Description

[Technical Field]

[0001] The present invention relates to the field of medical devices, and in particular to surgical energy machines and ultrasonic scalpels. [Background technology]

[0002] Surgical energy machines, such as ultrasonic scalpels that use ultrasonic energy, are widely used in various laparoscopic surgeries and general surgeries. Before surgery, medical staff in the hospital equipment department must prepare surgical instruments and consumables. When using energy machines, they generally need to check their service life.

[0003] In order to record the remaining number of times that a power tool can be used, power tools with a usage count statistics function have been developed in the prior art. For example, a Chinese utility model patent with publication number CN211187449U discloses an ultrasonic scalpel equipped with an information recording device that records the number of times the transducer has been used and the number of remaining times it can be used, and equipped with a display device that displays the information received from the information recording device for the surgical operator's reference. It also discloses that when the number of times the information recording device records reaches or exceeds a preset usage count threshold, a warning message is issued.

[0004] However, in the prior art, checking the device status, such as the number of uses, requires connecting an external power source to activate the ultrasonic scalpel, resulting in cumbersome wiring work. The prior art also includes surgical energy machines, such as the Chinese patent publication number CN207804334U, which discloses a cableless ultrasonic surgical system, which includes an energy storage device in the drive handle to power the ultrasonic driver, allowing the ultrasonic scalpel to be used without an external power source. While this eliminates the need for a power cord, powering the ultrasonic scalpel with a built-in battery to check the device status outside of surgery results in a loss of electrical energy. Furthermore, cableless ultrasonic surgical systems are relatively expensive and have inferior battery life and power output stability compared to wired ultrasonic surgical systems that use external AC power sources, so wired ultrasonic surgical systems remain the mainstream mechanical product. Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a surgical energy machine and an ultrasonic scalpel that can display device status parameters with low power consumption without being connected to an external power source. [Means for solving the problem]

[0008] Specifically, the surgical energy machine is connected to an external power source via a power connector, the control terminal of the first power switch tube is connected to the built-in battery via the operation button, and when the first power switch tube is turned on, the negative pole of the built-in battery is connected to both the control unit and the first power consumption circuit; a control terminal of the second power switch tube is connected to one end of the first power switch tube, and is arranged so that when the second power switch tube is turned on, the positive electrode of the built-in battery is connected to both the control unit and the first power consumption circuit; The positive or negative terminal of the built-in battery is not connected to the second power consumption circuit, When the surgical energy machine is disconnected from the external power source and the operating button is pressed, the built-in battery triggers the first power switch tube to be turned on, which in turn triggers the second power switch tube to be turned on, putting the control unit and the first power consumption circuit into an operating state.

[0010] Furthermore, the opening and closing circuit further includes a third power switch tube and a fourth power switch tube, both of which are initially in an off state, the third power switch tube being provided between the second power consumption circuit and the negative electrode of the external power supply, and the fourth power switch tube being provided between the second power consumption circuit and the positive electrode of the external power supply; The control terminal of the third power switch tube is connected to an external power source via a power connector, and the control terminal of the fourth power switch tube is connected to the third power switch tube, and in response to the surgical energy machine being connected to the external power source, the third power switch tube and the fourth power switch tube are both changed from an OFF state to an ON state. Specifically, when the third power switch tube is turned ON, the negative pole of the external power source is connected to the second power consumption circuit; a control terminal of the fourth power switch tube is connected to one end of the third power switch tube, and is arranged so that when the third power switch tube is turned on, the positive electrode of the external power supply is connected to both the second power consumption circuit and the control unit; When the surgical energy machine is connected to an external power source, it triggers the third power switch tube to be turned on, and the turning on of the third power switch tube further triggers the fourth power switch tube to be turned on, thereby activating the control unit and the second power consumption circuit.

[0011] Furthermore, the second power consumption circuit is a driving circuit or a digital processing circuit.

