If the robot is the crown of the manufacturing industry, then the medical robot is the jewel on the crown. Compared with traditional surgery, surgical robots have smaller wounds, faster recovery, and higher precision to perform more complex operations, which is undoubtedly a huge innovation in surgery. Surgical robots first appeared in 1985. The Los Angeles Hospital of the United States used the industrial robot PUMA560 for intracranial biopsy in neurosurgery. This is the first time that robots have participated in clinical operations.
Sagerui was established in 2013 by Du Zhijiang, a professor at Harbin Institute of Technology. From 2001 to 2022, Du Zhijiang successively served as lecturer, associate professor and professor of the School of Mechanical and Electrical Engineering of Harbin Institute of Technology; from 2008 to 2022, he served as the deputy director of the Institute of Robotics of Harbin Institute of Technology. After studying at Harbin Institute of Technology for four years, Du Zhijiang obtained the postgraduate recommendation qualification of the Institute of Robotics. His doctoral project was to make an automatic slag cleaning robot for a steel company in Shanghai. After graduating with a Ph.D. in 2001, Du Zhijiang continued to engage in the robotics business. He led the team to develop a coal mine detection robot and successfully realized industrial transformation. Since then, the development target has turned to medical robots.
Robotic-assisted laparoscopic extravesical ureteral reimplantation is a minimally invasive alternative to open surgery for the treatment of vesicorenal reflux or abnormalities such as ureterocele or megaureter in children and adults. At the same time, this technique has been adopted by a large number of surgeons, with a low incidence of complications and good long-term follow-up results. Prospective long-term analyzes of nerve-sparing extravesical robot-assisted laparoscopic ureteral reimplantation are needed. In our opinion, ureteral antireflux reimplantation by open surgery or robotic-assisted laparoscopy has some advantages, whether extravesical or intravesical. Angling of the ureters in different filling states of the bladder should be more easily avoided if the location of the neohistoria (entry point of the ureter into the bladder wall) and the orientation of the submucosal tunnel coincide with the anatomical course of the ureter. In addition, such a tunnel of sufficient caliber should allow simple ureteral catheterization or ureteroscopy. In ureteral reimplantation, it is worth mentioning that we try to avoid long-term placement of ureteral stents before surgery to prevent changes such as ureteral wall thickening from complicating surgical reconstruction.
Usually, open surgery requires blood transfusion, which brings risks such as infectious diseases, while robotic surgery causes very little bleeding. For ordinary open surgery, patients can be discharged from the hospital in 2 to 3 days, and resume normal activities after 6 weeks. However, after surgery with robots, patients can be discharged from the hospital in 1 day and can resume normal activities in 1 week.
In addition, taking prostatectomy as an example, if the operation is wrong and the nerves around the prostate are cut off, it can lead to impotence. Therefore, precise incision is very important. 25% to 60% of patients with ordinary prostatectomy suffer from impotence. However, the use of robots for surgery has a very low rate of postoperative impotence.
Cardiac surgery doctors use robots to perform operations, such as mitral valve repair and arterial surgery, without opening the ribs. The patient’s incision is only 3.7 to 5 cm, instead of the 20 to 25 cm incision in traditional surgery, which reduces the patient’s workload. Pain, and reduce bleeding and trauma.
Due to the unbalanced distribution of medical resources in my country, the phenomenon of cross-regional medical treatment in different places is very obvious. This not only increases the difficulty and cost of medical treatment, but also reduces the technical level of grassroots medical institutions due to unreasonable flow directions, and the medical advantages of large hospitals cannot be obtained. Utilization has virtually wasted medical resources. Especially for common diseases such as fractures, remote diagnosis and remote surgery can make full use of reasonable medical resources to solve the problem of difficult and expensive treatment for patients. In response to this, my country is building a demonstration scenario for the application of 5G remote orthopedic surgery robots to explore an economical, effective and safe remote diagnosis and treatment model for orthopedic surgery robots.
In recent years, the global medical robot market has grown rapidly, among which surgical robots have the largest scale and rehabilitation robots have the fastest growth rate. Exoskeleton robots in subdivided fields will usher in explosive growth. High growth rate. In 2021, the global medical robot market is expected to reach 20.7 billion US dollars.
Medical robots do not need to be large-scale robots that are time-consuming and expensive to develop. Most scenarios require small, sophisticated, intelligent robots and doctors to cooperate to complete operations. Making the robot smaller is also conducive to earlier detection of lesions and diagnosis and treatment.
