Title: Device with movable buttons or switches

Description:
FIELD 
     The present teachings generally relate to devices, more specifically surgical devices that include a circuit board switch and/or buttons that are repositionable between two or more positions so that two or more functional states are enabled. 
     BACKGROUND 
     Typically, surgical devices have one functional element, thus if a different function is desired a surgeon will switch devices during a procedure to a device with a different function. However, some devices include a second functional element and each functional element is activated by actuating each individual button. For example, if the surgeon selects a device that has two buttons, one button activates monopolar cut and a second button activates bipolar coagulation, the device can only provide these functions. Thus, if bipolar cutting is desired the surgeon either may use bipolar coagulation for a longer period of time or the monopolar cutting for cutting or the surgeon can switch to a device that provides bipolar cutting. This may result in longer surgery times or a less than optional cut being performed. Further, switching devices in the middle of a procedure may result in the surgeon losing concentration, losing a feature of interest, extending surgery times, or a combination thereof. 
     Examples of some electrosurgical instruments may be found in U.S. Pat. Nos. 6,110,171; 6,113,596; 6,190,386; 6,358,268; and 7,232,440; and U.S. Patent Application Publication Nos. 2005/0113827; 2005/0187512; 2006/0084973; 2012/0123405; 2014/0276795; and 2014/0276799 all of which are incorporated by reference herein for all purposes. What is needed is a device that easily transforms between a plurality of different electrical states and functions. It would be attractive to have a device that can switch between two or more states and multiple states with a single button. It would be attractive to have a device that mechanically reconfigures states so that the circuitry of the device physically changes position, electrically reconfiguring the device relative to the buttons. The buttons would control the functional output of the device. What is needed is a device that can change states so that each button can provide multiple functions.

The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description. 
     The present teachings relate to a device that is changeable between two or more states. The device may be any device that functions to generate a signal, provide power, or both. The device may transmit a first set of signals in a first state and a second set of signals in a second state. The device may include one or more buttons or one or more keys and the one or more buttons or one or more keys may provide two or more signals depending on the position or state of the keys or buttons (buttons and keys as discussed herein are used interchangeably). The keys, buttons, or both and a circuit board may be movable relative to each other to create different signals so that the device provides different functions. The one or more buttons, one or more keys, or both may be present on a keyboard, a phone, computer, surgical device, or a combination thereof. Preferably, the present teachings relate to buttons on a surgical device. Preferably, the present teachings relate to a surgical device and associated componentry that form an electronic, ultrasonic, or motorized surgical system or a combination thereof. 
     The surgical device may be a mechanical device, an electromechanical device (e.g., a device with a mechanically moving element and an electrical element), an electrosurgical device, or a combination thereof. The surgical system may be any system that includes one or more of the devices taught herein. Preferably, the surgical system includes at least a surgical device with at least one state (e.g., configuration). The state may be a relative disposition or arrangement of any part of the device that moves relative to another part. For example, the selector assembly moves the buttons relative to the circuit board or vice versa so that the device changes between a first state (or first configuration) and a second state (or second configuration). The surgical system may include one or more bodies as taught herein, one or more ground pads, one or more generators, one or more electrosurgical devices, one or more ultrasonic devices, one or more motorized devices, one or more adjacent body components, or a combination thereof and the teachings herein of each device which are incorporated into the surgical system. The surgical device may be any device that may be used by a surgeon to perform a surgical procedure. The surgical device may function to be switched between two or more configurations, two or more states, or both. For example, the surgical device may be switched between an electrical state, an ultrasonic state, a motorized state, a non-powered state, or a combination thereof. The surgical device may be any device that may be switched between two or more states with one hand so that a user may switch between the states without the need for a second hand, without disrupting the procedure, or both. The surgical device may be any device and/or state that may be used ambidextrously, ambidextrously switched between states, or both. The surgical device may be used to cut, perform hemostasis, coagulate, desiccate, fulgrate, electrocautery, or a combination thereof. The surgical device may perform one or more functions. Preferably, the surgical device performs a plurality of functions. For example, the surgical device may perform a first function, second function, third function, fourth function, or more functions. The surgical device may be any device that includes bipolar capabilities, monopolar capabilities, non-electrosurgical capabilities, ultrasonic capabilities, motorized capabilities (e.g. powered movement to cut, grind, saw, drill or a combination thereof), or a combination thereof. The surgical device may be used in open surgery. The surgical device may be used for non-powered surgical purposes. For example, the surgical device may be used as forceps, tweezers, or both that may be used to grip an object, an organ, a vein, skin, tissue, the like, or a combination thereof. In another example, one or more parts of the device may include a sharp edge and may be used to cut, similar to that of a scalpel. The surgical device may include a handpiece and a generator. The surgical device may have one or more therapy signals that extend between the handpiece and the generator. 
