Description
技术领域
本公开涉及基于能量的消融仪器的使用。更具体而言,本公开针对消融装置电路。
背景技术
在诸如癌症的疾病的治疗中,已经发现某些类型的癌细胞在升高的温度(其略微低于在正常情况下对健康细胞造成损伤的温度)下变性。这些类型的治疗一般被称为高热治疗,它们通常利用电磁辐射将疾病细胞加热到超过41°的温度,同时使相邻健康细胞保持在将不会发生不可逆的损坏的较低的温度上。其他利用电磁辐射对组织加热的程序还包括组织的消融和凝固。这样的消融程序,例如针对月经过多执行的消融程序,通常被完成为使目标组织消融并凝固,从而使组织变性或者杀死组织。很多利用电磁辐射治疗的程序和装置类型是本领域已知的。这样的治疗通常用在对诸如前列腺、心脏、肝脏、肺、肾脏和乳房的组织和器官的治疗中。
一种非侵入式程序一般涉及通过微波能量的使用对皮肤下面的组织(例如,肿瘤)进行处理。所述微波能量能够以非侵入的方式穿透皮肤抵达下面的组织。但是,这一非侵入式程序可能导致对健康组织的不必要的加热。因而,微波能量的非侵入式使用需要大量的控制。
当前,有几种类型的使用中的微波探头,例如,单极、双极(dipole)和螺线探头。一种类型的是单极天线探头,其由暴露在探头末尾的单个细长的微波导体构成。所述探头通常被电介质套管所围绕。第二种类型的常用微波探头是双极天线,其由同轴构造构成,该构造具有内导体和外导体并采用电介质接头隔离开内导体的一部分。可以将内导体耦合至对应于第一双极发射部分的部分,并且可以将外导体的一部分耦合至第二双极发射部分。可以将所述双极发射部分配置为使一个发射部分位于所述电介质接头的近端,并且另一个部分位于所述电介质接头的远端。在单极和双极天线探头中,微波能量一般从所述导体的轴垂直发射。
典型的微波天线具有沿探头的轴延伸的细长内导体,其受到电介质材料的包围,还受到电介质材料周围的外导体的包围,从而使外导体也沿着探头的轴延伸。在提供有效的向外能量辐射或者加热的探头的另一变型中,可以有选择地去除外导体的一个或多个部分。通常将这种类型的构造称为“开槽波导”或“开槽同轴”天线。另一针对微波探头的变型涉及按照均匀的螺旋图案(例如,螺旋线)形成的尖端,以提供实现有效发射的必要构造。可以采用这一变型使能量指向特定的方向,例如,垂直于轴、朝前向(即,朝天线的远端)或其组合。
人们已经开发出了侵入式程序和装置,其中,可以将微波天线探头通过正常的人体孔口直接插入到治疗点,或者可以将其经皮肤插入到治疗点。这样的侵入式程序和装置有可能提供对接受治疗的组织的更好的温度控制。由于使恶性细胞变性所需的温度和使正常细胞受损的温度之间的差异小,因而已知的加热模式和可预测的温度控制是非常重要的,以便使加热局限于所要处理的组织。例如,处于大约41.5℃的阈值温度的高热治疗一般对最恶性的细胞生长没什么作用。但是,在高于大约43℃到45℃的范围的略微升高的温度上,将例行观察到对大部分类型的正常细胞的热损伤。因此,必须极为小心不要在健康组织中超过这些温度。
就组织消融而言,将处于大约500mHz到大约10gHz的范围内的高射频电流施加到目标组织部位上以建立可以具有特定的大小和形状的消融体积。消融体积与天线设计、天线性能、天线阻抗和组织阻抗相关。所述的特定类型的组织消融程序可以指定具体的消融体积,以获得预期的外科结果。作为示例而非限制,脊柱消融程序可能要求较长、较窄的消融体积,而前列腺消融程序可能要求更呈球形的消融体积。
用于执行消融程序的系统和装置利用传感器判断系统是否正确地工作并控制微波消融装置的输出。每一传感器具有电源线、接地线和返回至能量源或发生器的数据线。但是,随着消融装置的演变,传感器的数量也将增加。因而,电源线、接地线和数据线的数量也将增加。现有的发生器可能只有单个电源线、接地线和数据线。因而,可能无法将较新的消融系统和装置配置为与现有的发生器一起使用。

