Surgery with robots is a very “high class” medical technology in the eyes of many people, and while they are in awe, they are also full of questions – “Can surgery with robots really be as detailed as manual surgery? Is robotic surgery ‘anything is possible’?”
The full name of the surgical robot is the Endoscopic Surgical Instrument Control System, a new type of minimally invasive surgical device. The principle of this surgical equipment is similar to that of laparoscopy, simply put, laparoscopy is manually operated by a doctor, while “da Vinci” replaces the doctor’s hands with a remote-controlled robotic arm system; in another room across the wall, the surgeon operates the robotic arm through a console to perform many complex actions such as incision, separation, and suturing inside the patient.
It can be said that the treatment strategies of laparoscopic surgery and robotic surgery are the same, but the difference is that robotic surgery will be more delicate and has many advantages over laparoscopy in operating difficult surgeries (traumatic, long and difficult): 1. The imaging of laparoscopic surgery is two-dimensional, the field of view can be enlarged up to 3 times, and the operating instruments are rigid with limited mobility; while robotic surgery is three-dimensional imaging In contrast, robotic surgery is three-dimensional imaging, which can magnify the field of view 6 to 10 times, and the robotic arm has a high degree of freedom of operation and can rotate 540°. Professor Wang said, “the robot seems to let itself drill into the patient’s stomach, the cut tissue can be cut off, but also flexible to avoid other nerves, blood vessels, to avoid damage”; 2, laparoscopy is manual through the principle of leverage to operate the instrument, the operation of the subtle movements in the abdominal cavity will be magnified, easy to cause hands fatigue, tremors The laparoscope is manually operated by the lever principle, and the subtle movements during operation will be magnified in the abdominal cavity, which will easily cause hand fatigue and tremor and bring inconvenience to the operation. During the operation of the main surgeon, it is also necessary to monitor the operation position by an assistant operating the observation mirror, which has the problem of cooperation between two people and makes the operation less efficient. However, for robotic surgery, these problems do not exist; 3. Surgery time: robotic surgery is the same as laparoscopic surgery, which requires inflating the patient’s abdominal cavity and then, in the appropriate surgical position, placing a poke card, which is used to deliver surgical instruments to a designated location in the body. Although robotic surgery requires the installation of a robotic arm and commissioning after this set of procedures, which will take up a few more minutes; however, because robotic surgery is flexible and easy to operate, the total length is somewhat shorter than laparoscopy for more difficult procedures.
