potential applications of ultrasonic
instruments are greatly extended by
surgeons and natural scientists in cooperation
with Söring:

• Laparoscopic rectum resection
• Hernia
• Partial liver resection
• Hemorrhoidical tissue
Gynaecology
• Tumour resection
• Adhesiolysis
• Laparoscopic ovarectomy
• Myoma extirpation
• Cyst extirpation
• Myoma/polyp resection
• Hysteroectomy
Urology
• Prostataectomy
Ultrasonic-Hook Application
Introduction
Via a piezo ceramic system in the handpiece, the microprocessor-controlled
generator converts electric energy into mechanic energy.
The blades located on the distal instrument tip perform an axial oscillation
at frequency of 55 kHz. The deflection reaches ranges between 10
and 100 micrometers. Power adjustment to the ultrasound instruments
is available in four presets or continuously on the generator.
Providing different functions the Söring ultrasonic instrument system
provides these effects:
Cavitation: Cavitation requires a high degree of colloidal water contents
in the tissue. When the cavitation threshold of ca. 30mW/mm 2 is exceeded,
cavity bubbles imploding due to the high vacuum and transferring
their kinetic energy as a pressure shock to the immediate environment
are formed in the parenchymatous tissue.
Coagulation: Energy applied to the instrument tip for a longer period
of time causes a temperature rise, which results in a denaturation and
coagulation. Temperatures of up to 200° Celsius can be reached.
Cutting: By applying additional tension or pressure the oscillations of
the distal instrument tip result in the grasped tissue´s elasticity limit being
exceeded and thus cuts.
Benefits of ultrasound technology
• No formation of smoke to obstruct view
• Precise cutting depth and dosage
• Limited lateral tissue damage
• No carbonization, almost complete denaturation;
temperature higher than 65° Celsius, but less than 200° Celsius
• Full protection against burns
• No neuromuscular stimulation
• Pure ultrasonic energy
• No electricity to body
Operating the Söring US-Scissors and US-Hook
Ease of set-up to manipulate the cutting and coagulation effects:
• Double foot switch
red=100 % / black=set value, (e.g. 50%)
• The duration the tissue remains on the ultrasonic knife
(see right insert 1)
• The mechanic tension exerted on the tissue (see right insert 2)
• User adjustable US power
Exerting tension on the tissue held by the ultrasonic knife can attain a
cutting effect only! To cut, keep the tissue under pressure with the
scissors jaw.
• For fast cutting, limited coagulation
use 100% ultrasound with tension and strong pressure
• For delayed cutting with maximum coagulation
use 50% ultrasound, only limited tension and slight pressure
A coagulation effect can be attained by exerting light pressure, but no
tension on the tissue held by the ultrasonic knife.
• Good coagulaton with ca. 40 to 60% power switched on
with the black foot switch.
• You can increase the coagulation effect by rotating the ultrasonic
instruments to the right and to the left (with the tissue held by the
ultrasonic knife).
Note: Coagulation occurs by means of the thermal effect only. Because
of the mechanic energy/activity the oscillating ultrasonic knife tip generates
heat. This heat causes a tissue denaturation (temperature over 65° -
~200° Celsius). The oscillating ultrasonic knife (55 kHz) is blocked when
the moving scissors jaws exert pressure on the grasped tissue.
An incidental delayed cutting effect cannot be avoided.
Economical and thrifty
Cutting effect
Apply strong pressure
to hold the tissue,
then switch on
ultrasound and exert
tension on the tissue.
Setting: 100% >
red footswitch pedal, or lower power
setting with the black footswitch
pedal.
Coagulation effect
Apply light pressure to
hold the tissue, then
switch on ultrasound
but do no exert
tension on the tissue.
This results in a thermal
effect on the tissue.
Setting: 40-60% > black footswitch
pedal. When coagulation is visible, you
can revert to the cutting effect to cut
the tissue.
