    Abstract: A cannula and instrument guide assembly includes a cannula with a proximal portion and a tube, An instrument guide is removably inserted into the proximal portion of the cannula and extends through the cannula to a distal end of the tube. The proximal portion of the cannula has an insufflation port. The instrument guide provides at least one interior passageway to support a shaft of a surgical instrument that passes through the instrument guide. One or more channels on an outer surface of the instrument guide provide a passage for insufflation gas received from the insufflation port to the distal end of the tube, The one or more channels have a first cross-sectional area at a proximal end and a second, larger cross-sectional area at a distal end. The one or more channels may have the first cross-sectional area along a majority of the length of the channels.

    Abstract: The present disclosure relates to calibration target devices, assemblies and methods for use with imaging systems, such as a stereoscopic endoscope. A calibration assembly includes: a target surface extends in three dimensions with calibration markers and a body with an interface that engages an endoscope so the markers are within the field of view. A first calibration marker extends along a first plane of the target surface and a second marker extends along a second plane of the target surface. The planes are different and asymmetric relative to the field of view as seen through the endoscope. Three-dimensional targets, in particular, enable endoscopic calibration using a single image (or pair of images for a stereoscopic endoscope) to reduce the calibration process complexity, calibration time and chance of error as well as allow the efficient calibration of cameras at different focus positions.

    Abstract: An instrument sterile drape includes a plastic sheet and an instrument sterile adapter (ISA) coupled to the plastic sheet. The ISA includes a bottom plate located on a first side of the plastic sheet and a top plate located on a second side of the plastic sheet and joined to the bottom plate. The bottom plate includes a mounting surface that provides a first datum plane for mounting the ISA on a carriage that includes actuators and a plurality of landing pads that extend through the top plate to provide a second datum plane for a surgical instrument coupled to the ISA such that a distance between the carriage and the surgical instrument is controlled only by the bottom plate. The instrument sterile drape may include a pouch shaped to fit around the carriage with the ISA capturing the pouch between the top and bottom plates.
