    摘要： An artificial hip joint includes a socket or acetabular portion and a femoral portion secured to the upper leg bone or femur. A continuous metal acetabular cup for an artificial hip joint is provided with a right cylindrical portion and chamfered dome which is of porous titanium or other suitable material, including a coating of either sintered fibers or sintered small particles such as spheres, to encourage early bone ingrowth, following force fit insertion of the cup into the acetabulum. A plastic insert having a central recess for receiving the femoral ball, is inserted into the cup and includes interlockng elements for holding the plastic insert firmly into the metal cup and against rotation, and a flange extending over the lip of the metal cup to preclude metal to metal contact.

    摘要： Surgical clamping instruments include a distal portion having distal tips configured to be driven to provide clamping force to multiple tissue pieces; a proximal portion including a compression actuator configured for operation by a user to drive the distal tips to apply compression force to the tissue pieces, and a shear actuator configured for operation by the user to drive the distal tips to apply shear force to the tissue pieces; and an intermediate portion interconnecting the proximal and distal portions. A method of joining tissues pieces together includes applying first and second force applicators to first and second surfaces of first and second tissue pieces, wherein the first and second surfaces oppose third and fourth surfaces of the first and second tissue pieces to be joined, respectively; applying compressive force, via the first and second force applicators, to drive the first and second pieces together; and applying shear force, via said first and second force applicators, to accurately align the third and fourth surfaces, so that the third and fourth surfaces are contacted to one another in a desired fit pattern.
