Operations spine are undoubtedly one of the most complex interventions to which we can be subjected, along with cardiovascular or cerebral. In the specific case of the spine, and according to specialist surgeons, it is necessary that precision be maximized since only one millimeter of movement it may mean that the patient suffers from serious nervous sequelae.
Therefore, and bearing these elements previously described in mind, we must value the arrival of a new guided robot for spinal interventions as an important milestone, since it is a tool that makes this type of operation more precise every day. and safe.
In this sense, the Quirónsalud Barcelona Hospital has been the pioneer in Spain in having the robotic guidance platform for the spine in its facilities Mazor X StealthTM Edition, manufactured by Medtronic, which combines the tools necessary to carry out planning before the operation with instruments that assist and guide the surgeon during the operation. The result is 100% accuracy in spinal implant placement.
Safer and less invasive surgeries for patients
It is, in short, the use of a very high security platform, since, as the Dr. Pablo Clavel, director of the Clavel Institute of the Hospital Quirónsalud Barcelona, «Any small millimeter error can mean that the patient leaves with a neurological or nervous injury. The robot, in that sense, is much more exact because it guides us along the path that we have previously planned. And that for the patient, ultimately, what he means is more security.
The robot Mazor X Stealth ™ Edition It is indicated to achieve a precise placement of the implants used in spinal surgery, both percutaneous or minimally invasive as open. Thanks to the combination of advanced software, robotic technology and elements of navigation and instrumentation to assist the surgeon, a precise and safe trajectory is achieved in surgical procedures.
«At the moment we are using this new robot in the placement of instruments in spinal surgery. In addition, we are working so that it is able to also do other parts of spinal surgery, such as decompression of the nerves, or even help us in the resection of some tumors “, says Dr. Clavel.
Good planning of the intervention helps to prevent many of the problems that may arise later during its performance. In this sense, explains the specialist, the specific software that accompanies the Mazor XTM robot allows exact planning of surgery taking into account the characteristics of each of the patients.
The importance of planning
The planning platform allows generate three-dimensional images. Through an innovative process, the robot independently records and identifies each vertebral body to make planning of trajectories, size and implant placement even more accurate.
For this reason, Dr. Clavel points out, that «after the more than 50 cases that we have, experience allows us to say that this is a system that provides much more security and accuracy. And it is actually making the surgeries shorter. It is a minimally invasive surgery, faster and with less blood loss, since we don’t have to make such big wounds. This makes the surgery much safer and faster ”, explains Dr. Pablo Clavel.
Faster and with less blood loss
With its unique navigation technology, preoperative images and the preoperative plan are easily and directly fused with images obtained by scopy or intraoperative O-arm II CT, which provides even greater accuracy.
«We have the preoperative images prior to the intervention. We enter them into the robot’s computer and draw on the screen the exact trajectory and size of the instrumentation that we want to place in that patient.. The robotic arm then what it does is follow that direction, that implant size and that angulation that we have given it. All this allows us to achieve an accuracy that we do not have with any other system.», Clarifies the specialist.
The accuracy provided by the software and the presence of navigation cameras on the robot itself make image acquisition is quick and easy, so it is the navigation technology that works with the least amount of radiation possible. Thus, a 97.8% reduction in fluoroscopy time is achieved and a 98.2% reduction also in the radiation generated compared to conventional surgery.
Maximum benefit with minimal intervention
Technological advances such as these have allowed the development of minimally invasive surgeries, since surgeons have tools that allow them to carry out highly complex interventions through small incisions.
A new way of understanding surgery is helping to change the standard of surgical procedures. It is no longer just about the placement of an implant in the most efficient way possible, but it is intended that the entire procedure minimally affects the patient, looking for your maximum benefit. And the clinical evidence supports this approach to surgery.
In this way, there are studies that show how the use of these Robotic platforms in minimally invasive surgery reduce hospital stay by 27%, in 48% the rates derived from complications and up to 46% in revision cases.
