Technical Field

[0002] The present application relates to the field of data processing, and in particular to an ultrasonic scalpel energy output control system, an ultrasonic scalpel energy output control method, and a computer-readable storage medium. Background Art

[0003] An ultrasonic scalpel is an energy device used in surgical scenarios. It converts electrical energy into mechanical vibrations and transmits them to the blade head. The vibrating blade head comes into contact with the tissue and uses mechanical impact to achieve the purpose of switching tissues or coagulating tissues.

[0004] During surgery, the surgeon uses an ultrasonic scalpel to deliver a fixed amplitude energy output. If this constant amplitude is used in all situations, surgical quality can be compromised. For example, during a surgical procedure like perforation, if the surgeon continues to deliver energy at the fixed amplitude after perforating the tissue, there is a risk of accidental damage to other tissue when retrieving the scalpel tip, compromising surgical quality.

[0037] The ultrasonic scalpel energy output control system, ultrasonic scalpel energy output control method and computer readable storage medium in the embodiments of the present application will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0038] FIG1 is a schematic diagram of the structure of an ultrasonic scalpel energy output control system provided in an embodiment of the present application, and FIG2 is another schematic diagram of the structure of an ultrasonic scalpel energy output control system provided in an embodiment of the present application.

[0039] As shown in Figure 1, the ultrasonic scalpel energy output control system 100 includes an ultrasonic host 110, a transducer 120, an ultrasonic scalpel 130 and a measuring unit 140, wherein the ultrasonic host 110 is connected to the transducer 120, the transducer 120 is connected to the ultrasonic scalpel 130, and the measuring unit 140 is connected to the ultrasonic host 110.

[0040] As shown in FIG2 , the ultrasound main unit 110 includes a controller 111 and a drive unit 112, wherein the drive unit 112 is connected to the controller 111. The ultrasonic scalpel 130 includes a scalpel head 131. The ultrasonic scalpel 130 also includes a scalpel handle assembly 132. Furthermore, the ultrasonic scalpel 130 also includes a sensor 133. The sensor 133 is in communication with the measurement unit 140, and the scalpel head 131 is connected to the scalpel handle assembly 132.

[0041] The various objects / components / elements in the ultrasonic scalpel energy output control system 100 will be further introduced below.

[0042] The blade head 131 is the execution component of the ultrasonic scalpel 130. Specifically, surgical operations including but not limited to punching, back cutting, cutting, clamping cutting or coagulation can be performed by the blade head 131. During the surgical operation, the blade head 131 contacts the patient's tissue.

[0043] The cutting head 131 is used to process tissue. The cutting head 131 includes a first cutting head assembly and a second cutting head assembly. The first cutting head assembly and the second cutting head assembly move relative to each other around an axis so that the cutting head 131 changes between a first cutting head state and a second cutting head state. The first cutting head state is an open state, and the second cutting head state is a closed state.

[0044] The handle assembly 132 is used to connect the transducer 120 and the cutter head 131 .

[0045] Sensor 133 is used to generate a sensing signal based on the cutting head status of cutter head 131. There may be one or more sensors 133. Sensor 133 may be disposed in handle assembly 132 and / or in cutter head 131. The placement of sensor 133 is not specifically limited.

[0046] The sensor 133 can be any contact sensor, such as a pressure sensor. Accordingly, the sensor 133 can be disposed in the handle assembly 132 or in the cutter head 131. The sensor 133 can also be any proximity sensor, such as a distance-measuring proximity sensor. Accordingly, the sensor 133 can be disposed in the cutter head 131. The sensor 133 can also be any electrical sensor, such as a Hall effect sensor, or any mechanical sensor, such as a switch sensor. The specific nature of the sensor 133 is not specifically limited.

[0047] No matter where the sensor 133 is set, and no matter what kind of sensor the sensor 133 is, its corresponding function remains unchanged.

[0048] The transducer 120 is configured to convert received electrical energy into kinetic energy and transmit the kinetic energy to the cutter head 131, for example, via the handle assembly 132. Specifically, the piezoelectric ceramic in the transducer 120 converts electrical energy into mechanical vibration energy, which is amplified and transmitted to the cutter head 131 via the horn.

[0049] The measuring unit 140 is used to obtain electrical parameters of the ultrasonic scalpel energy output control system 100 during operation and transmit the electrical parameters of the ultrasonic scalpel energy output control system 100 during operation to the ultrasonic host 110. When the ultrasonic scalpel 130 includes a sensor 133, the measuring unit 140 is used to obtain a sensing signal from the sensor 133 and the electrical parameters of the ultrasonic scalpel energy output control system 100 during operation and transmit the sensing signal and the electrical parameters to the ultrasonic host 110. The sensing signal can be used to determine the blade state of the blade 131. The blade states involved in the embodiments of the present application include a first blade state and a second blade state, i.e., an open state and a closed state.

[0050] The measuring unit 140 includes a circuit.

[0051] In one embodiment, the measurement unit 140 is integrated into the ultrasound host 110 as a part / component of the ultrasound host 110. In another embodiment, the measurement unit 140 may also be integrated into the ultrasonic scalpel 130 as a part / component of the ultrasonic scalpel 130. Regardless of where the measurement unit 140 is integrated, its corresponding function remains unchanged, namely, obtaining the sensing signals from the sensor 133 and / or the electrical parameters of the ultrasonic scalpel energy output control system 100 during operation, and transmitting the sensing signals and / or electrical parameters to a component / element / object capable of processing the data, such as the controller 111.

[0052] The ultrasonic host 110 is connected to the transducer 120. The ultrasonic host 110 is used to provide electrical energy to the transducer 120, and obtain the sensing signal and / or electrical parameters when and / or after the ultrasonic scalpel 130 is excited, and control the energy delivered to the ultrasonic scalpel 130 according to the sensing signal and / or electrical parameters.

[0053] In one embodiment, by providing corresponding electrical energy, such as adjustable electrical energy, to the transducer 120, the corresponding electrical energy is used to drive the transducer 120 to provide corresponding kinetic energy, thereby controlling the energy delivered to the ultrasonic scalpel 130. Correspondingly, by providing a corresponding voltage (adjustable voltage), a corresponding current (adjustable current), or a corresponding power (adjustable power) to the transducer 120, the transducer 120 is controlled to provide kinetic energy corresponding to the corresponding voltage, current, or power, thereby controlling the energy delivered to the ultrasonic scalpel 130. That is, by providing currents of different voltages, currents, and powers to the transducer 120, the transducer 120 is controlled to provide corresponding kinetic energy, thereby controlling the energy delivered to the ultrasonic scalpel 130.

[0054] In one embodiment, the ultrasound host 110 provides fixed electrical energy to the transducer 120. The ultrasound host 110 controls the transducer 120 based on the sensing signal and / or electrical parameters, so that the transducer 120 processes the fixed electrical energy to adjust the kinetic energy provided by the transducer 120, thereby controlling the energy delivered to the ultrasonic scalpel 130. In this embodiment, the transducer 120 has a microchip, and this situation is not described in more detail in the embodiments of the present application.

[0055] The drive unit 112 of the ultrasound host 110 is used to provide electrical energy to the transducer 120 and drive the transducer 120. The controller 111 is used to determine the surgical procedure currently being performed by the ultrasonic scalpel 130 based on the open or closed state of the blade head 131 and electrical parameters when the ultrasonic scalpel 130 is performing a surgical procedure, and to control the energy delivered to the ultrasonic scalpel 130 based on the surgical procedure currently being performed by the ultrasonic scalpel 130.

