Description

Technology Field

[0001] The present invention relates to the field of medical devices, and in particular to an ultrasonic scalpel, a surgical energy device, and a method for controlling the same. Background Technology

[0002] Ultrasonic scalpels provide ultrasonic energy in various laparoscopic and general surgeries and are primarily used for hemostatic separation of soft tissues and tissue coagulation. With the popularization of minimally invasive surgery, ultrasonic scalpels have already become common surgical tools and are widely used. US 2018 / 0333182 A1 discloses an ultrasonic surgical tool and a method for identifying tissue conditions and supplying energy to the surgical tool, wherein the surgical tool comprises an end effector having an ultrasonic blade and an RF electrode, a shaft assembly, a body, and a power controller. A first ultrasonic energy input is configured to operate from a first non-operating energy input state to a first operating energy input state. A trigger input is configured to operate from a non-operating trigger input state to an operating trigger input state. CN 113349889 A discloses an ultrasonic scalpel handle comprising a handle housing (11) and a transducer assembly (12). The transducer assembly (12) is integrally received within the handle housing (11) and can rotate about its own axis. The transducer assembly (12) includes a transducer shell (121) and a transducer (122) fixedly positioned relative to each other, and a conductive member (123) fixedly installed outside the transducer shell (121). However, the ease of operation of the two aforementioned ultrasonic surgical tools still needs to be improved. An ideal ultrasonic scalpel must simultaneously meet the following requirements.

[0003] First, safety in surgical manipulation is required. Conventional ultrasonic scalpel designs are equipped with an excitation button; that is, when the excitation button is pressed, the ultrasonic generator turns on and outputs energy, and when the excitation button is released, the ultrasonic generator immediately turns off and stops energy output. Since this effectively reduces the risk of the ultrasonic scalpel accidentally touching non-surgical human tissue while in the energy firing state and prevents unnecessary damage, most surgeons are trained to master the hand-controlled mode using the excitation button.

[0004] Second, there is a need to reduce the cost of existing ultrasonic scalpels. Currently, to reduce costs, ultrasonic scalpels are not used as disposable instruments, so sterilization and safety can only be ensured by strictly disinfecting the ultrasonic scalpel head.

[0005] Third, the ultrasonic scalpel must be equipped with convenience and stability in operation. The handheld portion of an ultrasonic scalpel generally includes an excitation button to control energy output and operation buttons to control the rotation, bending, and opening / closing of the function head. When using this instrument, surgeons must not only operate the excitation button and other different buttons, but also require a high level of coordination between different fingers because the force required for each finger varies. Therefore, many doctors habitually use a foot switch to replace the operation of one or more fingers of the surgeon, thereby reducing the burden on the surgeon's fingers and lowering the force and coordination requirements for the hands, which can make the operation of the instrument more stable.

[0006] Ultrasonic scalpel technology has evolved to date, and the hand control mode of this button has been matched with the foot mode of the foot switch to become a universally accepted surgical operation method, to the point where some doctors can only complete high-level surgeries by relying on the foot switch.

[0007] The objective of the present invention is to provide an ultrasonic scalpel, a surgical energy device, and a method for controlling the same that can replace a foot switch and simultaneously reduce the finger coordination requirements of the surgical operator.

Specific details for implementing the invention

[0094] In order to enable those skilled in the art to better understand the means of solution of the present invention, the technical means of solution of the embodiments of the present invention are described clearly and completely below in conjunction with the drawings of the embodiments of the present invention. It is obvious that the described embodiments are merely some embodiments of the present invention and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0095] It must be explained that terms such as “first,” “second,” etc., in the specification, claims, and drawings of the present invention are intended to distinguish similar objects and are not intended to describe a specific order or sequence. It should be understood that data used in this manner is interchangeable where appropriate, and that embodiments of the present invention described herein may be practiced in an order other than that shown or described herein. Furthermore, the terms “include,” “compose,” and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product, or device comprising a series of steps or units is not limited to the steps or units explicitly listed, and may include other steps or units not explicitly listed or unique to such process, method, product, or device.

