[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0041] To address the issues of high energy consumption and noise during the heat dissipation process of energy surgical devices, this invention optimizes heat dissipation efficiency by means of partitioned heat dissipation and adjusting the output power of the heat dissipation device, thereby reducing energy consumption and noise. The following are some detailed examples.

[0042] The energy surgery device provided by this invention, such as Figure 1 As shown, it includes at least two functional modules 10 and a heat dissipation system 20.

[0043] Functional module 10 is used to perform at least one function, and heat is generated in the process of performing the at least one function.

[0044] The heat dissipation system 20 is used to dissipate heat from each functional module 10 separately. That is, since each functional module 10 is located in a different area, heat dissipation is performed on these areas separately. Since the heat generation of each functional module 10 may be different, and the working time periods or periods of heavy workload may not overlap or completely overlap, separate heat dissipation is more effective, thereby reducing noise.

[0045] like Figure 2 As shown, the heat dissipation system 20 includes at least two temperature sensors 210, a control device 230, and at least two heat dissipation devices 230. Each temperature sensor 210 is connected to the control device 230 to output temperature to the control device 230. The control device 230 is connected to each heat dissipation device 230 to control each heat dissipation device 230.

[0046] Specifically, temperature control zones can be divided for each functional module 10. For example, the area where one functional module 10 is located is a temperature control zone. Each temperature control zone is equipped with at least one temperature sensor 210 and at least one heat dissipation device 230. That is, each temperature sensor 210 is located in the temperature control zone where each functional module 10 is located. The temperature sensor 210 is used to detect the temperature value of its respective temperature control zone. The temperature sensor 210 can be any type of temperature sensor; this embodiment uses a thermocouple as an example for explanation.

[0047] Similarly, each heat dissipation device 230 is located in a specific temperature control zone (hereinafter referred to as the temperature zone). The heat dissipation device 230 is used to dissipate heat from its respective temperature control zone. The heat dissipation method of the heat dissipation device 230 is not limited, and can include air cooling, liquid cooling, heat conduction, etc. Considering the characteristics and size of the equipment, this embodiment adopts a heat sink + air cooling approach, which offers high cost-effectiveness. Specifically, in this embodiment, the heat dissipation device 230 includes a fan. The number of fans within the same temperature control zone is not limited and depends on the area of ​​the temperature zone, typically one or two fans.

[0048] As can be seen, this invention divides the energy surgery device into different areas according to different functional modules, and provides heat dissipation for each area separately. Since the various functional modules of the energy surgery device are usually not in continuous operation during the operation process, and their heat generation is usually different, heat dissipation by area is more targeted, which can reduce the overall heat dissipation power consumption and thus reduce the overall noise.

[0049] The control device 230 is used to acquire the temperature value of the temperature control zone detected by each temperature sensor 210, and adjust the output power of the heat dissipation device 230 in the corresponding temperature control zone (that is, the temperature zone where the temperature sensor is located) based on the temperature value. The output power of the heat dissipation device is adjustable, which makes it convenient to increase the output power only when greater heat dissipation is required, and can further optimize heat dissipation, energy consumption, noise and the life of the heat dissipation system.

[0050] like Figure 3 As shown, the energy surgery device includes at least two functional modules 10, which can be at least two of the following: a power supply circuit 11, a boost circuit 12, an inverter circuit 13, and a sampling and processing circuit 14. This embodiment uses the energy surgery device including these four types as an example for illustration. The power supply circuit 11 is connected to the inverter circuit 13 through the boost circuit 12.

[0051] The power supply circuit 11 performs at least one function, which may include converting external alternating current (AC) into stable direct current (DC) to power the energy surgical device. The power supply circuit 11 may, for example, be a switching power supply, with a corresponding temperature range of... Figure 2 The middle section is the main power supply temperature zone.

[0052] The boost circuit 12 performs at least one function, which may include: boosting the DC power output from the power supply circuit 11 to provide a reference voltage level for subsequent drive devices, facilitating later control. Its corresponding temperature range is... Figure 2 The middle section is the pressure-boosting temperature zone.

[0053] The inverter circuit 13 performs at least one function, which may include: inverting boosted DC power into frequency-modulated output energy, such as high-frequency pulses. Different energy surgical devices may have different inversion frequencies; for example, energy surgical devices include high-frequency surgical devices, radiofrequency surgical devices, plasma surgical devices, and ultrasonic surgical devices. For high-frequency surgical devices, such as high-frequency electrosurgical units, the inverted frequency can be around 1.4MHz. For plasma surgical devices, the inverted frequency can be around 100kHz. For ultrasonic surgical devices, the inverted frequency can be around 20-50kHz. The corresponding temperature range is... Figure 2 The middle is the inverter temperature zone.

