Drs. Maximilian Kückelhaus and Tobias Hirsch from the Centre for Musculoskeletal Medicine at the University of Münster in Germany recently performed the first completely robot-supported microsurgical operations on humans using a new method in which a robot designed for microsurgery is networked with a robotic microscope.
The robot mimics human hand movements with an electromagnetic field and joysticks. Via tiny surgical instruments, the surgeon’s movements are reduced in size by up to 20 times, which eliminates the shaking that may be present in human hands. Five operations have been successfully performed, with more set to follow. The approach is described as ideal for use on breast cancer patients who need complex reconstructions or after accidents in which patients need tissue transplants.
"Our hope is that with this new method we can not only perform operations with a greater degree of precision and safety but also, in the case of the tiniest structures, go beyond limits imposed by the human body," says Dr. Kückelhaus. "This new method for operations enables us to work with a much higher degree of delicacy and precision than is possible with conventional operating techniques. As a result, less tissue is destroyed, and patients recover faster."
The technology makes it possible for the surgeon to remove themselves completely from the sterile field, theoretically allowing them to operate more comfortably. "As we can now operate on patients in a remote fashion, we have much better ergonomics," says Dr. Hirsch. "This protects us from fatigue, and that means that our concentration can be maintained over a period of many hours. In initial studies involving the systems, we were already able to confirm the positive effects on the quality of operations and on ergonomics."
While such technology is not likely to be widely available to surgeons for some time, it exemplifies the inexorable direction in which microsurgery is headed.
