Description

Technical Field

[0001] The present invention relates to the field of high-end medical devices, and in particular to an energy output device, method, storage medium and operating system. Background Art

[0002] In the medical device field, energy delivery devices, such as ultrasonic surgical instruments, electro-energy surgical instruments, and laser surgical instruments, have been widely used in various surgical procedures. These devices deliver energy to the patient's tissue, achieving therapeutic effects such as tissue cutting, hemostasis, or healing. During surgery, doctors typically need to clamp the target tissue and deliver energy. Traditional methods often require doctors to rely on their own experience, using their eyes and hands to determine whether the clamping force is appropriate to ensure the device's output is effective and effective.

[0003] However, in existing technologies, the need for doctors to simultaneously clamp and press buttons can cause hand deformation, leading to ineffective clamping and, in turn, impacting surgical outcomes. Specifically, doctors often manually activate the device's energy output after determining whether clamping is successful. During this process, the clamping and button-pressing actions can conflict, making it impossible to maintain a stable clamping force, ultimately impacting the device's output and treatment outcomes.

[0004] Therefore, how to improve the operation method in the existing technology to avoid clamping failure due to improper hand movements and ensure that the energy output device can perform treatment more efficiently and accurately has become an urgent problem to be solved. Summary of the Invention

[0069] Figure 1 A structural block diagram of an energy output device according to an embodiment of the present invention is shown as follows: Figure 1 As shown, the energy output device 100 includes:

[0070] The first sensor 101 is used to detect the clamping pressure value when the user clamps;

[0071] The second sensor 102 is used to detect the temperature of the user contact surface;

[0072] A signal processing unit 103 is connected to the first sensor 101 and the second sensor 102, and is used to determine that the user's clamping of the target tissue is effective if the clamping pressure value detected by the first sensor 101 and the temperature value of the user contact surface of the second sensor 102 both meet set conditions;

[0073] The energy output unit 104 is connected to the signal processing unit 103 and is used to output energy to the target tissue if the user's grip on the target tissue is effective.

[0074] Specifically, the energy output device provided in this application includes a first sensor 101 and a second sensor 102. The first sensor 101 is used to detect the clamping pressure applied by the user during clamping, while the second sensor 102 is used to detect the temperature of the contact surface. When the clamping pressure detected by the first sensor 101 reaches or exceeds a preset value (e.g., greater than or equal to 15N), and the contact surface temperature detected by the second sensor 102 is greater than or equal to the standard human body temperature (36-37°C) and significantly higher than the ambient temperature (e.g., 20°C), the system automatically determines that the clamping is effective. This energy output device can effectively distinguish whether the user has successfully contacted the target tissue, avoiding ineffective treatment or damage caused by improper contact.

[0075] The technical solution of the present application can significantly improve the automation level of the equipment and the accuracy of the surgery. When the clamping is effective, the signal processing unit 103 will trigger the energy output unit 104 to output energy of appropriate intensity to the target tissue for treatment. This process of automatic judgment and energy output avoids false triggering or misoperation that may be caused by manual operation of the doctor, effectively reduces the doctor's operating burden, and improves the success rate and safety of the operation. In addition, when the system detects that the clamping is invalid (such as insufficient pressure value or temperature value below the preset standard), it will stop energy output, thereby ensuring that treatment is only performed under correct clamping, reducing potential treatment risks. Through this intelligent operation, the present application can improve the reliability, accuracy and safety of medical equipment, and has broad application prospects.

[0076] In one embodiment, the signal processing unit 103 is used to determine that the user's clamping state of the target tissue is a valid state when the first sensor 101 detects that the effective value of the clamping pressure value is greater than or equal to a preset pressure value and the second sensor 102 detects that the temperature value of the user contact surface is greater than or equal to a preset temperature value.

