Abstract
一种电手术器械,用于在导电液体介质存在下的组织处置,该器械包括器械轴柄(32),和在器械轴柄一端的组织处置电极(31),所述组织处置电极被构成确定多个囊泡,用于收集导电液体。另外,组织处置电极(81)由导电材料(81a)制成并涂有电阻惰性材料(81b),该材料可有效地增大所述组织处置电极内的局部功率密度。
Description
本发明涉及一种电手术器械,用于在导电液体介质情况下的组织处置,还涉及包含这种器械的电手术设备,以及该种器械中所用的电极单元。
内窥镜电外科通常用于治疗体腔内的组织,而且一般是在有膨胀作用介质的情况下进行的。当膨胀介质为液体时,通常将之称为水下电外科,这个术语意味着于电外科时在手术部位处采用具有一个或多个被浸在液体内之处理电极的电手术器械使活体组织得到治疗。在较大潜在体积的膨胀性体腔内实行内窥镜外科时,其中液体介质是不适用的,有如通常在腹腔窥镜外科或胃肠外科中的情况那样,通常都采用气体介质。
水下外科通常是采用内窥镜技术实施的,其中内窥镜本身可设有一个导管(通常称为工作通路),用为电极的通路。另外,可将内窥镜特别配备成(如前列腺切除器)包含有安装电极的装置,或者可在关于内窥镜成一个角度的情况下借助一分开入口的装置将所述电极引入体腔内一一通常被称为三角形技术。可由外科学专业对这些技术上的变型再予细分,这些技术的一种或它种都具有对特定体腔提供入口通路的特别优点。在可通过自然人体开口进入体腔的情况下,一般采用具有多个必备的操作通路的内窥镜,那些被称为前列腺切除器的内窥镜,一一如通向子宫内膜腔的子宫颈管,或者通向前列腺和膀胱的尿道。为用于子宫内膜腔所特别设计的内窥镜被称为子宫镜,为用于尿道而设计的内窥镜包括膀胱镜、尿道镜和前列腺切除器。前列腺的经尿道切除手术过程或蒸汽疗法分别被称为TURP和EVAP。当没有可供内窥镜通过的自然人体开口时,通常就采用所说的三角形技术。三角形技术通常被用于比如膝和肩等关节腔的水下内窥镜外科过程中。这些过程中所用的内窥镜通常被称为关节镜。
通常采用单极器械或双极器械实行电外科。采用单极电外科,将一有效电极用于手术区,同时将一导体回流板紧固于患者的皮肤上。采用这种布置,电流从有效电极通过患者的组织流到外部回流板。由于患者相当于电路的一大部分,输入功率的值就必须比较大(通常为150到250瓦),以补偿患者组织阻碍电流的限制,而且,在水下电外科的情况下,由于液体介质因血液或其它体液的存在而表现为不完全的导电之故,要消耗功率。由于所述回流板处存在组织发热的缘故,使得采用单极布置而使用较大的功率还是危险的,即可能造成严重的皮肤灼伤。在体腔的进入点处还存在器械与患者组织间电容性耦接的风险。
采用双极电外科,将一对电极(有效电极和回流电极)同时用于组织的操作部位。由于两个电极的相对接近,使射频的电流被限制于两电极之间的区域,所以从安全的观点看,这种布置有优点。可是,作用深度却直接与二电极间的距离有关,并且在使用所需的极小电极的情况下,电极间的间隔变得非常小,因而就限制了对组织的效果,也限制了输出的功率。进一步分开电极间的间隔常会遮蔽操作部位的观察,而且为保证两个电极与组织的正确接触,还需要改变手术技术。
有许多关于双极探针基本设计变型。例如美国专利说明书US4,706,667描述了一种基本设计,即就切割目的而言,回流电极与有效电极接触面积之比大于7∶1而小于20∶1。这个作用范围只与截割电极的外形有关。当把双极器械用于干燥法或血凝固时,可使所述二电极的接触面积比降低到近于1∶1,以避免组织与各电极间接触处存在的不同电应力状态。
可以利用诸如普通食盐水类导电溶液湿润所述组织而使所述回流电极与组织间的电接合得到保证。随着通过所述组织实现二电极间的电路,保证了使手术效果被限制于针电极或有效电极处。采用这种设计的明显限制之一是,必须使所述的针被完全埋入所述组织中,以使回流电极实现所述电路。另一个问题是定向问题,即使是操作角度相对组织表面理想的垂直接触有较小改变,也会改变所述接触面积之比,使在与回流电极接触的组织中发生手术影响。