[0012] Furthermore, the operating button is a dedicated button for controlling and activating the first power consumption circuit, or The operation button is a function button of the surgical energy machine, and the function button has a first operating mode and a second operating mode. When the surgical energy machine is disconnected from an external power source, the control unit controls the function button to operate in the first operating mode, i.e., when the function button is pressed, it triggers the first power switch tube to be turned on. When the surgical energy machine is connected to an external power source, the control unit controls the function button to operate in the second operating mode, i.e., when the function button is pressed, it performs a function other than triggering the first power switch tube to be turned on.

[0013] Furthermore, the other function other than the trigger for turning on the first power switch tube includes any one of the following functions: the function button is a trigger button, and when the trigger button is pressed, an energy generator of the surgical energy machine is triggered to generate energy; the function button is a power level button, and when the power level button is pressed, the power level button adjusts the output power of an energy generator of the surgical energy machine; or The function button is a cutter head control button, and when the cutter head control button is pressed, the cutter end of the surgical energy machine performs a clamping operation.

[0015] Furthermore, the operation button When the operation button is pressed, the first power switch tube is maintained in an on state, When the operation button is released, the first power switch tube is configured to change from an ON state to an OFF state.

[0016] Furthermore, the control terminals of the second power switch tube and the fourth power switch tube are both connected to the positive electrode of the built-in battery via resistors, and in an initial state, the second power switch tube and the fourth power switch tube are both in an OFF state because their gate voltages are higher than an ON voltage threshold; In response to the first power switch being turned on, the second power switch tube is turned on by having its gate voltage pulled down, and in response to the third power switch tube being turned on, the fourth power switch tube is turned on by having its gate voltage pulled down.

[0017] Furthermore, the second and fourth power switch tubes are P-type MOS tubes, and the first and third power switch tubes are N-type MOS tubes.

[0018] Furthermore, the fourth power switch tube is connected to the control terminal of the first power switch tube via a resistor; When the surgical energy machine is connected to an external power source, turning on the fourth power switch tube triggers the first power switch tube to turn on, connecting the control unit to the negative pole of the external power source.

Prevent high-power circuits from being powered by the built-in battery, reducing the demand for battery capacity and reducing battery power consumption. [Brief explanation of the drawings]

[0025] In order to more clearly describe the embodiments of the present invention or the technical solutions in the prior art, the following briefly describes the accompanying drawings used in the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention, and other drawings can also be obtained by those skilled in the art from these drawings without creative efforts.

[0026] [Figure 1] FIG. 1 is a structural schematic diagram of a surgical energy machine having a dual-mode power supply circuit provided in an exemplary embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0027] In order to help those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Any other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative work fall within the protection scope of the present invention.

[0028] It should be noted that the terms "first," "second," etc. in the present specification, claims, and drawings are used to distinguish between similar objects and are not necessarily used to describe a particular order or chronology. Such terms, as used herein, should be understood to be interchangeable, where appropriate, so that the embodiments of the present invention described herein can be performed in orders other than those illustrated or described herein. Furthermore, the terms "comprise" and "have," and any variations thereof, are intended to cover non-exclusive inclusions; for example, a process, method, apparatus, product, or apparatus comprising a series of steps or units is not limited to those steps or units expressly recited, but may include other steps or units not expressly recited or inherent in the process, method, product, or apparatus.

[0029] Before surgery, medical staff in the hospital equipment department need to prepare surgical instruments and consumables. When using energy-saving devices, they generally need to check their service life to prevent the device from discovering that its remaining usage count is zero after the surgery has begun. A conventional solution to this problem is to manually record the remaining usage count of each energy-saving device when it is deployed after operation. A more advanced approach is to have the energy-saving device itself incorporate a statistical function for remaining usage counts so that the equipment department can query it in real time. However, because responsibilities are clearly defined within each process within a hospital, surgeons are not required to query and record the remaining usage count before canceling the surgery. Therefore, the equipment department must query the remaining usage count after powering on the energy-saving device during pre-surgery inspection. Because manually recording the remaining usage count and querying the power-on status are both inconvenient, the concept of the present invention is to provide a solution for conveniently querying the remaining usage count of a surgical energy-saving device without connecting it to an external power source.

