Detailed Description

In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. The cases of "target", "original", etc. are similar and will not be described in detail herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Before describing embodiments of the present invention, a description will be given of exemplary reasons why the present RF energy release apparatus described in the background art cannot secure a therapeutic effect on a therapeutic target. For example, the current RF energy-releasing apparatus may include a main control device for controlling the pulse generator to generate a pulse signal and a treatment electrode for fitting on the treatment target, and the pulse signal generated by the pulse generator may be released to the treatment target through the treatment electrode to treat the treatment target through the pulse signal. In practical applications, there is often a case that the adhesion between the therapeutic electrode and the therapeutic target is poor, which results in a low intensity of the pulse signal released to the therapeutic target, and thus the therapeutic effect on the therapeutic target cannot be ensured. From the above, the present RF energy release apparatus cannot determine the fitting degree information between the therapeutic electrode and the therapeutic target, and thus cannot guarantee the therapeutic effect on the therapeutic target, which is to be improved.

Example 1

Fig. 1 is a schematic structural diagram of a radio frequency energy release device according to a first embodiment of the present invention. The embodiment is applicable to the case of releasing radio frequency energy, and is particularly applicable to the case of releasing radio frequency energy when the therapeutic effect of the therapeutic target can be ensured. Referring to fig. 1, the apparatus provided in this embodiment may include: the main control device 110, the treatment electrode 120, the pulse generator 130 and the signal processing device 140, wherein the main control device 110 is respectively connected with the pulse generator 130, the signal processing device 140 and the treatment electrode 120 in a communication way. Wherein,,

a therapeutic electrode 120 for fitting over a therapeutic target to acquire a first signal of the therapeutic target;

the signal processing device 140 is electrically connected with the therapeutic electrode 120, and is configured to acquire a first signal, determine adhesion degree information between the therapeutic electrode 120 and the therapeutic target according to the first signal, and send the adhesion degree information to the main control device 110;

the main control device 110 is configured to determine whether the fitting degree information meets a preset condition, and control the pulse generator 130 to generate a pulse signal when the fitting degree information meets the preset condition, so as to treat the treatment target by releasing the pulse signal to the treatment target through the treatment electrode 120.

The therapeutic electrode 120 may be understood as an electrode that is attached to a therapeutic target, is capable of acquiring a first signal of the therapeutic target, and is capable of releasing a pulse signal to the therapeutic target. The therapeutic target may be understood as a target that needs to be treated by a pulse signal, and may be a human body or a part of a human body, such as a heart, a blood vessel, a face, etc., in combination with an application scenario that may relate to an embodiment of the present invention. The first signal may be understood as a signal acquired from the treatment target by the treatment electrode 120, which may be a physiological signal of the treatment target, for example, the first signal may be an internal electrocardiosignal when the treatment electrode 120 is fitted to a vascular surface inside the heart; the interference signal may also be an interference signal, which is easily generated when the fit degree information between the therapeutic electrode 120 and the therapeutic target is not high, and in practical application, the fit degree information may be understood as the fit degree between the therapeutic electrode 120 and the therapeutic target, and the fit degree information may be, for example, a percentage value, or may be information such as "better" or "worse" in a word description, and in the embodiment of the present invention, the expression form of the fit degree information is not limited specifically.

It can be understood that when the degree of adhesion between the therapeutic electrode 120 and the therapeutic target is sufficient, the first signal collected by the therapeutic electrode 120 can accurately reflect the physiological condition of the therapeutic target, and the intensity of the pulse signal released to the therapeutic target can ensure the therapeutic effect. Accordingly, when the fitting degree is insufficient, the first signal acquired through the therapy electrode 120 may be an interference signal, and the intensity of the pulse signal released to the therapeutic target cannot guarantee the therapeutic effect. Therefore, in order to ensure the therapeutic effect of the rf energy-releasing device, the determination of the degree of fit between the therapy electrode 120 and the therapy target is crucial, and thus the signal processing device 140 is proposed herein. In particular, the method comprises the steps of,

the signal processing device 140 may be understood as a device capable of determining the fitting degree information according to the first signal, which may analyze and process the first signal, and determine the fitting degree information according to the similarity between the first signal and the standard signal, where the standard signal may be understood as a standard form of the first signal, and when the similarity between the first signal and the standard signal is high, it indicates that the fitting degree is better, and when the similarity between the first signal and the standard signal is low, it indicates that there is no better fitting between the treatment electrode and the treatment target, which affects the collection of the first signal, so that the fitting degree information may be determined according to the similarity between the first signal and the standard signal; the first signal is taken as an electrocardiosignal as an example, and the fitting degree information can be obtained according to the intensity or regularity of the electrocardiosignal; of course, the fit information may also be determined by the remaining ways, which are not specifically limited herein.

