摘要： An integral prosthetic acetabular cup assembly and a method for making the same including an inner liner contacting an outer backing and a plurality of spacers mechanically entrapped between the inner liner and the outer backing. The spacers may be made of a material different from that of the inner liner and of the outer backing.

摘要： An improved modular prosthetic joint has a stem portion embedded in a bone with a removable bearing head frictionally mounted on the stem portion. The bearing head has a bore which mates with a tapered shaft of the stem portion. The bearing head has a generally thin wall defining its continuous and unbroken bearing outer surface, with a wall portion extending directly over the tapered shaft which is thinner than the remainder of the bearing head wall. A puller engages an annular shoulder of the bearing head to pierce through the thinner wall portion of the bearing head, engage the tapered shaft and urge the bearing head away from the tapered shaft. Thus, the bearing head is pierced and removed from its associated stem portion, and second replacement bearing head is then mountable on the tapered shaft by impaction.
摘要翻译：改进的模块化假体关节具有嵌入在骨头中的杆部分，其具有摩擦地安装在杆部分上的可移除的轴承头。轴承头具有与杆部的锥形轴配合的孔。轴承头具有限定其连续且不间断的轴承外表面的大致薄壁，壁部直接延伸在比轴承头壁的其余部分更薄的锥形轴上。拉拔器接合轴承头的环形肩部以穿过轴承头的较薄壁部分，接合锥形轴并将轴承头推离锥形轴。因此，轴承头被刺穿并从其相关联的杆部分移除，然后第二替换轴承头通过冲击安装在锥形轴上。

摘要： Apparatus for positioning a prosthetic acetabular cup within an acetabulum during total hip replacement surgery. The apparatus includes a pusher ball, a pusher arm affixed to the pusher ball, a positioner arm, and a positioner flange affixed to the positioner arm. The apparatus also includes a slot within the flange dimensioned to receive a part of the pusher arm so that the flange can be faced with the pusher ball. The apparatus can affix the flange facing the ball to define a predetermined angle between the pusher arm and the positioner arm. This apparatus also releasably secures the ball generally mated with the acetabular cup, so that the positioner flange and the positioner arm can be released and removed from the remainder of the apparatus while the pusher ball remains within the acetabular cup to maintain uninterrupted pressure on the acetabular cup via the pusher arm.
摘要翻译：用于在全髋关节置换手术期间将假肢髋臼杯定位在髋臼内的装置。该装置包括推动球，固定到推球的推动臂，定位臂和固定到定位臂的定位器凸缘。该装置还包括在凸缘内的槽，其尺寸适于接收推动臂的一部分，使得凸缘可面对推动球。该装置可以将面向球的凸缘固定在推动臂和定位器臂之间限定预定的角度。该装置还可释放地将球固定在髋臼杯上，使得定位器凸缘和定位器臂能够从设备的其余部分释放并移除，同时推动球保持在髋臼杯内，以保持髋臼上的不间断的压力杯子通过推动臂。

摘要： Devices and methods are provided for surgical lavage including pumping liquid to a bone or other tissue surface with a reciprocating pump mechanism operated by pressurized gas wherein pressurized exhaust gas is further utilized to accelerate the pulsed liquid. A first valve arrangement is provided to bypass the pumping mechanism to direct pressurized gas directly onto the bone/other tissue surface without the presence of liquid from the device. A second valve arrangement is provided for optionally venting at least a portion of the exhaust gas to the atmosphere instead of directing it to the bone/other tissue surface. An additive line delivers additive to the gas bypass line for delivery of the additive to the bone/other tissue surface with the flowing gas stream.
摘要翻译：提供了用于手术灌洗的装置和方法，包括用加压气体操作的往复式泵机构将液体泵送到骨骼或其他组织表面，其中进一步利用加压排气来加速脉冲液体。提供第一阀装置以绕过泵送机构以将加压气体直接引导到骨/其他组织表面上，而不会存在来自装置的液体。提供第二阀装置，用于任选地将排气的至少一部分排放到大气中，而不是将其引导到骨/其他组织表面。添加剂线将添加剂输送到气体旁路管线，用于将流体气体流将添加剂输送到骨骼/其他组织表面。
