    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 clamp assembly (16) for stabilizing one or more adjacent regions (12A) (12B) and for selecting a bone screw (18) to be inserted into the one or more adjacent regions (12A) (12B) includes a first clamp side (224), a second clamp side (226) and a connector (228) that pivotally secures the first clamp side (224) and the second clamp side (226) together. The first clamp side (224) includes a first locking component (236) having a first plurality of first teeth (236B) and the second clamp side (226) includes a second locking component (244) having a second plurality of second teeth (244B). The plurality of first teeth (236B) selectively engage the plurality of second teeth (244B) when the clamp assembly (16) is positioned about the bone regions (12A) (12B) so that the clamp assembly (14) is in a locked position with the first clamp side (224) and the second clamp side (226) engaging substantially opposite sides of the adjacent regions (12A) (12B). Additionally, the clamp assembly (16) includes a screw guide (20) that is secured to at least one of the clamp sides (224) (226). The screw guide (20) provides information for selecting the appropriate bone screw (18) based on the relative position of the clamp sides (224) (226).

    摘要: A snap-off screw (10) for insertion into one or more two bone regions (12A) (12B) includes a screw body (14) having a screw region (16) and a driver region (18). Upon insertion of the screw region (16), the driver region (18) is designed to be decoupled from the screw region (16). The screw region (16) includes a screw distal end (224), an opposed screw proximal end (226), a threaded area (228), and a head area (232) positioned at the screw proximal end (226). The driver region (18) includes a driver attachment end (238) and an opposed driver distal end (240). The driver attachment end (238) is coupled to the screw region (16) between the screw distal end (224) and the screw proximal end (226). With this design, when the driver region (18) is decoupled from the screw region (16), a screw break surface (460) is positioned below a portion of the head area (232) of the screw region (16). As a result thereof, the screw break surface (460) does not provide an area of irritation for soft tissue around the inserted snap-off screw (10).

    摘要: An insertion tool for a rotor blade anchor. The anchor is pivotably coupled to a handle so that the anchor can assume a first position in alignment with the longitudinal axis of the handle. The tool is designed to be rotated about the longitudinal axis so that the anchor, when placed in a bore hole in biological tissue, can attain a second position substantially perpendicular to the longitudinal axis. The anchor itself includes a cutting surface thereon. A deploy spring is disposed on the handle and biases the anchor toward the second position. In use, when the rotor blade is inserted into an object such as a bone, the object moves the anchor toward alignment with the longitudinal axis. When the anchor is inserted far enough into the object, a user rotates the handle and the anchor. The deploy spring biases the cutting surface so that is engages with the sidewall of the borehole. The rotation of the handle causes the cutting surface to cut into the object. The rotation imparted by the user and the biasing produced by the deploy spring causes the anchor to undergo a screwing type motion as it is being inserted into the object. Eventually the anchor attains a position substantially perpendicular to the longitudinal axis.
