Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and in particular to an electrocoagulation forceps and a control method for the electrocoagulation forceps. Background Art

[0002] Hemostasis is a basic and special problem in neurosurgery. The application of bipolar electrocoagulation makes neurosurgery hemostasis more convenient and quick, and no foreign matter is left in the tissue. Postoperative CT (Computed Tomography) review is not disturbed by artifacts. Compared with monopolar electrocoagulation hemostasis, bipolar electrocoagulation hemostasis is more accurate and causes less damage to surrounding tissues. Even if electrocoagulation hemostasis is performed on the surface of the brainstem, it rarely affects the normal activities of breathing and heart. It has become an important part of current microneurosurgical operation technology and one of the most commonly used neurosurgical equipment.

[0003] In addition, in neck surgeries (such as thyroid malignant tumor surgery), electrocoagulation forceps are also needed to electrocoagulate small blood vessels to stop bleeding. Small blood vessels are similar to nerves in the naked eye. If the resection range is close to important structures such as the superior laryngeal nerve and accessory nerve, the nerves are mistaken for blood vessels and electrocoagulated, which will cause nerve damage, which is one of the main complications of surgery.

[0004] In order to avoid damage to nerves during surgery, current electrocoagulation forceps usually have a nerve detection function, which can detect whether there are nerves in the operation area before electrocoagulation, and perform surgical operations (such as electrocoagulation operations) normally if no nerves are detected.

[0005] However, although the current electrocoagulation forceps have a nerve detection function, they switch functions through a manual switch, that is, they need to manually switch between the nerve monitoring function and the high-frequency electrocoagulation function during use, which makes it inconvenient to use during actual surgery. In addition, since high-frequency electrocoagulation will significantly increase the temperature of the forceps tip, in the process of switching from the high-frequency electrocoagulation function to the nerve monitoring function, the forceps tip is overheated and easily damages the nerve tissue.

They are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the referred elements must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limitations on the present disclosure. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0052] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0053] Among them, electrical connection can be understood as the process of connecting different components in electronic equipment through electrical connection. The main function of electrical connection is to transmit electrical signals and electrical energy to achieve control and regulation of various electronic equipment. Mechanical connection refers to the way of connecting two or more components together by physical means.

[0054] A high-frequency surgical instrument is an electrosurgical device that replaces mechanical scalpels for tissue cutting. It heats the tissue when the high-frequency and high-voltage current generated by the effective electrode tip comes into contact with the body, thereby separating and coagulating the body tissue, thereby achieving the purpose of cutting and hemostasis.

[0055] Electrocoagulation forceps are a type of high-frequency surgical instrument. In neck surgery, especially thyroid malignant tumor surgery, electrocoagulation forceps are needed to electrocoagulate small blood vessels to stop bleeding. In order to avoid nerve damage during surgery, some electrocoagulation forceps usually have a nerve detection function, which can detect whether there are nerves in the operation area before electrocoagulation, and perform necessary surgical operations normally if no nerves are detected.

[0056] However, research has found that although the current electrocoagulation forceps have a nerve detection function, they use a manual switch to switch between functions, that is, they need to manually switch between the nerve monitoring function and the high-frequency electrocoagulation function during use, which makes it inconvenient to use during actual surgery. In addition, in the process of switching from the high-frequency electrocoagulation function to the nerve monitoring function, the nerve tissue is easily damaged due to overheating of the forceps tip.

[0057] Based on the above research, the embodiment of the present disclosure provides an electrocoagulation forceps, which includes a forceps base, a pair of forceps tips, an electrocoagulation cutting connection end, a nerve monitoring connection end, and a function switching circuit, wherein the function switching circuit is electrically connected to the electrocoagulation cutting connection end, the nerve monitoring connection end, and the pair of forceps tips, respectively; the electrocoagulation cutting connection end is used to connect to a high-frequency generator device, and the nerve monitoring connection end is used to connect to a nerve monitor. The function switching circuit includes a high-frequency excitation identification circuit, a controller, and a nerve monitoring switching circuit.

