    摘要： A spinal retractor for use in lumbar or dorsal laminectomies or spinal fusions, and for microscopic lumbar laminectomies, which comprises a pair of parallel arms and a corresponding pair of toothed blades which are slidably received on the arms, the blades being forced apart from one another by the arms under the control of a rack and pinion mechanism. The blades are constructed so that their teeth and configuration serve to hold the lumbar musculature when they are forced apart and adequately to expose the facets, and the blades are also configured so that they will not slip out of the wound as they are spread apart by the retractor arms.

    摘要： There is disclosed an improved fastener and driver assembly which assures sufficient depth of engagement between the drive socket of the fastener and the working portion of the driver bit to provide efficient torque transfer from the driver to the fastener. The assembly includes a fastener having a recessed drive socket which is multi-lobular in cross-section, having an inner surface formed by alternating and smoothly joined flutes and lobes. The assembly also includes a driver for imparting rotational torque to the fastener which includes a head portion having a tip end and a center axis. The head portion of the driver is correspondingly multi-lobular in cross-section. The flutes are formed generally parallel to the center axis of the driver while the lobes of the head portion are tapered axially, converging toward the tip end of the head portion. This arrangement enables the driver head to enter the fastener socket to a predetermined depth, without binding, to thereby insure sufficient depth of engagement between the fastener lobes and the driver flutes to provide efficient torque transfer from the driver to the fastener.

    摘要翻译： 公开了一种改进的紧固件和驱动器组件，其确保紧固件的驱动插座和驱动器钻头的工作部分之间的足够的接合深度，以提供从驾驶员到紧固件的有效的扭矩传递。 该组件包括具有凹入的驱动插座的紧固件，所述凹入的驱动插座的横截面为多小叶片，具有通过交替且平滑地连接的凹槽和凸角形成的内表面。 组件还包括用于向紧固件施加旋转扭矩的驱动器，其包括具有尖端和中心轴线的头部。 驱动器的头部横截面相应为多小叶。 凹槽大致平行于驱动器的中心轴线形成，而头部的凸角轴向呈锥形，朝头部的顶端会聚。 这种布置使得驾驶员头部能够在没有装订的情况下进入紧固件插座到预定的深度，从而确保紧固件凸角和驱动器凹槽之间的足够的接合深度，以提供从驾驶员到紧固件的有效的扭矩传递。

    摘要： A compression screw for applying compression at a bone joint. The compression screw includes an axial screw body extending from a distal end to a proximal end with the distal end including a series of bone engaging threads configured to be self-drilling and self-tapping and the proximal end including a head which defines a radially extending shoulder. At least one proximal rotary cutting structure is defined proximally of the bone engaging threads. The at least one proximal rotary cutting structure is configured to be self-drilling such that a proximal portion of the axial screw body cuts into and advances within a bone of the bone joint as the axial screw body is advanced. A method of inserting the compression screw is also provided.

    摘要： The present invention relates to a clamping screw (6) for osteosynthesis, comprising at least one screw thread (7, 10) along a main axis (X) and, at its end referred to as the apex end (11), having a socket (12) which, about said main axis (A), has evenly angularly distributed shapes designed to accept complementing shapes of a screwdriver (19) engaged in said socket (12), notable in that the socket (12) of the screw (6) comprises at least three regular shapes (13) of which the vertices are inscribed inside a circle referred to as circumscribed circle (30) and at least two adjacent vertices of the socket (21) are connected to form a convex lobe referred to as indexing lobe (16) of which the radius of curvature is equal to the radius of the circumscribed circle (30).

    摘要： A twist-drivable pin assembly includes first and second drivers, each having a driving end which can be received in a bore in the end of a twist-drivable pin, and an opposite end at which torque can be applied. The cross-sectional shape of each of the drivers at its driving end has a first plurality of apexes whose relative locations coincide with the apexes of a regular polygon such as a hexagon. The drivers differ from one another in their cross-sectional shapes at the driving end by virtue of one or more faces of at least one of the drivers between adjacent pairs of apexes having a groove formed in it. Each of first and second twist-drivable pins has a bore extending into it which is defined by a second plurality of apexes arranged as a regular polygon such as a hexagon and which is open at one end.