[0030] In one embodiment of the present invention, a surgical energy machine having a dual-mode power supply circuit is provided, which is configured to be connected to an external power source via a power connector 6. Referring to FIG. 1 , the surgical energy machine includes an operation button 1, an internal battery 2, a control unit 3, a first power consumption circuit 41, and a second power consumption circuit 42. The second power consumption circuit 42 is a driving circuit or a digital processing circuit. The driving circuit may be configured as a driving energy generator, i.e., a power amplification module of an energy generator for a transducer, or as a driving switch or an electric machine. The digital processing circuit may be a digital circuit such as a CPU or DSP. The first power consumption circuit 41 consumes less power than the second power consumption circuit 42 and is configured to present a status parameter of the surgical energy machine under the control of the control unit 3, such as the remaining number of times the machine can be used. Several types of representation formats of the first power consumption circuit 41 are described below.

[0031] In a first form, the first power consumption circuit is a display unit, for example a liquid crystal display, arranged to display status parameters of said surgical energy machine under the control of the control unit.

[0032] In a second form, the first power consumption circuit is a speaker unit and is arranged to play a voice message under the control of the control unit, for example "There are currently 7 available uses remaining."

[0033] In a third form, the first power consumption circuit is an indicator light device, which may include various colors, for example, a green light indicates that the remaining number of uses is 20 or more, a yellow light indicates that the remaining number of uses is 3 or more but less than 20, and a red light indicates that the remaining number of uses is less than 3. The present invention does not limit the colors used to reflect the status parameters of the surgical energy machine, and for example, the remaining number of uses can also be indicated by different brightnesses of the indicator light, with brighter lights indicating more uses and darker lights indicating fewer uses. For example, different indicator light positions can be marked with ">20," "[5-20]," or "<5," and the corresponding indicator light can be lit depending on the actual remaining number of uses.

[0034] Regarding the remaining number of times that the transducer can be used, an information recording device can be installed to record the actual number of times that the transducer is used, and the remaining number of times that the transducer can be used can be calculated, as in the prior art CN211187449U mentioned in the background art. When an external power source is not connected, the control unit and the first power consumption circuit are triggered, and the control unit queries the remaining number of times that the transducer can be used from the information recording device and transmits the query result to the first power consumption circuit, thereby realizing the notification function.

[0035] In order to realize driving the first power consumption circuit 41 without connecting an external power source, the surgical energy machine further includes an opening / closing circuit, and in this embodiment, the opening / closing circuit may be designed as follows:

[0036] Referring to FIG. 1, the opening and closing circuit includes a first power switch tube 51 (i.e., switch tube Q1 in FIG. 1), a second power switch tube 52 (i.e., switch tube Q1 in FIG. 1), and a third power switch tube 53 (i.e., switch tube Q2 in FIG. 1), both of which are initially in an OFF state. 52 (i.e., Q2 in Figure 1), the third power switch tube 53 (hereinafter referred to as switch tube Q3) and the fourth power switch tube 54(hereinafter referred to as switch tube Q4), a control terminal of which is connected to the built-in battery via the operation button, and which is arranged so that when switch tube Q1 is turned on, the negative pole of the built-in battery is connected to both the control unit and the first power consumption circuit; The switch tube Q2 has a control terminal connected to one end of the switch tube Q1, and is arranged so that when the switch tube Q2 is turned on, the positive electrode of the built-in battery 2 is connected to both the control unit 3 and the first power consumption circuit 41; The switch tube Q3 has a control terminal connected to an external power supply via a power connector 6, and is arranged so that when the switch tube Q3 is turned on, the negative pole of the external power supply is connected to the second power consumption circuit 42; The switch tube Q4 has a control terminal connected to one end of the switch tube Q3, and is arranged so that when the switch tube Q3 is turned on, the positive pole of the external power supply is connected to both the second power consumption circuit 42 and the control unit 3; As can be seen from FIG. 1, the second power consumption circuit 42 is not connected to the positive or negative terminal of the built-in battery 2 .

