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 implantable spinous process fixation device includes an elongated component, top and bottom pivoting wing components, arranged opposite and parallel to the elongated component and separated from it by a spacer. First and second spinous processes of first and second adjacent vertebras are clamped between a top portion of the elongated component and the top pivoting wing and between a bottom portion of the elongated component and the bottom pivoting wing, respectively, by pivoting the top and bottom pivoting wings toward the top and bottom portions of the elongated component. The clamping of the spinous processes stabilizes the positions of the adjacent vertebras and prevents them from moving relative to each other.

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).

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.
