Abstract: A plate insertion apparatus includes a shaft, a distal tip, a driver, and an actuator. The shaft has a proximal end and a distal end and extends along a first axis. The distal tip extends from the distal end of the shaft along a second axis. The distal tip includes a first claw, a second claw, and a space between the first and second claws. The second axis is different than the first axis. The driver is positioned within the space of the distal tip and is biased by a spring extending along the second axis. The actuator is adjacent to the proximal end, wherein actuation of the actuator in a first direction causes the first and second claws to expand and actuation of the actuator in a second direction causes the first and second claws to contract.

Abstract: An awl including a shaft, a housing at least partially encompassing the shaft, a spring within the housing, and a slider coupled with the shaft and the housing. The shaft having a distal end, a proximal end, and a bone engaging tip at the distal end. The housing having a distal end, a proximal end, and a plurality of first engagement members adjacent to the proximal end, wherein the shaft is slidable within the housing. The spring is configured to bias the shaft with respect to the housing. The slider includes a second engagement member in engagement with at least one of the first engagement members. The movement of the slider with respect to the housing causes the second engagement member to engage another of the first engagement members and movement of the shaft with respect to the housing.

Abstract: An intervertebral implant includes a chassis and endplates movable relative to the chassis. The endplates are each movable between a contracted position, wherein the endplates are nearer to a central axis defined relative to the chassis, and an expanded position, wherein the endplates are farther from the central axis. The chassis includes at least one wedge that, in turn, includes surfaces along which the endplates travel in transition between the contracted and expanded positions. The wedge remains stationary relative to the central axis throughout transitions between the contracted and expanded positions.

Abstract: A surgical instrument to implant spinal implants including a shaft, a sleeve, and a handle assembly. The shaft defining a longitudinal axis and having a slotted portion with first slots and second slots. The sleeve rotatably disposed around the slotted portion. The handle assembly pivotably attached to the sleeve by a pivot pin, the handle assembly having a positioning tip sized to be received in the first and second slots of the slotted portion. The handle assembly can pivot about the pivot pin between a first position and a second position. In the first position, the positioning tip engages one of the first slots, while in the second position, the positioning tip engages one of the second slots.

Abstract: An expandable device comprising, a body defining a bore, a shaft received in the bore of the body, an end plate coupled to the shaft, wherein rotation of the shaft translates the end plate with respect to the body, and a locking mechanism engaged with the shaft so as to permit the shaft to rotate in a first direction and apply a resistance force to resist the shaft when attempting to rotate in a second direction.

Abstract: A spinal interbody implant includes a shaft extending along and rotatable about a central axis. The shaft includes a first threaded region. The implant further includes a first link having a first end with first gear teeth. The first end of the first link is fixed at a first point relative to the central axis such that the first gear teeth engage the first threaded region.
