Description
技术领域
本发明主要涉及一种用于外科器械的支撑材料,及一种被构造成可释放地连接到外科器械的端部执行器组件的支撑材料。
背景技术
一种外科器械,例如外科钉合器,可设置用于在外科手术中将钉释放到组织中。在各种实施方式中,外科钉合器可以包括布置在外科钉合器的末端上的端部执行器。所述端部执行器可设置在患者身体内的壁内的套管或套管针内,并至少部分穿过套管或套管针滑动,从而外科医生可以利用端部执行器在外科手术部位进行操作。在各种实施方式中,端部执行器可以包括具有钉仓的第一夹钳构件和具有砧座的第二夹钳构件。第一夹钳构件和第二夹钳构件可被构造成相互接近移动以夹住其间的组织层并对其施加压力。在至少一种实施方式中,钉仓可被构造成可拆除地存储其内的钉,砧座可被构造成使缝钉在从钉仓释放时变形。
在一些情形下,组织层可以相对较薄,具有高流体含量,和/或具有不均匀的厚度,这会使缝钉不适当地形成于组织中。为了改进这一问题,在组织被夹住并钉合时可使用一片支撑材料来支撑组织。在至少一个实施方式中,一片支撑材料在第一夹钳构件和第二夹钳构件插入外科手术部位之前可释放地连接到第一夹钳构件和第二夹钳构件中至少一个构件上。在各种实施例中,这片支撑材料可用于将砧座施加的压力分布在支撑材料的表面区域上,从而在组织内形成更均匀的组织压缩轮廓。在至少一个实施例中,均匀的组织压缩轮廓可以增加钉适当地形成于组织中的可能性。
在各种实施方式中,外科医生难以将支撑材料连接到端部执行器的夹钳构件上。在至少一个实施方式中,这片支撑材料可以使用粘合剂连接到其中一个夹钳构件上,所述粘合剂被构造成将支撑材料可释放地保持在其中一个夹钳构件上。在这种实施方式中,由于粘合剂可能立即将支撑材料粘结到夹钳组件上,外科医生必须小心地将支撑材料与夹钳构件对准。在这种情形下,这片支撑材料必须从夹钳构件去除,并替换一片新的支撑材料。因此,外科医生可能在将支撑材料放置和对准于端部执行器的夹钳构件上花费可观的时间。
发明内容
在本发明的至少一种形式中,外科器械的片支撑材料和/或端部执行器可以具有帮助外科医生或其他临床医生将片支撑材料适当地对准并连接到端部执行器的部件。在至少一个实施方式中,该片支撑材料可以包括至少一个从其延伸的构件,其中该构件可被构造成接合钉仓内限定的钉腔和/或砧座上限定的砧座凹窝中之一。在至少一个这种实施方式中,该构件可例如摩擦配合和/或压配合在钉仓和/或砧座凹窝内以将支撑材料可释放地保持在钉仓和砧座其中之一上。在各种实施方式中,凹槽或狭缝可限定于钉仓和/或砧座其中之一内,其中该凹槽可被构造成容纳片支撑材料的一部分并将该片支撑材料可释放地保持在那里。在至少一个实施方式中,片支撑材料可包括从其延伸的凸起,其中该凸起可被构造成可释放地接合钉仓和砧座至少其中之一上的切割构件通道。在这种实施方式中,该凸起可以压配合,摩擦配合和/或以其它方式接合通道。
在本发明的至少一种形式中,片支撑材料和端部执行器可包括协作件,例如唇缘,其允许这片支撑材料以卡扣配合的方式连接到端部执行器上。在各种实施方式中,端部执行器可包括从其延伸的弹性构件,其中该弹性构件可被构造成接触这片支撑材料的一部分并将这片支撑材料可释放地保持在端部执行器上。在至少一个实施方式中,钉仓和砧座其中之一可包括多个保持构件,其中片支撑构件的部分可摩擦配合地抵靠在保持构件上以将该片支撑材料可释放地保持在钉仓和砧座上。
在本发明的至少一种形式中,片支撑材料可释放地连接至套管,其中该套管可被构造成在端部执行器的钉仓和砧座至少其中之一上滑动。在至少一个实施方式中,该片支撑材料可以包括可连接到套管的侧部,和被构造成在钉从钉仓释放时接合缝钉的主体部分。在这种实施方式中,该侧部可用于将主体部分可释放地保持至套管。在至少一个实施方式中,例如这片支撑材料在侧部和主体部分可以限定有凹槽和/或穿孔,从而主体部分可与侧部隔开。因此,在至少一个实施方式中,该穿孔和/或凹槽能够允许套管在缝钉已经释放进入主体部分之后从支撑材料上移除。
在本发明的至少一种形式中,用于片支撑材料的包装件可用于将片支撑材料快速地对准并放置于端部执行器中。在各种实施方式中,包装件可包括第一部分、第二部分和能够可释放地连接至第一部分的支撑材料。在至少一个实施方式中,第二部分可被构造成在邻近片支撑材料的第一位置和第二位置之间移动。在各种实施方式中,该片支撑材料可在第二部分位于第二位置时露出,使包装件位于打开的端部执行器的夹钳构件之间,从而使露出的支撑材料接合端部执行器的夹钳构件。在各种实施方式中,支撑材料上可包括用于将支撑材料保持在夹钳构件其中一个上的粘合剂。在这片支撑材料接合其中一个夹钳组件之后,第二部分可被拉离端部执行器,从而将第一部从该片支撑材料释放出来。
