摘要：
The present invention provides a system and a method for reducing pores, or air pockets, that form at the interface between the material used to attach or adhere the surface of a component, such as a prosthesis, to a site. A preferred embodiment of the invention includes an actuator that controls a coupler which transmits energy to a prosthesis being inserted into a material to reduce porosity at an interface between the prosthesis and the material. The system of the present invention can include an oscillating hand-held device that vibrates the stem component of an orthopedic prosthesis at a particular frequency and amplitude. The device is typically held by the hand of the surgeon, who guides the vibrating prosthesis into the cement-filled medullary cavity.
摘要（中）：
本发明提供一种用于减少在用于将诸如假体的部件的表面附接或粘附到部位的材料之间的界面处形成的孔或气囊的系统和方法。 本发明的优选实施例包括致动器，该致动器控制耦合器，该耦合器将能量传递到被插入到材料中的假体，以减少假体和材料之间的界面处的孔隙率。 本发明的系统可以包括以特定频率和振幅振动矫形假体的茎部分的振动手持装置。 该装置通常由外科医生的手握住，外科医生将该振动假体引导到填充有水泥的髓腔中。
