Description
本申请要求2018年10月30日提交的第62/752,516号美国临时专利申请的权益和优先权，所述临时专利申请的整个公开内容以引用的方式并入本文中。
技术领域
本公开涉及供与手术装置一起使用的负载感测装置。更具体来说，本公开涉及与用于执行外科手术程序的机电手术系统一起使用的负载感测装置，其具有可重复使用组件和单次使用组件，例如末端执行器和适配器。
背景技术
用于将紧固件或钉施加到组织的手术紧固件设备是众所周知的。这些紧固件设备包含单次使用器械，其预载有一个或多个钉且在单次使用之后可抛弃。多次使用器械也是可用的并且预载有多个钉。多次使用器械可包含机电(例如，供电式)的或手动致动的手柄组合件，和手术加载单元。加载单元可以是单次使用加载单元(SULU)或多次使用加载单元(MULU)。加载单元包含主体和末端执行器，并且直接或经由可联接到手柄组合件的适配器组合件附接到手柄组合件。末端执行器可包含容纳多个钉的仓。在使用之后，加载单元可从适配器组合件移除且用新的加载单元替换以执行额外钉合和/或切割操作。驱动组合件支撑于加载单元内且可与适配器组合件的相关联驱动机构接合以致动加载单元。归因于驱动组合件的机械组件的致密封装，用于包含传感器的空间较少。相应地，需要可放置在加载单元内以监测驱动组合件和加载单元的其它组件的操作的负载感测装置。
发明内容
供电式手术器械可包含用于在其操作期间提供反馈的各种传感器。本公开提供安置于柔性电路衬底上的负载感测装置，从而允许将负载感测装置放置在收缩空间中，例如加载单元和手术器械的其它组件。
根据本公开的负载感测装置包含应变计，其具有安置于例如聚酰胺等电介质衬底上的由例如康铜等电阻性金属合金形成的导电迹线。应变计结合或以其它方式固定到组件的表面，包含但不限于在加载单元的一个或两个夹钳部件内。随着上面安装应变计的组件膨胀或收缩(即，施加应变)，应变计上的导电迹线也膨胀或收缩，借此改变应变计的总电阻。电阻的改变影响供应给应变计的测量信号。在实施例中，应变计可布置在惠斯通桥电路配置中。接着测量电路的振幅的改变以确定应变量。
应变计的典型应用为使得其放置在特定关注点上来测量应变。此可用于经验测试，从而寻找归因于特定加载条件或力转换器的设计的实际应变，其中多个应变计放置和布置于某一零件上以输出校准后的信号来测量力。应变计的工作原理是基于由化学式(I)：R＝ρ(l/A)的Pouillett定律限定的电阻率，其中R为电阻，ρ为材料电阻率，l为材料的长度，且A为材料的横截面面积。应变计包含高电阻金属的单个迹线，其布置成使得迹线的长时间操作在变形相关方向上。因此，应变计是可变电阻器，其在应变计结合到的表面归因于应变改变其长度时改变电阻。当应变计结合到的材料使l长度变形时，Pouillett定律的变量改变，从而致使电阻改变，其可使用惠斯通桥电路测量。
可基于应变计结合到的表面的变形来校准应变计以改变电阻的比例量。此属性被称为仪表灵敏度因数(gauge factor)且由以下公式(II)：GF＝(ΔR/R)/∈限定，其中GF为仪表灵敏度因数，R为标称电阻，ΔR为电阻的改变，且∈为应变。仪表灵敏度因数在由应变计制造商限定的范围内是恒定的。对于典型应用，恒定的仪表灵敏度因数通常用于测量应变。然而，存在在整个应变计中具有不同仪表灵敏度因数可能是有用的情形。在本公开中，应变计沿着手术缝合器的夹钳部件的沟道放置以测量归因于组织收缩的沟道弯曲。随着还弹出钉的驱动组合件移动跨越沟道以执行射击，I形梁附近的应变计区域不再弯曲且实际上为非活动。因此，如果I形梁处于射击过程的中途，则归因于弯曲仅产生信号的一半。为了维持信号的振幅在整个射击过程中恒定，需要具有不同仪表灵敏度因数的应变计。通过将应变计的远侧部分制造为较敏感，或具有较高仪表灵敏度因数，信号振幅可保持较高。