[0056] The following further describes the working principle of the ultrasonic scalpel 130: The ultrasonic host 110 provides high-frequency electrical energy and transmits it to the transducer 120. The piezoelectric ceramic in the transducer 120 converts the electrical energy into mechanical vibration energy (hereinafter referred to as kinetic energy, including this mechanical vibration energy). The mechanical vibration energy is amplified by the horn and transmitted to the blade head 131. The blade head 131 generates vibrations at approximately 55.5kHz with an amplitude of approximately 50-100μm. The vibrating blade head 131 contacts the patient's tissue. The mechanical impact disrupts the hydrogen bonds of the tissue proteins. Simultaneously, due to the heat generated and the temperature rise, the tissue protein cells eventually denature and form a viscous coagulant, thereby achieving the purpose of cutting or coagulation. During the surgical procedure, medical personnel use the ultrasonic scalpel 130 to cut or coagulate tissue using various surgical procedures (also referred to as surgical operations). These surgical procedures include but are not limited to punching, back cutting, cutting, clamping cutting, or coagulation. The following will discuss some of these surgical operations.

[0057] In one embodiment, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to determine the state of the blade tip 131 based on the sensing signal, and to control the energy delivered to the ultrasonic scalpel 130 based on the blade tip state, such as controlling the transducer 120 to provide corresponding kinetic energy to control the energy output of the ultrasonic scalpel 130. For example, the controller 111 controls the drive unit 112 to provide corresponding electrical energy to the transducer 120 based on the blade tip state, so that the transducer 120 provides corresponding kinetic energy that matches the electrical energy, thereby controlling the energy delivered to the ultrasonic scalpel 130. In this embodiment, the sensing signal is only used to determine the blade tip state. The controller 111 controls the transducer 120 to provide corresponding kinetic energy based on the blade tip state, thereby adjusting the kinetic energy provided by the transducer 120 to adjust the energy output of the ultrasonic scalpel 130 and improve surgical quality.

[0058] The cutting head 131 has an open state and a closed state.

[0059] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to control the energy delivered to the ultrasonic scalpel 130 to be a fixed energy when the sensing signal indicates that the blade head is in the open state, such as controlling the transducer 120 to provide a fixed kinetic energy, thereby controlling the ultrasonic scalpel 130 to output a fixed energy. For example, when the controller 111 determines that the blade head is in the open state based on the sensing signal, it controls the drive unit 112 to provide a preset electrical energy to the transducer 120, where the preset electrical energy is determined by any one or more of a preset voltage, a preset current, or a preset power, so that the transducer 120 provides kinetic energy that matches the preset voltage, preset current, or preset power, thereby controlling the ultrasonic scalpel 130 to output a fixed energy.

[0060] Among them, the preset voltage is a fixed voltage, the preset current is a fixed current, and the preset power is a fixed power. The preset voltage, preset current or preset power is the voltage, current or power corresponding to the normal operation of the ultrasonic knife energy output control system 100, so that the transducer 120 outputs kinetic energy with a fixed amplitude (such as the preset amplitude), and will not be repeated below.

[0061] Among them, when the sensor 133 is a proximity sensor, a pressure sensor, a Hall sensor or a switch sensor, the above-mentioned determination of the cutting head state of the cutting head 131 based on the sensing signal includes: if there is a change in the sensing signal, the cutting head state of the cutting head 131 is determined to be an open state; if there is no change in the sensing signal, the cutting head state of the cutting head 131 is determined to be a closed state.

[0062] For example, when the sensor 133 is a proximity sensor, when the cutter head 131 is in a closed state, the proximity sensor will not be triggered. At this time, the proximity sensor has no sensing signal, or the sensing signal does not change. However, when the cutter head 131 is opened, the proximity sensor can detect it and generate a sensing signal. Therefore, there is a change in the sensing signal.

[0063] For example, when the sensor 133 is a switch sensor, when a pressure signal is detected on the pressure sensor, the blade head 131 of the ultrasonic knife 130 is opened according to the pressure signal. When the blade head of the ultrasonic knife 130 is in a closed state, there is no need to trigger the switch sensor.

[0064] In the following, please refer to the description of this section for determining the cutter head state according to the sensing signal, which will not be repeated in the following text.

[0065] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to control the energy delivered to the ultrasonic knife 120 to be fixed energy when the sensing signal indicates that the blade head state is in a closed state, for example, controlling the transducer 120 to provide fixed kinetic energy to control the ultrasonic knife 130 to output fixed energy.

[0066] In one embodiment, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to determine the blade state of the blade 131 based on the sensing signal, determine the surgical procedure currently being performed by the ultrasonic scalpel 130 based on the blade state, or determine the surgical procedure currently being performed by the ultrasonic scalpel 130 based on the blade state and electrical parameters, and control the energy delivered to the ultrasonic scalpel 130 based on the surgical procedure currently being performed by the ultrasonic scalpel 130. In this embodiment, the sensing signal is only used to determine the blade state. After the blade state is determined, the surgical procedure is determined. Finally, the energy delivered to the ultrasonic scalpel 130 is controlled based on the surgical procedure. This allows the ultrasonic scalpel 130 to output energy corresponding to the surgical procedure under different blade states, thereby improving surgical quality.

[0067] The surgical operation currently being performed by the ultrasonic scalpel 130 is determined based on the blade head state. If the blade head state is open, the surgical operation is determined to be a first operation, which includes perforation or back cutting; and if the blade head state is closed, the surgical operation is determined to be a second operation, which includes clamping and cutting, shearing, or coagulation. In this embodiment, the surgical operation is determined based solely on the blade head state.

[0068] The surgical operation currently being performed by the ultrasonic scalpel 130 is determined based on the blade state and electrical parameters. The following examples are provided: If the blade state is open and the electrical parameters have changed, the surgical operation is determined to be a first operation, which includes perforation or back cutting; If the blade state is closed and the electrical parameters have changed, the surgical operation is determined to be a second operation, which includes clamping and cutting, cropping, or coagulation. In this embodiment, the surgical operation is determined based on both the blade state and the electrical parameters. A change in the electrical parameters indicates that a surgical operation is currently being performed, excluding situations where no surgical operation is currently being performed or where another surgical operation is currently being performed, thereby improving the accuracy of determining the surgical operation.

[0069] The surgical operation currently being performed by the ultrasonic scalpel 130 is determined based on the blade state and electrical parameters, including: if the blade state is in an open state and the electrical parameters conform to the electrical parameter curve corresponding to the first operation, the surgical operation is determined to be the first operation, which is punching or back cutting; if the blade state is in a closed state and the electrical parameters conform to the electrical parameter curve corresponding to the second operation, the surgical operation is determined to be the second operation, which includes clamping cutting, cropping, or coagulation. In this embodiment, the surgical operation is determined based on the blade state and electrical parameters together, wherein not only does the electrical parameters need to change, that is, the ultrasonic host energy is being output, but the electrical parameters also need to conform to the electrical parameter curve of the corresponding operation mode in order to determine the corresponding surgical operation, further improving the accuracy of determining the surgical operation.

[0070] It should be pointed out in particular that, in this embodiment, "electrical parameter changes", "electrical parameters have changed", etc. are intended to indicate that the energy is in an excited state. Unless otherwise specified, the "electrical parameter changes" and "electrical parameters have changed" in the following embodiments describe the state in which the ultrasound host is outputting energy.

