IPC: A61F9/00
Filed: 1992-04-09
Granted: 1994-09-01
Abstract: An aspiration control system includes a motor (18) and vacuum pump (22) which are controlled by a system controller (26), in accordance with input commands to provide a precise, continuously variable vacuum or negative pressure within a vacuum chamber (38) and surgical handpiece (70). The resulting vacuum is proportional to the control signal sent from the system controller (26) to the motor (18). A transducer (36) samples the vacuum output and produces a signal fed to the system controller (26). The signal is compared with a variable input signal set by a potentiometer (34) or other signal source activated by the input commands so that the transducer signal tracks the voltage source signal. Therefore, the vacuum output of the vacuum pump and motor relates directly and predictably to the input commands. In one embodiment the motor is a brushless DC motor. The system may also include a pinch valve (76) provided on a fluid aspiration conduit communicating between the surgical handpiece (70) and vacuum chamber (38) so that the fluid aspiration at the handpiece (70) may be controlled independently from the negative pressure level created in the vacuum chamber (38). <IMAGE>
