For example, in the exemplary embodiment, afoot pedal 160 is removably coupled tosurgical generator 110 to enable an operator to provide input tosurgical generator 110. In one embodiment, the input device is integrated withsurgical generator 110. In another embodiment, the input device is remote fromsurgical generator 110 and coupled thereto. - Different types of
handpieces 120 may be used withsurgical generator 110 based on a type of medical procedure and/or a type of surgical implement. For example,various handpieces 120 may have different configurations and/or properties (e.g., acoustical characteristics, resonance frequency), and/or various surgical implements may requirehandpieces 120 of different sizes and/or configurations. In the exemplary embodiment, an identifier (not shown) enablessurgical generator 110 to automatically identifyhandpiece 120. For example,surgical generator 110 may read and/or detect a resistance identification, an RFID tag, and/or another identifying component to differentiatehandpiece 120 fromother handpieces 120. Additionally or alternatively, an operator may manually identifyhandpiece 120. In at least some embodiments, the identifier is associated with multiple medical procedures and/or surgical implements. In such embodiments, the operator may provide, andsurgical generator 110 may receive, one or more inputs to select a medical procedure to be performed and/or a surgical implement to be interfaced. - In this manner, one or
more handpieces 120 may be replaced between medical procedures. In at least some embodiments,handpiece 120 is removed after each patient such thathandpiece 120 may be autoclaved between medical procedures to substantially ensure sterility for one or more subsequent patients. Accordingly,handpiece 120 is configured to withstand multiple autoclave procedures. - In the exemplary embodiment,
handpiece 120 includes anouter housing 170, ahorn 180 extending longitudinally fromouter housing 170, anend effector 190 coupled to horn 180, and a sheath 195 (shown inFIG. 2 ) coupled toouter housing 170 and extending about and spaced radially fromhorn 180 and/orend effector 190.

Alternatively,handpiece 120 may apply any energy that enablessurgical generator 110 and/orhandpiece 120 to function as described herein. - In the exemplary embodiment,
handpiece 120 is configured to provide an ergonomic interaction with an operator including, without limitation, a surgeon, a doctor, a surgery assistant, a nurse, a veterinarian, and/or other medical personnel present for a medical procedure. Other shapes and/or sizes ofhandpiece 120 may be included in other surgical system embodiments. In at least some embodiments,handpiece 120 is configured to interact with and/or be utilized by a robotic and/or haptic arm for robotic (e.g., fully automatic or programmed) and/or remote control (e.g., direct human control with end points or boundaries) ofhandpiece 120. -
FIG. 2 is a cross-sectional view ofhandpiece 120. In the exemplary embodiment,outer housing 170 houses at least aninner housing 200 and at least a portion of a transducer system or, more specifically,load cell 210. In the exemplary embodiment,load cell 210 is configured to detect a first force and/or pressure applied to loadcell 210 and transmit to surgical generator 110 (shown inFIG. 1 ) a pressure signal associated with and/or indicative of the first pressure. The first pressure is associated with a force and/or pressure between end effector 190 (shown inFIG. 1 ) and a surgical implement in contact withend effector 190, which, in turn, directly applies a force and/or pressure to horn 180. - In the exemplary embodiment, a
biasing mechanism 220 is positioned withinouter housing 170 to counteract, reduce and/or limit the first pressure applied to loadcell 210. More specifically,biasing mechanism 220 is moveable between an unflexed or home position and a flexed position. In this manner,load cell 210 “floats” withinouter housing 170. As the first pressure applied to loadcell 210 generally increases, in the exemplary embodiment,biasing mechanism 220 moves toward the flexed position. Conversely, as the first pressure applied to loadcell 210 generally decreases, in the exemplary embodiment,biasing mechanism 220 moves toward the home position. In the exemplary embodiment,biasing mechanism 220 includes aspring plate 230 and awave spring 240 that is configured to compress as the first pressure increases and/or expand as the first pressure decreases. Alternatively, any type ofbiasing mechanism 220 may be used that enableshandpiece 120 to function as described herein. In at least some embodiments,load cell 210 is fixedly coupled withinouter housing 170. - In the exemplary embodiment,
outer housing 170 defines a cavity therein that is sized and/or configured such thatinner housing 200 is retained withinouter housing 170. More specifically,outer housing 170 and/orinner housing 200 includes at least oneretaining mechanism 250 that facilitates counteracting, reducing, and/or limiting the first pressure applied to loadcell 210. For example, in the exemplary embodiment, retainingmechanism 250 is positioned withinouter housing 170 betweeninner housing 200 andload cell 210 to prevent and/or limitinner housing 200 from moving towardload cell 210 beyond a predetermined position. In the exemplary embodiment, a portion of retainingmechanism 250 is positioned at the predetermined position within agroove 260 defined by an inner surface ofouter housing 170. In the exemplary embodiment, retainingmechanism 250 includes anopening 270 extending longitudinally therethrough, and astandoff 280 coupled toinner housing 200 extends throughopening 270 such thatstandoff 280 is configured to directly apply the first pressure to loadcell 210. In at least some embodiments,standoff 280 may be a spring. Alternatively, any type ofretaining mechanism 250 and/orstandoff 280 may be used that enableshandpiece 120 to function as described herein. - In the exemplary embodiment,
