Abstract

An endoscopic surgery system can have an endoscope with a hub, shaft and working tip. An energy source can use a fiberoptic cable and a working channel that both extend through the shaft to the tip. A camera at the working tip can be surrounded by a resilient layer and supported by a support structure within the tip. The structure can aim the camera and energy toward a working zone. The structure can also ease surgical tools in the working channel past the camera to the working zone, while the resilient layer stretches. The structure can have a control that facilitates camera and beam aiming. The structure can have a bending frame and multiple appendages that interface with elongate structures such as cables, tools, and channels. The appendages can have guiding surfaces to facilitate tool passage and protect the camera. The structure, resilient layer, and other aspects can cooperate to facilitate insertion of tine tools, and micro-endoscopic sizes for the most delicate surgeries.