     The surgical device has a body. The body may function to connect a functional element to a user interface. The body may provide power, signals, or both to the function element. The body and one or more functional elements may be one integral piece or the functional element may be removable from the body. The body may include a power source or be connected to a power source. The body of the device may house the components that are used to make the device functional. The body of the device can be a hand piece. The body of the device can be forceps. The body of the device may be a frame. The body of the device may connect working arms, one or more functional elements, or both. The body of the device may include or be connected to one or more activation buttons, at least one circuit board, a shuttle, the functional element, selector assembly, or a combination thereof. 
     The selector assembly allows the user to change between a plurality of functions of the surgical device. The selector assembly may function to change between multiple functions for each of the one or more activation buttons. The selector assembly changes the function of the one or more activation buttons by moving the one or more activation buttons, the circuit board, or both. The selector assembly is changeable between two or more positions so that each of the one or more activation buttons provide two or more functions. For example, the surgical device may perform or provide more functions than activation buttons are present on the device (e.g., one button may activate 2 or more, 3 or more, 4 or more, or even 5 or more functions). The selector assembly may longitudinally move along the surgical device (e.g., may move along in the direction of the longitudinal axis of the device (e.g., forceps, motorized device, ultrasonic device)); rotationally move around a component of the surgical device (e.g., the selector assembly may follow the contour of the surgical device in a direction substantially perpendicular to the longitudinal axis); the selector assembly may laterally move (e.g., from side to side without following the contour of the device); or a combination thereof. The longitudinal axis as discussed herein is the dimension with the longest length. The selector assembly may move along or within one or more channels. The selector assembly may be moveable by a sliding action, a leaf spring mechanism, a short throw lever assembly, a rack and pinion assembly, or a combination thereof. The selector assembly may include a portion that is located on a surface of the surgical device and a portion that extends into the surgical device. The selector assembly may change position through the use of a position change button. The position change button may be in communication with a mechanism or assembly that may allow for the selector assembly to move between positions when depressed. The selector assembly may be on the body, removeably attached to a body, movable along the body, or a combination thereof. The selector assembly may include the shuttle, the one or more activation buttons, the circuit board, a position change button, a leaf spring mechanism, a short throw lever assembly, a rack and pinion assembly, or a combination thereof. 
     The device (e.g., a surgical device) includes a moveable shuttle. The shuttle may be moveable relative to the body of the surgical device. The shuttle may move the device between a plurality of states (e.g., electrical states). For example, the device may be moved from a first state to a second state. The device may be moved between a first state, second state, third state, fourth state, or more states. The shuttle may move along a line or axis of the device; along a surface of the device; pivot as a lever on the device; rotate as a knob on the device; or a combination thereof. The shuttle may move between positions (e.g., first, second, third, or fourth positions) as the shuttle moves along the device. The shuttle may longitudinally move along the surgical device (e.g., may move in the direction of the longitudinal axis of the device); rotationally move around a component of the surgical device (e.g., may follow the contour of the surgical device in a direction substantially perpendicular to the longitudinal axis); the shuttle may laterally move (e.g., from side to side without following the contour of the device); or a combination thereof. The shuttle may move along the longitudinal axis of the surgical device. The shuttle may move in a direction substantially perpendicular to the longitudinal axis (i.e., laterally). The shuttle may move around a rotational axis that is substantially parallel to the longitudinal axis (i.e., rotationally). The shuttle may include one or more of a leaf spring mechanism, a short throw lever assembly, or a rack and pinion assembly that assist in moving the shuttle. The shuttle may be in communication with the one or more activation buttons, the one or more circuit boards, or both. When the shuttle is in communication with the one or more activation buttons, the one or more circuit boards are stationary relative to the body. When the shuttle is in communication with the one or more circuit boards, the one or more activation buttons are stationary relative to the body of the surgical device. When the shuttle is in communication with either the one or more circuit boards or the one or more activation buttons, the one or more activation buttons and the one or more circuit boards may move relative to each other. The shuttle may have two or more positions (e.g., at least a first position and a second position). The shuttle may have a plurality of positions. The shuttle may have a first position, second position, third position, fourth position, or more. The shuttle in one or more of the positions discussed herein may disable one or more of the states herein. The shuttle in a first position may disable a second electrical state, in a second position may disable a first electrical state and/or a third electrical state, or a combination thereof. For example, the shuttle in the second position may be positioned so that the first electrical state is disabled. The shuttle helps convert the surgical device between states based on the shuttle&#39;s position. For example, the shuttle in the first position will place the surgical device in the first state and when the shuttle is moved into the second position, the surgical device will be converted to the second state. The shuttle in a first position may align one or more activation buttons with one or more circuit board switches, one or more circuit board switches on a second circuit board, or both. The shuttle in a first position may misalign the one or more activation buttons with the first circuit board switches and align the activation buttons with the second circuit board switches, or vice versa. Alignment as discussed herein is when the button is located so that the button can move into contact with a switch and preferably is when the button can move linearly and substantially perpendicularly to the switch so that the switch is activated upon movement of the button. Misalignment as discussed herein is where the button when activated upon does not contact a switch causing an activation of that switch. The shuttle in the second position may align one or more of the activation buttons with one or more of the circuit board switches, one or more second circuit board switches, or both. The shuttle may be placed in two or more positions so that the one or more activation buttons align with or misalign with the one or more circuit board switches. 