[0058] Among them, the high-frequency excitation identification circuit is used to detect whether the high-frequency generator device outputs a high-frequency excitation signal, and generates a corresponding induction signal according to whether the high-frequency excitation signal is detected. The input end of the controller is connected to the output end of the high-frequency excitation identification circuit, and is used to determine whether the electrocoagulation and cutting function of the electrocoagulation forceps is turned on according to the induction signal, and after determining that the electrocoagulation and cutting function of the electrocoagulation forceps is converted from the on state to the off state, start timing and determine the target delay time, and generate a first control signal; after the timing time reaches the target delay time, the controller generates a first prompt signal; the first prompt signal is used to instruct the prompt device to generate a first prompt information, and the first prompt information is used to prompt the user that the electrocoagulation forceps can perform nerve monitoring. The nerve monitoring switching circuit is connected to the control end of the controller, and is used to connect the nerve monitoring connection end with the pair of forceps tips in response to the first control signal, so that the nerve stimulation signal of the nerve monitor is output through the pair of forceps tips.

[0059] The electrocoagulation forceps with intraoperative nerve detection function provided by the embodiment of the present disclosure can detect whether the high-frequency generator device outputs a high-frequency excitation signal through a high-frequency excitation identification circuit, and generate a corresponding induction signal according to whether the high-frequency excitation signal is detected. The controller can determine whether the electrocoagulation and cutting function of the electrocoagulation forceps is turned on according to the induction signal, and when it is determined that the electrocoagulation and cutting function of the electrocoagulation forceps is converted from an on state to an off state, the electrocoagulation forceps is controlled to output the nerve stimulation signal of the nerve monitor. In this way, automatic switching between the electrocoagulation and cutting function and the nerve detection function can be achieved without the need for manual switching by the user, thereby improving the convenience of operation. In addition, when the target delay time is reached after the electrocoagulation and cutting function is turned off, the first prompt information is generated to let the user know that the electrocoagulation forceps can perform nerve monitoring, thereby avoiding the situation where the nerve tissue is damaged due to overheating of the forceps tip, thereby reducing the probability of nerve tissue damage during the switching process.

[0060] The electrocoagulation forceps and the control method of the electrocoagulation forceps provided in the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0061] See also Figure 1 As shown in FIG. 1 , a three-dimensional structural schematic diagram of an electrocoagulation forceps provided in an embodiment of the present disclosure is shown. Figure 1 As shown, the electrocoagulation forceps 100 comprises a pair of forceps tips 101, an electrocoagulation cutting connection end 102, a nerve monitoring connection end 103 and a function switching circuit 104. The function switching circuit 104 is electrically connected to the electrocoagulation cutting connection end 102, the nerve monitoring connection end 103 and the pair of forceps tips 101 respectively.

[0062] Please refer to Figure 2 ,in, Figure 2 The functional block diagram of a function switching circuit provided in an embodiment of the present disclosure. The function switching circuit 104 includes a high-frequency excitation identification circuit 20, a controller 30, and a nerve monitoring switching circuit 40. The input end of the controller 30 is connected to the output end of the high-frequency excitation identification circuit 20, and the control end of the controller 30 is connected to the nerve monitoring switching circuit 40. The electrocoagulation and cutting connection terminal 102 is used to connect to the high-frequency generator device 200, and the nerve monitoring connection terminal 103 is used to connect to the nerve monitor 300. In addition, the nerve monitoring connection terminal 103 and the electrocoagulation and cutting connection terminal 102 are both connected to the nerve monitoring switching circuit 40.

[0063] Specifically, the nerve monitoring switching circuit 40 may include a first input terminal (corresponding to Figure 4 Pins 4 and 5), the second input terminal (corresponding to Figure 4 Pins 2 and 7) and output terminals (corresponding to Figure 4Middle pins 3 and 6), the first input end is connected to the nerve monitoring connection end 103, the second input end is connected to the electrocoagulation cutting connection end 102, and the output end is connected to the pair of forceps tips 101.

[0064] In the disclosed embodiment, the electrocoagulation forceps 100 are bipolar electrocoagulation forceps. In other embodiments, the electrocoagulation forceps 100 may also be monopolar electrocoagulation forceps.

[0065] In some embodiments, Figure 1 As shown, a pair of forceps tips 101, the electrocoagulation cutting connection terminal 102 and the nerve monitoring connection terminal 103 are respectively connected to the forceps base 10, and the function switching circuit 104 is arranged in the forceps base 10. Specifically, a pair of forceps tips 101 are arranged at one end of the forceps base 10, and the side of the forceps base 10 away from the pair of forceps tips 101 is provided with the electrocoagulation cutting connection terminal 102 and the nerve monitoring connection terminal 103. It can be understood that the electrocoagulation cutting connection terminal 102 can be connected to the forceps base 10 through a high-frequency cable, and the nerve monitoring connection terminal 103 can be connected to the forceps base 10 through a detection line.