[0071] The electrical parameters include any one or more of power, voltage, current, frequency, and impedance.

[0072] Among them, not only the corresponding surgical operation can be determined according to the electrical parameters, but also the surgical operation status of the surgical operation can be determined according to the electrical parameters (to be described below), and the tissue status corresponding to the surgical operation can also be determined according to the electrical parameters (to be described below).

[0073] FIG3 is a schematic diagram of electrical parameters during tissue clamping and cutting according to an embodiment of the present application. During tissue cutting using an ultrasonic scalpel 130, the electrical parameters of the ultrasonic scalpel energy output control system 100 vary depending on the surgical procedure, and the electrical parameters change accordingly based on the tissue cutting state. Therefore, the tissue cutting state (also referred to as the tissue cutting state) can be further identified based on the changes in the corresponding electrical parameters. The corresponding tissue cutting state corresponds to the following terms: "about to be cut (tissue about to be severed), "already cut (tissue already severed)," etc. Furthermore, the surgical operation state can be further identified based on the changes in the corresponding electrical parameters, such as the following terms: "about to be cut" and "already cut (tissue already severed).

[0074] In Figure 3, the top electrical parameter curve is the impedance curve, the middle electrical parameter curve is the voltage curve, and the bottom electrical parameter curve is the power curve. Taking the power curve as an example, the period from 0 seconds to the first peak represents the excitation phase of the ultrasonic scalpel 130. At this time, the energy output of the ultrasonic scalpel energy output control system 100 rapidly increases to a maximum value, corresponding to the first peak of the power curve, while the impedance decreases. When it starts to decline from the maximum value, it means that the ultrasonic scalpel energy output control system 100 starts clamping and cutting. In the initial stage of clamping and cutting, the energy output of the ultrasonic scalpel energy output control system 100 gradually increases to the desired energy, and the ultrasonic scalpel energy output control system 100 also gradually enters the resonant state. At this time, the voltage and power of the ultrasonic scalpel energy output control system 100 gradually increase, and the impedance gradually decreases as the system enters the resonant state; in the clamping and cutting process, as the temperature of the blade 131 increases, the moisture in the tissue evaporates, and the load of the blade 131 gradually increases. At this time, the impedance, voltage and power of the ultrasonic scalpel energy output control system 100 all increase; at the end of the clamping and cutting process, as the cutting tissue decreases, the blade load gradually decreases. At this time, the impedance, voltage and power of the ultrasonic scalpel energy output control system 100 all decrease; when the ultrasonic scalpel 130 leaves the tissue, the impedance, voltage and power of the ultrasonic scalpel energy output control system 100 all decrease rapidly.

[0075] Figure 4 is a schematic diagram of power and blade status during tissue clamping and cutting provided by an embodiment of the present application. The upper figure is a schematic diagram of power during tissue clamping and cutting, with time plotted on the horizontal axis and power plotted on the vertical axis. The lower figure is a schematic diagram of blade status, with time plotted on the horizontal axis and a vertical axis of 1 indicating a closed blade or jaw state, and 0 indicating an open blade or jaw state. As can be seen from the power diagram, the change from the power starting to the first peak means that it is in the excitation stage of the ultrasonic scalpel 130. At this time, the energy output of the ultrasonic scalpel energy output control system 100 rapidly increases to a maximum value. When it starts to decrease from the maximum value, it means that the ultrasonic scalpel energy output control system 100 starts clamping and cutting. The ultrasonic scalpel energy output control system 100 will gradually enter a resonant state. During the clamping and cutting process, as the temperature of the blade head 131 increases, the moisture in the tissue evaporates, and the load of the blade head 131 of the ultrasonic scalpel 130 gradually increases. At this time, the power of the ultrasonic scalpel energy output control system 100 is in an increasing state, such as between about 1 second and 1.5 seconds; at the end of the clamping and cutting, as the cutting tissue decreases, the load of the blade head 131 gradually decreases. At this time, the power of the ultrasonic scalpel energy output control system 100 is in a decreasing state, such as between about 1.5 seconds and 2 seconds, which is a state where the cutting is about to be completed. At about 2.5 seconds, the excitation is stopped.

[0076] FIG5 is a schematic diagram of the power and blade state during multiple back-cutting of tissues provided by an embodiment of the present application. FIG6 is a schematic diagram of the power and blade state during perforating tissues provided by an embodiment of the present application. According to the electrical parameter schematic diagrams shown in FIG5 and FIG6, the corresponding surgical operation currently being performed by the ultrasonic scalpel 130 can be identified. Furthermore, the surgical operation state, such as the operation progress state and the operation end state described later, can be determined based on the electrical parameters. At the same time, the tissue state can be further identified based on the changes in the corresponding electrical parameters, such as the operation being perforated or back-cutting, the perforation or back-cutting being completed, etc. described later.

[0077] As shown in Figure 5, the upper figure is a power diagram for multiple back-cutting of tissues, and the zero in the lower figure indicates that the blade is in the open state. As can be seen in the power diagram, the change from the power representation to the first small peak means that the ultrasonic scalpel energy output control system 100 is in the excitation phase, and the power change from the power drop to the first extremely low point (such as about 3 seconds) is the power change of one back-cutting of tissues. Among them, about 2 seconds is the ultrasonic scalpel 130 gradually leaving the tissue, and about 3 seconds indicates leaving the tissue. From this extremely low point to the next extremely low point is the power change of another back-cutting of tissues (such as about 3 seconds to about 5.7 seconds), and so on.

[0078] As shown in Figure 6, the upper figure is a schematic diagram of tissue perforation power. The zero in the lower figure indicates that the blade is in the open state. In the power diagram, it can be seen that the change from the power representation to the first small peak indicates that the ultrasonic scalpel energy output control system 100 is in the excitation stage, and then begins to perforate the tissue. At about 2.5 seconds, there is a transient rapid rise line, indicating that the perforation process is complete. Then, starting from the power maximum value, it means that the ultrasonic scalpel 130 is gradually leaving the tissue.

[0079] As shown in Figures 3 to 6, different surgical procedures correspond to different electrical parameter curves. Different electrical parameters in the same surgical procedure also correspond to different electrical parameter curves. The surgical procedure currently being performed by the ultrasonic scalpel 130 is determined based on the blade state and electrical parameters. The figures only list some electrical parameter curves, such as the power curve. Since power, voltage, impedance, and frequency can all be converted to each other using physical formulas, other electrical parameter curves, such as frequency curves, voltage curves, and impedance curves, can also be derived.

[0080] The above describes how to determine the surgical operation currently being performed by the ultrasonic scalpel 130 based on the blade state, and how to determine the surgical operation currently being performed by the ultrasonic scalpel 130 based on the blade state and electrical parameters. For details on determining the surgical operation currently being performed by the ultrasonic scalpel 130 based on the blade state and electrical parameters, please refer to the description in that section and will not be repeated here.

[0081] After determining the state of the blade tip and the surgical procedure currently being performed by the ultrasonic scalpel 130, the energy delivered to the ultrasonic scalpel 130 is controlled according to the surgical procedure. For example, the controller 111 controls the drive unit 112 to provide corresponding electrical energy to the transducer 120 according to the surgical procedure currently being performed by the ultrasonic scalpel 130, so that the transducer 120 provides corresponding kinetic energy that matches the electrical energy, thereby controlling the energy delivered to the ultrasonic scalpel 130.

