一种一次性加载装置。该一次性加载装置包括：外壳组件；刀片组件，连接到所述外壳组件上；以及试剂筒，连接到所述外壳组件上。所述试剂筒装纳医疗试剂。所述一次性加载装置将医疗试剂输送到邻近切割表面，其中切割表面包含在所述刀片组件中。
Description
技术领域
本发明在各实施例中总的涉及一种一次性加载装置，该装置可用于与可多次使用的外科器械连接，本发明还涉及包括所述一次性加载装置的外科器械。
背景技术
用于同时在组织中开纵向切口和在切口的相对两侧施加多排缝钉的外科器械在现有技术是已知的。该组织可以例如包括人类组织、动物组织、膜或者其他器官。这种外科器械通常包括一对相对的夹钳构件，该对夹钳构件相配合以握持或者夹钳其间的组织，该外科器械还包括切割表面，用于形成切口。当用于内窥镜或腹腔镜时，该对夹钳构件能够穿过插管通道。夹钳构件中的一个通常支撑钉仓，该钉仓具有至少两排横向间隔开的缝钉以及与所述缝钉对准的推动器。另一个夹钳构件可在打开位置和闭合位置之间运动，并且限定了一砧座，该砧座具有与钉仓中的多排缝钉相应对准的缝钉形成袋。这种器械还可包括楔形件，该楔形件被驱动时，依次接触推动器，以朝着砧座和穿过组织击发缝钉。
这种动作对组织产生的损伤可能很明显。总之，对损伤的组织部位输送足量的医疗试剂，促进切口的适当愈合，减少感染的可能性，和/或明显改进康复过程。医疗试剂施加到受损组织部位，通常是通过与形成切口和施加缝钉的外科器械不同的装置实现的。这种装置通常增加了手术的并发症和成本。但是，这种装置通常是必须的，因为用于同时在组织中开纵向切口和施加缝钉的外科器械不能存储和输送足量的医疗试剂到受损组织部位，通过这种外科器械输送医疗试剂到受损组织部位会使该医疗器械不能再次使用。

图8所示一次性加载装置10的一部分的放大图。
图11示意性显示出一次性加载装置10的各种实施例。为清楚起见，没有显示出一次性加载装置10的某些部分。所示部件相对于通道26的总体位置表示这些部件在击发构件26推进之前的位置(例如预击发位置)。如图11所示，砧座组件24处于闭合位置，刀片组件20、砧座组件24、第一医疗试剂驱动器168、驱动块172以及锁定构件的击发后位置与它们相对于通道26的预击发位置不同。
图12示意性显示出一次性加载装置的各种实施例，图12是图11所示一次性加载装置10的一部分的放大图。如图12所示，第一医疗试剂驱动器168的击发后位置与第一分配口96之间间隔一定距离。同样，第二医疗试剂驱动器170的击发后位置与第二分配口102之间间隔一定距离。
图13示意性显示出一次性加载装置10的各种实施例。为清楚起见，没有显示出一次性加载装置10的某些部分。图13与图4类似，但显示出了试剂筒18的主体86的第一部分88，还显示出了实施为电活化聚合物的第一医疗试剂驱动器168。图13还显示出了导体184，将第一医疗试剂驱动器168与触点174电连接。所示部件相对于通道26的总体位置表示这些部件在击发构件26推进之前的位置(例如预击发位置)。
图14示意性显示出一次性加载装置10的各种实施例。为清楚起见，没有显示出一次性加载装置10的某些部分。图14与图8类似，但是显示出了实施为电活化聚合物的第一医疗试剂驱动器168。图13还显示出了触点174和导体184，该导体184将触点174与第一医疗试剂驱动器168电连接。所示部件相对于通道26的总体位置表示这些部件在击发构件26推进之前的位置(例如预击发位置)。
图15示意性显示出外科器械200的各种实施例。外科器械200包括手柄组件202、连接到手柄组件202上的细长主体204以及可释放地连接到细长主体204上的一次性加载装置10。一次性加载装置10以任意方式连接到细长主体204上。例如，一次性加载装置10
通过上述连接桩74而可释放地连接到细长主体204上。手柄组件202和细长主体204可以类似于本领域公知的其他手柄组件和细长主体。例如，手柄组件202可以包括用于推进由细长主体204环绕的击发构件的部件，该击发构件推进一次性加载装置10的驱动块172。
在操作中，当击发构件推进时，击发构件的推进使驱动块172朝着一次性加载装置10的第二端部14推进。当驱动块172推进时，刀片组件20朝着一次性加载装置10的第二端部14推进。刀片组件20的推进使砧销166与砧体154配合，将砧座组件24朝着闭合位置推动。刀片组件20的推进还使滑块180朝着一次性加载装置10的第二端部14推进。当滑块180推进时，滑块180的倾斜前缘顺序地接触支撑在钉仓22中的推动器，使推动器以已知的方式从钉仓22推动外科紧固件。
根据第一和第二医疗试剂驱动器168、170连接到刀片组件20的实施例，驱动块172的推进使第一和第二医疗试剂驱动器168、170在主体86的第一和第二部分88、90中朝着试剂筒18的第二端部84推进。当第一和第二医疗试剂驱动器168、170推进时，它们与第一和第二密封构件104、106接触，并且推动第一和第二医疗试剂离开第一和第二分配口96、102。由于第一和第二医疗试剂驱动器168、170与第一和第二分配口96、102间隔一定距离，在第一和第二医疗试剂驱动器168、170从其预击发位置推进到击发后位置之后，一些医疗试剂仍然保持容纳在试剂筒18中。
根据第一和第二医疗试剂驱动器168、170是电活化聚合物的实施例，击发构件的推进使其与触点74电连接，使得电压施加到第一和第二医疗试剂驱动器168、170上。响应于所施加的电压，第一和第二医疗试剂驱动器168、170在试剂筒18的主体86的第一和第二部分88、90中扩张，并且推动第一和第二医疗试剂离开第一和第二分配口96、102。
当第一突起94和第二突起100用作挡块限制第一和第二医疗试剂沿着沟槽128、130朝着一次性加载装置10的第一端部12流动时，
被推动离开第一和第二分配口96、102的医疗试剂沿着相应的沟槽128、130朝着一次性加载装置10切割表面114推进。当刀片组件20沿着由钉仓22限定的狭槽142推进时，钉仓22还将医疗试剂保持在沟槽128、130中，直到医疗试剂离开沟槽128、130，邻近切割表面114。医疗试剂因此有效地输送到切割和缝合部位。
单次使用之后，将一次性加载装置10从细长主体204去除，并用另一个一次性加载装置10替换再次使用。该过程可以重复多次。因此，手柄组件202和连接到其上的细长主体204可以使用多次。
尽管已经描述了各个实施例，但是应当理解，在保持本发明的一些或全部优点的情况下，本领域的技术人员可以进行各种修改、变型和改变。例如，根据各实施例，单个元件可以替换成多个元件，多个元件可以替换成单个元件，以执行给定的功能。因此本申请旨在覆盖所有这些修改、变型和改变，而不背离后附权利要求书公开的范围和精神。