[0077] Specifically, the signal processing unit 103 first receives and processes the clamping pressure signal from the first sensor 101 and the temperature signal from the second sensor 102, and compares these two signals with preset standard values. The signal processing unit 103 considers the clamping state to be valid when the following conditions are met:

[0078] The effective clamping pressure detected by the first sensor 101 must be greater than or equal to a preset pressure value. This pressure value is set based on the physical properties of the target tissue and the treatment requirements. Generally, this preset pressure value is adjusted based on different surgical scenarios and treatment needs. For example, for soft tissue, the pressure value may be set between 15N and 30N. By setting this pressure condition, the system ensures that the user's clamping force is sufficient to effectively secure the target tissue and provide a stable foundation for energy output. The contact surface temperature detected by the second sensor 102 must be greater than or equal to a preset temperature value. Since the target tissue generally matches the internal temperature of the human body, changes in the contact surface temperature can reflect whether effective contact has been established with the living tissue. In a common embodiment, the normal human body temperature ranges from 36°C to 37°C, while the ambient temperature is generally around 20°C. When the temperature detected by the second sensor 102 is greater than or equal to a preset standard temperature value (e.g., 36°C) and higher than the ambient temperature, it indicates that the sensor has successfully contacted the target tissue. This temperature detection can effectively distinguish between poor contact and avoid false positives caused by low temperature signals. By simultaneously satisfying these two conditions, the signal processing unit 103 determines that the user's grip on the target tissue is valid. Once the grip is confirmed to be valid, the signal processing unit 103 sends a signal to the energy output unit 104, triggering energy output and initiating the treatment. This process not only ensures treatment accuracy but also automatically avoids treatment risks associated with improper grip or incomplete contact.

[0079] This embodiment significantly enhances the intelligence and safety of the energy delivery device by integrating multiple pressure and temperature detection mechanisms. This intelligent judgment process reduces the operator's reliance on judgment, lowering the risk of human error. It also ensures that energy delivery occurs only when clamping and contact conditions meet standards, further improving the success rate and safety of surgical treatments.

[0080] In one embodiment, the signal processing unit 103 is used to determine that the user's clamping state of the target tissue is invalid when the first sensor 101 detects that the effective value of the clamping pressure value is less than a preset pressure value or when the second sensor 102 detects that the temperature value of the user contact surface is less than a preset temperature value.

[0081] Specifically, when the signals detected by the first sensor 101 and the second sensor 102 do not meet preset criteria, the signal processing unit 103 determines that the user's grip on the target tissue is invalid and takes appropriate measures to prevent energy delivery. When the effective clamping pressure detected by the first sensor 101 is less than a preset pressure value, the signal processing unit 103 determines that the grip is invalid. The preset pressure value is set based on the physical properties of the target tissue, surgical requirements, and treatment objectives. If the pressure value is insufficient, the clamping force is insufficient and the target tissue cannot be effectively secured, making the treatment effect difficult to guarantee. For example, if the pressure value is less than 15N, the clamping is unstable, which can easily lead to inaccurate treatment or tissue damage. In this case, to avoid operational errors or surgical risks, the signal processing unit 103 determines that the grip is invalid and stops energy delivery. If the temperature of the user's contact surface detected by the second sensor 102 is less than a preset temperature value, the signal processing unit 103 also determines that the grip is invalid. Under normal circumstances, the human body's contact temperature range should be between 36°C and 37°C, while the ambient temperature is typically around 20°C. If the second sensor 102 detects a contact surface temperature below a preset reference temperature (e.g., below 36°C), this indicates incomplete contact or a failure to establish contact with the target tissue. This low temperature signal suggests the sensor may be in the wrong contact position or poor contact with the target tissue. To prevent treatment failure or injury caused by erroneous energy delivery, the signal processing unit 103 determines that clamping is invalid, ensuring energy delivery only when effective contact is established.

