SPRING-MASS SURGICAL SYSTEM |
摘要 |
A high-speed surgical handpiece (10) of the kind suitable for vitreoretinal surgery having a cutter (44) and an actuator (310). The cutter (44) is a guillotine-type cutter activated by a spring-mass system excited at harmonic frequency by a piezoelectric actuator (310) that receives a driving signal from a driving controller. The controller can have control and display units with a plurality of input mechanisms receiving input from a user. The control unit produces a piezoelectric actuator output signal to excite the spring-mass system at harmonic frequency. Fast cutting rates with reduced duty cycle as well as a proportional mode of operation are available. Low degrees of vibration and noise generation are produced.
