[0046] Medical energy devices are used to cut, ablate, and coagulate patient tissues by providing energy such as ultrasound, radio frequency, plasma, and laser. They are widely used in surgical procedures such as soft tissue cutting and coagulation. However, during use, medical energy devices generate smoke, which can interfere with the operator's surgical field of vision and affect the surgical procedure. For example, the smoke is a gaseous substance generated during surgery, which is generally composed of 95% water or water vapor and 5% cell debris in particulate form.

[0047] The smoke treatment device and medical energy device provided in this application embodiment are equipped with a power supply component, a first electrode and a second electrode. A high-voltage electric field is generated between the first electrode with a positive high-voltage electrical signal and the second electrode with a negative high-voltage signal, that is, a strong electric field. The smoke generated during the operation is electrically separated in the strong electric field. After the tiny particles in the smoke combine with the particles and become negatively charged, they tend to discharge towards the first electrode and are deposited, thereby reducing or removing the smoke during the operation.

[0048] In one exemplary embodiment, such as Figure 1 As shown, this application provides a smoke treatment device for use in medical energy equipment. The smoke treatment device includes:

[0049] First electrode 110;

[0050] The power supply component 130 has a first output terminal connected to the first electrode 110, and outputs a positive high voltage signal to the first electrode 110.

[0051] The second electrode 120 is embedded in the medical energy device. The second electrode 120 is connected to the second output terminal of the power supply component 130. The second electrode 120 receives the negative high voltage signal output by the power supply component 130. The first electrode 110 and the second electrode 120 work together on the same conductive medium to form an electric circuit to generate a high voltage electric field, which eliminates smoke.

[0052] The magnitudes of the positive and negative high-voltage electrical signals can be set according to actual conditions, and are not limited in this embodiment.

[0053] Specifically, when performing surgery on a patient using a medical energy device equipped with a smoke treatment device, the first electrode 110 is in contact with the patient's skin surface (attached to the patient's thigh or buttocks). When the medical energy device outputs energy, the power supply component 130 outputs a positive high-voltage electrical signal to the first electrode 110 and a negative high-voltage signal to the second electrode 120. The large voltage difference between the first electrode 110 and the second electrode 120 generates a high-voltage electric field. The tiny particles in the smoke generated during the surgery are electrically separated by the high-voltage electric field. After the particles combine and become negatively charged, they tend to discharge and deposit on the first electrode 110 (anode surface), thereby reducing intraoperative smoke and ensuring the efficient completion of the surgical operation.

[0054] It should be noted that the voltage difference between the first electrode 110 and the second electrode 120 can be 3KV to 15KV, and is usually set between 3KV and 8KV.

[0055] The aforementioned smoke treatment device, by providing a power supply component 130, a first electrode 110, and a second electrode 120, generates a high-voltage electric field between the first electrode 110 carrying a positive high-voltage electrical signal and the second electrode 120 carrying a negative high-voltage electrical signal. The smoke generated during the operation is electrically separated in the high-voltage electric field. After the tiny particles in the smoke combine with the particles and become negatively charged, they tend to discharge towards the first electrode 110 and be deposited, thereby reducing or removing smoke during the operation.

[0056] In one embodiment, the power supply component includes a first rectifier circuit and a second rectifier circuit;

[0057] One end of the first rectifier circuit is connected to the mains power, and the other end is connected to the first electrode.

[0058] One end of the second rectifier circuit is connected to the mains power, and the other end is connected to the second electrode.

[0059] Specifically, the first rectifier circuit is used to rectify the mains power to output a positive high voltage signal to the first electrode 110, and the second rectifier circuit is used to rectify the mains power to output a negative high voltage signal to the second electrode 120. It can be understood that the circuit structure of the first rectifier circuit and the second rectifier circuit can be set according to the actual situation, as long as they can meet the function of outputting negative high voltage signal and positive high voltage signal.

[0060] In this embodiment, the power supply component includes a first rectifier circuit connected to the first electrode 110 and a second rectifier circuit connected to the second electrode 120, so as to output a positive high voltage signal to the first electrode 110 and a negative high voltage signal to the second electrode 120 respectively, thereby generating a high voltage electric field between the first electrode 110 and the second electrode 120, thereby reducing or removing smoke during the operation.