腔体膨胀提供了为改善目视观察而进到操作部位的空间,以改善目视观察和得以操作器械。在小体积的体腔内,需在较高压强下扩张腔体,用液体代替气体更为常用,这是由于光学特性更好些,而且也因为它将血液冲洗得远离操作的部位。
为消除电导的下降而采用不导电液体(比如1.5%的甘氨酸)作为冲洗液或作为膨胀介质,已使现有的水下电外科得以实现。在等渗透压浓度下使用甘氨酸,以避免在存在血管内的吸收作用情况下血液中的渗透变化。在操作过程中,可使静脉被切断,由于液体融合渗入到循环中去,这可能引起血清钠的稀释,而导致被称为水中毒的状态。
本申请人发现,在水下内窥镜电外科中,可以采用导电的液体介质,如普通食盐水来代替不导电的无电解质的溶液。在不考虑电外科,或者采用非电组织效应,如激光治疗的情况下,普通食盐水是水下内窥镜外科中优选的膨胀介质。虽然普通食盐水(0.9%w/v,150mmol/l)具有比大部分人体组织稍大些的导电性,但它的优点在于,通过吸收或从操作部位外渗排代而产生很小的生理效应,并可使不导电的无电解质溶液的所谓水中毒效应得以避免。
本申请人发展了使用导电液体或气体介质的适用于水下电外科的双极器械。这种用于在导电液体介质情况下组织处理的电手术器械包括:具有手柄和器械轴柄的器械主体,以及在所述轴柄一端的电极组件。所述电极组件包括一个露出于器械最远端的组织处置电极,和一个回流电极,它与所述组织处置电极电绝缘并有与一靠近所述组织处置电极露出端相隔离的液体接触面。使用这种器械时,将组织处置电极用到待处理的组织处,另一方面,被置于靠近组织处置电极露出端有一段距离的回流电极通常与所述组织相隔离,它用于通过所述组织及液体介质从组织处置电极完成电手术电流回路。未决国际专利申请PCT/GB96/01473的说明书中描述了这种电手术器械,它的内容被列为本申请的参考文献。
这种与导电液体介质相结合之器械的电极结构极大地避免了单极或双极电外科方面的问题。特别是,输入功率的水平大大低于采用单极结构一般所需的功率(通常为100瓦)。此外,由于其电极间的间隔较大,与常规的双极结构相比,使作用的深度得到改善。
图1示出这种类型的器械用于通过蒸汽疗法除去组织。该器械的电极组件12包括伸出于器械远端的组织处置(有效)电极14和一个回流电极18,后者由一绝缘套管16与所述组织处置电极电的露出端分开。对该电极组件供能,以便在组织处置电极14处形成足够高的能量密度,用以使组织22汽化,并形成围绕着有效尖端的蒸汽囊泡24。蒸汽囊泡24的形成造成接触阻抗增大到大约10倍,输出电压随之理所当然地也增加。在蒸汽囊泡24中形成电弧26,以完成到回流电极18的电路。与蒸汽囊泡24接触的组织22将会为完成所述电路提供最小电阻路径。组织22越接近电极14,就会有更多的能量集中在该组织处,达到随着细胞被电弧26击穿,使它们被分解的程度,这是因为通过导电液体(在这种情况下为盐水)的回流路径被蒸汽囊泡24的高阻抗势垒所阻断。食盐水溶液还起使汽化作用的固态产物溶解的作用。
为达到汽化所需的能量阈值是这类器械的重要参数,本发明的目的在于提供具有得到改善的蒸汽疗法能量阈值特性的双极电手术器械。
因而,按照第一方面,本发明提供一种电手术器械,用于在导电液体介质情况下的组织处置,所述器械包括一个器械轴柄,和位于该轴柄一端的组织处置电极,使所述组织处置电极构造成确定多个囊泡,用以捕集导电液体和蒸汽。
使用时,所述组织处置电极捕集导电液体,于是,比起这种情况下用其它方法来,这种被捕集的液体吸收更多的用以转换成蒸汽的电能。这导致为在组织处置电极蒸发的能量阈值的降低。
随着组织处置电极的不平整(凹穴)处所捕集的导电液体变得越热,它逐渐吸收越多的能量,并且不由周围环境的液体补充。当所述液体达到沸点时,在电极表面上开始形成蒸汽囊(泡)。这些蒸汽囊使导电液体与电极区域绝缘,于是,能量就被集中于未被包围在蒸汽中的电极区域。随之,邻近这些被暴露区域的液体迅速达到汽化点,使整个组织处置电极被包敷于蒸汽中。蒸汽被有效电极的不规则形状处所截留,以致,若在使用过程中电极区域被露出于液体介质,则所述蒸汽囊便迅速形成,随之最小的功率消耗于周围的液体。这导致在使用过程中引起和维持蒸汽囊所需能量阈值的降低。

