Electrosurgical generators are the devices that use high-frequency (HF) electrical currents to cut or coagulate tissue during surgery, known as electrosurgery. It consists of an electrosurgical generator that transforms electrical energy into HF current. It is operated using a specific control.
Electrosurgery is the application of a high-frequency (radio frequency) alternating polarity, electrical current to biological tissue as a means to cut, coagulate, desiccate, or fulgurate tissue. Its benefits include the ability to make precise cuts with limited blood loss. Electrosurgical devices are frequently used during surgical operations helping to prevent blood loss in hospital operating rooms or in outpatient procedures.
The cautery method is the basic principle of high-frequency electrosurgical treatment. Its application to disease treatment can be traced back to prehistoric times. People use heated stones to stop bleeding. In the early 1920s, surgeons used the method of cauterization and current to treat patients, and now the cautery method has become one of the most commonly applied techniques. Plant physiologist William T. Bovie is considered the father of high-frequency electrosurgical surgery [1].
In the 19th century, medical treatment gradually realized electronic. In 1897, Franz Nagelschmidt wrote an article on "Electrothermal Therapy" to illustrate the thermal effect discovered by d'A rsonval six years ago.
In 1900, the Parisian physician Joseph Rivered made an innovative discovery in his work. When he treated an insomnia patient with an electric current generated by a generator similar to Nagelschmidt, the spark arc between the electrodes solidified the patient’s skin, and he finally used this This arc current treated a patient with a cancerous ulcer on the hand. This is the first recorded case of a surgical operation using high-frequency current [2]. In the following ten years, people generally used electric current to treat skin damage, oral and bladder hemangioma, hemorrhoid coagulation and other diseases [3].
In 1910, Clark designed and produced a new device that can generate up to 3A of current. By increasing the current and reducing the voltage, it generates a spark with greater heat and shorter time, which can penetrate deeper layers of the human body tissues [4].
In 1914, he used the "drying method" to describe the effects of tissue damage and carbonization due to dehydration. Clark became the first American to routinely use this method to remove malignant hyperplasia of the skin, head, neck, breast and cervix. Since then, he pioneered the American high-frequency electrosurgical technology and promoted the rapid development of this type of technology [5].
After cutting the tissue with the high-frequency electrosurgical knife, the cut wound is neat and without blood oozing, but it can cause local tissue blood supply obstacles, tissue cell destruction, partial tissue carbonization and fat liquefaction. At present, high-frequency electrosurgical units are widely used in departments of gynecology, stomatology, general surgery, etc., and can be used in various traditional surgical operations, including: splenectomy, thyroidectomy, liver resection, lung resection, hemorrhoid resection, gastrectomy, Nephrectomy, etc.
EB05 electrosurgical generator combines versatility and safety, for all general electrosurgical procedures such as cutting and coagulation in clinics, offices and emergency rooms.
Application
EB05 well combines safety and effectiveness for a broad range of electrosurgical needs, such as General surgery, Cardiology, ENT surgery, Gastroenterology, Gynaecology, Laparoscopy, Neuro surgery, Plastic surgery, Thoracic surgery and Urology.
EB03 electrosurgical generator is a versatile electrosurgical unit for all around surgical procedures through all types of tissue. It has integrated seven power output, tissue responding and automatic solid or split return electrode recognition functions, with which surgeons can perform highly precise and safe operations.
Application
EB03 is applicable in various surgeries such as general surgery, dermatology, plastic surgery, endoscopy, vascular surgery, heart/thoracic surgery, minimally invasive surgery, neurosurgery and ophthalmology.
