Description
Technical Field
[0001] This application belongs to the field of medical technology, and in particular relates to an electrosurgical host, an electrosurgical system and a control method. Background Technology
[0002] A high-frequency electrosurgical unit (HFES) is a surgical device used to cut and coagulate human tissue. It boasts advantages such as rapid cutting speed, excellent hemostasis, simple operation, and safety. Clinically, HFES can significantly shorten surgical time, reduce blood loss and transfusion volume, thereby lowering complications and surgical costs. With its increasing efficiency, safety, and flexibility, it is gradually replacing traditional surgical instruments and becoming an indispensable part of the surgical process. HFES is widely used in various departments, including hepatobiliary surgery, gastrointestinal surgery, and gynecology. Different departments employ various surgical procedures, such as cholecystectomy, partial splenectomy, and liver lesion resection. Different procedures target various tissue types, including muscle, fat, mesangial tissue, and fascia. Different tissues require different power ranges. Therefore, electrosurgical manufacturers currently offer different output modes (functions) based on the characteristics of different departments. These include modes such as monopolar automatic cutting, bloodless electrosurgical cutting, high-energy electrosurgical cutting, pure cutting, mixed cutting, monopolar electrocoagulation, electrocautery, and bipolar electrocoagulation. Each function of electrosurgical equipment has multiple power levels, ranging from as few as 5 to as many as hundreds. This means that doctors and nurses need professional training to become familiar with the corresponding modes and power levels required for different surgical procedures and tissues. They also need to manually adjust the corresponding functions before and during surgery. This adjustment method is time-consuming and laborious, prolonging the operation time.

[0057] Before introducing the embodiments of this application, a brief overview of the related technologies and technical problems is provided. A high-frequency electrosurgical unit is a surgical device used to cut and coagulate human tissue. It has advantages such as fast cutting speed, good hemostasis, simple operation, safety, and convenience. Clinically, the use of high-frequency electrosurgical units can significantly shorten surgical time, reduce patient blood loss and transfusion volume, thereby reducing complications and surgical costs. With its high efficiency, safety, and flexible application range expanding, it is gradually replacing traditional surgical instruments and becoming an indispensable part of the surgical process.
[0058] Figure 1 This is a schematic diagram of the structure of an electrosurgical system in the related technology, such as... Figure 1 As shown, the electrosurgical system includes electrosurgical equipment, connecting cables, and instruments. The electrosurgical equipment consists of internal hardware circuitry, software programs, a touchscreen display, and an instrument interface. The instrument interface connects to the corresponding cables. For unipolar operation, the equipment generates high-frequency, high-voltage alternating current, which is transmitted to the instrument via a unipolar cable. Acting on human tissue, the current returns to the equipment via a neutral electrode and neutral cable. The internal detection circuit of the equipment can detect the voltage and current at both ends of the output circuit. For bipolar operation, the high-frequency, high-voltage alternating current reaches one electrode of the bipolar instrument through one path in the bipolar cable. The current passes through that electrode, the patient's treatment site, and then through the other electrode of the instrument, returning to the equipment via another branch of the bipolar cable. Similarly, the internal detection circuit of the equipment can calculate the voltage delivered to both electrodes and the current flowing through the patient. Simultaneously, effective analysis of the voltage and current determines the load impedance acting on the instrument's front end. Changes in impedance adjust the output within the power, voltage, and current range corresponding to the set mode and setting, enabling the instrument to perform electrocautery and electrocoagulation functions normally.