下面所描述的每一种电极单元指的是采用比如普通食盐水的导电液体介质,而且每一种单元都具有双极结构,导电介质作为要处置的组织与另一个电极之间的导体,以下将该电极称为回流电极。一个电极被直接加给组织,并在下面被称为组织处置(有效)电极。
参照各图,其中图2表示包括具有输出插孔2之发生器1的电手术设备,所述插孔经接线电缆4对手柄3形的器械提供射频(RF)输出。可由手柄3经电缆形的控制接线4或者借助脚踏开关装置5实现发生器1的启动,如图中所示,利用脚踏开关接线电缆6使脚踏开关5被分开连到发生器1后面。在所示的实施例中,脚踏开关装置5有两个脚踏开关5a和5b,分别用于选择发生器1的干燥方式和蒸汽疗法方式。发生器的前面板上有按钮7a和7b,分别用于设定干燥及蒸发功率的大小,并由显示器8指示之。设置按钮9a作为变换装置,用以在干燥方式和蒸汽疗法方式之间选择。手柄3按装一个可卸下的电极单元E,比如下面将要描述的电极单元E1到E7。
图3表示第一种形式电极单元E1的远端,用于可拆卸地紧固到电手术器械的手柄3上,该电极单元E1由在其远端的电极组件形成,所述电极组件包括中央组织处置(有效)电极31和管形回流电极32。有效电极31由铰合的金属如钨、贵金属如铂,或者诸如铂/铱、铂/钴或铂/钨等铂的合金制成,回流电极32由不锈钢管制成。回流电极32由一聚酰亚胺绝缘外壳33所完全包封。回流电极32沿所述电手术器械的整个长度延伸,构成器械的轴柄。因此,使回流电极32维持较低的温度,这是由于导热性沿其纵向之故。
由射频(RF)发生器1为电极31和32提供电流,回流电极32直接与该发生器相连,而有效电极31经铜导线34与之相连。所述发生器可以是有如未决欧洲专利申请EP96304558.8的说明书中所述者。借助陶瓷绝缘体/隔离器35使有效电极31保持在回流电极32内的中央。绝缘体/隔离器35一般具有圆柱形部分35a,它围绕着有效电极31与回流电极32之间的接合处以及此二部件的邻接区域,还有4个径向伸展的等间隔的翼片35b,它们与回流电极32的内部周壁接触,以固定该绝缘体/隔离器,并因此而使有效电极31保持在回流电极内的中央。
由比如PTFE绝缘材料制成的管子36是绝缘体/隔离器35的圆柱形部分35a近端周围的摩擦配合,它基本上沿着所述器械的整个长度伸展。管子36与回流电极32一起限定轴向的食盐水供给通道37,管子36的内部限定食盐水回流通道38。使用时,在重力作用下(无需泵)将食盐水供给通道37,食盐水借助空吸经通道38和绝缘体/隔离器35的圆柱形部分35a中的小孔(未示出)移动。
最好由诸如活动轮叶泵或隔膜泵等低噪声泵(未示出)代替使用高速叶轮实现空吸。当管道系统导致这种泵将会周期性地含有少量盐水时,需要高真空(至少为500mBar)。不过,所要移动的气体或液体的量是比较小的,这就容许使用活动轮叶泵或隔膜泵,尽管也可以使用大容积压缩泵。
为避免需要使泵不起作用,使所述泵借助一个易于处理的、与10μmPTFE过滤器结合的液体收集器(未示出)工作。该过滤器既能防止被排出的液体和气体散粒被从泵中抽出,又能避免沾污它的工作环境和周围环境。
上述器械准备被用于敞口的充有空气或气体的环境、体液中,或者通过在器械尖端周围形成导电液体环境而插入组织,而且还可将其布置成能够在器械的远端形成局部的食盐水环境。因此,可将这种器械用于腹腔镜的应用。使用时,经通道37将食盐水送入有效电极31,带有食盐水的导电介质在被处置的组织与回流电极32之间起导电通路的作用。改变发生器1的输出,可使所述器械被用于经蒸汽疗法而除去组织,用于割除或用于干燥组织。在每一种情况下,随着食盐水与有效电极31接触,使它受热,直至它达到一个与发生器1功率输出及食盐水的流量有关的平衡温度。平衡时,随着新的食盐水经通道37被送到有效电极31,所述轴柄的外部温度被保持在与食盐水周围温度相同的温度。当绝缘外壳33完全覆盖回流电极32的外表面时,得以避免回流电极与组织间的偶然接触。