[0082] Figure 2 A structural block diagram of an energy output device according to another embodiment of the present invention is shown as follows: Figure 2 As shown, the energy output device 200 includes a handle unit 105, on which the first and second sensors 101, 102 are mounted; and a signal source unit 106, which includes a square wave generator 109, a signal shaping unit 110, a first isolation transformer 107, and a second isolation transformer 108. The square wave generator and signal shaping unit are used to convert square wave signals into sinusoidal signals and provide them to the handle unit 105.

[0083] The first sensor 101 is connected to the first isolation transformer 107.

[0084] The second sensor 102 is connected to the second isolation transformer 108.

[0085] The first isolation transformer 107 and the second isolation transformer 108 are used for electrical isolation and signal transmission between the signal source unit 106 and the handle unit 105 .

[0086] Specifically, the handle unit 105 is an operating device of the device, and the user performs a clamping operation on the target tissue through the handle unit 105. The first sensor 101 and the second sensor 102 are respectively provided on the handle unit 105, and they work together to sense the effectiveness of clamping.

[0087] The signal source unit's primary function is to generate and shape signals suitable for transmission by the handle unit 105. The square wave generator uses the microcontroller's PWM (pulse width modulation) module to generate a square wave signal, typically at a specific frequency (e.g., 10 kHz), which serves as the system's basic signal source. This signal is subsequently converted into a sinusoidal signal to meet the sensor's operating requirements. The signal shaping unit converts the square wave signal into a sinusoidal signal. While square waves are easy to generate, they contain significant high-frequency noise, while sinusoidal signals are smoother and more suitable for sensor data processing. By using components such as capacitors and resistors, the signal shaping unit effectively removes noise and shapes the signal into a stable sinusoidal wave, which is then transmitted to the handle unit 105 for measurement and processing. The first isolation transformer 107 and the second isolation transformer 108 provide electrical isolation and signal transmission between the signal source unit and the handle unit 105. Electrical isolation between the signal source unit and the handle unit 105 is crucial because it prevents damage or malfunction caused by electrical faults or high voltages. The transformers transmit signals through electromagnetic induction, avoiding the electrical interference that can arise from direct connections. The first isolation transformer 107 and the second isolation transformer 108 are responsible for transmitting the signals from the pressure sensor and the temperature sensor to the signal source unit respectively, while maintaining electrical isolation to ensure safe and stable operation of the system.

[0088] The main function of the first isolation transformer 107 and the second isolation transformer 108 is to achieve electrical isolation between the signal source unit and the handle unit 105. These transformers use electromagnetic induction to transmit signals, thereby avoiding problems caused by direct electrical connection, such as current reversal or voltage fluctuations. Specifically, when the sensor in the handle unit 105 obtains a pressure signal or a temperature signal, these signals will be transmitted through the corresponding isolation transformer to ensure that the quality of the signal during the transmission process is not affected by electrical interference. Another important function of the first isolation transformer 107 and the second isolation transformer 108 is to provide protection in the event of a system failure. When a short circuit or failure occurs in the sensor or related circuit of the handle unit 105, the isolation transformer can effectively prevent high voltage or noise signals from being fed back to the signal source unit, thereby avoiding damage to the equipment. Through this design, the present application ensures that the equipment can still work stably and reliably in a complex surgical environment, reducing potential safety hazards caused by electrical failures.

[0089] In one embodiment, at least two electrodes are provided inside the first sensor. When the user clamps the handle unit 105, the at least two electrodes are short-circuited, and the impedance of the secondary of the first isolation transformer 107 changes from no-load to short-circuit; the equivalent impedance of the primary of the first isolation transformer 107 will also become extremely small, and the effective value of the current signal at the first detection point will become smaller; when the signal of the first detection point is collected by the single-chip microcomputer and the effective value of the current is calculated to be less than the first set current, it is determined that the effective value of the clamping pressure value is greater than or equal to the preset pressure value.

