  • Publication number: 20200015822
    Abstract: A surgical stapler includes a body portion and a tool assembly. The body portion includes a large diameter portion and a small diameter portion extending distally from the large diameter portion. The large diameter portion supports larger internal components of the device including a lockout assembly adapted to prevent refiring of the stapler to allow the diameter of the small diameter portion of the device to be minimized to facilitate passage of the small diameter portion of the stapler and the tool assembly through an 8 mm trocar.

The first jaw member includes a contact surface, a first projection, and a catch. The catch includes first and second fingers distal of the first projection. The second finger is biased toward the contact surface. The buttress material defines a longitudinal axis. The buttress material is releasably secured to the first jaw member. The buttress material defines first, second, and third slots formed therein. The first projection of the first jaw member is received in the first slot of the buttress material. The first finger of the catch is received in the second slot of the buttress material.

  • Patent number: 10258450
    Abstract: There are disclosed various embodiments of surgical tacks for use in surgical procedures. The tacks generally include a head and a barrel portion extending distally from the head. Preferably, the head and the barrel portion define a throughbore for receipt of a drive instrument. A thread on the head is provided to engage threads in the installation tool. A tissue thread is provided on the barrel portion to engage tissue. Distal and proximal surfaces of the tissue thread may be oriented at various angles relative to the barrel portion. There is also disclosed an insertion instrument to insert one or more tacks as well as a method of use. There is further disclosed a model device for use in explaining the operation of the instrument.

  • Publication number: 20190059878
    Abstract: A surgical stapling apparatus includes a cartridge assembly defining a tissue contacting surface; an anvil assembly defining a tissue contacting surface; and a surgical buttress releasably secured to at least one of the tissue contacting surface of the cartridge assembly and the tissue contacting surface of the anvil assembly by at least one anchor. A loading unit includes a surgical buttress releasably secured to an anvil assembly and/or a staple cartridge secured thereto by at least one anchor, and a drive assembly including a knife blade, wherein movement of the drive assembly from a proximal position to a distal position results in the knife blade cutting the at least one anchor and freeing each surgical buttress from the anvil assembly and/or cartridge assembly.

  • Publication number: 20170020524
    Abstract: A surgical stapler has a tool assembly including an anvil and a staple cartridge having a series of staples which are supported and configured to be rotatably ejected from the staple cartridge into the anvil to suture tissue. In embodiments, the surgical stapler includes a cartridge that supports a plurality of rotatable pushers. Each pusher supports a curved, substantially U-shaped staple having a single tissue penetrating distal leg portion and a proximal leg portion. The pusher is rotatable to drive the distal leg portion into an anvil to deform the staple into a substantially D-shaped configuration.