[0096] As mentioned in the background technology, many surgical energy devices provide foot switches for selective use by the surgical operator to reduce finger strain and lower finger coordination requirements. However, foot switches have at least the following disadvantages.

[0097] First, since doctors must control the foot switch with one foot, the other leg must support most of the body weight; given that some surgeries are time-consuming and some last more than 10 hours, and because the frequency of surgeries is high throughout the year, the weight-bearing leg of a doctor accustomed to using the foot switch (the leg other than the one stepping on the foot switch) is very easily fatigued or even susceptible to damage (including muscles, joints, varicose veins, etc.).

[0098] Second, hospitals must purchase foot switches if even one surgeon needs to use them, even if not all surgeons are familiar with them. However, since the market price of foot switches is higher than that of surgical energy devices, the unit purchase cost increases significantly, and because operating room equipment requires regular sterilization and maintenance, the use of foot switches increases management costs.

[0099] Third, since there may be multiple instruments controlled by foot switches during surgery, there may be one or more foot switches under the surgeon's feet; if there are too many objects on the floor, it is easy to fall while walking, especially if the surgeon and nurse are highly focused on the surgery and cannot see the floor clearly.

[0100] Fourth, if different operating physicians performing various surgical procedures all require foot switches and must use them alternately, and if foot switches are required simultaneously due to the surgical schedule, it will seriously affect the quality of the surgery or disrupt the existing surgical schedule.

[0101] However, since the combination of scalpel and foot switch has already formed a unique combination of thinking, it is not easy to think about changing the habit of this mode that has been used for decades, and even skilled doctors cannot perform surgery smoothly without a foot switch, so the foot switch cannot be abandoned despite the fact that standing for a long time during surgery is not good and places a great burden on the legs.

[0102] In one embodiment of the present invention, an ultrasonic scalpel is provided, which includes a portable member and a control module, wherein an excitation button is installed on the portable member and the excitation button is connected to an input terminal of the control module;

[0103] The output terminal of the control module is electrically connected directly or indirectly to an energy generating device; in this embodiment, the two are connected via an electronically controllable switch, and in other embodiments, they may be directly connected via a wire; and when connected via an electronically controllable switch, when the excitation button is pressed, the control module controls the electronically controllable switch to close, and when the excitation button is released, the control module controls the electronically controllable switch to open;

[0104] Referring to FIG. 21, the control module performs the following procedure.

[0105] In response to a first trigger signal triggered by an external switching operation, the control module switches the operating mode of the excitation button to an operating mode in which the current switch state is changed by controlling an electronically controllable switch whenever the excitation button is pressed, and the changed switch state is maintained until the next time the excitation button is pressed. For example, under the premise of switching to the operating mode, the current surgical energy device is in a standby state (the electronically controllable switch is in an open state). When the excitation button is pressed, the control module controls the electronically controllable switch to close, at which time the operating system of the surgical energy device turns on the circuit, and the energy generator continuously outputs energy to the portable component, and energy continues to be output even when the excitation button is released; when the excitation button is pressed again, the control module controls the electronically controllable switch to open, at which time the operating system turns off the circuit, at which time the energy generator stops outputting energy to the portable component and returns to standby mode.

[0106] In another embodiment of the present invention, the control module is not electrically connected to the energy generator through an electronically controllable switch, but is directly connected by a wire, that is, the control module can directly drive the energy generator, and when the excitation button is pressed, the energy generator is driven to output energy; when the excitation button is released, the energy generator is not driven, and correspondingly, the energy generator stops outputting energy. The control module performs the following procedure. In response to a first trigger signal triggered by an external switching operation, whenever the excitation button is pressed, the control module controls the energy generator to change the current ultrasonic energy output state, and the changed ultrasonic energy output state is maintained until the excitation button is pressed the next time, for example, the current energy generator does not output energy, and when the excitation button is pressed, even if the excitation button is released, the energy generator continues to output energy until the excitation button is pressed again, and the energy generator stops outputting energy; to make the energy generator continuously output energy again, the excitation button only needs to be pressed again, and this is repeated.

