    摘要： The present invention is directed to a transconnector for coupling first and second spinal fixation rods or other elongate fixation elements. The transconnector includes a male member, a female member, and a locking member. The male member has a body with a linking element (such as a hook) associated with the lateral end for receiving one of the fixation elements, and a projection on the medial end. The projection includes a recess defined by lateral and medial walls. The female member has a body with a linking element associated with the lateral end for receiving the other fixation element, and a cavity with an opening on the medial end for receiving a portion of the male member projection. The locking member secures the position and orientation of the male member projection portion in the cavity in order to accommodate different separation distances and orientations between the first and second fixation elements. The locking member cooperates with the medial wall of the recess of the projection to prevent uncoupling of the male and female members. The male member may be made as a two component assembly in which the two components can rotate relative to one another for accommodating rod convergence or divergence.

    摘要翻译： 本发明涉及一种用于联接第一和第二脊柱固定杆或其它细长固定元件的横向连接器。 横连接器包括阳构件，阴构件和锁定构件。 阳构件具有主体，其具有与侧端相关联的连接元件（例如钩），用于接收其中一个固定元件，以及在内侧上的突起。 突出部包括由侧壁和内侧壁限定的凹部。 阴构件具有主体，其具有与侧端相关联的连接元件，用于接收另一固定元件，以及具有在内侧上具有用于接收阳构件突出部的一部分的开口的空腔。 锁定构件固定阳构件突出部分在空腔中的位置和取向，以便适应第一和第二固定元件之间的不同间隔距离和取向。 锁定构件与突起的凹部的内侧壁配合以防止阳构件和阴构件的脱开。 阳构件可以制成双组分组件，其中两个组件可以相对于彼此旋转以容纳杆会聚或发散。

    摘要： Iron and steel rolls are ground to production quality requirements with a grinding wheel that requires minimal wheel wear compensation, profile error compensation or taper error compensation during the grinding process. The grinding wheel consists essentially of a superabrasive material selected from the group of natural diamond, synthetic diamond, cubic boron nitride, and mixtures thereof, in a bond system, for a grinding wheel with extended wheel life, and which removes minimum amount of stock off the roll to achieve desired roll geometry.

    摘要： A hand tool having first and second handle portions and a toothed bar that has first and second terminal ends, a plurality of teeth having free ends, and at least one shield member adjacent the teeth and having at least a portion which extends beyond the free ends of the teeth, wherein the toothed bar is pivotally attached at its first terminal end to a first handle portion and the teeth of the toothed bar engage with a pawl associated with the second handle. The invention is also directed to a safety ratchet mechanism for preventing undesired relative movement of two handle portions of a hand tool, wherein the toothed bar has a first end that is pivotally connected to at least one handle portion and a second end adapted and configured to move relative to the second handle portion when the handle portions undergo relative movement, and wherein the toothed bar has a plurality of teeth that are designed to interact with a pawl. The toothed bar may further have two shield members with the teeth extending therebetween to further shield the operator's hands or gloves from the teeth. The second handle portion may have an opening through which the toothed bar can slide, and a catch may be mounted on the toothed bar to prevent it from sliding out of the opening, and a stop may be associated with the handle to prevent the second end from being disassociated with the handle portion.

    摘要： A fastener assembly for a spinal fixation system that is particularly useful in treatment of pediatric and small-statured patients includes a fastener, an attachment member, and a locking member. The fastener has a lower portion for contacting a bone and an upper portion integral with the lower portion. The upper portion has two open channels. Each channel is configured and dimensioned to receive a portion of a longitudinal or connecting member along its circumference. The attachment member is positionable on the fastener and at least partially covers the channel that receives the longitudinal or connecting member. The locking member is operatively associated with the upper portion of the fastener and secures the attachment member and the longitudinal or connecting member to the fastener.
