    • A mobile bearing knee prosthesis enables a surgeon to convert a mobile bearing insert having articular surfaces, supported by a tibial base plate or tray from a rotating and translating prosthesis to one that rotates only. This conversion is accomplished with a fastener or locking member that connects through an opening in the insert to the tibial base plate. This prosthesis can be used as part of a total knee surgery when the surgeon chooses to use a prosthesis that incorporates a movable articular surface. In one embodiment, a projecting portion extends proximally from the insert and cooperates with a cam on the femoral component. The projecting portion can be a post extending up from the proximal surface of the insert and the femoral component includes an intercondylar surface that may contact the post to constrain the relative motion between the femoral component and the insert. In another embodiment, the insert is a two part assembly that includes a larger member with a central opening and a smaller member that fits the opening.
    • 移动轴承膝关节假体使得外科医生能够将具有由胫骨基板或托盘支撑的关节表面的移动轴承插入件从旋转和平移假体转换成仅旋转的假体。 这种转换是通过将插入物中的开口连接到胫骨基板上的紧固件或锁定构件实现的。 当外科医生选择使用包含可动关节表面的假体时,该假体可用作全膝关节手术的一部分。 在一个实施例中,突出部分从插入件向近侧延伸并与股骨部件上的凸轮配合。 突出部分可以是从插入件的近侧表面向上延伸的柱,并且股骨部件包括可以接触柱的髁间表面,以限制股骨部件和插入物之间的相对运动。 在另一个实施例中,插入件是两部分组件,其包括具有中心开口的较大构件和适合开口的较小构件。

    • A locknutless conduit connector provides for the retentive termination of an electrical conduit to a junction box. The connector includes a connector housing having a conduit receiving end, an opposed conductor egressing end and a central conduit passage therebetween. The conduit passage is defined by opposing connector halves which are relatively movable with respect to one another in clam-shell fashion and which include male and female cooperating engagement members positioned to prevent relative axial movement between the connector halves when the connector is subjected to bending forces.
    • 无锁螺母导管连接器用于将电导管的保持性端接到接线盒。 连接器包括具有导管接收端的连接器壳体,相对的导体出口端和它们之间的中心导管通道。 导管通道由相对的连接器半部限定,相对的连接器半部可以相对于彼此以蛤壳式的方式相对移动,并且包括阳和阴配合接合构件,其定位成当连接器经受弯曲力时,防止连接器半部之间的相对轴向移动 。