[0082] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to control the energy delivered to the ultrasonic scalpel 130 to be a fixed energy when the sensing signal indicates that the blade state is an open state, and the open state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is a first operation, wherein the first operation includes perforation or back cutting. For example, the controller 111 controls the drive unit 112 to provide a preset electrical energy to the transducer 120, where the preset electrical energy is determined by any one or more of a preset voltage, a preset current, or a preset power, so that the transducer 120 provides kinetic energy that matches the preset voltage, preset current, or preset power, thereby controlling the energy delivered to the ultrasonic scalpel 130 to be a fixed energy.

[0083] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to control the energy delivered to the ultrasonic scalpel 130 to be fixed energy when the sensing signal indicates that the blade state is a closed state, and the closed state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is a second operation, wherein the second operation includes clamping cutting, trimming or coagulation.

[0084] In one embodiment, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to determine the blade state of the blade 131 based on the sensing signal, determine the surgical operation based on the blade state, or determine the surgical operation based on the blade state and electrical parameters, determine the surgical operation status of the surgical operation based on the electrical parameters, and control the energy delivered to the ultrasonic scalpel 130 based on the blade state, the surgical operation, and the surgical operation status. In this embodiment, the sensing signal is used only to determine the blade state. After determining the surgical operation and the surgical operation status, the energy delivered to the ultrasonic scalpel 130 is controlled based on the blade state, the surgical operation, and the surgical operation status. This allows the ultrasonic scalpel 130 to output energy corresponding to different surgical operation states in different blade states, thereby improving surgical quality.

[0085] The surgical operation status includes an inoperative state, an ongoing state, an operation about to end state, and an operation end state. The inoperative state means that although the ultrasonic scalpel 130 has been activated, the ultrasonic scalpel 130 is not performing any surgical operation; the ongoing state means that the ultrasonic scalpel is performing a surgical operation, such as punching or back cutting, the ongoing state means punching or back cutting is in progress; the operation about to end state means that a surgical operation currently being performed by the ultrasonic scalpel 130 is about to end, such as clamping and cutting, the operation about to end state means that clamping and cutting are about to be completed; the operation end state means that the ultrasonic scalpel has completed a surgical operation, such as punching or back cutting, the operation end state means that punching or back cutting is complete.

[0086] Among them, when the surgical operation is determined to be the first operation, the above-mentioned determination of the surgical operation status of the surgical operation based on the electrical parameters includes: if the electrical parameters are reduced to the corresponding first preset parameter threshold, the surgical operation status of the surgical operation is determined to be the operation end state; if the electrical parameters have changed, but the electrical parameters have not been reduced to the corresponding first preset parameter threshold, the surgical operation status of the surgical operation is determined to be the operation in progress state.

[0087] Among them, if the electrical parameter is power, the first preset parameter threshold corresponds to the first preset power threshold; if the electrical parameter is voltage or current, the first preset parameter threshold corresponds to the first preset voltage threshold or the first preset current threshold; if the electrical parameter is frequency, the first preset parameter threshold corresponds to the first preset frequency threshold; if the electrical parameter is impedance, the first preset parameter threshold corresponds to the first preset impedance threshold, wherein the first preset power threshold, the first preset voltage threshold, the first preset current threshold, the first preset frequency threshold or the first preset impedance threshold are all set in advance through experiments or other methods.

[0088] For example, the first preset parameter threshold is less than the minimum parameter value corresponding to the surgical operation state of the ultrasonic scalpel energy output control system 100 when the operation is in progress. For example, the first preset power threshold is less than the minimum power value corresponding to the ultrasonic scalpel energy output control system 100 when drilling or back-cutting is in progress, or the first preset voltage threshold is less than the minimum voltage value corresponding to the ultrasonic scalpel energy output control system 100 when drilling or back-cutting is in progress. If the electrical parameter decreases to the corresponding first preset parameter threshold, it means that the surgical operation is completed, that is, the surgical operation state of the surgical operation is in the operation-completed state. Otherwise, if the electrical parameter changes but the electrical parameter does not decrease to the corresponding first preset parameter threshold, it means that the surgical operation of drilling or back-cutting is in progress.

[0089] When the sensing signal indicates that the blade tip is in a closed state and the blade tip state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is a second operation, determining the surgical operation state of the surgical operation based on the electrical parameters includes: determining that the surgical operation state of the second operation is about to end when a minimum value and a maximum value of the electrical parameter are identified, and when the electrical parameter decreases by more than a corresponding threshold value. For example, when the electrical parameter changes from a minimum value to a maximum value and then decreases from the maximum value, and the decrease exceeds a second preset threshold value, the surgical operation state of the second operation is determined to be about to end; otherwise, the surgical operation state of the second operation is determined to be in progress. The electrical parameter may be power, for example. For example, when the blade tip is in a closed state and clamping and cutting is being performed, if the electrical parameter changes from a minimum value to a maximum value and then decreases from the maximum value, and the decrease exceeds a second preset threshold value, the clamping and cutting operation is determined to be about to end, indicating that tissue is about to be severed. Otherwise, it indicates that clamping and cutting are still in progress and the tissue is not yet severed.

[0090] Among them, if the electrical parameter is power, the second preset amplitude threshold corresponds to the second preset power threshold; if the electrical parameter is voltage or current, the second preset amplitude threshold corresponds to the second preset voltage or current threshold; if the electrical parameter is frequency, the second preset amplitude threshold corresponds to the second preset frequency threshold; if the electrical parameter is impedance, the second preset amplitude threshold corresponds to the second preset impedance threshold, wherein the second preset power threshold, the second preset voltage or current threshold, the second preset frequency threshold or the second preset impedance threshold are all set in advance through experiments or other methods.

[0091] For the following description of determining the surgical operation status according to the electrical parameters, please refer to the description in this section, which will not be repeated in the following text.

[0092] In one embodiment, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to determine the surgical procedure currently being performed by the ultrasonic scalpel 130 based on the sensing signal and the electrical parameters, or to determine the surgical procedure currently being performed by the ultrasonic scalpel 130 based on the sensing signal and the electrical parameters, determine the surgical operation status of the surgical procedure based on the electrical parameters, and control the energy delivered to the ultrasonic scalpel 130 based on the surgical operation and the surgical operation status. In this embodiment, the surgical procedure currently being performed by the ultrasonic scalpel 130 is determined based on both the sensing signal and the electrical parameters, thereby improving the accuracy of determining the surgical procedure, improving the accuracy of ultrasonic scalpel energy control, and improving surgical efficiency.

[0093] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to, when the sensing signal indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is a first operation, or the sensing signal and the electrical parameter indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, and the surgical operation state of the surgical operation is determined to be an inoperative state according to the electrical parameter, control the energy delivered to the ultrasonic scalpel 130 to be a fixed energy, and the first operation includes punching or back cutting; or

[0094] When the sensing signal indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, the sensing signal and the electrical parameter indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, and the surgical operation state of the first operation is determined to be the operation end state according to the electrical parameter, controlling the energy delivered to the ultrasonic scalpel 130 to be reduced, or controlling the energy delivery to the ultrasonic scalpel 130 to be stopped;

[0095] Alternatively, when the sensing signal indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, the sensing signal and the electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, and the electrical parameters indicate that the surgical operation state of the first operation changes from the operation in progress state to the operation end state, the energy delivered to the ultrasonic scalpel 130 is controlled to be reduced, or the energy delivery to the ultrasonic scalpel 130 is controlled to be stopped.