传统应变计可具有恒定的仪表灵敏度因数，或针对给定应变恒定的电阻改变。因此，通过改变应变计上的导电迹线的整体形状，可产生不同信号响应。本公开提供横跨夹钳部件的长度的应变计，使得当加载单元的I形梁纵向行进穿过夹钳部件以夹持、缝合和切割组织时，存在安置在致动滑块的远侧的应变计的有源区。如上所述，问题是，随着致动滑块纵向移动，应变计的有源部分减小，从而致使整个应变计的平均效应，这降低电阻改变和因此总体电信号。当前，传统应变计始终具有恒定仪表灵敏度因数。本公开提供各种形状和尺寸(且确切地说，其导电网格)的应变计，使得应变计的不同区域具有不同仪表灵敏度因数，借此限制平均效应。
根据本公开的应变计还可安置于柔性电路上。传统应变计需要焊料连接或线接合以便完成电路。这可能导致潜在故障点，并且还增加应变计的厚度，从而防止其放置在加载单元内。根据本公开的应变计还可包含信号、功率和接地引线，其也作为迹线安置在柔性电路上。这允许将应变计放置在加载单元内。
应变计包含具有例如聚酰胺等电介质衬底上的由例如康铜等金属合金形成的迹线的电阻材料。在实施例中，用于承受应变的具有负热电阻系数、高电阻率和强机械特性的任何合金可用于形成电阻材料。电阻材料的迹线制造为使得其电阻响应于应变计附接到的组件变形而最佳地改变。应变计还包含安置于电阻材料上方的导电材料。导电材料可由例如铜等低电阻率金属形成。
通过在第一(例如，近侧)部分中以预定图案且在第二(例如，远侧)部分中以不间断层沉积电阻材料来形成应变计。电阻材料的预定图案被掩蔽，且导电材料迹线直接安置在电阻材料的不间断层上方。此配置避免需要额外绝缘层，借此使应变计的厚度最小化。因为电阻材料具有比导电材料高的电阻，所以电流仅流动穿过安置于电阻材料的不间断层上方的导电材料。
根据本公开的一个实施例，提供一种手术末端执行器。所述手术末端执行器包含：砧座组合件；仓组合件，其包含多个紧固件；驱动组合件，其可纵向移动以相对于仓组合件接近砧座组合件；以及应变计电路，其安置于仓组合件内，所述应变计电路被配置成测量由驱动组合件施加在仓组合件上的应变。
根据本公开的另一实施例，提供一种手术器械。手术器械包含：手柄组合件，其包含控制器和电源；适配器组合件，其包含联接到手柄组合件的近端部分和远端部分；以及加载单元，其联接到适配器组合件的远端部分。加载单元包含手术末端执行器，所述手术末端执行器具有：砧座组合件；仓组合件，其包含多个紧固件；以及驱动组合件，其可纵向移动以相对于仓组合件接近砧座组合件。手术末端执行器还包含应变计电路，其安置于仓组合件内且电联接到控制器和电源，所述应变计电路被配置成测量由驱动组合件施加在仓组合件上的应变且将测量信号发射到控制器。
根据以上实施例中的任一个的一个方面，应变计电路包含柔性电路。所述柔性电路可包含第一柔性电介质衬底；电阻性传感器层，其安置于第一柔性电介质衬底上方；导电层，其安置于电阻性传感器层上方；以及第二柔性电介质衬底，其安置于电阻性传感器层和导电层上方。
根据另一方面，电阻性传感器层包含应变计和连续层。导电层包含第一导电迹线和第二导电迹线，其中的每一个联接到应变计。
根据另一方面，应变计包含具有第一端和第二端的连续迹线，所述第一端联接到所述第一导电迹线且所述第二端联接到所述第二导电迹线。
根据又一方面，应变计包含可变仪表灵敏度因数。应变计可包含可变横截面。应变计可进一步包含一对平行网格线，其中的每一个具有锥形形状，借此提供可变横截面。应变计可进一步包含不同长度的多个网格线，从而提供可变横截面。
根据一个方面，应变计电路包含应变计部分和引线部分，所述引线部分包含具有至少一匝的松弛部分。

