The present disclosure provides for spinal implants deployable between a contracted position and an expanded position. The spinal implant may include a first endplate and a second endplate, each having a plurality of guide walls and inclined ramps. The spinal implant may further include a moving mechanism having first and second trolleys configured to act against the first and second plurality of ramps. The expansion mechanism may further include a first set screw and a second set screw opposite the first set screw. The moving mechanism may be configured to operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws along a rotation axis, and may also operably adjust an angle of inclination between the first and second endplates upon rotating the first set screw or second set screw along the rotation axis.

A method comprises the steps of providing a tool over a collar secured to a stud on a gas turbine engine system. The collet is driven to rotate and remove the collar from the stud. A tool for removing collars from studs has a driver with a housing receiving a piston. A spring drives the piston, and the housing also has a hydraulic fluid supply opening for selectively receiving a hydraulic fluid to move the piston in opposition to a force from the spring. Collet fingers are movable between a released position and a secured position when a supply of hydraulic fluid is supplied into the housing.

A provisional engagement feature for selectively connecting a fastener such as a screw to a driving tool, the fastener incorporating a head with a recess extending therein and a projection contained within the recess for engagement with a corresponding engagement feature and/or selective locking feature of the driving tool.

A screwdriver includes a body extending longitudinally from a proximal end to a distal end. The distal end includes a distal screw engaging tip. The screwdriver also includes a slot extending through a width of the screw engaging tip and extending proximally a distance into the body. The slot permits opposed portions of the screw engaging tip to spread apart from one another into a locking configuration in which the opposed portions apply a radially outward force against an interior surface of a recess in a head of a screw into which the screw engaging tip has been inserted to releasably lock the screw engaging tip within the recess.

An improved implant inserter, and method of using same, with an elongated, substantially rigid shaft having a proximal surface which is capable of receiving a driving force, and a substantially rigid tip portion having a distal end and a proximal end. At least the distal end of the tip portion is capable of being placed within an implant such as a suture anchor. The inserter further includes a compliant region disposed between the tip portion and the shaft which requires less lateral force to bend than the tip portion, at least when the tip portion has been placed within the implant.

An anti-slip fastener remover tool includes a torque-tool body, a plurality of paired engagement features, and an intersection point. The plurality of paired engagement features that grips the lateral surface of the stripped fastener head is radially positioned around a rotation axis of the torque-tool body. The plurality of paired engagement features, wherein each paired engagement feature is offset by 30 degrees, comprises a first engagement feature and a second engagement feature. The first engagement feature and the second engagement feature each comprises a bracing section, a cavity section, and a connector section that are adjacently connected to each other. The cavity section of the first engagement feature is adjacently connected to the cavity section of the second engagement feature. The bracing sections of the first engagement feature and the second engagement feature are oppositely positioned of each other about the cavity sections of the first and second engagement features.

The present invention relates to a driver system and method for engaging an article. During operational use of the driver system the user starts with the alignment of a bit and a cavity of the article, the bit is rotated to move a wedge into an internal wedge slot within the cavity of the article. This engagement of the wedge and the internal wedge slot locks the lateral movement of the bit relative to the article, therein allowing for the bit to stay engaged within the article during rotational or torsional force induced upon the article by the user of the bit.

An anti-slip fastener driver includes a shank and a driving portion formed on an end of the shank and defining a longitudinal axis. The driving portion includes an outer periphery surrounding the longitudinal axis and having a first peripheral face. An end of the driving portion opposite to the shank includes a first end face connected to the first peripheral face. The first end face includes a first side and a first angle located outside of the first side. The end of the driving portion opposite to the shank includes a reference plane perpendicular to the longitudinal axis. The first side is located on the reference plane. An end of the first side is adjacent to the longitudinal axis. Another end of the first side opposite to the longitudinal axis is connected to the first peripheral face. The first angle is located between the reference plane and the shank.
