On March 8, 2022, the team of Professor Zhao Ren from Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine “controlled” the Shurui single-port surgical robot with complete independent intellectual property rights, and successfully completed the first radical operation for sigmoid colon cancer. The remote operation time of this operation was 86 minutes, and the operation team of Ruijin Hospital gave a high evaluation of the operation performance of the single-hole robot, with smooth operation, precise movements and excellent overall performance.

Sigmoid cancer is a highly malignant tumor. The highest incidence is in the age group of 60 to 70 years old, and it is not easy to detect in the early stage. The main treatment is surgical resection, and radical resection of sigmoid colon cancer is used to control the deterioration and development of the disease.
The operation was performed by Professor Zhao Ren, vice president of Ruijin Hospital, who performed radical resection of sigmoid colon cancer. The patient was a 62-year-old male. After detailed discussion and precise planning by the surgical executive team, it was determined that a 3.5cm incision was made in the rectus abdominis on the right side of the umbilicus, and a special multi-channel sheath was used to place the 3D endoscope with a sharp single-hole surgical robot and three serpentine surgeries. The surgeon performs the operation under teleoperation by using tissue grasping forceps, bipolar grasping forceps and monopolar curved scissors. First, the abdominal cavity was explored, the small intestine was opened to locate the sigmoid colon, and then the sigmoid colon was pulled and exposed along the middle approach, the root of the sigmoid mesentery was opened, the blood vessels were freed, the inferior mesenteric artery was cut off after double ligation, and the mesentery was separated until the distal colon was cut and closed. Finally, the intestines were freed and naked, and the anastomosis was cut off. The entire operation lasted 172 minutes, of which the teleoperation time of the Zhurui surgical robot was 86 minutes, and the patient’s blood loss was only 10ml, and he is recovering well.

The Shurui single-port surgical robot that participated in this operation is a product independently developed by Shurui Company in conjunction with Shanghai Jiaotong University, Ruijin Hospital and other universities and hospitals. It is supported by the Ministry of Science and Technology’s “National Key Research and Development Program”, and has a full chain of key technologies and all-round With independent intellectual property rights, its performance is comparable to the world’s top surgical robots in terms of precision and smooth operation. Surui single-port endoscopic surgical robot contains a total of 68 high-precision servo motors, which are used for preoperative auxiliary positioning, intraoperative operation and master-slave control. The dual-loop independent control hardware topology for full-state safety monitoring is creatively designed. The full-link master-slave operation delay is less than 50 milliseconds, and 1,000 sub-millimeter surgeries can be accurately controlled per second.

With the successful treatment of the first case of sigmoid colon cancer radical resection, it marks that the single-port surgical robot has opened up a new surgical application field after urology. Looking at the global endoscopic robot market, only the Da Vinci SP single-port surgical robot has been approved for listing, but due to its advanced industry and technology, export to China is currently restricted. This clinical application innovation of Shurui single-hole surgical robot will surely contribute to the realization of “not yet imported, can be replaced” for Shurui robots, and will also add luster to the establishment of “a new benchmark for China’s intelligent manufacturing in the new era” and lead the industry.” A new era of single-port surgical technology “opens the border and expands, and finally contributes to the sinking of high-end medical resources and the universal benefit of doctors and patients!
