 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

现有技术中，射频装置一般采用单极或双极，单极射频装置的作用深度较深，双极射频装置的作用深度较浅，一方面，用户在使用时需要依据不同的需求，更换单极射频装置或双极射频装置，导致治疗效率低下，治疗效率欠佳，另一方面，单极射频装置的返回电极需要贴服于身体的其他部位才能产生深层次的治疗效果，居家单人使用的时候，操作过于麻烦，降低了用户的使用欲望。同时，在治疗过程中，射频电源的两个输出端口所产生的热量会有差异，容易引起射频电源的两端输出的射频能量产生热量差，这种热量差会影响射频电源的射频能量的均匀输出，而不均匀的射频能量会使得治疗效果脱离治疗预期，从而影响射频治疗仪的治疗效果。
本申请提出一种多极射频装置。
在本申请实施例中，请参照图1至图9，所述多极射频装置包括：
射频电源10，具有电极性相反的第一接口和第二接口；
返回电极50；
治疗电极40，包括多个电极片110；
第一开关切换电路30，具有分别电连接于第一接口和第二接口的第一输入端和第二输入端，第一开关切换电路30的第一输出端与治疗电极40电连接，第一开关切换电路30的第二输出端可切换地与返回电极50或部分电极片110电连接，第一输出端和第二输出端分别连通第一输入端和第二输入端；
和/或，第二开关切换电路20，第二开关切换电路20的第三输入端与第一接口连接，第二开关切换电路20的第四输入端与第二接口连接，第二开关切换电路20具有第三输出端和第四输出端；
控制器60，当所述多极射频装置包括所述第一开关切换电路30时，控制器60还具有单极模式和双极模式，于单极模式，控制器60控制第一输出端和第二输出端分别与治疗电极40和返回电极50电连接；于双极模式，控制器60控制第一输出端和第二输出端分别连通至少一个电极片110；
当所述多极射频装置包括所述第二开关切换电路20时，控制器60控制第三输入端和第四输入端分别切换连接第三输出端和第四输出端。
本申请技术方案中，一方面，在射频电源10与治疗电极40及返回电极50之间设置第二开关切换电路20，通过控制第二开关切换电路20以调配治疗电极40及返回电极50与射频电源10的第一接口和第二接口的连接关系，以在本申请的多极射频装置上实现射频电源10的第一接口和第二接口可以交替连接第二开关切换电路20的第三输入端和第四输入端；另一方面，利用第一开关切换电路30改变治疗电极40及返回电极50与第一接口和第二接口的连接关系，以使本多极射频装置可以在单极模式和双极模式之间进行切换，如此，射频电源10第一接口和第二接口可以在正电极和负电极之间不断切换连接，以均匀射频能量的输出，并保障在待治疗部位进行平行和垂直方向上均产生较好的热效应，实现良好的能量三维均匀作用的效果。当然，第二开关切换电路20和第一开关切换电路30可以共同存在，或者仅设置其中一者。
其中，通过控制器60，可以控制第二开关切换电路20中先是第三输入端和第三输出端连通、第四输入端和第四输出端连通，然后转换至第四输入端和第三输出端连通、第三输入端和第四输出端连通，如此，在第二开关切换电路20工作时，治疗电极40和返回电极50分别与第一接口或第二接口连接的时间相等，或是维持在相近的范围内，以均衡第一接口和第二接口的热量。在本实施例中，在第二开关切换电路20中的各个输入端和各个输出端转换连接时，通过控制器60或手动模式另外控制第一开关切换电路30调节治疗电极40的全部电极片110或部分电极片110与第三输出端连接，返回电极50与第四输出端连接，以使治疗电极40和返回电极50分别携带相反的电极性，从而形成单极模式下的多极射频装置；在本实施例中，通过控制器60或手动模式另外控制第一开关切换电路30调节治疗电极40中的多个电极片110分别与第一输出端和第二输出端的连接关系，以使多个电极片110中的至少一者与第一输出端连接，其余的电极片110或其余的电极片110中的至少一者与第二输出端连接，以保障治疗电极40中至少一个电极片110的电极性与其余的电极片110中的至少一者的电极性相反，从而形成双极模式下的多极射频装置。利用上述的第二开关切换电路20和第一开关切换电路30的配合，实现本申请的多极射频装置在单极模式和双极模式下切换的同时，以及射频电源10输出的第一接口和第二接口与第三输入端和第四输入端的连接关系的不断转换，从而使得本申请的多极射频装置的射频能量在输出上和治疗部位上更加均匀，以保障治疗效果。