[0037] Taking FIG. 1 as an example, the switch tubes Q1 and Q3 are N-type MOS tubes, and their switching characteristics are that when the gate voltage is higher than a predetermined voltage value, the switch tubes are turned on, otherwise they are in an off state; the switch tubes Q2 and Q4 are P-type MOS tubes, and their switching characteristics are that when the gate voltage is lower than a predetermined voltage value, the switch tubes are turned on, otherwise they are in an off state; The control terminal of the switch tube Q2 is connected to the positive electrode of the built-in battery 2 via the resistor R2 in FIG. 1, and the control terminal of the switch tube Q4 is connected to the positive electrode of the built-in battery 2 via the resistor R1 in FIG. 1, and the gate voltages of both are higher than the on-voltage threshold. At this time, the initial states of the switch tubes Q2 and Q4 are in the cut-off state (off state); In the initial state, the gate of the switch tube Q1 is grounded via resistor R7 and is at a low level. There are two ways to raise the gate voltage, which are explained below.

[0038] First type of means: When the surgical energy machine is disconnected from the external power supply, pressing the operation button 1 activates the built-in battery The positive pole of 2 supplies a high voltage to the gate of switch tube Q1 to turn it on, and operation button 1 can be a button that turns on the circuit when pressed by external force. When the operation button is pressed, switch tube Q1 remains in the on state, and when the operation button is released, switch tube Q1 changes from the on state to the off state. In this way, when medical staff in the equipment department inquire about the remaining number of available times, they can press and hold operation button 1 for a sufficient time to record the corresponding inquiry result. Alternatively, after pressing the operation button, the control unit can delay a certain period of time (e.g., 10 seconds) and then send a low level to the control terminal of switch tube Q1 to change switch tube Q1 from the on state to the off state. In this case, a separate timer electrically connected to the control unit is required, but there is no need to keep pressing the operation button manually.

[0039] The second method: when the surgical energy machine is connected to an external power source, the gate voltage of switch tube Q3 is first pulled up by the connection from the external power source, and after switch tube Q3 is turned on, the gate of switch tube Q4 is grounded through the turned-on switch tube Q3, that is, when the gate voltage of switch tube Q4 is pulled down, switch tube Q4 is subsequently turned on; furthermore, when the external power source pulls up the gate voltage of switch tube Q1 through the turned-on switch tube Q4 and resistors (see R8 and R6 in FIG. 1), switch tube Q1 is turned on.

[0040] When the switch tube Q1 turns on, the gate voltage of the switch tube Q2 is pulled down and turns on.

[0041] The trigger-on relationship between the power switch tubes of the above-mentioned switching circuit will be explained in detail below.

[0042] When the built-in battery is supplied with power from the switch tubes Q4-Q1, only the low-power consumption circuit can be triggered to operate by the operation button 1, but the amplifier circuit of the energy generator does not consume power (does not operate), and the status parameters of the device can be checked in a short time. Furthermore, since the high-power consumption circuit is not connected, there is no excessive loss in the battery, and there is no need to frequently replace the battery during the device's life cycle (in the case of a non-rechargeable battery), the battery life is extended, and even a small-capacity battery can meet the demand. When powered by an external power source, all circuits (including the high-power consumption circuit and the low-power consumption circuit) can consume power (enter the operating state).

[0043] That is, when the surgical energy machine is disconnected from the external power supply, pressing the operating button 1 will trigger the built-in battery to turn on the switch tube Q1, which in turn triggers the switch tube Q2 to turn on, putting the control unit and the first power consumption circuit 41 into an active state. At this time, the control unit will transmit the preset device status parameters to the first power consumption circuit 41, and the first power consumption circuit 41 will perform an indication operation. Please refer to the description of the related solutions such as a display, speaker, or indicator light mentioned above, and they will not be described again here.