具体实施方式
在下文中将参考附图描述当前公开的用于对来自传感器封装的信号进行多路复用的系统以及采用其的方法的各个方面。在对附图的描述中可以始终采用类似的附图标记表示类似或等同的元件。
这里的公开内容涉及用于执行消融程序的电外科装置和系统。在图1中描绘了用于执行消融程序的电外科系统的示例,该图示出了根据本公开的一个实施例的微波天线组件100。尽管图1示出了微波天线组件,但是本公开不局限于这样的组件。可以将任何能够执行消融程序的电外科装置与文中描述的实施例结合使用。天线组件100可以包括被馈线110(或轴)经由线缆15连接至连接器16的发射部分12,所述连接器可以将组件10进一步连接至功率生成源28,例如,微波或RF电外科发生器。如图所示,组件100是双极微波天线组件,但是其他天线组件,例如单极或漏波天线组件,也可以利用文中阐述的原理。发射部分12的远端发射部分105可以包括终止于尖端123的锥形末端120,从而允许以最低的阻力插入到组织内。但是,应当理解,锥形末端120可以包括其他形状,例如但不限于圆化的、平的、方形的、六边形的、圆锥形的或者任何其他多边形的尖端123。可以将绝缘定标器(puck)130设置到远端发射部分105和近端发射部分140之间。定标器130可以是通过任何适当的工艺由任何适当的弹性体或陶瓷电介质材料形成的。
功率生成源28包括用于控制功率生成源28的适当输入控制(例如,按钮、激励器、开关、触摸屏等)。此外,功率生成源28可以包括一个或多个用于为用户提供各种输出信息(例如,强度设置、治疗完成指示器等)的显示屏。所述控制允许用户调整能量的功率、波形以及取决于预期的组织影响和其他参数的所允许的最高能量水平,从而获得适用于具体的任务的预期波形。天线组件100还可以包括多个相对于功率生成源28的某些输入控制而言可以是冗余的输入控制。将所述输入控制置于天线组件100处允许在消融程序中更简便、快捷地修改能量参数,而无需与功率生成源28进行交互。
图2-6描绘了能够将所有的传感器到发生器的通信都整合到有限数量的信号线上的不同电外科装置,下文将对此予以更为详细的描述。针对各个传感器封装的电源线和接地线将通过从所述发生器到所述装置的单个电源线和公共接地线提供。文中描述的电外科装置适用于能够通过有限数量的模拟或数字传感器线进行读取的发生器。例如,微波消融(MWA)系统可以具有处于装置侧的热电偶传感器,其为无源模拟装置。所述发生器能够通过绞合线对(所述线之一是接地线或者参考线)查看其放大和监测的热电偶电压。对于具有多个传感器封装的装置而言,必须通过这一信号模拟信号线将所有的传感器数据传送至发生器。
为了将所有的传感器输出信号整合到有限数量的线路上,采用处于电外科装置手柄内的多路复用器。所有的传感器输出的模拟或数字信号都被输入到所述多路复用器中。所述多路复用器根据信道选择算法循环历经来自传感器封装的输入信号,并将对应的信号输出到通向发生器的信号线上。
参考图2,电外科系统200包括电外科装置201和发生器202。电外科装置201包括消融天线203,其用于输出辐射,从而使诸如哺乳动物组织的组织消融。通过大功率传输线222将天线203耦合至发生器202。在其他实施例中,可以将发生器202集成到电外科装置201内。发生器202可以具有至少一个用于监测和控制对天线203的功率输出的控制系统。可以针对任何预期的频带对天线203进行优化。可以将天线203以可拆除的方式耦合至电外科装置201和/或发生器202。
电外科装置201包括用于检测一项或多项组织特性的多个传感器204。所述多个传感器204的至少其中之一的非限制性示例可以包括热传感器、电磁场传感器、RF电极阻抗监测器、用户接口电子装置、流体压力传感器、流体流传感器。传感器204可以输出模拟电信号、数字信号或其组合。每一传感器204输出作为模拟电信号或数字信号的指示检测到的组织特性或者检测到的周围环境的特性的信号。所检测到的特性包括但不限于:阻抗、温度、电磁场、组织密度等。
可以将所述多个传感器中的一者或多者包含到一个或多个传感器封装205内。在一个实施例中,传感器封装205可以包括用于调节从传感器输出的信号的一个或多个信号处理电路206。信号处理电路206可以包括用于处理传感器204的输出的各种集成电路和/或分立部件,例如,低噪声放大器、分压器等。在另一实施例中,可以将信号处理电路206配置为按照一种或多种方式修改每一传感器204的输出,所述方式包括但不限于任何类型的模拟或数字修改或转换,例如,放大和/或模数转换。例如,对于输出模拟信号的传感器而言,可以采用模拟信号处理电路通过放大或模数转换对每一传感器204的输出进行调节。
可以采用每一传感器204输出的信号判断传感器是否正常运行,其方式是测量信号的电压并将测得电压与预定电压进行比较。这可以被模型化为阶跃函数,其中,如果满足合适电压,那么系统知道该传感器正在工作,反之亦然。例如,可以如上文所述采用模拟信号处理电路将每一传感器204的输出调节为输出3伏+/-容许误差。如果读到所述电压处于这一范围以外,那么发生器202可以认识到发生了错误并做出相应的响应。在错误情况下,可以向诸如灯或音频装置(未示出)的警报系统发出信号,所述警报系统将通知用户传感器故障或者发生器可以停止向电外科装置201提供能量。

将信号线209配置为最终连接至发生器202,以提供反馈。在信号线209提供的反馈的基础上,发生器202控制其对天线203的能量输出。在诸如图2所示的实施例的实施例中,信号线209可以直接连接至发生器202,而不必经过任何其他级或者可以经过一个或多个电路,从而对信号进行处理。发生器202还提供了电源线224和参考/接地线226,从而向多路复用器207、模拟信号处理电路206和传感器封装205供电。
电外科装置201还可以包括信道选择系统,其包括信道选择线215、计数器217和时钟219。时钟219可以是以预定频率输出信号的晶体振荡器。采用时钟219提供的信号使计数器217递增,计数器217输出所需的二进制表示,以选择输入信道208之一,从而输出与选定输入信道相关的检测到的组织特性。例如,如图2所示,就8比1多路复用器而言,计数器217将输出3位二进制信号。可以采用时钟219和计数器217按照时间循环历经各个输入信道208。
所述信道选择系统可以包括用于自动选择一个或多个信道的信道选择算法。所述算法可以具有选择功能,从而使所述多路复用器按照选定变量选择信道,所述变量包括但不限于时间、电外科装置的相对位置、文中描述的任何预期组织特性、温度、阻抗、EM场或其任何组合。所述算法包括计算选择函数、选择信道以及沿信号线输出来自选定信道的信号。

之后,多路复用器207采用信道选择系统和/或信道选择算法选择对应于预期组织特性的输入信道208,并在信号线309上输出指示预期组织特性的模拟检测组织特性信号。信号线309可以将所述模拟信号直接提供给发生器302,或者可以在电外科装置301向发生器302输出信号之前采用模数(A/D)转换器311将所述模拟信号转换为数字信号。