需要说明的是，本技术方案中所称的电极片110仅设于治疗电极40上。同时，在一次治疗过程中，在单极模式与双极模式之间的切换形成的联合模式中，单极模式输出的总射频能量与双极模式输出的总射频能量趋于相等。第一输入端、第二输入端、第三输入端、第四输入端、第一输出端、第二输出端、第三输出端、第四输出端可以为多分支的总端头也可以是单支端头。
可以理解，依据控制器可一并控制第一开关切换电路30和第二开关切换电路20，也即，在一实施例中，第一开关切换电路30和第二开关切换电路20可以是同一开关切换电路，通过控制器60实现单极模式和双极模式间的切换，以及分别与第一接口和第二接口的切换。也即位于单极模式或双极模式或联合模式时，控制器60可以进一步控制开关切换电路中与治疗电极40和返回电极50的连接端口的相互切换，以实现第一接口和第二接口处的热量差趋向于零；亦或者，该处的开关切换电路仅保留对第一接口和第二接口处的相互切换，保障在一次治疗过程中，射频电源的第一接口和第二接口所分别输出的总射频能量趋于相等，保障治疗效果。
在一实施例中，请参照图1至图5，当所述多极射频装置包括所述第二开关切换电路20时，控制器60，用于控制第二开关切换电路20工作，以控制第三输入端和第四输入端与第三输出端和第四输出端之间的连接至少切换一次。需要说明的是，在治疗过程中，如果正电极和负电极与射频电源10的连接部位保持恒定，射频电源10的第一接口和第二接口容易产生热量差，在此，通过控制器60控制第二开关切换电路20，实现第三输入端和第四输入端分别与第三输出端和第四输出端的连接的不断切换，以使正电极和负电极使得射频电源10产生的热量在第一接口和第二接口上得到均匀分布，以降低第一接口和第二接口的热量差，从而保障了射频电源10上射频能量的均匀输出。
具体而言，在本实施例中，请参照图1和图4，控制器60，用于控制第二开关切换电路20工作，以控制第三输入端和第四输入端与第三输出端和第四输出端之间的连接以第一预设周期进行切换。如此，控制器60依据预设的算法程序，以第一预设周期控制第二开关切换电路20的转换频率，在一具体实施例中，一次治疗在治疗阶段持续时间范围设置在20ms-12s，控制器60可以控制第二开关切换电路20的转换时间范围设置在0.1ms-2ms，以提高射频能量的均匀输出，从而保障治疗效果。此外，控制器60还可以进入自定义模式，依据用户自身的使用习惯，对设定第一预设周期。
在一实施例中，请参照图1至图5，当所述多极射频装置包括所述第一开关切换电路30时，控制器60，用于控制第一开关切换电路30工作，以控制第一输出端和第二输出端在单极模式和双极模式之间至少切换一次。在单极模式下，治疗电极40上的电极片110的电极性相同，例如均为正极，返回电极50的电极性相同，例如均为负极，此时的治疗电极40和返回电极50在第一开关切换电路30在控制下，保持相反的电极性，而因为治疗电极40和返回电极50对应的人体部位间隔较大，治疗电极40的电极片110上输出的射频能量可以作用到深层次的组织，以实现对待治疗部位进行垂直方向上的治疗目的。在双极模式下，治疗电极40上至少存在一个电极片110的电极性与其余的电极片110的电极性相反，而由于电极性相反的两个电极片110在治疗电极40上，决定了双极模式下射频能量在人体的通路较短，射频能量只能作用于人体较浅的部位，以实现对待治疗部位进行平行方向上的治疗目的。如此，通过控制器60控制第一开关切换电路30，实现单极模式和双极模式的切换，以在一次治疗过程中，单极模式和双极模式各自输出的射频能量相等，可保障本申请的多极射频装置可以实现立体上的热效应分布，从而提升治疗效果。
