摘要： A visco-elastic motion-limiting artificial intervertebral disc prosthesis is provided that mimics the physiologic function of a normal spinal disc. The disc comprises upper and lower endplates having therewithin channels or openings for optionally receiving one or more motion-limiting members fitted on each end with an enlarged portion. One or more compression stops is provided between the upper and lower endplates. Additionally, an elastomeric cushion is disposed between the endplates and surrounds the motion-limiting members. Also, force transducers and microelectronics can be utilized to provide data to the surgeon or the patient regarding the load state of the disc.

摘要： A locking screw assembly is provided which allows installation into a plate-like member using relatively little force, but which requires relatively great force for removal. The fastener has an annular locking ring provided within a groove in the head of the screw to allow the screw to sit within or flush with the anterior surface of the plate. The through-hole in the plate which receives the locking screw comprises an entrance, a collar section, an undercut, and an exit. The locking ring resides within the undercut. The locking ring has a leading surface that is chamfered or radiused and a trailing surface that is flat. The chamfer allows the locking ring to easily be inserted into the through-hole by interacting with a lead chamfer in the entrance. After installation, the flat trailing surface abuts a lip adjoining the collar section and the undercut and prevents the screw from being easily removed from the through-hole.

摘要： An adjustable limb support system is provided for an operating room table to adjustably orient and position a stirrup or boot. The support system provides an adjustable support in combination with a vertically adjustable support. The vertically adjustable support includes a support arm, a ratchet wheel, a lock pin, and a ratchet release. The support arm is connected to a housing which both rotate about the ratchet wheel in a rotational plane extending upwardly and outwardly from the operating room table for automatic abduction. The lock pin engages the ratchet wheel and allows the support arm to be rotated upwardly but not downwardly. The ratchet release disengages the lock pin and allows the support to be rotated downwardly. The support arm can thus ratchet upwardly to fixed vertical positions and be lowered only by disengaging the lock pin. The adjustable support includes a retaining block, a compression block, and a compression head. The retaining block defines a passage for receiving a connecting rod secured to the stirrup or boot. The compression block defines a passage for receiving the support arm of the vertical adjustable support. The compression head when tightened prevents translation and rotation of the compression block on the support arm, and rotation of the compression block and the retaining block relative to each other. When the compression head is untightened the compression block can be translated or rotated on the support arm, and the blocks can be rotated relative to each other, in order to orient and position the stirrup or boot. The stirrup or boot freely rotates or swings about the axis of the connecting rod at all times.
摘要翻译： 为操作室台提供了一个可调节的肢体支撑系统，以便可调整地定向和定位蹬或开启。 支撑系统提供可调节的支撑件与可垂直调节的支撑件的组合。 可垂直调节的支撑件包括支撑臂，棘轮，锁定销和棘轮释放。 支撑臂连接到壳体，壳体围绕棘轮旋转，该旋转平面从手术室台面向上和向外延伸，用于自动外展。 锁定销接合棘轮并允许支撑臂向上旋转但不向下旋转。 棘轮释放使锁定销脱离并允许支撑件向下旋转。 因此，支撑臂可以向上棘轮到固定的垂直位置，并且仅通过使锁定销脱离而降低。 可调节支撑件包括保持块，压缩块和压缩头。 保持块限定了用于接收固定到马镫或靴子上的连杆的通道。 压缩块限定用于接收垂直可调节支撑件的支撑臂的通道。 压缩头在紧固时防止压缩块在支撑臂上的平移和旋转，以及压缩块和保持块相对于彼此的旋转。 当压缩头未拧紧时，压缩块可以在支撑臂上平移或旋转，并且块可以相对于彼此旋转，以便定位和定位马镫或靴子。 马镫或靴子始终围绕连杆的轴线自由旋转或摆动。

摘要： A locking screw assembly is provided which allows installation into a plate-like member using relatively little force, but which requires relatively great force for removal. The fastener has an annular locking ring provided within a groove in the head of the screw to allow the screw to sit within or flush with the anterior surface of the plate. The through-hole in the plate which receives the locking screw comprises a ledge and an undercut. When the fastener is installed into the plate, the locking ring resides within the undercut and is prevented from backing out by the ledge. The locking ring has a leading surface that may be chamfered or radiused and a trailing surface that may be flat. The chamfer allows the locking ring to easily be inserted into the through-hole by interacting with the through-hole. After installation, the trailing surface contacts the ledge.

摘要： An apparatus (10) for supporting a patient during a medical procedure includes a bead bag (18) that is filled with compressible beads (20) and that forms a lower layer of the apparatus (10). The apparatus (10) also includes a layer of foam material (30) that is located above the bead bag and an air cell grid (36) that has a plurality of inflatable air cells (38). The air cell grid (36) forms an upper layer of the apparatus (10) and provides a soft surface upon which the patient lies. The bead bag (18), when subjected to a vacuum, becomes rigid for supporting the air cell grid (36) against the patient for helping to maximize a surface area of contact between the patient and the apparatus (10).