inner housing 200 houses at least a portion ofhorn 180 and at least a portion of the transducer system or, more specifically, vibratingmechanism 290 coupled tohorn 180. In the exemplary embodiment, vibratingmechanism 290 is a piezoelectric stack that is configured to generate vibratory energy (e.g., ultrasonic energy) upon receiving a control signal to activate a weld cycle. In the exemplary embodiment,horn 180 is configured to transmit the vibratory energy to an operative site. More specifically,horn 180 is coupleable to endeffector 190 such that the vibratory energy is transmitted to endeffector 190 throughhorn 180. Alternatively, the vibratory energy may be transmitted to the operative site using any mechanism that enableshandpiece 120 to function as described herein. - The transducer system includes at least vibrating
mechanism 290 andload cell 210. In this manner, the transducer system is configured to detect the first pressure, transmit the pressure signal, and generate ultrasonic vibratory energy. In the exemplary embodiment, vibratingmechanism 290 is remote fromload cell 210. Alternatively, vibratingmechanism 290 may be adjacent and/or integrated withload cell 210, orload cell 210 may be adjacent and/or integrated with vibratingmechanism 290. For example, the first pressure may be determined based on a pressure detected by vibratingmechanism 290, and/orload cell 210 may be configured to generate vibratory energy. - In at least some embodiments,
handpiece 120 includes a series of electrical contacts that are coupled to vibratingmechanism 290. In such embodiments, the electrical contacts are moveable between a closed configuration and an open configuration such that the electrical contacts are electrically and/or communicatively coupled and/or decoupled, respectively. In such embodiments, as pressure applied to endeffector 190,horn 180, and/orload cell 210 generally increases, the electrical contacts move toward the closed configuration, thereby couplingsurgical generator 110 to vibratingmechanism 290. Conversely, as pressure applied to endeffector 190,horn 180, and/orload cell 210 generally decreases, in such embodiments, the electrical contacts move toward the open configuration, thereby decouplingsurgical generator 110 from vibratingmechanism 290. Alternatively, the electrical contacts may be positioned anywhere withinhandpiece 120 that enablessurgical system 100 to function as described herein. -
FIG. 3 is a flowchart of anexemplary method 300 of operatingsurgical system 100. During operation, in the exemplary embodiment,handpiece 120 is identified based on an identifier and/or selected based on a type of medical procedure and/or surgical implement. In the exemplary embodiment,surgical generator 110 retrieves one or more settings associated withhandpiece 120, the medical procedure, and/or the surgical implement frommemory device 140 based on the identifier. The settings are used bysurgical generator 110 to provide one or more control signals tohandpiece 120. Settings retrieved frommemory device 140 may include, without limitation, frequencies, voltages, currents, and/or control algorithms. For example, in the exemplary embodiment, the setting retrieved frommemory device 140 includes a predetermined first force and/or pressure range that enables vibratory energy transfer to the surgical implement, as described below. - Upon identification and/or selection of
handpiece 120 and retrieval of one or more settings frommemory device 140,surgical system 100 is generally ready to affect the surgical implement. In the exemplary embodiment,end effector 190 is positioned 310 at least partially within the patient and in contact with the surgical implement. More specifically, the operator useshandpiece 120 to apply force and/or pressure to the surgical implement, which, in turn, applies a force and/or pressure to horn 180 andinner housing 200. As a result,standoff 280 applies the first pressure to loadcell 210, which detects 320 the first pressure and transmits 330 the pressure signal fromhandpiece 120 tosurgical generator 110. - In at least some embodiments,
output device 150 presents an indication of the pressure to the operator. For example, in one embodiment, a visual display presents a visual indication of the applied pressure relative to the first pressure range such that the operator is able to visualize what, if any, corrections need to be made in order to provide a pressure within the first pressure range. Additionally or alternatively, an audio output device presents an audible tone indicative of the applied pressure, and/or a tactile output device presents vibrations indicative of the applied pressure. The tone and/or vibrations may include three rates, volumes, and/or intensities: a first rate, volume, and/or intensity indicating the pressure is below the first pressure range, a second rate, volume, and/or intensity indicating the pressure is within the first pressure range, and a third rate, volume, and/or intensity indicating the pressure is above the first pressure range. As such, the audible tone and/or the vibrations enable the operator to understand the applied pressure relative to the first pressure range without diverting the operator's visual attention from the patient and/or surgical implement. - In the exemplary embodiment, when the pressure is below the first pressure range,