[0066] In other embodiments, the function switching circuit 104 can also be arranged outside the forceps seat 10, that is, the function switching circuit 104 can be arranged at any position of the electrocoagulation forceps 100 according to actual needs, for example, it can be the position where the forceps tip 101 is close to the forceps seat 10, or it can be any position between the forceps seat 10 and the electrocoagulation cutting connection terminal 102, or it can be arranged on the other side of the connection side between the electrocoagulation cutting connection terminal 102 and the high-frequency generator device 200.

[0067] In an optional embodiment, the electrocoagulation forceps further include a circuit accommodating device for accommodating the function switching circuit 104. The circuit accommodating device is disposed between the forceps seat 10 and the electrocoagulation cutting connection terminal. For example, the circuit accommodating device may be a hollow container, and the function switching circuit 104 is disposed in the container. The function switching circuit 104 is electrically connected to the electrocoagulation cutting connection terminal, the nerve monitoring connection terminal, and a pair of forceps tips through a connection structure (such as a through hole or other structure capable of realizing electrical connection between the inside and outside of the circuit accommodating device) provided in the circuit accommodating device. For example, a wire electrically connected to the corresponding input terminal and output terminal of the function switching circuit passes through the above-mentioned through hole and is electrically connected to the corresponding connection terminal or forceps tip.

[0068] In some optional embodiments, the high-frequency excitation identification circuit 20, the controller 30, and the nerve monitoring switching circuit 40 can be arranged on a printed circuit board, and the circuit board can be placed in the forceps base 10, that is, the high-frequency excitation identification circuit 20, the controller 30, and the nerve monitoring switching circuit 40 can be integrated in the forceps base 10. Of course, in other embodiments, the high-frequency excitation identification circuit 20, the controller 30, and the nerve monitoring switching circuit 40 can also be respectively arranged in different parts of the electrocoagulation forceps 100, which can be determined according to actual needs.

[0069] Specifically, the high-frequency excitation identification circuit 20 is used to detect whether the high-frequency generator device 200 outputs a high-frequency excitation signal, and generates a corresponding induction signal according to whether the high-frequency excitation signal is detected. The controller 30 is used to determine whether the electrocoagulation and cutting function of the electrocoagulation forceps 100 is turned on according to the induction signal, and after determining that the electrocoagulation and cutting function of the electrocoagulation forceps 100 is converted from the on state to the off state, start timing and determine the target delay time, and generate a first control signal; after the timing time reaches the target delay time, the controller 30 generates a first prompt signal; the first prompt signal is used to instruct the prompt device to generate a first prompt information, and the first prompt information is used to prompt the user that the electrocoagulation forceps 100 can perform nerve monitoring; the nerve monitoring switching circuit 40 is used to respond to the first control signal to connect the nerve monitoring connection terminal 103 with the pair of forceps tips 101, so that the nerve stimulation signal of the nerve monitor 300 is output through the pair of forceps tips 101.

[0070] After determining that the electrocoagulation cutting function of the electrocoagulation forceps 100 is switched from the on state to the off state, starting timing and determining the target delay time, and generating a first control signal, includes:

[0071] After determining that the electrocoagulation cutting function of the electrocoagulation forceps 100 is switched from the on state to the off state, a first control signal may be generated to start timing and determine a target delay time; or,

[0072] After determining that the electrocoagulation cutting function of the electrocoagulation forceps 100 is switched from the on state to the off state, timing is started and a target delay time is determined, and a first control signal is generated after the timing time reaches the target time.

[0073] That is to say, after determining that the electrocoagulation cutting function of the electrocoagulation forceps 100 is converted from the on state to the off state, a first control signal is generated, and the timing is started and the target delay time is determined. The actions can be performed simultaneously, or the first control signal can be generated after the target delay time, without specific limitation.

[0074] It is understandable that the prompt device can be integrated into the electrocoagulation forceps 100, or can be separately provided from the electrocoagulation forceps 100. That is, when the prompt device is separately provided from the electrocoagulation forceps 100, the electrocoagulation forceps 100 can send the first control signal generated by the controller 30 to the prompt device to control the prompt device to issue a prompt message, thereby reminding the user. For example, the prompt device can be an independent speaker, which can issue a voice prompt message of "You can now perform nerve detection" after receiving the first control signal.

[0075] Optionally, the controller 30 is also used to generate a second control signal when it is determined that the electrocoagulation cutting function of the electrocoagulation forceps 100 is turned on; the nerve monitoring switching circuit 40 is also used to disconnect the nerve monitoring connection terminal 103 from the pair of forceps tips 101 in response to the second control signal to stop outputting the nerve stimulation signal of the nerve monitor 300 through the pair of forceps tips 101.

