606295000 | Screw head cover | 13 |
20080288001 | CERVICAL PLATE LOCKING MECHANISM AND ASSOCIATED SURGICAL METHOD - The cervical plate locking mechanism of the present invention is elegant in its design and effective in its performance, and utilizes a plate with holes that each incorporate a locking lip structure and locking screws that each incorporate a head portion having petal structures that are outwardly biased prior to insertion via an internally-disposed c-ring or the like. Advantageously, the lead-in torque of each of the locking screws is less than the lead-out torque of each of the locking screws. Thus, reverse threading or backing out is prevented. Alternatively, the cervical plate locking mechanism of the present invention utilizes a locking plate having petal structures that are inwardly biased prior to insertion of the head portion of the locking screws via an externally-disposed c-ring or the like. | 11-20-2008 |
20090082815 | SPINAL STABILIZATION SYSTEM WITH TRANSITION MEMBER - A spinal stabilization system generally comprises an anchor member configured to be secured to the patient's spine, a transition member received by the anchor member, and a flexible element coupled to the transition member. The transition member is positioned between a rigid member and a flexible member, which are each adjacent to the flexible element. | 03-26-2009 |
20110238123 | IMPLANT PLATE SCREW LOCKING SYSTEM AND SCREW HAVING A LOCKING MEMBER - Spinal fusion system and method utilizing an implant and screw, wherein at least one pawl is mounted on or integral with the screw to prevent said plate or screw from moving in at least one of an axial direction or a rotational direction. | 09-29-2011 |
20120035665 | Orthopedic Plate Blocking Assembly - In an exemplary embodiment, the present invention provides an orthopedic plate blocking assembly that can be used for the fixation or fastening of an orthopedic plate to bone tissue. In particular, the present invention, in one embodiment, provides an orthopedic plate having a plurality of cavities where each cavity is configured and dimensioned to receive a bone anchoring member. The orthopedic plate further provides a blocking mechanism having a plurality of blocking members that block the bone anchoring members to prevent the bone anchoring members from “backing out” of cavities once the bone anchoring members are finally seated in the cavities. | 02-09-2012 |
20120191141 | BONE FIXATION SYSTEMS AND METHODS - A bone fixation plate includes a first opening formed in a plate that is configured to receive a first fastener; a second opening formed in the plate that is configured to receives a second fastener, and a retention member that extends into a third opening formed in the plate between the first opening and the second opening, wherein the retention member is elastically deformable between at least three positions. | 07-26-2012 |
20130218211 | RETAINING MECHANISM - A retaining mechanism for use in affixing a stratum to bone is disclosed. The retaining mechanism comprises a stratum, a retaining element and a spring element. The stratum comprising a first surface, a second surface, and a hole extending between the first surface and the second surface, wherein the second surface is configured to engage at least a portion of the bone. The retaining element comprises a first position that permits a fastener to be passed through the hole, and a second position that at least partially overlaps the hole. The spring element is configured to engage the stratum and configured to engage the retaining element such that the spring element helps maintain the retaining element in its second position so as to help prevent inadvertent backing out of the fastener after the fastener has been fully inserted into the hole. | 08-22-2013 |
20150066096 | CERVICAL PLATE WITH A FEEDBACK DEVICE FOR SELECTIVE ASSOCIATION WITH BONE SCREW BLOCKING MECHANISM - A bone plate having at least one screw hole adapted to receive a bone screw, a blocker having a blocking end for blocking a bone screw from further backout of bone the blocker being predisposed in a blocking position wherein the blocking end at least partially overlaps a portion of the screw hole, the blocker being moveable from the blocking position by contact with the bone screw during insertion of the bone screw into the screw hole, and a blocker fixation element having an open orientation at which the blocker can move from the blocking position and a closed orientation preventing substantial movement of the blocker from the blocking position. The blocker fixation element cannot be moved to the closed orientation unless the screw head passes the blocker, thereby revealing that the blocker fixation element is in position to prevent substantial movement of the blocker. | 03-05-2015 |
20150320453 | VERTICAL INLINE PLATE - A spinal plate having an upper surface and a lower surface, the lower surface adapted to contact bone. A plurality of holes extend from the upper surface to the lower surface through the plate which is configured and adapted to receive bone fasteners for fixing the spinal plate to bone. The lower surface of the spinal plate comprises a ridge that protrudes from the underside of the plate and encloses the plurality of holes spaced inward from the perimeter of the spinal plate. | 11-12-2015 |
20160157903 | FRACTURE FIXATION SYSTEM INCLUDING LOCKING CAP AND WIRE - A locking cap for a fracture fixation system according to an exemplary aspect of the present disclosure includes, among other things, a cap body that extends along a longitudinal axis between a proximal end and a distal end. An external thread extends around at least a portion of the cap body. A passage extends inside the cap body from the distal end toward the proximal end. An internal thread extends about a periphery of the passage along at least a portion of a length of the passage. | 06-09-2016 |

20110022097 | BONE PLATE SCREW-BLOCKING SYSTEMS AND METHODS - A bone plate screw-blocking system and method that comprises a plate with at least two bone screw receiving holes, blocking elements, bone screws, and a tool capable of simultaneously actuating at least two blocking elements. The plate includes an upper surface and a lower surface with bone screw receiving holes that extend through both surfaces of the plate. The bone screws couple the plate to the bone via the bone screw receiving holes. The blocking elements are movably positioned proximate each bone screw receiving hole. In an initial unblocked position, the blocking elements do not cover the bone screw receiving holes. Upon movement into final blocked positions, the blocking elements cover at least a portion of the bone screw receiving holes and preferably extend over at least a portion of the bone screw during use. | 01-27-2011 |
20130041413 | UNIVERSAL LOCKING AND COMPRESSION DEVICE FOR BONE PLATE - A kind of bone plate gimbal lock pressure device. The body of the bone plate ( | 02-14-2013 |
20160135850 | SYSTEM FOR FIXING CERVICAL VERTEBRAE, AN APPARATUS FOR FIXING CERVICAL VERTEBRAE AND A DRIVER USED FOR AN APPARATUS FOR FIXING CERVICAL VERTEBRAE - A fixing apparatus for cervical vertebrae in which in which a fixing plate is made to be in proximity with cervical vertebrae and screws are inserted into the cervical vertebrae through screw holes formed in the fixing plate, includes an opening and closing member that opens and closes the screw holes while being moved between a closing position for covering the screw holes and an opening position for opening the screw hole on the fixing plate. | 05-19-2016 |