     The position change button may function to convert the device between two or more positions. The position change button may be in communication with a mechanism or assembly to convert the device between positions (e.g., from a first position to a second position). The position change button when actuated may engage a mechanism or assembly to move the selector assembly from one position to another position by moving the shuttle, the circuit board, the activation buttons, or a combination thereof by converting mechanical potential energy into directional movement. The position change button is located on the exterior of the device. The position change button may include an actuator. The position change button may act upon a leaf spring mechanism, a short throw lever assembly, a rack and pinion assembly, or a combination thereof. 
     The leaf spring mechanism may convert the device between states (e.g., a first state and a second state). The leaf spring mechanism may include a position change button, an actuator block with a track, a plunger, a leaf spring, or a combination thereof. The actuator block may attach to the circuit board, shuttle, activation buttons, or a combination thereof. The actuator block may have a track. The actuator block track may be on the interior, exterior, or both of the handpiece. The actuator block track may have at least one position. The position change button may be used to convert the leaf spring mechanism between positions. The position change button may include a plunger. The plunger may fit into the track of the actuator block. When the position change button is acted upon, the position change button plunger may move between two or more positions of the actuator block. When the position change button plunger moves, the actuator block may change position so that the leaf spring can push the actuator block, which is connected to the shuttle, the activation buttons, the circuit board, or a combination thereof. The force of the leaf spring expanding may be converted into directional movement, moving the device into another position. When the actuator block is moved from one position to another position, the circuit board, the shuttle, the one or more activation buttons, or combination thereof may be moved relative to each other through the transformation of the potential energy stored in the leaf spring into directional movement. 
     The short throw lever assembly may be used to convert the device between a plurality of states (e.g., a first state and a second state). The short throw lever assembly when actuated may change the position of the selector assembly from one position to another. The short throw lever assembly may include a lever, a fixed pivot point, one or more moving pivot points, or a combination thereof. The lever may attach to the shuttle, the circuit board, the activation buttons, or a combination thereof at one of the one or more moving pivot points. The lever may pivot about a fixed point. When a force is put onto the lever, the lever may pivot around the fixed point pushing or pulling the circuit board, the shuttle, the activation buttons, or a combination thereof. The short throw lever assembly may move the activation buttons and circuit board into alignment or misalignment. The short throw lever assembly may move the selector assembly by moving the circuit board, the shuttle, the one or more activation buttons, or a combination thereof relative to each other, converting the device from one state to another state. 
     The rack and pinion assembly may be used to convert the device between a first state and a second state. The rack and pinion assembly may assist in changing the position of the selector assembly from one position to another position. The rack and pinion assembly may include a pinion gear, and one or more rack gears. The rack and pinion assembly may move the selector assembly through rotating a pinion gear in communication with one or more of the rack gears connected with the activation buttons, the shuttle, the circuit board, or a combination thereof. When the assembly is rotated, the teeth of the pinion gear intertwine with the teeth of the rack, which may be connected to the circuit board, the activation buttons, the shuttle, or a combination thereof, moving the circuit board and the activation buttons into alignment or misalignment with one another. 