采用低食盐水流量的优点在于,可使食盐水的温度达到沸点。但是,当存在连续的食盐水流时,就在食盐水中从回流电极32到有效电极31存在温度梯度。这种温度梯度是重要的,随着较热的食盐水邻近有效电极31,就降低了为实现蒸汽疗法所需的能量阈值。虽然可以根据输入功率计算所需的流量,但保持最佳能量密度的发生器1的适应性意味着所述流量是非临界的。例如,如果发生器1被认为是100w,则最大流量理论上可如下计算:
流量=功率/比热容
=100/4.2×75cc/s
=0.32cc/s
=19cc/min这是假设食盐水的初始温度为25℃,热容量为4200J/kg/℃。
虽然在蒸汽疗法过程中,食盐水进入蒸汽状态,但这种蒸汽仅在有效电极31周围是稳定的。因此,借助汽化潜热所吸收的能量可被忽略不计,正像这种能量是由新到的食盐水所补充的一样。
另一个重要的因素是,由于食盐水的循环路径非常短,可将电流看作是在沿着若干不同的路径流过,所以,没有相同的能量密度。因此,由于盐水介质内能量密度的不相等,汽化作用可发生在高于所算得的最大流量情况下。不过,沿着有效电极31的长度存在的蒸汽量将与流量有关。
随着由有效电极31使食盐水变热,对组织的潜在损伤是引起热坏死。因此,重要的在于,在进入与邻近应用部位的组织接触之前,要由患者回收并耗尽全部热食盐水。正因为这个原因,就要有从有效电极31到排放容器(未示出)的抽吸。不过,通过保证存在过量抽吸,则除经盐水回流通道38以外,不可能有食盐水从有效电极31的范围漏泄。横向越过外面轴柄的所有食盐水都会从流路上消失,以致不会发热。所以,优先要考虑的事就是保证取走热的食盐水。当有效电极31附近的热梯度为最大时,这是最合适的盐水消耗位置。正因为这个原因,通过绝缘体/隔离器35的圆柱形部分35a使食盐水得以被消耗。
在判定盐水排放位置中的另一个重要的考虑是排放路径阻塞的潜在可能。这可能发生在以比如释放出小的组织微粒的方式切除组织或汽化组织的情况下,这些微粒可能容易阻塞所述的排放。因此,要将排放的位置选在有效电极31上能量密度最高的位置处。这种措施可保证接近排放置的组织立刻被汽化到溶液中,从而避免了阻塞的潜在可能。
在通过蒸汽疗法除去组织过程中保证高度抽吸的另一个重要的优点在于,还可抽空所有尚未被食盐水吸收的烟尘。这是重要的,因为烟尘能够传送有生命活力的生物微粒,而且这能够导致感染。
如上所述,所述汽化的能量阈值并非很好确定。如果使所述器械在静态的导电介质中工作,则通过电阻转换点将能很好地确定所述汽化的阈值,所述转换点是指作为在有效电极31周围形成蒸汽囊泡的结果,电极的电阻突然升高的点。所述阈值通常与食盐水的逸散机制有关。在静态介质中,所述逸散机制由食盐水中的运流电流起主要作用。在这种情况下,由输入到电极有效区域的功率确定汽化的能量阈值,所述电极有效区域是食盐水过分逸散的区域。但如上述,在本实施例中,有效电极31周围的食盐水是连续被补充的。如果不是这样,则逸散机制只能是汽化潜热,而且盐水会快速汽化。通过提供流动,可提高所述阈值能量的水平。然而,所述阈值能量的水平与有效电极31极末端区域的盐水补充流量有关。通过变换有效电极31表面的最后加工,可以改变此边界层处的所述补充流量。例如,如果有效电极31具有光滑的表面,则可快速补充食盐水,同时可得到快的流速。但是,当有效电极31具有凹凸不平的表面加工时,将使这种凹凸不平表面内蒸汽囊的更新速率减小。于是,凹凸不平表面阻挡盐水(或者至少是延迟所述的更新)和蒸汽,从而在被补充之前能吸收更多的能量。换句话说,利用凹凸不平的有效电极表面可降低所述能量阈值。当实质上降低电极功率的需要而不有害地影响组织的性能时,这是极为需要的特点。还因将有效电极31构造成具有毛细作用,而使所述阈值能量降低。因此,即使在汽化状态下,也会使有效电极31周期性地被浸湿。通过毛细作用,使整个有效电极31因得到这种浸湿而是湿润的,存在一个使所述周期性浸湿减至极小的连续的蒸汽源,并因此而进一步降低能耗。