[0059] However, in daily use, high-frequency electrosurgical units are widely used in various departments, such as hepatobiliary surgery, gastrointestinal surgery, and gynecology. Different departments perform a wide variety of surgical procedures, such as cholecystectomy, partial splenectomy, and liver resection. Different procedures target different tissue types, such as muscle, fat, mesangial tissue, and fascia. Different tissues require different power ranges. Therefore, electrosurgical unit manufacturers currently offer different output modes (functions) based on the characteristics of different departments, such as monopolar automatic cutting, bloodless electrosurgical cutting, high-energy electrosurgical cutting, pure cutting, mixed cutting, monopolar electrocoagulation, electrocautery, and bipolar electrocoagulation modes. Figure 2 This is a schematic diagram of an interface for adjusting the output mode and gear position of an electrosurgical system provided in related technologies, such as... Figure 2As shown, electrosurgical equipment has numerous settings for each function, ranging from as few as five to hundreds of settings per mode. This necessitates specialized training for doctors and nurses in clinical practice to familiarize themselves with the appropriate modes and settings for different surgical procedures and tissues. Manual adjustments to these functions are required before and during surgery, a time-consuming and laborious process that prolongs the operation. Inappropriate parameter settings often lead to problems such as poor cutting, insufficient coagulation, or excessive carbonization. Furthermore, current high-frequency electrosurgical equipment typically employs a constant current, constant power, and constant voltage output control strategy. While ensuring effective output at the current stage, this strategy neglects the detailed control of energy output during surgery, resulting in excessively high power output and excessive tissue thermal damage. This not only prolongs the operation but also affects surgical quality and increases postoperative healing time.
[0060] Based on the problems in related technologies, this application provides an electrosurgical host comprising: a function modulation panel and a user interface. The function modulation panel has an intelligent switching control, which is used to set the electrosurgical host to intelligently switch its working mode and / or working level according to the feedback electrical signal received in real time from the user interface. The user interface is used to connect to electrosurgical instruments and to transmit electrical energy to the electrosurgical instruments and receive feedback electrical signals from the electrosurgical instruments. The working modes include pure cutting mode, non-pure cutting mode, pure electrocoagulation mode, and non-pure electrocoagulation mode, and each working mode includes multiple different working levels.
[0061] In this embodiment, the function modulation panel is a control component of the electrosurgical host. It functions like an operating console with various control elements, including an intelligent switching control. This panel allows adjustment of the electrosurgical host's operating status. The intelligent switching control is a key component of the function modulation panel. Its main function is to enable the electrosurgical host to automatically change its operating mode and / or operating level based on electrical signals fed back from the user interface. For example, when electrosurgical instruments encounter different tissue types or operational situations during operation, the feedback electrical signals change, and the intelligent switching control adjusts the host's operating status accordingly.
[0062] In this embodiment, if the electrosurgical unit only has intelligent control in the electrosurgical host, the intelligent switching control is the electrosurgical function activation control; if the electrosurgical control also includes manual adjustment of modes and gears, then this intelligent switching control is a switching control used to switch between intelligent and manual modes under the electrosurgical function. When the electrosurgical unit can be manually controlled, the function modulation panel can also be equipped with settings for the working mode and the working gear.
[0063] In this embodiment, the user interface is the connection between the electrosurgical host and the electrosurgical instruments. On one hand, it serves as a power transmission mechanism, transmitting the electrical energy generated by the electrosurgical host to the electrosurgical instruments, enabling the instruments to perform operations such as cutting or electrocoagulation. On the other hand, it can also receive electrical signals fed back from the electrosurgical instruments. These feedback electrical signals contain various information about the electrosurgical instruments during operation, such as the contact status between the instruments and tissues, and the tissue's electrical impedance.
[0064] In this embodiment, the electrosurgical instruments are tools used directly in surgical procedures, such as electrosurgical knives and electrocoagulators. These instruments are connected to the electrosurgical host via a user interface, receive electrical energy from the host to operate, and simultaneously feed back relevant information about their operation to the user interface in the form of electrical signals.
[0065] In this embodiment, in pure cutting mode, the electrical energy output by the electrosurgical unit is mainly used to cut tissue, enabling precise tissue cutting with clean incisions. For example, in delicate surgical procedures such as ophthalmology or plastic surgery, where high precision in tissue cutting is required, pure cutting mode may be used. In non-pure cutting mode, in addition to cutting, other functions may be included, such as hemostasis or other physical effects on the tissue. For example, in general surgery, reducing bleeding while cutting tissue may be desired, thus using non-pure cutting mode. Pure electrocoagulation mode primarily uses electrical energy to coagulate tissue, achieving hemostasis. For example, in cases of small blood vessel bleeding during surgery, pure electrocoagulation mode can coagulate the blood vessel, thereby stopping the bleeding. Non-pure electrocoagulation mode is similar to non-pure cutting mode, and may also have other functions during electrocoagulation, such as promoting tissue adhesion or adjusting tissue morphology during electrocoagulation.