[0076] That is, when receiving the first control signal, the nerve monitoring switching circuit 40 electrically connects the first input terminal with the output terminal, so that the nerve monitoring connection terminal 103 is conductively connected to the pair of forceps tips 101; when receiving the second control signal, the nerve monitoring switching circuit electrically connects the second input terminal with the output terminal, so that the electrocoagulation and cutting connection terminal 102 is conductively connected to the pair of forceps tips 101, and the nerve monitoring connection terminal 103 is disconnected from the pair of forceps tips 101.

[0077] The high-frequency excitation signal may be a high-frequency current signal, and the nerve stimulation signal may be a current signal (stimulation current). The first control signal may be one of a high-level signal and a low-level signal, and the second control signal may be the other of a high-level signal and a low-level signal, that is, if the first control signal is a high-level signal, the second control signal may be a low-level signal.

[0078] Specifically, the specific logic by which the controller 30 determines whether the electrocoagulation and cutting function of the electrocoagulation forceps 100 is turned on according to the sensing signal is not limited. For example, the controller 30 can determine that the electrocoagulation and cutting function is turned on when the sensing signal is received, and determine that the electrocoagulation and cutting function is not turned on when the sensing signal is not received. It can also determine that the electrocoagulation and cutting function is turned on when the strength of the received sensing signal is greater than a preset threshold, and determine that the electrocoagulation and cutting function is not turned on when the strength of the received sensing signal is not greater than the preset threshold, wherein the situation where the strength of the sensing signal is not greater than the preset threshold also includes the situation where the strength of the sensing signal is 0, and the strength of the sensing signal being 0 can also be understood as no sensing signal is received.

[0079] See also Figure 3In some embodiments, the function switching circuit 104 also includes the aforementioned prompt device, that is, in this embodiment, the prompt device is integrated into the electrocoagulation forceps 100. In this embodiment, the prompt device can be a first prompt circuit 50, and the first prompt circuit is connected to the controller 30. The controller 30 is also used to generate a first prompt signal after the timing time reaches the target delay time. The first prompt circuit 50 is used to generate a first prompt information in response to the first prompt signal. The first prompt information is used to indicate that the nerve monitoring function of the electrocoagulation forceps is turned on. In the disclosed embodiment, the first prompt information is a light prompt information.

[0080] Optionally, the function switching circuit 104 may further include a second prompt circuit 60, which is connected to the controller 30. The controller 30 is also used to generate a second prompt signal when it is determined that the nerve monitoring function of the electrocoagulation forceps 100 is not turned on; the second prompt circuit 60 is used to generate a second prompt information in response to the second prompt signal, and the second prompt information is used to indicate that the nerve monitoring function of the electrocoagulation forceps is not turned on. In the embodiment of the present disclosure, the second prompt information is also a light prompt information, and the light color is different from the first prompt information.

[0081] It is understandable that the first prompt information and the second prompt information may also be other types of prompt information, such as voice prompt information, alarm prompt information, etc., which are not specifically limited. In addition, the first prompt signal and the second prompt signal may be low-level signals or high-level signals.

[0083] In other embodiments, the controller 30 may also be an application specific integrated circuit (ASIC), a programmable logic device (PLD), a digital signal processor (DSP) or a combination thereof. The above-mentioned PLD may be a complex programmable logic device (CPLD), a field programmable gate array (FPGA), a generic array logic (GAL) or any combination thereof, which is not specifically limited in the embodiments of the present disclosure.

[0084] In some embodiments, the electrocoagulation forceps 100 further includes a power supply device (not shown), which is used to supply power to the function switching circuit 104. The power supply device is disposed in the forceps holder 10, or in a circuit accommodating device. Exemplarily, the power supply device can be various types of batteries that can provide electrical energy (such as dry cells, button cells, or storage batteries, etc.).

[0085] Combine the following Figure 4 The specific implementation of each circuit in the electrocoagulation forceps 100 is introduced.

[0086] See also Figure 4 As shown, the high-frequency excitation identification circuit 20 may include a mutual inductor L, a first resistor R1 to a fourth resistor R4, and a comparator U. The mutual inductor L is connected in parallel with the first resistor R1 and then connected in series with the second resistor R2 between the in-phase input terminal of the comparator U and the ground, the inverting input terminal of the comparator U is grounded through the third resistor R3, the output terminal of the comparator U is connected to the input terminal of the controller 30, and the output terminal of the comparator U is also connected to the inverting input terminal of the comparator U through the fourth resistor R4. In this way, whether the high-frequency generator device 200 outputs a high-frequency excitation signal can be detected through the mutual inductor L, and after detecting that the high-frequency generator device 200 outputs a high-frequency excitation signal, an induction signal is generated, which is amplified by the comparator U and transmitted to the controller 30, so that the controller 30 obtains the corresponding induction signal.

