Research and development of in vitro physical vibration stone discharging machine, Zhengzhou Kangbaijia specializes in "crazy stone"

<b>(Reporter Ding Qian)</b> Even the strongest person may be knocked down by a small stone, which is the "crazy stone" buried in the body.

With the acceleration of the pace of life, the incidence of stone diseases has an upward trend, but the current clinical treatment methods are mostly in vitro shock wave lithotripsy, transureteral soft mirror lithotripsy, percutaneous nephrolitary lithotripsy, laparoscopic stone removal and other minimally invasive treatment after residual stone discharge, these methods are passive stone discharge, low stone discharge rate.

As an enterprise focusing on urological medical device related services, Zhengzhou Kangbaijia Technology Co., Ltd. (hereinafter referred to as Zhengzhou Kangbaijia) develops and produces in vitro physical vibration stone discharging machine, which greatly improves the net rate of stones and is of great significance to the development of the industry.

Research and development of in vitro physical vibration stone draining machine

From the production of drugs for the treatment of stones to the invention of the in vitro physical vibration stone discharging machine, Cao Fujian, chairman of Zhengzhou Kangbaijia, has been running to overcome stone disease.

"Stone disease is one of the three common diseases that plague humans, and most people choose drug treatment or passive stone removal treatment, but these two methods not only have a low stone discharge rate, but also the residual stones are easy to bring greater harm to patients." Before the development and invention of the in vitro physical vibration stone drainage machine, Cao Fujian was the regional marketing director of China of an imported pharmaceutical company, and has nearly 8 years of experience in academic exchanges with domestic urology. Based on the imperfection in the field of stone treatment, Cao Fujian resolutely resigned and led the scientific research team to attack the stone removal technology.

In fact, China is the world's second largest medical device market, especially in recent years, with the development of the economy, the demand for medical services for the people continues to increase, medical and health institutions and the number of patients increase year by year, the broad downstream market demand for the development of the medical device industry to provide favorable market conditions, the medical device industry market size further expanded.

Whether internal or external, society's need for higher technology to treat stone disease cannot be delayed.

"This technology had no precedent to refer to at that time, so it encountered many barriers and took many detours in the early stage of research and development." Cao Fujian recalled that in order to solve technical problems, the team went to many countries to investigate and invite experts from scientific research institutes to guide, and finally successfully developed an in vitro physical vibration stone discharging machine to overcome the public problem of physical stone discharge in vitro.

It is understood that the in vitro physical vibration stone discharging machine (EPVL) developed by Zhengzhou Kangbaijia solves the public problem that urinary stone crushing cannot be quickly discharged and drained after treatment. In 2020, the technology won the first prize of Henan Provincial Medical Science and Technology Progress Award and the first prize of Guangdong Province Science and Technology Progress Award.

Zhengzhou Kangbaijia has also been awarded the "Henan Provincial Urological Stone Surgery Robot Engineering Technology Research Center" by the Science and Technology Department of Henan Province, the "Zhengzhou Physical Vibration Stone Removal Medical Equipment Engineering Technology Research Center" by the Zhengzhou Municipal Science and Technology Bureau, and the "Zhengzhou Optoelectronic Medical Device Engineering Research Center" by the Zhengzhou Municipal Development and Reform Commission.

Cao Fujian introduced that the intelligent pressure control suction instrument uses optical fiber sensor technology to ensure the safety of surgery in real time for minimally invasive surgery, and to clean up residual stones in time to improve surgical efficiency. Also used in conjunction with this product are disposable endoscopic guide sheaths and disposable ureter guide sheaths.

Reduce the cost of treatment and let patients worry about the stone

In 2016, Professor Xu Changbao, a Chinese urologist and professor of the Second Affiliated Hospital of Zhengzhou University, made an academic exposition on physical vibrational stone drainage in vitro at the European Urological Congress, which attracted great attention from the international academic community.

Zhengzhou Kangbaijia research and development of the external physical vibration stone discharge machine will be passive stone discharge into active stone discharge, external physical vibration stone discharge machine greatly improve the stone discharge rate, from the original passive stone discharge rate of about 60%, increased to the active stone discharge rate of more than 97%; stone discharge cycle from the original passive stone discharge 90 days, shortened to 6 to 12 minutes.

Clinical application found that the device allows more patients with urinary stones to enjoy safe, effective and convenient diagnosis and treatment services, and the cost of treatment has also been reduced a lot, which is in line with the national medical reform goal of "allowing patients to see the disease, see the disease well, and see the disease".

The transcript of Zhengzhou Kangbaijia is the best proof of the outside world's affirmation of its technology.

It is reported that since its establishment in 2016, Zhengzhou Kangbaijia has achieved operating income of more than 5 million yuan in 2017; in 2018, 2019 and 2020, it has achieved operating income of 18.31 million yuan, 20.65 million yuan and 29.0346 million yuan respectively, and the revenue has achieved substantial growth.

In addition, Zhengzhou Kangbaijia has won the honors of "Advanced Enterprise for Innovative Development", "National Top Ten Units of Scientific and Technological Innovation", "National Excellent Demonstration Unit of Heavy Quality Brand", etc., and has 4 international and domestic invention patents, 14 utility model patents and 4 software copyrights.

"We will display our latest product , Friend , the In vitro physical vibration stone discharger — in 2021 National Mass Innovation and Entrepreneurship Week, to convey to the outside world that our Henan enterprises can also produce first-class high-end medical devices." For the next step, Cao Fujian said that he plans to launch a new technology product that can improve the current stone treatment plan within two years.