[0107] In one embodiment of the present invention, the control module is not electrically connected to the energy generating device through an electronically controllable switch, but is electrically connected to the energy generating device through a power board; when the excitation button is pressed, the control module controls the power board to transmit a driving command to the energy generating device, and when the excitation button is released, the control module controls the power board to stop transmitting the driving command; and the control module performs the following procedure. In response to a first trigger signal, whenever the excitation button is pressed, the control module controls the power board to change the current driving command output state, and the changed driving command output state is maintained until the excitation button is pressed the next time, wherein the driving command output state is divided into a driving command transmission state and a driving command transmission suspension state, for example, the current energy generating device is not outputting energy, and when the excitation button is pressed at this time, even if the excitation button is released at this time, the power board continuously transmits a driving command to the energy generating device so that energy is continuously output, and when the excitation button is pressed again, the power board stops transmitting the driving command to the energy generating device, and the energy generating device correspondingly stops energy output; To have the energy generator continuously output energy again, simply press the button here again, and this repeats.

[0108] The portable member of the present embodiment can implement a "foot mode" without the need to connect to a foot switch, and the foot mode of the present specification does not mean a mode of controlling the operation of an energy generator by stepping on a button on a foot switch, but rather means that by changing the traditional operating logic (operating mode) of the excitation button through a first trigger signal or a second trigger signal triggered by an external release switching operation, energy can be continuously excited as if the user were stepping on a foot switch without the user always having to press the excitation button with a finger.

[0109] To facilitate the explanation of the relative positional relationship of each component of the ultrasonic scalpel, the above and below descriptions regarding the front and rear directions are both defined by referring to the direction observed when the operator holds and manipulates the ultrasonic scalpel, wherein the position where the ultrasonic scalpel acts on the surgical site is the front, and the position where the ultrasonic scalpel approaches the operator's (doctor's) body is the rear.

[0110] The ultrasonic scalpel system illustrated in FIG. 1 includes an ultrasonic scalpel and a power adapter (3) that supplies energy to the ultrasonic scalpel; wherein the ultrasonic scalpel includes an ultrasonic scalpel handle (1) and a cutter (2) that is detachably mounted on the ultrasonic scalpel handle (1).

[0114] In a structural embodiment of one ultrasonic scalpel of the present invention, as shown in FIGS. 2 to 10, a conductive member (123) is fixedly installed on the outer periphery of a transducer shell (121), and the conductive member is in the shape of a circular ring, and the axis of the conductive member and the axis of the transducer assembly (12) extend in the same line. Specifically, the conductive member includes a first conductive member and a second conductive member that are insulated from each other and are both in the shape of a circular ring, and the transducer (122) has two electrical connection wires (1224), namely a first electrical connection wire and a second electrical connection wire, and the two electrical connection wires are each electrically connected to two conductive members.

[0115] Two conductive parts are installed spaced apart in the axial direction of the transducer shell (121), and in this embodiment, the conductive member (123) comprises two conductive rings, namely a first conductive ring (1231) and a second conductive ring (1232), both made of a conductive material, and a spacer ring (1233) made of an insulating material installed between the first conductive ring (1231) and the second conductive ring (1232), wherein the first conductive ring (1231) constitutes the first conductive part, and the second conductive ring (1232) constitutes the second conductive ring (1232). The end of the first electrical connection wire (1224) is fixedly installed on the first conductive ring (1231) to provide an electrical connection, and the end of the second electrical connection wire (1224) is fixedly installed on the second conductive ring (1232) to provide an electrical connection.

[0116] The first conductive ring (1231), the second conductive ring (1232), and the spacer ring (1233) are installed to be relatively fixed on the outer periphery of the transducer shell (121). Specifically, between each conductive ring and the spacer ring (1233), a circumferential position limiting structure is installed to limit the relative rotation of both, and between the entire conductive member (123) and the transducer shell (121), a positioning structure is further installed to limit the rotation of the conductive member (123) and the axial movement of the conductive member (123).

