向体内器械传递电力的系统和方法
相关申请的交叉引用
本申请要求于2010年3月5日提交的、序列号为61/310,786的美国临时申请的利益和优先权,将所述申请的全部内容通过引用并入到此。
技术领域
本公开涉及一种对待手术的人体执行微创型手术的手术自动器械,更确切地,涉及一种向所述手术自动器械传递电力的系统和方法。
背景技术
微创型手术操作通常采用体腔内的小切口来使包括镊子、腹腔镜、解剖刀、剪刀等的各种手术器械进入。通常情况下,在特殊的手术操作中,手术医生需要借助一些手术手(诸如一些腹腔镜器械和摄像机夹持支架)来保持这些器械。近年来,随着自动辅助微创手术(MIS)的引入,世界范围内的医院都已经投入大量资金以在其各自的设施内获得这一最新的技术。
因此,当执行手术操作时使用MIS是公知的。当执行这种手术时,经由一些(通常为3至5个)小(通常为5至12mm)切口来提供到皮下手术部位的通道,通过这些通道手动伸入手术臂。然后手术臂联结到手术自动器械上,所述手术自动器械能够操纵手术臂执行手术操作,如缝合或者热刺穿组织以及烧灼已经被刺穿的血管。从而手术臂在手术过程中延伸穿过切口,所述切口其中之一用于向皮下区域供应气体(特别是二氧化碳),从而在所述皮下区域位置创造出用于操纵手术器械的自由空间。
开放型手术经常需要医生在患者身体上切割相当大的切口,以便能够看到需要治疗的部位并对其提供物理通道。用于执行操作的腹腔镜检查的应用是常见的。执行腹腔镜手术需要在腹壁上切割小口,在腹腔中插入一个小的内窥镜,并且将所述内窥镜捕捉到的图像传送给视频显示器。这样,医生便可以看到腹腔内的情况,而不需要在患者身体上切割相当大的切口,减小了侵入性,并且为患者带来了伤口减小、康复时间缩短并且外观改善的益处。除了内窥镜,执行腹腔镜检查手术需要长的、刚性的工具插入通过腹壁上的切口。
但是,用于执行腹腔镜检查操作的传统技术和工具可能会限制医生的操作灵巧性和视野。给定切口的大小,工具的可操作性受到限制,并且,如果在手术部位需要辅助的视野,还需要增加另外的切口。因此,可以使用自动器械来执行腹腔镜检查操作。但是,传统的自动器械不是连续地连接到外部电源以接收稳定的电力。

图1为根据本公开的电力传递系统的框图;
图2为根据本公开的信息传递系统的框图;以及
图3为示出根据本公开的在传输单元和接收单元之间的电力传递的流程图。
具体实施方式
以上简要概述的本公开的更具体的描述已经被引用到在本说明书中所描述的本公开的实施例中并且在附图中示出。但是,需要注意的是,说明书和附图只是示出了本公开的一些实施例,因此不应被视为对其范围的限制。本公开可以允许等价效果的实施例。
现在将详细解释本公开的示范性实施例。虽然将结合这些实施例对本公开进行描述,但是应该理解的是,所描述的实施例并不意图唯一地限制本公开,而是仅仅具体描述那些实施例。相反地,本发明意图覆盖包含在所附权利要求所限定的本公开的精神和范围内的变化、修改和等同转换。
即使不是在绝大多数情况下,在一些情况下也发现,借助手术自动器械执行MIS操作与手动执行的MIS操作相比,具有诸多优点。这样的手术自动器械可以包括由医生控制的所谓主动装置和作为响应主动装置命令而执行手术的手术自动器械的所谓从动装置,在主动装置与从动装置之间具有提供所需连接的控制系统。从动自动器械可以包括手术臂,每个臂配置成长且窄的棒状,其末端具有一小器械,所述器械(正如相关的手术臂)可以由主动装置操纵或控制。这种器械不仅可以包括例如热切刀、剪刀、缝合工具,还可以包括内窥镜,借助所述内窥镜,手术部位可以在主动装置位置处展示给医生。
进一步,在自动辅助手术或者远距离自动手术中,医生通常操作主控制器来对附着于位于手术部位的自动臂上的手术器械的运动进行远程控制。主控制器可以置于远离患者的位置(例如:与患者在手术室的两端,与患者在不同的房间中或者与患者在完全不同的楼宇中)。主控制器通常包括一个或多个联结到用于夹持手术器械的自动臂的手输入装置,并且主控制器控制与用于使器械在手术部位处关节式运动的自动臂相关的伺服电动机。在手术过程中,手装置提供联结到自动臂的各种手术器械的机械的关节式运动和控制,所述各种手术器械的每一个为医生实现各种手术功能。本公开的示范性实施例可以涉及手动操作医疗器械或者远程操作医疗器械。所述医疗器械可以是自动臂或者连接于自动臂。所述医疗器械可以并入到自动臂内或者附着于自动臂。本领域的技术人员可以预想到多种不同的自动系统和/或结构,并不限于此处所描述的用于实现数据/电力传递能力的自动臂。
