A medical targeting system facilitates guidance of a real-time imaging system and intervention tool to a calibrated position of a target identified in preprocedural images. Real-time images from an imaging system are registered with preprocedural images. The imaging device is guided to the vicinity of a virtual target identified from the registered preprocedural images until the physical target is identified in the real-time images. The virtual target position can then be calibrated to correspond to the physical target. Once calibrated, an intervention tool can be guided to the calibrated position to perform the procedure, even if the real time imaging no longer shows physical target. The imaging device may include a near infrared fluorescence (NIRF) fiberscope that enables imaging of targets outside of the anatomical channel or other pathway being traversed by the imaging device.

The utility model discloses a deformable enteroscopy treatment tool belongs to enteroscopy technical field, including inner tube, outer tube, convex membrane, dosing pipe, gasbag pipe, fiberscope, the inner tube is covered and is established in the inside of outer tube, and the right -hand end of inner tube and outer tube is closed end, and the right -hand end fixed mounting of inner tube has convex membrane, and the inside of inner tube is provided with fiberscope, a plurality of dosing pipes are all fixed mounting on the outer wall of outer tube, and a plurality of dosing pipes are on the outer wall of outer tube and are distributed in the equal interval of circular array, a plurality of gasbag pipes are all fixed mounting on the right -hand end outer wall of outer tube, and a plurality of gasbag pipes are on the outer wall of outer tube and are distributed in the equal interval of circular array.
