摘要： A single-motor surgical system for operating a set of different surgical devices having different operational limits, consisting of a handpiece containing the motor and adapted to alternately receive a proximal portion of each of the surgical devices, each device having an indicator on its proximal portion that denotes its operational limit, the handpiece including an automatic sensor for sensing the indicator, and controls responsive to the sensor to automatically establish the operational limit of the motor in accordance with the respective surgical device received by the handpiece. In preferred embodiments, the system includes an arthroscopic handpiece as above and has a plurality of surgical devices adapted to receive different removable rotary tips that have different operational limits of rotation, each of the plurality of devices having a vacuum passage connectible at one end to a vacuum passage of the respective rotary tip and adjacent the other end, to a vacuum passage associated with the handpiece, whereby tissue severed by the rotary tip can be removed from the surgical site, the surgical device indicating to the sensor the rotational limits of the tips which the devices are adapted to receive.
摘要翻译：一种用于操作具有不同操作限制的一组不同手术装置的单电动机手术系统，包括容纳电动机并适于交替地接收每个外科手术装置的近端部分的手持件，每个装置在其近端部分上具有指示器其表示其操作限制，所述手持件包括用于感测所述指示器的自动传感器，以及响应于所述传感器的控制，以根据由所述手持件接收的各自的手术装置自动建立所述马达的操作极限。在优选实施例中，该系统包括如上所述的关节镜手柄，并且具有适于接收具有不同操作旋转限制的不同可移除旋转尖端的多个手术装置，所述多个装置中的每一个具有可在一端连接到相应的旋转尖端并且靠近另一端的真空通道连接到与手持件相关联的真空通道，由此可以从手术部位移除由旋转尖端切断的组织，外科手术装置向传感器指示尖端的旋转极限设备适合接收。