[0117] Here, as illustrated in FIGS. 6 and 7, the transducer shell (121) includes a front shell (1211), a middle shell (1213), and a rear shell (1212) installed sequentially along the front and rear directions. A rubber pad (125) and a rubber ring (126) are installed between the front shell (1211) and the middle shell (1213) to provide a seal, and a rubber ring (126) is installed between the middle shell (1213) and the rear shell (1212) to provide a seal, and simultaneously, the transducer (122) housed in the transducer shell (121) is sealed to the transducer shell (121). A conductive member (123) is fixedly mounted on the middle shell (1213) and is located in the front part of the rear shell (1212).

[0118] The conductive member (123) further includes an insulating sleeve (1234), the insulating sleeve (1234) is fixedly installed over the outer periphery of the intermediate shell (1213), and the first conductive ring (1231), the spacer ring (1233), and the second conductive ring (1232) are jointly installed over the outer periphery of the rear tube section of the insulating sleeve (1234), and the area between the front part of the first conductive ring (1231) and the insulating sleeve (1234), the area between the rear part of the first conductive ring (1231) and the front part of the spacer ring (1233), the area between the rear part of the spacer ring (1233) and the front part of the second conductive ring (1232), and the area between the rear part of the second conductive ring (1232) and the front part of the rear shell (1212) are all positioned by matching each other through a positioning boss (1235) and a concave groove method, and accordingly, the conductive member (123) It is fixed to the transducer shell (121).

[0119] As illustrated in FIGS. 3 and 5, an electrical connection element (13) is further installed in the handle housing (11), and the electrical connection element (13) is located on the circumferential outer side of the transducer assembly (12), and the electrical connection element (13) is in contact with the outer periphery of the transducer shell (121) and is connected to the conductive part. Specifically, the electrical connection element (13) includes a first electrical connection element (131) and a second electrical connection element (132) that are independent of each other, and both the first electrical connection element (131) and the second electrical connection element (132) are made of a metal material and have a certain elasticity along their own length direction, and both are installed spaced apart along the front-rear direction of the handle housing (11), and the first electrical connection element (131) is elastically in contact with the outer periphery of the first conductive ring (1231) inwardly along the radial direction of the transducer shell (121), and the second electrical connection element (132) is the transducer The second conductive ring (1232) is elastically contacted inwardly along the radial direction of the shell (121). While the entire transducer assembly (12) rotates about its own axis relative to the handle housing (11), the first electrical connection element (131) and the first conductive ring (1231), and the second electrical connection element (132) and the second conductive ring (1232) are always in contact to maintain an electrical connection.

[0120] As illustrated in FIG. 5, in this embodiment, the electrical connection element (13) is installed in the handle housing (11) and positioned in an upper position, which is positioned above the transducer assembly (12) so that the electrical connection element (13) is lowered to the outer periphery of the transducer assembly (12) to maintain a more stable electrical connection.

[0121] Accordingly, by simply connecting the power cord to the electrical connection element (13) inside the handle housing (11), the power cord can be drawn out from the bottom of the handle housing (11) and connected to the power supply. Therefore, while the transducer assembly (12) rotates around its own axis in the handle housing (11), the power cord does not rotate together with it, effectively preventing a series of problems such as the power cord extending from the rear part of the handle housing (11), which causes the arm to be easily fatigued due to the large force applied to it, and the power cord getting tangled.

[0122] In another structural embodiment of the ultrasonic scalpel of the present invention, as illustrated in FIGS. 11 to 19, in this embodiment, a conductive member (123) is fixedly installed at the rear end of a transducer shell (121), and the rear end of the transducer shell (121) itself may be installed in an open manner, and the conductive member (123) closes the transducer shell (121) at the rear end. A conductive part is installed at the rear end of the conductive member (123), and an electrical connection element (13) is installed in a handle housing (11) and is located at the rear of the transducer assembly (12), and the electrical connection element (13) is elastically contacted to the conductive part.