[0066] In this embodiment, each working mode includes multiple different working levels, which represent different levels of electrical energy output from the electrosurgical unit. For example, in pure cutting mode, lower levels may be suitable for cutting thinner, softer tissues, while higher levels may be used for cutting thicker, harder tissues. Different working modes can correspond to different levels of electrical energy.
[0067] In this embodiment, when the electrosurgical instrument is in operation, it generates feedback electrical signals, which are transmitted back to the electrosurgical host via the user interface. For example, when the electrosurgical instrument is cutting tissue, if it encounters a change in the tissue's impedance (such as changing from cutting soft tissue to cutting hard tissue), the frequency, amplitude, and other parameters of the feedback electrical signals will change accordingly. After the electrosurgical host receives these feedback electrical signals, it can calculate the real-time impedance and the real-time impedance change rate based on an algorithm, and then switch the operating mode and / or operating level based on the real-time impedance and the real-time impedance change rate.
[0068] In this embodiment, if it is determined that a change in the working mode is needed, such as switching from a pure cutting mode to a non-pure cutting mode, or if only the working level needs to be adjusted, such as switching from a low level to a high level, the control unit will adjust the mode and intensity of the power output accordingly. The adjusted power output of the electrosurgical host is transmitted to the electrosurgical instruments through the user interface, thereby adjusting the working state of the electrosurgical instruments to adapt to different situations during surgery.
[0069] The adjusted power output of the electrosurgical host is transmitted to the electrosurgical instruments through the user interface, thereby adjusting the working status of the electrosurgical instruments to adapt to different situations during surgery.
[0070] This application provides an electrosurgical host, which includes a function modulation panel and a user interface. The function modulation panel has an intelligent switching control, which is used to set the electrosurgical host to intelligently switch its working mode and / or working level based on the feedback electrical signals received from the user interface in real time. The user interface is used to connect to electrosurgical instruments and to transmit power to the electrosurgical instruments and receive feedback electrical signals from the electrosurgical instruments. It can automatically switch the working mode and / or working level of the electrosurgical host based on the feedback electrical signals during the operation, so that doctors or nurses do not need to know the corresponding mode and level that need to be changed for different surgical procedures and different tissues, and do not need to make manual adjustments, thereby reducing the operation time.
[0071] In some embodiments, the function modulation panel further includes a display control for the working mode and working level, the display control being configured to display the status information of the working mode and working level of the electrosurgical host in real time when the intelligent switching control is activated.
[0072] In this embodiment, the display control is a component on the function modulation panel, and its main function is to visually present the working mode and working speed information of the electrosurgical host. It acts like an information window, allowing users (usually medical staff) to intuitively understand the current working status of the electrosurgical host.
[0073] In this embodiment, when the intelligent switching control is activated, the control system inside the electrosurgical unit sends the current working mode (e.g., pure cutting mode, non-pure cutting mode, pure electrocoagulation mode, or non-pure electrocoagulation mode) and working level information to the display control. The display control can display this status information in various forms. For example, it can be a liquid crystal display (LCD) screen that clearly displays the current working mode and level through text, such as "Current working mode: pure cutting mode, working level: 3". Alternatively, it can be a series of indicator lights, with different colored indicator lights representing different working modes, and the flashing frequency or brightness of the indicator lights representing different working levels. For example, a solid green indicator light represents pure cutting mode, while a rapidly flashing green indicator light may represent a higher working level.
[0074] In this embodiment, during the surgery, the intelligent switching control adjusts the working mode and speed of the electrosurgical host in real time based on the feedback electrical signals from the electrosurgical instruments, and the display control also needs to update the displayed information in real time. For example, when the electrosurgical host switches from pure cutting mode to pure electrocoagulation mode and the speed is adjusted from level 3 to level 2, the display control can update the displayed content in a very short time so that medical staff can understand the changes in the working status of the equipment in a timely and accurate manner.
