How do robots do surgery?


Surgical robotic systems, are hardware devices used to assist in surgical procedures. The use of robots to do surgery has become increasingly popular, and many large hospitals in China have introduced surgical robot systems and used them in surgical operations. It is characterized by high precision, stable operation and repeatability, etc. In terms of minimally invasive surgery with high precision requirements, surgical robots have brought great clinical benefits to minimally invasive surgery patients.

Are surgical robotic systems a panacea?

Surgical robotic systems are not a panacea, but they can help doctors solve many problems. Surgical robots can provide greater precision and better control, resulting in fewer surgical errors and higher surgical success rates. In addition, they can provide a better field of vision, making it easier for the surgeon to see the surgical area. Surgical robotic systems can also help doctors better handle complex surgical tasks.

The surgical field of view of the surgical robotic system is a naked-eye 3D effect, which provides a more realistic three-dimensional visual perception. It is equivalent to putting your eyes in the abdominal cavity, which is 5-10 times clearer than traditional laparoscopy, and it can also be rotated to observe in full angle, which makes the observation more careful and comprehensive, and the operation more on point. And the main surgeon only needs to sit in front of the operating table to operate, greatly reducing the impact of physical strength and energy loss.

The robotic arm and instruments of the surgical robotic system are also more sensitive and delicate than traditional hand-held instruments. The robotic arm of PUMAI’s surgical robot system has 6 degrees of freedom and can rotate 360 degrees without dead angle, allowing it to enter narrow anatomical areas of the human body that are inconvenient for human hands to operate. There is also a stabilizer on the robotic arm that can automatically filter out artificial trembling, which has stability and precision that is incomparable to that of human hands, and can achieve zero bleeding during the operation and higher surgical safety.

Application Scenarios of Surgical Robot System

How does a surgical robotic system perform surgery?

The operation process of the surgical robotic system needs to go through the following steps:

Step 1: Pre-surgical preparation

The surgical robotic system needs to be prepared before surgery, including installing surgical instruments, debugging the robotic system, and sterilizing the surgical area.

Step 2: Robot Positioning

The surgical robotic system needs to determine the position and attitude of the surgical area by means of a positioning system in order to arrange the position and orientation of the robotic arm. The surgeon needs to position and adjust the surgical area on the console.

Step 3: Surgical Operation

The robotic arm of the surgical robotic system inserts surgical instruments into the surgical area for operation. The surgeon controls the position and direction of the robotic arm through the handles and foot pedals on the console to perform the surgical operation.

Step 4: End of Surgery

After the surgery, the surgical robotic system needs to be cleaned and sterilized for the next use.

As technology continues to evolve, surgical robotic systems will become more and more powerful, bringing better treatment results to patients. However, surgical robots are more costly and have more restrictions on their use, and are only suitable for some complex surgical operations. In the future, with the further development of technology and cost reduction, surgical robotic systems will play a more extensive role in the medical field.