     The one or more activation buttons may function to active or deactivate the functional elements. The one or more activation buttons may actuate one or more circuit board switches, align with one or more circuit board switches, or both. The one or more activation buttons may be a plurality of activation buttons. The one or more activation buttons may be a first activation button, a second activation button, a third activation button, a fourth activation button, or more activation buttons. Preferably, each actuation button may actuate one or more circuit board switches so that a plurality of functions may be provided by the surgical device. The one or more activation buttons may contact (e.g., through direct contact or indirect contact) a circuit board switch (e.g., a dome or membrane) to initiate one or more of the functional elements. The one or more activation buttons may move substantially linearly (e.g., perpendicularly to the switches). Each of the one or more activation buttons may provide a different function, control a different functional element, provide multiple functions through the same functional element, or a combination thereof. The one or more activation buttons may be located on the body of the surgical device, on the shuttle, or both. The activation button when depressed actuates a circuit board switch so that one or more of the functional elements of the surgical device are activated. The circuit board switch is actuated when the activation button is depressed, which completes a circuit and powers one or more of the functional elements. There may be more than one activation button present on the surgical device. Preferably there are a plurality of activation buttons. Preferably the one or more of the activation buttons may have a plurality of positions. For example, each of the one or more activation buttons may be moved between a first position and a second position. The one or more activation buttons may be longitudinally moveable along the longitudinal axis of the device, laterally moveable along a secondary dimension of the device (e.g., a direction substantially perpendicular to the longitudinal axis), rotatably moveable about the rotational axis, or a combination thereof. Preferably, the one or more activation buttons will move about the longitudinal axis. The one or more activation buttons may be static. The one or more activation buttons may be static relative to the body, to the shuttle, circuit board, or a combination thereof. The one or more activation buttons may be a rigid element, non-conductive element, or both. The one or more activation buttons may be constrained from motion by guides in the body. The one or more activation buttons when aligned with the circuit board or circuit board switches (i.e., electrosurgical switches) may contact the circuit board or circuit board switches when depressed, activating one or more functional elements. 
     The circuit board functions to activate or deactivate one or more of the functional elements. The circuit board functions to receive one or more user inputs and control one or more functional elements of the surgical device. There may be more than one circuit board in a surgical device. The circuit board may have surface mounted circuitry, through-hole circuitry, or both. Preferably, the circuit board has surface mounted circuitry. The circuit board may have components mounted or placed onto the surface. For example, all of the circuit componentry, including the circuit board switch, are mounted on the top surface of the circuit board to allow the circuit board to be mounted flat onto the mounting surface of the device. The circuit board may be of a through-hole construction. Through-hole construction fits the components with wire leads into holes in the circuit board. When more than one circuit board is present the circuit boards may be movable relative to each other. For example, one circuit board may be moved over or under another circuit board so that a different function may be activated. One circuit board may be movable and one circuit board may be static. Both circuit boards may be movable. Each of the one or more activation buttons may provide a different function, control a different functional element, provide multiple functions through the same functional element, or a combination thereof. The one or more circuit boards may be located on or within the body of the surgical device, on or within the shuttle, or both. The one or more circuit boards are used to activate a functional element of the surgical device. The one or more circuit boards have at least one switch per circuit board that interact with the one or more activation buttons. The circuit board switches may be surface mounted switches. When the circuit board switch is actuated by the depressed activation button, the circuit board switch closes a circuit of the circuit board and enables the functional element of the surgical device. There may be more than one circuit board present on the surgical device. The surgical device may include a plurality of circuit boards. For example, the surgical device has a first circuit board and a second circuit board. The first circuit board, when activated, enables a first functional element and the second circuit board, when activated, enables a second functional element. The surgical device may have one activation button that moves between the two circuit boards and aligns with the first circuit board when in the first position and the second circuit board in the second position. In the first position, the second circuit is misaligned with the activation button and in the second position, the first circuit board is misaligned with activation button. Preferably the one or more of the circuit boards may have a plurality of position. For example, each of the one or more circuit boards may be moved between a first position and a second position. The one or more circuit boards may be longitudinally moveable along the longitudinal axis of the device, laterally moveable along a secondary dimension of the device (e.g., substantially perpendicular to the longitudinal axis), rotatably moveable about the rotational axis (e.g., an axis that is parallel to the longitudinal axis), or a combination thereof. Preferably, the one or more circuit boards will move about the longitudinal axis. The one or more circuit boards may be static. The one or more circuit boards may be static relative to the body, to the shuttle, the activation buttons, or a combination thereof. There may be more than one circuit board switches on a circuit board. For example, there may be two circuit board switches located on the same circuit board (e.g., a first circuit board switch and a second circuit board switch). For example, both a first circuit board and a second circuit board may include a first circuit board switch and a second circuit board switch. When the first circuit board switch is depressed, a first function is performed and when the second circuit board switch is depressed, a second function is performed. The circuit board may include one or more switches. 