[0087] Specifically, the mutual inductor L may be a mutual inductance coil. When a foot switch (not shown) of the high-frequency generator device 200 is triggered to output a high-frequency excitation signal, the mutual inductance coil may sense the change in current and generate a corresponding induction signal.

[0088] The nerve monitoring switching circuit 40 includes a relay K, a first electronic switch Q1, and a fifth resistor R5. The control end of the first electronic switch Q1 is connected to the control end of the controller 30, the first connection end of the first electronic switch Q1 is grounded through the fifth resistor R5, the second connection end of the first electronic switch Q1 is connected to the pin 1 of the relay K, the pin 2 of the relay K is connected to the power supply, the pin 2 and the pin 7 of the relay K correspond to the second input end of the nerve monitoring switching circuit 40, the pin 2 and the pin 7 are respectively connected to the electrocoagulation cutting connection end 102, and the high-frequency excitation signal output by the high-frequency generator device 200 can be received through the electrocoagulation cutting connection end 102. The pins 4 and 5 of the relay K correspond to the first input end of the nerve monitoring switching circuit 40, the pins 4 and 5 are both connected to the nerve monitoring connection end 103, and the nerve stimulation signal output by the nerve monitor 300 can be received through the nerve monitoring connection end 103. The pins 3 and 6 of the relay K correspond to the output end of the nerve monitoring switching circuit 40, and the pins 3 and 6 are respectively connected to a pair of forceps tips 101.

[0089] In this way, when the first electronic switch Q1 receives the first control signal and turns on, pin 5 and pin 6 of the relay K are turned on, pin 3 and pin 4 are turned on, and the nerve stimulation signal provided by the nerve monitor 300 is transmitted to the tweezer tip 101 through the nerve monitoring switching circuit 40, thereby realizing the nerve monitoring function of the electrocoagulation tweezers 100; when the first electronic switch Q1 receives the second control signal, pin 5 and pin 6 are disconnected and connected to pin 7, pin 3 and pin 4 are disconnected and connected to pin 2. At this time, the nerve stimulation signal provided by the nerve monitor 300 cannot be transmitted to the tweezer tip 101 through the nerve monitoring switching circuit 40, and the high-frequency excitation signal output by the high-frequency generator 200 can be transmitted to the tweezer tip 101 through the nerve monitoring switching circuit 40, thereby turning off the nerve monitoring function of the electrocoagulation tweezers 100 and turning on the electrocoagulation cutting function.

[0090] In the disclosed embodiment, the first electronic switch Q1 is an N-type field effect transistor, the first connection end of the first electronic switch Q1 corresponds to the source of the N-type field effect transistor, and the second connection end of the first electronic switch Q1 corresponds to the drain of the N-type field effect transistor. In other embodiments, the first electronic switch Q1 can also be a triode, etc., which is not specifically limited.

[0091] The first prompt circuit 50 includes a first light emitting diode D1, a second electronic switch Q2, and a sixth resistor R6 to an eighth resistor R8. The control end of the second electronic switch Q2 is connected to a control end of the controller 30 through the sixth resistor R6, the first connection end of the second electronic switch Q2 is grounded through the seventh resistor R7, the second connection end of the second electronic switch Q2 is connected to the cathode of the first light emitting diode D1, and the anode of the first light emitting diode D1 is connected to the power supply. In addition, the control end of the second electronic switch Q2 is also connected to the first connection end of the second electronic switch Q2 through the eighth resistor R8.

[0092] The second prompt circuit 60 is similar to the first prompt circuit 50, and includes a second light emitting diode D2, a third electronic switch Q3, and a ninth resistor R9 to an eleventh resistor R11. The control end of the third electronic switch Q3 is connected to a control end of the controller 30 through the ninth resistor R9, the first connection end of the third electronic switch Q3 is grounded through the tenth resistor R10, the second connection end of the third electronic switch Q3 is connected to the cathode of the second light emitting diode D1, and the anode of the second light emitting diode D2 is connected to the power supply. In addition, the control end of the third electronic switch Q3 is also connected to the first connection end of the third electronic switch Q3 through the eleventh resistor R11.