The main control device 110 may be understood as a device capable of determining whether the fitting degree information satisfies a preset condition, and controlling the pulse generator 130 to generate a pulse signal when the fitting degree information satisfies the preset condition. Of course, the main control device 110 may also serve other functions, which are not specifically limited herein. The preset condition may be understood as a preset condition capable of generating a pulse signal, specifically, a condition capable of ensuring a therapeutic effect of a therapeutic target, for example, a condition that radio frequency energy is released when the fitting degree information is greater than or equal to a preset fitting degree information threshold value, or a condition that a mean value of a plurality of fitting degree information obtained continuously is greater than or equal to a preset mean value threshold value and a variance is less than or equal to a preset variance threshold value is released; etc., and are not particularly limited herein. The pulse signal is understood to be a signal which is capable of treating a therapeutic target, and may be, for example, a high voltage pulse signal. The pulse generator 130 may be understood as a generator capable of emitting a pulse signal.

In the embodiment of the present invention, since the released pulse signal can be ensured to achieve the required therapeutic effect when the fitting degree information satisfies the preset condition, the main control device 110 controls the pulse generator 130 to generate the pulse signal when determining that the fitting degree information satisfies the preset condition, so that the effect of treating the therapeutic target is achieved by releasing the pulse signal to the therapeutic target through the therapeutic electrode 120.

It should be noted that the pulse generator 130 and the main control device 110 may be different devices, and the pulse generator 130 and the main control device 110 are in communication connection with each other; the pulse generator 130 may also be provided in the main control device 110; etc.; in the embodiment of the present invention, the position and connection relationship between the pulse generator 130 and the main control device 110 are not particularly limited.

The embodiment of the invention provides a radio frequency energy release device, which comprises a main control device 110, a treatment electrode 120, a pulse generator 130 and a signal processing device 140, wherein the main control device 110 is respectively in communication connection with the pulse generator 130, the signal processing device 140 and the treatment electrode 120; wherein, the therapeutic electrode 120 is attached to the therapeutic target to collect the first signal of the therapeutic target; the signal processing device 140 is electrically connected with the treatment electrode 120 to acquire a first signal, and determines the fitting degree information between the treatment electrode 120 and the treatment target according to the first signal, and sends the fitting degree information to the main control device 110; the main control device 110 determines whether the fitting degree information satisfies a preset condition, and controls the pulse generator 130 to generate a pulse signal to treat the treatment target by releasing the pulse signal to the treatment target through the treatment electrode 120 when the fitting degree information satisfies the preset condition. In the above technical solution, the signal processing device 140 determines the degree of adhesion between the therapeutic electrode 120 and the therapeutic target, and then the main control device 110 generates the pulse signal for treating the therapeutic target when the degree of adhesion meets the preset condition, thereby effectively ensuring the therapeutic effect on the therapeutic target.

An alternative solution, see fig. 2, is a radio frequency energy release device, further comprising: the channel selection relay 150, the channel selection relay 150 is electrically connected with the main control device 110 and the treatment electrode 120 respectively; the main control device 110 is further configured to send a fit acquisition instruction to the channel selection relay 150; the channel selection relay 150 is configured to acquire a first signal acquired by the therapy electrode 120 when receiving the fitting degree acquisition instruction, and send the first signal to the signal processing device 140, so that the signal processing device 140 acquires the first signal.

Among them, the channel selection relay 150 may be understood as a relay capable of selecting a channel corresponding to a transmission or reception signal. It will be appreciated that in embodiments of the present invention, since there may be multiple channels for connecting the therapy electrode 120 or the signal processing device 140 to the signal processing device 140, a channel selection relay 150 may be provided for facilitating the management and selection of the multiple channels.

In the embodiment of the present invention, the fitting degree acquisition instruction may be used to open a channel between the channel selection relay 150 and the signal processing device 140 and signal processing device 140, so that when the fitting degree acquisition instruction is received, the channel selection relay 150 may acquire the first signal acquired by the therapy electrode 120 and send the first signal to the signal processing device 140, so that the signal processing device 140 acquires the first signal.

