World Hepatitis Day | How to care for the "little heart"?

July 28, 2023 is the 13th "World Hepatitis Day", in China, liver disease has been a high incidence and common disease among Chinese residents. There are five main strains of hepatitis virus, called A, B, C, D and E. Hepatitis B and C cause chronic diseases for hundreds of millions of people and are the most common cause of death from cirrhosis, cancer and viral hepatitis.

According to statistics, there are about 10 million people infected with hepatitis C virus in China, and the rate of 200,000 people every year continues to increase; About 70 million people are infected with hepatitis B, 28 million of whom have chronic hepatitis B.

The liver is a very complex place to complete the transformation of some substances in the human body. The lesions often start from hepatitis, and the hepatitis virus replicates and multiplies in the liver, leading to inflammation and necrosis of liver cells, causing sustained damage to the liver. With further changes in the interior of the diseased cells leading to cancer, hepatitis gradually develops (deteriorates) to cirrhosis, and then from cirrhosis to liver cancer, which is called the "trilogy" of liver disease death.

The National Health Commission commissioned the organization of multidisciplinary experts in the field of liver cancer across the country, combined with the latest practice of clinical diagnosis, treatment and research of liver cancer, to revise and update the 2022 edition of Primary Liver Cancer Diagnosis and Treatment Guidelines, pointing out that surgical treatment of liver cancer is an important means for liver cancer patients to achieve long-term survival, and the main surgical methods include hepatectomy and liver transplantation.

During hepatectomy, the technique of blood flow control in and out of the liver, liver dissection and hemostasis are highly required. At the same time, because the liver is the largest internal organ in the human body, it bears the important functions of metabolism and life maintenance, so it is also necessary to protect the liver itself during surgery. Ultrasonic knife is widely used in this operation because it can also close blood vessels in time and has little thermal damage.

To break the monopoly of international ultrasound technology, domestic alternatives are preferred

As a clinical oriented medical minimally invasive company that always pays attention to the needs of patients, the length specifications of the ultrasonic cutter head of Hende range from 14cm, 22cm, 36cm to 45cm, from open surgery to laparoscopic surgery, from superficial thyroid surgery to deeper weight loss surgery.

The 22cm ultrasonic knife is mainly used in open surgery, and the 36cm ultrasonic knife is mainly used in laparoscopic surgery. Both models meet liver surgery requirements.

In addition, the advantages of high-speed frequency tracking technology and intelligent HAT core algorithm carried by Hende ultrasonic host can achieve high-speed frequency tracking of about 100,000 times per second, and frequency adjustment of 20,000 times, accurate output energy, and higher cutting efficiency. The optimization of the tool head tissue adaptive algorithm greatly reduces the thermal damage, and the lateral thermal damage is <1mm. At the same time, the host has a complete self-test system to reduce the preparation time before surgery.

At present, Hende ultrasonic knife is widely used in liver resection at home and abroad, and has covered more than 100 first-class hospitals in China.

According to the World Health Organization survey data, more than 1 million people die of hepatitis every year, there is a new chronic infection every 10 seconds, China is the world's largest hepatitis C patients. Hepatitis is affecting people's work and quality of life. How to improve the scientific cognition of hepatitis, daily maintenance, correct treatment, is becoming more and more people's required courses.

Hande will continue to enhance its technological innovation capabilities, build technical barriers, and launch more high-performance, high-quality, easy-to-use and affordable surgical instruments for patients and doctors, helping the high-quality development of domestic medical devices and bringing good news to patients.