[0054] The energy-powered surgical device may further include a voltage transformer for acquiring voltage values ​​at the surgical site and a current transformer for acquiring current values ​​at the surgical site. The sampling and processing circuit 14 performs at least one function, which may include: acquiring the voltage values ​​acquired by the voltage transformer and the current values ​​acquired by the current transformer; using the voltage and current values ​​to calculate the real-time impedance of the surgical site; and / or to calculate the phase difference between the voltage and current at the surgical site. This facilitates the energy-powered surgical device in adjusting the energy release process based on the real-time impedance and / or phase difference. The sampling and processing circuit 14 mainly includes an FPGA (Field-Programmable Gate Array), meaning its functions are implemented by an FPGA, and the corresponding temperature range is... Figure 2 The middle section represents the FPGA temperature range.

[0055] In some embodiments, for a temperature control zone, if the temperature has not reached the warning condition, the heat dissipation device 230 can be controlled to operate at a relatively low output power. That is, during operation of any functional module 10 within the temperature control zone, if the heat generated is not significant, the fan operates at a lower speed to reduce energy consumption and noise. Conversely, if the temperature of the temperature control zone reaches the warning condition, meaning the functional module 10 generates a relatively large amount of heat, the fan operates at a higher speed to increase heat dissipation. This means that each temperature control zone has at least two temperature states: one where the warning condition has not been reached, and another where the warning condition has been reached. The heat dissipation device then has at least two output power levels: a low power level and a high power level. When the warning condition is reached, the output power of the heat dissipation device is higher (corresponding to a faster fan speed). Specifically, this function of the control device 220 can be comprised of… Figure 4 The circuit shown is used to implement this, and will be explained in detail below.

[0056] like Figure 4 As shown, the control device 220 may include an analog-to-digital converter circuit 221, a controller 222, and a drive circuit 223.

[0057] The number of analog-to-digital converter circuits 221 is the same as that of temperature sensors 210, with one analog-to-digital converter circuit 221 connected to one temperature sensor 210. The analog-to-digital converter circuit 221 is used to convert the analog signal of the temperature value output by the temperature sensor 210 into a digital signal of the temperature value.

[0058] like Figure 5 As shown, in one embodiment, the analog-to-digital conversion circuit 221 may include an analog-to-digital conversion chip U1, a first capacitor C1, and a transformer U.

[0059] The ground terminal GND of the analog-to-digital converter chip U1, the negative output terminal T- of the analog-to-digital converter chip U1, one end of the first capacitor C1, and one end of the primary winding of the transformer U are all grounded. The positive output terminal T+ of the analog-to-digital converter chip U1 is connected to the other end of the first capacitor C1 and one end of the other winding of the transformer U. The other ends of the primary winding and the other winding of the transformer U are respectively connected to the two input terminals of the controller. In this embodiment, the analog-to-digital converter chip U1 can be a MAX6675ISA chip, but other chips that can perform analog-to-digital conversion can also be used.

[0060] The number of drive circuits 223 and heat dissipation devices 230 is the same. One drive circuit 223 is connected to a heat dissipation device 230 in a temperature control area and is used to drive the heat dissipation device 230 connected to it.

[0061] The controller 222 has multiple input terminals, which are connected to various analog-to-digital converter circuits 221. The controller 222 also has multiple output terminals, which are connected to various drive circuits 223.

[0062] The controller 222 acquires digital signals of temperature values ​​converted by the analog-to-digital converter 221. A portion of these digital temperature signals triggers the controller 222 to output a first temperature control parameter to the drive circuit 223 connected to the heat dissipation device 230 in the corresponding temperature control area. Another portion of the digital temperature signals triggers the controller 222 to output a second temperature control parameter to the drive circuit 223 connected to the heat dissipation device 230 in the corresponding temperature control area. In other words, the controller 222 can output the first temperature control parameter to the drive circuit 223 connected to the heat dissipation device 230 in the temperature control area when the temperature in the temperature control area reaches the corresponding warning condition; and it can output the second temperature control parameter to the drive circuit 223 connected to the heat dissipation device 230 in the temperature control area when the temperature in the temperature control area does not reach the corresponding warning condition. Warning conditions include a temperature rise rate exceeding a speed threshold, or a temperature value exceeding a temperature threshold. Specifically, a portion of the digital temperature signals includes signals indicating a temperature rise rate exceeding a speed threshold, or a temperature value exceeding a temperature threshold; the other portion includes signals indicating a temperature rise rate not exceeding a speed threshold, or a temperature value not exceeding a temperature threshold.