结合图1,示出了根据本公开的电力传递系统的框图。系统10包括与医疗器械30(或者体内器械)可操作通信的电力传输单元20。医疗器械30可以是自动臂。电力传输单元20可以由能量源22供给能量。自动臂30可以包括电力接收单元32、能量存储单元34以及器械控制电子单元36。电力传输单元20可以优选以无线方式经由通信链路12与自动臂30的电力接收单元32进行通信。
电力传输单元20可以用于传输电力,而电力接收单元32可以用于从电力传输单元20接收电力。电力传输单元20可以置于人体外,而电力接收单元32可以置于体内器械(例如:自动臂30)上并且可以由人体外移至人体内。电力传输单元20可以连接到能量源22上。体内器械30可以包括至少一能量存储单元34和一器械控制电子单元36。能量存储单元34可以是电池。器械控制电子单元36可以包括逻辑控制器和体内器械驱动器。
另外,可以预想到的是,可以使用多个自动臂,每个自动臂都具有电力接收器件、能量存储器件和/或逻辑控制器件。一个或多个自动器械可以完全置于人体或者患者的体腔内。但是,可以预想到的是,一个或多个自动器械可以部分地插入通过患者的体腔。还可以预想到的是,一个或多个自动臂通过共享信息来进行通信。并且,在器械控制电子单元36中包括的控制器可以购买现货、重新构造或者可以定制现有的控制器来控制本公开的自动组件。本领域的技术人员能够选择适用于自动器械或者体内器械或者微型机器人的控制器。
在操作过程中,电力传输单元20优选向电力接收单元32无线地传输电力。电力传输单元20可以以连续不间断的方式向电力接收单元32无线地传递电力。可以利用电感耦合电力传递方法来无线地传递电力,其中电感耦合电力传递方法允许电力传输单元20和电力接收单元32共享相同的电感器一电容器谐振频率。作为替换,可以利用射频(RF)电力传递方法来无线地传递电力,其中RF电力传递方法允许电力传输单元20和电力接收单元32在共同的频率下操作。
在选择电力供应时,外部电力供应可以采用系留结构(tetheredconfiguration)。但是,示范性实施例包括用电池供应电力。本公开中的自动器械或者体内器械的形式可以使用碱性电池、锂电池和镍镉电池或者本领域公知的任何其他类型的电池。作为替换,由于磁感应是压电感应能量,所以其可以作为另一种可能的电源。此外,本领域的技术人员还可以采用其他的电源,如核能电源、流体动力电源、太阳能电源等,来为本公开的自动器械或者体内器械提供电力。
无线电力传输或者无线能量传递通常是在系统10内发生的过程,其中电能可以从电源传输到电力负荷,而无需互连线。系统10还包括控制逻辑,该控制逻辑能够将可以由无线电力接收装置32接收到的电力传递给无线电力传输装置20。控制逻辑可以并入到器械控制电子单元36内。从而,此处公开的电力传递系统10可以同时无线地接收和传输电力。
例如,传输电路(未示出)可以从在系统10的操作过程中提供给传输电路的直流电压产生具有预定频率的交流电压,并将产生的交流电压提供给传输线圈。还是通过例子,传输电路可以在传输线圈中产生具有预定水平强度的感应场。并入器械控制电子单元36内的控制逻辑可以包括单独的硬件(例如:电路)或者可以包括硬件和软件二者。并入器械控制电子单元36内的控制逻辑可以由电子领域的普通技术人员实施。例如,这一技术可以包括特定功能积分电路,微处理器执行代码,可编程的逻辑阵列等,微处理器执行代码可以被设计用于实施此处描述的功能和方法。并入器械控制电子单元36内的控制逻辑能够将无线电力接收装置32接收到的电力传递给无线电力传输装置20。并入器械控制电子单元36内的控制逻辑可以将电力直接从无线电力接收装置32传递给无线电力传输装置20。例如,控制逻辑可以为传输电路供应从接收电路提供给控制逻辑的直流电压。