[0096] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to control the reduction of energy delivered to the ultrasonic scalpel 130, or control the cessation of energy delivery to the ultrasonic scalpel 130, when the sensing signal indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is a second operation, the sensing signal and the electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the surgical operation state of the second operation is determined according to the electrical parameters to be a state in which the operation is about to end or a state in which the operation is ended. The second operation includes clamping cutting, trimming or coagulation.

[0097] In one embodiment, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to determine whether the blade head 131 is in an open or closed state based on the sensing signal, determine the surgical procedure currently being performed by the ultrasonic scalpel 130 based on the blade head state, or determine the surgical procedure currently being performed by the ultrasonic scalpel 130 based on the blade head state and electrical parameters, determine the surgical operation state of the surgical procedure based on the electrical parameters, and control the energy delivered to the ultrasonic scalpel 130 based on the blade head state, the surgical operation, and the surgical operation state. In this embodiment, the sensing signal is used only to determine the blade head state. After determining the surgical operation and the surgical operation state, the energy delivered to the ultrasonic scalpel 130 is controlled based on the blade head state, the surgical operation, and the surgical operation state. This allows the ultrasonic scalpel 130 to control different surgical operations under different blade head states, with corresponding energy output in different surgical operation states corresponding to different surgical operations, thereby improving surgical quality.

[0098] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to control the energy delivered to the ultrasonic scalpel 130 to be fixed energy when the sensing signal indicates that the blade state is in the open state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, and the electrical parameters (such as the electrical parameter change) indicate that the surgical operation state of the first operation is in the non-operation state, wherein the first operation includes perforation or back-cutting. That is, when the blade state is in the open state and perforation or back-cutting is not being performed, it means that the corresponding perforation or back-cutting surgical operation is being accurately performed. At this time, a fixed energy output is used to facilitate the corresponding surgical operation.

[0099] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to control the reduction of energy delivered to the ultrasonic scalpel 130, such as controlling the transducer 120 to reduce kinetic energy, to control the ultrasonic scalpel 130 to reduce energy output, or control the stop of energy delivery to the ultrasonic scalpel 130, such as controlling the transducer 120 to stop outputting kinetic energy, to control the ultrasonic scalpel 130 to stop energy output, when the sensing signal indicates that the blade state is an open state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is a first operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is a first operation, and the electrical parameters (such as the electrical parameter change) indicate that the surgical operation state of the first operation is an operation end state. In this embodiment, when the blade head is in an open state, and the surgical operation is punching or back-cutting, and the electrical parameters (such as the change in electrical parameters) represent the end of punching or back-cutting, the energy delivered to the ultrasonic scalpel 130 is controlled to be reduced, or the energy delivery to the ultrasonic scalpel 130 is controlled to be stopped, so as to avoid the possibility of accidentally injuring other tissues when retrieving the blade head 131 of the ultrasonic scalpel 130 from the tissue, thereby improving the quality of the surgery.

[0100] The transducer 120 is controlled to reduce kinetic energy, and the controller 111 is used to provide reduced electrical energy, such as the first electrical energy, to the transducer 120. The reduced first electrical energy drives the transducer 120 to provide kinetic energy that matches the first electrical energy. In this way, the transducer 120 reduces kinetic energy to reduce the energy output of the ultrasonic scalpel 130. The first electrical energy is lower than the preset electrical energy, and the first electrical energy is determined by any one or more of the first voltage, the first current, or the first power. The first voltage is lower than the preset voltage, the first current is lower than the preset current, and the first power is lower than the preset power. The transducer 120 is controlled to stop providing kinetic energy, and the controller 111 is notified to stop the driving unit 112 from outputting electrical energy to the transducer 120, or the electrical energy provided to the transducer 120 is set to zero.

[0101] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to control the reduction of energy delivered to the ultrasonic scalpel 130 or the cessation of energy delivery to the ultrasonic scalpel 130 when the sensing signal indicates that the blade state is in the open state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is a first operation, or when the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, and the electrical parameters indicate that the surgical operation state of the first operation changes from an operation-in-progress state to an operation-completed state, wherein the first operation includes perforation or back-cutting. This embodiment differs from the previous embodiment in that it defines that when the surgical operation state of the first operation indicated by the electrical parameters (e.g., the electrical parameter change) changes from an operation-in-progress state to an operation-completed state, it means that the surgical operation corresponding to the first operation has changed from being performed to being completed. This allows for more accurate determination that the surgical operation corresponding to the first operation, such as perforation or back-cutting, has ended. At this point, the energy output of the ultrasonic scalpel 130 is reduced or stopped to improve surgical quality.

[0102] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to control the reduction of energy delivered to the ultrasonic scalpel 130 or the cessation of energy delivery to the ultrasonic scalpel 130 when the sensing signal indicates that the blade state is closed, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the electrical parameters (such as the electrical parameter change) indicate that the surgical operation state of the second operation is about to end, wherein the second operation includes clamping cutting, cutting, or coagulation. For example, when the blade state is closed, during clamping cutting, if the clamping cutting is about to end, the energy delivered to the ultrasonic scalpel 130 is controlled to be reduced, or the energy delivery to the ultrasonic scalpel 130 is controlled to be stopped. For the implementation method of controlling the transducer 120 to reduce kinetic energy or the method of controlling the transducer 120 to stop providing kinetic energy, please refer to the corresponding description above. In this embodiment, when the blade is in a closed state and clamping and cutting is in progress, the energy delivered to the ultrasonic scalpel 130 is reduced or the energy delivery to the ultrasonic scalpel 130 is stopped to avoid accidental injury to other tissues and improve the quality of the operation.

[0103] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to control the reduction of energy delivered to the ultrasonic scalpel 130, or control the cessation of energy delivery to the ultrasonic scalpel 130, when the sensing signal indicates that the blade state is a closed state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the electrical parameters (such as the electrical parameter change) indicate that the surgical operation state of the second operation is the operation end state, wherein the second operation includes clamping cutting, cutting or coagulation to improve the quality of the operation.

[0104] In one embodiment, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to determine whether the blade head 131 is in an open or closed state based on the sensing signal, determine the surgical procedure currently being performed by the ultrasonic scalpel 130 based on the blade head state, or determine the surgical procedure currently being performed by the ultrasonic scalpel 130 based on the blade head state and electrical parameters, determine the tissue state corresponding to the surgical procedure based on the electrical parameters, and control the energy delivered to the ultrasonic scalpel 130 based on the blade head state, the surgical procedure, and the tissue state. In this embodiment, the energy output of the ultrasonic scalpel 130 is controlled based on the blade head state, the surgical procedure, and the tissue state. The tissue state corresponding to the surgical procedure is determined based on the electrical parameters.

[0105] Among them, for the first operation such as punching or back cutting, the tissue status includes punching or back cutting in progress, punching or back cutting completed, not punching or back cutting in progress, etc. For the second operation such as clamping cutting, the tissue status includes about to be cut (tissue is about to be severed), already cut (tissue has been severed), not cut, tissue not severed, etc.

[0106] Among them, when the sensing signal indicates that the blade state is in an open state, and the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic blade 130 is a first operation, the tissue state corresponding to the first operation is determined based on the electrical parameters, including: if the electrical parameter is reduced to the corresponding first preset parameter threshold, determining that the tissue state corresponding to the first operation is a punching or back-cutting end state; otherwise, if the electrical parameter changes (the ultrasonic host has energy output), determining that the tissue state corresponding to the first operation is in the process of punching or back-cutting.