[0063] The drive circuit 223 receives temperature control parameters output by the controller 222, converts these parameters into a PWM control signal, and then drives the heat dissipation device to operate. The output power (e.g., fan speed) of the heat dissipation device controlled by the PWM control signal converted from the first temperature control parameter is higher than the output power controlled by the PWM control signal converted from the second temperature control parameter. The PWM control signal converted from the first temperature control parameter can be used to drive the fan to increase its speed, for example, by increasing the fan speed until the temperature in the temperature control zone no longer rises, or by driving the fan to operate at its maximum speed. The PWM control signal can specifically adjust the PWM waveform of the voltage and / or current of the heat dissipation device, thereby adjusting the output power of the heat dissipation device.

[0064] The control device 220 may also include a memory 224. The memory 224 may be used to store the warning conditions (such as speed threshold, temperature threshold, etc.) corresponding to each temperature control zone, the first temperature control parameter (such as the temperature to be controlled or the fan speed) corresponding to the achievement of the warning condition, and the second temperature control parameter (such as the temperature to be controlled or the fan speed) corresponding to the failure to achieve the warning condition. Specifically, this function may be implemented using a memory chip.

[0065] The controller 222 is also connected to the memory 224 and can retrieve speed thresholds, temperature thresholds, and temperature control parameters from the memory 224. The warning conditions corresponding to each temperature control zone can be the same or different; this embodiment uses the latter as an example, meaning that at least two temperature control zones in this embodiment have different speed or temperature thresholds. This allows for adaptive adjustment of the fan speed according to different functional modules, making heat dissipation more targeted. The controller 222 can determine whether the rate of temperature increase exceeds the speed threshold or whether the temperature exceeds the temperature threshold based on the temperature value of the temperature control zone. If it exceeds, the warning condition is met; otherwise, the warning condition is not met. The controller then outputs the corresponding temperature control parameters from the memory to the drive circuit 223 corresponding to the temperature control zone. This implementation process of the controller 222 does not require complex logic processing and can be achieved using conventional methods. The controller 222 can use a microcontroller chip such as the STM32F103; however, this is just an example, and other chips capable of achieving the above functions can also be used. Of course, the controller 222 can also be implemented using pure hardware circuits, such as comparators and switching elements. The comparator is used to compare the voltage corresponding to the temperature value with a preset voltage, thereby determining whether the temperature value has reached the warning condition. The switching element is used to control the drive circuit 223; for example, the switching element can be a trigger, used to output instructions corresponding to different temperature control parameters to the drive circuit 223 when triggered by the comparison result output by the comparator. In fact, the control chip is a large-scale integrated circuit, and its function is ultimately implemented through circuits.

[0066] The first temperature control parameters for each temperature control zone can be the same, or the differences in heat generation of the functional module 10 can be taken into account, allowing the first temperature control parameters for each temperature control zone to be different. This embodiment will use the latter as an example, that is, when the temperature values ​​of at least two temperature control zones reach the warning condition, their fan speeds are different, which can better adapt to the heat generation of the functional module 10.

[0067] like Figure 5 As shown, the drive circuit 223 may include a drive chip U2, a second capacitor C2, and a first resistor R1. The common terminal COM of the drive chip U2 receives DC power (e.g., 5V DC) and is connected to the ground terminal GND of the drive chip U2 through the second capacitor C2. The ground terminal GND of the drive chip U2 is grounded. The first output terminal OUT1 of the drive chip U2 is connected to the fan and is also connected to the fan's power supply terminal (e.g., 5V DC) through the first resistor R1. In this embodiment, the drive chip U2 can be a ULN2003 chip; however, other chips capable of performing drive functions can also be used.

[0068] The energy surgery device may also include an alarm connected to the controller 222, which emits an audible, visual, or electrical signal to alert the user when the temperature value in the temperature control zone reaches a warning condition. An alarm, such as an alarm indicator light, can be installed in each temperature control zone to allow the user to monitor the temperature status of each zone at any time.

[0069] Energy surgical devices, such as high-frequency surgical devices, are intermittently operating devices, so they cannot operate continuously. Therefore, the temperature of each operating zone changes flexibly during operation. The heat dissipation system provided by this utility model can reduce the time that the fan is in a high-speed rotation state for a long time, thereby reducing its own wear and tear, overall power consumption, and extending its life. It can also effectively reduce the overall noise of the fan, making the working prompts of the device during the operation easier to recognize.

[0070] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