在示范性实施例中,例如,可选的电力传输协议可以包括一特定频率,在此频率下,传输电路产生传输电路向传输线圈提供的交流电压。由此,选择第一电力传输协议可以使传输电路产生在特定频率的交流电压,而选择第二电力传输协议可以使传输电路产生在不同频率的交流电压。类似地,特定电力传输协议可以包括例如一特定水平强度的用于传输线圈的感应场。由此,选择第一电力传输协议可以使传输电路产生一特定水平强度的感应场,而选择第二电力传输协议可以使传输电路产生不同水平强度的感应场。
另外,系统10可以具有设定机构,为系统10的用户提供用于选择操作系统10的参数的器件。例如,设定机构可以包括多个可选按钮,每个可选按钮具有与其相关的电力传输协议。由此,当选择一个可选按钮时,并入器械控制电子单元36内的控制逻辑能够进行检测。控制逻辑还能够根据与所选按钮相关的电力传输协议来操作无线电力传输装置20。此方式下,系统10的用户可以选择与待执行的特定手术过程最适合的特定的电力传输协议。例如,自动器械或者体内器械在一些手术过程中比在其他手术过程中需要更多的电力。结果,系统10的用户可以通过选择希望的协议对从电力传输单元20传递给电力接收单元32的电力的量进行控制。
而且,电力传输单元20可以配置成经由多个不同频率信号中的相应一个来传输多个不同功率电平中的每一个。例如,电力传输单元20可以使低功率无线传输器在特定频率上传输,从而为初始通信对系统10的基本组件初始加电。电力传输单元20传输低电平最小电力的特定频率可以是任一自动器械可获得的固定的、预选择的频率信号。此外或者可选择地,传输单元可以利用在传输前和传输过程中使得接收单元自动选择最佳信道(例如:干扰量最少的频率)的自动信道选择技术或者自动信道切换技术来无线地传输电力。换句话说,系统10的用户可以输入特定类型手术的代码,并且系统10可以自动确定从电力传输单元20传输至电力接收单元32所需的电力。
进一步,所存储的信息也可以用于实现电力保护程序,在此程序下,当自动器械并不需要被完全操作时,自动器械被断电或者置于低功率模式。例如,当只需要对自动器械进行部分操作时,自动器械可以进入低耗能模式。可选择地,如果连接到电力传输单元20上的能量源22被断开,则电力接收单元32可以经由置于体内器械或者自动臂30内的能量存储单元34来自动供给能量。
进一步,在以上描述的实施例中,程序控制系统的设计可以不限于有线电源或者有线网络的位置。替代地,程序控制系统的场装置和其他元件可以置于任意位置处,并且,利用无线电力传输器来接收电力,以及利用无线数据通信来与其他程序控制系统装置或设备交换数据。无线电力和数据也使得程序控制系统的设计相对更简单并且更快捷,这是由于重新定位场装置需要移动或安装的线缆或电线相对较少。
在示范性实施例中,系统10也可以具有显示机构(未示出)以向用户提供系统10的操作状态的指示。例如,显示机构可以包括电力指示器(例如,LED),该电力指示器用于向用户指示系统10正在接收电力(见附图2)。例如,当系统10的无线电力接收装置32正在接收电力时,电力指示器可以点亮。此外,电力指示器可以包括信号强度仪表,以允许用户判定传输电力的信号是否强。显示机构还可以包括用于能量存储单元34的电池电量指示器。当可充电电池(或者能量存储单元34)充满电时,电池电量指示器可以点亮。在其他实施例中,电池电量指示器可以示出可充电电池(或者能量存储单元34)中大约有多少电力。由此,系统10的用户可以连续地获知从电力传输单元20到电力接收单元32的电力传递状态。
结合图2,示出了根据本公开的信息传递系统的框图。系统40包括传输单元50和体内器械或者自动臂60。传输单元50可以与能量源52和存储单元54可操作地通信。自动臂60可以包括接收单元62、能量存储单元64、器械控制电子单元66、存储单元68以及LED指示单元70。传输单元50可以经由通信链路42与自动臂60的接收单元62进行通信。
