Abstract: Apparatuses, including sleeves, intraoral scanning systems to use these sleeves, and methods of using the sleeve. These sleeves may preserve the optical performance of the scanner while also providing a physical protection to the scanner itself, and may cover the entire intraoral scanner (e.g., the wand and/or connecting cable) or only the tip of the scanner (e.g., the wand portion) to prevent contamination.

Abstract: A cage device includes first and second segments pivotally connected by a hinge. Pivoted movement of the segments with respect to each other is limited by a first stopper portion of the first segment abutting against a second stopper portion of the second segment.

Abstract: Removable barrier devices (e.g., sleeves) for covering medical scanning devices to reduce the chance of cross-contamination between patients and/or to protect the scanning devices from physical damage. The barrier device can include a cover that has an integrated window for passing optical signals between the scanning device and an external environment. The cover can include a sleeve that covers a handle portion of the scanning device to prevent contamination of the handle from a user's hand or glove. The cover and sleeve may both be formed of the same flexible material, or the cover may be rigid to maintain the window in a fixed position and the sleeve may be flexible to allow a user to activate a button or touchpad on the handle. An interface region between the cover and sleeve may provide a hermetic seal. The window may include a nanostructured antireflective material to limit internal reflections.

Abstract: An elastic device providing means of controlling its stiffness by controlling the tension of the string or group of springs resulting in adjustable transverse stiffness of it, arranged in matrix to enable the control of spatial stiffness of a 2D matrix in unlimited resolution.

Abstract: A tool assembly includes at least one tube and a slider disposed on a distal portion of the at least one tube. The slider includes a distal limiter movable between an extended position, in which the limiter protrudes distally from the slider, and a contracted position, in which the limiter does not protrude distally from the slider.

Abstract: A cage device includes a first support member which has a bone contact surface and from which depend side surfaces that are provided with ratchet teeth. The first support member ratchets with a ratchet member, which in turn ratchets with a ratchet wall, such that the first support member and the ratchet member are movable independently of each other and form a multiple sliding mechanical mechanism.

Abstract: An intervertebral cage includes first and second support surfaces arranged for pivoting about a pivot, and one or more lifting cams and an actuating shaft for actuating the cams. Actuation of the cams causes non-parallel movement of one of the first and second support surfaces with respect to the other support surface.

Abstract: An expandable bone device that includes a plurality of linking elements pivotally connected to one another about a hinge, wherein each of the linking elements has upper and lower support plates. An expansion mechanism is operatively connected to the linking elements and can move the upper support plate closer or further with respect to the lower support plate.
