    摘要： A tool driver having a shaft with a longitudinal axis and opposite ends. A boss is positioned at one of the ends. A tool collet is positioned at the other of the ends. The boss has a bore extending axially thereof forming debris cavity. An actuator on the shaft. A pair of oppositely disposed pins on the actuator. The pins are movable in relation to the boss in response to movement of the actuator. The actuator and the pins move as a unit axially of the boss between an at rest position and a static position. The pins are movable between an extended position and a retracted position as the actuator moves between an at rest position and a static position, whereby a tool can be positioned on the tool driver when the actuator is in its static position and held in operable position on the tool driver when the actuator is in its at rest position.

    摘要： A ball and socket joint for implanting in the body is provided which comprises (1) a ball; (2) a cup to be affixed to bone which includes (a) a spherical cavity and (b) two coaxial pin members which extend into the cavity; and (3) a bearing member surrounding a portion of the ball and rotatable within said spherical cavity about said coaxial pin members, the bearing member having an asymmetric opening therein, the opening having an angular extent of less than 180.degree. in at least one plane. In certain preferred embodiments, the cup includes first and second portions, the first portion to be affixed to bone, the second portion having associated therewith the coaxial pin members and being moveable with respect to the first portion to provide a plurality of possible orientations for the axis of rotation of the bearing member within the spherical cavity.