[0090] In one embodiment, when the user releases the clamping handle unit 105, the first sensor 101 returns to normal state, the secondary impedance of the first isolation transformer 107 returns to no-load, the equivalent impedance of the primary of the first isolation transformer 107 will also become extremely large, and the effective value of the signal at the first detection point becomes larger. The single-chip microcomputer collects the signal at the first detection point and calculates that the effective value of the current value at the first detection point is greater than or equal to the first set current, and determines that the effective value of the clamping pressure value is less than the preset pressure value.

[0091] The present application adopts a pressure sensor design with at least two electrodes, which can detect the clamping state in real time and accurately, and automatically trigger energy output when the pressure meets the preset standard. This intelligent detection method avoids the mistakes of traditional manual operation and reduces the potential risks caused by insufficient clamping, excessive clamping force or too little clamping force. The electrical isolation design of the electrode short-circuit triggering mechanism and the isolation transformer can ensure the stability and security of the data during signal transmission. In addition, when the user relaxes the clamping handle unit 105, the first sensor 101 will return to normal, the secondary impedance of the first isolation transformer 107 will return to no-load, the effective value of the signal at the first detection point will increase, the single-chip microcomputer will collect the signal again and determine whether the clamping pressure value is less than the preset pressure value, thereby automatically stopping the energy output. This ensures that the device will only perform treatment when the clamping is effective, further ensuring the safety of the patient.

[0092] In one embodiment, when the user clamps the handle unit 105, the impedance of the second sensor 102 is greater than that at room temperature, the secondary impedance of the second isolation transformer 108 becomes larger, and the equivalent impedance of the primary of the second isolation transformer 108 will also become larger, and the effective value of the signal detected at the second signal point will increase; when the signal at the second signal point is collected by the single-chip microcomputer and the corresponding signal current value is calculated to be greater than or equal to the second set current value, it is determined that the temperature value of the target tissue detected by the second sensor 102 is greater than or equal to the preset temperature value.

[0093] In one embodiment, when the user releases the grip on the handle unit 105, the ambient temperature of the second sensor 102 reaches room temperature, the impedance of the thin film sensor is smaller than when there is tissue, the secondary impedance of the second isolation transformer 108 decreases, the equivalent impedance of the primary also decreases, and the effective value of the signal at the second signal detection point decreases.

[0094] When the single chip microcomputer collects the signal at the second signal point and calculates that the corresponding signal current value is less than the second set current value, it is determined that the temperature value of the target tissue detected by the second sensor 102 is less than the preset temperature value.

[0095] By introducing the second sensor 102 and using it in conjunction with the second isolation transformer 108, the system can automatically monitor the effectiveness of clamping during surgery and determine the accuracy of contact based on temperature changes. Specifically, the system determines effective contact with the target tissue by detecting temperature changes in real time. When clamping is effective, it triggers energy delivery. This not only improves the accuracy of energy delivery but also reduces the risk of misoperation and treatment failure.

[0096] In one embodiment, the energy output unit 104 is configured to output energy of different intensities to the target tissue according to the user clamping pressure value detected by the first sensor 101 and the user temperature value and the ambient temperature value detected by the second sensor 102 .

[0097] In one embodiment, the signal processing unit 103 is further configured to set different clamping pressure values detected by the first sensor 101 and target tissue temperature values detected by the second sensor 102 according to different users to adapt to different users.

[0098] Specifically, through an intelligent signal processing mechanism, the intensity of energy output can be dynamically adjusted according to the real-time data from the first sensor 101 and the second sensor 102, thereby ensuring the accuracy and safety of the treatment. When the detection data of the first sensor 101 and the second sensor 102 simultaneously meet the preset conditions, the energy output unit 104 will be activated and output energy of appropriate intensity. This adjustment process is based on real-time data and can flexibly respond to changes in clamping force and temperature. For example, when the clamping pressure is high, the system can output higher intensity energy for treatment; when the clamping pressure is low, the system will automatically reduce the energy output to ensure accuracy and safety during the treatment process. Through this intelligent adjustment, the energy output unit 104 not only improves the automation level of the equipment, but also effectively avoids misoperation caused by improper clamping, ensuring the efficiency of treatment and the safety of patients.

