用于机电手术装置的包封插头组件
相关申请的交叉引用
本申请要求2019年2月22日提交的美国临时专利申请第62/808,925号的权益和优先权，所述美国临时专利申请的全部公开内容以引用的方式并入本文中。
技术领域
本公开涉及手术装置。更具体地说，本公开涉及其中具有包封插头组件的用于执行手术程序的手持式机电手术系统。
背景技术
一种类型的手术装置为圆形夹持、切割和钉合装置。这类装置可用于重新附接先前横断的直肠部分的手术程序或相似程序中。传统的圆形夹持、切割和钉合装置包括手枪或线性握把式结构，其具有从其延伸的细长轴和支撑在细长轴的远侧末端上的钉仓。在此情况下，医生可将圆形钉合装置的装载单元部分插入到患者的直肠中，并且沿着患者的结肠道向上朝向横断的直肠部分操纵装置。装载单元包括具有多个钉的仓组件。沿横断的结肠的近侧部分，可将砧座组件缩拢系于其中。替代地，如果需要，那么砧座部分可穿过邻近横断的结肠的切口插入到结肠中。砧座和仓组件朝向彼此接近，并且钉从仓组件朝向砧座组件弹射，从而在组织中形成钉以实现端对端吻合，并且起动环形刀以对所夹持组织部分的一部分进行取芯。在实现端对端吻合之后，将圆形钉合装置从手术部位移除。
许多手术装置制造商也已经开发出用于操作和/或操纵末端执行器的专有动力驱动系统。动力驱动系统可包括可重复使用的动力手柄组件和可移除地连接到动力手柄组件的一次性末端执行器。
供与现有动力手术装置和/或手柄组件一起使用的许多现有末端执行器为由线性驱动力驱动的。举例来说，用于执行内胃肠道吻合程序、端对端吻合程序和横向吻合程序的末端执行器为由线性驱动力致动的。由此，这些末端执行器与使用旋转运动的手术装置和/或手柄组件不兼容。
为了使线性驱动的末端执行器与使用旋转运动来递送电力的动力手术装置兼容，需要适配器以将线性驱动的末端执行器与动力旋转驱动的手术装置互连。这些适配器还可重复使用，并且由此，需要能够承受多次杀菌循环。
随着这些适配器变得更加复杂并且包括各种电子部件，需要安置在适配器内的可承受多次高压灭菌循环的电子部件。举例来说，电子部件可包括由对消毒化学品(如氢氧化钾(KOH))的高pH环境具有高度抵抗力并且还可抵抗高温高压灭菌蒸汽和高压灭菌的相关压力(+atm/-atm)的材料制成的柔性或带状电缆。还期望这些电子部件的壳体也由对消毒化学品(KOH)的高PH环境具有高度抵抗力并且还可抵抗高温高压灭菌蒸汽和高压灭菌的相关压力(+atm/-atm)的材料制成。

在实施例中，带状电缆105、107的基底由覆铜聚酰亚胺形成，如或其为由杜邦(DuPont)拥有的注册商标。在一些实施例中，带状电缆105、107的基底由高温材料形成，如/>HT，其也为由杜邦拥有的注册商标。
在实施例中，预期到，带状电缆105、107可全部或部分地由液晶聚合物(LCP)制成。与不带LCP的带状电缆相比，LCP对高PH环境和高压灭菌更具抵抗力。带状电缆105、107可包括多个层，例如，包括作为内层或外层的聚酰亚胺层。形成带状电缆105、107的多个层可使用热粘结层压(例如，将各层熔融/融合在一起)或通过使用粘合剂层将各层彼此粘结来粘结。在其它实施例中，带状电缆105、107的基底由粘结到液晶聚合物(LCP)膜的覆铜形成。
应理解，带状电缆105、107的基底被配置成允许制造单侧或双侧柔性电路、多层柔性电路和刚性柔性电路。带状电缆105、107的基底的层可通过例如层压、熔接和/或使用粘合剂，以及在本领域的技术人员的认知内的其它方法和材料彼此接合。
插头组件110包括限定面向近侧的孔112a的壳体112，所述面向近侧的孔112a被配置成容纳远侧线束组件106的带状电缆107的远侧末端部分107a。电触头或刀片114、116支撑在壳体112内，其中每个电触头114、116包括从壳体112向远侧突出的相应远侧末端部分114a、116a。电触头114、116可以任何合适的方式固定在壳体112的孔112a内，例如，压配合、摩擦配合、搭扣配合、钉接、熔接、用树脂材料等罐封(用于电触头114、116在壳体112内的液密保持)、胶合等。
参考图12A、12B、13和14，每个电触头114、116分别包括在其相应近侧末端部分114b、116b中形成和/或从其突出的一对凸块114c、116c。凸块114c、116c限定用于电连接到带状电缆107的远侧末端部分107a的焊接区域。具体地说，带状电缆107的远侧末端部分107a包括形成在其第一侧边缘中的第一对焊接凹槽107b1和形成在其第二侧边缘中的第二对焊接凹槽107b2。第一对焊接凹槽107b1被配置成与电触头114的一对凸块114c对齐，并且第二对焊接凹槽107b2被配置成与电触头116的一对凸块116c对齐。第一对焊接凹槽107b1和第二对焊接凹槽107b2中的每个焊接凹槽可限定用于与电触头114、116的相应凸块114c、116c电连接的焊盘(例如，城堡型焊盘)。预期到，带状电缆107的远侧末端部分107a可经由浸锡工艺、化学镀镍浸金(ENIG)工艺或本领域技术人员已知的类似工艺焊接或固定到每个电触头114、116。
