摘要:
A modular long bone prosthesis is provided having a proximal component and a retroversion component. The proximal component is configured at a proximal end to receive a head forming a portion of a joint and is formed at a distal end to mate with additional prosthesis components. The proximal component is formed to simulate an angle inherent in the proximal end of the bone to be replaced and includes an indicator adjacent the distal end to facilitate rotational alignment of the proximal component and additional prosthesis components. The retroversion component includes a proximal end configured to mate with the distal end of the proximal component. The proximal end includes alignment indicia for positioning relative to the indicator on the proximal component. When the indicator is in a first position relative to the alignment indicia the proximal component and the retroversion component establish a first alignment orientation forming an angle simulating the angle inherent in the proximal end of the right long bone of the long bone to be replaced. When the indicator is in a second position relative to the alignment indicia the proximal component and the retroversion component establish a second alignment orientation forming an angle simulating the angle inherent in the proximal end of the left long bone of the long bone to be replaced.
摘要:
A shearable fastener has a threaded shank adapted for engagement with a threaded bore and a head portion formed for engagement with a drive tool, the shank being formed with a series of axially separated weakenings defining a series of shear planes. The weakenings are formed such that the applied torque necessary to cause the shank to shear increases progressively from the shear plane furthest from the head portion to the shear plane nearest the head portion. The weakenings are holes, grooves or slits formed in the shank and the radius at the bottom of the holes, grooves or slits is varied to produce or contribute to the increase in shear torque.

Insulation-piercing fasteners are provided having a generally cylindrical shank, externally threaded along at least part of its length. The end portion of the shank is configure to engage an insulated electrical conductor and is formed with a hollowed end portion. The hollowed end portion has a generally cylindrical recess having a diameter less than the diameter of the shank. The wall of the hollowed end portion has at least one interruption. The width of the interruption is less than the maximum internal width of the hollowed end portion.

摘要:
An electrical connector has a connector body including a socket for an electrical conductor, the connector body having an electrically insulating shroud and having a threaded bore in which a connecting bolt is threadedly engaged. The connecting bolt is capable of actuation into engagement with a conductor inserted into the socket by providing a drive member engaged with the connecting bolt and extending through an opening in the insulating shroud to a rotatable, electrically insulating cap. The connecting bolt is slidably mounted on the drive member, the drive member being adapted to shear at a position between the opening in the insulating shroud and the point of engagement of the drive member with the connecting bolt when a predetermined torue is applied to the drive member, such that the cap and a residual portion of the drive member attached thereto can be withdrawn from the opening in the insulating shroud. The opening in the insulating shroud is adapted substantially to close after the drive member has so sheared and been withdrawn.
摘要:
There are disclosed embodiments of screws for use in orthopedic surgery, particularly in pediatric patients. In some embodiments, inner and outer implantable members are provided, with the outer implantable member threadable on the inner implantable member to provide compression on two or more bone parts. In some embodiments, screw members are provided with a threaded shaft, and the thread continues into the head of the screw member to enable the thread to remain in pediatric bone.

摘要:
An electrical connector comprising a connector body defining a socket for receiving an electrical conductor, a fastener mounted within the socket and engaged with a thread of an internal surface of the connector body so that rotation of the fastener relative to the connector body along a longitudinal axis of the socket causes movement of the fastener between a first position in which the socket is able to receive the electrical conductor and a second position in which the fastener fastens the electrical conductor within the socket, and a drive component rotatably mounted to the connector body and configured to engage the fastener such that rotation of the drive component with respect to the connector body causes rotation movement of the fastener between the first position and the second position is disclosed.
摘要:
According to the invention, systems, and methods are disclosed for testing of a first program is provided. First, an input file containing a location of a first program, identifiers of other programs to be invoked by the first program, and arguments to be passed to the other programs is read. Next, the first program is executed including invoking the other programs and passing to those programs the arguments specified. Finally, log files are generated based on results of execution of the first program and the other programs.
摘要:
A method of facilitating an outbound customer interaction involves monitoring user access activity, and automatically accumulating access data concerning such user access activity, with respect to a resource retrieved from one or more network locations (e.g., identified by URLs). The user access to the one or more network locations typically occurs via a user device coupled to a network to facilitate the access to the network locations. A trigger event is then detected based on the user access activity as reflected by the accumulated access data.
