    Abstract: Gas-tight seal assemblies for use during minimally invasive surgery include various aspects. A wiper seal includes a sealing portion and a surrounding flex portion. Upper and lower faces of the sealing portions are angled with reference to an inserted instrument, the upper face's angle being more acute with reference to the instrument's shaft than the lower face's angle. The flex portion is corrugated, support ribs are in one or more corrugation grooves, and the support ribs allow the groove to easily collapse but resist the groove widening. The support ribs also prevent the sealing portion from inverting. An instrument insertion guide is positioned over the sealing portion and moves laterally with the sealing portion. A latch piece removably secures the seal assembly to a cannula. An anti-inversion piece prevents the wiper seal from inverting when an instrument is withdrawn. An assembly may include various combinations of the seal assembly, a cannula, a surgical instrument, an obturator, an endoscope, and a teleoperated medical device. The seal assembly may rotate within a cannula. The seal assembly may be used during manual or teleoperated surgery.

    Abstract: A medical device includes an instrument sterile adapter (ISA) that includes a first plate and a second plate. The first plate includes a mounting surface and a plurality of landing pads. The mounting surface provides a first datum plane for mounting the ISA on a carriage that includes actuators. The plurality of landing pads extend through the second plate and provide a second datum plane for a surgical instrument coupled to the ISA such that the first datum plane and the second datum plane are parallel surfaces separated by a fixed distance. The medical device may include a plastic sheet having opposing first and second sides with the first plate located on the first side and the second plate located on the second side. 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.

    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 translation: 本公开涉及用于诸如立体内窥镜的成像系统的校准目标装置,组件和方法。 校准组件包括:目标表面在三维上延伸有校准标记和具有接合内窥镜的界面的主体,使得标记在视野内。 第一校准标记沿着目标表面的第一平面延伸,并且第二标记沿着目标表面的第二平面延伸。 相对于通过内窥镜观察的视野,平面是不同的和不对称的。 特别地,三维目标使得能够使用单个图像(或立体内窥镜的一对图像)进行内窥镜校准,以减少校准过程的复杂性,校准时间和错误的机会以及允许在不同焦点的相机的有效校准 职位