回流电极32有一个对对流电流没有阻碍作用的光滑的抛光表面。因此,回流电极32有一个经常变化的被快速替换的盐水边界层,并且该回流电极具有较高的能量阈值。另外,回流电极32形成食盐水供给通道37的一个边界面,以致沿着该回流电极存在食盐水的紊流。这使得所述边界层中的替换是非常快速的,而电极32自身也为这种流动所冷却。回流电极32能量阈值的有效增加意味着,在回流电极处可以从不发生汽化作用。当然,使回流电极32的能量阈值按这种方式增大,就使得它是明显地超过最大的可以得到的功率。这就保证了即使回流电极32部分被遮蔽,或者食盐水流受阻,在回流电极32处也将从不能达到汽化作用的能量阈值。由于在回流电极32处不能达到汽化作用的能量阈值,就不存在因回流电极使组织受到汽化的风险。因此,使间接的组织损伤得以避免。此外,由于盐水排放通道38位于回流电极32内,所以有效地除去最热的盐水,从而排除了因一缕缕离开有效电极31的热盐水的喷出而使组织伤害。
通过改变发生器1的输出,还可将电极单元E1用于干燥(凝固)。在这种情况下,控制发生器1,使得在有效电极31的表面上形成小的蒸汽囊(bubble),但没有足够的蒸汽被产生,去提供围绕所述电极有效尖端的蒸汽囊,对于通过汽化作用而除去组织来说,这种蒸汽囊是不可少的。
按这样一种方式使发生器1受到控制,即使得它分别有用于组织干燥和用于通过蒸汽疗法除去组织的输出范围。前者的范围在从150v至200v,后者的范围在从250v至600v,这些电压均为峰值电压。在蒸汽疗法方式中,以这样的方式控制发生器1,使之防止有效电极31过热。这需要一旦已经产生蒸汽囊(泡)(pocket),就需要降低发生器1的输出电压。在我们的未决欧洲专利申请EP96304588.8的说明书中,以更加详细的方式描述了发生器1及其控制方式。
用这种电极凝固是大大优于任何一种双极电极的。理由有两方面。首先所述凝固的机制不仅在于组织内的电流,而且还由于热的食盐水。其次,在正常情况下,给所述组织提供电功率的最弱环节是电极的分界面,因为这里是能量密度最高的位置,于是就给出一个功率限制。如果希图过高的功率水平,则在该分界面处的组织就会快速地干燥,远快于形成其余电路的较大截面积的组织。如果选择低功率,则该分界面可由与汽化作用不同的机制耗散温度的升高。因此,越长地保持该分界面不受损伤,就能实现越深的效果。在本实施例中,借助于所述食盐水,使得这种电的分界面是非常强的,而且不可能完全干燥靶组织。因此,可长时间地在较高速率下供给能量,而作用深度与时间和电能有关。
汽化作用的阈值控制是这种多功能有效电极的一个重要方面,对于干燥来说,有效电极的面积是最大的,而通过在有效电极的间隙内保持蒸汽囊和热的食盐水,则可实现蒸汽疗法或切割功能。
如上所述,双极电手术器械设计的基本特点在于回流电极的接触面积与有效电极的接触面积之比。对于蒸汽疗法而言,这个比率应该较高,而对于干燥而言,这个比率应该较低。因此,对于多功能电极来说,应该找到一种平衡。电极单元E1通过使所述比率最小,以保证有效的干燥,同时通过控制汽化作用的阈值,以保证有效的蒸汽疗法而达到这种平衡。
图4表示第二种形式电极单元E2的电极组件。电极单元E2有一轴柄(未示出),用以将该单元可拆卸地连接到电手术器械的手柄3上。所述电极组件位于该轴柄的远端,而在该轴柄的另一端设有一装置(未示出),用以以机械方式和电的方式将所述电极组件与手柄3连到一起。
所述电极组件包括中央组织处置(有效)电极41,它露出于所述器械的最远端。有效电极41由金属如钨、贵金属如铂,或者诸如铂/钴、铂/铱或铂/钨等铂合金的铰合的合股线制成。通过一金属导线(未示出)使有效电极41与射频发生器电连接。绝缘套管42(Sleeve)围绕着有效电极41和内部的导线,该绝缘套管的远端被露出,接近电极41的露出部分。套管42由陶瓷材料、硅橡胶或玻璃制成。回流电极43围绕着绝缘套管42,该回流电极呈不锈钢管形式。回流电极43由所述器械轴柄的远端部分构成,并与所述射频发生器电连接。外部绝缘的聚酰胺绝缘外壳(未示出)包围邻近回流电极43的轴柄部分。
图4的电极单元E2用于通过在由比如食盐水类导电液体形成的膨胀介质内的汽化作用除去组织。在这种情况下,为达到汽化所需的能量阈值与有效电极41的功率消耗能力和围绕该电极的流动特性有关。当把该电极组件浸入食盐水中时,功率消耗是通过电到热的转换。受热的食盐水像一缕羽状物那样,通过对流作用从有效电极41升起。在这种情况下,汽化的能量阈值与从有效电极对流的最大流量有关。
