Abstract
Description
Technical Field

[0002] In the field of medical devices, energy output devices have been widely used in various surgeries, such as ultrasonic surgical instruments, electro-energy surgical instruments, laser surgical instruments, etc. These devices achieve treatment effects such as tissue cutting, hemostasis, or healing by outputting energy to the diseased tissues of patients. When performing surgery, doctors usually need to clamp the target tissue and output energy. The traditional operation method usually requires doctors to rely on their own experience and, through the cooperation of the eyes and hands, judge whether the clamping force is appropriate to ensure that the output effect of the device can effectively achieve the expected result.
[0003] However, in the prior art, since doctors need to perform operations such as clamping and pressing buttons simultaneously, the hands may deform, resulting in the failure of the clamping action, thereby affecting the surgical effect. Specifically, doctors often manually activate the energy output of the device after judging whether the clamping is successful. During this process, due to the possible conflict between the clamping and button operation actions, it is impossible to maintain a stable clamping force, ultimately affecting the output effect of the device and the treatment result.
[0004] Therefore, how to improve the operation method in the prior art, avoid clamping failure caused by 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

[0034] Figure 1 A structural block diagram of an energy output device showing an embodiment of the present invention is as Figure 1 shown, and the energy output device 100 includes: A first sensor 101 for detecting the clamping pressure value when the user clamps; A second sensor 102 for detecting the temperature value of the user contact surface; A signal processing unit 103, connected to the first sensor 101 and the second sensor 102, for determining that the user's clamping of the target tissue is effective when the clamping pressure value detected by the first sensor 101 and the temperature value of the user contact surface of the second sensor 102 simultaneously meet the set conditions; An energy output unit 104, connected to the signal processing unit 103, for outputting energy to the target tissue when the user's clamping of the target tissue is effective.
[0035] Specifically, the energy output device provided in this application includes a first sensor 101 and a second sensor 102. Among them, the first sensor 101 is used to detect the clamping pressure value applied when the user clamps, and the second sensor 102 is used to detect the temperature value of the contact surface. When the clamping pressure value detected by the first sensor 101 reaches or exceeds a preset value (for example, greater than or equal to 15 N), and the temperature value of the contact surface detected by the second sensor 102 is greater than or equal to the human body standard temperature (36 - 37 °C) and significantly higher than the ambient temperature (for example, 20 °C), the system will automatically determine that the clamping is effective. This kind of energy output device can effectively distinguish whether the user successfully contacts the target tissue, avoiding ineffective treatment or injury caused by improper contact.
[0036] The technical solution of this application can significantly improve the automation level of the device and the precision of the operation. 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 operations. This process of automatic judgment and energy output avoids mis-triggering or mis-operation that may be caused by manual operation of doctors, effectively reduces the operation burden of doctors, and improves the success rate and safety of the operation. In addition, when the system detects that the clamping is ineffective (such as insufficient pressure value or temperature value lower than the preset standard), the energy output will be stopped, so as to ensure that treatment is only carried out under the condition of correct clamping, reducing potential treatment risks. Through this kind of intelligent operation, this application can improve the reliability, precision and safety of medical devices and has broad application prospects.
[0037] In one embodiment, the signal processing unit 103 is configured to determine that the clamping state of the user on the target tissue is an effective state when the effective value of the clamping pressure value detected by the first sensor 101 is greater than or equal to the preset pressure value and the temperature value of the user contact surface detected by the second sensor 102 is greater than or equal to the preset temperature value.