具体而言，在本实施例中，请继续参照图4，控制器60，用于控制第一开关切换电路30工作，以控制第一输出端和第二输出端在单极模式和双极模式以第二预设周期进行切换。如此，用户可以依据自身需求，选择预设好的切换周期，利用控制器60执行第二预设周期指令，以控制该多极射频装置分别在单极模式和双极模式各自的工作时长以及切换时间，亦或者，用户进入自定义模式，选择合适自身的工作周期，并将自定义的数据保存至控制器60中，以使控制器60依据自定义的数据进行单极模式和双极模式之间的切换，从而使得电极片110的作用区域可以实现相对待治疗区域的平行方向和垂直方向上的热效应分布，以形成较好的三维治疗效果。在此，需要说明的是，不管是系统预设或自定义的周期，在一次治疗过程中，单极模式和双极模式各自输出的射频能量相等。另外，在其他实施例中，需要在使用过程中手动切换单极模式和双极模式，或依据使用状况而随时改变单极模式或双极模式的工作时间，如此，用户可以通过手动操控治疗手柄100上的开关切换按钮130，将切换指令输出至控制器60，通过控制器60进行单极模式和双极模式之间的切换。
不失一般性，在一实施例中，控制器60可以是单片机、DSP及FPGA等微处理器，也可以是射频治疗仪专用芯片来实现，此处不做限制。本领域的技术人员能够通过在控制器60中集成一些硬件电路以及预设的算法程序，利用控制器60运行算法程序以实现本申请的多极射频装置在单极模式和双极模式之间的自动切换以及第二开关切换电路20的工作。用户也可以根据自身的需求选择在单极模式或双极模式下对应的射频频率或第二开关切换电路20的工作时长。
不失一般性，请继续参照图6至图9，治疗电极40中的多个电极片110可以呈阵列排布，或是呈一字排开，或是呈圆周分布等；在双极模式下，各个电极片110与相邻的电极片110的电极性可以相同，也可以不同，例如电极片110以行为单位，正负交错设置，也即一行电极片110的电极性为正，与之邻行的电极片110的电极性为负，或者，每一电极片110与其相邻的电极片110的电极性均相反，也即每一行与每一列中的电极片110均呈正负交错设置。当然，电极片110的这种排列方式也可以适用于单极模式下，以增强治疗电极40的电极片110所携带的单一电极性的射频能量。
进一步地，在一实施例中，请参照图1和图6至图9，返回电极50的抵接面积大于治疗电极40的抵接面积。需要说明的是，电极与皮肤之间的接触面积的大小关系射频能量的热效应的大小，在形成的射频回路中的两处接触面积中，射频能量的热效应主要产生于接触面积较小的部位，在此，抵接面积是电极片110或返回电极50与待治疗部位的皮肤的接触面积，如此，在单极模式下，射频热效应主要通过治疗电极40作用于待治疗部位而产生，以保障治疗效果。当然，在其他实施例中，返回电极50的抵接面积也可以略小于电极片110的抵接面积。
具体而言，在本实施例中，请继续参照图1和图6至图9，多极射频装置具有握持部120，返回电极50设于握持部120。不失一般性，多极射频装置包括治疗手柄100，握持部120位于治疗手柄100的中部，用户使用时一般用手握住握持部120，也即用户的手掌与返回电极50连通，如此，在单极模式下，治疗电极40的电极片110的电极性与返回电极50的电极性相反，在此，握持部120相当于返回电极50，电极片110发出的射频能量可对待治疗部位产生热效应，从而实现治疗效果，相较于另外设置返回电极50与人体的其他部位接触从而形成的回路，返回电极50设于握持部120提升了用户使用该多极射频装置便利性，适合居家个人用户。当然，在其他实施例中，返回电极50可以设置在治疗手柄100另外凸设的分支上，该分支在治疗电极40的电极片110与待治疗部位接触时，返回电极50也可以与人体接触，以形成回路。亦或者，在另一实施例中，多极射频装置为大型治疗仪设备，应用于医院或美容机构的等场所，其中治疗电极40和返回电极50各自有连通结构与治疗主机连接，第二开关切换电路20和第一开关切换电路30设置在治疗电极40和返回电极50的交接处。
在一实施例中，射频电源10包括一个供电电源或多个互相独立的供电电源，供电电源与第二开关切换电路20连接。需要说明的是，供电电源可以是外接电源或可充电锂电池，且供电电源可以是连续输出电源或脉冲输出电源或者连续与脉冲共同输出电源；当采用一个供电电源时，可以减少该多极射频装置的体积，当设置为多个相互独立的供电电源时，多个供电电源分别与第二开关切换电路20的第三输入端和第四输入端连接。不失一般性，射频电源10内还包括有频率调整器，不管是在第二开关切换电路20工作时还是第一开关切换电路30工作时，频率调整器都可以调整射频电源10输出的射频频率，从而调节该多极射频装置的治疗档位，以取得更加有效的治疗效果。