[0107] Among them, when the sensing signal indicates that the blade state is a closed state, and the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic blade 130 is a second operation, the tissue state corresponding to the second operation is determined according to the electrical parameters, including: when the electrical parameter changes from a minimum value to a maximum value, and then starts to decrease from the maximum value, and the decrease amplitude value exceeds the corresponding second preset amplitude threshold, then the tissue state corresponding to the second operation is determined to be the state where the operation is about to be cut or the state where the cutting is completed; otherwise, the tissue state corresponding to the second operation is determined to be the state in which the cutting is in progress.

[0108] In some usage scenarios, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further used to control the energy delivered to the ultrasonic scalpel 130 to be fixed energy when the sensing signal indicates that the state of the blade is in the open state, the state of the blade indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, or the state of the blade and the electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, and the electrical parameters indicate that the tissue state corresponding to the first operation is not perforating or back-cutting; or,

[0109] When the sensing signal indicates that the blade state is in the open state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, and the electrical parameters indicate that the tissue state corresponding to the first operation is performing perforation or back cutting, the energy delivered to the ultrasonic scalpel 130 is controlled to be a fixed energy; or

[0110] When the sensing signal indicates that the state of the blade head is open, the state of the blade head indicates that the surgical operation currently being performed by the ultrasonic blade 130 is the first operation, or the state of the blade head and the electrical parameters indicate that the surgical operation currently being performed by the ultrasonic blade 130 is the first operation, and the electrical parameters indicate that the tissue state corresponding to the first operation is the end of punching or back cutting, the control is to reduce the energy delivered to the ultrasonic blade 130, or stop delivering energy to the ultrasonic blade 130.

[0111] In some usage scenarios, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, controls the energy delivered to the ultrasonic scalpel 130 to be fixed energy when the sensing signal indicates that the blade state is a closed state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the electrical parameters (such as the electrical parameter change) indicate that the tissue state corresponding to the surgical operation is not cutting; or

[0112] When the sensing signal indicates that the state of the blade head is closed, the state of the blade head indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, or the state of the blade head and the electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the electrical parameters (such as the change in the electrical parameters) indicate that the tissue state corresponding to the surgical operation is about to be cut, control the reduction of energy delivered to the ultrasonic scalpel 130, or stop delivering energy to the ultrasonic scalpel 130; or

[0113] When the sensing signal indicates that the blade state is a closed state, the blade state indicates that the surgical operation currently being performed by the ultrasonic blade 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic blade 130 is the second operation, and the electrical parameters (such as the change in electrical parameters) indicate that the tissue state corresponding to the surgical operation has been cut, the energy output delivered to the ultrasonic blade 130 is reduced, or the energy delivery to the ultrasonic blade 130 is stopped.

[0114] In one embodiment, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to obtain a preset energy control flag, wherein the preset energy control flag may be determined by a preset gear position or a preset energy operation state.

[0115] For example, in the ultrasound host 110 or in the ultrasound knife 130, different gears are set, and the gears can be represented by gear keys or gear buttons or gear switches. Among them, the different gears include gear one, gear two and gear three, gear one supports / allows energy reduction, gear two does not support / prohibits energy reduction, gear three supports / allows energy output to be stopped, and gear four does not support / prohibits energy output to be stopped. Among them, the values ​​of gears one to four are represented by energy control flags. If gear one is pre-selected, set or turned on, the energy control flag is set to 1, indicating that energy reduction is supported. If gear two is pre-selected, set or turned on, the energy control flag is set to 2, indicating that energy reduction is prohibited / energy reduction is not supported. If gear three is pre-selected, set or turned on, the energy control flag is set to 3, indicating that energy output is supported / allowed to be stopped. If gear four is pre-selected, set or turned on, the energy control flag is set to 4, indicating that energy output is prohibited / not supported to be stopped. Or if it is not pre-selected or pre-set, the default energy control flag is set to 2. Thus, the energy output status during the surgical operation is divided into three situations: fixed energy output, reduced energy output, and stopped energy output.

[0116] In one case, only gear positions 1 and 2 may be set, indicating either supporting / allowing energy reduction or not supporting / allowing energy reduction. Accordingly, the energy output state during the surgical operation is divided into two cases: fixed energy output and reduced energy output. In another case, only gear positions 3 and 4 may be set, indicating either supporting / allowing energy output cessation or supporting / allowing energy output cessation. Accordingly, the energy output state during the surgical operation is divided into two cases: fixed energy output and stopped energy output.

[0117] For example, in the display device of the ultrasound host (if any) or on the ultrasound host 110, such as on the outer shell of the ultrasound host 110 or on the ultrasonic knife 130, a button or key indicating whether energy reduction is supported and a button or key indicating whether energy output is stopped are displayed / set. If the button or key supporting energy reduction is triggered in advance, the energy operation state is set to 1, indicating that energy reduction is supported / allowed; otherwise, the energy operation state is set to 2, indicating that energy reduction is prohibited / energy reduction is not supported; if the button or key for stopping energy output is triggered in advance, the energy operation state is set to 3, indicating that stopping energy output is supported / allowed; otherwise, the energy operation state is set to 4, indicating that stopping energy output is prohibited / not supported.

[0118] Among them, in one embodiment, only the button or key that supports reducing energy can be triggered, and correspondingly, the energy output state during the surgical operation is divided into two situations: fixed energy output and reduced energy output; in one embodiment, only the button or key that stops energy output can be triggered, and correspondingly, the energy output state during the surgical operation is divided into two situations: fixed energy output and stopped energy output.

[0119] Correspondingly, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to determine whether the blade head 131 is in an open or closed state based on the sensing signal, determine the surgical operation currently being performed by the ultrasonic scalpel 130 based on the blade head state, or determine the surgical operation currently being performed by the ultrasonic scalpel 130 based on the blade head state and electrical parameters, determine the surgical operation state of the surgical operation based on the electrical parameters, and control the energy delivered to the ultrasonic scalpel 130 based on the blade head state, the surgical operation, the surgical operation state, and the energy control flag. In this embodiment, the transducer 120 is further controlled to provide corresponding kinetic energy based on the energy control flag, thereby flexibly reducing or stopping the energy output of the ultrasonic scalpel 130.

[0120] In some usage scenarios, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to control the reduction of energy delivered to the ultrasonic scalpel 130 when the sensing signal indicates that the blade state is in the open state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, the electrical parameters indicate that the surgical operation state of the first operation is in the operation end state, or the electrical parameters indicate that the surgical operation state of the first operation is changed from the operation in progress state to the operation end state, and the energy control flag indicates that energy reduction is supported;

[0121] Alternatively, when the sensing signal indicates that the blade state is in the open state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, the electrical parameters indicate that the surgical operation state of the first operation is in the operation end state, or the electrical parameters indicate that the surgical operation state of the first operation has changed from the operation in progress state to the operation end state, and the energy control flag indicates that energy reduction is supported, the control stops delivering energy to the ultrasonic scalpel 130;

[0122] Alternatively, when the sensing signal indicates that the blade state is in the open state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, the electrical parameters indicate that the surgical operation state of the first operation is in the operation end state, or the electrical parameters indicate that the surgical operation state of the first operation has changed from the operation in progress state to the operation end state, and the energy control flag indicates that stopping energy output is supported, control stops delivering energy to the ultrasonic scalpel 130;

[0123] Or when the sensing signal indicates that the blade state is in the open state, the blade state indicates that the surgical operation currently being performed by the ultrasonic blade 130 is the first operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic blade 130 is the first operation, the electrical parameters indicate that the surgical operation state of the first operation is the operation end state, or the electrical parameters indicate that the surgical operation state of the first operation is changed from the operation in progress state to the operation end state, and the energy control mark indicates that energy reduction is not supported / prohibited, the energy delivered to the ultrasonic blade 130 is controlled to be fixed energy.