[0038] 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 the preset standard values. When the following conditions are met, the signal processing unit 103 considers the clamping state to be effective: The effective value of the clamping pressure detected by the first sensor 101 must be greater than or equal to a preset pressure value. The setting of this pressure value is based on the physical characteristics of the target tissue and treatment requirements. Generally, the setting of this preset pressure value will be adjusted according to different surgical scenarios and treatment needs. For example, for soft tissues, the pressure value may be set to 15N - 30N. By setting this pressure condition, the system can ensure that the user's clamping force is large enough to effectively fix the target tissue and provide a stable basis for energy output. The contact surface temperature value detected by the second sensor 102 must be greater than or equal to a preset temperature value. Since the target tissue usually matches the internal body temperature of the human body, the change in the contact surface temperature can reflect whether there is effective contact with the living tissue. In a common embodiment, the normal body temperature range of the human body is 36°C to 37°C, and the ambient temperature is generally about 20°C. When the detected temperature value of the second sensor 102 is greater than or equal to the preset standard temperature value (such as 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 whether there is poor contact and avoid false judgments caused by low temperature signals. By simultaneously meeting these two conditions, the signal processing unit 103 determines that the clamping state of the user on the target tissue is an effective state. When the clamping state is confirmed to be effective, the signal processing unit 103 will send a signal to the energy output unit 104 to trigger the output of energy and start the treatment operation. This process not only ensures the accuracy of the treatment but also automatically avoids the treatment risks brought by improper clamping or incomplete contact.
[0039] This embodiment greatly improves the intelligence level and safety of the energy output device by integrating multiple detection mechanisms for pressure and temperature. This intelligent judgment process reduces the operator's dependence on judgment, reduces the risk of human error, and ensures that energy output can only be performed when the clamping and contact conditions meet the standards, further improving the success rate and safety of surgical treatment.
[0040] In one embodiment, the signal processing unit 103 is configured to determine that the clamping state of the user on the target tissue is an invalid state when the effective value of the clamping pressure detected by the first sensor 101 is less than the preset pressure value or the temperature value of the user contact surface detected by the second sensor 102 is less than the preset temperature value.
[0041] Specifically, when the signals detected by the first sensor 101 and the second sensor 102 do not meet the preset criteria, the signal processing unit 103 determines that the clamping state of the user on the target tissue is an invalid state and takes corresponding measures to prevent energy output. When the effective value of the clamping pressure value detected by the first sensor 101 is less than the preset pressure value, the signal processing unit 103 determines that the clamping state is invalid. The preset pressure value is set according to the physical characteristics of the target tissue, surgical requirements, and treatment purposes. If the pressure value is insufficient, it indicates that the clamping force is not enough to effectively fix the target tissue, resulting in difficult guarantee of the treatment effect. For example, if the pressure value is less than 15 N, it indicates that the clamping is unstable, easily leading to inaccurate treatment or tissue damage. At this time, to avoid incorrect operations or surgical risks, the signal processing unit 103 determines that the clamping is invalid and stops the energy output. When the temperature value of the user contact surface detected by the second sensor 102 is less than the preset temperature value, the signal processing unit 103 also determines that the clamping state is invalid. Under normal circumstances, the human contact temperature range should be between 36°C and 37°C, while the ambient temperature is usually around 20°C. When the second sensor 102 detects that the contact surface temperature is lower than the preset standard temperature (e.g., lower than 36°C), it indicates that the contact is incomplete or not in successful contact with the target tissue. At this time, the low-temperature signal indicates that the sensor may be in the wrong contact position or have poor contact with the target tissue. To avoid incorrect energy output leading to treatment failure or injury, the signal processing unit 103 determines that the clamping is invalid and ensures that energy output is only carried out under effective contact conditions.
[0042] Figure 2 The structural block diagram of an energy output device showing another embodiment of the present invention is as Figure 2 shown. The energy output device 200 includes: a handle unit 105, on which the first sensor 101 and the second sensor 102 are provided; a signal source unit 106, including a square wave generating part 109, a signal shaping part 110, a first isolation transformer 107, and a second isolation transformer 108. The square wave generating part and the signal shaping part are used to convert a square wave signal into a sine wave signal and provide it to the handle unit 105. The first sensor 101 is connected to the first isolation transformer 107, The second sensor 102 is connected to the second isolation transformer 108, 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.
[0043] Specifically, the handle unit 105 is the operating device of the equipment, and the user performs the clamping operation of the target tissue through this unit. The first sensor 101 and the second sensor 102 are respectively arranged on the handle unit 105, and they work together to sense the effectiveness of the clamping.
