the integrated continuity test and speci
fi
ed on the monitor.
"Non-continuity" of an instrument is declared if the
fl
ow-through rate is less than 2 ml/s.
