摘要： A torsional-mode ultrasonic vibration generator is manufactured with longitudinal slots extending along its horn which damp unwanted vibrational modes and allow it to be made significantly smaller than previous apparatus. The torsional-mode ultrasonic generator is operable with a suite of surgical tools, to perform portions of an orthopaedic arthroplasty revision procedure. Three of the tools are for removing bone cement from within a bone cavity on a prosthesis cemented into the bone cavity. Three other tools are for separating an uncemented prosthesis from ingrown bone by cutting the bone between the prosthesis and walls of the bone cavity. The seventh tool is provided with sensors to determine a separation between a bone-cutting tool head and a metal prosthesis, feedback from the sensors being used to control servo motors of an articulated mounting for the seventh tool, to maintain the separation at a desirable value.

摘要： A fractured hollow bone can be supported by forming a rigid plastics implant within a cavity of the bone, extending across the fracture. An access port aids removal or revision of the implant. The port comprises a hollow cylinder, with a distal end inserted through an aperture in an end of the bone into the cavity to surround a proximal end of the implant. The access port is connectable to a source of torsional-mode ultrasonic vibrations, which soften the plastics material of the implant, improving engagement between the implant and a threaded formation within the distal end of the access port. Removal of the source allows the access port to act as a guide passage, in line with the elongate implant. A cutting tool introduced through the access port is thus guided so that it can be used to hollow out the implant. Once sufficiently hollowed-out, the implant collapses within its surrounding balloon. The engagement of the access port with the proximal end of the implant allows the implant and balloon to be drawn out of the cavity. A particularly suitable cutting tool has a roughly cylindrical operative head comprising four equally-spaced fins separated by four part-circular grooves. The fins and grooves extend helically of the operative head. The distal end is concave. When activated by torsional-mode ultrasonic vibrations, the distal tips of the fins produce an effective longitudinal cutting action. Debris and softened plastics material flow proximally along the grooves away from the distal end where most cutting occurs.
摘要翻译：可以通过在骨（1）的空腔（2）内形成延伸越过骨折（4）的刚性塑料植入物（5）来支撑骨折的中空骨（1）。进入端口（7）用于帮助移除或修复植入物（5）。这包括中空圆柱体（9），其远端穿过骨（1）端部中的孔（16）插入腔体（2）中以围绕植入物（5）的近端（15））。进入口（7）可连接到扭转模式超声波振动源，软化植入物（5）的塑料材料，改善植入物（5）和螺纹结构（11）之间的啮合，接入端口（7）。超声波振动源的移除允许进入端口（7）充当与细长植入物（5）一致的引导通道（14）。通过进入口（7）引入的切割工具因此被引导，使得它可以用于挖空植入物（5）。一旦充分挖空，植入物（5）在其周围的气囊（6）内塌缩。进入口（7）与植入物（5）的近端（15）的接合允许植入物（5）和球囊（6）从空腔（2）中抽出。特别合适的切割工具具有大致圆柱形的操作头（21），其包括由四个部分圆形凹槽（25）分开的四个等距间隔的翅片（24）。翅片（24）和凹槽（25）在操作头部（21）的远端（26）和近端（28）之间螺旋地延伸。远端（26）是凹入的。当通过扭转模式超声波振动激活时，翅片（24）的远侧末端特别地产生有效的纵向切割动作。碎屑和软化的塑料材料沿着远离远侧端部（26）的沟槽（25）向近侧流动，其中大部分切割发生。