[0044] The main function of the signal source unit is to generate and shape signals suitable for transmission by the handle unit 105. Square wave generating section: This section generates a square wave signal by the PWM (pulse width modulation) module of the single-chip microcomputer, usually a square wave of a certain frequency (such as 10 kHz), which serves as the basic signal source of the system. This signal will be converted into a sine wave signal in the subsequent processing process to meet the working requirements of the sensor. The function of the signal shaping section is to convert the square wave signal into a sine wave signal. Although the square wave signal is easy to generate, it contains more high-frequency noise, while the sine wave signal is smoother and suitable for data processing by the sensor. By using components such as capacitors and resistors, the signal shaping section can effectively remove the noise and shape the signal into a stable sine wave, which is transmitted to the handle unit 105 for measurement and processing. The first isolation transformer 107 and the second isolation transformer 108 provide the functions of 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 very important because it can prevent damage or malfunction caused by electrical faults or high voltages. The transformer transmits the signal through electromagnetic induction, avoiding the electrical interference problems that may be brought by direct connection. The first isolation transformer 107 and the second isolation transformer 108 are respectively responsible for transmitting the signals from the pressure sensor and the temperature sensor to the signal source unit, while maintaining electrical isolation to ensure the safe and stable operation of the system.
[0045] 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 transmit signals through electromagnetic induction, thus avoiding problems caused by direct electrical connection, such as current reversal or voltage fluctuation. Specifically, when the sensors in the handle unit 105 obtain pressure signals or temperature signals, these signals will be transmitted through the corresponding isolation transformers to ensure that the signal quality is not affected by electrical interference during transmission. Another important function of the first isolation transformer 107 and the second isolation transformer 108 is to provide protection when a fault occurs in the system. When a short circuit or fault occurs in the sensors or related circuits 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, thus avoiding equipment damage. Through this design, this application ensures that the equipment can still work stably and reliably in a complex surgical environment, reducing potential safety hazards caused by electrical faults.
[0046] In one embodiment, at least two electrodes are provided inside the first sensor. When the user grips 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 the original no-load state to a short-circuit state; the equivalent impedance of the primary of the first isolation transformer 107 also becomes extremely small, and the effective value of the current signal at the first detection point becomes smaller. When the single-chip microcomputer collects the signal at the first detection point and calculates that the effective value of the current is less than the first set current, it is determined that the effective value of the clamping pressure is greater than or equal to the preset pressure value.
[0047] In one embodiment, when the user relaxes the grip on the handle unit 105, the first sensor 101 returns to its 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 also becomes extremely large, 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 at the first detection point is greater than or equal to the first set current, and it is determined that the effective value of the clamping pressure is less than the preset pressure value.
[0048] By adopting the design of a pressure sensor with at least two electrodes, this application 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 operations and reduces the potential risks caused by insufficient clamping, excessive or too small clamping force. Through the electrode short-circuit triggering mechanism and the electrical isolation design of the isolation transformer, the data stability and security during signal transmission can be ensured. In addition, when the user relaxes the grip on the handle unit 105, the first sensor 101 returns to its normal state, the secondary impedance of the first isolation transformer 107 returns to no-load, the effective value of the signal at the first detection point increases, the single-chip microcomputer collects the signal again and judges whether the clamping pressure value is less than the preset pressure value, so as to automatically stop the energy output. This can ensure that the device only performs treatment when the clamping is effective, further ensuring the safety of the patient.
[0049] In one embodiment, when the user grips the handle unit 105, the impedance ratio of the second sensor 102 is larger than that at room temperature, the secondary impedance of the second isolation transformer 108 becomes larger, the equivalent impedance of the primary of the second isolation transformer 108 also becomes larger, and the effective value of the signal detected at the second signal point will increase. When the single-chip microcomputer collects the signal at the second signal point and calculates that the corresponding signal current value is 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.
[0050] In one embodiment, when the user relaxes the clamping handle unit 105, the temperature around the second sensor 102 is at 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 becomes smaller, and the equivalent impedance of the primary also becomes smaller. The effective value of the signal detected at the second signal point will decrease; When the microcontroller 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.
