摘要： The surgical instrument system disclosed is particularly useful for endoscopic procedures. In the preferred embodiment, a hemostatic clip applicator can be directly connected to a trigger assembly or indirectly connected to the trigger assembly through the use of an extension. The connection between the extension and the clip applicator is secured to prevent accidental release during the procedure. The applicator receives a longitudinal input and translates the input into relative component motion through the use of gearing to apply the clips. The handle stem assembly in an alternative embodiment has a drive rod configuration that connects to a closure member so as not only to provide the distal biasing force, but also to provide, if needed, a proximal pulling force to assist in release of the jaw if it becomes necessary.
摘要翻译：所公开的手术器械系统对于内窥镜手术是特别有用的。在优选实施例中，止血夹施加器可以直接连接到触发器组件，或者通过使用延伸件间接连接到触发器组件。延伸件和夹子施加器之间的连接是固定的，以防止在过程中意外释放。施加器接收纵向输入，并通过使用传动装置将输入转换成相对分量运动以施加夹子。在替代实施例中的手柄柄组件具有驱动杆构造，其连接到闭合构件，以便不仅提供远侧偏压力，而且还可以在需要时提供近侧拉力以帮助释放夹爪，如果这是必要的。

摘要： The present invention provides a means for applying a substantially constant force to move clips in queue within an applicator, as well as means for more effectively dispensing the endmost clip from a column of abrasive clips within an applicator. The constant force means generally comprises a constant force spring which is movably secured at both ends within a chamber in the applicator such that the pressure exerted between the ends of the constant force spring forces the clips in queue toward the jaws of the applicator. The dispensing means generally comprises a spring that applies sufficient pressure against the endmost clip in a column of abrasive clips to dispense the endmost clip from the column while preventing the next endmost clip from being dispensed until after the endmost clip has been forced into the jaws of the applicator and applied.
摘要翻译：本发明提供了一种用于施加基本恒定的力以在施放器内队列移动夹子的装置，以及用于更有效地从施用器内的研磨夹具柱分配最终夹子的装置。恒力装置通常包括恒定力弹簧，其恒定力弹簧可移动地固定在施加器中的腔室内的两端，使得施加在恒力弹簧的端部之间的压力迫使夹子朝向施用器的钳口排队。分配装置通常包括弹簧，该弹簧对研磨夹具柱中的最终夹子施加足够的压力，以从柱子中分配最终的夹子，同时防止下一个最近的夹子被分配，直到最后的夹子被迫进入涂抹器并涂抹。
