Harmonic Ultrasonic Scalpel, the Most Frequently Used Instrument in Surgery?

The ultrasonic energy device for surgical procedures was developed in the early 1990s.

The Cutting Principle of Ultrasonic Scalpel

During surgery, the surgical scalpel, light source, camera, and other medical instruments are inserted into the micro-hole at the same time. This avoids disturbances caused by the surgical scalpel itself and interferences with other instruments, which produce a "chopstick effect."

Introduction and Market Analysis of Ultrasonic Scalpel

The ultrasonic scalpel refers to the high-intensity ultrasound focused on the end of the knife through the amplitude bar. The strong vibration of the knife can crush soft tissues such as liver and organs. Clinical application of this method to remove soft tissue tumors in the human body can crush the tumor tissue debris at any time by flushing and suction, while the surrounding blood vessels and nerves are not easily damaged. Therefore, it is known as a bloodless surgical knife.

How to Determine the Operational Status of Ultrasonic Transducers?

Ultrasound transducer manufacturers often encounter situations where customers are unable to provide their actual usage and other detailed parameters, leading to incorrect selection of transducers. For ultrasound transducer manufacturers, they are relatively familiar with the design, implementation, and testing of ultrasound transducers, while for ultrasound equipment manufacturers, they are more familiar with the overall performance of the system and the environmental conditions of on-site applications.

Ultrasonic Scalpel in the Operating Room

Ultrasonic scalpel is a high-frequency electro-surgical device mainly used for cutting and vessel closure of biological tissues. It has the characteristics of less bleeding, less damage to surrounding tissues, and fast postoperative recovery. Its effect on human tissues is to cut and coagulate without causing side effects such as tissue dryness or burns. The knife head does not have electric current passing through the human body during operation, and it has a wide range of applications in the operating room and is also known as a bloodless surgical knife.

Ultrasonic Scalpel is One of the Most Commonly Used Energy Tools in Surgery Today

With the increasing development of science and technology, the scalpel is no longer a simple instrument cutting knife, in order to achieve the purpose of fast and accurate cutting and hemostasis. In recent decades, high-frequency electric knife and ultrasonic knife have come out one after another. Ultrasonic scalpel is considered to be a revolutionary product that affects the development of traditional surgery. It combines multiple functions such as cutting, hemostasis, separation and pulling into one body. It has good performances such as fast cutting, good hemostasis, less eschar and less damage. It has become a commonly used surgical tool in the hands of surgeons.

What Are the Influencing Factors of Different Structural Designs of Ultrasonic Transducers

Ultrasonic transducer, also called ultrasonic vibrator, is one of the most widely used energy conversion devices at present. As a device that can convert high-frequency electrical energy into mechanical energy, it converts the input electrical power into mechanical power and then transmits it out, and it consumes a lot of energy. With a small part of the power, ultrasonic transducers are widely used in the medical industry as well as in agriculture, national defense, biomedicine and scientific research.

Clinical Application and Development Trend of Ultrasonic Scalpel

Ultrasonic scalpels mainly include ultrasonic cataract emulsification, ultrasonic orthopedic surgery, ultrasonic surgical suction, ultrasonic hemostasis surgery, ultrasonic crushing of stones in vitro, high-intensity ultrasonic focusing surgery, etc. The development of hospitals and departments depends on the development and improvement of clinical medical technology, as well as the improvement of disease diagnosis and treatment methods. As an important part of the hospital's surgical system, the development of its surgical technology largely depends on the development and improvement of surgical technology. At present, the development trend of surgical techniques tends to be more and more minimally invasive, and laparoscopic surgery is one of the important components of minimally invasive surgery. The main advantages of laparoscopic surgery are: small surgical trauma, fast postoperative recovery, significantly shortened hospital stay; mild postoperative pain; the chance of surgical blood loss is reduced (90% of laparoscopic operations basically have no bleeding); the postoperative treatment is simple and the cost is reduced, and the patient also has the benefits of shortening the time of sick leave, returning to work earlier, and reducing the burden of family care.

Ultrasonic Transducer Applied to Electronic Sphygmomanometer

Ultrasonic transducer is one of the key components of medical ultrasonic equipment, and its characteristics directly affect or even limit the performance of the entire equipment. With the continuous development of piezoelectric materials and MEMS technology, small size, light weight, wide frequency band, high resolution, high frequency, and high sensitivity will be the main development direction of medical ultrasonic transducers in the future.