本申请还提出一种多极射频装置的控制方法，应用于如上述的多极射频装置，请参照图5，该多极射频装置的控制方法包括：
判断用户输入信号；
若信号为单极模式，则进入单极模式，控制第一输出端和第二输出端分别与治疗电极40和返回电极50电连接，以使治疗电极40的多个电极片110的电极性相同；
若信号为双极模式，则进入双极模式，控制第一输出端和第二输出端分别连通至少一个电极片110，以使治疗电极40中至少一个电极片110的电极性与其余的电极片110的电极性相反；
若信号为联合模式，则控制所述第一输出端和所述第二输出端在所述单极模式和所述双极模式之间至少切换一次。
其中，用户依据对待治疗部位的位置，对使用单极模式、双极模式或共同使用单极模式或双极模式进行判断，依据判断结果，对控制器60下达相应结果的执行信号，本多极射频装置的控制方法是基于用户对待治疗部位相对皮肤深浅情况的判断的结果。
在本实施例中，当待治疗部位相对皮肤较深时，用户输入单极模式信号，控制器60控制第一开关切换电路30切换至单极模式，在单极模式下，第一开关切换电路30基于控制器60的控制，用于将治疗电极40与第三输出端连接，返回电极50与第四输出端连接，以使治疗电极40与返回电极50保持相反的电极性，由于治疗电极40和返回电极50在人体上形成的通路较长，治疗电极40可以对较深待治疗部位产生热效应，以实现射频能量深入皮肤内部。
当待治疗部位相对皮肤较浅时，用户输入双极模式信号，控制器60控制第一开关切换电路30切换至双极模式，在双极模式下，治疗电极40上的一部分电极片110与第三输出端连接，另一部分电极片110与第四输出端连接，以使治疗电极40上至少具有一个电极片110的电极性与其余电极片110的电极性相反，由于治疗电极40上的携带相反电极性的电极片110在人体上形成的通路较短，相反两部分电极片110中抵接面积较小的电极片110可以对较浅的待治疗部位产生热效应。
当待治疗部位相对皮肤的深浅适中，适合单极模式和双极模式的切换使用时，也即联合模式，用户输入联合模式的信号，控制器60控制第一开关切换电路30在单极模式和双极模式之间至少切换一次。具体而言，若仅依靠单一的一种模式无法进行有效治疗，则可在初始启动本申请多极射频装置时，工作模式可以是单极模式或双极模式，持续一段时间后，从单极模式切换至双极模式，或者，从双极模式切换至单极模式，整个治疗阶段中的工作模式至少切换一次。由于单极模式和双极模式下的作用区域不同，为了扩大作用区域，提升治疗效果，本实施例采取单、双极模式切换的工作模式，使得待治疗部位在相对皮肤并行和垂直的方向均达到预期的治疗效果。需要说明的是，在本实施例中，在联合模式的一次治疗过程中，单极模式输出的总射频能量与双极模式输出的总射频能量相等，也即单极模式与双极模式分别对应的工作时间内，单极模式输出的总射频能量等于双极模式输出的总射频能量。
在一实施例中，在一实施例中，在双极模式或单极模式下，控制第三输入端和第四输入端与第三输出端和第四输出端之间的连接至少切换一次。可以理解，在单极模式或双极模式下，包括仅是单极模式、仅是双极模式、仅是联合模式的情况，第二开关切换电路20基于控制器60的控制，可以使第三输入端和第四输入端分别与第三输出端和第四输出端连通，或使第三输入端和第四输入端分别与第四输出端和第三输出端连通，或是第三输入端和第四输入端与第三输出端和第四输出端之间的连接至少切换一次，以保障在单极模式或双极模式下，射频电源10的两个接口输出相对均匀的射频能量，达到较佳的治疗效果。
进一步地，在一实施例中，多极射频装置的控制方法还包括在双极模式或单极模式下，控制第三输入端和第四输入端与第三输出端和第四输出端之间的连接以第一预设周期进行切换。具体而言，在进行治疗时，为保障射频电源10的第一接口和第二接口的热量差可以趋向于零，也即，在第二开关切换电路20工作时，治疗电极40和返回电极50分别与第一接口或第二接口连接的时间相等，或是维持在相近的范围内。如此，通过控制器60设定第二开关切换电路20以第一预设周期工作，在单极模式或双极模式下，第二开关切换电路20基于控制器60的控制，以第一预设周期不断切换第三输入端和第四输入端与第三输出端和第四输出端之间的连接，以使射频电源10的第一接口和第二接口可以相对均匀输出射频能量，以达到预期的治疗效果。