output device 150 presents no visual or audible indicator. When the pressure is within the first pressure range,output device 150 presents a ready light and a beep that is emitted at one second intervals. When the pressure is above the first pressure range,output device 150 presents an “over pressure” display and a beep that is emitted at half-second intervals. Alternatively,output device 150 may present any indication to the operator that enablessurgical system 100 to function as described herein. - In the exemplary embodiment, when the applied pressure is within the predetermined pressure range, the operator presses
foot pedal 160 down to initiate transmission of the control signal to activate a weld cycle. More specifically,surgical generator 110 transmits the control signal to handpiece 120 upon determining and/or identifying that the applied pressure is within the first pressure range and/or determining and/or identifying thatfoot pedal 160 is pressed down. In one embodiment, the control signal is transmitted to handpiece 120 upon receiving the first indication that the applied pressure is within the first pressure range and then the second indication thatfoot pedal 160 is pressed second. In another embodiment, the control signal is transmitted to handpiece 120 upon receiving the second indication thatfoot pedal 160 is pressed down and then the first indication that the applied pressure is within the first pressure range. - In the exemplary embodiment, vibrating
mechanism 290 receives 340 the control signal to activate a weld cycle and generates 350 vibratory energy upon receiving the control signal. The vibratory energy is transferred throughhorn 180 andend effector 190 to the surgical implement. The vibratory energy propagates through the surgical implement to vibrate the surgical implement and an adjacent surgical implement, which generates heat and a weld therebetween. - During operation of
handpiece 120 in the active weld cycle,output device 150 presents an indication of the active weld cycle to the operator. For example, in one embodiment, an audio output device presents an audible tone indicative of the active weld cycle. In the exemplary embodiment, the active weld cycle stops when the weld is complete. More specifically,surgical generator 110 determines and/or identifies that the weld is complete based on a predetermined amount of energy or work applied byhandpiece 120, and stops transmission of the control signal and/or transmits a second control signal to stop the active weld cycle when the weld is complete. In the exemplary embodiment, the amount of energy applied to the surgical implement is approximately 100 Joules (J). Alternatively,surgical generator 110 may apply any amount of energy that enablessurgical system 100 to function as described herein. -

As a first force and/or pressure applied topositional sensor 510 and/orbiasing mechanism 520 generally increases, in the exemplary embodiment,biasing mechanism 520 moves toward the flexed position. Conversely, as the first pressure applied topositional sensor 510 and/orbiasing mechanism 520 generally decreases, in the exemplary embodiment,biasing mechanism 520 moves toward the home position. - In the exemplary embodiment, the first pressure is associated with a force and/or pressure between
end effector 490 and a surgical implement in contact withend effector 490, which, in turn, directly applies a force and/or pressure to horn 480. In the exemplary embodiment,biasing mechanism 520 is a coil spring configured to compress as the first pressure increases and/or expand as the first pressure decreases. Alternatively, any type ofbiasing mechanism 520 may be used that enableshandpiece 420 to function as described herein. - In the exemplary embodiment,
positional sensor 510 is configured to detect the first pressure applied topositional sensor 510 and/orbiasing mechanism 520 and transmit to surgical generator 110 a pressure signal associated with and/or indicative of the first pressure. More specifically,positional sensor 510 detects a longitudinal or axial compression and/or extension ofpositional sensor 510 and/orbiasing mechanism 520 and determines the first pressure based at least in part on the axial compression and/or extension. In the exemplary embodiment,positional sensor 510 is a linear variable differential transformer and/or a Hall effect sensor. Alternatively,positional sensor 510 may be any sensor that enableshandpiece 420 to function as described herein. - In the exemplary embodiment,
outer housing 470 defines a cavity therein that is sized and/or configured such thatinner housing 500 is retained withinouter housing 470. More specifically,outer housing 470 and/orinner housing 500 includes at least oneretaining mechanism 550 configured to prevent and/or limitinner housing 500 from moving away frompositional sensor 510 and/orbiasing mechanism 520 beyond a predetermined position.
