摘要:
A surgical fastening instrument (100) including a handle portion (160), an elongated portion (120), an end effector and a clamp (200) is disclosed. The elongated portion (120) extends distally from the handle portion (160). The end effector includes a pair of jaws having a tissue contacting surface (202c) disposed substantially transverse to the longitudinal axis of the elongated portion (120). The end effector is disposed adjacent a distal end of the elongated portion (120), and at least one of the jaw members is movable with respect to the other between an open position and an approximated position for engaging body tissue therebetween. The clamp (200) has a clamping surface (220c) extending substantially transversely from an elongated member and has a height exceeding a height of the elongated member to extend adjacent a side surface of the jaw containing the plurality of fasteners (300a,300b). The clamp (200) is movable from a proximal position to a distal position for engaging body tissue.

A surgical instrument is disclosed. The surgical instrument includes a handle assembly, a drive assembly, an endoscopic portion, a pair of jaw members, a dynamic clamping member (606), and a tissue stop (700). The drive assembly is disposed in mechanical cooperation with a movable handle of the handle assembly. The endoscopic portion defines a first longitudinal axis. The jaw members are each longitudinally curved with respect to the longitudinal axis. The dynamic clamping member (606) is disposed in mechanical cooperation with a distal portion of the drive assembly and includes an upper beam, a lower beam, and a vertical beam having a cutting edge on a distal portion thereof. At least a portion of the dynamic clamping member (606) is longitudinally curved with respect to the longitudinal axis. The tissue stop (700) is disposed adjacent a distal portion of the first jaw member and configured to impede tissue from distally escaping the jaw members.

An attachable clamp for use with a surgical instrument is disclosed. The attachable clamp comprises a body portion, a first jaw member, a second jaw member and an actuation mechanism. The body portion defines a longitudinal axis and has attachment members configured to attach to an elongate portion of a surgical instrument. Each of the first jaw member and second jaw member extends distally from the body portion. The actuation mechanism is disposed in mechanical cooperation with at least one of the first jaw member and the second jaw member. Actuation of the actuation mechanism moves at least one of the first and second jaw members between an approximated position and an open position with respect to the other jaw member.

A surgical fastening instrument (100) comprising: a handle portion (160); an elongated portion (120) extending distally from the handle portion; an end effector including a cartridge assembly (130) and an anvil assembly (140), and being disposed adjacent a distal end of the elongated portion, a tissue contacting surface of the cartridge and anvil assembly is disposed substantially transverse to a longitudinal axis of the elongated portion, at least one of the cartridge assembly and the anvil assembly being movable with respect to the other from an open position to an approximated position for engaging body tissue therebetween, the cartridge assembly being configured to house a plurality of fasteners (300); and a knife (220) disposed in mechanical engagement with at least one jaw member, the knife including at least one of a longitudinally tapered tissue-contacting surface (222b) and a raised middle portion (222c).
摘要:
A compliant, e.g., foam, access device for positioning within a tissue tract for accessing an underlying body cavity includes a proximal portion, a distal portion, a body portion interconnecting the proximal and distal portions, and at least one port extending therethrough. The proximal portion includes a tissue facing surface and defines a first radial dimension. The distal portion extends longitudinally along an axial length and defines a second radial dimension that is substantially uniform along the axial length and smaller than the first radial dimension of the proximal portion. An adhesive is disposed on the tissue facing surface of the proximal portion for releasably securing and sealing the proximal portion to a tissue surface.