[0061] In one embodiment, such as Figure 2 As shown, the first rectifier circuit includes a first transformer T1, a first voltage multiplier unit, a first capacitor C1, and a rectifier diode Dx; wherein, the number of the first voltage multiplier unit is one or more;

[0062] When there is only one voltage multiplier unit, the two ends of the primary winding of the first transformer T1 are used to connect to the mains power. The two ends of the secondary winding of the first transformer T1 are respectively connected to the first input terminal and the second input terminal of the first voltage multiplier unit. The first output terminal of the first voltage multiplier unit is connected to the positive terminal of the rectifier diode Dx and the first electrode 110 through the first capacitor C1. The second output terminal of the first voltage multiplier unit is connected to the negative terminal of the rectifier diode Dx.

[0063] When there are multiple first voltage multiplier units, the two ends of the primary winding of the first transformer T1 are used to connect to the mains power. Each first voltage multiplier unit is connected in series in sequence. The first input terminal and the second input terminal of the first first voltage multiplier unit are respectively connected to the two ends of the secondary winding of the first transformer T1. The first output terminal of the last first voltage multiplier unit is connected to the positive terminal of the rectifier diode Dx and the first electrode 110 through the first capacitor C1. The second output terminal of the last first voltage multiplier unit is connected to the negative terminal of the rectifier diode Dx.

[0064] The number of the first voltage multiplier units is set according to the magnitude of the positive high voltage signal; the turns ratio of the primary and secondary sides of the first transformer T1 can be set according to the actual situation, and is not limited in this embodiment.

[0065] Specifically, Figure 2 An exemplary schematic diagram of the connection structure of the first rectifier circuit when there are multiple first voltage multiplier units is shown, such as... Figure 2As shown, the mains power U is boosted by the first transformer T1 and then enters the first voltage multiplier unit. Each first voltage multiplier unit is used for boosting voltage. When the secondary voltage of the first transformer T1 is positive at the top and negative at the bottom, the rectifier diode Dx is turned on. The current passes through the rectifier diode Dx to charge the first capacitor C1 so that the voltage on the first capacitor C1 reaches the positive high voltage signal +HV1 and is output to the first electrode 110.

[0066] It should be noted that the first voltage multiplier unit in the first rectifier circuit is used for grounding.

[0067] In this embodiment, by configuring a first transformer T1, a first capacitor C1, a rectifier diode Dx, and a corresponding number of first voltage multiplier units in the first rectifier circuit, a positive high voltage signal +HV1 is output to the first electrode 110, which facilitates the reduction or removal of smoke during the operation.

[0068] In one embodiment, such as Figure 3 As shown, the first voltage multiplier unit includes a second capacitor C2, a third capacitor C3, a first diode D1, and a second diode D2;

[0069] The other end of the second capacitor C2 is connected to the positive terminal of the first diode D1 and the negative terminal of the second diode D2, respectively. The negative terminal of the first diode D1 is connected to one end of the third capacitor C3, and the other end of the third capacitor C3 is connected to the positive terminal of the second diode D2.

[0070] In this circuit, one end of the second capacitor C2 is the first input terminal of the first voltage multiplier unit, the cathode of the first diode D1 is the second input terminal of the first voltage multiplier unit, the cathode of the second diode D2 is the first output terminal of the first voltage multiplier unit, and the anode of the second diode D2 is the second output terminal of the first voltage multiplier unit.

[0071] In the specific implementation, the mains power U is used as the input signal. After being stepped up by the first transformer T1, the output is U1 (the step-up factor is determined by the number of turns on the primary and secondary sides of the first transformer T1). When the secondary voltage of the first transformer T1 is positive at the top and negative at the bottom, the first diode D1 is turned on and the second diode D2 is turned off. The current flows through the first diode D1 to charge the second capacitor C2, charging the voltage on the second capacitor C2 to a value close to the peak value of U1, 1.414U1, and keeping it basically unchanged. When the secondary voltage of the first transformer T1 is negative at the top and positive at the bottom, the second diode D2 is turned on and the first diode D1 is turned off. At this time, the voltage Uc1 = 1.414U1 on the second capacitor C2 is added in series with the power supply voltage U1. The current flows through the second diode D2 to charge the third capacitor C3, and the charging voltage Uc2 = 1.414U1. After repeated charging, the voltage on the third capacitor C3 will be approximately 1.414U1, which is twice the voltage of the first transformer T1 electrode. This can be called a voltage doubler rectifier circuit. Adding a first voltage doubler unit to the voltage doubler circuit can form a voltage tripler rectifier circuit. It can be understood that by setting the number of first voltage doubler units, a positive high voltage signal +HV1 can be output to the first electrode 110.

