Definitions

  • the present disclosure relates generally to foot pedal-operated controls, particularly for controlling surgical apparatuses.
  • Surgical apparatuses often include operating controls for regulating settings or functions of the apparatus.
  • Numerous types of apparatuses include a part in the form of a hand-held electrically operated medical implement or tool, commonly referred to as a handpiece. Operation of the apparatus requires control of various operating settings or functions required to use the handpiece.
  • Such apparatus may include a control cabinet, power supply, one or more pumps, motors, and the like, as well as associated electronic hardware.
  • a surgeon may use such an apparatus during eye surgery in order to sonically emulsify eye tissue, irrigate the eye with a saline solution, and aspirate the emulsified lens from the eye.
  • Foot pedals vary in design, but traditional designs incorporate one or more electro-mechanical switches to allow the surgeon to initiate various system control functions using the foot pedal. This is a convenient mechanism for the surgeon, since it does not rely upon another person such as a scrub tech or nurse to initiate these control functions, for example via a graphical user interface (GUI) on a main console of the apparatus.
  • GUI graphical user interface
  • electro-mechanical switches introduce a variety of issues.
  • a foot pedals incorporating a plurality of physical switches can complicate the design of the foot pedal, increase its cost, and increase the potential for failure of a switch.
  • the placement of the switches may be less than optimal for a particular user, and cannot be modified or adapted to accommodate the user. This can decrease their effectiveness and can create issues with ergonomics and the like.
  • the switches are typically uncovered, and may become fouled by saline solution or other debris that gets into the foot pedal, potentially resulting in failure or reduction in the life of components within the foot pedal.
  • 4,983,901 provide for a virtually unlimited number of control variations and modes for operating phacoemulsification apparatuses.
  • Additional single linear and dual linear foot pedal patents include 5,268,624; 5,342,293; 6,260,434; 6,360,630; 6,452,120; 6,452,123; and 6,674,030.
  • the pedal must be user friendly in order to provide a surgeon comfort and reliability in its use so as not to initiate disruption of the surgeon's concentration when performing surgery.
  • Prior art foot pedals employ a variety of side, top, toe, and heel switches to allow a surgeon to control a variety of apparatus functions.
  • such functions can include Reflux, CASE Up, CASE Down, IV Pole Up, IV Pole Down, Next Major Mode, Previous Major Mode, Next Submode, Previous Submode, Next Active Mode, Previous Active Mode, Toggle Continuous Irrigation, Single Cut Vitrectomy, and the like.
  • the foot pedal switches may be controlled by software, which may be configured using a computer-based GUI, for example. In a given configuration, foot pedal switch operations are relayed to the host software and translated into the corresponding configured function.
  • An illustrative embodiment includes a method of using a foot pedal to select multiple pre-programmed settings, comprising selecting a direction of movement of a treadle of the foot pedal, wherein the direction is selected from the group consisting of pitch and yaw; and moving the treadle in the selected direction to one or more selected from the group consisting of: a first location, wherein the first location is a first preprogrammed setting; a second location, wherein the second location is a second pre- programmed setting; and a third location, wherein the third location is a third preprogrammed setting.
  • a foot pedal comprises a treadle, wherein the treadle is capable of moving in at least one direction selected from the group consisting of pitch and yaw, and wherein at least one of the directional movements of the treadle is capable of acting as a switch.