最大的功率密度存在于有效电极41的表面边界处。功率密度以与1/d2成比例的比率减小,这里的d是离开有效电极41的距离。所以正是有效电极41的表面处的食盐水确定着所述的能量阈值。由于在这个位置的对流和传导损失,盐水的替换比率确定所述的能量阈值。一旦这个边界层汽化,则电极41就变成稳定在以较低的功率水平汽化的状态。
有效电极41的不规则表面会滞集食盐水,以致在被替换之前吸收较多的能量。高度抛光的有效电极将有一稳定地改变的盐水边界层,这是由于对流“冲洗”它的表面的缘故。在这种情况下,所述边界层会以较高的速率被更换,致使有一较高的能量阈值。然而,有效电极41的不规则表面造成食盐水(和蒸汽)的滞集,使所述的盐水边界层按较低的速率改变。于是,有效电极41的不规则表面确定大量的峰和谷。在峰的边界层处的食盐水将快速地被对流所替换。但谷内食盐水的对流将受到阻碍。因此,谷内的食盐水将不会那样快速地被替换,以致在其被替换之前将吸收较多的能量。换句话说,利用有效电极41的不规则表面,使所述能量阈值下降。恰如图2的实施例那样,这是所希望的电极功率需要的实质性下降,而不有害地影响组织的性能。还因为将有效电极41构造成具有毛细作用,而使所述能量阈值进一步下降。于是,即使在汽化状态下,也会使有效电极41周期性地被浸湿。通过毛细作用,使整个有效电极41因得到这种浸湿而是湿润的,存在一个使所述周期性浸湿减至极小的连续的蒸汽源,并因此而进一步降低能耗。
在电极单元E2和E4中,合股线被表示为松散地铰合,以致相邻的合股线或者彼此间隔地或者并非整个地互相邻接着。这样的结构在电极上留下一系列开口,所述电极连到电极结构内的中央轴腔,所述电极结构沿电极的纵轴安置。为避免电极在其远端磨损,可使所述合股线的远端通过比如焊接或其它融合方法连在一起。
参照图5,在图4实施例的一种变型中,另一种电极单元E3具有多条导电的合股线,它们互相铰合,或者换句话说彼此紧密地交织,使得相邻的合股线彼此紧密地相压,造成该铰合结构内沿电极纵轴安置的所有空腔都是小的,或者不存在空腔。在这个实施例中,实质上是所有用于滞集导电液体的蒸汽囊都位于所述电极的外表面,在相邻合股线之间结合处内,或者沿着这些结合处。合股线的首选材料是铂和钨的合金。紧密卷绕的结构给出比图4所示电极单元E2更为坚固的结构。也使各合股线在电极的最远端处被焊在一起。
作为所述各图中未予示出的另一种可供选择的电极结构,可使中央组织接触(有效)电极41由单个的表面形成有螺脊的长导电材料造成,所述螺脊或者通过模铸、机械加工形成,或者通过绕其纵轴铰合材料片(最好是非圆形截面的),造成绕其外表面的螺脊。如前所述,这些螺脊之间形成蒸汽囊。可以通过铰合所述材料实现由非圆形截面的长材料形成螺脊,以致所述螺脊以与当把弹性带材绕其自身的轴铰合而形成螺脊时同样的方式被形成。
还可将上述图4的另一种铰合及交织的电极结构用于图3的实施例中。
图6至图8表示图4和5的电极单元E2和E3的变型E4到E6,因而将把相同的参考标号用于同样的部件,而且将只详细描述那些改型的部分。于是,图6的电极单元E4包括呈螺线圈形状的有效电极51,该有效电极由钨、诸如铂等贵金属,或者诸如铂/铱、铂/钴或铂/钨等铂的合金制成。使用时,食盐水被滞集在螺线圈的相邻回绕之间,致使这里也有盐水边界层以较低的速率在改变,从而保证有效电极51具有较低的能量阈值。有效电极51具有附带的优点,即食盐水被收集在螺线圈本身内,从而导致进一步减少了边界层食盐水的替换,而且顺带地进一步减低了所述能量阈值。
图7表示电极单元E5具有呈刷形的有效电极61,所述刷形电极由钨、诸如铂等贵金属,或者诸如铂/铱、铂/钴或铂/钨等铂的合金制成。使用时,食盐水被滞集在细丝的合股线内,而且也导致减少了边界层食盐水的替换,而且减低了所述能量阈值。刷形电极61的细丝还提供进一步减低所述能量阈值的毛细作用。