本公开涉及可与手术器械一起使用的柔性应变计电路。确切地说，根据本公开的柔性应变计电路的大小允许将这些电路放置在加载单元和其末端执行器的紧密界限内。柔性应变计电路还包含具有可变仪表灵敏度因数的应变计以补偿在使用期间施加在末端执行器上的可变应变。由于致动末端执行器的驱动组合件的纵向平移而导致可变应变。通过提供应变计的可变横截面面积来实现应变计的可变仪表灵敏度因数。
参看图1，供电式手术器械10包含手柄组合件20，其被配置成与适配器组合件30选择性地连接，所述适配器组合件继而被配置成与例如加载单元40等末端执行器选择性地连接。尽管通常被称为供电式手术器械，但预期，手术器械10可以是手动致动的且可包含各种配置。
手柄组合件20包含手柄壳体22，其具有下部壳体部分24、从下部壳体部分24延伸和/或支撑在下部壳体部分24的一部分上的中间壳体部分26，和从中间壳体部分26延伸和/或支撑在中间壳体部分26的一部分上的上部壳体部分28。如图2所示，上部壳体部分28的远侧部分限定鼻部或连接部分28a，其配置成接纳适配器组合件30的近端部分30b。
参考图2，连接部分28a包含具有多个电接触件31的电插座29，所述电接触件与手柄组合件20(图3)的电子(例如，主控制器38)和电组件(例如，电源37)电连通。适配器组合件30包含配置成接合电插座29的对应电连接器32。电连接器32还包含多个电接触件34，其接合且电连接到其对应电接触件31。
参看图3，手柄组合件20包含联接到电源37的一个或多个电机36。手柄组合件20还包含主控制器38，其用于操作手柄组合件20、适配器组合件30和加载单元40的电机36和其它电子组件。电机36联接到对应驱动轴39(图2)，所述对应驱动轴配置成将插口33接合在近端部分30b上，使得在插口33上施加驱动轴39的旋转。
参看图4和5，适配器组合件30包含管状壳体30a，所述管状壳体30a在配置成用于可操作地连接到手柄组合件20的连接部分28a的近端部分30b和配置成用于可操作地连接到加载单元40的相对远端部分30c之间延伸。适配器组合件30包含致动组合件35，其中的每一个联接到插口33中的一个。致动组合件35被配置成将插口33的旋转运动转换成线性运动和/或旋转运动，使得适配器组合件30配置成将由手柄组合件20提供的旋转运动转变成轴向平移，用于使适配器组合件30围绕纵向轴线X-X旋转，铰接加载单元40，夹持组织，弹射紧固件，以及切割紧固的组织。
参考图1和6，示出加载单元40的实施例。加载单元40包含近侧主体部分42和手术末端执行器44。近侧主体部分42可拆卸地附接到适配器组合件30的远端部分30c，并且末端执行器44可枢转地附接到近侧主体部分42的远端。末端执行器44包含砧座组合件46和仓组合件48。仓组合件48相对于砧座组合件46枢转并且在打开或未夹持位置和闭合或夹持位置之间可移动。近侧主体部分42包含驱动组合件50和铰接连杆52。
驱动组合件50包含具有远端部分54a和近侧接合区段54b的柔性驱动梁54。远端部分54a包含具有刀55a的I形梁55。I形梁55配置成行进通过砧座组合件46仓组合件48，借此朝向仓组合件48推动砧座组合件46以夹持组织。近侧接合区段54b包含直径相对的向内延伸指状件54c，其接合驱动部件56(图5)以将驱动部件56固定地紧固到柔性驱动梁54的近端。驱动部件56由适配器组合件30的致动组合件35之一致动。
末端执行器44的仓组合件48包含可移除地支撑在载体60中的钉仓58。钉仓58限定中心纵向狭槽58a，并且呈直线的多排钉保持狭槽58b定位在中心纵向狭槽58a的每一侧上。钉保持狭槽58b中的每一个接收单个钉62和钉推动器64的一部分。在手术器械10的操作期间，驱动组合件50对接致动滑块66并且推动致动滑块66通过钉仓58。随着致动滑块66移动通过钉仓58，致动滑块66的凸轮楔循序接合钉推动器64以在钉保持狭槽58b内垂直移动钉推动器64，并且循序地从其弹射单个钉62，用于抵靠砧座组合件46的砧板46a形成。
