A new steerable endoscope for minimally invasive surgery is provided. The endoscope system includes: a wireless steerable endoscope (), an external magnetic controller () and an image/video display (). The wireless steerable endoscope () could be inserted through an incision (-) on the body skin () and be anchored/steered inside the body cavity by the external magnetic controller (). It is shaftless, wireless, and can be steered inside the body, operating in a remote manner. Compared with existing endoscopes, it neither requires additional incision nor does it occupy trocar or port space. Without the endoscope shaft, the surgical access trauma and incision size can potentially be reduced, avoiding endoscope-instrument fencing. It can be placed remotely from the access incision, providing an improved and wider field of view. It is soft-bodied and compact in structure, therefore safety is high. More than one wireless endoscope can be placed into the operating cavity, providing simultaneous multiple video images of different viewing angles. These features allow safer, more efficient and less traumatic surgery by reducing trocar size or number.