     The circuit board switches enable the surgical device to activate functional elements through interacting with the circuit board and the one or more activation buttons. Each of the circuit boards may include one or more switches and preferably a plurality of switches. The one or more switches may be a first switch, a second switch, a third switch, a fourth switch, a fifth switch, or more switches. The device may include the same number of switches as buttons. For example, the device may include two buttons and two switches. The device may include a different number of buttons and switches. For example, the device may include three switches and one button. In another example the device may include two buttons and three switches. The one or more circuit board switches may be flat, convex, concave, a dome switch, a membrane switch, an electrical switch, a capacitive sensor, a pressure sensor, or a combination thereof. Preferably, the one or more circuit board switches may be a dome switch. The one or more circuit board switches interact with the one or more activation buttons when the one or more activation buttons are aligned with the circuit board switches such that when the one or more activation buttons are depressed, the buttons make contact with and engage the one or more circuit board switches to complete the circuit, enabling a functional element of the surgical device. The circuit board switches may be activated without being contacted. For example, depression of an activation button may create a field that triggers the circuit board switch so that a function is activated. The one or more circuit board switches and the one or more activation buttons are brought into alignment by changing the position of the selector assembly. 
     The state (e.g., electrical state or mechanical state) of the surgical device is changeable so that a functional element is activated. The surgical device has at least two states. Each of the states provide one or more different functions. For example, the first state is a forceps and provides a bipolar therapy current and a second state is a probe that may provide cutting and provides a monopolar therapy current. The surgical device creates a first state when the selector assembly is in the first position. When the selector assembly is in the first position, at least one circuit board switch is aligned with at least one of the activation buttons so that when the activation button is engaged, the activation button contacts the circuit board switch on the circuit board, completing the circuit and enabling a first function. 
     The second state changes the surgical device (e.g., mechanically or electrically) into a secondary form to allow a second element of the surgical device to be used. The second state is created when the selector assembly is in the second position. In the second state the selector assembly is advanced to the second position where the selector assembly moves either the one or more circuit boards or the one or more activation buttons. When the circuit boards or activation buttons are moved, the previously enabled function is no longer accessible due to the misalignment or realignment of the activation buttons and the circuit board switches. In the second state one or more of the activation buttons may be misaligned with one or more of the circuit board switches so that the activation button that is misaligned is effectively disabled. In the second state, the selector assembly is in the second position so that the activation button and the circuit board switch on the circuit board may be misaligned, so when the activation button is depressed, the button does not contact the circuit board switch and does not enable one or more of the functional elements. The second state of the surgical device may realign one of the activation buttons with one of the circuit board switches so that a functional element is activated, which is different than the functional element activated in the first state. In the second state the shuttle is in the second position so that at least one of the activation buttons are aligned with another circuit board switch, differing from the alignment in the first state so when the activation button is depressed, the button makes contact with the circuit board switch, enabling a second functional element of the surgical device. For example, if the first functional element produces a therapy current, the second functional element may be a different therapy current. The second state of the surgical device may be a non-powered element. 
     The one or more functional elements are an integral part of the surgical device or a part that may be added to the surgical device so that the surgical device may be used to perform a surgical procedure. The surgical device has at least one functional element. The functional element may be actuated when the circuit is completed by depressing the one or more activation buttons. Preferably, the surgical device has more than one functional element. For example, the surgical device may be electrosurgical forceps where in the first state the electrosurgical forceps produce a therapy current and in the second state the surgical device would function as non-electrical forceps. Preferably, the surgical device has a plurality of functional elements (e.g., three or more, four or more, or even five or more). The functional elements may be electrical, motorized, ultrasonic, mechanical, or a combination thereof. 
     When the functional elements are electrical elements the functional elements use electricity to perform one or more portions of a surgical procedure. Electrical elements are functional elements that use electricity to operate. The electrical element may be an electrode, an electrical motor, an ultrasonic transducer, or a combination thereof. The first electrical element may be a motor and the second electrical element may be an electrode. The second electrical element may be an electrode, a second therapy current, a motor, an ultrasonic transducer, or a combination thereof. Preferably, the second electrical element is a second therapy current that passes through at least the second electrical element. The motor may be operated when an activation button is in a first position and the electrode may be activated when the activation button is in a second position. The surgical device may have at least one electrical element. The surgical device may have at least two electrical elements. The surgical device may have a plurality of electrical elements. 
     The electrical functional element of the surgical device may include one or more electrodes. Electrodes conduct electricity through the surgical device upon activation. Electrodes may conduct therapy currents. A therapy current may be a monopolar current, bipolar current, or a combination thereof. The therapy current may be used to cut, cauterize, coagulate, or a combination thereof during a surgery. The electrodes may conduct a therapy current that is used to actuate a motor. 
