摘要： A screw extension assembly for use in minimally invasive spinal surgery, the assembly has an inner slotted shaft and an outer shaft, a rod reducer and a removable nut. The combination when assembled is configured to move a spinal fixation rod into a slotted rod receiving spinal implant where it is seated and affixed thereto. The screw extension assembly further has a locking knob rotationally coupled to a proximal end of the outer shaft, wherein the inner shaft has one or more cam grooves and the locking knob has a pin extending into and guided by said cam groove causing the outer shaft to translate longitudinally upon rotation of the locking knob relative to the inner shaft toward an engaged position locking the deflectable legs in the coupled position to the slotted rod receiving implant.

摘要： A modular tulip assembly has a rod receiving tulip and a saddle. The saddle is interlockingly held inside a distal portion of the tulip. The saddle has an external locking groove or recess. The tulip has a locking projection. The locking projection is positioned into the external locking groove or recess and holds the saddle in a pre-loaded unlocked state ready to be pushed onto a head of an implanted bone screw. Upon receiving the head of the bone screw, the saddle can be moved distally relative to the tulip to a locked state by moving the locking groove or recess distally past the locking projection to where the proximal end of the saddle is past abutting the locking projection.

摘要： A detachable vertical cutter for insertion into a cylinder or tube is formed as a single unitary structure. The single blade has a pair of tool attachment end portions and a cutting blade extending in a loop between the attachment ends. The cutting blade is inclined vertically relative to a longitudinal axis of a cylinder or tube into which the attachment ends can slide into. The cutting blade has a cutting edge, a portion of which when extended free of the cylinder or tube will extend a distance greater than the tube outside diameter. The cutting edge when pushed inwardly and pulled outwardly between adjacent vertebrae scrapes and cuts disc material. When retracted the cutting blade deflects into the cylinder or tube for insertion or extraction into or from the disc space.

摘要： A bone anchor locking device for receiving a bone anchor having a shank and an enlarged head, the device has a bone anchor, a dome and a conical split washer. The receiving portion has a base extending radially outward and inwardly to a wall. The dome has a center aperture sized to pass a bone anchor. The split washer has an inner conical surface sloped to slide and expand against at least a portion of the base on insertion of a bone anchor to allow a maximum diameter of a head of a bone anchor to pass and thereafter the split washer retracts overlying the maximum diameter of the head to prevent a bone anchor from backing out.

摘要： A modular head pedicle screw assembly has a bone screw, a tulip, a locking split ring and a saddle. The locking split ring is internal of the tulip positioned in a recess of an inner surface of the tulip. The saddle has a proximal end for engaging a rod and a distal end for receiving the bone screw. The saddle has an exterior surface positioned between the ends. The outer surface is sized to move axially inside the tulip. The saddle expands the locking split ring in an initial pre-loaded position and upon insertion of the tulip over the bone screw, the saddle moves proximally disengaging the locking split ring simultaneously causing the locking split ring to relax to an unexpanded condition while providing tactile and audible feedback to the surgeon and locking the bone screw into the tulip.

摘要： An expandable implant device (100, 300, 600) for insertion between two vertebrae (400) is disclosed. The device (100, 300, 600) has a center body (10) one or more lift bodies (20, 40) and an external retaining band (60). The external retaining band (60) holds the sides (22, 42) of the one or more lift bodies (20, 40). The center body (10) has ramp surfaces (11) having a plurality or sets of ramps (11) sloped for allowing upward movement of the one or more lift bodies (20, 40). The sides (22, 42) have complimentary ramp surfaces that fit onto the ramps (11) of the center body (10). The height of the device (100, 300, 600) is increased by upward movement or downward movement or both of the one or more lift bodies (20, 40) driven by the lengthwise movement of the center body (10).

摘要： A modular head bone screw assembly has a bone screw, a tulip and a saddle. The saddle is positioned in a recess inside of the tulip. The saddle has a proximal end for engaging a rod and a distal end for receiving a hemispherical or at least partial hemispherical head of the bone screw. The saddle is sized to move axially inside the tulip. The saddle has a plurality of fingers separated by slots extending from near the proximal end through the distal end in an initial un-loaded position and upon insertion of the tulip over the head of the bone screw, the saddle moves proximally over the head simultaneously causing the fingers to move past a maximum diameter of the hemispherical head and upon tightening the rod by a set screw, the fingers locking the bone screw into the tulip.

摘要： A modular head-to-head cross connector or construct extension system comprising a fastener element driven into a bone in a first orientation, a first U-shaped body operable to receive the fastener element and operable to receive a first rod in a first rod receiving channel, and a first compression element driven adjacent to and against the first rod in the first rod receiving channel, thereby engaging the first rod against the fastener element in a second orientation independent of the first orientation of the fastener element. The system further comprises a second U-shaped body operable to receive first compression element and operable to receive a second rod in a second rod receiving channel, and a second compression element driven adjacent to and against the second rod in the second rod receiving channel, thereby engaging the second rod against the first compression element in a third orientation independent of the second orientation.

摘要： An improved joint fusion screw for transiliac fixation has an elongate hollow shaft. The hollow shaft has an externally threaded end portion extending to a tip end and a non-externally threaded shank portion having openings. The tip end has at least two bone cutting flutes at the bottom of the shaft. Each bone cutting flute has a cutting edge on a circumferential exterior of the threaded tip to cut bone and direct the cut bone internally into the hollow shaft toward the shank.
