    • A bone plate includes at least one torsional modification feature (TMF). Each TMF is structured to decrease the torsional rigidity of the plate relative to longitudinally opposite portions, but may be modified to increase the torsional rigidity thereat. Each TMF is defined by beams contiguous with the lateral sides of the plate, and an opening extending laterally therebetween. In a preferred embodiment, opposed projections extend into the opening to define threaded discontinuous wall portions for receiving an insert, such as a set screw. In one embodiment, bioabsorbable and/or bioactive inserts may be used to temporarily increase the torsional rigidity of the plate during initial fixation and thereafter have reduced torsional rigidity to mimic normal callus. The plate is preferably used with fixed angle fasteners that may be subject to high torsional loads post-operatively.
    • 骨板包括至少一个扭转修改特征(TMF)。 每个TMF被构造成降低板相对于纵向相对部分的扭转刚度,但是可以被修改以增加其上的扭转刚度。 每个TMF由与板的侧面相邻的梁以及横向延伸的开口限定。 在优选实施例中,相对的突出部延伸到开口中以限定用于接收插入件(例如固定螺钉)的螺纹不连续壁部分。 在一个实施方案中,可以使用生物可吸收和/或生物活性插入物来暂时增加初始固定期间板的扭转刚度,此后具有降低的扭转刚度以模拟正常愈伤组织。 该板最好与固定角紧固件一起使用,固定角紧固件可能在操作后经受高扭转载荷。

    • A surgical instrument includes an end effector having a clevis and first and second jaws mutually rotatable between open and closed positions. The jaws are proximally directed and laterally displaced relative to an axis of a control shaft of the instrument. The jaws hold first and second parts of a fastener, respectively. The first part includes a base having tissue-piercing posts, and the second part includes a second base defining apertures receiving the posts and a portion movable relative thereto between first and second orientations. When the posts are inserted into the apertures, the movable portion can be moved from the first unlocked orientation into the second configuration to lock the fastener parts together in an implanting position determined by various alignment measures, including markings or flags on the jaws or at the housing. The instrument is adapted to move the second part into the second configuration.
    • 手术器械包括端部执行器,其具有U形夹以及在打开位置和闭合位置之间可相互旋转的第一和第二钳口。 夹钳相对于仪器的控制轴的轴线向近端引导和横向移位。 夹爪分别固定紧固件的第一和第二部分。 第一部分包括具有组织穿刺柱的基部,并且第二部分包括限定接收柱的孔的第二基部和在第一和第二取向之间相对于其移动的部分。 当柱插入孔中时,可移动部分可以从第一解锁方向移动到第二构造中,以将紧固件部件锁定在由各种对准措施确定的植入位置中,包括在钳口上的标记或标记 住房。 该仪器适于将第二部分移动到第二配置中。