     The functional element of the surgical device may be a motor. A motor functions to move a component of the surgical device. The motor may be electrically powered, pneumatically powered, hydraulically powered, or a combination thereof. The motor may be used to cut, grind, saw, drill, or a combination thereof. For example, the motorized functional element of the surgical device may be a debrider, which has a stationary outer blade and rotating inner blade or the motorized functional element may be a second functional element such as irrigation or suction. In the first functional state, the debrider may be actuated and in the second functional state the irrigation or suction element may be actuated by an opening of a solenoid powered valve impinging on a fluid line. For example, the device in a first state may actuate a debrider function to cut a targeted area, and the device in a second state may actuate a vacuum source to remove debris and liquid from a targeted area, and in a third state may actuate an irrigation source to provide saline solution to a targeted area. The vacuum and irrigation may be obtained from a preexisting source and may be actuated by the activation of a solenoid. In another example, the device in a first state activates the debrider function and the device in a second state activates a bipolar coagulation function without activating the debrider motor. 
     The functional element of the surgical device may be an ultrasonic component. The ultrasonic functional element may be used to identify a targeted area, cut, coagulate, or a combination thereof. It is preferred that the ultrasonic element cuts and coagulates by converting the electrical energy to mechanical vibration that is applied to tissue. Ultrasonic capabilities can be combined with a monopolar function, a bipolar function, or both. For example, the device in a first state may be actuated to produce ultrasonic energy to cut a targeted area, and the device in a second state may actuate a bipolar therapy current to coagulate a targeted area. In a further example, the device in the first state sends ultrasonic energy to a targeted area, and in the second state sends both ultrasonic and bipolar energy to a targeted area to simultaneously cut and coagulate. 
     The functional element of the surgical device may be mechanical device. A mechanical functional device is substantially free of electricity or any other power source. The mechanical element may be using the surgical device to cut, grip, probe, saw, strike, or a combination thereof. 
     The surgical device may be a combination device. A combination device incorporates two or more structural elements into a single device to make a tool that is capable of performing multiple functions without switching handsets. 
       FIG. 1  illustrates a perspective view of one example of a surgical device  1  that is shown as an electrosurgical device  2 . The electrosurgical device  2  is shown as forceps  4  having a body  5  with a distal end  14  and a proximal end  16 . The distal end  14  includes a pair of working arms  6  with a blade electrode  8  there between. The blade electrode  8  is advanced forward into a first state  10  by the shuttle  20  being moved forward into a second position  24  (i.e. along the longitudinal axis  18 ). In the second position  24  both the first activation button  26  and the second activation button  28  are shown. 
       FIG. 2  illustrates a perspective view of the electrosurgical device  2  with the shuttle  20  (along the longitudinal axis  18 ) in the first position  22  and the blade electrode  8  in the second state  12  so that the blade electrode  8  is retracted between the pair of working arms  6 . When the shuttle  20  is in the first position  22  the first activation button  26  is exposed. 
       FIG. 3  illustrates a perspective view of an electrosurgical device  2  with a shuttle  20  in the first position  22 . In the first position  22  the first activation button  26  and second activation button  28  are exposed and the blade electrode  8  is retracted between the working arms  6  so that a second state  12  is created. 
       FIG. 4  illustrates a perspective view of an electrosurgical device  2  with the shuttle  20  in the second position  24 . As shown, both a first activation button  26  and a second activation button  28  are exposed for providing power to the blade electrode  8 . The blade electrode  8  is advanced forward into the first state  10  so that the blade electrode  8  extends beyond the pair of opposing working arms  6 . 
       FIG. 5  illustrates a selector assembly  38  including a shuttle  20  connected to a circuit board  40  at a connection region  50 . The printed circuit board  40  includes a plurality of switches (e.g., a first circuit board switch  42  and a second circuit board switch  44 ). As illustrated a first activation button  26  is aligned with a first electrosurgical switch  42  and a second activation button  28  is aligned with a second electrosurgical switch  44  so that when the first activation button  26  or second activation button  28  are actuated in the direction  52  contact is created with the first electrosurgical switch  42  and the second electrosurgical switch  44  respectively. The third electrosurgical switch  46  is misaligned with the activation buttons. 
