MULTIFUNCTION FOOT PEDAL

摘要

A foot pedal with a treadle that pivots up and down to vary its pitch, and/or side to side to vary its yaw. The pivot range of motion is divided into a plurality of zones, each zone configured to correspond to a respective virtual switch. When the treadle is pivoted into one of the zones, the corresponding virtual switch is activated. The virtual switch controls an operatively coupled device such as a handpiece used in a surgical procedure.

1. A system for performing ocular surgery, comprising:
a handpiece for performing surgical procedures; an instrument host coupled to the handpiece that includes:
a data storage device configured for storing computer instructions;a processor communicatively coupled to the data storage device;a communications connection to the handpiece that provides operating instructions to the handpiece based on received control signals; andan electrical power connection to the handpiece that provides electrical power to the handpiece in accordance with the operating instructions; and a foot pedal communicatively coupled to the instrument host that provides the control signals, including:
a base; anda treadle pivotably coupled to the base on at least one rotational axis;wherein the range of motion of the treadle as it pivots around the axis comprises a plurality of non-overlapping zones, each zone corresponding to a virtual switch that is activated when the treadle is oriented within that zone, by sending a respective one of the control signals to the instrument host.
