可递送式外科器械
摘要：
在各种实施方案中，本发明公开了一种无轴端部执行器。该端部执行器可包括砧座组件，该砧座组件包括钉成形表面。该端部执行器还可包括钉仓通道，该钉仓通道被构造成能够在其中接收钉仓。该端部执行器可包括被构造成能够闭合砧座的闭合系统。在各种实例中，该闭合系统还可使容纳在钉仓内的钉成形。该端部执行器还可包括切割构件，该切割构件被构造成能够切割定位在砧座与钉仓之间的组织。在各种实例中，该切割构件可由闭合系统致动。在其他实例中，该端部执行器可包括用于致动切割构件的独立系统。在各种实例中，该端部执行器能够通过套管针被递送到手术部位，然后通过组装到端部执行器的一个或多个致动器来操作。
摘要（英）：

In various embodiments, a shaftless end effector is disclosed. The end effector can comprise an anvil assembly including a staple forming surface. The end effector can also comprise a staple cartridge channel configured to receive a staple cartridge therein. The end effector can include a closure system configured to close the anvil. In various instances, the closure system can also form the staples contained within the staple cartridge. The end effector can also include a cutting member configured to cut tissue positioned intermediate the anvil and the staple cartridge. In various instances, the cutting member can be actuated by the closure system. In other instances, the end effector can include an independent system for actuating the cutting member. In various instances, the end effector can be delivered to a surgical site through a trocar and then operated by one or more actuators that are assembled to the end effector.
