摘要:
A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a removable cartridge. The cartridge includes a housing, a plurality of staples disposed in the housing, a deck disposed over the plurality of staples, and a fastener insert tip including a plurality of hooks. The deck defines apertures, with each aperture being substantially disposed over each staple. The instrument includes a fastener insert including hooks, and the fastener insert is removably received in the anvil. A buttress is attached to one or both of the anvil and the cartridge via the hooks.

A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a cartridge when in an open position. The cartridge includes a housing, a plurality of staples disposed in the housing, and a deck disposed over the plurality of staples. The deck defines apertures, with each aperture being substantially disposed over each staple. The cartridge further receives a matrix including glue beads suspended in the matrix. The staples are driven through the matrix to secure the matrix to tissue. The glue beads are activated when the matrix is secured to the tissue, such that the activated adhesive further secures the staple line in the tissue.

In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that comprises a handpiece housing that rotatably supports an ultrasonic transducer assembly therein that may be selectively rotated by a motor housed therein. Various forms of blades are disclosed for attachment to the ultrasonic transducer assembly such that the blade may be selectively rotatable within a hollow outer sheath. The hollow outer sheath has at least one opening therein through which the blade tip may be exposed to tissue. Vacuum may be applied to the cutting implement or through the outer sheath to draw tissue through the opening(s) in the sheath and into contact with a portion of the blade.