[0099] In one embodiment, the first sensor 101 includes but is not limited to a thin film pressure sensor, which detects the clamping pressure signal when the user clamps; and determines the clamping pressure value based on the pressure signal. Specifically, the first sensor 101 includes but is not limited to a thin film pressure sensor, which is used to detect in real time the clamping pressure signal applied by the user when clamping. The thin film pressure sensor senses the pressure changes applied to the target tissue, converts it into an electrical signal, and provides it to the signal processing unit 103. The signal processing unit 103 determines the clamping pressure value based on the received pressure signal. The pressure value is used to determine whether the clamping force of the user meets the preset standard, ensure that the clamping is firm and effectively fixes the target tissue, and provide accurate basic data for subsequent treatment operations.

[0100] In one embodiment, the second sensor 102 includes but is not limited to a thin film temperature sensor, which detects the impedance value of the target tissue when clamped by the user, and determines the temperature value of the target tissue based on the impedance value. Specifically, the second sensor 102 includes but is not limited to a thin film temperature sensor, which is used to detect the contact surface temperature of the target tissue when clamped by the user. The thin film temperature sensor indirectly obtains temperature information by measuring the impedance change of the contact part with the target tissue. Since the temperature of living tissue is usually high and the ambient temperature is low, the impedance of the sensor will change with the temperature change. The signal processing unit 103 calculates and determines the temperature value of the target tissue based on the impedance value measured by the sensor. The change in temperature value can reflect whether the contact is sufficient, help determine whether effective contact is established with the target tissue, and thus provide an important basis for the effectiveness of energy output.

[0101] In an embodiment of the present invention, a calculation method for a thin film pressure sensor involves real-time monitoring of changes in the sensor's resistance characteristics when pressure is applied to a clamp. Typically, before surgery, the clamp's clamping force on the blood vessel should be controlled between 15 and 30 N to ensure stable clamping and accurate treatment. To accurately detect the clamping state, the thin film pressure sensor in the clamp senses the applied clamping pressure and changes its resistance characteristics based on the pressure change. Specifically, as pressure increases, the resistance of the thin film pressure sensor decreases. This change is achieved by changes in the resistance characteristics of the sensor material. When the clamping force reaches 15 N, the resistance of the thin film pressure sensor drops significantly, falling below 10 ohms. This change is due to the sensor material's response to pressure. When the sensor resistance decreases to 10 ohms, the resistance of the transformer's secondary winding is approximately 100 ohms, and the AC current flowing through the secondary winding is approximately 10 mA. Since the transformer's primary-to-secondary winding ratio is 2:1, changes in the secondary winding current cause changes in the primary winding current, resulting in a primary winding current of 5 mA. Due to the internal resistance of the primary winding circuit (approximately 200 ohms), the RMS voltage at the primary winding acquisition point increases, reaching 1V. This allows the system to determine the clamping status based on changes in the voltage signal. When the RMS voltage of the primary winding reaches or exceeds 1V, the microcontroller acquires and analyzes the signal. At this point, the threshold is set to 1V, which determines that the clamp has effectively grasped the vessel. Once this determination is triggered, the system enters energy delivery mode and begins the corresponding treatment. This method accurately detects the clamping status and provides a direct feedback mechanism based on changes in the voltage signal, ensuring that energy delivery is only initiated when the clamping strength meets the preset standard. This approach avoids treatment failures caused by insufficient or unstable clamping, improving the accuracy and safety of the treatment process.

[0102] This application can determine whether the doctor has successfully clamped the target tissue by detecting changes in the thin film temperature and pressure sensor on the handle. When the standard is reached, the energy output device will automatically activate the output, ensuring a high success rate and achieving the best results. This method can greatly simplify the surgeon's operating steps, effectively reduce the doctor's hand fatigue, and increase the success rate of the operation. Figure 3 A schematic diagram showing the circuit structure of an energy output device according to another embodiment of the present invention is shown. Figure 3 As shown, the energy output device 200 includes a front handle unit, a signal source unit, a signal monitoring unit and an energy output unit.

