Shock! The First 4th Generation Da Vinci Robot in Southwest China "on Duty"


With the continuous development of medicine and the application of artificial intelligence, surgery is not limited to artificial operation, but may be done by surgical robot in the future. On June 27, the first fourth generation Da Vinci robot system in Southwest China was officially "on duty" in the Cancer Hospital Affiliated to Chongqing University. Jiang Yuequan, director of the chest cancer center, successfully performed resection for a lung cancer patient.

The 4th generation of Da Vinci robot system will be used in urology, chest cancer center, gynecological cancer center, gastrointestinal cancer center and other departments of the hospital.

Small trauma: only three 1-cm holes

The 4th generation of Da Vinci robot is very similar to "human". It is 1.9 meters tall, and handsome, and has a good appearance.

It is also different from "human", with complex internal structure and three heads and four arms.

“Three heads and four arms" refers to three operation platforms: doctor control platform, patient operation platform and video image platform, as well as four 540 degree flexible and free robot arms. Each of the three heads and four arms performs its duties and cooperates with each other, so as to operate for the patients more safely, accurately and efficiently.

Compared with the previous 3rd generation Da Vinci robot, the 4th generation has updated the design of the mechanical arm, the connection of instruments, etc., and specially optimized the design for complex cases and operations.

At 10 a.m. on the 27th, Liu Qing (a pseudonym) was pushed into the operating room. This year, it was diagnosed that she had a 2 cm ground glass nodule on her lung, which was initially determined to be the early stage of lung cancer. After considering the patient's condition, the doctor decided to let the Da Vinci robot perform the operation.

Jiang Yuequan first made three small holes with a diameter of less than 1 cm between her ribs, inserted the robot arm into the patient's chest through the holes, and then sat in front of the console 2 meters away from her, skillfully operating the robot arm for surgery. Less than 2 hours after the operation, Liu Qing's lung nodules were completely excised, the surrounding lymph nodes were cleaned, the amount of bleeding during the operation was small, and the suture was uniform and neat.

Advantages: surpassing traditional operation in an all-round way

Compared with traditional surgery and endoscopic minimally invasive surgery, the 4th generation Da Vinci robot has obvious advantages.

3D HD vision. The three-dimensional high-definition field of vision, which can be magnified up to 20 times, provides doctors with the experience of the operation and the unprecedented and excellent image of the operation.

Eliminate hand shaking and improve accuracy. The robot arm and instrument can accurately reproduce the human hand movement in the patient body without delay, and can rotate at 540 degrees, simulating the operation of human wrist in a narrow space. But it is more stable than hands, eliminating unnecessary shaking of hands, reducing the risk of surgery, and more stable and safer.

Reduce the number of surgeons and assistants. Only 1-2 doctors are needed to help the robot replace the surgical instruments.

The patients recovered quickly, and the risk of infection was reduced.

Wide application: most tumors can be removed

The 4th generation of surgical robot is widely used in clinic. All the diseases that can be treated by endoscopic minimally invasive surgery can be operated by the surgical robot. In addition, some traditional chest, laparoscopic surgery, which cannot carry out minimally invasive treatment, can also be very good application.

As a specialized Tumor Hospital, except for intracranial tumor and bone tumor, other tumor resection can be completed by the operation robot.

Increase in use: the total number of operations in China exceeds 100000

From year 2007 to now, the operation volume of Da Vinci robot has been increasing all over the country. In year 2018 alone, there were more than 30000 Da Vinci surgeries in China. By the end of 2018, there were more than 100000 surgeries in China.

After more than 10 years of development, the surgical robot has been relatively mature, which can better help doctors achieve closer to the ideal surgical results.

For doctors, the use of surgical robots can reduce the demand for anesthesia, the risk of infection, blood loss, etc. It allows doctors to have "three heads and six arms", more accurate and safer for complex and difficult operations.

Complementing each other. For patients, it can also benefit a lot from this new operation, such as: smaller incision, shorter rehabilitation time, fewer days in hospital, etc.
