摘要： Methods and devices are provided for reducing a spinal fixation element into a spinal implant element. In one exemplary embodiment, a spinal rod reduction device is provided for reducing a spinal fixation element into a spinal implant element. The spinal rod reduction device can include a fastener engaging member for engaging at least a portion a spinal implant element, a reduction member for engaging at least a portion of a spinal fixation element, and a handle assembly mated to the reduction member. The handle assembly can be designed in such a way that actuation of the handle assembly causes movement of the reduction member relative to the fastener engaging member and the movement of the reduction member reduces the spinal fixation element into the spinal implant element. Two different styles of spinal rod reduction devices are discussed in detail. Various techniques are also provided for reducing a spinal fixation element into a spinal implant element.

摘要： An instrument for engaging a bone anchor may include a first implant engaging member having a proximal end and a distal end and a second implant engaging member having a proximal end and a distal end. The second implant engaging member may be pivotally connected to the first implant engaging member about a pivot point located proximate the distal ends of the first and second implant engaging members. Manipulation of the proximal ends of the first and second implant engaging member can cause each of the distal ends to rotate about the pivot point to engage at least a portion of a bone anchor. A rod adjusting tool may be connectable to the bone anchor engaging tool and may be axially adjustable relative to the bone anchor tool to adjust a spinal rod relative to the bone anchor.

摘要： The present invention provides methods and devices for reducing a rod disposed within or adjacent to a rod-receiving head of a spinal implant. In general, a rod reduction device is provided that can removably mate to the rod-receiving head of a spinal implant and be effective to reduce a rod disposed within or adjacent to the rod-receiving head. In an exemplary embodiment, the rod reduction device can include a clamping member that is adapted to removably mate to a rod-receiving head of a spinal implant and a rod-reducing arm that is rotatably matable to the clamping member. The rod-reducing arm can be configured such that rotation of the arm with respect to the clamping member is effective to reduce a rod into the rod-receiving head of the spinal implant that is mated to the clamping member.

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。
