E-WellTech: Intelligent Pressure Control, World's First — Medical Endoscopic Pressure-Control Imaging System [Artery Select New Product Review Episode 49]

Urinary calculi are a common condition in urology, ranking first among hospitalized patients. In recent years, the incidence of urinary calculi in China has shown an upward trend, making it one of the three high-prevalence regions worldwide. The prevalence of urinary tract stones ranges from 1.5% to 18%, with a 5- to 10-year recurrence rate exceeding 50%.

After years of development, YiWeiTe has established a product portfolio centered on intelligent pressure control technology, grounded in intraluminal fluid pressure regulation, and anchored by devices for the treatment of urinary stones.

On Monday, March 25, at 19:30, the 49th session of VCBeat Select New Product Showcase will feature Song Leming, Chairman of YiWeiTe, who will deliver a product presentation.

Building upon the intelligent pressure-controlled lithotripsy, irrigation, and suction system for intraluminal urinary procedures, this upgraded system integrates an imaging module. It is another innovative medical device that combines endoscopic imaging, fluid irrigation, negative-pressure suction, and fluid pressure monitoring and control into a single unit. Upon market launch, it is poised to once again lead the field of urinary stone treatment.

More Refined Safety Upgrades:Visible waste fluid capacity, secure snap-fit connection, active waste replacement alerts, irrigation and suction flow comparison, prevention of waste fluid ingress into the main unit. Precisely address issues in intraoperative manual procedures that are difficult to judge and prone to being overlooked, ensuring safety to enhance surgical efficiency.

Innovative Dual-Screen Design:Integrated display of endoscopic images, pressure, and flow provides physicians with an optimal visual experience, while the rear screen offers nurses a user-friendly interface for convenient operation.

Disposable Ureteroscope Catheter:Straight-line instrument channel for smoother access; flow adjustment and on/off control allow physicians to set parameters instantly, freeing up nurses and improving efficiency.

Expand Connectivity, Unlock More Possibilities:Ethernet port, USB, and expandable HDMI to meet diverse needs.

YiWeiTe | Chairman

For over a decade, I have focused on research into minimally invasive treatments for urinary calculi, leading multiple major projects funded by provincial and municipal science and technology departments, with total research funding exceeding RMB 4 million. I have published more than 50 papers as first or corresponding author, including over 20 indexed in SCI journals. My independently developed technologies have been presented four times at the American Urological Association (AUA) Annual Meeting. I hold six national patents, including a national invention patent for the “Medical Irrigation and Suction Platform.” I independently researched and developed two medical devices: the “Micro-access Percutaneous Nephrolithotomy Suction Stone Clearance System” and the “Intelligent Pressure-Controlled Endourological Lithotripsy Irrigation and Suction Stone Clearance System.” I pioneered three techniques internationally: “Micro-access Percutaneous Nephrolithotomy with Suction Stone Extraction,” “Intelligent Pressure-Controlled Transnatural Orifice Suction Stone Extraction,” and “Intelligent Pressure-Controlled Percutaneous Nephrolithotomy with Suction Stone Extraction.” The research achievement titled “Clinical Study on the Treatment of Staghorn Renal Calculi Using the Micro-access Percutaneous Nephrolithotomy Suction Stone Clearance System” received the Second Prize for Scientific and Technological Progress from the Jiangxi Provincial People’s Government in 2014. The projects I led to completion, namely the “Medical Irrigation and Suction Platform” and the “Research and Development of Intelligent Intrarenal Pressure-Controlled Flexible Ureteroscopic Suction Stone Extraction Technology and Related Instruments,” were recognized as “Scientific and Technological Achievements” by the Jiangxi Provincial Department of Science and Technology (with me as the primary contributor).

The innovatively developed “Intelligent Pressure-Controlled Lithotripsy Irrigation and Aspiration System for Endourological Stone Clearance” is the first product in Jiangxi Province and the only one in Ganzhou City to be granted entry into the “Special Approval Procedure for Innovative Medical Devices” by the National Medical Products Administration. For consecutive years, it has been invited to deliver special reports and live surgical demonstrations at the Stone Disease Group sessions of the Chinese Urological Association (CUA) Annual Conference. The pioneering technique, “Flexible Ureteroscopic Lithotripsy with Intelligent Intrarenal Pressure Monitoring and Aspiration,” was featured in a surgical video published in 2015 in the Journal of Endourology, which earned the distinction of being the most-viewed article globally in that journal for 2015. In 2023, the Chinese Alliance for Urinary Stones officially established the Training Center for Intelligent Pressure-Controlled Stone Removal Technology under its auspices. To date, the center has conducted 18 training programs, directly training nearly 300 urology specialists from across China, with over 15,000 cumulative online viewers tuning in to watch live surgical demonstrations.

Jiangxi YiWeiTe Technology Co., Ltd. was jointly founded by clinical experts in hospital urology, professors of materials science from universities, and mechatronics specialists. After years of development, the company has become an innovative high-tech medical enterprise characterized by multidisciplinary integration, specializing in the research, development, and production of medical devices, with a focus on translating new technological achievements in the field of intracorporeal fluid pressure control. Guided by the R&D philosophy of making surgeries safer and more efficient, the company has established a product portfolio centered on intelligent pressure control technology, based on intracorporeal fluid pressure regulation, and anchored by instruments for the treatment of urinary calculi. These products are widely applicable in areas such as the treatment of urinary and hepatobiliary stones, hysteroscopic surgery, and other fields. In combination with robotic surgical systems, the company is poised to become a global leader in consumables for liquid-medium endoscopic equipment.

“Artery Select New Product Launch” is a live-streaming program under the “Artery Select” brand, dedicated to supporting medical enterprises in launching innovative products. The program’s mission is: to empower every milestone launch of innovative medical products.
