摘要： A polyaxial screwdriver for inserting a bone screw in a vertebra. A polyaxial bone screw assembly includes a coupling element. When a screw engaging end of the polyaxial screwdriver is lowered on the head of the bone screw, the complimentary surfaces of the screw engaging end of the screwdriver and the head of the screw self-align. A ratchet mechanism formed in the screwdriver provides progressive and automatic locking of the polyaxial screwdriver to the coupling element and prevents the accidental unthreading from the coupling element. In another embodiment of the polyaxial screwdriver, a collet slides over the outside surface of the upper end of the coupling element and locks on to the coupling element. In yet another embodiment of a polyaxial screwdriver, the outer sleeve of the polyaxial screwdriver has a split end that securely engages the coupling element.

摘要： An insertion instrument is configured to eject at least one anchor body into respective target locations, and subsequently apply a predetermined tensile force at least one actuation member of the at least one anchor member so as to actuate the at least one anchor body from a first configuration to a second expanded configuration. The insertion instrument can include a tension assembly that applies the predetermined tensile force to the at least one actuation member. The predetermined tensile force can be defined by a distance of travel, a predetermined failure force of a fuse, or a combination of distance of travel and a predetermined failure force of a fuse.

摘要： A bone screw assembly includes a tulip-shaped seat, a bone fixation device, a ring-shaped washer, a rod and a cap. The tulip-shaped seat comprises a through opening dimensioned to receive the bone fixation device and a horizontal channel dimensioned to receive the rod. The washer is placed into the seat on top of the bone fixation device head and comprises first and second side tabs and a first pair of upward extending projections separated by a first gap and a second pair of upward extending projections separated by a second gap. The side tabs interface with a groove formed in the bottom portion of the seat. The rod is placed within the channel and positioned within a groove formed on the top surface of the washer. The cap includes first and second projections extending downward from its bottom surface and each of the first and second downward projections comprises first and second sidewise extending ridges. The first ridges of the first and second projections are aligned and placed within the first and second gaps of the washer, respectively, and interface with a first groove formed on the side portion of the seat and the second ridges interface with a second groove on the side portion of the seat when the cap is rotate.

摘要： A bone screw driver (12) for inserting a bone screw (14) into a bone region (218A) includes a driver shaft (12B) that selectively engages the bone screw (14). The bone screw (14) includes a screw threaded region (14A) and a screw engagement region (14B). The screw engagement region (14B) includes a screw shaft (14D) and an engager ring (14E). The driver shaft (12B) includes a shaft aperture (322), a first resilient member (324A), and a first shaft projection (326A). The shaft aperture (322) receives at least a portion of the screw shaft (14D), the first resilient member (324A) engages the screw shaft (14D) to inhibit movement of the screw shaft (14D), and the first shaft projection (326A) engages the engager ring (14E) so that rotation of the driver shaft (12B) results in rotation of the bone screw (14). With this design, in certain embodiments, the bone screw (14) can be removed with the bone screw driver (12) from a screw retainer (16) that retains the bone screw (14), and inserted into the bone region (218A) without the physician contacting with the bone screw (14). This reduces the likelihood of contaminating the bone screw (14) and increases the likelihood of success for the procedure.

摘要： A bone staple (10) for securing a first bone region (12A) to a second bone region (12B) includes a staple body (16) having a first leg section (18), a second leg section (20), and a connector section (22). The first leg section (18) is insertable into the first bone region (12A). The second leg section (20) is insertable into the second bone region (12B). The connector section (22) connects the first leg section (18) to the second leg section (20). The connector section (22) includes a deformable region (22A) that is movable from a first configuration (14A) in which the leg sections (18) (20) are spaced apart a first distance (24) and a second configuration (14B) in which the leg sections (18) (20) are spaced apart a second distance (26) that is less than the first distance (24). In one embodiment, compression of the deformable region (22A) causes the deformable region (22A) to move from the first configuration (14A) to the second configuration (14B). As a result of this design, the bone staple (10) can easily be moved from the first configuration (14A) to the second configuration (14B). The deformable region (22A) can be substantially square ring shaped and can define a region aperture (22D) that is substantially square in the first configuration (14A). Further, the deformable region (22A) can be substantially oval ring shaped and the region aperture (22D) can be generally rectangular shaped in the second configuration (14B).