       FIG. 6  illustrates the selector assembly  38  including shuttle  20  and circuit board  40  that are moved in the direction  48  so that the third circuit board switch  46  is aligned with the first activation button  26  so that when the first activation button  26  is moved in the direction  52  into contact with the third circuit board switch  46  an electrical mode is activated. The shuttle  20  and the circuit board  40  are connected together at a connection region  50  and move in unison. When the shuttle  20  is moved from position one  22  into the second position  24  the second activation button  28  is covered and misaligned so the activation button  28 , if actuated, would not contact any circuit board switch. The first circuit board  42  switch and second circuit board switch  44  are misaligned with all of the activation buttons  26 ,  28 . The blade electrode (not shown) is retracted. 
       FIG. 7  illustrates a selector assembly  38  including shuttle  20 , and activation buttons  26 ,  28 . The circuit board  40  includes a plurality of switches (e.g., a first electrosurgical switch  42  and a second electrosurgical switch  44 ). As illustrated a first activation button  26  is aligned with a first electrosurgical switch  42  and a second activation button  28  is aligned with a second electrosurgical switch  44  so that when the first activation button  26  or second activation button  28  are actuated in the direction  52  contact is created with the first electrosurgical switch  42  and the second electrosurgical switch  44  respectively. 
       FIG. 8  illustrates the selector assembly  38  including shuttle  20  and activation buttons  26 ,  28  are moved in the direction  64  so that the second activation button  28  is aligned with the first electrosurgical switch  42  so that when the second activation button  28  is moved in the direction  52  into contact with the first activation switch  42  an electrical mode is activated. The first activation button  26  is positioned so that it does not interact with the circuit board switches  42 ,  44 . The second circuit  44  board switch is positioned so it cannot be actuated by an activation button  26 ,  28 . The shuttle  20  includes the activation buttons  26 ,  28  and move in unison in direction  64  to place the device in position two  24 . 
       FIG. 9  illustrates a first electrosurgical switch  42  and a second electrosurgical switch  44  with a circuit board  40  including traces  54  that have a terminal  58  region. A dome  56  is in contact with and extends over the traces  54  so that when an activation device  70  actuates the dome  56  in direction  52  a signal is sent. 
       FIG. 10  illustrates a top view of a switch  72 . The switch  72  includes a button that can be a first activation button  26  or a second activation button  28 . 
       FIG. 11A  illustrates a side view of the switch  72  during an off position. In the off position the dome  56  is extended upward towards the activation device  70  that is connected to the first activation button  26 /second activation button  28 . 
       FIG. 11B  illustrates the switch  72  in an activation position. In the activation position, the dome  56  is actuated by the activation device  70  being pushed against the dome by the first activation button  26 /second activation button  28 . 
       FIG. 12A  illustrates the selector assembly  38  as a keyboard  62  with multiple activation buttons  26 ,  28 ,  30  aligned with multiple circuit board switches  42 ,  44 ,  46  located on the circuit board  40 , so when one or more of the activation buttons  26 ,  28 ,  30  are depressed in direction  52 , one or more of the circuit board switches  42 ,  44 ,  46  are actuated, respectively. The buttons  26 ,  28 ,  30  are connected to actuation devices  70 , so when the buttons  26 ,  28 ,  30  are depressed in the  52  direction, the actuating device  70  depress the respective circuit board switch  42 ,  44 ,  46 . 
       FIG. 12B  illustrates a selector assembly  38 , which is shown as a keyboard  62 . The circuit board  40  of the keyboard  62  is shown moving in the  48  direction from a first position  22  to a second position  24 . In the second position  24  alignment of the circuit board switches  42 ,  44 ,  46  are changed relative to the first position  22 . As shown activation button  26  is aligned with circuit board switch  44 , activation button  28  is aligned with circuit board switch  46  and activation button  30  is misaligned (i.e., does not align with a circuit board switch). So when the activation buttons  26  and  28  are depressed in the  52  direction, the actuation device  70  will contact the circuit board switches  44  and  46 . Similarly, Circuit board switch  42  is misaligned and does not align with an activation button and thus this functionality is effectively unactuatable. 
       FIG. 13A  illustrates the selector assembly  38  in position one. The selector assembly  38  is connected to the circuit board  40  through a leaf spring mechanism  96 . In position one, the activation buttons  26 ,  28  are carried on the shuttle  20  and are aligned with the circuit board switches  42 ,  44 . When activation buttons  26 ,  28  are depressed in the direction  52 , the activation button  26 ,  28  will contact circuit board switches  42 ,  44 , respectively. No activation buttons are aligned with circuit board switch  46 . The selector assembly includes a position change button  74  which is in communication with the leaf spring mechanism  96 . The leaf spring mechanism  96  includes an actuator block  98  with a track  110 , a plunger  108 , and a leaf spring  104 . The actuator block  98  attaches to the circuit board at region  106 . The track  110  of the actuator block  98  has a top position  100  and a side position  102 . The plunger  108  is connected to the position change button  74  and fits into the positions of the actuator block  100 ,  102  so when the position change button  74  is acted upon in direction  52 , the plunger  108  moves from the top position  100  to the side position  102 . When the plunger  108  moves, the leaf spring  104  can push the actuator block  98 , which is connected to the circuit board  40  at  106 , converting the device into position two. When the actuator block is moved from position one to position two, the circuit board  40  is moved relative to the activation buttons  26 ,  28 . To move the device back to position one, the position change button can be actuated, causing the plunger to move about the track of the actuator block clockwise so that the plunger returns to position one. 