According to the technical scheme, the channel selection relay 150 is arranged, and the main control device 110 is matched with the laminating degree acquisition instruction sent to the channel selection relay 150, so that laminating degree information can be determined when the laminating degree information is required to be determined, and effective operation of the radio frequency energy release equipment is ensured.

Optionally, the main control device 110 is further configured to send a radio frequency energy release signal and a pulse signal to the channel selection relay 150; the channel selection relay 110 is further used for treating a target to be treated by releasing the pulse signal generated by the control pulse generator to the target to be treated via the treatment electrode 120 upon receiving the rf energy release signal. Specifically, in order to transmit the pulse signal to the therapy electrode 120, the channel between the channel selection relay 150 and the therapy electrode 120 may be opened, so that the main control device 110 transmits a radio frequency energy release signal to the channel selection relay 150, where the radio frequency energy release signal is used to indicate whether to open the channel between the channel selection relay 150 and the therapy electrode 120, so that the channel selection relay 150 may forward the pulse signal transmitted by the main control device 110 to the therapy electrode 120, thereby treating the therapeutic target. The above scheme can be used for timely treatment when the treatment is required by setting the channel selection relay 150 and matching with the radio frequency energy release signal sent by the main control device 110 to the channel selection relay 150 for opening the channel between the channel selection relay 150 and the treatment electrode 120.

In another alternative solution, referring to fig. 3, the radio frequency energy release device further includes: a display device 160 and a catheter 170 connected to the therapy electrode 120; the display device 160 is electrically connected to the main control device 110; the main control device 110 is further configured to generate a prompt message and send the prompt message to the display device 160 when the fitness information does not meet the preset condition; the display device 160 is also used for displaying prompt information.

The display device 160 may be understood as a device capable of displaying a prompt message, such as a liquid crystal display. The prompt information may be understood as information for prompting adjustment of the catheter 170 connected to the therapy electrode 120, and the catheter 170 may be understood as a tube having one end connected to the therapy electrode 120 and the other end being hand-held.

It will be appreciated that when the fit information does not meet the preset condition, which means that the therapeutic electrode 120 is not effectively fitted to the therapeutic target, it is necessary to make the therapeutic electrode 120 better fit to the therapeutic target in order to ensure the therapeutic effect. It should be noted that, when the therapeutic target is located inside the human body, the position of the therapeutic electrode 120 cannot be directly adjusted at this time, but the position of the therapeutic electrode 120 can be adjusted by adjusting the position of the catheter 170. Specifically, the main control device 110 may generate the prompt information and then send the prompt information to the display device 160, so that the user may adjust the position of the catheter 170 according to the prompt information, so that the therapeutic electrode 120 connected to the catheter 170 is better attached to the therapeutic target, thereby further ensuring the therapeutic effect on the therapeutic target.

Fig. 4 is a schematic structural diagram of a radio frequency energy release device according to a second embodiment of the present invention. The present embodiment provides a device that can be combined with each of the alternatives provided in the above embodiments. In this embodiment, optionally, the radio frequency energy release further includes: the radio frequency energy release switch is a physical switch; the main control device is specifically used for controlling the pulse generator to generate a pulse signal when the fitting degree information meets preset conditions and an opening signal sent by the radio frequency energy release switch is detected, so that the treatment target is treated by releasing the pulse signal to the treatment target through the treatment electrode. Wherein, the explanation of the same or corresponding terms as the above embodiments is not repeated herein. In particular, referring to fig. 4,

the present embodiment provides an apparatus, which may include: a main control device 210, a treatment electrode 220, a pulse generator 230, a signal processing device 240 and a radio frequency energy release switch 250 belonging to a physical switch. Wherein,,

a therapeutic electrode 220 for fitting over a therapeutic target to acquire a first signal of the therapeutic target;

the signal processing device 240 is electrically connected with the therapeutic electrode 220, and is configured to acquire a first signal, determine the fitting degree information between the therapeutic electrode 220 and the therapeutic target according to the first signal, and send the fitting degree information to the main control device 210;

The main control device 210 is specifically configured to control the pulse generator 230 to generate a pulse signal to treat the treatment target by releasing the pulse signal to the treatment target via the treatment electrode 220 when the fitting degree information satisfies a preset condition and the on signal sent by the rf energy release switch 250 is detected.

The rf energy release switch 250 may be a switch for indicating whether to release rf energy, that is, a switch for indicating whether to release a pulse signal, and it should be noted that the switch belongs to a physical switch, that is, a switch with a physical structure, and the physical switch may be a switch such as a push switch, a toggle switch, or a push switch. The on signal may be a signal sent by the rf energy release switch 250 indicating the generation of a pulsed signal.

