摘要： Methods and devices are provided for effecting movement of one or more components of a multifire device, such as a clip applier, hernia tacker, or skin stapler. In one exemplary embodiment, a surgical fastening instrument is provided having an elongate shaft with an end effector coupled thereto and adapted to apply one or more surgical fasteners to tissue. An electrically expandable and contractible actuator, such as an electroactive polymer actuator, can be used to drive a fastener advancing or forming assembly through the elongate shaft, thereby driving a surgical fastener into tissue. In another embodiment, an electrically expandable and contractible actuator, such as an electroactive polymer actuator, can be used to effect movement of an articulation joint formed between the elongate shaft and the end effector.

摘要： Methods and devices are provided for controlling movement of a working end of a surgical device. In one embodiment, methods and devices are provided for moving an end effector on a distal end of a surgical fastening device. Movement can include rotational movement of the end effector about an axis of the shaft, articulation of the end effector relative to the shaft, and actuation of an end effector, e.g., closing, firing, and/or cutting. In other embodiments, a single cable actuator is provided and is movable between a first position, in which it is effective to rotate an end effector without actuating (i.e., closing and firing) the end effector, and a second position, in which it is effective to actuate the end effector without rotating the end effector. In other aspects, methods and devices are provided for moving a flexible neck formed on a distal end of an accessory channel for use with an endoscope. Movement of the flexible neck can be used to control positioning of a tool extending through the flexible neck.

摘要： A surgical instrument particular suited to endoscopic use is disclosed. Various embodiments include an end effector that is sized to be inserted through a trocar. An elongated shaft assembly is coupled to the end effector and a control handle. The elongated shaft assembly has a distal portion that is adjacent to said the effector for insertion into the trocar. The elongated shaft assembly further has a proximal portion that is remote from the distal portion such that the proximal portion protrudes from the trocar when the end effector and distal portion are inserted therethrough. The control handle is articulatably coupled to the proximal portion of said elongated shaft assembly to enable the surgeon to move the handle portion to a more ergonomically comfortable position while carrying out the endoscopic procedure. Various articulation joint embodiments and locking arrangements are disclosed.
