A surgical device for clipping tissue is disclosed. The surgical device comprises a clip magazine comprising a plurality of clips, an end effector movable between an open position and a closed position, and a jaw actuator operably responsive to a first rotatable input. The jaw actuator is configured to move the end effector between the open position and the closed position. The surgical device further comprises a reciprocating feeder drive and a controller. The reciprocating feeder drive is operably responsive to a second rotatable input. The controller is configured to advance a clip from the clip magazine into the end effector by way of the feeder drive when the end effector is in the open configuration. The controller is further configured to actuate the jaw actuator to move the first jaw and the second jaw toward the closed position without advancing a clip into the end effector.

A stapling assembly comprising a first jaw, a second jaw, an elongate channel configured to receive a staple cartridge, a firing member configured to perform a firing stroke, a biasing element, and a rotary drive shaft is disclosed. The staple cartridge comprises staple cavities, staples, staple drivers, and a sled. The firing member comprises a cutting edge, a first camming member, and a second camming member. The biasing element comprises a spring and is movable between an initial position and a displaced position. The rotary drive shaft is movable between a first position and a second position relative to the elongate channel. The rotary drive shaft is moved from the first position to the second position by the staple cartridge when the staple cartridge is inserted into the elongate channel and moves the biasing element to the displaced position against a distal biasing force of the spring.

A system for performing an endoscopic procedure is provided. The system includes an actuation assembly having a handle assembly and a shaft assembly. The system also includes an end effector configured for selective and operative connection to a distal end of the shaft assembly. The system further includes a holder for selectively engaging the end effector and facilitating attachment of the end effector to the shaft assembly.

Medical systems, devices and methods are provided for engaging tissue, e.g. for clipping tissue, closing a perforation or performing hemostasis. Generally, the medical system including a housing, first and second jaws rotatable relative to the housing, a driver, and an elongate drive wire. The elongate drive wire may be disconnected from the driver, first and second jaws, and the housing, which are left in vivo engaged with the tissue.

In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.

Devices, systems, and methods for providing remote traction to tissue may include a grasper and a control element. The grasper may have a first jaw, a second jaw, a main body, and a first magnetic element. The control element may include a second magnetic element. The first and second magnetic elements may attract the grasper to the control element such that the grasper is oriented parallel, perpendicularly, or at an angle between parallel and perpendicular with respect to the control element and/or a body. In some instances, the grasper may include first and second magnetic elements and the control element may include third and fourth magnetic elements.

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 a shaft, an end effector coupled to the shaft, a rotatable drive shaft coaxially disposed within an inner lumen of the 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.

A surgical instrument is disclosed comprising a shaft, an end effector, and an articulation joint rotatably connecting the end effector to the shaft. The surgical instrument further comprises an articulation drive system configured to permit high degrees of articulation.

A needle carrier (100) includes a pinching attachment (20) having a pinching arm member and a pinching arm support portion on which the pinching arm member is disposed and configured to pivotably support the pinching arm member around a first axis line, a needle carrier body (10) on which a grip portion (112) is formed, a pinching arm opening/closing drive portion (30) having a pinching operation lever (31) and a pinching operation transmission part, and a pinching arm pivotal drive portion (40) having a pivotal operation wheel (41) and a pivotal operation transmission part, and the pinching arm opening/closing drive portion (30) includes an axial dimension expansion/contraction spring (35) configured to attenuate a pinching operating force input from the pinching operation lever (31) and pinch the pinching portions.
