1/18/2024 0 Comments Operation nip and snipOne arm guides a laparoscope - a telescope-like endoscope - and two act as the surgeon's hands.Īcross the operating room, the surgeon sits comfortably in front of an ergonomically correct stereoscopic viewer. Designed at the German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt - DLR), the robot consists of three MIRO® robotic arms which are inserted in the patient's body through small incisions. Mirosurge is one such surgical robot which can assist the surgeon directly at the operating table. 'They could be easily configured for the specific demands of the actual operation,' he says. The robots under investigation in the Accurobas project belong to the new class of lightweight robots which leave a very small footprint, suggests the project manager, Dr Joerg Raczkowsky at KIT. The difference is that the surgeon uses robotic arms instead of endoscopes and tools, like the scalpel and clamp. While it may sound futuristic, robotic surgery is an extension of minimally invasive techniques. The Karlsruhe Institute of Technology (KIT) in Germany and its partners' goal with the Accurobas project was to overcome these limitations through robotics. That is why many complex surgical procedures still have to be done in the traditional 'more invasive' way. This method also requires good hand-eye coordination. The surgeon works with long, slender instruments that provide very little feedback and offer a limited view of the operating area through a single camera. One carries a fibre-optic camera and light source the other carries miniaturised surgical instruments. Typically, surgeons insert two small tubes and use what are called endoscopes. Not surprisingly, the trend is now moving towards minimally invasive surgery, performed through small incisions in the patient's skin to preserve healthy organs and tissue. This long incision is the scarlet letter of traditional surgery. Sometimes the damage done to the skin and muscle, to access the region of interest, causes greater injury than the curative procedure itself. When you hear the word 'surgery', the image of an incision large enough for the surgeon to see and feel the organ with his own eyes and fingers comes to mind.
