摘要： A dental scanning system comprises an intraoral scanner and one or more processors. The intraoral scanner comprises one or more light projectors configured to project a pattern (comprising a plurality of pattern features) on a dental object, and two or more cameras configured to acquire sets of images, each comprising at least one image from each camera. The processor(s) are configured to determine a correspondence between pattern features in the pattern of light and image features in each set of images by determining intersections of projector rays corresponding to one or more of the plurality of pattern features and camera rays corresponding to the one or more image features in three-dimensional (3D) space based on calibration data that associates the camera rays corresponding to pixels on the camera sensor of each of the two or more cameras to the projector rays.

摘要： A catheter system includes a catheter that includes an outer shaft and a rotatable inner shaft having a drill tip body. A distal portion of the outer shaft may include a collar that is configured to releasably engage with the drill tip body so that the collar can rotate with the drill tip. The drill tip body and the collar may include locking features that allow the drill tip body to advance within and rotationally couple with the collar. The catheter can be configured to bend laterally when the inner shaft is rotating within the other shaft for maneuvering within a blood vessel, for example, as the drill tip crosses an occlusion. The catheter may include a flushing feature to flush a distal region of the catheter to improve visibility for an imaging element of the catheter.

摘要： An endoscope may include a shaft having a longitudinal axis, a first image sensor facing a distal direction, and a second image sensor facing a lateral direction. The endoscope may further include a tubular member having a lumen, the lumen having a distal-end opening and defining a longitudinal axis through a center of the lumen. The tubular member may be movable between a first configuration and a second configuration. In the first configuration of the tubular member, the longitudinal axis of the lumen may be parallel to the longitudinal axis of the shaft. In the second configuration of the tubular member, the longitudinal axis of the lumen may extend through a lateral opening in a wall of the shaft.
