China News Service, Shanghai, September 15 (Chen Jing, Wang Genhua) With the development of medical technology, the "doctor + robot" model is now breaking through the operational limitations in many traditional surgical procedures, and minimally invasive surgical procedures have entered a new era.
reporter visited the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital) on the 15th. In the operating room, a difficult "radical prostate surgery + pelvic lymph node dissection" is underway. Above the operating table, a big guy with three heads and four arms skillfully retracted and turned his "head" and "arm" to perform surgery on the patient. 3 meters away from the operating table, Ren Shancheng, director of urology, was "hardened" the fourth generation of Da Vinci surgical robot XI system through the operating platform. With the support of naked-eye 3D and 450-degree arm rotation... This extremely challenging operation took only 90 minutes.
According to Professor Ren Shancheng, compared with open surgery or traditional laparoscopic surgery, the unique naked-eye 3D effect of the fourth generation of Da Vinci surgical robot can enlarge the surgical site by more than 10 times, three-dimensional, three-dimensional high-definition field of view, enlarged images and automatic filtering and defibrillation function, allowing doctors to see clearly during the operation, operate more stably, naturally and accurately, and the surgical process is safer.
It is understood that the urology team of Shanghai Changzheng Hospital is one of the earliest teams in China to carry out robotic surgery and have the largest number of cases completed. Since the hospital introduced the first "Da Vinci" robotic surgery system in 2016, the number of urology robotic surgery has increased rapidly. So far, Professor Ren Shancheng, director of the Robotics Center, has completed more than 1,800 robotic surgeries for various urinary system tumors.
This expert told reporters that the imaging system of the fourth generation of Da Vinci surgical robot has multi-angle automatic switching function, and its bending and rotation angle are far beyond the limit of the human hand. It is more flexible, and can complete surgical actions that are difficult for human hand to complete, and can handle tumors in "dead angles" easily. Ren Shancheng said that the fourth-generation Da Vinci surgical robotic arm is thinner than the previous generation model, the robotic arm is longer, and the range of movement is larger, and it can also complete single-hole laparoscopic surgery.
74-year-old Mr. Wang, who underwent surgery this time, underwent radical left kidney resection more than 10 years ago due to renal cancer , and underwent intracranial hematoma removal for cerebral hemorrhage of cerebral hemorrhage of six months ago. In a recent routine review, he was found to have prostate cancer . After fully evaluating the patient's condition, Ren Shancheng judged that using the fourth generation of Da Vinci robots, the patient still has a chance of surgery.
During the operation, the doctor first opened a "small hole" about 2 cm in the lower part of Mr. Wang's lower abdomen, placed it into a special channel for robots, and inserted the robotic arm into the abdominal cavity. Director Ren Shancheng remotely controlled robot arm in front of the console outside the surgical area to perform surgical operations on the patient. Although the patient's middle lobe of the prostate clearly protrudes into the bladder and is locally severely adhesive, under the operation of experts, the robot's four rotatable wrist-like robot arms cooperate with each other, and the lesion prostate is flexibly and accurately separated, removed, sutured, and reconstructed in a narrow surgical area. The entire operation process was very smooth, the amount of bleeding in the surgical area was only about 30ml, and the patient's indicators were stable. Director Ren Shancheng, who walked off the operating table, admitted in an interview: "The fourth generation of Da Vinci surgical robot XI system is put into use, which can help doctors solve many limitations facing surgical treatment." Ren Shancheng said that after the prostate is removed, the doctor needs to perform suture and reconstruction of the bladder and urethra, but these two organs are deep in the pelvic cavity. In the earliest surgical period, the above-mentioned operations were almost sutured by the doctor's "feel"; in the laparoscopic era, although the field of surgery was greatly expanded, the operation still had limitations - laparoscopic instruments cannot turn, and suturing deep blood vessels and other sutures are still not 100% accurate, so the incidence of postoperative complications such as urinary incontinence and urethral stenosis is relatively high. With the assistance of the fourth generation of Da Vinci surgical robot XI system, similar problems are solved. "For patients, they can get better diagnosis and treatment," the expert said.(End)
