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 3D-printed component can include a plastic body and one or more metal substrates with interlocking features embedded in the plastic body. The surgical stapling assembly can include a firing member having a flexible portion configured to flex more readily that adjacent portions of the firing member.

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.

Abstract: Disclosed is a method of controlling a modular battery powered handheld surgical instrument. The surgical instrument including a battery, a user input sensor, a controller, a radio frequency (RF) drive circuit, an ultrasonic transducer, ultrasonic transducer drive circuit, and an end effector. The end effector including an electrode electrically coupled to RF drive circuit, an ultrasonic blade acoustically coupled to the ultrasonic transducer, and a sensor to measure tissue parameters. The method includes applying an RF current drive signal to the electrode by the RF drive circuit; applying an ultrasonic drive signal to the ultrasonic transducer by the ultrasonic transducer drive circuit to acoustically excite the ultrasonic blade; controlling intensity, wave shape, and/or frequency of the RF current drive signal and the ultrasonic drive signal on a sensed measure of a tissue or user parameter.

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.

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.
