An assembly for fastening tissue is disclosed. The assembly may comprise a first jaw comprising a cartridge, wherein the cartridge comprises a plurality of fasteners. The plurality of fasteners comprises a first fastener comprising a first height and a second fastener comprising a second height, wherein the second height is different than the first height. The assembly further comprises a second jaw, wherein at least one of the first jaw and the second jaw is movable relative to the other. The second jaw comprises a plurality of fastener-engaging portions. The plurality of fastener-engaging portions comprises a first fastener-engaging portion and a second fastener-engaging portion. The assembly further comprises a compressible layer intermediate the first jaw and the second jaw.
ACTUATOR SUPPORT STRUCTURE FOR SURGICAL STAPLER
A surgical stapler includes first and second elongate members, a clamp member, and a firing assembly. The second elongate member is configured to receive a staple cartridge. The clamp member is operable to releasably clamp the first elongate member against the second elongate member. The firing assembly is translatable to fire the staple cartridge. The firing assembly includes a slider and an actuator configured to be selectively actuated by a user. The slider includes inner and outer engagement features. The actuator includes inner and outer engagement features. The inner engagement feature of the actuator is configured to engage with the inner engagement feature of the slider at a first interface when the actuator moves relative to the slider. The outer engagement feature of the actuator is configured to engage the outer engagement feature of the slider at a second interface when the actuator moves relative to the slider.
SURGICAL STAPLING APPARATUS WITH ADJUSTABLE HEIGHT CLAMPING MEMBER
A surgical stapling device includes a jaw assembly including a first jaw supporting an anvil assembly and a second jaw supporting a cartridge assembly. A drive assembly is translatable through the jaw assembly to effect the clamping and stapling of tissue. The drive assembly includes a clamping member and an adjustment member. The clamping member includes a first clamping surface configured to engage the anvil assembly. The adjustment member includes a second clamping surface configured to engage the staple cartridge. The first clamping surface is spaced from the second clamping surface to define a clamping height. The adjustment member is moveable relative to the clamping member between a first position and a second position to change the clamping height.
PREDICTION OF HEMOSTASIS ISSUES BASED ON BIOMARKER MONITORING
A computing system may predict a complication based on measurements of related biomarker(s) obtained via one or more sensing systems, and generate an adjustment of a surgical parameter associated with a surgery. The biomarker measurements may include pre-surgical and/or in-surgical measurements. The hemostasis-related biomarker(s) measured pre-surgery may include blood pressure, blood pH, edema, heart rate, blood perfusion rate, coagulation status and/or the like. Based on the prediction, the computing system may generate a control signal configured to alter a matter in which a surgical cutting and stapling device and/or a surgical energy operate, to adjust a surgical procedure plan, to adjust to a surgical instrument selection, indicate a probability of the hemostasis complication, and/or to indicate a suggested adjustment to surgical procedure plan, surgical approach, and/or surgical instrument selection.
Adhesive film laminate
A surgical stapler, or fastening instrument, may generally comprise a layer, such as a tissue thickness compensator, for example, releasably attached to a fastener cartridge and/or anvil by a flowable attachment portion. The flowable attachment portion may be indefinitely flowable. The flowable attachment portion may be flowable from the time that layer is installed to the fastener cartridge to the time in which the layer is implanted to patient tissue. The flowable attachment portion may comprise a pressure sensitive adhesive. The flowable attachment portion may comprise an adhesive laminate comprising a base layer comprising the tissue thickness compensator and an adhesive layer on at least a portion of a surface of the base layer comprising the pressure sensitive adhesive. Articles of manufacture comprising flowable attachment portion and methods of making and using the flowable attachment portion are also described.
Powered surgical stapler
A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.
SURGICAL STAPLING DEVICE WITH FLOATING STAPLE CARTRIDGE
A surgical stapling device includes tool assembly having an anvil assembly and a cartridge assembly including a cartridge channel and a staple cartridge supported within the cartridge channel. The cartridge channel has a pair of spaced sidewalls and a bottom wall. The cartridge assembly includes compression strips that are supported on upper edges of the side walls and are positioned to support the staple cartridge. In embodiments, each of the compression strips includes a connecting portion and the upper edge of each of the side walls defines a slot that is configured to receive the connecting portion of a respective compression strip to secure the compression strip to the side wall of the cartridge channel. In some embodiments, the tool assembly also includes a compressible pad that is supported on the bottom wall of the cartridge channel between the bottom of the cartridge channel and the staple cartridge.
SURGICAL STAPLER CARTRIDGE RETAINER WITH EJECTOR FEATURE
An apparatus includes an elongate body, at least one latch member, and a cartridge removal feature. The elongate body is sized and shaped to correspond with a deck of a surgical staple cartridge such that the elongate body is configured to cover a plurality of staple apertures of the surgical staple cartridge. The at least one latch member is configured to removably secure the elongate body to the surgical staple cartridge. The cartridge removal feature is integral with the elongate body. The cartridge removal feature defines a gap that is configured to receive a portion of the surgical staple cartridge. The cartridge removal feature is further operable to remove the surgical staple cartridge from a surgical stapler.
END EFFECTORS, SURGICAL STAPLING DEVICES, AND METHODS OF USING SAME
An end effector for a medical device includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket and a second staple pocket, each defined by the anvil face. The first staple pocket includes a first surface having a first depth, and the second staple pocket includes a second surface having a second depth. The cartridge has a first staple having a first height in an open configuration, a first driver, a second staple having a second height in an open configuration, and a second driver. A first staple formation distance is defined by a first distance between the first driver and the first surface of the first staple pocket when the anvil and the cartridge are in a closed position. The first staple formation distance differs from a second staple formation distance.