[0093] The first light emitting diode D1 and the second light emitting diode D2 emit different colors. In the disclosed embodiment, the first light emitting diode D1 is a green light diode, and the second light emitting diode D2 is a red light diode. In other embodiments, the first light emitting diode D1 and the second light emitting diode D2 may also be light emitting diodes of other colors, as long as the colors of the two light emitting diodes are different.

[0094] Exemplarily, the second electronic switch Q2 and the third electronic switch Q3 are both N-type field effect transistors. The first connection end of the second electronic switch Q2 and the first connection end of the third electronic switch Q3 both correspond to the source of the N-type field effect transistor, and the second connection end of the second electronic switch Q2 and the second connection end of the third electronic switch Q3 both correspond to the drain of the N-type field effect transistor.

[0095] It is understandable that in some embodiments, the first light emitting diode D1 and the second light emitting diode D2 may also be replaced by a generating device, such as a buzzer, so that prompts can be given through sound.

[0096] See also Figure 5 FIG. 1 is a circuit diagram of an electrocoagulation forceps provided by another embodiment of the present disclosure, and FIG. Figure 4The difference is that the high-frequency excitation identification circuit 20 further includes a converter X, wherein the converter X can convert the root mean square (RMS) value of the AC signal into a DC voltage, and therefore, the converter is also called an RMS-TO-DC converter.

[0097] Exemplarily, high-frequency electric energy outputs an AC signal through a transformer L, and the RMS-TO-DC converter can convert the root mean square value of the AC signal into a DC voltage. The DC voltage is compared with a set threshold value through a comparator U. When the DC voltage is higher than the threshold, 1 is output, otherwise 0 is output. After receiving the 1 signal, the relay K connects pin 6 with pin 5, and pin 3 with pin 4, so that the nerve stimulation signal of the nerve monitor 300 can be output to the tweezers tip 101 to realize the nerve monitoring function. Otherwise, pin 6 is connected to pin 7, and pin 3 is connected to pin 2, so that the high-frequency excitation signal of the high-frequency generator 200 can be output to the tweezers tip 101 to realize the electrocoagulation cutting function.

[0098] It should be noted that due to Figure 5 The circuit elements included in the high-frequency excitation identification circuit 20 are different, which leads to differences in the sensing signals output by the high-frequency excitation identification circuit 20. Therefore, the controller 30 can configure the corresponding sensing signal recognition and determination algorithm according to the circuit composition of the high-frequency excitation identification circuit 20.

[0099] In addition, the input pin VIN of the converter X is respectively connected to the first resistor R1 and the mutual inductor L through the first capacitor C1; the output pin OUTPUT of the converter X is connected to the non-inverting input terminal of the comparator U through the third resistor R3, and the output pin OUTPUT of the converter X is also connected to the pin CF of the converter X through the second capacitor C2; the power pin VS of the converter X is grounded through the third capacitor C3, and the power pin +VS is grounded through the fourth capacitor C4; the pin CAV of the converter X is connected to the power pin VS through the fifth capacitor C5; the pin COM of the converter X is connected to the pin CC of the converter X through the sixth capacitor C6.

[0100] The control method of the electrocoagulation forceps provided in the embodiment of the present disclosure is described below.

[0101] The electrocoagulation forceps may be the electrocoagulation forceps described in any of the above embodiments. Figure 6 As shown, the control method of the electrocoagulation forceps includes the following S101-S103:

[0102] S101, detecting whether the high-frequency generator device outputs a high-frequency excitation signal through a high-frequency excitation identification circuit, and generating a corresponding induction signal according to whether the high-frequency excitation signal is detected.

[0103] S102, the controller determines whether the electrocoagulation and cutting function of the electrocoagulation forceps is turned on according to the sensing signal, and when it is determined that the electrocoagulation and cutting function of the electrocoagulation forceps is switched from an on state to an off state, starts timing and determines a target delay time, and generates a first control signal to control the nerve monitoring switching circuit to output the nerve stimulation signal of the nerve monitor through the pair of forceps tips.

[0104] S103, after the timing time reaches the target delay time, the controller generates a first prompt signal; the first prompt signal is used to instruct the prompt device to generate a first prompt information, and the first prompt information is used to prompt the user that the electrocoagulation forceps can perform nerve monitoring.

[0105] In this embodiment, when it is determined that the electrocoagulation cutting function of the electrocoagulation forceps is switched from an on state to an off state, a first control signal is generated first, and then a first prompt signal is generated after the timing time reaches the target delay time.

