摘要： 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.

摘要： A connector provides for the termination of a first electrical cable and a second electrical cable where each cable includes a plurality of conductors extending through an outer jacket. The first cable has a diameter which is larger than the second cable. An elongate gland body includes a cable receiving end, a conductor egressing end and a longitudinal center bore therethrough for receipt of the first and second cables individually. A gland nut is positioned in axial alignment with the gland body and is attachable thereto. First and second resilient sealing members are positioned between the gland body and gland nut and are resiliently deformable for effecting a cable seal. A portion of first sealing member is resiliently deformable through an opening in the gland nut and the second sealing member is urged into frictional engagement with the first sealing member upon termination of the second cable in the connector. An insert member is also provided which is positionable within the conductor egressing end of the gland body so as to accommodate and precisely locate the second cable in the connector.

摘要： An impactor apparatus and method for assembling modular orthopedic prosthesis parts includes a base member that can be for example an instrument from a tray or an instrument tray lid. The base member defines a plane and provides a plurality of components extending away from the plane. The tray components include a pair of spaced apart supports. An impactor tool can be removably supported upon the supports in a fixed position relative to the base member, preferably generally parallel thereto. The components include an impact driver tool actuator that pivotally attaches to the base member. A pair of prosthesis parts or components are connectable at a taper lock connection defined by respective tapered annular portions of the prosthesis parts. The components and impact driver tool support the prosthesis parts adjacent the base and axial alignment with the impact driver tool, the prosthesis parts being generally positioned in between the pair of spaced apart supports. The impact driver tool provides an actuator for activating the driver to transmit a load to the prosthesis parts for driving the parts together at the taper lock connection. The spaced apart supports of the base hold opposite end portions of the assembly of the prosthesis and impact driver in fixed relation to the base member.
摘要翻译：用于组装模块化矫形假体部件的冲击器装置和方法包括可以是例如来自托盘或器械托盘盖的器械的基座构件。基座构件限定了一个平面并且提供了远离该平面延伸的多个部件。托盘部件包括一对间隔开的支撑件。冲击器工具可以可拆卸地支撑在相对于基部构件的固定位置的支撑件上，优选地大致平行于其。这些部件包括枢转地附接到基部构件的冲击驱动器工具致动器。一对假体部件可以在由假体部件的相应锥形环形部分限定的锥形锁定连接处连接。组件和冲击驱动器工具支撑邻近基座的假体部件和与冲击驱动器工具的轴向对准，假体部件通常位于一对间隔开的支撑件之间。冲击驱动器工具提供致动器，用于启动驾驶员以将负载传递到假体部件，以在锥形锁定连接处将部件驱动在一起。基座的间隔开的支撑件将假体和冲击驱动器的组件的相对端部保持成与基座构件固定的关系。