It should be noted that the pulse signal is released when the fitting degree information satisfies the preset condition, at which time the therapeutic effect can be ensured, but there is no necessity for treatment in this case. Therefore, in the embodiment of the present invention, by setting the rf energy release switch 250, the main control device 210 determines whether there is a treatment requirement currently by determining whether the rf energy release switch 250 sends an on signal, and then controls the pulse generator to generate a pulse signal when the rf energy release switch 250 sends an on signal, that is, to release the pulse signal to the treatment target when there is a treatment requirement, thereby ensuring the life safety of the treatment target.

In the embodiment of the present invention, the rf energy release switch 250 may be connected to the main control device 210, so that the main control device 210 may control the pulse generator 230 to generate a pulse signal when detecting the on signal sent by the rf energy release switch 250; the rf energy release switch 250 may also be connected to the pulse generator 230 at one end and the therapy electrode 220 at the other end, such that the rf energy release switch 250, when depressed, places the pulse generator 230 in communication with the pathway between the therapy electrode 220.

Compared with the scheme that the virtual control is applied to judge whether the treatment requirement exists currently, the technical scheme has the advantages that the control failure condition can not occur due to the fact that liquid exists on the touch screen or a computer is halted, and therefore the safety of the radio frequency energy release equipment is guaranteed.

An optional technical solution, the radio frequency energy release device further includes: the touch screen is provided with a radio frequency energy release control, wherein the radio frequency energy release control is a virtual control; the main control device 210 is specifically configured to control the pulse generator 230 to generate a pulse signal when the fitness information satisfies a preset condition, the rf energy release control is triggered, and the on signal sent by the rf energy release switch 250 is detected, so as to treat the treatment target by releasing the pulse signal to the treatment target via the treatment electrode 220.

The touch screen is understood as an inductive display device capable of receiving input signals such as contacts. The rf energy release control may be understood as a virtual control displayed on the touch screen for indicating whether to release rf energy. In an embodiment of the present invention, when the rf energy release control is triggered and the on signal sent by the rf energy release switch 250 is detected, the main control device 210 determines that there is a current therapeutic requirement, and controls the pulse generator 230 to generate a pulse signal to treat the therapeutic target. That is, the above-mentioned technical solution determines whether there is a need for treatment at present through double judgment, thereby further ensuring the life safety of the treatment target.

Example III

Fig. 5 is a schematic structural diagram of a radio frequency energy release device according to a third embodiment of the present invention. The present embodiment provides a device that can be combined with the various alternatives provided in the above embodiments. In this embodiment, optionally, the radio frequency energy release device further includes: an electrocardiograph acquisition device; the electrocardio acquisition device is used for outputting an R wave gating signal; the main control device is also used for controlling the pulse generator to generate a pulse signal when the fitting degree information meets preset conditions and the R-wave gating signal output by the electrocardio acquisition device is acquired, so that the treatment target is treated by releasing the pulse signal to the treatment target through the treatment electrode. The accuracy of the treatment of the radio frequency energy release device can be improved. Wherein, the explanation of the same or corresponding terms as the above embodiments is not repeated herein. In particular, referring to fig. 5,

The present embodiment provides an apparatus, which may include: a main control device 310, a treatment electrode 320, a pulse generator 330, a signal processing device 340 and an electrocardiograph acquisition device 350. Wherein,,

the therapeutic electrode 320 is used for fitting on the therapeutic target to acquire a first signal of the therapeutic target.

The signal processing device 340 is electrically connected to the therapy electrode 320, and is configured to acquire a first signal, determine the fitting degree information between the therapy electrode 320 and the therapy target according to the first signal, and send the fitting degree information to the main control device 310.

The electrocardiograph acquisition device 350 is used for outputting an R wave gating signal;

the main control device 310 is configured to control the pulse generator 330 to generate a pulse signal when the fitting degree information satisfies a preset condition and the R-wave gating signal output by the electrocardiograph acquisition device 350 is acquired, so as to treat the treatment target by releasing the pulse signal to the treatment target through the treatment electrode 320.