手术加载单元40的近侧主体部分42包含具有从手术加载单元40的近端延伸的钩状近端部分52a的铰接连杆52，其接合联接到适配器组合件30的致动组合件35中的另一个的相对铰接连杆(未图示)。铰接连杆52具有可枢转地紧固到末端执行器44的远端部分52b。
参考图7-9，末端执行器44包含安置于仓组合件48内的应变计电路68。在实施例中，第二应变计电路可安置于砧座组合件46内。载体60包含限定在载体60的内底表面60a和内侧表面上的凹陷70。凹陷70被配置成容纳应变计电路68，同时允许钉仓58配合在应变计电路68上方。应变计电路68可通过结合紧固在凹陷70内。
参考图10和11，应变计电路68包含应变计部分72和引线部分74。应变计部分72包含应变计76，且引线部分74包含将应变计76联接到主控制器38和电源37的第一和第二导电迹线78a和78b。引线部分74可包含任何数目的片段以允许将应变计电路68布设在加载单元40内，如图9所示。引线部分74还包含具有一匝或多匝82的松弛部分80，所述一匝或多匝允许松弛部分80在加载单元40内的额外移动自由度。迹线78a和78b中的每一个分别联接到安置于引线部分74的近端部分处的接触垫79a和79b。接触垫79a和79b被配置成联接到适配器组合件30的电接触件(未图示)，所述电接触件继而将应变计电路68联接到手柄组合件20的电源37和主控制器38。
参考图10-13，应变计电路68形成为具有第一柔性电介质衬底88和第二柔性电介质衬底90的柔性电路86，所述柔性电介质衬底围封电阻性传感器层92和导电层94。电介质衬底88和90可由任何合适的柔性电介质材料形成，包含(但不限于)聚酯、聚酰亚胺、聚萘二甲酸伸乙酯、聚醚酰亚胺、氟聚合物、聚醚醚酮及其组合。电阻性传感器层92可由具有负热电阻系数(以使温度变化对电阻的影响最小化和/或防止所述影响)、高电阻率(高于45.0x10-8Ω·m的电阻率)，和承受机械应变的强机械特性的任何金属合金形成。用作电阻性传感器层92的合适的合金包含由铜、镍、锰及其组合形成的任何合金，例如康铜和锰铜。导电层94由例如金属(例如铜、银等)、金属合金、导电聚合物及其组合等任何合适的导电材料形成。
电阻性传感器层92包含应变计76和安置于第一电介质衬底88上的连续片段96。应变计76包含具有第一端100和第二端102的连续迹线98，所述连续迹线98布置成任何合适的网格图案，例如具有在相对端处互连的多条平行网格线104的图案，如图13所示。连续迹线98的第一和第二端100和102联接到导电层94的第一导电迹线78a和第二导电迹线78b。第一和第二导电迹线78a和78b叠加在电阻性传感器层92的连续片段96上。第一和第二导电迹线78a和78b中的每一个联接到连续迹线98的第一和第二端100和102，从而实现经由应变计76发射测量信号。
在形成导电迹线78a和78b之前，可掩蔽应变计76。电阻性传感器层92和导电层94可使用任何消减(例如，蚀刻)或加成(例如，丝网印刷)技术施加到第一电介质衬底88，用于在柔性电介质衬底上形成金属层。因为电阻性传感器层92具有比导电层94的导电迹线78a和78b高的电阻，所以测量信号的电流仅行进穿过应变计76以及导电迹线78a和78b。此配置避免需要电阻性传感器层92和导电层94之间的绝缘层，借此使应变计电路68较薄且允许将其放置在载体60的凹陷70内。
应变计电路68被配置成在驱动组合件50的致动期间测量施加在末端执行器44(且确切地说，仓组合件48)上的应变。如上所述，随着驱动组合件50向远侧移动，驱动组合件50闭合砧座组合件46且推动致动滑块66穿过钉仓58。致动滑块66接合钉推动器64，钉推动器弹射钉62，从而密封组织。同时，刀55a还切割的密封组织。相应地，在驱动组合件50的移动期间，载体60归因于组织收缩和其它力而弯曲。
