An hour before the operation started, another doctor called Dr. Ren Shancheng and said, "The patient said that he would like to say a few more words to you before anesthesia." It can be felt that the patient is still a little worried.
This surgery is special even if it is said to be special, but it is not special even if it is not special.
Especially because, in addition to Ren Shancheng, deputy chief physician of the Urology Department of Shanghai Changhai Hospital, who performed the surgery, there was also a guy who was "not a human" - the Da Vinci surgical robot.
No, especially because the hospital uses da Vinci in two or three surgeries every day. Dr. Ren is already very proficient in this, having obtained the robot four years ago. Qualifications for surgery.
How did Leonardo da Vinci perform the surgery?
Because he was already used to "partnering" with Leonardo da Vinci, Dr. Ren easily introduced the function of each part while changing into surgical clothes.
The full name of the Da Vinci surgical robot is "Da Vinci Robot-Assisted Surgical System". It does not look like a "person", but consists of a surgeon's console, four robotic arm systems and The high-definition imaging system consists of three parts.
Da Vinci's four robotic arms are like spider legs, which can rotate and bend. The "wrist" can not only bend downward 90°, but also freely rotate 540°, which is more flexible than a human wrist; One robotic arm is equipped with a camera to "live broadcast" the patient's internal conditions on multiple screens in the operating room. The other three robotic arms can be equipped with different tools such as scissors, needle holders, and surgical forceps according to surgical needs.
The operation began. Dr. Ren cut six minimally invasive holes of about 1 cm in the patient's abdomen. One hole was used to place the camera, and three holes were placed for the three robotic arms for operation. The last two holes were placed. This hole allows two assistants next to the patient to assist Dr. Ren in performing some auxiliary operations.
During the operation, Dr. Ren sat on the console nearby, observing through a high-definition 3D camera while controlling the other three robotic arms.
The assistant is next to the patient and provides some assistance to Dr. Ren through the other two holes.
What are the advantages of Da Vinci surgery?
Da Vinci can participate in operations in almost all departments of surgery, but according to U.S. statistics, 20 are urological surgeries, 52 are gynecological surgeries, and 24 are general surgeries.
"Da Vinci is not specifically designed for urology. The reason why it is used more often in urology is because it is very suitable for working in small spaces. There are many surgeries in urology, such as prostate cancer. Radical surgery can also be performed with traditional laparoscopy, but the technical requirements for the doctor are higher. After becoming proficient in using da Vinci, the doctor will move faster, the operation time will be shortened, and the chance of postoperative complications such as urinary incontinence will be reduced. It will be reduced and the sexual nerves can be protected more accurately," Dr. Ren said.
Currently at their hospital, approximately 70 radical prostatectomies, 50 radical cystectomies and 50 partial nephrectomies are performed with the help of da Vinci.
