Abstract: The disclosure provides an ultralow-carbon clinker-free cement, prepared from the following raw materials: granulated blast-furnace slag, gypsum and calcium oxide-based materials. The granulated blast-furnace slag accounts for 65%-95% of the total weight of the raw materials, the gypsum accounts for 4.5%-34.5% of the total weight of the raw materials, and the balance is the calcium oxide-based material. A weight percentage of calcium oxide and/or calcium hydroxide in the total weight of the raw materials is controlled to be 0.05%-0.75%. The disclosure further provides a method for preparing the ultralow-carbon clinker-free cement and application of the ultralow-carbon clinker-free cement in the preparation of concrete, mortar or cement products. The ultralow-carbon clinker-free cement of the disclosure has the advantages of high early strength, ultrahigh long-term strength, low shrinkage, carbonation resistance, low carbon emissions, etc.

Abstract: A forceps includes a first portion and a second portion. The first portion includes a shaft, an end effector assembly disposed at a distal end of the shaft, and a drive assembly including a drive bar. The end effector assembly includes jaw members movable between spaced-apart and approximated positions. The drive bar is slidably disposed within the shaft and coupled to the end effector assembly such that translation of the drive bar relative to the shaft moves the jaw members between the spaced-apart and approximated positions. The second portion includes a housing (or portion thereof) and a handle assembly including a movable handle that is coupled to the housing and movable relative thereto between first and second positions. The first and second portions are releasably couplable with one another to operably couple the movable handle with the drive bar such that moving the movable handle actuates the jaw members.

Abstract: A method of improving coercivity of an Nd—Fe—B magnet includes a first step of providing an Nd—Fe—B magnet having a first surface and a second surface. Next, a first solidified film of at least one pure heavy rare earth element is formed and attached to the first surface of the Nd—Fe—B magnet to prevent a reduction in corrosion resistance caused by oxygen and fluorine and hydrogen. After forming the first solidified film, the Nd—Fe—B magnet is subjected a diffusion treatment in a vacuum or an inert atmosphere. After the diffusion treatment, the Nd—Fe—B magnet is subjected to an aging treatment in the vacuum or the inert atmosphere.

Abstract: An articulation assembly for use with a surgical instrument is provided. The articulation assembly includes a plurality of joints, a plurality of cables, and a first drive member. Each joint defines a plurality of openings extending longitudinally therethrough, a central opening extending longitudinally therethrough, a pair of projections extending from a first surface, and a pair of grooves extending at least partially through a second surface. Each groove of at least one joint is configured to engage one projection of the pair of projections from an adjacent joint. Each cable extends through one opening of the plurality of openings of each joint. The first drive member extends through the central opening of each joint.

Abstract: An articulation assembly (200) for use with a surgical instrument (100) is provided. The articulation assembly (200) includes a plurality of joints (260), a plurality of cables (240), and a first drive member (220). Each joint (260) defines a plurality of openings (262) extending longitudinally therethrough, a central opening (263) extending longitudinally therethrough, a pair of projections (268) extending from a first surface, and a pair of grooves (266) extending at least partially through a second surface. Each groove (266) of at least one joint (260) is configured to engage one projection (268) of the pair of projections (268) from an adjacent joint (260). Each cable (240) extends through one opening (262) of the plurality of openings (262) of each joint (260). The first drive member (220) extends through the central opening (263) of each joint (260).

Abstract: An end effector assembly for a forceps includes first and second jaw members each having an opposed electrically-conductive tissue-contacting surface. The first jaw member is pivotable relative to the second jaw member between a spaced-apart position and an approximated position for grasping tissue between the opposed electrically-conductive tissue-contacting surfaces. The second jaw member includes an electrical cutting element and is translatable relative to the first jaw member between a first position, wherein the opposed electrically-conductive tissue-contacting surfaces are aligned with one another, and a second position, wherein the opposed electrically-conductive tissue-contacting surfaces are longitudinally offset relative to one another. Upon translation of the second jaw member between the first and second positions, the electrical cutting element is translated at least partially along the opposed electrically-conductive tissue-contacting surface of the first jaw member.