随着驱动组合件50(且确切地说，I形梁55)移动跨越沟道以执行夹持、缝合和切割，应变计76的近侧区域，即在I形梁55的近侧的区域不再弯曲且实际上非活动。因此，如果I形梁55处于致动移动过程的中途，则应变计76仅产生信号的一半。本公开提供防止信号在整个射击过程中减小的新颖的应变计设计。在实施例中，根据本公开的应变计具有不同仪表灵敏度因数。确切地说，应变计的远侧部分较敏感，例如具有比应变计的近侧部分高的仪表灵敏度因数，使得测量信号的振幅随着射击的进行而变高。
应变计76的总电阻改变取决于应变计76上施加的应变。因此，如果应变为恒定的，正如轴向负载中，则可使用仪表灵敏度因数来计算已知应变。然而，载体60充当悬臂梁，其由I形梁55驱动组合件50弯曲。载体60和其内安置应变计76的凹陷70开始向I形梁55的远侧弯曲，因此，在其中应变计76太长(例如，3厘米以上)的实施例中，I形梁55的近侧不存在弯曲。
与I形梁55的改变的位置相关的应变可使用公式(III)：∈a＝βe-αx计算，其中∈a为轴向应变，β和α为常数，且x为砧座组合件46和仓组合件48内I形梁55的位置。
以下公式(IV)可用于确定针对给定应变的电阻改变：
其中D为应变计76的横截面面积的要素。
总电阻改变可使用公式(V)确定为从I形梁55的位置k到再加载件的端部L的公式(IV)的积分：
为了在I形梁55的所有位置上存在恒定电阻改变，相对于位置k的公式(V)的导数应为恒定的，如公式(VI)中所展示：
通过代入公式(IV)评估公式(VI)，导出以下公式(VII)：
关注公式(VII)的第二项，其展示如果电线横截面的改变除以电线横截面等于I形梁55的所有位置的轴向应变，则将存在恒定电阻改变。公式(VII)假设恒定弯曲特性，且归因于泊松效应(Poisson’s effect)的横截面改变为最低限度的。因此，公式(VII)示出改变应变计上的电线或迹线的形状可产生恒定的电阻改变。
根据本公开的应变计还可并入有具有恒定电阻改变以提供可变仪表灵敏度因数的其它网格图案。参看图14，展示应变计176，其可用于应变计电路68中。应变计176包含具有第一端200和第二端202的连续迹线198。连续迹线198包含在相对端处互连的具有不同长度的多个平行网格线204。网格线204的长度从外网格线204向内网格线204减小。确切地说，网格线204布置成多对，两个第一对208为最长(两条最外网格线204除外)，两个第二对210具有中间长度，且中间对212为最短。此外，网格线204围绕由应变计176限定的纵向轴线布置成对称图案。据设想，应变计176可包含任何数目的网格线204，其布置成具有减小的长度(从外向内)的任何数目的对，以便通过改变纵向方向中应变计176的横截面面积来补偿I形梁55的可变应变。改变横截面面积，即通过增加纵向方向中近侧方向与远侧方向之间的面积，实现跨越应变计176的整个长度恒定的ΔR。
参看图15，展示应变计276，其也可用于应变计电路68中。应变计276包含在远端300和302处互连的一对平行网格线304。网格线304围绕由应变计76限定的纵向轴线布置成对称图案。网格线304中的每一个具有锥形形状，其在纵向方向中在近侧方向与远侧方向之间具有减小的宽度。此配置还通过改变纵向方向中应变计276的横截面面积来补偿I形梁55的可变应变。改变横截面面积实现了跨越应变计276的整个长度恒定的ΔR。
应理解，可对目前公开的适配器组合件的实施例进行各种修改。因此，上文的描述不应解释为限制性的，而仅仅是作为实施例的例证。所属领域的技术人员将设想在本公开的范围和精神内的其它修改。