[0075] In some embodiments, the electrosurgical device further includes: a controller configured to generate preset electrical energy according to the current operating mode and operating level of the electrosurgical host, output preset electrical energy to the electrosurgical instrument through a user interface, and obtain real-time feedback electrical signals from the user interface; calculate the real-time impedance and real-time impedance change rate of the target tissue acted upon by the electrosurgical instrument based on the real-time feedback electrical signals from the user interface; and determine whether to switch the current operating mode and / or operating level based on the real-time impedance, the real-time impedance change rate, and a first preset condition.
[0076] In this embodiment, different working modes and power levels correspond to different electrical energy. After determining the current working mode and power level, the output is based on a preset electrical energy. For example, in the high power level of the pure cutting mode, the preset electrical energy parameters such as voltage and current will be relatively high to meet the needs of rapid tissue cutting; while in the low power level of the pure electrocoagulation mode, the preset electrical energy parameters will be adjusted to a lower value suitable for tissue coagulation and hemostasis.
[0077] In this embodiment, the controller can generate preset electrical energy based on the currently set working mode and speed through internal circuitry and algorithms. This process involves controlling the power module, such as adjusting parameters like voltage and current, to ensure the output electrical energy meets preset requirements. The preset electrical energy is then transmitted to the electrosurgical instruments via a user interface.
[0078] In this embodiment, the user interface transmits feedback electrical signals from the electrosurgical instruments back to the controller in real time. These feedback electrical signals contain information about the target tissue's response to electrical energy, such as voltage drop and current changes. This information forms the basis for calculating real-time impedance and the rate of change of real-time impedance.
[0079] In this embodiment, the controller uses voltage and current information from the feedback electrical signal to calculate the real-time impedance and real-time impedance change rate of the target tissue being acted upon by the electrosurgical instrument. The target tissue refers to the tissue being acted upon by the electrosurgical instrument, such as human tissue being cut or electrocoagulated during surgery. Impedance is an electrical concept that represents the resistance to current. Real-time impedance is the degree of resistance of the tissue to electrical energy transmission, calculated in real time through the feedback electrical signal during the surgical procedure. Different types of tissues (such as muscle, fat, blood vessels, etc.) have different impedance characteristics, and the impedance of the same tissue may also differ under different states (such as normal, diseased, congested, etc.). The real-time impedance change rate refers to the degree of change of the real-time impedance of the target tissue per unit time. For example, if the electrosurgical instrument transitions from one tissue type to another during tissue cutting, or if the state of the tissue changes, the real-time impedance will change, and the real-time impedance change rate can reflect the speed of this change.
[0080] In this embodiment, the controller can determine whether to switch the current working mode and / or working level based on the real-time impedance, the real-time impedance change rate and the first preset condition.
[0081] In some embodiments, the electrosurgical host further includes a memory storing a first preset condition, the first preset condition including an impedance threshold range, a plurality of first impedance change rate threshold ranges corresponding to each impedance threshold range, and a second impedance change rate threshold range.
[0082] In this embodiment, the impedance threshold range is a pre-set range of impedance values, and the impedance change rate threshold range corresponding to each impedance threshold position is also a pre-set range, used to measure the rate of change of impedance in real time. The impedance threshold range refers to the upper and lower limits of impedance values set to distinguish different tissue types or surgical stages. For example, low impedance may represent adipose tissue, while high impedance may represent bone or muscle tissue. The first impedance change rate threshold range is used to determine whether the tissue state is stable during the current surgical process and whether the operating level of the electrosurgical host needs to be adjusted. The second impedance change rate threshold range is used to determine whether any abnormalities have occurred during the current surgical process and whether a switch to a different operating mode is necessary.
[0083] In some embodiments, the controller may determine whether to switch the current operating mode and / or operating level based on real-time impedance, real-time impedance change rate, and a first preset condition, including:
[0084] The system compares the real-time impedance with the impedance threshold range. When the real-time impedance is within the impedance threshold range and the real-time impedance change rate is within the first impedance change rate threshold range, the system determines whether the host should maintain the current working level, increase the current working level, or decrease the current working level. When the real-time impedance is less than the impedance threshold range, the system switches the current working mode and working level of the electrosurgical host according to the impedance change rate threshold range corresponding to the real-time impedance change rate.