在本发明的至少一种形式中,片支撑材料可固定至端部执行器的砧座和钉仓至少其中之一。在各种实施方式中,砧座和/或钉仓可包括一个或多个孔或开口,该孔或开口可被构造成容纳一个或多个紧固件以将片支撑材料保持至砧座或钉仓。在各种实施方式中,该紧固件可从砧座和/或钉仓上的孔释放出来,从而允许片支撑材料从端部执行器分离。该紧固件还可被构造成从该片支撑材料分离,并可包括可生物吸收材料,从而使其能够在患者身体内再吸收。在至少一个实施方式中,这片支撑材料可由一个或多个可分离的夹子连接到端部执行器。

在各种实施方式中,支撑材料上的未活化的粘合剂可由二元粘合剂(binary adhesive)的一种成分组成,而且反应剂可由二元粘合剂的另一成分组成,从而,当两种成分结合时,粘合剂被活化。用另一种方式来描述,该未活化的粘合剂可包括一种材料,所述材料在被引入如下所述的一反应剂前为无活性的。在至少一种实施方式中,该未活化的粘合剂和该反应剂例如可由一种适合外科手术的环氧树脂组成。在各种实施方式中,该未活化的粘合剂例如可包括抗水材料,使得该粘合剂被引入水中时可基本上不溶解和/或基本上不反应。在至少一种实施方式中,该粘合剂可包括如热熔粘合剂、硅树脂、氨基甲酸乙酯、氰基丙烯酸盐粘合剂、水凝胶和/或异氰酸酯(isocyanolate)、或任何合适的单体和/或聚合体。在各种实施方式中,可包括在如下专利文献中所公开的这些适当的粘合剂和连接装置:1993年11月23日公告的、题为“Method and apparatus for achieving hemostasis along astaple line(为实现沿钉合线止血的方法和装置)”的美国专利No.5,263,629;2003年12月2日公告的、题为“Device for attachment ofbuttress material to a surgical fastening device(用于将支撑材料连接到手术紧固装置的装置)”的美国专利No.6,656,193;2003年7月15日公告的、题为“Adhesive for attaching buttress material to a surgicalfastening device(用于将支撑材料连接到手术紧固装置的粘合剂)”的美国专利No.6,592,597;2001年8月14日公告的、题为“Surgicalbettress and surgical stapling apparatus(手术支撑和手术钉合装置)”的美国专利No.6,273,897;以及2003年9月30日提交的、题为“Apparatus and method for attaching a surgical buttress to a staplingapparatus(用于将支撑材料连接到钉合装置的装置和方法)”的美国专利申请No.10/674,303,上述文献的全部公开内容由此通过引用结合入本文。在各种实施方式中,反应剂可包括由有氧引发剂(aerobicinitiator)、厌氧引发剂(anaerobic initiator)、季铵盐(quaternaryammonium salt)或化合物和/或任何其他适合的游离基机理引发剂(radical mechanism initiator)如阴离子引发剂中的至少一种组成的材料,所述材料例如包括在2006年6月30日提交的、题为“Absorbablecyanoacrylate compositions(可吸收的氰基丙烯酸盐粘合剂合成物)”的美国专利申请No.11/479,424中公开的材料,上述专利申请的全部公开内容由此通过引用结合入本文。在各种实施方式中,可使用例如从科乐医药有限公司(Closure Medical Corporation)商业获得的粘合剂和/或反应剂。在至少一种实施方式中,粘合剂可通过紫外光或任何适合的光化学过程来被活化。几种这样的粘合剂例如可从亨凯尔公司(Henkel Loctite Corporation)商业获得。
接着上文,在各种实施方式中,在支撑材料片上使用未活化的或无活性的粘合剂可使外科医生能够将支撑材料片定位或重定位在砧面和/或钉仓的板上,而不需要将粘合剂立即粘接于其上。在至少一种实施方式中,未活化的粘合剂可在反应剂被应用于未活化的粘合剂之后才被粘接至面和/或板上。这个特征的非常有利之处在于,外科医生无需在第一次尝试时就将支撑材料片准确定位,而是能够将支撑材料片在板和/或面上进行定位和重定位,以确保支撑材料片与面和/或板准确安装和对准。在各种实施方式中,至少一个保持或对准构件如保持构件318(图23)例如在使用反应剂之前可被用于结合粘合剂/反应剂,来将支撑材料片保持在端部执行器的面和/或板上。