[0123] Specifically, the conductive part includes a first conductive part and a second conductive part installed insulated from each other, and the transducer (122) has two electrical connection wires, namely a first electrical connection wire and a second electrical connection wire (not shown), and the first electrical connection wire and the first conductive part are electrically connected, and the second electrical connection wire and the second conductive part are electrically connected. The electrical connection element (13) also includes a first elastic electrical connection member (13a) and a second elastic electrical connection member (13b) that are independent of each other but installed insulated from each other, and the first elastic electrical connection member (13a) is in contact with the first conductive part, and the second elastic electrical connection member (13b) is in contact with the second conductive part. Since the first and second conductive parts are in the shape of a disc or a circular ring with the axis of the transducer assembly (12) as the center of rotation, the first elastic electrical connection member (13a) and the second elastic electrical connection member (13b) can each maintain contact with the first and second conductive parts, respectively, while the transducer assembly (12) rotates around its own axis.

[0124] In this embodiment, the conductive member (123) comprises a plate body (1230) and a first conductive sheet (123a) and a second conductive sheet (123b) made of a metal material and fixedly installed on the plate body (1230). Here, the first conductive sheet (123a) is in the shape of a disc, and the second conductive sheet (123b) is in the shape of a circular ring and is installed surrounding the outer circumferential side of the first conductive sheet (123a). The first conductive sheet (123a) and the second conductive sheet (123b) are installed spaced apart along the radial direction of the conductive member (123), that is, the outer circumferential wall of the first conductive sheet (123a) and the inner circumferential wall of the second conductive sheet (123b) have a constant distance in the radial direction of the conductive member (123). The first conductive sheet (123a) constitutes a first conductive portion, and the second conductive sheet (123b) constitutes a second conductive portion.

[0125] A first through hole (123c) and a second through hole (123d) are installed in the plate body (1230) along its own thickness direction, and a first electrical connection wire is installed through the first through hole (123c) and fixed to the first conductive sheet (123a) by welding to provide an electrical connection, and a second electrical connection wire is installed through the second through hole (123d) and fixed to the second conductive sheet (123b) by welding to provide an electrical connection.

[0126] As illustrated in FIGS. 12 and 18, the first elastic electrical connection member (13a) and the second elastic electrical connection member (13b) are both elastic pieces made of metal material, and the lower end of the first elastic electrical connection member (13a) and the lower end of the second elastic electrical connection member (13b) are each fixedly installed in the handle housing (11), and the upper end of the first elastic electrical connection member (13a) is pressed forward against the rear side of the first conductive sheet (123a), and the upper end of the second elastic electrical connection member (13b) is pressed forward against the rear side of the second conductive sheet (123b).

[0127] Accordingly, by simply connecting the two conductive wires of the power cord to the first elastic electrical connection member (13a) and the second elastic electrical connection member (13b) respectively, the power cord can be drawn out from the bottom of the handle housing (11) and connected to the power supply. Therefore, while the transducer assembly (12) rotates around its own axis in the handle housing (11), the power cord does not rotate together with it, effectively preventing a series of problems such as the power cord extending from the rear part of the handle housing (11), which causes the arm to be easily fatigued due to the large force applied, and the power cord getting tangled.

[0128] The ultrasonic scalpel of the present embodiment can also be switched back to the previous operating mode via a second trigger signal triggered by an external release switching operation, and specifically, the control module also performs the following procedure.

[0129] In response to the second trigger signal, the control module returns the operating mode of the here button to the operating mode prior to switching; whereby the external release switching operation is the same as or different from the external switching operation.

[0130] The specific operation for switching the operating mode according to the aforementioned first trigger signal and second trigger signal is as follows (since the switching principle of the first trigger signal and the second trigger signal is the same, the following description uses an external switching operation to trigger the first trigger signal as an example).