[0085] In this embodiment, after the controller obtains the real-time impedance value, it compares it with the stored impedance threshold range. When the real-time impedance is within the impedance threshold range, it indicates that there is no sudden bleeding at the cutting site or that hemostasis has been achieved. The controller then checks the impedance change rate threshold range within which the real-time impedance change rate falls. In this embodiment, different impedance change rate threshold ranges can correspond to different power application effects. By using the impedance change rate range within which the real-time impedance change rate falls, the corresponding different power application effects can be determined. For example, different impedance change rate threshold ranges can correspond to insufficient power resulting in no cutting, normal power resulting in normal cutting, and excessive power resulting in excessively fast cutting speed.
[0086] In this embodiment, if the real-time impedance change rate corresponds to the threshold range of impedance change rate where power is too low and cutting is not possible, then it is determined that power is too low and cutting is not possible, and the current operating level can be increased. If the real-time impedance change rate corresponds to the threshold range of impedance change rate where power is normal and cutting is normal, then the current operating level is maintained. If the impedance change rate corresponds to the threshold range of impedance change rate where power is too high and cutting speed is too fast, then the current operating level can be decreased.
[0087] For example, the first impedance change rate threshold range has a first range A, a second range B, and a third range C. The first range A corresponds to low power and no cutting, the second range B corresponds to normal power and normal cutting, and the third range C corresponds to excessive power and excessive cutting speed. At this time, if the real-time impedance change rate is within the first range A, the gear needs to be increased. If the real-time impedance change rate corresponds to the second range B, the current working gear needs to be maintained. If the real-time impedance change rate corresponds to the third range C, the current working gear needs to be decreased.
[0088] In this embodiment, when the real-time impedance is less than the impedance threshold range and the real-time impedance change rate is within the second impedance change rate threshold range, for example, when there is sudden bleeding in the target tissue, the current working mode and setting of the electrosurgical host are switched. For example, if the current working mode is cutting, and the real-time impedance is determined to be less than the impedance threshold range, it switches to electrocoagulation mode and the setting switches to the default setting of electrocoagulation mode. When the real-time impedance is greater than the impedance threshold range and the real-time impedance change rate is within the second impedance change rate threshold range, for example, when the bleeding in the target tissue has been basically stopped and there is no obvious bleeding, resulting in a significant increase in impedance, the current working mode and setting of the electrosurgical host are switched. For example, if the current working mode is electrocoagulation, and the real-time impedance is determined to be greater than the impedance threshold range, it switches to cutting mode and the setting switches to the default setting of cutting mode.
[0089] In some embodiments, the controller is further configured to: control the electrosurgical host to switch working modes when the current working level is the minimum level of the corresponding working mode and it is determined based on the real-time impedance change rate that the current working level needs to be lowered; and control the electrosurgical host to switch working modes when the current working level is the maximum level of the corresponding working mode and it is determined based on the real-time impedance change rate that the current working level needs to be raised.
[0090] In this embodiment, the current operating gear is compared with the minimum and maximum gears of the corresponding operating mode. This comparison process is used to determine whether there is still room to adjust the gear within the same operating mode. If adjustment is needed, but there are no higher or lower gears available within the same operating mode, then it is necessary to switch to another operating mode.
[0091] In this embodiment, when the current operating level of the electrosurgical unit is already the lowest level in the corresponding operating mode, if it is determined based on the real-time impedance change rate that further reduction in power or energy output is needed (i.e., lowering the level), then since there are no lower levels available, the system will switch to a different operating mode. This new operating mode typically has a lower default power or energy output, thereby meeting the requirement of reduced output.
[0092] In this embodiment of the application, when the real-time impedance change rate is less than the impedance threshold range and the real-time impedance change rate is within the second impedance change rate threshold range, it is determined that there is bleeding in the target tissue.
