08
The ultrasonic scalpel system is suitable for laparoscopic, thoracoscopic, small incision assisted, and traditional open surgery operations. It is used for the treatment of various soft tissues. Cutting and coagulation are completed at the same time to ensure minimal lateral thermal damage to the tissue.

Medical ultrasonic transducer is a device that converts ultrasonic frequency electric energy into ultrasonic energy in ultrasonic processing equipment. Currently, there are two types of ultrasonic transducers that are widely used. The types of ultrasonic transducers are as follows:

What is a Harmonic Scalpel? What is the Purpose of a Harmonic Scalpel?
02
Harmonic scalpel is a scalpel that uses ultrasonic vibration to cut and cauterize tissues at the same time. It uses these vibrations to penetrate even very dense tissues, and in many operations, it is less invasive than standard scalpels. Its ability to cauterize, or seal the wound during the healing process can also usually reduce recovery time and can also make the procedure more efficient and accurate. However, this scalpel is more than just a knife. In most cases, it is also connected to ultrasonic sensors, generators, and foot pedals, but from a practical point of view, this is not very conducive to portability.

The working frequency is the resonant frequency of the piezoelectric wafer. When the voltage frequency at both ends is equal to the resonance frequency of the chip, its output frequency is also equal to the maximum resonance frequency.

The Development and Advantages of Ultrasonic Scalpel
Although endoscopic surgery has such great advantages, at the same time, endoscopic surgery requires high anatomical accuracy, strong ability to effectively deal with blood vessels and high requirements for surgical instruments. The traditional electric knife (unipolar electric knife or bipolar electrocoagulation) can not solve the defects such as too wide heat conduction range (easy to cause side damage to important organs), unable to effectively deal with blood vessels, smoke and other defects which greatly affect the visual field and seriously restrict the expansion of the scope of endoscopic surgery. Until the birth of ultrasonic harmonic scalpel in 1996, endoscopic technology has been developed by leaps and bounds, which makes the minimally invasive surgical technology based on endoscopic surgery widely used in various surgical fields.