[0072] It should be noted that, Figure 3 The second capacitor C2' and the first diode D1' both belong to another first voltage multiplier unit, which will not be described in detail in the embodiments of this application.

[0073] In one embodiment, the second rectifier circuit includes a second transformer T2 and a second voltage multiplier unit; wherein the number of second voltage multiplier units is one or more.

[0074] When there is only one second voltage multiplier unit, the two ends of the primary winding of the second transformer T2 are used to connect to the mains power, the two ends of the secondary winding of the second transformer T2 are respectively connected to the first input terminal and the second input terminal of the second voltage multiplier unit, and the output terminal of the second voltage multiplier unit is connected to the second electrode 120.

[0075] When there are multiple second voltage multiplier units, the two ends of the primary winding of the second transformer T2 are used to connect to the mains power. Each second voltage multiplier unit is connected in series in sequence. The first input terminal and the second input terminal of the first second voltage multiplier unit are respectively connected to the two ends of the secondary winding of the second transformer T2. The output terminal of the last second voltage multiplier unit is connected to the second electrode 120.

[0076] The number of the second voltage multiplier units is set according to the magnitude of the negative high voltage signal; the turns ratio of the primary and secondary sides of the second transformer T2 can be set according to the actual situation, and is not limited in this embodiment.

[0077] Specifically, Figure 4An exemplary schematic diagram of the connection structure of the second rectifier circuit when there are multiple second voltage multiplier units is shown, such as... Figure 4 As shown, the mains power U is stepped up by the second transformer T2 and then enters the second voltage multiplier unit. Each second voltage multiplier unit is used to step up the voltage so as to output a negative high voltage signal -HV2 to the second electrode 120.

[0078] It should be noted that the first second voltage multiplier unit in the second rectifier circuit is grounded, and the ground to which the first voltage multiplier unit and the second voltage multiplier unit are connected is the same.

[0079] In this embodiment, by configuring a second transformer T2 and a corresponding number of second voltage multiplier units in the second rectifier circuit, a negative high-voltage electrical signal -HV2 is output to the second electrode 120, which facilitates the generation of a high-voltage electric field with the positive high-voltage electrical signal +HV1 applied to the first electrode 110, thereby reducing or removing smoke during the operation.

[0080] In one embodiment, such as Figure 5 As shown, the second voltage multiplier unit includes a fourth capacitor C4, a fifth capacitor C5, a third diode D3, and a fourth diode D4;

[0081] The other end of the fourth capacitor C4 is connected to the positive terminal of the third diode D3 and the negative terminal of the fourth diode D4, respectively. The negative terminal of the third diode D3 is connected to one end of the fifth capacitor C5, and the other end of the fifth capacitor C5 is connected to the positive terminal of the fourth diode D4.

[0082] Among them, one end of the fourth capacitor C4 is the first input terminal of the second voltage multiplier unit, the negative terminal of the third diode D3 is the second input terminal of the second voltage multiplier unit, and the positive terminal of the fourth diode D4 is the output terminal of the second voltage multiplier unit.

[0083] Specifically, the method of obtaining the negative high voltage signal -HV2 by using the second voltage multiplier unit is the same as the method of obtaining the positive high voltage signal +HV1 by using the first voltage multiplier unit, and will not be repeated in this embodiment.

[0084] It should be noted that, Figure 5 The fourth capacitor C4' and the third diode D3' both belong to another first voltage multiplier unit. Similarly, it can be deduced that the fourth capacitor C4... n Third diode D3 n All of them belong to the last second voltage multiplier unit in the second rectifier circuit, and will not be described in detail in the embodiments of this application.

[0085] In one embodiment, such as Figure 6 As shown, the smoke treatment device also includes a sensing component 140 and a signal control component 150;

[0086] The sensing component 140 is connected to the energy output component and the signal control component 150 of the medical energy device, respectively. The signal control component 150 is connected to the energy output component and the power supply component 130, respectively.