  • FIG. 9 is another perspective view of a foot pedal showing the movement of the treadle in a yaw direction.
  • the functionality provided by electromechanical switches is produced instead by using the pitch of the foot pedal treadle in the vertical direction, or the yaw of the foot pedal treadle in the horizontal direction, or both.
  • a feedback signal may be provided to the user indicating the state of the pedal has been changed, such as an audible signal, a vibration signal, a visual signal such as a flashing light or an indicator on the GUI, or combinations of these.
  • a plurality of different conditions of the treadle may be used to define state changes in the foot pedal.
  • Such conditions may include, for example, a pivotably movable treadle that can pivot in a vertical direction about a horizontal axis, called pitch, or in a horizontal direction about a vertical axis, called yaw, or both.
  • the angle of pitch and/or yaw may be recognized as defined states or as points of transition from one state to another.
  • the maximums of the ranges of motion may also be recognized, such as the top and/or bottom of the pedal's pitch, or the maximum left and/or right yaw.
  • a particular speed and extent of motion such as a tap or stomp of the pedal, may be recognized.
  • a duration of maintaining a pedal position may also be recognized, such as pressing a pedal for a couple of seconds and releasing it to turn a feature on or off.
  • Such foot pedal states and/or state changes may be used to define a plurality of virtual switches. That is, the operation of a plurality of physical switches may be mimicked by a corresponding plurality of states or state changes of a single foot pedal treadle. The states or state changes of the treadle are used to define a plurality of virtual switches.
  • the pitch, or angle of incline, of the treadle from a reference position such as horizontal, and/or the yaw of the treadle from a reference position such as a center of a range of horizontal movement can be used to define a plurality of zones.
  • a plurality of zones may be defined, each zone existing between two different angles of pitch or yaw.
  • Such zones may be defined to be active or passive.
  • a plurality of active zones may be configured to be adjacent to each other, or alternatively two active zones may be separated by an inactive zone.
  • virtual switches can be used in conjunction with one or more physical switches.
  • one of a plurality of physical switches on or coupled to a foot pedal with a movable treadle may be used to turn on or off the virtual switch functionality of a foot pedal having predefined virtual switches.
  • a foot pedal tap may enter the mode where the user can control virtual switches based upon pitch or yaw.
  • moving the foot pedal to a predefined state such as into one of a plurality of defined foot pedal zones, may activate the corresponding virtual switch.
  • the activation may be confirmed by a visual, audible, or haptic signal to provide feedback to the user.
  • the pitch range of motion of a foot pedal treadle may be divided into four zones, with a dead-band at the top and bottom of the foot pedal travel range. When released, the treadle settles at a default position, such as toward the top of the range, when it is fully released.
  • the yaw range of motion of a foot pedal treadle may also be divided into four zones, with a dead-band at the left and right ends of the foot pedal travel range. When released, the treadle will settle at default position, such as the center of the range.
  • system control functions there are two primary types of system control functions.
  • One of these is the toggling of discrete functions, such as turning on and off a continuous flow of irrigation fluid.
  • the other primary type includes press-and-hold functions, such as raising and lowering an IV pole to a desired height. Both types of functions can be controlled using virtual switches.
  • the user may press the pedal treadle to a selected switch zone, and then quickly release the pedal.
  • foot pedal pitch zone 1 is defined as controlling irrigation fluid
  • the user may move the treadle into pitch zone 1 and quickly release it. The first such movement may turn irrigation on, and a second such movement may turn irrigation off.
  • mode activation occurs when the user holds the treadle in a specific switch zone for at least a defined amount of time, for example, for at least two seconds. The switch zone will then remain active until the user moves the pedal out of that specific switch zone.
  • the user may press the foot pedal treadle all the way down to its full travel position and hold it there for a predetermined duration, for example, for two seconds. Thereby, the mode is ended, which may be confirmed by one or more of an audible or haptic signal to the user or a visual indicator on the GUI. The user can then return the foot pedal to its default "zero" position to return to normal, non-virtual switch foot pedal operation.
  • the predetermined duration may be configurable.
  • the user may push the foot pedal treadle all the way to its right or left to the full extent of travel and hold for a predetermined, and possibly configurable, duration. Thereby, the mode is ended, which may be confirmed by one or more of an audible or haptic signal to the user or a visual indicator on the GUI. The user can then return the foot pedal to its default "zero" position to return to normal, non-virtual switch foot pedal operation.
  • the previously described exit from virtual switch on pitch or yaw procedure can act as a means for canceling or exiting from a switch activation procedure, without completing any switch activations.
  • the tap to enter the virtual switch on pitch mode may be defined as a quick transition from a first to a second pedal position, and back to the first.
  • the foot pedal range of motion may be partitioned into four different zones FPO, FPl, FP2, and FP3, corresponding to virtual switches SWO, SWl, SW2 and SW3.
  • Each switch may be configured for a specific function, or may also be disabled, for example via configuration software running on GUI host 101 or instrument host 102. Though these switch positions may correspond to the standard foot pedal positions FPO, FPl, FP2, and FP3, the switch zones could be configured independently as well.
  • the pedal may be programmed to have functionality that does not correspond to the standard foot pedal positions, and/or may be programmed with more or fewer pitch zones.
  • SWl IV Pole Up
  • SW2 Previous Major Mode
  • SW3 Next Major Mode
  • the user is a surgeon.
  • the surgeon enters the virtual switch on pitch mode by pressing the foot pedal into the SWO zone for a predetermined duration. This action causes the pedal to enter the switch on pitch mode, which is confirmed by an audible or haptic feedback and display on the GUI.
  • an IV Pole Down command is sent to the IV pole and it starts lowering. Any transition out of the SWO zone results in an IV Pole Stop command being sent to the IV pole, halting its downward motion.
  • the foot pedal may be partitioned in switch zones that are laid out from left to right.
  • SWO and SW1 are defined to be to the right of a center default pedal position or dead-band, and SW2 and SW3 to the right.
  • the functionality of the virtual switch on yaw example operates similarly with regard to the switch behavior. One difference is the zero may be the center dead-band reference instead of toward a limit of motion. From the switch on yaw mode of operation, holding the pedal for a predetermined duration in one of the dead-bands at the left and right limit of the yaw travel range would exit the switch on yaw mode.