参考图7-11，插头组件110包括安置在壳体112的面向远侧的孔112b(参见图12A)内的密封构件120。密封构件120包括形成在其中的一对槽，用于使电触头114、116的远侧末端部分114a、116a从中穿过。密封构件120被固定到壳体112的远侧末端，并且包括从壳体112的远侧末端延伸的远侧部分120a，以及被配置成通过壳体112的至少一个侧表面容纳并且与其形成互锁的近侧部分120b。密封构件120可包括周向脊122，其被配置成接合再装载件40的插头插座的内壁(未示出)，以促进适配器组件30的插头组件110与再装载件40的插头插座之间的摩擦配合和液密密封。
密封构件120可由硅酮、橡胶、塑料、聚合物或任何其它合适的材料形成。
如上文所提及，插头组件110的电触头114、116的相应远侧末端部分114a、116a穿过并从密封构件120延伸。电触头114、116的远侧末端部分114a、116a被配置成与再装载件40的互补插头插座的相应触头构件电联接(未示出)。
参考图15，在将电触头114、116和带状电缆107的远侧末端部分107a安置在壳体112内的情况下，壳体112的面向近侧的孔112a可填充有耐消毒和杀菌操作(例如，洗涤、漂洗、高压灭菌等)的包封材料130(例如，树脂、丙烯酸类树脂)。
壳体112可为透明的或接近透明的，从而使得能够使用光或UV可固化的包封材料130。壳体112的透明性允许在插头组件110完全组装之后固化包封材料130。因此，壳体112可由聚苯砜(PPSU)使用注射模制工艺、挤出工艺等制成，或者由对于光/UV固化也为透明的聚砜(PSU)制成。在实施例中，壳体112可由不透明材料制成，其条件是选择可固化而不需要UV或光固化工艺的室温硫化(RTV)包封。
现在转到图16-20，根据本公开的替代实施例的插头组件被整体上指定为210。插头组件210基本上类似于插头组件110，并且为了简洁起见，下文将仅详细描述它们之间的差异。
参考图16-18，示出并且描述供与插头组件210一起使用的电气组件100的带状电缆207的远侧末端部分207a。带状电缆207的远侧末端部分207a被分开、分割或分叉，以包括由间隙或空间207e分隔的一对向远侧延伸的指形件207c、207d。
带状电缆207的远侧末端部分207a包括形成在第一指形件207c的第一侧边缘中的第一对焊接凹槽207b1和形成在第二指形件207d的第二侧边缘中的第二对焊接凹槽207b2。第一对焊接凹槽207b1被配置成与电触头114的一对凸块114c对齐，并且第二对焊接凹槽207b2被配置成与电触头116的一对凸块116c对齐。第一对焊接凹槽207b1和第二对焊接凹槽207b2中的每个焊接凹槽可限定用于与电触头114、116的相应凸块114c、116c电连接的焊盘(例如，城堡型焊盘)。预期到，带状电缆207的远侧末端部分207a的第一指形件207c和第二指形件207d可分别经由浸锡工艺、化学镀镍浸金(ENIG)工艺或本领域技术人员已知的类似工艺焊接或固定到每个电触头114、116。
现在参考图18-20，示出并且描述插头组件210的壳体212。壳体212限定面向近侧的孔212a，其被配置成容纳带状电缆207的远侧末端部分207a。电触头或刀片114、116支撑在壳体112内，其中每个电触头114、116包括安置在相应腔212c、212d(图20)内并且限定在其内并且从壳体212向远侧突出的相应远侧末端部分114a、116a。电触头114、116可以任何合适的方式固定在壳体212的孔212a内，例如，压配合、摩擦配合、搭扣配合、钉接、熔接、用树脂材料等罐封(用于电触头114、116在壳体212内的液密保持)、胶合等。
壳体212包括安置在面向近侧的孔212a内的中心的向近侧延伸的肋或壁212e。当电触头114、116和带状电缆207的远侧末端部分207a位于壳体212内时，肋212e被配置和定尺寸成基本上填充在带状电缆207的远侧末端部分207a中限定的间隙207e(如上所述)。肋212e可为壳体212的集成部件，并且因此可由与壳体212相同的导电电阻材料构成。根据本公开预期到，肋212e可与面向近侧的孔212a的包封材料130(例如，树脂、丙烯酸类树脂)结合工作，以阻止水分进入插头组件210，并且阻止由带状电缆207的远侧末端部分207a的第一对焊接凹槽207b1和第二对焊接凹槽207b2限定的焊盘的短路。
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，以上描述不应解释为限制性的，而仅仅是作为实施例的例证。本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。
