Abstract:
A remote control unit (370) for use with an ophthalmic surgical system having a main control console (46) with video display screen and operator interface. The remote controller (370) is connected by an electrical umbilical cord (702) to the main console and provides a second operator display (711) and membrane-switch (708) interface for use by a surgeon or other member of the surgical team. This remote control unit has its own housing (700) with a splash-resistant front face that is divided into primary and secondary operator interface panels (709, 710). The primary panel (709) includes a rectangular display field having a plurality of back-illumination lights (792) for selectively illuminating legends found on a replaceable legend card (780) that fits within a slot (782) behind the face plates. Control functions corresponding to the illuminated legends may be selected or de-selected by pressing nearby switches (712) arranged in locations adjacent to the display field. The secondary panel also contains membrane switches and legends illuminated by back-lighting. The remote console includes its own microcontroller which electronically receives information from and sends information to the main console via a serial communications interface. Through the use of replaceable legend cards, the remote console is capable of simulating surgical mode and procedure screens which are also displayed upon the CRT screen of the main console.
Abstract:
A microprocessor-based electronic control system for controlling microsurgical instruments includes a display screen (50) and a plurality of operator input switches (52) which support various enhanced user-friendly functions. The operator interface provides special utility display screens for allowing a user to change various default settings for operating parameters, the screen seen upon power up mode, and the language set used for the screens. The control system includes a main control console, and a processor which is programmed to display a variety of screens in a predetermined sequence or tree structure to facilitate user changes to the system. The control system also includes set-up screens for adjusting monitoring and warning sounds in tone and volume. Also, the control system provides a user-selectable rate of change in aspiration levels to permit users to obtain a speed of response in aspiration which they are accustomed or most comfortable with.