图8实施例的电极单元E6与图6的情况类似,具有呈螺线圈形状的有效电极51,螺线圈由钨、诸如铂等贵金属,或者诸如铂/铱、铂/钴或铂/钨等铂的合金制成。不过,在本实施例中,绝缘套管42由一个构成罩盖的拱形延伸部42a形成。罩盖42a的内表面紧密地覆盖螺线圈电极51的回绕,盖住其周缘的一半。于是,罩盖42a阻碍所述的对流,从而增大了电极组件滞集食盐水的能力,并导致进一步减低所述能量阈值。这种电极组件得益于次生机制。于是,当处于汽化状态时,组织的破坏生成气态产物。罩盖42a滞集这些气态产物,并借助这些气态产物的绝缘性质隔绝了传导。
图9表示又一种形式的电极单元E7,它有呈滚球形的有效电极71。滚球电极71由不锈钢制成,可转动地被支撑在导电材料,如铜制成的支架72上。普通半球形的罩盖73被安装在支架72上,以便紧密地围住滚球电极71大约一半的面积。罩盖73由诸如陶瓷材料、硅橡胶或玻璃等绝缘材料制成。由不锈钢制成的回流电极74安装于罩盖73的侧面,远离滚球电极71。这里罩盖73也是将食盐水收集于它的内表面与滚球电极71的外表面之间,使有效电极的能量阈值得以被降低。罩盖73还滞集汽化产物,以减小较大的有效电极71的有效尺寸。此外,通过隔断通过食盐水的直接回流路径,可有效地增大回流电极与有效电极的面积比率。这一特点减少了为支持汽化所需功率的量,并且还能采用比其它方法所能用的大得多的有效电极71。罩盖73的另一优点是,它保持有效电极71的最近区域的介质不受其它方法中会由盐水流所产生的扰动。
图10表示再一种形式的电极单元E8,它有一个由针状电极81a构成的有效电极81,该针状电极由涂有导电陶瓷材料81b的钨、诸如铂等贵金属,或者诸如铂/铱、铂/钴或铂/钨等铂的合金制成。涂层81b通过增大有效电极81内的局部功率密度,增大了盐水边界层处的功率消耗。这引起电极81与所述食盐水间的层间阻抗的加大。功率消耗的这种增大导致电极1能量阈值的降低。这种降低有效电极81量阈值的方法,对于因某些操作之需所加给的限制而使有效电极必须非常小的情况是特别有用的。显然,可给电极81a涂以任何电阻惰性高的材料,如高阻金属涂层,它能耐受与组织的汽化相关连而升高的温度。另外,可以通过给电极81a喷一层多孔的绝缘材料,如陶瓷材料,而使电极81a的局部功率密度增大,所述喷射在导电表面上产生绝缘斑点。
图4至10的每个实施例中的回流电极都具有光滑的抛光表面,不阻碍对流。因此,当采用图2的实施例时,这些回流电极中的每一个,都有较高的汽化能量阈值,因而不存在被回流电极汽化的组织的风险,也不存在间接的组织损伤的风险。这些实施例中每一个的电极组件都可被置于靠近内窥镜的盐水供给部分,致使输送将流过整个回流电极,而沿着该电极给出盐水紊流。这将引起回流电极处的边界层替换是非常快速的,这进一步增大了该回流电极的能量阈值。
如上所述,各多功能电极单元需要汽化阈值的控制,以及最小的回流电极与有效电极的接触面积比率。这种最小的比率取决于四个重要的准则,即:
1.靶组织的固有阻抗;
2.体腔的容积;
3.有效电极的构造;
4.射频发生器的最大输出功率。
有效电极的构造显著地影响这个比率,可采用对于给定长度为最低比率的圆柱形式,而其它因素与电极保持蒸汽囊的能力有关。刷形电极的各细丝保持蒸汽囊,这有助于保持汽化的条件。于是,这类电极的所述比率可以是各多功能电极中最低的,而且当与采用高阻抗应用于组织相结合时,这个比率小于对于干燥功能的情况,也即在1∶1到2∶1范围内。然而,采用实心电极形式,对于给定的电极尺寸而言,在较小比率下汽化条件的转换和保持需要较高的功率水平(在直径为1.5mm情况下,大于150w)。于是,对于这些形式而言,必需将所述比率提高2∶1到3∶1范围内。采用各种槽或切口的改变,或者通过用卷绕的金属线制成类似的形式而改变所述外表面,有助于刷形电极蒸汽囊的保持,而促进汽化作用的实行,从而使所述比率得以减小。
关节内窥镜的电极可以其短(100-140mm)、坚固、和具有可达4mm工作直径为特征。可以采用三角形技术,通过一个刺穿切口将其引入关节腔(有或没有套管)。它通常以在关节内窥镜图样的9点钟和3点钟的位置间移动而动作。于是,要处理的组织,一般相对于所述电极轴接近一个小的作业角度。因此,所述有效电极需要包括端部起作用到侧向起作用特点的作用范围。在某些情况下,希望是端部起作用,特别是,当端部起作用是非常难于达到使用切除装置时,所述切除装置中的转动中心代表所需的应用点。待处置的组织(如半月板软骨)一般是致密的,而且电阻抗也较高,这种组织具有代表常见的需要手术的损伤部位的软骨的自由的边缘。电极单元E1、E2、E3、E4、E5和E8是适用于关节内窥镜的端部起作用电极单元。
