Labor to observe


In less than a month, the World Conference on Artificial Intelligence 2022 will officially open. This reporter went to Shanghai artificial intelligence enterprises to understand how the industry guide is to break the barriers and bottlenecks of core technology, reflecting the power of AI.


  • Fill the market gap of interventional surgery robot


Shanghai Operation Robot Co., Ltd. is located in Kangqiao Advanced Manufacturing Technology Pioneer Area in Pudong New Area, home to many leading technology enterprises. Not long ago, Shanghai Operation Robot successfully completed the world's first human clinical study of robot-assisted peripheral vascular stent endovascular interventional surgery in the Department of Vascular Surgery, Shanghai Changhai Hospital. The success of the first clinical trial marks a historic leap in peripheral vascular interventional surgery, which has entered the era of robotic surgery.

On the simulated operating table, a robot equipped with a robotic arm demonstrated the whole process of stent placement on a life-size silicone blood vessel model. The staff only needs to use joysticks and various buttons on the side of the operating table to display the monitoring picture of the real-time video of the model. You can watch the video while using a joystick to remotely steer the guide wire through the catheter, leading the stent to the affected area for a smooth release.

According to field operators, traditional vascular interventional surgery, mainly operated by hand, is prone to jitters, displacement, overturning and other problems, resulting in vascular intervention is not accurate and safe; The standardized degree of surgery is low. It is also somewhat restrictive and usually requires years of training for surgeons to master. Therefore, the need for intravascular interventional surgery robot is very urgent. In theory, most surgeons can successfully operate the robotic system after a short training period, which enables standardized surgical precision and greatly reduces the learning difficulty of surgery.


The picture


However, it is challenging to come up with a robot at the same level as a clinician. To this end, Auburn Medical has built a versatile interventional robot through nearly a decade of forward-looking technology reserves. Previously, Auburn Medical has completed the world's first human clinical trials of robot-assisted aortic stent intervention, lower limb stent intervention, and coronary stent intervention.


  • Doctors' radiation doses were reduced by more than 90 percent


So, how useful is a vascular interventional robot in an operation? How can it help doctors and patients? The operating personnel, points out that compared with the traditional surgical treatment of traumatic big, high risk and difficult, complications, such as adverse effects, with the help of intracavitary interventional surgery robot, by digital technology to achieve precise positioning, can meet the needs of patients with individualized, improve the control precision, thus help doctors gain higher efficiency and more satisfied in the clinical curative effect.

At the same time, traditional vascular interventional surgery needs to be performed under X-ray radiation. Long-term exposure will lead to multi-system damage of the body. In order to prevent X-ray damage, the surgeon must wear lead clothing and other protective equipment for operation. In addition, long-term interventional surgery makes doctors prone to spinal disease, joint damage. With the robot, the distance limitation of surgery is firstly eliminated. With 5G enhanced, the remote operating system can help more patients receive treatment, while the surgeon does not have to be in the same room with the patient to perform such vascular surgery, avoiding exposure to radiation from X-ray imaging.

According to clinical data obtained by Shanghai Operation Robot so far, the exposure to radiation during traditional surgery would be more than 30 minutes, but with the help of the vascular intervention robot, this time can be reduced to a few minutes. This time is expected to be shorter as doctors become more proficient. It is expected to reduce radiation doses to doctors by more than 90 percent.


  • The goal: Robotic surgery


At the same time, the surgical robot can also use image navigation and mechanical assisted operation to accurately locate the lesions, optimize the delivery of instruments, shorten the time of instrument in place, and effectively improve the surgical accuracy and reduce surgical complications. In the post-pandemic era, remote operation can effectively reduce unnecessary exposure of doctors before patients and reduce the risk of infection. The appearance of surgical robot makes the intelligent and automatic vascular interventional surgery possible, and acts as the eye, hand and brain of doctors.

Liu Yikun, General Manager of Shanghai Operation Robot Co., Ltd., said in an interview that vascular interventional surgery robot will bring a generational breakthrough in the treatment of cardiovascular diseases, and its future development direction should be to achieve universal use in the whole department, complete surgical process coverage, and automatic surgery. And this, perhaps also is the domestic vascular interventional surgery robot overtaking opportunity.

He believes that the development goal of robots is to replace people in some dangerous or repetitive work, vascular interventional surgery robots have a natural advantage in the development of automatic. Although vascular interventional surgery requires higher precision operation, the treatment area faced by vascular interventional surgery robot with human blood vessels as access is limited. Environment & throughout; The degree of complexity is much lower, and combined with 3D image navigation, the lesions can be relatively simple to locate and dispose.

He likens it to driverless cars. “ Are in relatively fixed. Road & rsquo; Move forward, judge & LDquo; Road & throughout; To deal with the situation accordingly. The difference is that the road conditions faced by autonomous cars are much more complex, while the consequences of robotic surgical errors are much more serious.

Drawing on the auto autonomous driving classification,Shanghai Operation Robot has also developed a classification standard for the automation ability of vascular interventional surgery robots, ranging from 0 level of no automation to 5 level of full automation, a total of 6 levels. Liu Yikun introduced that Shanghai Operation Robot  has been aiming at the goal of fully automated vascular interventional surgery robot since its inception, and has set up a software department to research intelligent and automated technology, leading the industry.