The electrocardiograph collecting device 350 may be used for outputting an R-wave gating signal, and in the embodiment of the present invention, the electrocardiograph collecting device 350 may be attached to a surface of a heart of a human body, collect an electrocardiograph signal of the heart, generate an R-wave gating signal, or deliver a PACE signal to the heart, and the like, so that the collected electrocardiograph signal may be referred to as an external electrocardiograph signal. Accordingly, the first signal acquired through the therapy electrode 320 attached to the interior of the heart may be referred to as an internal electrocardiograph signal. The R-wave gating signal may be understood as a gating signal for instructing the main control device 310 to generate a pulse signal, which may be generated by the electrocardiograph acquisition device 350 upon detecting an R-wave or determining that the external electrocardiograph signal generated by the heart is an R-wave.

It should be noted that when the treatment target is the heart, the pulse signal may not be released to the treatment target through the treatment electrode 320 at any time, but is suitable for being released to the treatment target when the external electrocardiograph signal generated by the heart is in R-wave, and the electrocardiograph acquisition device 350 generates the R-wave gating signal. Therefore, the electrocardiograph acquisition device 350 can output an R-wave gating signal, and when the main control device 310 acquires the R-wave gating signal output by the electrocardiograph acquisition device 350, the pulse generator is controlled to generate a pulse signal, so that the pulse signal is released to a treatment target at the right time, and the treatment effect is further ensured.

An optional technical solution, the main control device 310 is further configured to configure a gating mode of the electrocardiograph acquisition device 350, where the gating mode includes a PACE gating mode or an R-wave gating mode; the electrocardiographic acquisition device 350 is configured to transmit a PACE signal to the heart when configured in a PACE gating mode, and output an R-wave gating signal to the main control device 310 when a difference between a current time and a transmission time of the PACE signal is a preset delay value, wherein the delay value represents a delay in time between the PACE signal and the R-wave.

The gating mode may be used to represent a mode (or mechanism) of generating an R-wave gating signal, and may be, for example, a PACE gating mode or an R-wave gating mode. The PACE gating mode may be understood as a mode in which a PACE signal is first transmitted to the heart, and then an R-wave gating signal is generated when a delay value after the PACE signal is transmitted; an R-wave gating pattern may be understood as a pattern that generates an R-wave gating signal when an R-wave is acquired.

It should be noted that the PACE signal may be understood as a pacemaker signal for triggering the QRS wave of the heart, and thus the heart may be triggered to generate the QRS wave after the electrocardiogram acquisition device 350 transmits the PACE signal to the heart. On this basis, since the PACE signal and the R wave have a relatively fixed delay value in time, that is, a delay value passes after the PACE signal is transmitted, the heart generates the R wave, so that the electrocardiograph device 350 may generate the R wave gating signal (as shown in fig. 6) when the difference between the current time and the transmission time of the PACE signal is the delay value, and output it to the main control device 310, so that the main control device 310 controls the pulse generator to generate the pulse signal.

In the embodiment of the invention, a touch screen can be arranged in the radio frequency energy release equipment, the touch screen can be in communication connection with the main control device, the touch screen displays a gating mode option, the gating mode option can be particularly PACE gating mode option or R-wave gating mode option, a user can input a gating mode selection instruction by touching the touch screen, and the main control device configures the gating mode of the electrocardio acquisition device according to the gating mode selection instruction.

It can be understood that, considering that there are interference signals or QRS waves generated by the heart are unstable due to disease, the accurate detection of the R waves is affected, so as to affect the accuracy of the release timing of the pulse signals, so that the accuracy of the output timing of the R wave gating signals is ensured by sending the PACE signals to the heart by configuring the electrocardiograph acquisition device 350 into the PACE gating mode, thereby ensuring the accuracy of the release timing of the pulse signals and further ensuring the therapeutic effect.

Based on the above scheme, in another alternative technical scheme, the electrocardiograph acquisition device 350 is electrically connected with the main control device 310; the electrocardiograph acquisition device 350 is further configured to acquire an electrocardiograph signal when configured in an R-wave gating mode, and output the R-wave gating signal to the main control device 310 when the electrocardiograph signal is an R-wave.

In other words, the electrocardiographic acquisition device 350 may also be configured in an R-wave gating mode such that when an R-wave of the heart is acquired, an R-wave gating signal (as shown in fig. 7) is generated and output to the main control device 310. The R-wave gating mode and the PACE gating mode are selected in a double mode, so that a user can select according to actual requirements, and experience is good.

The electrophysiological recorder 450 is understood to be a recorder that can record and display the acquired electrophysiological signals. The third signal may be understood as a physiological signal acquired through the therapy electrode 420 after the therapy target is treated.
