Implant assembly and method for use in an internal structure stabilization system

ActiveUS20060036244A1Prevent slidingEffectively locking out the conical freedom of the anchorSuture equipmentsInternal osteosythesisEngineeringHead parts
A stabilization assembly is described that stabilizes bony structures such as vertebrae. The stabilization assembly is partially formed by a poly-axial assembly which includes an anchor connected to a poly axial connector assembly head, where the poly-axial connector-assembly head includes a slide ring mounted in the head and a connector mounted in the slide ring. The slide ring allows the connector to move between an upright and a horizontal position relative to the poly-axial connector-assembly head. In the upright position the connector engages with a drive mechanism on the anchor for inserting the anchor into a pedicle. In the horizontal position the connector can engage a poly-axial connector capturing assembly which is the second piece included in the stabilization assembly. An end of the connector engages with a poly-axial connector-capturing head which is connected another anchor mounted in a second pedicle. Once the connector is captured by the poly-axial connector-capturing assembly, the stabilization system is made rigid by installing locking caps in the poly-axial heads.

Helical reverse angle guide and advancement structure with break-off extensions

A spinal fixation device combines an anchor member with an open receiver, such as a polyaxial bone screw or a hook, with a rotatable closure that operably clamps a spinal fixation rod to the anchor member. The anchor member has spaced apart arms forming a rod receiving channel. The arms have arm extensions or tabs connected to main portions of the arms by weakened regions to enable the extensions to be broken off or separated after the rod is clamped. The closure and inner surfaces of the arms and tabs have mating helical, anti-splay, reverse angle guide and advancement structure formed thereon that mechanically cooperate to prevent splaying of the arms and the extensions as the closure is advanced into the rod receiving channel. The increased length of the arms with the extensions enables the rod to be captured at a greater distance from the seat of the channel and allows the rod to be urged toward the seat by helical advancement of the closure into the channel, starting between the extensions. Separation of the break-off extensions results in an implant with a desirable low profile.

Graphical user interface for building boolean queries and viewing search results

A graphical user interface is for building Boolean queries and viewing search results using search cells, combination cells, a toolbar, and a menu bar. The search cells are movable within a workspace and preferably contain a text field, a facet type designation, an advanced button and a hit count. Search cells can search records by a category, keyword, date or numeric value. Categories are preferably chosen with the assistance of a category walker. The combination cells are movable within the workspace and preferably contain a combine icon, a hit count and an expression field. The combination cell is a Boolean combination of two or more selected search cells. In the preferred embodiment of the invention, the Boolean logic is graphically depicted with the use of combination brackets. The contents of each combination bracket is controllable by the use of movable graphical pins that are located between each pair of search cells. The combination bracket can be represented by use of a rectangular bracket, a square bracket, or a curly brace. In an alternative embodiment of the invention, the Boolean query is depicted in a folder tree hierarchy. Search folders and combination folders are used to depict search cells and combination cells, respectively. Search folders contain the same information as search cells, but search folders can be toggled to appear as small folder icons within the workspace. Combination folders are represented as small folder icons containing a logical AND icon, a logical OR icon or a logical MINUS icon. Search folders are shown to be included within combination folders through the use of the folder tree hierarchy, just as computer files are shown to be included within a folder in a typical file manager program. In the preferred embodiment, the invention runs an internet browser and is coupled to a remote server through the internet. To minimize communication delays across the internet, an applet can be run on the local client to perform most graphical display manipulations prompted by the searches manipulation of the search cells, the combination cells, the toolbar, and the menu. The remote server is used to execute queries received over the internet from the local client and deliver search results back to the local client over the internet. Optionally, the client can take on some or all of the tasks of the server in executing queries over the internet.

A method, apparatus and computer program product are provided for facilitating data entry into an electronic device via a touchscreen. As a user touches the touchscreen at a first location, a cursor may be displayed at that location. Because the cursor, as well as various items displayed on the touchscreen, are likely now obscured by the instrument used to touch the touchscreen, the user may sweep his or her finger away from the first location, at which point a pointer, or similar connection element, may be displayed between the cursor, which is maintained at the first location, and the second, new location of the instrument. The user may unlock the connection element and cursor, causing the connection element, and by extension the cursor, to begin moving with the instrument. The user may then move the cursor to its desired location by movement of the offset connection element.

Method for compensating for angular transmission error of an actuator

The non-linear elastic deformation component included in the angular transmission error of an actuator provided with a wave gear drive is a component of the angular transmission error occurring due to elastic deformation of a flexible externally-toothed gear when the direction of rotation of the motor shaft changes. This component can be analyzed by driving the motor in a sine-wave shape. A model of the non-linear elastic deformation component (non-linear model) obtained from the analysis results is used to store data or a function for compensating for this component in a motor-control device. Compensation for the non-linear elastic deformation component (θHys) is added to a motor-shaft angle command (θ*M) as a compensation input (Nθ*TE) for feed-forward compensation. As a result, the non-linear elastic deformation component (θHys) can be effectively reduced, and the positioning precision of the actuator can be improved.