[0093] In this embodiment, when the real-time impedance is less than the impedance threshold range, and the real-time impedance change rate is within the second impedance change rate threshold range, it means that the impedance of the target tissue has undergone a relatively significant change. This significant change may be caused by a substantial change in the internal state of the tissue, such as changes in the electrical properties of the tissue due to blood outflow.
[0094] In this embodiment of the application, by comprehensively judging the real-time impedance and the real-time impedance change rate, it is possible to monitor whether bleeding occurs in the target tissue in scenarios such as electrosurgery, so as to take corresponding measures in a timely manner, such as switching the working mode to stop bleeding.
[0095] Taking the current working mode as the first working mode and the current working gear as the first working gear as an example, when the output power of the first working mode and the first working gear is applied to the target tissue, the feedback electrical signal during this process is acquired, and the real-time impedance and the real-time impedance change rate are determined based on the feedback electrical signal; the presence of a coagulation effect can be determined based on the real-time impedance and the real-time impedance change rate; when the coagulation effect does not meet the requirements, and the gear corresponding to the first working mode is the maximum gear, the first working mode is switched to the second working mode, wherein the coagulation ability of the second working mode is greater than that of the first working mode.
[0096] In this embodiment, different impedance information reflects different states of the target tissue during the coagulation process. By further analyzing the first impedance information and comparing it with the impedance characteristics under known coagulation states, the coagulation effect can be determined. An unsatisfactory coagulation effect may refer to a coagulation rate that is too slow, failing to achieve effective hemostasis within the expected time, or incomplete coagulation with signs of continued bleeding. To enhance coagulation ability, the first working mode is switched to a second working mode. This switch is made because the coagulation ability of the second working mode is greater than that of the first working mode. In the second working mode, the device adjusts the output power parameters and electrical waveform to more effectively promote protein coagulation in the blood, thereby improving the coagulation effect and better achieving hemostasis.
[0097] In this embodiment, when the current operating level of the electrosurgical unit is already the maximum level under the corresponding operating mode, if it is determined based on the real-time impedance change rate that further power or energy output is needed (i.e., upgrading to a higher level), then since there are no higher levels available, the system will switch to a different operating mode. This new operating mode typically has a higher default power or energy output, thereby meeting the need for increased output.
[0098] In this embodiment, the electrosurgical host can automatically adjust the working mode and / or working level according to the real-time situation during the operation, thereby optimizing the surgical effect and reducing potential risks.
[0099] In some embodiments, the controller is further configured to: when the current operating mode is the cutting mode, the real-time impedance is greater than the impedance threshold range, and the real-time impedance change rate is within the second impedance change rate threshold range, switch the operating mode to a first operating mode, the first operating mode having at least the cutting function.
[0100] In this embodiment, when the electrosurgical unit is in cutting mode, its main function is to cut tissue using high-frequency electrical energy. However, during the procedure, monitoring the real-time impedance of the target tissue can determine whether bleeding is occurring. Changes in real-time impedance are a crucial indicator because the presence of blood alters the tissue's electrical properties, causing impedance changes. For example, blood's conductivity differs from normal tissue; bleeding may increase the conductivity of the tissue, resulting in a decrease in real-time impedance. Once bleeding is confirmed in the target tissue, the device switches to a first operating mode, which at least provides a coagulation function.
[0101] In this embodiment, different real-time impedances and rates of change of real-time impedance can reflect different states of the target tissue during the coagulation process, thereby allowing for the determination of whether coagulation is complete. Generally, if the real-time impedance exhibits a relatively stable state that matches the expected electrical characteristics of the target tissue after coagulation, it can be preliminarily determined that coagulation is complete. For example, after coagulation, because components such as proteins in the blood have coagulated, the electrical characteristics of the tissue will change significantly, typically manifested as an impedance value rising to a relatively stable level, i.e., greater than the impedance threshold range. In this case, it is necessary to switch the working mode back to the original cutting mode and the corresponding setting. The reason for switching back to the cutting mode is that in previous surgical operations, the cutting mode was mainly used for cutting the target tissue. After coagulation and handling of bleeding, it is necessary to continue surgical operations such as tissue cutting according to the original plan to advance the surgical process. Therefore, it is necessary to restore the original cutting mode and corresponding setting to continue to complete the surgical task efficiently and accurately.
