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.