[0051] By introducing the second sensor 102 and its cooperation with the second isolation transformer 108, it is possible to automatically monitor the effectiveness of clamping during the operation and judge the accuracy of the contact state according to the temperature change. Specifically, the system determines whether there is effective contact with the target tissue by detecting the temperature change in real time. When the clamping is effective, the energy output is triggered, which not only improves the accuracy of the energy output but also reduces the risk of misoperation and treatment failure.
[0052] In one embodiment, the energy output unit 104 is configured to output different intensities of energy to the target tissue according to the user clamping pressure value detected by the first sensor 101 and the user temperature value and ambient temperature value detected by the second sensor 102.
[0053] In one embodiment, the signal processing unit 103 is further configured to set different clamping pressure values detected by the first sensor 101 and the temperature value of the target tissue of the second sensor 102 according to different users to adapt to different users.
[0054] Specifically, through an intelligent signal processing mechanism, it is possible to dynamically adjust the intensity of the energy output 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 an appropriate intensity of energy. This adjustment process is based on real-time data and can flexibly respond to changes in the clamping force and temperature. For example, when the clamping pressure is high, the system can output a higher intensity of energy for treatment; while when the clamping pressure is low, the system will automatically reduce the energy output to ensure the accuracy and safety during the treatment process. Through this intelligent adjustment, the energy output unit 104 not only improves the automation level of the device but also effectively avoids misoperations caused by improper clamping, ensuring the efficiency of the treatment and the safety of the patient.
[0055] In one embodiment, the first sensor 101 includes, but is not limited to, a thin-film pressure sensor that detects the clamping pressure signal when the user clamps; the clamping pressure value is determined according to the pressure signal. Specifically, the first sensor 101 includes, but is not limited to, a thin-film pressure sensor that is used to detect the clamping pressure signal applied by the user during clamping in real time. The thin-film pressure sensor senses the pressure change applied to the target tissue and converts it into an electrical signal, which is provided to the signal processing unit 103. The signal processing unit 103 determines the clamping pressure value according to the received pressure signal. This pressure value is used to judge whether the clamping force of the user meets the preset standard, ensure stable clamping and effective fixation of the target tissue, and provide accurate basic data for subsequent treatment operations.
[0056] In one embodiment, according to the second sensor 102 includes, but is not limited to, a thin-film temperature sensor that detects the impedance value of the target tissue when the user clamps, and determines the temperature value of the target tissue according to the impedance value. Specifically, the second sensor 102 includes, but is not limited to, a thin-film temperature sensor that is used to detect the contact surface temperature of the target tissue when the user clamps. 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 higher while the ambient temperature is lower, the impedance of the sensor changes with temperature. The signal processing unit 103 calculates and determines the temperature value of the target tissue according to the impedance value measured by the sensor. The change in the temperature value can reflect whether the contact is sufficient, help judge whether an effective contact has been established with the target tissue, and thus provide an important basis for the effectiveness of energy output.
[0057] In an embodiment of the present invention, the calculation method of the thin-film pressure sensor involves real-time monitoring of the change in the resistance characteristics of the sensor when pressure is applied to the gripper. Usually, before the operation, the clamping force of the gripper on the blood vessel should be controlled between 15 - 30 N to ensure the stability of clamping and the accuracy of treatment. To accurately detect the clamping state, the thin-film pressure sensor in the gripper senses the applied clamping pressure and changes its resistance characteristics according to the pressure change. Specifically, when the pressure increases, the resistance value of the thin-film pressure sensor decreases. This change rule is achieved through the change in the resistance characteristics of the sensor material. When the clamping force reaches 15 N, the resistance value of the thin-film pressure sensor will decrease significantly, dropping below 10 ohms. This change is due to the response of the sensor material to pressure. When the sensor resistance decreases to 10 ohms, the resistance of the secondary winding of the transformer is about 100 ohms, and at this time, the effective value of the alternating current in the secondary winding is about 10 mA. Since the turns ratio of the primary and secondary windings of the transformer is 2:1, the change in the secondary winding current will cause a change in the primary winding current, so the primary winding current will become 5 mA. According to the internal resistance of the primary winding circuit (about 200 ohms), the effective value of the voltage at the primary winding acquisition point will increase accordingly, reaching 1 V. In this way, the system can judge the clamping state based on the change in the voltage signal. When the effective value of the primary winding voltage reaches or exceeds 1 V, the single-chip microcomputer collects this signal and analyzes it. At this time, the threshold is set to 1 V, and through this voltage value, it can be determined that the gripper has clamped the blood vessel to an effective state. After this determination is triggered, the system will enter the energy output mode and start corresponding treatment operations. This method realizes the accurate detection of the clamping state and provides a direct feedback mechanism through the change in the voltage signal, ensuring that the device will only perform energy output when the clamping intensity meets the preset standard. This way avoids treatment failures caused by insufficient or unstable clamping and improves the accuracy and safety of the treatment process.