[0103] Specifically, the front handle unit allows the doctor to clamp the surgical site and apply the output energy to it. The unit also contains two sensors: a thin film pressure sensor and a thin film temperature sensor. The function of the thin film pressure sensor is that when the doctor performs a clamping operation, the target tissue will produce a squeezing effect at the location of the pressure sensor, causing its internal deformation. When the predetermined pressure is reached, the two ends of the sensor are short-circuited. The thin film temperature sensor is made of platinum metal as the base material and utilizes the temperature characteristics of platinum metal (its impedance value is different at different temperatures). When living tissue contacts the sensor, the impedance value of the sensor will change significantly because the temperature of the living tissue is higher than the ambient temperature of the operating room.

[0104] The signal source unit includes a square wave generating part, usually a single-chip microcomputer, and a signal shaping part R1, C1, T1 (R2, C2, T2). The working principle is that the single-chip microcomputer sends a 10kHz square wave signal at the IO pin through the internal PWM function module, and then converts the square wave signal into a sine wave signal through the signal shaping part, and sends it to the handle unit through the secondary of the isolation transformer. The isolation transformer has two functions: first, if the handle unit fails and causes the sensor to short-circuit, the presence of the isolation transformer will not cause damage to the signal source unit; second, when energy output is carried out, it is often accompanied by high voltage. The isolation transformer can effectively isolate the high-frequency and high-voltage signal to ensure that the signal source unit circuit will not be damaged by breakdown.

[0105] The signal monitoring and energy output unit consists of a signal acquisition component, typically a single-chip microcontroller (MCU), a calculation and judgment component, also typically a single-chip microcontroller, and an energy output component. The MCU uses its internal ADC to collect the two detection signals. After a cycle time (100µs), it performs a root mean square (RMS) calculation on all data to obtain the effective value of the voltage signal. If this RMS value remains within a threshold for a certain period of time, it is determined that the target tissue is properly clamped and meets the conditions for energy output. This determination is then transmitted to the energy output component, which then performs the corresponding energy output operation.

[0106] Method for determining effective clamping: Two criteria must be met simultaneously for a clamp to be considered effective. First, when the two electrodes within the thin-film pressure sensor are short-circuited due to the compression of the clamped tissue, the secondary impedance of the isolation transformer T1 changes from no-load (maximum) to short-circuit (minimum). At this point, the equivalent impedance of the isolation transformer's primary also becomes extremely low, and the effective value of the signal at detection signal 1 is very low. At this point, the microcontroller collects and calculates the corresponding effective value of the signal, which is necessarily less than the threshold, thus determining that the signal is effective. When the doctor releases the clamp and the thin-film pressure sensor returns to normal, the secondary impedance of the isolation transformer T1 returns to no-load (maximum), and the equivalent impedance of the primary also becomes maximum. The effective value of the signal at the detection signal returns to its maximum value. The microcontroller collects and calculates the corresponding effective value of the signal, which is necessarily greater than the threshold, thus determining that the signal is invalid. Second, when the temperature of the thin-film temperature sensor is higher than the ambient temperature due to the clamped tissue, the sensor impedance increases compared to room temperature, and the secondary impedance of the isolation transformer T2 increases. At this point, the equivalent impedance of the isolation transformer's primary also increases, and the effective value of the signal at detection signal 2 increases. At this point, the corresponding signal's effective value, collected and calculated by the microcontroller, will increase. When it reaches the threshold, the signal is considered valid. When the doctor releases the clamp, the temperature surrounding the thin-film temperature sensor returns to room temperature, and the sensor's impedance decreases compared to when tissue is present. The secondary impedance of isolation transformer T2 decreases, and the equivalent impedance of the primary also decreases, causing the effective value of the signal at detection signal 2 to decrease. When the effective value of the corresponding signal collected and calculated by the microcontroller falls below the threshold, the signal is considered invalid. When both judgment signals are valid, the result is considered valid; when either signal is invalid, the result is considered invalid. When the result is valid, the energy device generates the corresponding output.

