Recently, under the leadership of Academician Han Yaling, the Cardiology Department of the General Hospital of the Northern Theater Command of the Chinese People's Liberation Army, the electrophysiology expert team led by Professor Wang Zulu successfully performed ICE-guided cardiac interventional therapy for two atrial fibrillation patients using the intracardiac ultrasound imaging system ("ICE system") independently developed by Shenzhen Saihe Medical Technology Co., Ltd. (hereinafter referred to as "Saihe Medical"). This is the world's first batch of clinical applications after the launch of China's original ICE system, and also the first two clinical applications in the whole army.
Saihe Medical's independently developed intracardiac ultrasound imaging system was officially approved for marketing by the National Medical Products Administration (NMPA) in July 2024, becoming the first domestic ICE system (catheter + host) approved after entering the innovation green channel in China.
System Capabilities
The ICE system has a greater detection depth, which is not only suitable for all conventional cardiac interventional surgeries, but also can optimize the operation of left atrial appendage occlusion under intracardiac ultrasound guidance, improve surgical efficiency and reduce complications. Its principle is that the micro phased array probe at the tip of the ICE catheter continuously emits ultrasonic signals and receives echoes to perform real-time, high-quality imaging of the intracardiac anatomical structure, which is an important auxiliary means in cardiac interventional therapy.
System Components
- The ultrasonic diagnostic instrument consists of an ultrasonic host, a connector and a power adapter.
- The disposable intracardiac ultrasound imaging catheter is composed of a catheter tip, a bendable tube, an operating handle and a tail connector.
- It uses the inverse piezoelectric effect to convert the pulsed electrical signal output by the ultrasonic diagnostic instrument into ultrasonic waves, which are emitted to the intracardiac tissues, and receives the echo signals, which are transmitted to the ultrasonic diagnostic instrument and converted into digital image signals to be displayed on the monitor.
Technical Innovation
As a key component for rotational signal transmission in the ICE system, the micro-sized, long-life, high-speed slip ring directly affects the stability and reliability of the entire system. Traditional slip ring technologies often have problems such as limited rotational speed, large heat generation and short service life, which are difficult to meet the ICE system's requirements for high speed, high precision and long life.
Saihe Medical's intracardiac ultrasound imaging system adopts the 60MHz operating frequency high-speed, cooling-free, long-life slip ring "SP024002-004-P1-A" exclusively developed by Hantang. This micro-sized, high-speed, long-life slip ring has a maximum rotational speed of 6000 rpm and a service life of 80 million revolutions, with stable performance. It has broken through a number of technical bottlenecks and achieved excellent performance in high rotational speed, low noise, micro size and long life. As one of our company's key technologies, this micro-sized, high-speed, long-life slip ring has been successfully applied in large quantities to a domestic medical device, and has been fully verified and recognized by users.
Future Outlook
In the future, with the continuous progress and innovation of medical technology, it is believed that the independent research and development capabilities of domestic enterprises in the field of high-end medical devices will be further enhanced. Hantang also looks forward to the continuous emergence of more innovative technologies. As a domestic enterprise with the most comprehensive research on high-speed, micro-sized, long-life electrical contact basic technologies, SPR-ing will continue to keep the door open for technical services and contribute more Chinese wisdom and strength to the development of the global medical and health industry.