[0102] In some embodiments, the controller is further configured to: issue an interrogation power and determine the initial impedance of the target tissue based on the feedback electrical signal of the interrogation power detected by the detection module; determine the tissue type of the target tissue based on the initial impedance and a second preset condition; determine the operating mode of the host and the corresponding operating level based on the tissue type; and control the electrosurgical host to output preset power to the electrosurgical instruments in the operating mode and operating level; the electrosurgical host further includes a memory that stores the second preset condition, which includes a correspondence between different tissue types and impedance ranges.
[0103] In this embodiment, the electrosurgical host emits an interrogation signal, which is an electrical signal used to detect the characteristics of the target tissue. Feedback signals from the interrogation signal can be obtained from the electrosurgical instrument via a user interface. These feedback signals may include voltage and current. The initial impedance of the target tissue can be determined by analyzing these feedback signals.
[0104] In this embodiment, the second preset condition includes the correspondence between different tissue types and impedance ranges. Once the initial impedance of the target tissue is obtained, the tissue type of the target tissue can be determined based on this correspondence. For example, if the initial impedance value is in the range of 100-200 ohms, and the second preset condition specifies the tissue type corresponding to this range, then the target tissue can be determined.
[0105] In this embodiment, once the tissue type is determined, the operating mode and corresponding power level of the electrosurgical host can be determined based on the tissue type. Different tissue types have different tolerances and responses to electrical energy, so different operating modes and power levels are required for effective electrosurgical operations. For example, a lower power level may be needed for adipose tissue, while a relatively higher power level may be needed for muscle tissue. Then, the electrosurgical host outputs preset electrical energy to the electrosurgical instruments according to the determined operating mode and power level to perform electrosurgical operations such as cutting and coagulation.
[0106] Based on the foregoing embodiments, this application provides a specific example where, for unipolar output, the electrosurgical host emits an interrogation energy. The power and voltage of this interrogation energy are significantly lower than those used for cutting and electrocoagulation, for example, 100mW, 5V. This interrogation energy can be used to determine whether the instrument is currently unloaded, in contact with tissue (tissue type), or short-circuited. The detection method involves using voltage and current transformers built into the host and inputting the data into the controller within the electrosurgical host for relevant calculations and judgments. In the initial output state, when unloaded (i.e., no tissue is clamped between the surgical electrode and the neutral electrode), the voltage between the monopolar instrument and the neutral electrode is the unloaded voltage of 5V, the current is approximately 0A, and the power is approximately 0W. When short-circuited (i.e., the surgical electrode and the neutral electrode are in contact, or there is a highly conductive material between them, such as a metal bridging the gap, or the environment is saline), the voltage between the monopolar instrument and the neutral electrode is the short-circuit voltage of 0V, and the output power is approximately 0W. When tissue is clamped between the surgical electrode and the neutral electrode, the tissue type can be determined based on the initial impedance. When the impedance is relatively low, such as 20–100 ohms, it can be considered that there is muscle tissue between the monopolar instrument and the negative electrode plate. In this case, a relatively small output is required, such as 300V, 40W, corresponding to the pure output of a traditional electrosurgical unit. In the cutting mode, the lower setting is used. When the impedance is relatively high, such as greater than 1000 ohms, the tissue between the monopolar instrument and the neutral electrode can be considered to have high impedance, such as adipose tissue or fascia. In this case, a higher power output is required, such as 80-100W, and a higher output voltage can be set, with a larger peak voltage, such as 1500V. This corresponds to the bloodless electrosurgical cutting mode of traditional electrosurgery, at the lower setting. In this mode, a discharge is generated, which promotes cutting and reduces cutting resistance. Using relatively higher voltage and power for high-impedance tissue can avoid mechanical pulling caused by insufficient output power and voltage, resulting in greater thermal and mechanical damage. When the impedance is less than 20 ohms, it is considered to be in a blood environment, or there is severe bleeding. A high current output can be used to quickly dry the blood, such as in the jet electrocoagulation mode. Figure 3 This is a schematic diagram of the output of jet electrocoagulation provided in an embodiment of this application.
