摘要： A surgical retractor includes a plurality of blade assemblies interconnected by a plurality of racks. One or more of the blade assemblies is movable along a rack to selectively expand the retractor. At least one of the blade assemblies includes a blade that is rotatably connected to the blade assembly and that is rotatable independent of other blades of the retractor.

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 integrally connected to the first implant engaging member by a pair of opposed integral spring members located proximal to 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 pair of opposed spring members 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： Instruments and methods are provided for manipulating a bone anchor and a spinal fixation element. The instruments and methods disclosed herein are particularly suited to facilitate rotation of a bone anchor relative to another bone to correct the angular rotation of the vertebrae attached to the bone anchor. The instrument does not require the spinal fixation element to be inserted into the bone anchor prior to manipulation. The instrument further may be used in the insertion of the spinal fixation element into the bone anchor.

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.

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： 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.
