摘要： A surgical instrument particularly suited to endoscopic articulates an end effector by including an end effector having a geared articulation mechanism that converts rotational motion from a handle portion. A hollow articulation drive tube transfers the rotation motion in some versions to a spear gear, bevel gear or snaggle tooth gear articulation mechanism. Alternatively, one or more threaded drive rod offset from a longitudinal axis engages a worm gear or flex-neck articulation mechanism.

摘要： A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A firing member reciprocates within an elongate shaft to the end effector to transfer this firing motion. A retraction spring retracts the firing member after full firing. Between firing strokes as the firing trigger is released, an anti-backup mechanism activates an electrical actuator (e.g., elecroactive polymer actuator) that is physically grounded to the handle to bind the firing member preventing inadvertent retraction.

摘要： A surgical stapling and severing instrument enables minimally invasive surgical procedures by having upper and lower jaws (i.e., anvil and staple channel) that are positioned with an elongate shaft and handle through surgical openings, and in particular through a cannula of a trocar. A pair of fluid actuator bladders (lift bags) are positioned in the staple channel beneath a proximally projecting lever tray so that transfer of fluid from the handle causes closing and clamping of the anvil. The bi-directional fluid control may be mechanically produced at the handle or by activating an electroactive polymer actuator. Once firing is sensed, an EAP plunger in a medical substance syringe inserted into the elongate shaft is activated to dispense a medical substance (e.g., anesthetics, adhesives, cauterizing substances, antibiotics, etc.) and is guided along a firing bar to a cutting surface of an E-beam placing the substance on tissue as severed.

摘要： A surgical instrument for laparoscopic and endoscopic clinical procedures simultaneously severs and staples tissue clamped in an end effector comprising an elongate channel, which holds a staple cartridge, and a pivotally attached anvil. An E-beam firing bar engages the channel and selectively engages the anvil during distal firing movements, wherein the tissue is severed and stapled driven upward from the staple cartridge to form against the anvil. In particular, a wedge integral to the staple cartridge is driven distally by a middle pin of the firing bar to effect stapling. A single lockout of the elongate channel responds to the presence of the wedge sled in its unfired position to allow the firing bar to fire. Otherwise, the single lockout prevents firing when the staple cartridge is missing or spent.

摘要： A surgical instrument particularly suited to endoscopic use articulates an end effector by including a fluid transfer articulation mechanism that is proximally controlled. A fluid control, which is attached to a proximal portion, transfers fluid through the elongate shaft through a first fluid passage to a first fluid actuator that responds by articulating an articulation joint. Two opposing fluid actuators may respond to differential fluid transfer to effect articulation. Thereby, design flexibility is achieved by avoiding the design constraints of transferring a mechanical motion through the tight confines of the elongate shaft sufficient to effect articulation.

摘要： A surgical stapling and severing instrument particularly suited to endoscopic articulates an end effector by having a geared articulation mechanism that converts rotational motion from a handle portion. A firing bar longitudinally translates between the handle portion and the end effector. The firing bar head is thickened in order to present an undistorted cutting edge and engagement features to the opposing jaws of the end effector. The firing bar also advantageously includes a thinned or tapered proximal portion in the form of a strip or band that negotiates the articulation mechanism flexibility. To prevent buckling of the firing bar strip during firing, a pair of support plates adjustably flank the firing bar strip through the articulation mechanism. Various versions show resilient and spring engagement of each end of the support plate to distal and proximal sides of the articulation mechanism, as well as a resilient support plate.

摘要： An articulating surgical instrument suited for endoscopic use includes a lateral articulation control into a handle portion that provides an intuitive visual and tactile indication to the clinician as to the amount and direction of articulation of an end effector at a distal end of a shaft. Lateral movement of a lateral control actuator is converted into a longitudinal motion or a rotational motion transferred by the shaft to an articulation mechanism. A version of a lateral articulation control for a rotationally driven articulation mechanism incorporates an articulation backdrive lockout that prevents forces on the end effector from causing the selected amount of articulation from being changed.

摘要： A surgical stapling and severing instrument particularly suited to endoscopic use includes a proximal portion that is manipulated external to a patient to position an attached elongate shaft and end effector to a desired surgical site inside of the patient. An articulation joint pivotally attaches the end effector to the elongate shaft to give further clinical flexibility in reaching tissue at a desired angle. A closure tube assembly includes a multiple pivoting portion that overrides the articulation joint in order to distally translate to close the end effector yet pass over an articulated shaft. Thereby, additional clinical flexibility in positioning the end effector is achieved without losing the ability for separate closure and firing motions transferred by the shaft. Thereby, design flexibility is achieved by avoiding the design constraints of transferring a mechanical motion through the tight confines of the elongate shaft sufficient to effect articulation.
