The fourth generation of new technology that subverts traditional surgery - Da Vinci surgical system
Release date: 2014-05-13
A few days ago, the University of Miami Hospital announced that it was the first teaching hospital to use the new generation (fourth generation) Da Vinci Xi surgery system. The system was approved for use by the US Food and Drug Administration on April 1, 2014. Its introduction was mainly due to the generous donation of Mr. Paul J. DiMare and his wife.
The Da Vinci Surgical System is a robotic surgical system that assists complex surgery in a minimally invasive manner. It was developed and designed by Intuitive Surgical. It was officially approved by the US Food and Drug Administration in 2000. This surgical system was originally used primarily for minimally invasive surgery in urology, such as prostatectomy, and is now increasingly used in surgical minimally invasive surgery such as cardiac surgery, gynecology, and pediatric surgery. At present, the Da Vinci surgical system has been used by hospitals all over the world. As of 2012, more than 200,000 surgeries have been performed by Da Vinci robots. The popularity of surgical robot technology represented by Da Vinci has raised the precision of surgery to a whole new level, bringing surgery to a new era.
As the Da Vinci surgical robot representing the highest level of surgical robots today, it is mainly composed of three parts: 1. The main surgeon operating console; 2. The 3D imaging video imaging platform; 3. The mechanical arm, the camera arm and the surgical instrument mobile platform. During the operation, the surgeon does not directly contact the patient, and is operated and controlled by the three-dimensional vision system and the motion calibration system. The mechanical movement and the surgical operation are completed by the robot arm and the surgical instrument simulation.
Compared with traditional laparoscopic surgery systems, surgical robots have obvious advantages:
(1) 3D high-definition imaging technology provides high-definition, all-dimensional stereoscopic surgical vision for the surgeon, which can accurately organize the tissue;
(2) The doctor controls the robot arm through the doctor's console, and the operation mode respects the doctor's open surgical operation mode, reducing training and learning;
(3) The simulated wrist surgical instrument eliminates the vibration and reduces the risk of surgery;
(4) The robot can simulate the flexibility and accuracy of the human finger, and can perform fine operations in a small space that cannot be touched by human hands;
(5) The joint wrist of the robot hand has multiple degrees of freedom of movement, which expands the operating ability of the operator and improves the accuracy of the operation;
(6) A surgeon can complete all the work of a laparoscopic surgery team, reducing the coordination errors and making it easier for the surgeon to achieve the intention;
(7) The patient's incision is smaller, the recovery time is shorter, and the risk of infection is greatly reduced;
(8) The surgeon's sitting operation in a sitting position is conducive to long-term complicated surgery and prolongs the surgeon's surgical life.
Therefore, the surgical robot system is absolutely revolutionary innovation for surgery, which not only reduces the surgical trauma to a greater extent, but also improves the efficiency of the doctor. More importantly, it improves the surgical effect and advances the surgery. Provides more possibilities.
With the continuous development of robot systems, Da Vinci robots are constantly being updated. The third generation of products commonly used in the market, Da Vinci Si system. The robot is already in place in real-time operation, but the operating range of the operation is limited. If the doctor wants to continue to explore the pathology of other parts of the patient or deeper parts of the body, it needs to be repositioned. Recently, IntuitiveSurgical released the fourth generation of its robotic surgery system, the Da Vinci Xi system. The latest fourth-generation model Xi is better than the previous generations.
(1) The greatly improved driving structure makes the range of movement of the robot arm more flexible and precise, and can cover a wider surgical site;
(2) The digital endoscope is more lightweight, uses laser positioning and can automatically calculate the optimal surgical posture of the mechanical arm, the image is more clear, and the 3D stereoscopic effect is more accurate;
(3) The endoscope can be detachably connected to any one of the robot arms, and the surgical field of view is wider;
(4) Smaller, thinner robots with newly designed wrists provide unprecedented flexibility for surgical procedures;
(5) The longer stent design provides doctors with a larger range of surgical procedures.
In fact, the biggest feature of the Da Vinci XI system is the design of its four minimally invasive scalpels, and the rotatable bracket is designed to rotate to any part of the body. More importantly, if the doctor thinks it is necessary, the four minimally invasive scalpels can be removed and re-implanted inside the body. In addition, the Da Vinci Xi system is compatible with Intuitive Surgical's Firefly Fluorescence Imaging System, which provides physicians with more real-time visual information including blood vessel testing, bile duct and tissue perfusion. The DaVinci Xi system is highly scalable, providing a seamless connection to a range of imaging and instrumentation technologies. The advent of a new generation of robotic surgical systems that perfectly solves the limitations of previous generations of systems can help surgeons perform more complex operations. With the continuous innovation and development of science and technology and surgical concepts, the application field of Da Vinci robotic surgery will continue to expand and develop. Coupled with the development of telemedicine and telesurgery, the era of embarrassing robotic surgery will soon come.
This latest generation of robotic surgery systems has been officially launched at the University of Miami's Sylvester Cancer Center, making it one of the patient's surgical options. It provides state-of-the-art medical technology for patients with complex surgery and helps Miami University Hospital become a well-deserved leader in prostate cancer surgery.
