    • A surgical system having feedback control for pneumatic actuators includes a pneumatic pressure source and a vitrectomy cutter having a cutting mechanism, a first pneumatic input port, and a second pneumatic input port. A pneumatic actuator is configured to direct pneumatic pressure to one of the first and second pneumatic input ports. A first pressure transducer is located and configured to detect actual pressure at the first pneumatic input port, and a second pressure transducer is located and configured to detect actual pressure at the second pneumatic input port. A controller communicates with the first and second pressure transducers and the pneumatic actuator. It is configured to change the pneumatic actuator actuation timing based on the data communicated from the first and second pressure transducers.
    • 具有用于气动致动器的反馈控制的手术系统包括气动压力源和具有切割机构,第一气动输入端口和第二气动输入端口的玻璃体切割切割器。 气动致动器构造成将气动压力引导到第一和第二气动输入端口中的一个。 第一压力传感器被定位和配置为检测第一气动输入端口处的实际压力,并且第二压力传感器被定位和构造成检测第二气动输入端口处的实际压力。 控制器与第一和第二压力传感器和气动致动器通信。 它被配置为基于从第一和第二压力传感器传送的数据来改变气动致动器致动定时。
