"Haifudao Focus Ultrasound Tumor Treatment System JC300" is located behind the Chongqing unit exhibition logo and is presented in the form of an L-shaped screen and naked-eye 3D. This set of equipment comes from Chongqing Haifu Medical Technology Co., Ltd., a company in Liangjiang New District, .
"Haifudao" is China's first large-scale medical device with completely independent intellectual property rights. It emits ultrasonic in vitro to treat tumors in vivo non-invasively. His technology and achievements have won the second prize of the National Technical Invention Award, and have won 17 international invention patents and 36 Chinese invention patents, and have treated more than 200,000 benign and malignant solid tumors.
Professor Wang Zhibiao, Director of the State Key Laboratory of Ultrasonic Medical Engineering, Chongqing Medical University, is one of the inventors of "Haifudao".
In the 1980s, Wang Zhibiao had just participated in clinical work. A patient whose disease improved two years after surgery and whose uterus was removed from came to see Professor Wang Zhibiao and expressed his gratitude. However, Wang Zhibiao learned during the greeting that the patient was unable to have children after the uterus was removed due to illness. Wang Zhibiao felt very uncomfortable.
Can there be a way to kill tumors without harming other normal tissues and organs in the human body to avoid or reduce such tragedies?
After repeated thinking, Wang Zhibiao decided to take action. Since 1988, he has led his team to study and focus on ultrasound therapy techniques. After 9 years of research, it was the first in the world to break through the key core technologies of ultrasonic ablation surgery (FUAS) in the treatment of tumors in 1997. Two years later, China's first large-scale medical device with completely independent intellectual property rights, "Haifudao Focused Ultrasound Tumor Treatment System" was born and successfully applied to clinical practice. At present, the "Sea Stand Knife" equipment has been exported to nearly 30 countries and regions including the United Kingdom, Spain, Russia, and has retained the uterus for tens of thousands of women.
According to Wang Zhibiao, during the research and development process, his team needed to conduct a large number of ex vivo beef liver and live goat experiments to verify, and the experimental materials can be calculated on the order of "tons". The experimenters are sometimes very distressed. After the busy day of experiments, the bloody smell of beef liver lingers on their bodies and lingers. The residual smell of sheep always attracts strange eyes when everyone takes public transportation. But there is always someone to do things, let alone that's a meaningful thing. With the efforts of the team, technical difficulties have been broken again and again.
In the "Haifudao" treatment experiment, in order to ensure that the experimental organization is fresh enough, Wang Zhibiao's team conducted the experiment in the middle of the night for half a year, so it was called the "Night Owl Experimental Group". They constantly change the treatment head, change the software, change the tissue, change the tissue staining method. After repeated experiments, I finally achieved the ideal focus.
Review the road of innovation, Wang Zhibiao admitted that focusing ultrasound in biological tissue is a world-class problem. In the 1940s, American scholars first proposed the concept of using high-intensity focused ultrasound to implement non-invasive treatments for in vitro diseases. This tempting idea attracted developed countries such as the United States, Germany, Britain and Japan to explore for more than half a century, but because it was too complex, it was eventually stranded in the research stage. After thousands of experiments, he and his team finally came up with the safest and effective value, turning the dream of focusing ultrasound from the external body's external treatment of diseases into reality.
Focus on the research and development of ultrasonic ablation technology is a breakthrough from "none" to "existence", from 0 to 1. Now, Wang Zhibiao has led the team to the most difficult path, and he firmly believes that the future will be a "broad road".
Fuling shale gas underground three-dimensional development

Walked into the left side of the Chongqing unit and stood in front of the L-shaped naked-eye 3D screen. The first large shale gas field in my country to achieve commercial development - Fuling shale gas field , the first large-scale shale gas field in Fuling shale gas field , came into view. The display cabinet below the screen is placed in the miniature model of Fuling shale gas exploration and development. On the far right side of the model is the construction site of the double-drilling tower drilling "well factory". The drilling rig uses a grid-electric drilling rig, which can effectively reduce carbon emissions, energy consumption and noise pollution. Adjacent is the construction site of the "well factory" that represents the international advanced level. Compared with the traditional diesel-driven fracturing unit, the construction efficiency of the full electric fracturing is 70.9%, the carbon emissions of a single well are reduced by 92 tons, the area of the area is reduced by 23.07%, the energy consumption is reduced by 33.2% on average, and the noise is reduced by 46.3%. The intermediate area of
is a standardized gas collection station, which can initially dehydrate the produced shale gas and transport it to Baitao gas collection station. The far left of
is the Baitao Transportation Station, with a processing capacity of 16.5 million cubic meters per day. Shale gas is deeply dehydrated here. It is transported to more than 70 large and medium-sized cities, thousands of enterprises and more than 200 million residents through the Sichuan gas east-east transport pipeline to 6 provinces and 2 cities in the middle and lower reaches of the Yangtze River , more than 70 large and medium-sized cities, thousands of enterprises and more than 200 million residents to ensure industrial gas use and light up thousands of lights.
Ten years ago, Fuling shale gas broke through world-class problems and kicked off the commercial development of China shale gas ; ten years later, Fuling shale gas achieved the same excitement on the ground and underground on the basis of continuous technological efforts.
This year, Fuling shale gas has achieved many technological breakthroughs. At the beginning of the year, the Fenglai block of Fuling Shale Gas Field adopted the world's first "slimming well" technology, which reduced the cost of drilling a single well by an average of more than 3 million yuan. In the future, it will surely lead the domestic shale oil and gas drilling technology to achieve a revolutionary breakthrough; in March, the largest "well factory" in the Fuling Shale Gas Field in Sinopec Jianghan Oilfield was successful, setting a record for five domestic shale gas development, marking that the Fuling Shale Gas Field's full electric drive fracturing technology reached the world's leading level.
Fuling Shale Gas Field, as a national shale gas demonstration zone, is accelerating the improvement and establishment of a standardized management system, construction specifications and technical requirements that can be replicated and popularized, and drive great breakthroughs, development and prosperity of China's shale gas.
In addition to "Science and Innovation +", there is also "Green +". In the past two years, Fuling shale gas development has been put into use of negative pressure vibrating screens, forming a green production model of "reducing - reuse - recirculating". It is precisely because of the strong environmental protection measures that the production site of gas field forms an organic integration with the surrounding natural scenery. It can be said to be underground three-dimensional development and above-ground sightseeing.
Fuling shale gas innovatively implements three-dimensional development technology, changing the underground shale gas reservoir from the original single-layer development to layered development, forming a three-layer three-dimensional development technology that turns "one floor" into "three floors". This new technology enables the recovery rate of well groups or blocks in gas fields to reach up to 50%, which is a leading level worldwide. On the ground, the Fuling shale gas platform is standardized, and each construction platform is surrounded by green mountains. It is not only a petrochemical factory, but also a scene of Wuling , and has been included in the local industrial tourism system.
Now, people can go into the gas fields to visit "zero distance", or they can visit green gas fields and smart gas fields through the monthly "cloud opening" event.