[0124] For example, when the blade head is in the open state, the perforation or back resection surgical procedure has concluded, and energy reduction is supported, the controller 111 provides reduced electrical energy, such as a second electrical energy, to the transducer 120. This reduced second electrical energy drives the transducer 120 to provide kinetic energy that matches the second electrical energy, thereby controlling the reduction of the energy delivered to the ultrasonic scalpel 130. The second electrical energy is lower than a preset electrical energy, and the second electrical energy is determined by any one or more of a second voltage, a second current, or a second power. The second voltage is lower than the preset voltage, the second current is lower than the preset current, and the second power is lower than the preset power. The second electrical energy may be the same as or different from the first electrical energy. When the blade head is in the open state, the perforation or back resection surgical procedure has concluded, and energy reduction is not supported / prohibited, the controller 111 provides the preset electrical energy to the transducer 120 to drive the transducer 120 to provide kinetic energy that matches the preset electrical energy, thereby controlling the energy delivered to the ultrasonic scalpel 130 to be a fixed energy.

[0125] In some usage scenarios, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is further configured to control the reduction of energy delivered to the ultrasonic scalpel 130 when the sensing signal indicates that the blade state is in the closed state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, the electrical parameters indicate that the surgical operation state of the second operation is in the operation about to end state or the operation end state, and the energy control flag indicates that energy reduction is supported;

[0126] Alternatively, when the sensing signal indicates that the blade state is in the closed state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, the electrical parameters indicate that the surgical operation state of the second operation is in the operation about to end state or the operation end state, and the energy control flag indicates that energy reduction is supported, the control stops delivering energy to the ultrasonic scalpel 130;

[0127] Alternatively, when the sensing signal indicates that the blade state is in the closed state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, the electrical parameters indicate that the surgical operation state of the second operation is in the operation about to end state or the operation end state, and the energy control flag indicates that energy stopping is supported, control stops delivering energy to the ultrasonic scalpel 130;

[0128] Or when the sensing signal indicates that the blade state is a closed state, the blade state indicates that the surgical operation currently being performed by the ultrasonic blade 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic blade 130 is the second operation, the electrical parameters indicate that the surgical operation state of the second operation is a state about to end or a state where the operation is ended, and the energy control identifier indicates that energy reduction is not supported / prohibited, the energy delivered to the ultrasonic blade 130 is controlled to be fixed energy.

[0129] For example, when the blade is in the closed state, the clamping and cutting surgical operation has ended or is about to end, and energy reduction is supported, the controller 111 provides reduced electrical energy, such as a third electrical energy, to the transducer 120. This reduced third electrical energy drives the transducer 120 to provide kinetic energy that matches the third electrical energy, thereby controlling the reduction of the energy delivered to the ultrasonic scalpel 130. Alternatively, the controller 111 provides zero electrical energy to the transducer, or does not provide electrical energy to the transducer 120, to control the transducer 120 to stop providing electrical energy, thereby controlling the cessation of energy delivery to the ultrasonic scalpel 130. The third electrical energy is lower than a preset electrical energy and is determined by any one or more of a third voltage, a third current, or a third power. The third voltage is lower than the preset voltage, the third current is lower than the preset current, and the third power is lower than the preset power. The third electrical energy may be the same as or different from the second electrical energy and the first electrical energy. When the blade is in the closed state, the clamping and cutting surgical operation has ended or is about to end, and energy reduction is not supported, the controller 111 provides preset electrical energy to the transducer 120 to drive the transducer 120 to provide kinetic energy matching the preset electrical energy, that is, to control the energy delivered to the ultrasonic knife 130 to be fixed energy.

[0130] In one embodiment, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to obtain a pre-set energy control identifier; the ultrasound host 110 is also used to determine the surgical operation currently being performed by the ultrasonic scalpel 130 based on the sensing signal and the electrical parameters, determine the surgical operation status of the surgical operation based on the electrical parameters, and control the energy delivered to the ultrasonic scalpel 130 based on the surgical operation, the surgical operation status and the energy control identifier.

[0131] In one usage scenario, the ultrasound host 110 is also used to, when it is determined based on the sensing signal and the electrical parameters that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, and it is determined based on the electrical parameters that the surgical operation status of the first operation is the operation end state, and the energy control identifier indicates that energy reduction is supported, control the reduction of energy delivered to the ultrasonic scalpel 130, or control the stop of energy delivery to the ultrasonic scalpel 130, the first operation includes punching or back cutting; when it is determined based on the sensing signal and the electrical parameters that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, and it is determined based on the electrical parameters that the surgical operation status of the first operation is the operation end state, and the energy control identifier indicates that energy reduction is not supported / energy stopping is not supported, control the energy delivered to the ultrasonic scalpel 130 to be fixed energy.

[0132] In one usage scenario, the ultrasound host 110 is also used to, when it is determined based on the sensing signal and the electrical parameters that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the surgical operation status of the second operation is determined based on the electrical parameters to be the operation about to end or the operation end, and the energy control identifier indicates that energy reduction is supported, control the reduction of energy delivered to the ultrasonic scalpel 130, or control the stop of energy delivery to the ultrasonic scalpel 130, the second operation includes clamping cutting, trimming or coagulation; when it is determined based on the sensing signal and the electrical parameters that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the surgical operation status of the second operation is determined based on the electrical parameters to be the operation end, and the energy control identifier indicates that energy reduction is not supported / energy stopping is not supported, control the energy delivered to the ultrasonic scalpel 130 to be fixed energy.

[0133] In one embodiment, as shown in FIG2 , the ultrasonic scalpel energy output control system further includes an output prompter 150, which is communicatively connected to the ultrasonic host 110 and is used to provide prompt information to the outside world. The prompt function includes but is not limited to visual, and / or auditory, and / or tactile prompt information, etc. Correspondingly, the ultrasonic host 110, such as the controller 111 of the ultrasonic host 110, is also used to obtain a preset prompt identifier. The preset prompt identifier can be determined by a preset button / switch, or by a preset energy operation state. In this embodiment, when the energy output of the ultrasonic scalpel 130 is reduced, the prompt can be freely changed to improve the safety of the operation.

[0134] For example, a button or switch is provided in the ultrasound host 110 or in the ultrasonic knife 130. If the button is pressed or the switch is turned on, it indicates that a prompt is required. Correspondingly, the prompt flag is set to 1. If the button is not pressed or the switch remains closed, it indicates that no prompt is required.

[0135] For example, a button or key indicating whether prompts are supported is displayed / set in the display device of the ultrasound host 110 (if any) or on the ultrasound host 110, such as on the outer shell of the ultrasound host 110 or on the ultrasonic knife 130. If the button or key supporting prompts is triggered in advance, the prompt flag is set to 1, indicating that prompts are supported / allowed; otherwise, the operation status is set to 0, indicating that prompts are prohibited / not supported.

