Abstract: A surgical instrument includes an elongated shaft and an end effector coupled to the shaft. The end effector includes a first member, a knife member, and a second member. The first member is movable towards a distal end of the end effector. The knife member is pivotally coupled to the first member. The second member is movable towards the distal end of the end effector. The knife member is configured to be in a cutting position during a translation of the first and second members towards the distal end of the end effector. The knife member is rotatable relative to the first member to stow the knife member into a non-cutting position after the translation of the first and second members towards the distal end of the end effector.

Abstract: A surgical instrument having an elongated shaft having a shaft distal end and a shaft proximal end. An end effector is coupled to the shaft distal end and includes opposed jaws. A housing is included in one of the jaws, the housing having a housing proximal end, a housing distal end, an upper surface, a distal garage having lateral surfaces that extend above the upper surface, and a plurality of staple openings extending through the upper surface. A knife member is supported within the housing for movement distally. The knife member is moveable into a predetermined parked position such that a first portion of the cutting blade displaces below the upper surface and a second portion remains displaced above the upper surface. There is enough lateral clearance in the predetermined parked position between the lateral faces and the second portion to accommodate a dislodged staple.

Abstract: The present disclosure provides a surgical instrument, such as a tissue sealing instrument, with an elongate shaft and an end effector. The end effector includes a first jaw and a second jaw that includes a staple cartridge with a plurality of staples for engaging tissue. The instrument further includes a drive member for closing the jaws and engaging the staples, and an actuation mechanism, such as a coil, in contact with the drive member. The actuation mechanism is configured to translate the drive member distally through the first jaw (instead of through the staple cartridge as in conventional surgical stapling instruments). Eliminating the internal channel for the actuation coil from the staple cartridge provides more space in the cartridge for the staples, allowing for the use of taller staples and/or a more compact and maneuverable instrument.

Abstract: A surgical instrument, such as a tissue sealing instrument, is provided with an end effector having first and second movable jaws that define a gap therebetween in the closed position for clamping, sealing and/or stapling tissue. The jaws are movable relative to each other in the closed position to reduce a thickness of least one portion of this gap. This configuration allows the jaws to be moved closer together to reduce the overall size of the instrument when, for example, the instrument is introduced and retracted through an opening in the patient, or maneuvered within a body cavity. The surgical instrument may also have multiple settings for use with different staple cartridges, while still maintaining a fixed dimension between the two jaws for clamping, stapling and/or sealing tissue, providing a more adaptable surgical instrument that allows the surgeon to use different staple cartridges without having to change surgical instruments.

Abstract: A surgical instrument with a stowing knife blade includes an elongated shaft, an end effector coupled to the shaft and including two opposed jaws, a housing included in one of the jaws, a first member mounted in the housing and movable distally, a knife pivotally coupled with the first member, and a second member. The knife is configured to cut when advanced distally. The first and second members are moved distally at the same rate during a cutting motion of the knife and the second member blocks a rotation of the knife relative to the first member during the cutting motion of the knife. After moving through the first distance, relative movement between the first and second members occurs so as to permit or induce the previously blocked rotation of the knife so that the knife can be stowed.