       FIG. 13B  illustrates the selector assembly  38  in position two  24 . The selector assembly  38  is connected to the circuit board  40  through a leaf spring mechanism  96 . The leaf spring mechanism  96  moves the circuit board  40  in direction  48 , where the shuttle  20  holds the activation button  26  to align with the circuit board switch  46 . The second activation button  28  is misaligned with all of the circuit board switches  42 ,  44 ,  46 . The first circuit board switch  42  and second circuit board switch  44  are not aligned with any of the activation buttons. When activation button  26  is depressed in the direction  52 , it will contact the circuit board switch  46 . The leaf spring assembly  96  converts the device from position one  22  to position two  24  through actuating the position change button  74  in the direction  52 . The position change button depresses the plunger  108  causing the leaf spring mechanism  96  to relieve tension on the leaf spring  104  which expands and moves the circuit board  40  laterally by pushing the actuator block  98 , which is connected to the circuit board  40  at  106 , placing the device in the second position  24 . When the position change button  74  is depressed, the plunger  108  moves along the track  110  of the actuator block  98  from the top position  100  to the side position  102 . The circuit board  40  moves relative to the activation buttons  26 ,  28 . The activation buttons  26 ,  28  are stationary relative the circuit board  40 . 
       FIG. 14  illustrates the selector assembly  38  connected to the circuit board  40  through a short throw lever assembly  86  where the shuttle  20  holds the activation buttons  26 ,  28  aligns with the circuit board switches  42 ,  44  so that when the activation buttons  26 ,  28  are depressed in the direction  52 , the activation buttons  26 ,  28  will contact the circuit board switches  42 ,  44  respectively. In this position, the third circuit board switch  46  is not aligned with either of the activation buttons  26 ,  28 . The short throw lever assembly  86  includes a lever  92 , a fixed pivot point  88  that the lever rotates about, and moving pivot points  90  at the circuit board and the shuttle, respectively. The short throw lever assembly  86  converts the device between positions when moved in the  94  direction by laterally moving the shuttle  20  holding the activation buttons  26  and  28  in the  64  direction and the circuit board  40  in the  48  direction. The shuttle  20  and the circuit board  40  are connected by the lever  92  at moving pivot points  90 , so when the short throw lever assembly  86  is acted upon, the lever  92  pivots about the fixed point  88 , moving the shuttle  20 , which holds the activation buttons  26  and  28 , and the circuit board  40  into aligned or misaligned. 
       FIG. 15  illustrates the selector assembly  38  is connected to the circuit board  40  and shuttle  20  through a rack and pinion assembly  80 . The rack and pinion assembly  80  helps convert the device between a first position and a second position by allowing the shuttle  20 , carrying the activation buttons  26  and  28 , to move relative to the circuit board  40 . The rack and pinion assembly  80  includes a pinion gear  82  and a pair of rack gears  84 , each attached to the circuit board  40  and the shuttle  20 . As the pinion gear  82  rotates, the rack gears  84  laterally move the shuttle  20  in the  64  direction and circuit board  40  in the  48  direction placing the device into a second position, aligning or misaligning the activation buttons  26 ,  28  with the circuit board switches  42 ,  44 ,  46 . In the position shown, the activation buttons  26  and  28  are aligned with circuit board switches  42  and  44 , so when the activation buttons are depressed in the  52  direction, activation button  26  will contact circuit board switch  42  and activation button  28  will contact circuit board switch  44 . Circuit board switch  46  is not aligned with any activation buttons. A rack and pinion converts rotational movement to longitudinal movement or lateral movement.

For values which are less than one, one unit is considered to be 0.0001, 0.001, 0.01 or 0.1 as appropriate. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest value and the highest value enumerated are to be considered to be expressly stated in this application in a similar manner. 
     Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints. The use of “about” or “approximately” in connection with a range applies to both ends of the range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, inclusive of at least the specified endpoints.