[0136] By default, the prompt flag is set to 1, indicating that prompting via the prompter 150 is supported / allowed.

[0137] Correspondingly, the output prompter 150 in the ultrasonic knife energy output control system 100 may include one or more devices / components / objects / elements for providing sensory feedback to the user. For example, the output prompter 150 includes any type of visual indication device, including but not limited to an incandescent lamp or LED, a graphical user interface, a display, an analog indicator, a digital indicator, a bar graph display, a digital alphanumeric display, an LCD display screen, an LED display screen, a display device, etc., for providing visual prompts, such as visual change prompts, which are used to indicate the energy output situation, such as reducing the energy output. The output prompter 150 may also include any type of speaker, buzzer, audible computer-generated tone, computer-processed language, a voice user interface (VUI) that interacts with the computer through a voice / language platform, for providing auditory prompts, such as sound change prompts, which are used to indicate the energy output situation, such as reducing the energy output. The output prompter 150 may also include any type of vibration feedback, tactile actuator, etc., for providing tactile prompts, such as tactile change prompts, which are used to indicate the energy output situation, such as reducing the energy output.

[0138] Correspondingly, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to determine whether the blade head state of the blade head 131 is an open state or a closed state according to the sensing signal, determine the surgical operation currently being performed by the ultrasonic blade 130 according to the blade head state, or determine the surgical operation currently being performed by the ultrasonic blade 130 according to the blade head state and electrical parameters, determine the surgical operation state of the surgical operation according to the electrical parameters, control the energy delivered to the ultrasonic blade 130 according to the blade head state, the surgical operation and the surgical operation state, and at the same time control the output prompter 150 to prompt the energy delivered to the ultrasonic blade 130 according to the prompt mark.

[0139] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to control the reduction of energy delivered to the ultrasonic scalpel 130 or the cessation of energy delivery to the ultrasonic scalpel 130 when the sensing signal indicates that the blade state is in the open state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the first operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the electrical parameters indicate that the surgical operation state of the first operation is the operation end state, or the electrical parameters indicate that the surgical operation state of the first operation changes from the operation in progress state to the operation end state. At the same time, according to the prompt mark, the output prompter 150 is controlled to give a corresponding prompt on the energy delivered to the ultrasonic scalpel 130. For example, if the prompt mark indicates support / permission prompt, the output prompter 150 is controlled to give a prompt for the change in reducing the delivered energy or stopping the delivery of the energy. If the prompt mark indicates non-support / prohibition prompt, the output prompter 150 is controlled not to give a prompt, wherein the first operation includes punching or back cutting.

[0140] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to control the reduction of energy delivered to the ultrasonic scalpel 130 when the sensing signal indicates that the blade state is a closed state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the electrical parameters indicate that the surgical operation state of the second operation is a state where the operation is about to end or a state where the operation is ended. At the same time, according to the prompt mark, the output prompter 150 is controlled to give a corresponding prompt on the energy delivered to the ultrasonic scalpel 130, wherein the second operation includes clamping cutting, cutting or coagulation.

[0141] In one usage scenario, the ultrasound host 110, such as the controller 111 of the ultrasound host 110, is also used to control the stop of energy delivery to the ultrasonic scalpel 130 when the sensing signal indicates that the blade state is a closed state, the blade state indicates that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, or the blade state and electrical parameters indicate that the surgical operation currently being performed by the ultrasonic scalpel 130 is the second operation, and the electrical parameters indicate that the surgical operation state of the second operation is a state where the operation is about to end or a state where the operation is ended, and at the same time, according to the prompt mark, control the output indicator 150 to give a corresponding prompt on the energy delivered to the ultrasonic scalpel 130.

[0142] If the energy delivered to the ultrasonic scalpel 130 is controlled to be fixed energy, when the prompt indicator indicates support / permission of the prompt, the output prompter 150 may or may not prompt. When prompting, it is used to prompt that the energy delivered to the ultrasonic scalpel 130 is fixed energy.

[0161] All of the above technical solutions can be combined in any way to form optional embodiments of the present application, and will not be described in detail here.

[0162] FIG7 is a flow chart of an ultrasonic scalpel energy output control method provided in an embodiment of the present application. The ultrasonic scalpel energy output control method is applied to the ultrasonic scalpel energy output control system 100 described in any of the above embodiments. For example, the ultrasonic scalpel energy output control system 100 includes an ultrasonic scalpel 130, a transducer 120, a measuring unit 140, and an ultrasonic host 110, wherein the ultrasonic scalpel 130 includes a scalpel head 131. The scalpel head 131 is used to process tissue, and the scalpel head 131 includes a first scalpel head assembly and a second scalpel head assembly. The first scalpel head assembly and the second scalpel head assembly move relative to each other around an axis so that the scalpel head 131 changes between a first scalpel head state and a second scalpel head state, wherein the first scalpel head state is an open state and the second scalpel head state is a closed state. The ultrasonic scalpel 130 also includes a handle assembly 132, which is connected to the transducer 120 and the scalpel head 131, respectively. The transducer 120 is configured to convert received electrical energy into kinetic energy and transmit the kinetic energy to the scalpel head 131 via the handle assembly 132. The ultrasonic main unit 110 is connected to the transducer 120 and is configured to provide electrical energy to the transducer 120. The specific functions of the various components of the ultrasonic scalpel energy output control system 100 are described above.

[0163] The ultrasonic scalpel energy output control method is implemented by the ultrasonic host 110. The ultrasonic scalpel energy output control method includes: obtaining a sensing signal and / or electrical parameters when and / or after stimulating the ultrasonic scalpel 130, and controlling the energy delivered to the ultrasonic scalpel 130 based on the sensing signal and / or electrical parameters.

[0164] When the sensing signal indicates that the blade tip is in the open state, the energy delivered to the ultrasonic scalpel 130 is controlled to be a fixed energy. For example, when the controller 111 determines that the blade tip is in the open state based on the sensing signal, the controller 111 controls the drive unit 112 to provide a preset electrical energy to the transducer 120. The preset electrical energy is determined by any one or more of a preset voltage, a preset current, or a preset power, so that the transducer 120 provides kinetic energy that matches the preset voltage, preset current, or preset power, thereby controlling the ultrasonic scalpel 130 to output a fixed energy.

[0165] When the sensing signal indicates that the blade head is in the closed state, the energy delivered to the ultrasonic blade 130 is controlled to be a fixed energy.

[0166] In one embodiment, the ultrasonic scalpel energy output control method includes the following steps.

[0167] 201. Acquire electrical parameters of an ultrasonic scalpel energy output control system during operation, where the electrical parameters include at least one of current, voltage, power, impedance, or frequency.

[0168] This step may be implemented by the measuring unit 140 , which may be integrated into the ultrasound host 110 or exist independently of the ultrasound host 110 .

[0169] 202. When the ultrasonic scalpel performs a surgical operation, the surgical operation currently being performed by the ultrasonic scalpel is determined based on the open or closed state of the blade head of the ultrasonic scalpel and the electrical parameters, and the energy delivered to the ultrasonic scalpel is controlled based on the surgical operation currently being performed by the ultrasonic scalpel.

[0170] In one embodiment, the ultrasonic scalpel energy output control system 100 further includes a sensor 133, wherein: the sensor 133 is used to sense the blade state of the blade head 131 to obtain a sensing signal, and the sensor 133 is disposed in the blade handle assembly 132 and / or the blade head.