[0044] When the surgical energy machine is connected to an external power supply, the gate voltage of switch tube Q3 is pulled up by the external power supply, turning on switch tube Q3. The turning on of switch tube Q3 further triggers switch tube Q4 to turn on, connecting the positive pole of the external power supply to the VCC terminals of control unit 3, second power consumption circuit 42, and first power consumption circuit 41. As described above, the turning on of switch tube Q4 triggers switch tube Q1 to turn on, connecting the negative pole of the external power supply to the VSS terminals of first power consumption circuit 41 and control unit 3 (ground), and at this time, unit 3, second power consumption circuit 42, and first power consumption circuit 41 are all controlled to enter an active state.

[0045] 1, the control unit 3 is also connected to the gate of the switch tube Q3. In response to the connection of the built-in battery or external power supply, the control unit detects the gate voltage of the switch tube Q3 and determines from the gate voltage of the switch tube Q3 whether the power connector 6 is connected to an external power supply. Specifically, a high level at the gate pin of switch tube Q3 indicates that the machine is currently powered by an external power supply, and a low level indicates that the machine is currently powered by the built-in battery. The present invention does not limit the specific built-in location of the built-in battery.

[0046] The control unit 3 is also connected to the gate of the switch tube Q1, and determines whether the operating button 1 is pressed based on the change in the gate voltage of the switch tube Q1. Specifically, based on the above, it is determined that the power is supplied from an external power source or the built-in battery. When the built-in battery supplies power, the gate pin level of the switch tube Q1 changes from low to high, indicating that the operating button 1 is currently pressed; when the power is supplied from an external power source, the gate level of the switch tube Q1 increases further, indicating that the operating button 1 is currently pressed.

[0047] There are two different embodiments of the operation button: The first type of method: the operation button is a dedicated button for controlling and activating the first power consumption circuit, i.e., a new button is added based on the operation button of a conventional surgical energy machine; Second type: There is no need to add a new button based on the operation button of the conventional surgical energy machine. One or more conventional function buttons can be selected as the activation button to trigger the activation of the first power consumption circuit 41. In this method, the operation button (selected function button) has a first operation mode and a second operation mode. When the surgical energy machine is disconnected from the external power source, the control unit controls the function button to operate in the first operation mode, i.e., when the function button is pressed, it triggers the switch tube Q1 to turn on. When the surgical energy machine is connected to the external power source, the control unit controls the function button to operate in the second operation mode, i.e., when the function button is pressed, it turns on the functions other than triggering the switch tube Q1 to turn on. Specifically, the functions other than triggering the switch tube Q1 to turn on include any one of the following functions: The function button is a trigger button, and when the trigger button is pressed, an energy generator of the surgical energy machine is triggered to generate energy; the function button is a power level button, and when the power level button is pressed, the output power of an energy generator of the surgical energy machine is adjusted; or The function button is a cutter head control button, and when the cutter head control button is pressed, the cutter end of the surgical energy machine performs a clamping operation. The present invention does not limit the selection range to the trigger button, the power level button, and the cutter head control button, and any existing function button of a conventional energy machine can be selected and can have the first and second operation modes.

[0048] In one embodiment of the present invention, the built-in battery is a rechargeable battery, and when the surgical energy machine is connected to an external power source, the rechargeable battery communicates with the external power source through the switch tube Q4. Specifically, as described above, in response to the surgical energy machine being connected to an external power source, the switch tube Q3 is turned on, and then the switch tubes Q4, Q1, and Q2 are turned on sequentially. At this time, the external power source can charge the rechargeable battery through the switch tubes Q4 and Q2 that are turned on.

[0049] The present invention is not specifically limited to the surgical energy machine, and in one embodiment of the present invention, the surgical energy machine is an ultrasonic knife, an electric knife, or a laser knife.

[0050] It should be explained that, in this specification, relational terms such as "first" and "second," etc., are used merely to distinguish one entity or operation from another, and do not require or imply the existence of any such actual relationship or order between those entities or operations. Furthermore, the term "comprises," or any other variation thereof, is meant to cover a non-exclusive inclusion, whereby a process, method, article, or device that includes a set of elements not only includes those elements, but also includes other elements not expressly listed or elements inherent in such process, method, article, or device. Absent more limitations, elements qualified by the phrase "comprises ..." do not exclude the presence of additional elements in the process, method, article, or device that includes the elements.
