A modular anterior lumbar interbody fusion device comprises a monolithic interbody fusion cage and a modular plate resiliently attached thereto. The cage includes an open architecture with top and bottom cross members and a pair of opposing arms projecting from respective side structures of the cage to define a pocket at the cage anterior end. The modular plate is received in the pocket and attached to the cage by resilient latches. The plate lies fully within the profile of the cage with the resilient latches lying fully within the thickness of the plate. The plate provides a structure to close the anterior portion of the modular cage after introduction of bone graft material while allowing for use with integrated fixation. Attachment features between the monolithic cage and modular plate are universal allowing for selection of various modular device configurations with minimal components.

An ultrasonic surgical device capable of cutting biological tissues such as bone and cartilage. The ultrasonic surgical device includes a static casing, which sheaths an ultrasonic horn, and a lubrication film, which separates the ultrasonic horn and the static casing. The static casing, which may also incorporate a plurality of fluid channels to allow passage of fluids along its length and eventual distribution of such fluids at the cutting end and biological tissue interface, inhibits the transfer of heat generated along the ultrasonic horn. The cutting end and the static casing are separated by a flexible joint, which serves to inhibit the transfer of vibrational energy, and consequently heat, from the cutting end to the static casing. As such, the static casing remains stable and can be used both to manipulate the surgical device with greater haptic control and facilitate effective penetration of larger cross-sections of biological tissue.

An expandable sizer instrument for distracting and spacing opposing vertebral bodies of a spine comprises an elongate hollow shaft defining a longitudinal axis and having opposed distal and proximal ends. An actuator is provided at the proximal end and an expandable distractor is provided at the distal end. An elongate push rod extends within the shaft, a proximal end of the push rod being coupled to the actuator and a distal end being coupled to the expandable distractor. The distractor comprises a lower plate immovably attached to the shaft, and an upper plate coupled to the lower plate by a linkage mechanism fully contained within the perimeter of the distractor and operable to move the upper plate away from the lower plate in an expansion direction substantially parallel to the lower plate. The linkage mechanism comprises two laterally spaced linkage pairs with a middle link disposed therebetween.
