B ultrasound, familiar and gentle to people, is an important means of clinical diagnosis of diseases. If a dangerous tumor can not only be detected by ultrasound, but also treated, it would be good. In the exhibition of "Wisdom Introduction innovation" of the Shanghai Academician (Expert) Workstation held by the Shanghai Association for Science and Technology, chen Yazhu, academician of the Chinese Academy of Engineering and professor of Shanghai Jiao Tong University, and Shanghai Shende Medical Device Technology Co., Ltd. jointly developed a new generation of domestic phase-controlled "magnetic wave knife" technology, which greatly increased the power of ultrasonic waves - accurately killing cancer cells in non-invasive and minimally invasive.
Because of the low cure rate and high mortality rate, tumors are one of the biggest killers of human health. At present, the treatment of malignant tumors mainly relies on traditional means such as surgery, radiotherapy and chemotherapy, and patients also suffer from hair loss, great decline in immunity, pain and other physical torture under great psychological pressure. The use of chemotherapy methods not only kills the cancer cells of the lesion, but also implicates the good cells in the human body; X-rays, various accelerators, proton knives, neutrons and other radiotherapy treatments also have damaging or negative effects.
Can you kill cancer cells in a gentler way? The high-intensity focused ultrasound therapy advocated by Academician Chen Yazhu in the early days is to focus the ultrasonic waves of the appropriate frequency emitted by the ultrasonic source on the target tissue in the human body through a certain focusing method, so that the local temperature of the target area rises rapidly, and then leads to necrosis, apoptosis or other thermal effects and cavitation effects of the cells in the target area, so as to achieve the purpose of treatment. "Compared with other treatment methods, focused ultrasound therapy is a non-invasive, low-side effect, safe and green new technology, with the characteristics of non-invasive, cohesive and controllable, and strong penetration." Academician Chen Yazhu once introduced it like this.
In September last year, the "Shende Medical Chen Yazhu Academician Workstation" was unveiled, and the "Academician (Expert) Workstation" of Shende Medical was officially established. In fact, this enterprise itself is under the guidance of Academician Chen Yazhu's concept of "green treatment" for tumors, and has embarked on the road of technological innovation step by step. ShenDe Medical Device was founded in 2013, the founder Shen Guofeng is a postdoctoral fellow of Chen Yazhu, an academician of the Chinese Academy of Engineering, and the phase-controlled magnetic wave knife has become the direction of joint efforts of enterprises and academicians.

The so-called "magnetic wave knife" is an instrument and equipment that gathers ultrasonic energy from outside the body in a "green, precise, personalized" way to tumors and other lesions, so that the tumor body temperature is rapidly increased to more than 65 ° C, so as to use high temperature to "burn" tumor tissue. Patients who undergo magnetic wave knife surgery do not leave any wounds, and the postoperative adverse reactions are small. Chen Yazhu's team completed the ex vivo experiment on more than ten sets of body membranes, hundreds of pounds of pork and more than ten cases of live rabbit experiments, the experimental conclusions show that the multi-array element phase-controlled PHIFU technology has the comprehensive advantages of single multi-focus "aiming", variable focal range, controllable focal length, ultrasound guidance, sound beam controllable, multi-mode treatment, which can achieve safe, non-traumatic and effective target ablation, "hundreds of shots" for cancer cells, and will not hurt "innocent" good cells.
With the matchmaking of the Shanghai Association for Science and Technology, the former mentor-apprentice transfer belt has gradually been upgraded to an academician (expert) workstation with "double excellence" social and economic benefits. The first-class scientific research treasures in the laboratory have become more products, and with the opportunity to face the market, the company has also developed the MRI-PHIFU series of ultrasound treatment products under the support of the academician expert scientific brain bank. "Our products have won a number of indicators in the same stage competition with similar foreign products, and it is expected that they will be able to obtain a medical device marketing license in the middle of next year." Standing in front of the exhibits of "a new generation of domestic phased controlled magnetic wave knife", Cui Lei, director of Shanghai Shende Medical Device Technology Co., Ltd., said proudly.
According to reports, compared with traditional surgery, chemotherapy, radiotherapy, proton heavy ion precision radiotherapy and other treatment methods, the new generation of domestic phase-controlled "magnetic wave knife" technology, with the advantages of non-invasive "non-invasive" treatment, will be an important supplement to traditional treatment methods. At present, ultrasound transcranial treatment of idiopathic tremor, epilepsy, Parkinson's, blood-brain barrier opening, brain tumors, and malignant tumors of hyperthermia and immune excitation and other products are also stepping up development.

As one of the carriers and service means for the Municipal Association for Science and Technology to deploy and build the "Science and Technology China" Shanghai action, the Shanghai Academician (Expert) Workstation, founded in 2009, has become a support platform for guiding high-end intellectual resources to gather in enterprises and promoting the deep integration of "production, education, research and application". In recent years, the construction of academician (expert) workstations has accelerated significantly, from building a station in a few years ago to 100 stations a year today. As of this month, the total number of stations built in Shanghai has reached 564, the number of academicians and experts working in the station has reached 3076, more than 2800 industry-university-research cooperation projects have been signed, more than 4500 key technical problems have been overcome, and more than 8300 patents have been obtained.