  • phacoemulsification refers to a method of lens and cataract extraction from an eye.
  • the procedure includes an ultrasonically vibrated needle which is inserted through a very small incision in the cornea in order to provide energy for emulsifying or breaking up of the lens and cataract which then can be aspirated and removed through the incision.
  • the term "diathermy” refers to a method of cautery to seal severed or ruptured blood vessels. Diathermy is used in ophthalmic surgery to halt bleeding associated with surgical incisions.
  • the term “vitrectomy surgery” refers to a method employed during cataract surgery when the posterior capsular bag has been broken and in the treatment of retinal detachments resulting from tears or holes in the retina. In cataract surgery, the same incision used for the phacoemulsification handpiece is used for inserting the vitrector to remove the vitreous gel. Vitrectomy surgery typically involves removal of vitreous gel and may utilize three small incisions in the pars plana of the patient's eye. These incisions allow the surgeon to pass three separate instruments into the patient's eye to affect the ocular procedure. The surgical instruments typically include a vitreous cutting device, an illumination source, and an infusion port.
  • display or "display screen” as used herein shall mean a graphical user interface (GUI), a screen, a monitor, touch screen, or any other device known in the art for displaying a visual picture or representation.
  • GUI graphical user interface
  • a foot pedal may be attached to the medical device system by any mechanism known in the art, including, but not limited to, a wire connection and a wireless connection, e.g. Bluetooth® or IR.
  • a display screen of the medical device system may present the user with a picture or representation of the foot pedal detected. The picture or representation may show all the switches and directional movements available for programming the attached foot pedal.

Abstract

L'invention concerne une pédale de pied ayant une marche qui pivote vers le haut et vers le bas pour faire varier son pas, et/ou d'un côté à l'autre pour faire varier son lacet. La plage de pivotement de mouvement est divisée en une pluralité de zones, chaque zone étant configurée pour correspondre à un commutateur virtuel respectif. Lorsque la marche est tournée dans l'une des zones, le commutateur virtuel correspondant est activé. Le commutateur virtuel commande un dispositif couplé de façon fonctionnelle, tel qu'une pièce à main utilisée dans une intervention chirurgicale.