进一步地，在本实施例中，在双极模式或单极模式下，第三输入端和第四输入端与第三输出端和第四输出端的切换连通，在一次治疗过程中，治疗电极40中任意一个电极片110，连接第一接口所产生的热量为W1、连接第二接口所产生的热量为W2，0.5≤W1/W2≤2.0。需要说明的是，W1和W2代表一次治疗过程中，治疗电极40任意一个电极片110分别对应第一接口和第二接口产生的累积热量。可以理解，不管单极模式或双击模式下，在一次治疗时间中，这里所说的W1和W2为电极片110分别对应第一接口和第二接口各自工作的时间与所对应的功率的乘积，更具体地反应在第一接口和第二接口各自输出在电极片110上的射频能量。也即，在一次治疗过程中，第一接口和第二接口分别对治疗电极40产生的射频能量之比的范围在0.5至2.0之间，在一具体实施例中，W1/W2可以是0.5、1、或2。
在一实施例中，多极射频装置的控制方法还包括控制第一输出端和第二输出端在单极模式和双极模式以第二预设周期进行切换。基于用户对待治疗部位相对皮肤的深浅较为综合，则在治疗过程中，通过控制器60控制第一开关切换电路30以第二预设周期工作。具体而言，初始启动本申请多极射频装置，其所处的工作模式可以是单极模式或双极模式中的一种模式，然后将以第二预设周期将切换至另一种模式，整个治疗阶段中的工作模式为联合模式以第二预设周期进行切换工作，但需保障在一次治疗过程中，联合模式下的单极模式输出的总射频能量与双极模式输出的总射频能量相等。由于单极模式和双极模式下的作用区域不同，本实施例采取单、双极模式切换的工作模式，使得待治疗部位在相对皮肤并行和垂直的方向均达到预期的治疗效果。当然，用户也可以依据自身实际待治疗部位的调整和变化，利用控制器60进行单极模式和双极模式自定义的周期进行治疗，亦或者，通过开关切换按钮130手动输入指令至控制器60，通过控制器60进行单极模式和双极模式间的切换。
进一步地，在本实施例中，于所述联合模式，在一次治疗过程中，单极模式下所产生的热量为W3，双极模式下所产生的热量为W4，0.5≤W3/W4≤2。需要说明的是，W3和W4代表在联合模式下，在一次治疗过程中，单极模式和双极模式分别累积产生的热量。可以理解，在联合模式中，这里所说的W3和W4分别为单极模式下和双极模式下在一次治疗时间中各自工作的时间与所对应的功率的乘积，也即单极模式对深层待治疗部位所做产生的热量和双极模式对浅层待治疗部位所产生的热量，以使待治疗部位相对皮肤的平行和垂直方向上各自的热效应效果的量化比值在0.5至2之间，可实现本申请的多极射频装置在待治疗部位产生三维均匀的热效应，从而实现更佳的治疗效果。在一具体实施例中，W3/W4可以是0.5、1、或2。
为更好实现多极射频装置的输出能量控制，在一实施例中，其中，多极射频装置的控制方法还包括：
获取治疗电极40的电极片110的温度；
判断电极片110的温度是否超出预设的安全温度阀值；
若是，控制射频电源10停止射频能量输出；
若否，控制射频电源10维持有效的射频能量输出。
在本实施例中，可以将温度传感器设置于治疗电极40上，以检测任意一个电极片110上的温度，在此，不管是单极模式、双击模式、联合模式或第二开关切换电路是否共同或单独工作，只要本申请的多极射频装置处于工作中，温度传感器均对电极片110进行温度检测。
需要说明的是，射频治疗仪的有效治疗温度在38℃至48℃之间，在此温度范围内，治疗电极40上的电极片110可以有效的对待治疗部位产生热效应，从而达到治疗目的，在一具体实施例中，依据不同的档位，安全温度阀值可以设置为45℃、48℃或49℃。如此，根据温度传感器检测到的电极片110上的温度，并将此温度与安全温度阀值进行比对，具体地：
当大于安全温度阀值时，控制器60控制射频电源10停止输出射频能量；当小于或等于安全温度阀值时，控制器60耦控制射频电源10维持有效的能量输出。
本申请还提出一种射频治疗仪，该治疗仪包括多极射频装置，该多极射频装置的具体结构参照上述实施例，由于本射频治疗仪采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