绝缘体材料的延伸部或侧向起作用结构有助于连接和防止存在于相邻结构一通常是股骨和胫骨的接合面一中的不希望有的影响。另外,延伸电极或侧向起作用电极形式(图8和9)形式还有助于保持蒸汽囊,并通过盐水流从内窥镜冲洗而避免紧靠有效电极的盐水冷却。
关节腔内热膨胀液体的风险主要发生在为达到汽化阈值的功率使用期间。一旦已达到所述阈值,功率的需要通常会下降30-50%。降低所述的比率,增大了为达到所述阈值的功率需求,以致尽管靶组织的阻抗较高,也不希望使所述比率降到能够支持汽化的最低值。汽化阈值控制的性能保持了电极间隙中的蒸汽囊和热食盐水,并使所述绝缘体成形为减少冲洗流的影响,从而有助于减少为达到汽化所需的能量,并因此而减小了不希望有的受热风险。
作为举例,图6的螺线圈金属线形式的电极能捕俘汽化产物,就像图8的电极(具有遮蔽有效电极之非接触区的绝缘体附加性能的侧向起作用形式)那样。绝缘体的附加遮蔽性能可使为达到汽化阈值所需的能量减半。
在使用关节内窥镜时,主要的功能通常包括致密的无血管组织的快速分离。对于给定尺寸的电极来说,通过汽化阈值的控制以及加大射频发生器1的输出电压的结合,可以增大被除去组织的体积。图11表示图8刷形电极的示意图,其中汽化阈值被超过,在每个细丝周围形成以参考标号P代表的蒸汽囊。当用于组织时,特别是用于坚实而致密的组织,如包含半月板软骨的组织,结果将是与每条细丝相应的组织内一系列槽穴的汽化。加大射频发生器的输出电压将增大每条细丝周围蒸汽囊的尺寸,因为留置物将达到图12所示的程度,这时,它们合并,形成一个以参考标号P′代表的连接的蒸汽囊,致使可能已由其它方法通过各细丝之间的组织也被汽化。
我们的未决欧洲专利申请EP 96304558.8揭示了干燥输出功能和汽化输出功能之间区别。它还揭示了通过在这些输出状态之间的不断改变可得到混合功能。汽化阈值控制在这些情况下是特别有利的,如干燥输出相所产生的热盐水被保持在有效电极附近,使得在汽化过程中快速地超过所述汽化阈值。作为在使肌肉与骨骼附着物分开情况下,比如在肩关节的肩峰整复,或者使病变组织与诸如滑膜类血管组分分离中实行同时干燥的方法,这是有用的。
图9的实施例特别用于前列腺切除器,以实现前列腺的电手术蒸汽疗法(EVAP)。这种特别的构造包括滚柱(圆柱形)有效电极71,通常是直径2.4-3mm,宽3-4mm。很明显,可按轴向分离布置的方式将回流电极74安装在轴柄72上。不过,在这种情况下,有效电极71的尺寸和整个表面面积暴露到导电介质中,以及在所述电极上方冲洗流的冷却作用都将需要非常高的功率,以达到汽化阈值。
应能理解,可使电极71被作成凹凸不平的槽穴或棱脊,以便进一步降低所述汽化阈值。类似地,可用图8的侧向起作用有效电极(它相对于前列腺切除器的轴按轴向方式或横向方式安装)代替图9的电极组件。在这种情况下,所述有效电极将不具有机械滚动的功能。
这种器械还可被用于软组织肿瘤的电手术蒸发汽化,如前列腺瘤的电手术蒸汽疗法,而无需在导电液体介质中使用一分散回流板。前列腺切除器,还可用于子宫腔内的纤维瘤。
上面所述的电手术器械还有冲洗电极的应用。于是,上述每一种应用,都用一种方法形成局部食盐水工作介质作为手端来完成轴向分开的有效电极和回流电极的电路循环,以便在无论是自然源亦或外科提供的充有气体或空气的体腔内,或者在人体组织表面实现组织的蒸汽疗法、切割或干燥。
具体地说,每一种这样的器械都采用一种除去组织的方法,通过蒸汽疗法,其中通过直达或者邻近有效电极组件的抽吸,将汽化产物被从应用的部位抽出。还可通过从天然体腔,如窦、鼻腔及口咽内汽化而除去病变组织。类似地,还可通过在气体膨胀条件下从腹腔中汽化而除去病变组织。
这种器械还可被用于在待处置的组织深深地处于组织表面内的间隙部位创造手术入口。