[0107] In some embodiments, during the high-frequency electrosurgical cutting of clotted tissue, the working mode and / or working level can be further adjusted according to the real-time impedance change rate of the tissue. For example, if the initial impedance is low, such as around 100 ohms, it is identified as muscle. During the output process, if the impedance rapidly rises to above 1000 ohms within 50ms, it can be considered that the electrosurgical is cutting the tissue and the cutting energy is sufficient. During this output process, the impedance changes rapidly within the range of 50 ohms to 2000 ohms, dynamically changing according to the movement of the electrosurgical. When the initial impedance is greater than 1000 ohms, it is identified as fat or fascia tissue. During the output process, if the impedance changes back and forth between 1000 ohms and 5000 ohms in a short period of time, it can be considered that the electrosurgical is cutting fat tissue. The initial impedance for fat is around 1000 ohms. After the tissue is cut and denatured, the impedance rapidly rises to above 3000 ohms. As the electrosurgical pen moves, the tissue contacted by the electrode changes to new fat tissue. At this time, the impedance drops back to around 1000 ohms. This process and trend can be defined as the cutting of fat tissue in this surgical stage. When the output energy is insufficient, the real-time impedance change rate can be detected as slow. If the slope of the impedance change is greater than a certain set value, the output energy level can be appropriately increased, that is, the working level can be increased. Furthermore, depending on gender and age, older patients or those with lower body water content have higher tissue impedance, requiring higher power or voltage for cutting. The electrosurgical unit determines the default setting based on the collected voltage and current information to assess tissue impedance. For example, when the impedance fluctuates between 80 and 3000 ohms, a lower automatic electrosurgical energy output is provided, similar to the low-level pure cutting of commonly used electrosurgical devices. When the impedance fluctuates between 200 and 3500 ohms, a relatively higher automatic electrosurgical energy output is provided, similar to the medium-level pure cutting of commonly used electrosurgical devices. The device provides appropriate power output based on the impedance variation range and rate of change. It integrates traditional electrosurgical settings and power selection into the device. Through hardware electrical signal detection and software analysis, it determines the tissue type, the required energy type, and predicts the upcoming impedance change trend. By detecting the rate of change and phase difference of voltage and current during the output process, it assesses the current cutting coagulation effect and adjusts the output energy in real time. Based on the initial and process tissue state assessment, it achieves intelligent adjustment of energy output levels, improving output efficiency and reducing thermal damage.
[0108] For bipolar electrosurgical units, the internal input / output circuitry provides high-frequency electrical energy to the tissue through two pointed electrodes, causing the blood vessels or proteins between the electrodes to dehydrate and coagulate, achieving hemostasis. Its detection circuitry is simpler and clearer. The impedance of bipolar-clamped tissue is relatively low; fresh tissue typically has impedances ranging from tens to hundreds of ohms. When clamping vascular tissue, the initial impedance is approximately 20-50 ohms, requiring a small voltage and a large current output to provide a fast and stable effect. When clamping muscle tissue with small capillaries between the two bipolar electrodes, the impedance is typically 50-100 ohms, requiring a relatively large voltage and a relatively low current, necessitating a rapid electrocoagulation effect with a shallower coagulation depth compared to vascular tissue. When clamping adipose tissue, a larger voltage and power are needed to achieve a better coagulation effect. During coagulation, the impedance of vascular tissue changes slowly, followed by fat, while the impedance of muscle tissue changes rapidly. The type of tissue is determined by the range of tissue impedance changes, and appropriate energy is provided, which corresponds to different output modes and levels of common electrosurgical units. By querying the power supply and monitoring the impedance in real time during use, the tissue can be automatically identified. During the output process, analogous to monopolar, the device detects the rate of impedance change between the two bipolar instruments and automatically adjusts the output effect. Once the tissue impedance reaches a certain threshold, the energy output is automatically stopped, completing the coagulation process.