[0131] In the first case, only one excitation button is installed on the portable component, and the excitation button can be used to trigger a mode switch of the control module, but since the excitation button itself must control energy output / stopping through a press / release operation, a method must be used where the excitation button is not clicked or long-pressed, for example, the excitation button can be double-clicked or multi-clicked within a preset short time.

[0132] In the second case, a plurality of excitation buttons may be installed on the portable member, or other operation buttons (15) excluding the excitation button (14) as shown in FIG. 20, such as a function button (for selecting a cutting function or a solidification function), a power gear button (for adjusting power size), and an operation button that controls any one of the operations of rotation, bending, or opening / closing of the function head, etc., may be used, and a single operation button excluding the excitation button originally installed on the handle or a combination of multiple operation buttons, such as a double-click (multi-click) function button or a power gear button, or two or three buttons among a simultaneous press function button, a power gear button, and an excitation button, or a press sequence of a preset function button-power gear button-excitation button or other free combination (not limited to the use of specific buttons in a single sequence) may be used to trigger the trigger control module to activate the foot mode.

[0133] In the third case, the mode switch can be triggered using a new button specifically designed for the corresponding mode switch, for example, a mode switch button such as a function button, or a DIP switch is toggled to a first position to switch to a first operating mode, and toggled to a second position to switch to a second operating mode.

[0134] In one embodiment of the present invention, a surgical energy device having a first operating mode and a second operating mode is provided, and the embodiment of the present invention may be applied to the field of ultrasonic scalpels, such as soft tissue cutting hemostatic scalpels and ultrasonic bone scalpels; it may also be applied to the field of laser scalpels or electric scalpels or other surgical scalpels.

[0135] The surgical energy device includes an energy generating device, a portable component, and a control module, and is described in detail as follows.

[0136] The energy generating device generates energy, and in the case corresponding to the application scenario of an ultrasonic scalpel, the energy generating device is an ultrasonic generator; in the case corresponding to the application scenario of a laser scalpel, the energy generating device is a laser generator; and in the case corresponding to the application scenario of an electric scalpel, the energy generating device is an electric signal generator.

[0137] The present invention is not limited to the three surgical energy devices described above and can be used in other medical devices that can be connected to a foot switch; for example, if the surgical energy device is a medical smoker, the energy generating device is an inhalation pump, and the medical smoker is used in the operating room to make the surgical environment smoke-free.

[0138] If the surgical energy device is a vacuum suction device, the energy generating device is a vacuum pump;

[0139] If the surgical energy device is a perfusion pump, the energy generating device is a perfusion pump;

[0140] If the surgical energy device is a robotic hand with toggle rotation, the energy generating device is a motor;

[0141] If the surgical energy device is a unipolar electrocoagulation pen or a bipolar electrocoagulation tweezers, the energy generating device may be an electric signal generator, etc., and further examples are not provided here. The two existing buttons of the product are a high-power button and a low-power button, respectively, and in the existing mode, the circuit is turned on when both are pressed and turned off when released; when switching the operating mode by adopting the solution means of the present embodiment, for example, if the high-power button and the low-power button are pressed simultaneously for 2 seconds (this method is merely an example), it switches to foot mode, and if the high-power button is pressed again, high-power output is continuously performed until the high-power button is pressed again to stop the high-power output; the same applies to the low-power button.

[0142] A portable member is electrically connected to an energy generating device via an electronically controllable switch, and one or more operation buttons are installed on the portable member, at least one of which is an excitation button (14); taking an ultrasonic scalpel as an example, the operation buttons installed on the handles of different models of ultrasonic scalpels are different, for example, there may be one excitation button (14) installed, or there may be an excitation button (14) with a corresponding different function (e.g., cutting or coagulation function) or different power, and other operation buttons (15), such as a function button (for selecting the cutting function or coagulation function) and a power gear button (for adjusting the power level), may be installed in addition to the excitation button (14). The present invention does not limit the button type after removing the excitation button (14) from the portable member or whether other operation buttons (15) exist in addition to the excitation button (14). Furthermore, the present invention does not limit the installation relationship between the energy generating device and the portable member to an integrated installation method or an installation method in which the energy generating device is installed inside the portable member.

