Function:

Cuttig: The high-frequency vibrations of the active blade cause tissue to vibrate and break apart, allowing for precise and controlled incisions.

Coagulation: The heat generated by the ultrasonic vibrations denatures proteins, causing blood vessels to seal and preventing excessive bleeding.

Dissection: The ultrasonic scalpel can be used for dissecting tissue plans and creating precise cuts for various surgical procedures.

Hemostasis: By sealing blood vessels as it cuts, the ultrasonic scalpel provides effective hemostasis, minimizing blood loss during surgery.

Features:

Ultrasonic Energy:The core of the ultrasonic scalpel's function is the use of ultrasonic energy, which is converted into mechanical vibrations.

Simultaneous Cutting and Coagulation: The device can cut and coagulate tissue at the same time, streamlining surgical procedures.

Minimal Thermal Damage:

Compared to electrosurgery, the ultrasonic scalpel produces less heat and minimizes thermal damage to surrounding tissues, leading to faster healing and reduced scarring.

Precise Control:

The surgeon has precise control over the cutting and coagulation process, allowing for intricate and delicate surgical maneuvers.

Reduced Smoke and Smell:

The harmonic scalpel produces less smoke and smell than electrosurgery, which can improve visibility and reduce the need for smoke evacuation.

Versatility:

The harmonic scalpel can be used in a variety of surgical specialties and procedures, including general surgery, laparoscopy, and ENT.

Safety Features:

Many models include safety features like automatic shut-off to prevent overheating and warning systems to alert the surgeon to potential issues.