[0087] Specifically, the sensing component 140 is used to output a corresponding sensing signal to the signal control component 150 when it senses that the energy output component is outputting energy. Upon receiving the sensing signal output by the sensing component 140, the signal control component 150 instructs the power supply component 130 to output a negative high-voltage electric signal -HV2 to the second electrode 120. A high-voltage electric field is generated between the first electrode 110 with a positive high-voltage electric signal +HV1 and the second electrode 120 with a negative high-voltage signal -HV2. The smoke generated during the operation is electrically separated in the high-voltage electric field. After the tiny particles in the smoke combine with the particles and become negatively charged, they tend to discharge towards the first electrode 110 and are deposited, thereby reducing or removing the smoke during the operation.

[0088] It is understandable that the model of the sensing component 140 can be set according to the actual situation, as long as it can realize the function of sensing whether the energy output component is outputting energy; the model of the signal control component 150 can be set according to the actual situation, as long as it can realize the function of indicating the output of the negative high voltage signal -HV2 by the power supply component 130.

[0089] For example, the energy output component may include a cutting tool for outputting energy and an operating handle connected to the cutting tool. An energy output control button is provided on the operating handle. When the user triggers the energy output control button, the energy output component can be instructed to output energy. The sensing component 140 is used to sense the triggering of the energy output control button and outputs a sensing signal to the signal control component 150. The signal control component 150 can be a switch and closes the switch when it receives the sensing signal, so that the power supply component 130 can output a negative high voltage signal -HV2 to the second electrode 120 through the signal control component 150.

[0090] In this embodiment, by providing a sensing component 140 and a signal control component 150, the power supply component 130 outputs a negative high-voltage electrical signal -HV2 to the second electrode 120 when the energy output component is outputting energy, thereby reducing or removing smoke in a timely manner during the operation and reducing the amount of smoke inhaled by the user.

[0091] In one embodiment, the outer periphery of the second electrode 120 is wrapped with an insulating material.

[0092] Specifically, the outer periphery of the second electrode 120 is wrapped with insulating material and then embedded in the energy output component to prevent electric shock from contact with the user and improve safety.

[0093] In one exemplary embodiment, this application also provides a medical energy device, including a main unit, an energy output component, and the aforementioned smoke treatment device;

[0094] The energy output component is connected to the main unit and the smoke treatment device respectively, wherein the second electrode in the smoke treatment device is embedded in the energy output component.

[0095] Among them, medical energy devices include medical devices for outputting energy. In this embodiment of the application, an ultrasound surgical device is used as an example for illustration.

[0096] Specifically, the main unit is used to output energy to the energy output component. During the energy output process, the smoke treatment device starts working simultaneously to effectively reduce or eliminate the smoke generated during surgery.

[0097] To facilitate understanding by those skilled in the art, the specific structure of a medical energy device will be described below with reference to a concrete example, using an ultrasound surgical device as an example. Figure 7 As shown, the first electrode 110 can be a patient contact end, the second electrode 120 can be an electrode plate, the power supply component 130 can be a power module, the sensing component 140 can be a sensor device, the signal control component 150 can be a signal controller, and the medical energy device includes an operating handle and a blade connected to the operating handle. The operating handle is provided with an energy output control button for controlling the energy output, and the electrode plate is located inside the sleeve of the operating handle.

[0098] When the sensor device detects that the energy output control button has been triggered and the blade is outputting energy, energy lines 1 and 2 are connected to the ultrasound host, and ports 2 and 3 are connected to the transducer of the operating handle. This converts electrical energy into mechanical energy to control the operating end (blade) to act on the patient's tissue for surgical operation. The signal controller receives the signal from the sensor device and closes the switch, so that the negative high-voltage electric signal generated by the power module acts on the electrode at the tip through port 1 and the conductive wire. The positive high-voltage electric signal generated by the power module is output to the patient contact end. The electrode plate and the patient contact end generate a high-voltage electric field. The generated surgical smoke particles are electrically separated by the high-voltage electric field generated by the electrode at the front end of the conductive wire. After the particles combine and become negatively charged, they tend to discharge and deposit on the anode surface (the patient's body is positively charged), thereby reducing intraoperative smoke during the operation.

[0099] In one embodiment, the grounding of the energy output component is different from that of the smoke treatment device.

[0100] Specifically, the grounding of the smoke treatment device includes the grounding of the first voltage multiplier unit and the second voltage multiplier unit. The grounding of the energy output component is different from that of the smoke treatment device, so as to avoid electric shock caused by sharing the ground with patients or users and improve safety.