当然,许多不同种类的连接组件或者通信链路可以用于将传输单元50连接到接收单元62。如在此所使用的,“连接组件”意在指的是在系统10、40的至少两个组件之间的有线或者无线的连接器,所述系统10、40在组件之间传输和/或交换信息和/或电力。连接组件可以可操作地联结到控制台/显示器(未示出)和自动器械上,使得在例如自动器械的电子组件之间进行通信并且在例如控制台上进行视觉显示。
根据一个实施例,连接组件可以是有线连接器,例如电线、绳索或者其他物理柔性联结物。有线连接器的一端联结于自动器械,另一端可以联结于诸如控制台/显示器。对于本申请的目的,物理的或者有线的连接器还可以被认为是“系留的(tethered)”或者“系留物(tether)”。有线连接器可以是任意柔软的、易曲折的或者其他能够易成型或者易加工成不同形状或者结构的物理组件。
无线连接器在此处可以被认为是“无系留的”。根据本申请的目的,“无系留装置”、“无线装置”或者“无线连接器”可以是指任意的如下的自动器械:其可以完全封闭于患者体内,从而自动器械在至少一部分手术过程中没有部分置于患者体外,或者替代地,可以是任意的如下的自动器械:其在人体内进行操作,在至少一部分手术过程中,即使是部分也不与任何外部物体物理连接。
存储单元54、68可以包括任意希望类型的易失性存储器和/或非易失性存储器,例如,静态随机存取存储器(SRAM)、动态随机存取存储器(DRAM)、闪存、只读存储器(ROM)等。存储单元54、68可以包括任意希望类型的大容量存储装置,包括硬盘驱动器、光学驱动器、磁带存储器等。存储单元54、68可以存储与传输单元50和自动臂60内的多个不同组件有关的信息。在存储单元54、68中存储的信息将在下面的内容中进一步阐述。
LED指示单元70可以通知或告知或指示系统10、40的用户电力是否在传输单元50和接收单元62之间进行了传递。
结合图3,示出了根据本公开的在传输单元和接收单元之间的电力传递的流程图80。
在步骤82中,可以经由传输单元将信息(数据/电力)传输至一个或多个医疗器械。在步骤84中,可以经由一个或多个接收单元通过一个或多个医疗器械接收信息。在步骤86中,可以经由器械控制电子单元在一个或多个医疗器械处对信息进行处理,同时所述一个或多个医疗器械被移入和移出人体。在步骤88中,可以将升级信息传输至传输单元。在步骤90中,可以将升级信息存储于与传输单元进行通信的存储单元中。在步骤92中,根据从一个或多个接收单元接收到的升级信息,可以调节一个或多个医疗器械的一个或多个参数。然后该过程的第一个周期或者第一个迭代完成。但是,这一过程可以是一个连续的迭代过程。换句话说,所述过程的步骤可以进行多个周期或迭代,其中医疗器械的参数被不断调整。
在一可选实施例中,手术室工作台包含用于多个手术用自动操纵器或者臂或者器械的电子的和机械的接口。可以利用优选位于远离手术室工作台的多个控制台或者外部源(例如:手术工作站、个人电脑等)远程控制自动器械,所述多个控制台或者外部源例如是但不限于在医院内部连接到医院的局域网和/或远程网络,例如因特网。控制台可以与置于人体或者患者的体腔中的一个或多个自动器械联合操作。也就是说,控制台可以用于对置于患者的体腔内的一个或多个自动器械进行操作。如在此所使用的,“控制台”可以意在是指控制器或者可操作的集线器。多个可视显示器可以连接于多个控制台用于提供由一个或多个自动器械捕捉到的体腔的视觉反馈。
在一个实施例中,可视显示器可以是标准的视频监视器。在一可选实施例中,可视显示器可以经由在一个或多个自动器械上的成像组件向医生显示二维视觉反馈、三维视觉反馈或者立体成像。本领域的普通技术人员可以识别来自摄像机的信号可以被处理从而为不同类型的显示装置生成显示信号,所述不同类型的显示装置包括但不限于:配置为显示NTSC(国际电视系统委员会)信号的电视机,配置为显示的PAL(逐行倒相)信号的电视机,基于电脑监视器的阴极射线管、LCD(液晶显示器)监视器和等离子显示器。