[0106] It can be understood that in other embodiments, step S102 can also be: the controller determines whether the electrocoagulation and cutting function of the electrocoagulation forceps is turned on according to the sensing signal, and starts timing and determines the target delay time when it is determined that the electrocoagulation and cutting function of the electrocoagulation forceps is switched from the on state to the off state; accordingly, step S103 can be: after the timing time reaches the target delay time, the controller generates a first control signal and a first prompt signal; the nerve monitoring switching circuit connects the nerve monitoring connection end with the pair of forceps tips in response to the first control signal, so that the nerve stimulation signal of the nerve monitor is output through the pair of forceps tips; the first prompt signal is used to instruct the prompt device to generate a first prompt information, and the first prompt information is used to prompt the user that the electrocoagulation forceps can perform nerve monitoring. That is, in this embodiment, the first control signal and the first prompt signal are both generated after the timing time reaches the target time.

[0107] In some embodiments, the method further includes: when the controller determines that the electrocoagulation and cutting function of the electrocoagulation forceps is turned on, generating a second control signal to control the nerve monitoring switching circuit to stop outputting the nerve stimulation signal of the nerve monitor.

[0108] Specifically, when determining the target delay time, the following may be included:

[0109] Determine the preset delay time as the target delay time; or,

[0110] The operation time of the electrocoagulation forceps in the open state before closing is obtained, and the target delay time is determined according to the operation time.

[0111] That is, in some embodiments, the preset time can be directly determined as the target delay time, for example, the preset time of 4 seconds can be determined as the target delay time, so that the efficiency of determining the target delay time can be improved. Of course, the preset time can be more or less, which is not specifically limited here.

[0112] Further, the measured values ​​of the operation time of the electrocoagulation forceps and the tip temperature of the electrocoagulation forceps obtained based on the experiment are shown in Table 1. It can be seen that when the operation time is longer than a certain time, the temperature rise range of the tip temperature is small.

[0113] Table 1

[0114]

[0115] Table 2 below shows the tip temperature of the electrocoagulation forceps after the tip temperature rises to a smaller temperature rise range and the electrocoagulation cutting function of the electrocoagulation forceps is turned off.

[0116] Table 2

[0117]

[0118] It can be seen from the above table that the temperature of the electrocoagulation forceps in the electrocoagulation cutting state is related to the operation time, and after the operation time reaches the preset time, the temperature rise variation range is small. Therefore, in order to improve the accuracy of determining the target delay time, when determining the preset delay time as the target delay time, the operation time of the electrocoagulation forceps in the open state before closing can be obtained first. When the operation time is not less than the first preset time, the preset delay time is determined as the target delay time. Exemplarily, the first preset time is 5 seconds, 6 seconds, 7 seconds, etc. For example, when it is determined that the operation time of the electrocoagulation forceps is not less than 6 seconds, the preset time can be determined as the target delay time, and the preset time can be obtained through multiple experimental data.

[0119] In other embodiments, when determining the target delay time, the operation time of the electrocoagulation forceps in the open state before closing can be directly obtained, and the target delay time can be determined based on the operation time, so that the accuracy of determining the target delay time can be improved. For example, when the operation time is greater than the second preset time and less than the first preset time, the target delay time can be positively correlated with the operation time; wherein the second preset time is less than the first preset time. Exemplarily, the first preset time can be 2 seconds, and the second preset time can be 5 seconds, that is, if the operation time is between 2 seconds and 5 seconds, the target delay time can be increased as the operation time increases.

[0120] In some possible embodiments, the prompt device is a first prompt circuit. Therefore, after the timing time reaches the target delay time, the controller generates a first prompt signal to instruct the first prompt circuit to generate a first prompt information, and the first prompt information is used to prompt that the nerve monitoring function of the electrocoagulation forceps is turned on.

[0121] In some other possible embodiments, the method further includes: when the timing time does not reach the target delay time, the controller generates a second prompt signal to instruct the second prompt circuit to generate a second prompt information, and the second prompt information is used to prompt that the nerve monitoring function of the electrocoagulation forceps is not turned on.

[0122] In some optional embodiments, the control method of the electrocoagulation forceps includes the following (I) to (II):

[0123] (I) In response to the electrocoagulation cutting function of the electrocoagulation forceps being turned off, starting timing and determining a target delay time.

[0124] (II) After the timing time reaches the target delay time, the nerve detection function of the electrocoagulation forceps is controlled to start.

[0125] The process of determining the target delay time in this method can refer to the description of the aforementioned method, which will not be repeated here.

