More than 60
The "Miaoshou" robot has the characteristics of miniaturization and integration, optimized layout, and exquisite structure. It has broken through the decoupling design of multi-degree-of-freedom wire transmission of minimally invasive surgical machinery. Three key technical problems such as the construction of structural control models have solved the complete set of technical problems for robots.
At present, the robot system has applied for more than 60 invention patents, of which more than 40 have been authorized.
Recently, Professor Niu Haitao, director of the Department of Urology, Qingdao University Affiliated Hospital, sat firmly on the console, operating the main controller with both hands, using the foot pedal to control the instrument and a 3D high-definition endoscope, and remotely controlling Guizhou nearly 3000 kilometers away through the 5G network. The "Wonder" operating end in the operating room of the People's Hospital of Xixiu District, Anshun City, Anshun City, performs robot-assisted laparoscopic radical bladder resection for patients.
As the chief surgeon, Niu Haitao’s challenge is: whether the “mighty hand” surgical robot he relies on can synchronously and accurately “copy and paste” his movements, and finally complete the precise resection of the lesion step by step and ensure that the operation is performed. The patient had no obvious bleeding and peripheral organ damage and other complications.
In the end, the operation was a success.
In addition to the superb medical skills of the chief surgeon, the accuracy of the surgical robot is also an indispensable factor.
The reporter learned that under the authorization of the National Medical Products Administration, 168 cases of such a combination surgery of "main surgeon + domestic robot" have been implemented in China.
The operation is more precise, allowing the doctor to complete the operation while sitting
This robot called "Miaoshou" is called a new generation of domestically developed surgical robots.
What kind of surgical robot is this?
In late September, a reporter from Science and Technology Daily drove 600 kilometers to Shandong Weigao Surgical Robot Co., Ltd. (hereinafter referred to as Weigao Robot) located in Weihai Lingang Economic and Technological Development Zone, Shandong Province, and found the answer here.
In the workshop of Weigao Robotics, brand-new surgical robots are lined up in a row and extended out. There are 40 or 50 visually inspected.
Wang Bingqiang, head of Weigao Robotics, told the reporter of Science and Technology Daily: "We have applied for more than 60 invention patents for this system, of which more than 40 have been authorized."
The reporter learned that behind these more than 60 invention patents, the robot has broken through numerous obstacles and achieved a series of major technological breakthroughs in safety technology, product prototype system integration technology, and three-dimensional display technology.
Compared with manual operation and traditional endoscopic minimally invasive surgery, surgical robots make surgical operations more precise and accurate.
Professor Wang Shuxin of Tianjin University, who cooperates with Weigao Robotics in production, education and research, said in an interview with the media that the robotic arm of the "Miaoshou" robot can rotate and swing 360 degrees freely, rotating and twisting in all directions without pressure, and can filter out operations. The doctor's hands are shaking, and he can sew and tie knots dexterously.
At the same time, the "stereoscopic image display window" on the system can use a viewing lens to magnify the surgical field of view by several times.
Through this window, the doctor sees a three-dimensional high-definition image, the field of vision is clearer, and the quality of the operation is significantly improved.
In addition, with the help of "smart hands", doctors can complete operations while sitting, making it easier to perform long-term complex operations.
"The development of surgical robots is not to replace doctors, but to extend the surgical capabilities of doctors." Professor Wang Shuxin said, "Like a minimally invasive surgery like laparoscopy, the screen that the human eye sees is flat and the image magnification is not large, but if With the surgical robot system, the image can be magnified more than 10 times, and the robot's mechanical arm can enter the abdominal cavity, and a larger, more three-dimensional and intuitive image can be seen on the screen."
Break the foreign monopoly and solve the complete set of technical problems
Public information shows: On April 4, 2014, the Third Xiangya Hospital of Central South University took the lead in China to carry out domestically-made surgical robot gastric perforation repair and appendectomy.
The surgical robot integrates a number of modern high-tech methods.
In the field of minimally invasive surgery in the world, it is a well-deserved revolutionary surgical tool.
With it, surgeons can operate machines away from the operating table to perform operations, which subverts the traditional concept of surgery.
Surgery has undergone a transformation from traditional open surgery to laparoscopic surgery, and today's surgical robot is its "third revolution."
However, the market demand for surgical robots is huge and the threshold is extremely high. At present, the only mature product in the world comes from the United States. Da Vinci surgical robots are based on the robotic surgery technology developed by the Stanford Research Institute.
According to incomplete statistics, since the 1990s, the United States has produced more than 5,000 Da Vinci surgical robots. Among them, my country has introduced more than 200 for general surgery, urology, cardiology, thoracic surgery, and gynecology. Difficult surgery in many fields.
Why not introduce such a good product?
Industry insiders told reporters that the Da Vinci surgical robot is very "burning money", with an import price of more than 20 million yuan, and later consumables need to be imported from the United States, and the price is also very high.
Nowadays, the domestically produced "Miaoshou" robot has changed all of this.
According to Wang Bingqiang, the "Miaoshou" robot co-operated by Tianjin University and Weigao Robotics is a brand-new endoscopic-assisted surgical robot with independent intellectual property rights.
Its main hardware, software, materials and system design are all independently developed by my country.
Compared with imported surgical robots, the "Miaoshou" has the characteristics of miniaturization and integration, optimized layout, and exquisite structure. It has broken through the decoupling design of multi-degree-of-freedom wire transmission of minimally invasive surgical machinery, and the reconfigurable layout of the operator Three key technical issues, such as principle and implementation, and the construction of system heterogeneous and isomorphic control models, have solved the complete set of technical problems of robots.
What's more commendable is that its application broke the global monopoly of foreign surgical robot technology and greatly reduced the medical expenses of domestic patients.
Overcoming the obstacles to landing, the "smart hand" is about to enter the market
"From lens film manufacturing, to assembly and final imaging software, we have broken through the minimally invasive surgical robot system integration technology, breaking the absolute monopoly of foreign robotic systems in this field. Chinese minimally invasive surgical robots with complete independent intellectual property rights , Realized the independent innovation of high-end medical equipment." Wang Shuxin said.
Many people still remember that in the "Challenge Impossible" program broadcast by CCTV last year, the above-mentioned domestic robot cooperated with the chief surgeon 700 kilometers away to challenge the remote stitching of egg membranes.
The inner membrane of the raw egg shell is about 0.07 mm thick, thin and brittle. This domestic robot can actually "fly needle routing" on it. After the stitching is completed, the egg liquid does not flow out, which shows its skill.
It is understood that domestic medical robots started late and are still in the early stages of development, that is, the investment stage of technology and capital.
However, in view of the fact that various medical robots will become the mainstream of surgical operations in the future, it has attracted many entrants.
The products of each team have their own characteristics and compete with each other.
"The field of medical robots is characterized by high thresholds and barriers, especially in the field of surgical robots, which is a comprehensive field involving a number of high-precision technologies." Lu Zhangyuan, director of the Advanced Robotics Industry Research Institute, has publicly pointed out the difficulties faced by medical robots. , "On the one hand, more domestic medical robotics technologies come from universities and research institutes. From technology to products, to mature applications, it takes a long period of verification, iteration, and improvement. At the same time, multiple industry certifications are required. In order to achieve the first step in landing applications; on the other hand, the public (or hospitals) do not have enough awareness of medical robots, and the domestic medical system has not yet included medical robots in the scope of medical insurance on a large scale. This also affects medical care to a certain extent. The commercialization process of robots."
The reporter learned that after overcoming various obstacles to landing, the "Wonderful" robot will enter the market by the end of this year.
