20080275459 | Surgical instrument attachment mechanism - An instrument attachment mechanism is disclosed that is operable to be temporarily, but securely, connected with a surgical device. The attachment mechanism includes a body that has a drive member protruding outwardly from a portion of the body. The drive member includes a plurality of side walls and a passageway running from a bottom surface of the drive member to a predetermined depth in the drive member. At least one slot is located in a respective one of the plurality of side walls that extends through the side wall into the passageway. A biasing member is positioned within the passageway such that a select portion of the biasing member protrudes outwardly from the slot. A surgical device, such as a surgical instrument or implant, may be temporarily connected with the drive member such that the select portions of the biasing member apply force to an inner wall of a drive receiving member of the surgical device. | 11-06-2008 |
20110106174 | Direct Control Spinal Implant - A bone anchor assembly is provided, which may be used in cervical, thoracic, lumbar or sacral areas of the spine or other orthopedic locations. The anchor assembly includes a bone anchor, a receiver mounted to the bone anchor, a saddle within the receiver, a spacer within the receiver, and an engaging member. The receiver extends along a central longitudinal axis proximally away from the bone anchor. A rod or other elongated connecting element is received in a passage of the receiver in contact with the saddle, and the engaging member engages the connecting element against the saddle, which engages the saddle against the spacer, which in turn engages the proximal head of the bone anchor in the receiver. The orientation of the saddle in the receiver is adjustable to correspond to the orientation of the connecting element relative to the central longitudinal axis of the receiver. | 05-05-2011 |
20110106181 | ADJUSTABLE SADDLE FOR A BONE ANCHOR - A bone anchor is provided, which may be used in cervical, thoracic, lumbar or sacral areas of the spine or other orthopedic locations. The anchor includes an anchoring portion, a receiving portion, and an internal saddle that is rotatable with respect to the receiving portion at least to a degree. The anchoring portion is attachable to a bone. A rod or other elongated support member is received in the receiving portion in contact with the saddle. The rod and saddle may be rotated for variability substantially in a plane, and an engaging member is engaged to the receiving portion to lock the rod within the receiving portion. | 05-05-2011 |
20110184416 | PRE-ASSEMBLED CONSTRUCT FOR INSERTION INTO A PATIENT - Surgical constructs pre-assembled for insertion as a unit into a patient. The pre-assembled construct may include an elongated member with opposing first and second ends. The construct may also include a connector with a body, a first receptacle that extends through the body and receives the elongated member, a threaded aperture that extends from an exterior of the body into the first receptacle, a fastener threaded into the threaded aperture, and a second receptacle that receives a structural member in the patient. The first receptacle may be larger than the elongated member for the connector to be movable along the elongated member. The construct may also include retaining members permanently attached to each of the first and second ends of the elongated member. The retaining members may include a central opening with an inner radial surface that contacts the elongated member and an outer radial surface that extends outward beyond the elongated member. The retaining members may be larger than the first receptacle to prevent the connector from detaching from the elongated member. | 07-28-2011 |
20110196425 | Connector and Method - Embodiments of the invention include a device and method for securing linear elements relative to one another. In some embodiments, medical implant linear elements are secured in a connector by forcing one or both of the linear elements against at least another member such as a tapered member or wedge. The secured linear elements may include rods, posts, screws, hooks, bars, bolts, or other members. | 08-11-2011 |
20110257690 | Transverse and Sagittal Adjusting Screw - A bone anchor assembly is provided, which may be used in cervical, thoracic, lumbar or sacral areas of the spine or other orthopedic locations. The anchor assembly includes a bone anchor, a receiver mounted to the bone anchor, a saddle within the receiver, a spacer within the receiver, and an engaging member. The receiver extends along a central longitudinal axis proximally away from the bone anchor. A rod or other elongated connecting element is received in a passage of the receiver in contact with the saddle, and the engaging member engages the connecting element against the saddle, which engages the saddle against the spacer, which in turn engages the proximal head of the bone anchor in the receiver. The orientation of the saddle in the receiver is adjustable to correspond to the orientation of the connecting element relative to the central longitudinal axis of the receiver. | 10-20-2011 |
20120116464 | MULTI-THREAD BONE SCREW AND METHOD - A bone screw comprises a threaded shank including a distal end portion and a proximal end portion, and defining a first threaded section extending from the distal end portion toward the proximal end portion and adapted for anchoring in cancellous bone. A second threaded section extends contiguously from the first threaded section toward the proximal end portion The second threaded section has a finer thread pattern relative to the first threaded section. In one embodiment, the first threaded section includes a first helical threading defining a single lead thread pattern for anchoring in cancellous bone, and the second threaded section includes a second helical threading interleaved with the first threading to define a duel lead thread pattern for engagement in cortical bone. In a further embodiment, the bone screw includes a head portion extending from the threaded shank and configured for coupling to a spinal implant. | 05-10-2012 |
20150105833 | SURGICAL INSTRUMENT ADAPTOR - A surgical instrument adaptor comprises a member that defines a longitudinal axis. The member is configured for connection to an image guide that is configured to generate a signal representative of a position of a surgical instrument. The member extends between a first end and a second end. The first end includes a first mating part configured for releasable engagement with a mating part of an actuator. The second end includes a second mating part configured for releasable engagement with a mating part of the surgical instrument. Systems and methods are described. | 04-16-2015 |