[0126] Exemplarily, the method further includes: in response to the electrocoagulation cutting function of the electrocoagulation forceps being turned on, controlling the nerve detection function of the electrocoagulation forceps to be turned off.

[0127] Optionally, the method further includes: after the timing time reaches the target delay time, controlling the electrocoagulation forceps to issue a first prompt message, wherein the first prompt message is used to indicate that a nerve monitoring function of the electrocoagulation forceps is turned on.

[0128] Optionally, the method also includes: when the timing time does not reach the target delay time, controlling the electrocoagulation forceps to issue a second prompt message, the second prompt message being used to indicate that the nerve monitoring function of the electrocoagulation forceps is not turned on; the second prompt message is different from the first prompt message.

[0129] It should be noted that the description and principles of the relevant elements involved in each step of the above method can be referred to the description of the above hardware embodiment, and will not be repeated here.

[0130] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.

[0131] See also Figure 7 As shown, in actual application, the high-frequency generator device 200 can be connected to a foot switch, so that when a surgery (such as thyroid surgery) is performed, the user (such as a doctor) steps on the foot switch, and the high-frequency excitation identification circuit 20 generates an induction signal, and the controller 30 determines that the electrocoagulation and cutting function of the electrocoagulation forceps 100 is turned on according to the induction signal, and then can generate a second control signal to control the nerve monitoring switching circuit 40 to stop outputting the nerve stimulation signal of the nerve monitor 300. At this time, the electrocoagulation and cutting function of the electrocoagulation forceps 100 is turned on, and the nerve monitoring function is turned off. The electrocoagulation forceps can perform coagulation hemostasis and cutting operations.

[0132] When the user (such as a doctor) releases the foot switch, the high-frequency excitation identification circuit 20 will not generate an induction signal, or will generate a weak induction signal. At this time, the controller 30 determines that the electrocoagulation and cutting function of the electrocoagulation forceps 100 is turned off, and then starts timing and determines the target delay time, and generates a first control signal to control the nerve monitoring switching circuit 40 to output the nerve stimulation signal of the nerve monitor 300. At this time, the electrocoagulation and cutting function of the electrocoagulation forceps 100 is turned off, and the nerve monitoring function is turned on. After the timing time reaches the target delay time, the controller generates a first prompt signal; the first prompt signal is used to instruct the prompt device to generate a first prompt information, and the first prompt information is used to prompt the user that the electrocoagulation forceps can perform nerve monitoring, so that the probability of nerve tissue damage caused by overheating of the forceps tip can be reduced.

[0133] In this way, when the tip 101 of the electrocoagulation forceps 100 is close to the nerve to dissect and separate the tissue, before coagulation and hemostasis and cutting of the tissue, the user can use the nerve detection function after receiving the first prompt information. The stimulation current signal of the nerve monitoring instrument 300 will be transmitted to the tissue part that needs to be monitored through the tip 101 of the forceps, and then the signal receiving needle electrode inserted into the subcutaneous tissue will transmit the electromyographic feedback signal generated by the current stimulation of the tissue back to the nerve monitor 300. If the monitor screen does not display the nerve electromyographic waveform and the prompt sound of the vocal cord activity reaction is not heard, it can be considered that there are no nerves in the tissue of the detection area. At this time, the necessary surgical operations can be performed with confidence. If the nerve electromyographic waveform is seen and the electromyographic activity prompt sound is heard, it means that there are nerves passing through the tissue in this area, and the nerves need to be carefully separated and dissected to avoid nerve damage during the operation.

[0134] The electrocoagulation forceps 100 and the control method of the electrocoagulation forceps provided in the embodiment of the present disclosure, when it is determined that the electrocoagulation and cutting function of the electrocoagulation forceps 100 is converted from the on state to the off state, start timing and determine the target delay time, and generate a first control signal to control the electrocoagulation forceps 100 to output the nerve stimulation signal of the nerve monitor 300; after the timing time reaches the target delay time, the controller 30 also generates a first prompt signal to instruct the prompt device to generate a first prompt information, and then prompt the user. In this way, automatic switching between the electrocoagulation and cutting function and the nerve detection function can be achieved without the need for manual switching by the user, thereby improving the convenience of operation. In addition, when the target delay time is reached after the electrocoagulation and cutting function is turned off, the first prompt signal is generated to instruct the prompt device to generate the first prompt information, and then the user is reminded, which can reduce the occurrence of nerve tissue damage due to overheating of the forceps tip, thereby reducing the probability of nerve tissue damage during the switching process.
