    摘要: Various example embodiments described herein are directed to articulating surgical instruments for treating tissue comprising an end effector and a shaft extending proximally from the end effector along a longitudinal axis. In certain embodiments, the shaft comprises a plurality of transverse spacer members as well as first and second rotatable members extending through at least a portion of the plurality of transverse spacer members. The first and second rotatable members may both be biased away from the longitudinal axis such that their respective directions of bias vary with rotation of the first rotatable member. When the respective directions of bias of the first and second rotatable members oppose one another, the shaft may be substantially straight. When the respective directions of bias of the first and second rotatable members are aligned with one another, the shaft may articulate away from the longitudinal axis in the direction of the alignment.

    摘要: A bone cutting surgical instrument includes features to mitigate heat generation during use. Excessive heat can be detrimental to bone health as well as to the instrument itself. In one example a liquid dispensing feature provides a flow of cooling liquid to an ultrasonic blade via a lumen in a waveguide of the instrument. In another example, the blade has a serrated edge with a plurality of teeth arranged in a pattern to provide dimension and space during cutting actions. In another example, the blade has an oversize distal portion that creates an oversize slot when cutting to avoid excessive contact between the cut bone and proximal portions of the blade. In another example the blade includes an irrigation slot and also a micro slot in a distal end of the blade that connects with the irrigation slot.

    摘要: In various embodiments, a fastening assembly comprising a first jaw, a second jaw, a closure member, a rotatable drive shaft, a firing member, an electric motor, a sensing device, and a control system is disclosed. The second jaw is movable between an open position and a closed position relative to the first jaw. The closure member is movable between a first position and a second position. The second jaw is in the closed position when the closure member is in the second position. The electric motor is operable to rotate the rotatable drive shaft and advance the firing member through a firing stroke. The sensing device is configured to sense when the closure member is in the second position. The control system is configured to prevent advancement of the firing member through the firing stroke until after the second jaw is in the closed position.

    摘要: The present invention includes a surgical stapler having a staple cartridge, an anvil, and a cutting member having a cutting surface, wherein the cutting member is relatively movable with respect to the anvil and the staple cartridge. In at least one embodiment, one of the anvil and the staple cartridge defines a slot which is configured to receive at least a portion of the cutting member and guide the cutting member as it is moved relative to the anvil and the staple cartridge. In these embodiments, the slot can define a path having linear and/or curved portions. In various embodiments, the path can include a curved portion having a first portion that extends away from the shaft axis and a second portion that extends toward the axis. In one embodiment, the path can include a curved portion defined by an arc corresponding to an angle greater than 90 degrees.

    摘要: A stapling assembly comprising a proximal end, a distal end, a first jaw, a second jaw, a staple cartridge, a first motor-driven system, and a second motor-driven system is disclosed. The first jaw comprises a first bottom surface. The second iaw is rotatably coupled to the first iaw about a pivot and is movable between an unclamped position and a fully-clamped position. The second jaw comprises a second bottom surface. The staple cartridge comprises a plurality of staples removably stored therein. The first motor-driven system is configured to engage the second bottom surface of the second iaw to move the second iaw toward the fully-clamped position. The second motor-driven system is configured to engage the second jaw and the first bottom surface of the first jaw and hold the second jaw in the fully-clamped position. The second motor-driven system is actuatable after the first motor-driven system has been actuated.

    摘要: A stapling system comprising an end effector, a staple cartridge, a rigid shaft, an articulation joint, an articulation system, a clamping member, and a firing system comprising a sled movable within the staple cartridge to eject staples from the staple cartridge during a staple firing stroke, an electric motor, and a firing actuator is disclosed. The end effector comprises a first jaw and a second jaw rotatable relative to the first jaw between an unclamped position and a clamped position. The clamping member is configured to rotate the second iaw into the clamped position. The stapling system further comprises a system responsive to the clamping of the second iaw which enables the staple firing stroke to be performed after the second jaw has been rotated into the clamped position, and a system configured to maintain an orientation of the end effector about the articulation joint during the staple firing stroke.