[0143] The input terminal of the control module is electrically connected to an operation button, and the output terminal is electrically connected to an electronically controllable switch; the control module controls the surgical energy device to switch between a first operating mode and a second operating mode according to a preset first trigger signal and a second trigger signal, wherein the first trigger signal and the second trigger signal can each define the same operation or a different operation, and below, the first operating mode and the second operating mode are described first, and then the switching between the two different operating modes is described.

[0144] The two operating modes are specifically as illustrated in FIG. 21.

[0145] The first operating mode is the general mode (hand control mode), and the control logic of the single excitation button of the surgical energy device in standby mode is as follows. When the excitation button is pressed, the control module controls the electronically controllable switch to close, at which time the device turns on the circuit, and the energy generator continuously outputs energy to the portable component; when the excitation button is released, the control module controls the electronically controllable switch to open, at which time the device turns off the circuit, at which time the energy generator stops outputting energy to the portable component and returns to standby mode. That is, under the premise that the system power is turned on, the surgical energy device is in an operating state only during the time period when the excitation button is pressed, and is in a standby state during other times.

[0146] The second operating mode is "foot mode," and the control logic for a single excitation button of a surgical energy device in standby mode is as follows. When the excitation button is pressed once, the state of the surgical energy device changes before and after the press. For example, when the surgical energy device is currently in a standby state (the electronically controllable switch is open), when the excitation button is pressed, the control module controls the electronically controllable switch to close, at which time the device turns on the circuit, and the energy generator continuously outputs energy to the portable component, and even when the excitation button is released, the energy continues to output; when the excitation button is pressed again, the control module controls the electronically controllable switch to open, at which time the device turns off the circuit, at which time the energy generator stops outputting energy to the portable component and returns to standby mode.

[0147] It must be explained that defining the second operating mode as "foot mode" means that this new control mode can reduce the requirements for hand strength and coordination of the surgeon performing the surgery without a foot switch, and can achieve a level of flexible control that is essentially the same as when using a foot switch, and does not mean a mode implemented using a foot switch. However, the present invention does not exclude the possibility of using a foot switch, which means that finger coordination can achieve or even exceed the level of finger coordination when using a foot switch without using a foot switch.

[0148] Hereinafter, various embodiments of a method for switching between two different operating modes are described.

[0149] In one embodiment of the present invention, one or more of the operation buttons trigger a control module according to a preset operation, and various triggering methods include,

[0150] A method of clicking a single operation button, excluding the button here, once or for a long time; a method of double-clicking or multi-clicking one or more operation buttons within a preset time;

[0151] A method of pressing multiple control buttons simultaneously;

[0152] A method of sequentially pressing multiple operation buttons according to a preset order; and

[0153] A method of toggling a DIP switch among the operation buttons; includes, but is not limited to.

[0154] In summary, although the Here button can be used to trigger a mode switch of the control module, since the Here button itself must correspondingly control energy output / stop through push / release operations, a method that does not click or long-press the Here button must be used, for example, the Here button can be double-clicked or multi-clicked within a preset short time; the control module can be triggered to activate Foot mode by using a single operation button or a combination of multiple operation buttons excluding the Here button originally installed on the handle, for example, a double-click (multi-click) function button or a power gear button, or two or three buttons among a simultaneous press function button, a power gear button, and the Here button, or by a press sequence of a preset function button-power gear button-Here button or other free combinations (not limiting the use of specific buttons in a single sequence); In addition, a mode switch can be triggered using a new button specifically designed for the mode switch, such as a mode switch button like a function button, or a DIP switch may be toggled to a first position to switch to a first operating mode and toggled to a second position to switch to a second operating mode.

