Abstract: A surgical instrument comprising a surgical end effector that comprises a first jaw and a second jaw that is movably supported relative to the first jaw for selective movement between an open position and closed positions. The surgical instrument further comprises a closure member that is axially movable in response to closing and opening motions. The closure member comprises at least one opening cam that protrudes therefrom to movably engage a corresponding cam surface on the second jaw such that upon application of the opening motion, the at least one opening cam movably engages the corresponding cam surface to move the second jaw to an open position, even when the jaws are under a load.

IPC: A61B17/072

Abstract: A surgical stapling assembly is disclosed. The surgical stapling assembly can include a first jaw, a second jaw, an articulation joint, a closure drive comprising a first flexible rotary drive extending through the articulation joint, and a firing drive comprising a second flexible rotary drive extending through the articulation joint and rotatable independent of the first flexible rotary drive. The surgical stapling assembly can further include a 3D-printed component. The surgical stapling assembly can be configured to form different staple shapes, such as non-planar staples and planar staples, can include an eccentrically-driven firing assembly, and/or can include a floatable component. The surgical stapling assembly can include a staple cartridge including a longitudinal support beam.

Abstract: A surgical device having at least one rotary input screw in the end effector is provided. A rotary input screw can extend through a central longitudinal portion of the end effector. The end effector can include an improved closure system, firing systems, leveraging and alignment features between the staple cartridge and the surgical device, staple cartridges having multi-staple drivers, single-firing knifes and lockout/safety features for the same, and/or modified staple patterns, for example. Certain components can be 3D-printed components.

Abstract: Surgical instruments having a rotary drive that can selectively actuate multiple end effector functions are described herein. In at least one embodiment, a surgical instrument includes an outer shaft, an end effector coupled to the outer shaft, a rotatable drive shaft coaxially disposed within an inner lumen of the outer shaft, and a plurality of selectively engageable clutches configured to transfer torque from the rotatable drive shaft to the end effector. Each of the clutches is configured to convert the rotation of the drive shaft into one of a plurality of movements of the end effector relative to the outer shaft.

Abstract: A surgical stapling instrument comprising an elongate shaft assembly that defines a shaft axis and includes a surgical end effector that is operably coupled thereto by an articulation joint. The surgical instrument includes a longitudinally movable flexible firing beam that is configured to flexibly traverse the articulation joint and be selectively axially movable from a starting position to an ending position. A middle support member is movably coupled to the elongate shaft assembly and a portion of the surgical end effector. A proximal support link is located proximal to the middle support member and is configured to provide lateral support to a proximal portion of the flexible firing beam traversing the articulation joint. A distal support link is located distal to the middle support member and is configured to provide lateral support to a distal portion of the flexible support beam traversing the articulation joint.
