    摘要： A surgical instrument that has an elongate channel assembly configured to operably support a staple cartridge therein. An anvil assembly may be movably and detachably coupled to the elongate channel assembly. In various embodiments, the anvil assembly may have a pair of trunnions pivotally received in open-ended slots in the elongate channel assembly. The trunnions may be retained in the opened ended slots by a selectively movable trunnion retention bar or by a closure member configured to apply a closing motion to the anvil. In other embodiments, a knife assembly may be supported within the elongate channel assembly for axial travel therein. The knife assembly may be provided with a detachable pin that is configured to ride in a slot in the anvil as the knife assembly is driven in the elongate channel assembly to draw the anvil assembly toward the elongate channel assembly. The pin is configured to be detached from the knife assembly to enable the anvil assembly to be detached therefrom.

    摘要： A surgical instrument including a drive mechanism configured to advance a staple driver and/or cutting member at a first rate and retract the staple driver and/or cutting member at a different rate. In at least one embodiment, the rate at which the driver and cutting member is advanced and/or retracted is the distance that the driver and/or cutting member is translated per actuation of a trigger, for example. In various embodiments, the cutting member can be retracted at a faster rate as compared to the rate in which it is advanced. In such embodiments, the surgical instrument can, owing to the slower advancing rate, provide a greater torque or advancing force to the cutting member while, owing to the faster retracting rate, reduce the time required for the surgeon to retract the cutting member.

    摘要翻译： 一种手术器械，包括驱动机构，其构造成以第一速率推进缝钉驱动器和/或切割构件，并以不同的速率使钉驱动器和/或切割构件缩回。 在至少一个实施例中，例如，驱动器和切割构件前进和/或缩回的速率是驾驶员和/或切割构件按照触发器的致动而平移的距离。 在各种实施例中，与其前进的速率相比，切割构件可以以更快的速度缩回。 在这样的实施例中，由于较慢的推进速率，手术器械可以向切割构件提供更大的扭矩或推进力，同时由于更快的收缩速度，外科医生缩短了切割构件所需的时间。

    摘要： A surgical instrument including a switching mechanism which allows a surgeon to selectively advance or retract a staple driver, cutting member, and/or other movable member within a staple cartridge. In various embodiments, the surgical instrument can include a handle, a trigger operatively coupled to the handle, a firing drive, and an end effector. In at least one embodiment, the trigger can be configured to slide between a first position in which an operation of the trigger can advance the movable member at a first rate and a second position in which an operation of the trigger can retract the movable member at a second rate.

    摘要： A surgical instrument including a switching mechanism which allows a surgeon to selectively advance or retract a staple driver and/or cutting member within a staple cartridge. In various embodiments, the surgical instrument can include a handle, a trigger operatively coupled to the handle, a firing drive, and an end effector. The firing drive can include a first ratchet assembly configured to advance a cutting member in the end effector and a second ratchet assembly configured to retract the cutting member. The trigger can include first and second pawls pivotably mounted thereon which are configured to be selectively engaged with the first and second ratchet assemblies, respectively. In at least one embodiment, the trigger can be configured to slide between a first position in which the first pawl is engaged with the first ratchet assembly and a second position in which the second pawl is engaged with the second ratchet assembly.