[0155] In one embodiment of the present invention, the control module is connected to an external human-computer interaction device via a wired or wireless method, and the control module is triggered by inputting a command to the control module through the human-computer interaction device. For example, the control module can be controlled to activate a corresponding general mode or foot mode through operation on the touchscreen by connecting the control module to the touchscreen via a wired method; or the switching between the general mode and foot mode can be implemented by selecting an application (App) on a mobile terminal that is wirelessly connected to the control module.

[0156] The embodiments of the above-mentioned operation button and the method through a human-computer interaction device may be implemented independently, but the integration of the different embodiments is not excluded in the same surgical energy device system.

[0157] In one embodiment of the present invention, a surgical energy device is initialized to a first operating mode after power is turned on, and when a first trigger signal triggers a control module, the control module controls the system to switch to a second operating mode, that is, activates a foot mode; and when an external cancel trigger operation is received, the control module controls the system to switch to the first operating mode, that is, returns to a normal mode. Of course, the initialization state may be set to the second operating mode, and the preset operation of the operation button that switches from the first operating mode to the second operating mode may be the same as or different from the preset operation of the operation button that switches the system from the second operating mode to the first operating mode.

[0158] The present invention provides a surgical energy device capable of switching operating modes, thereby considering a conventional operating mode in which the device outputs energy when the excitation button of a conventional surgical energy device handle is pressed and stops energy output when the excitation button is released, while simultaneously providing a foot mode operating method that does not require a foot switch to change the control mode of the excitation button for energy output, and the control method (mode switching operation) is as follows:

[0159] When the power of a surgical energy device is turned on, a predefined trigger action is input to redefine the control mode of the excitation button for energy output so that there is no energy output in the initial state, the device outputs energy when the excitation button is pressed for the first time, and the device stops energy output when the excitation button is pressed again; and

[0160] The step includes turning off the power of the surgical energy device or inputting a predefined trigger action, causing the button here to return to the initial control mode for the energy output.

[0161] Since the embodiment of this control method belongs to the same concept as the embodiment of the surgical energy device described above, the embodiment of this control method is cited by reference to the entire embodiment of the surgical energy device.

[0162] The conventional operating mode of the excitation button of a surgical energy device is such that the circuit is turned on when pressed and turned off when released, and this conventional general mode is compatible with the doctor's usage habits, and in particular, since the doctor's surgical ability is achieved through the gradual accumulation of previous surgical experience, this conventional design cannot be canceled; secondly, from the perspective of ergonomics, the general mode (hand control mode) is a relatively safe design, and if the scalpel head of the device inadvertently comes into contact with human tissue of a non-surgical subject when energy is fired, it may cause unnecessary damage.

[0163] In cases where a conventional general mode must be maintained, or during a stage where continuous energy output is required during surgery, if the solution of the present embodiment is used, the operating mode of the here button can be switched through an external trigger switching operation, so the surgeon does not need to always press the here button with their finger or always step on the foot switch, thereby preventing the doctor from causing damage or pain to the finger bones by always pressing the here button during a long surgery time, and also prevents the burden on the leg caused by the doctor supporting body weight with one foot (the foot not stepping on the foot switch) for a long time, while simultaneously achieving finger coordination that is basically consistent with the state of using the foot switch.

[0164] It must be explained that, in this specification, relational terms such as first, second, etc., are merely for distinguishing one entity or operation from another entity or operation and do not require or imply that any actual relationship or order exists between these entities or operations. Furthermore, since the terms “include,” “comprehensively,” or other variations refer to non-exclusive inclusion, a process, method, article, or apparatus comprising a series of elements may not only include these elements but also include other elements not explicitly enumerated, or include elements inherent to such process, method, article, or apparatus. Unless further limitations are given, an element limited by the phrase “includes one ……” does not exclude the existence of other identical elements in the process, method, article, or apparatus comprising the element.

[0165] The above is merely a specific embodiment of the present invention, and it should be noted that a person skilled in the art may make slight improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