[0058] This application can determine whether the doctor's clamping of the target tissue is successful by detecting the changes in the thin-film temperature and the thin-film pressure sensor on the handle. When the standard is reached, the energy output device will automatically perform excitation output, ensuring a high success rate for this operation and achieving the best effect. This method can greatly simplify the operation steps of the surgeon, effectively reduce the fatigue of the doctor's hand, and increase the success rate of the operation. Figure 3 A schematic circuit diagram of an energy output device showing another embodiment of the present invention is as Figure 3 shown. The energy output device 200 includes a front-end handle unit, a signal source unit, a signal monitoring and energy output unit.
[0059] Specifically, the function of the front-end handle unit is that the doctor can use this part to clamp the surgical site and apply the output energy thereto. This 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 deformation inside it. 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, utilizing the temperature characteristics of platinum metal (its impedance value is different at different temperatures). When a living tissue contacts this sensor, since the temperature of the living tissue is higher than the ambient temperature of the operating room, the impedance value of this sensor will change significantly.
[0060] 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 emits a 10 kHz square-wave signal through the internal PWM function module at the IO pin, and then through the signal shaping part, converts the square-wave signal into a sine-wave signal and emits it to the handle unit through the secondary side of the isolation transformer. The isolation transformer has two functions: First, once a fault occurs in the handle unit, resulting in a short circuit of the sensor, due to the existence of the isolation transformer, it will not cause damage to the signal source unit; Second, when energy is output, high voltage often accompanies it, and this isolation transformer can effectively isolate the high-frequency high-voltage signal to ensure that the circuit of the signal source unit will not be broken down and damaged.
[0061] The signal monitoring and energy output unit includes a signal acquisition function part, usually a single-chip microcomputer, a calculation and judgment function part, usually a single-chip microcomputer, and an energy output part. The single-chip microcomputer uses the internal ADC to collect two detection signals. After reaching a cycle time (100 us), all the data are calculated by the root mean square to obtain the effective value of the voltage signal. When the collected effective value continuously remains within the threshold for a certain period of time, it can be determined that the clamping state of the target tissue is good and the condition for energy output is met. At this time, this determination is sent to the energy output part to perform the corresponding energy output operation.
[0062] Method for determining effectiveness: There are two determination conditions, and both must be met simultaneously to be determined as effective clamping. First, when the two electrodes inside the thin-film pressure sensor are short-circuited due to the extrusion of the clamped tissue, the secondary impedance of the isolation transformer T1 changes from the original no-load (extremely large) to a short circuit (extremely small). At this time, the equivalent impedance of the primary of the isolation transformer will also become extremely small, and the effective value of the signal at the detection signal 1 is very small. At this time, the effective value of the signal collected and calculated by the single-chip microcomputer must be less than the threshold, so it can be determined that this path of the signal shows an effective state. When the doctor relaxes the clamping end and the thin-film pressure sensor returns to the normal state, the secondary impedance of the isolation transformer T1 returns to no-load (extremely large), and the equivalent impedance of the primary will also become extremely large. The effective value of the signal at the detection signal returns to the maximum value, and the effective value of the signal collected and calculated by the single-chip microcomputer must be greater than the threshold. At this time, it can be determined that this path of the signal shows an ineffective state. Second, when the thin-film temperature sensor has a higher impedance ratio than at room temperature because the temperature of the clamped living tissue is higher than the ambient temperature, the secondary impedance of the isolation transformer T2 increases. At this time, the equivalent impedance of the primary of the isolation transformer will also increase, and the effective value of the signal at the detection signal 2 will increase. At this time, the effective value of the signal collected and calculated by the single-chip microcomputer will increase, and when it reaches the threshold, it can be determined that this path of the signal shows an effective state. When the doctor relaxes the clamping end and the temperature around the thin-film temperature sensor is at room temperature, the impedance ratio of the sensor is smaller than when there is tissue, the secondary impedance of the isolation transformer T2 decreases, and the equivalent impedance of the primary will also decrease. The effective value of the signal at the detection signal 2 will decrease. When the effective value of the signal collected and calculated by the single-chip microcomputer is less than the threshold, it can be determined that this path of the signal shows an ineffective state. When both paths of judgment signals are in an effective state, the judgment result is effective; when any one path of the signal is in an ineffective state, the judgment result is ineffective. When the judgment result is effective, the energy device performs corresponding output.