[0107] Compared with the prior art, the advantages of this application include:

[0108] 1. In existing technologies, physical buttons installed on the handle are generally used to control output, which may cause false triggering or energy output before the triggering requirements are met. In this application, energy output is only activated when the triggering conditions are truly met. This output does not require manual judgment, which greatly reduces failures or poor results caused by operator error.

[0109] 2. The device automatically determines the output conditions, which can reduce the doctor's hand fatigue and reduce the operator's workload.

[0110] 3. The detection unit is equipped with an isolation transformer, which can isolate external energy signals and effectively protect the equipment.

[0111] 4. When the handle fails, the detection unit can immediately detect the problem and stop energy output. Compared with relying on physical button control, it can protect the patient's safety more quickly and better.

[0115] Step 403 , if the clamping pressure value detected by the first sensor and the temperature value of the user contact surface detected by the second sensor both meet the set conditions, it is determined that the user's clamping of the target tissue is effective;

[0116] Step 404 : If the user's grip on the target tissue is effective, energy is output to the target tissue.

[0117] In one embodiment, when the first sensor detects that the effective value of the clamping pressure value is greater than or equal to the preset pressure value and the second sensor detects that the temperature value of the user contact surface is greater than or equal to the preset temperature value, it is determined that the user's clamping state of the target tissue is in the effective state;

[0118] In one embodiment, when the first sensor detects that the effective value of the clamping pressure value is less than a preset pressure value or when the second sensor detects that the temperature value of the user contact surface is less than a preset temperature value, it is determined that the user's clamping state of the target tissue is invalid.

[0119] In one embodiment, the clamping pressure when the user clamps is detected by at least two electrodes of the first sensor, and when the clamping pressure reaches a preset pressure, the two electrodes are short-circuited; when the two electrodes are detected to be short-circuited, it is determined that the secondary impedance of the isolation transformer has changed from the original no-load to a short circuit, and the primary equivalent impedance is correspondingly made extremely small; the current signal of the first detection signal point is collected and the effective value of the current is calculated. When the effective value of the current is less than the preset current, it is determined that the clamping pressure value is greater than or equal to the preset pressure value.

[0120] In one embodiment, when the user relaxes the clamping, the two electrodes return to normal state, the secondary impedance of the isolation transformer returns to no-load, and the primary equivalent impedance returns to maximum; the signal value of the first signal point is collected and the effective value of the current is calculated. When the effective value of the current is greater than or equal to the preset current, it is determined that the clamping pressure value is less than the preset pressure value.

[0121] In one embodiment, when the user clamps the handle unit, the impedance of the second sensor is greater than that at room temperature, the secondary impedance of the second isolation transformer becomes larger, the equivalent impedance of the primary of the second isolation transformer will also become larger, and the effective value of the signal detected at the second signal point will increase; when the signal at the second signal point is collected by the single-chip microcomputer and the corresponding signal current value is calculated to be greater than or equal to the second set current value, it is determined that the temperature value of the target tissue detected by the second sensor is greater than or equal to the preset temperature value.

[0122] In one embodiment, when the user relaxes the clamping handle unit, the temperature around the second sensor is room temperature, the impedance of the thin film sensor is smaller than when there is tissue, the secondary impedance of the second isolation transformer becomes smaller, the equivalent impedance of the primary also becomes smaller, and the effective value of the signal detected at the second signal point will decrease; when the single-chip microcomputer collects the signal at the second signal point and calculates that the corresponding signal current value is less than the second set current value, it is determined that the temperature value of the target tissue detected by the second sensor is less than the preset temperature value.