在一可选实施例中,自动器械可以利用基站的通信能力与控制台的通信管理器进行通信。基站可以通过基于有线的连接器链接到控制台的有线通信链路。应该指出的是,连接和链接可以在现有的手术室通信基础网络中,从而基站可以联接于电的/机械的连接工具上。应该指出的是,连接和链接可以完全符合IP光纤网络协议,用于与通过基站对自动器械进行控制的远程控制台连接。每一基站和/或自动器械都可配有IP地址,以便于利用通信管理器与控制台进行通信。例如,IP地址可以分配给控制单元中的臂控制器。网络还可以包括本领域中公知的转换器和路由器,以能够与连接于室内网络的其他电信设备进行通信。网络协议的例子可以例如是但不限于以太网/IP和TCP/IP。但是,本领域的普通技术人员可以容易地理解,其他适合的通信介质和网络协议也可以被采用。

在另一可选实施例中,多个信息管理器可以用于控制和操纵信息。通信管理器可以提供数据信号到数据管理器/数据管理器到数据信号的通信,以及控制信号到控制管理器/控制管理器到控制信号的通信。数据库管理器可以提供例如但不限于:图像数据到图像数据库/图像数据库到图像数据的通道,与自动器械的各种元件的运行/安装相关的数据,以及各种位置/定向传感器数据,并且用于为位置和定向管理器提供所需的数据。控制管理器可以提供监视自动器械的操作。位置/定位管理器可以负责例如但不限于接收来自数据管理器的传感器数据,从而计算自动器械的位置和定向。计算出的位置/定向信息管理器可以用于例如但不限于致动显示管理器和控制管理器。配置管理器可以提供例如但不限于自动器械在特定的手术操作中的动态配置。动态配置可以是自动的、半自动的和/或手动操作员干预。如由操作员(如医生)设定的,软件的显示管理器可以调整/提供计算出的位置/定向信息以及在用户接口的控制台的显示器上的患者/工具图像。
在一种实施中,通过将自动器械相对于控制台放置于体腔内,电力传递系统10可以允许医生确定并维持自动器械相对于一个或多个控制台的空间定向。系统10的其他益处可以包括但不限于:为医生提供训练工具,减少或消除对医生在现场的需要,以及减少自动手术系统的成本。
在另一示范性实施例中,两个或更多个自动器械可以可操作地彼此联结,并且可联结到外部单元(例如:控制台,个人计算机或者网络等)。根据具有两个自动器械的一个实施例,所述两个自动器械可以通过柔线有线连接器或者无线连接器而可操作地彼此联结并且连接于外部单元。也就是说,所述两个自动器械可以通过分别联结于每个自动器械的柔线有线连接器而可操作地彼此联结,并且,每个自动器械也可以利用柔线连接器可操作地联结于外部单元。
综上所述,本公开通过提供半自主和自主的手动或者远程控制的在体内(特别是人体内)使用的自动器械,便于腹腔镜检查和其他微创型手术技术在更广泛的操作范围内的应用。本公开提供了可以插入待治疗部位(例如腹部)的在活体内自动的有线和无线操纵器、成像、电力和传感器装置。所述装置克服了目前的腹腔镜检查摄像机和工具相关的局限性,为手术团队提供了对手术区域的多角度视野、体内患者监视能力、体内操纵灵活性以及电力控制能力。可以预想到,自动装置在活体内的时刻能够帮助医生直接操纵组织。还可以预想到可以连续不间断地为自动装置提供电力的能力。换句话说,可以预想到,可以从患者体外向任何的体内自动器械连续地无线传递电力。由此,与已知的需要由电线或者线缆和/或电池提供场装置电力(例如:交流(AC)电力或者直流(DC)电力)的系统不同,此处所描述的系统和方法的示例可以用于在过程控制系统中实现场装置(例如:温度传感器、压力传感器、状态(开/合)传感器、致动器、电力传感器等),所述场装置利用无线传输的电力操作并且在过程控制系统内进行无线通信。
根据以上描述并结合各个附图,本领域技术人员可以理解:在不背离本公开范围的情况下,可以对本公开作出某些修改。虽然本公开的若干具体实施例已经在附图中示出,但本公开并不仅限于此,它只表明本公开的范围与本领域所允许的一样宽泛并且也应当同样阅读本说明书。因此,以上描述不应解释为限制,而仅仅是特定实施例的范例。本领域技术人员还可以想象到所附权利要求的范围和精神内的其他修改。
