Ergonomic Handle Grip Harmonic Ultrasonic Surgical Scalpel
Laparoscopic Surgery Harmonic Ultrasonic Surgical Scalpel
The harmonic scalpel is a surgical instrument used to
simultaneously cut and cauterize tissue. It is the latest device to
have been introduced in last decade or so. Ultrasonic energy is
famously used in Harmonic scalpel where ultrasonic energy is
converted to mechanical energy at the active blade. The main
mechanism is the active blade which delivers high-grade frictional
force while the inactive upper arm holds tissue in apposition. Its
main advantages include precise dissection, reliable hemostasis,
less lateral thermal spread and charring mainly works by applying
pressure and then sealing with a denatured protein coagulum while
applying ultrasonic vibration to denature hydrogen bonds perform
vessel coagulation.
Ultrasicon is the name given to the dissection method by harmonic.
The transducer in the handpiece consisted of piezoelectric crystal
sandwiched under pressure among metal cylinders. The ultrasonic
generator converts ultrasonic energy into mechanical energy. The
sealing of the vessels is achieved due to denatured protein
coagulum which occurs due to tamponade and coaptation. It has three
compatible probes that are the shear, blade and a hook. The shear
can coagulate vessels up to 5 mm, whereas the hook and blade only 2
mm in diameter. It has the least thermal spread and smoke
production of all the devices.
Indications
The Harmonic Scalpel System is indicated for soft tissue incisions
when bleeding control and minimal thermal injury are desired. The
System instruments can be used as an adjunct to or substitute for
electrosurgery, lasers, and steel scalpels.

Operation
Refer to a compatible Harmonic Generator User Manual for hand piece
attachment and system operation instructions.
1. Connect the assembled Hand Piece and instrument to the generator
and turn the generator power on. Do not turn the generator power on
before the Hand Piece and instrument are connected to the
generator.
2. Select the desired variable or minimum power level using the
INCREASE and DECREASE buttons on the generator.
Minimum starting power level defaults to power level 3. For greater
tissue cutting speed use a higher generator power level, and for
greater coagulation use a lower generator power level. The amount
of energy delivered to the tissue and resultant tissue effects are
a function of many factors, including the power level selected,
blade characteristics, grip force, tissue tension, tissue type,
pathology, and surgical technique.
MAX power is set at power level 5 and cannot be adjusted.
3. The HARMONIC Shears instrument may be operated with either the
foot switch or hand control. For foot switch or hand control
function, refer to a compatible Harmonic Generator User Manual for
further detail and setup and operation instructions.
4. For optimal performance, clean the instrument blade and clamp
arm throughout the procedure by activating the instrument tip in
sterile saline. The instrument can be wiped with a sterile moist
gauze sponge to remove tissue, if necessary.
WARNING: Do not touch the instrument to metal while activated. See
Warnings and Precautions.
5. If tissue is still visible in the clamp arm, use hemostats to
remove residue.
6. The blade is ultrasonically energized when either the foot
switch pedal is depressed or one of the hand controls is depressed.
Pressing either the left foot pedal of the foot switch or the
proximal hand control (MIN) on the instrument activates the
selected minimum power level.
Pressing either the right foot pedal of the foot switch or distal
hand control (MAX) on the instrument activates the maximum power
level.
The generator provides an audible tone to indicate when the
instrument blade is active.
The generator changes to a second activation tone as Adaptive
Tissue Technology regulates the delivery of energy.
Thermal influences such as fluids or minimal to no tissue in the
jaws may affect the presence or timing of the tone change.
The tone change does not provide confirmation of tissue effect.
When the second tone is heard, the situation should be assessed and
the intended surgical action completed, such as gradual application
of tension to facilitate transection.
The secondary activation tone change is not a substitute for
surgical experience.
WARNING: Avoid accidental contact with other instruments during
use. Scratches on the blade may lead to premature blade failure.
See Warnings and Precautions.