[0063] Compared with the prior art, the beneficial effects of this application include: 1. In the prior art, basically physical buttons installed on the handle are used to control the output, which may cause mis-triggering or energy output without meeting the triggering requirements. In this application, energy output will only occur when the excitation conditions are truly met. This output does not require manual judgment, which greatly reduces failures or poor effects caused by operator errors.
[0064] 2. The device automatically judges the output conditions, which can reduce the doctor's hand fatigue and the workload of the operator.
[0065] 3. The detection unit has an isolation transformer, which can isolate external energy signals and effectively protect the device.
[0066] 4. When the handle malfunctions, the detection unit can immediately detect the problem and stop the energy output, which can better protect the safety of patients more quickly compared to controlling by physical buttons.
[0067] This application also provides an energy output method, including: Step 401, the first sensor detects the clamping pressure value when the user clamps; Step 402, the second sensor detects the contact surface temperature value when the user clamps; 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; Step 404, if the user's clamping of the target tissue is effective, output energy to the target tissue.
[0068] In one embodiment, when the effective value of the clamping pressure value detected by the first sensor is greater than or equal to the preset pressure value and the temperature value of the user contact surface detected by the second sensor is greater than or equal to the preset temperature value, it is determined that the clamping state of the user to the target tissue is an effective state; In one embodiment, when the effective value of the clamping pressure value detected by the first sensor is less than the preset pressure value or the temperature value of the user contact surface detected by the second sensor is less than the preset temperature value, it is determined that the clamping state of the user to the target tissue is an ineffective state.
[0069] In one embodiment, the clamping pressure when the user clamps is detected by at least two electrodes of the first sensor arranged. When the clamping pressure reaches the preset pressure, the two electrodes are short-circuited; after detecting that the two electrodes are short-circuited, it is determined that the secondary impedance of the isolation transformer changes from the original no-load to a short circuit, and correspondingly the primary equivalent impedance becomes extremely small; the current signal at the first detection signal point is collected and the effective current value is calculated. When the effective current value is less than the preset current, it is determined that the clamping pressure value is greater than or equal to the preset pressure value.
[0070] In one embodiment, when the user relaxes the clamping, the two electrodes return to the normal state, the secondary impedance of the isolation transformer returns to no-load, and the primary equivalent impedance returns to extremely large; the signal value at the first signal point is collected and the effective current value is calculated. When the effective current value is greater than or equal to the preset current, it is determined that the clamping pressure value is less than the preset pressure value.
[0071] In one embodiment, when the user grips the handle unit, the impedance ratio of the second sensor is greater than that at room temperature. The impedance of the secondary of the second isolation transformer increases, and the equivalent impedance of the primary of the second isolation transformer also increases. The effective value of the signal detected at the second signal point will increase. When the single-chip microcomputer collects the signal at the second signal point and calculates that the corresponding signal current value is 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.
[0072] In one embodiment, when the user relaxes the grip on the handle unit, the temperature around the second sensor is at room temperature. The impedance ratio of the thin-film sensor is smaller than when there is tissue. The impedance of the secondary of the second isolation transformer decreases, and the equivalent impedance of the primary also decreases. 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.
