  • Patent number: 7819299
    Abstract: A surgical instrument including a trigger which can be configured to close a jaw member upon a first actuation of the trigger and advance a staple driver and/or cutting member upon a subsequent, or second, actuation of the trigger. Such a surgical instrument can allow a surgeon to position the surgical instrument in a surgical site and close the jaw member with an initial actuation of the trigger without deploying any staples into, or incising, the tissue. As a result, the surgeon can manipulate the position of the surgical instrument and then actuate the trigger a second time to deploy staples into, and/or incise, the tissue. In at least one such embodiment, the first actuation of the trigger which closes the jaw member can also unlock a firing drive configured to advance the staple driver and cutting member during the second actuation of the trigger.

    Abstract: An electrosurgical stapling apparatus is provided which uses thermogenic energy as well as surgical fasteners or staples for strengthening tissue, providing hemostasis, tissue joining or welding. The thermogenic energy also strengthens tissue in proximity to a staple line and knife cut line and provides hemostasis along the staple and cut lines formed by the staples and a knife blade during surgical stapling. The use of thermogenic energy provides short-term hemostasis and sealing, and reduces or prevents staple line and cut line bleeding, while the stapling features provide short and long-term tissue strength and hemostasis. The stapling apparatus further substantially reduces or prevents knife cut line bleeding by energizing a knife blade for cauterizing tissue while it is being cut. In one embodiment, energy is applied to the anvil to energize the staples as they make contact with the anvil.

  • Patent number: 7407078
    Abstract: A surgical instrument for being endoscopically or laparoscopically inserted into a surgical site for simultaneous stapling and severing of tissue includes force adjusted spacing between an upper jaw (anvil) and a lower jaw (staple cartridge engaged to an elongate staple channel) so that the height of staple formation corresponds to the thickness of the tissue, yet does not exceed the height range that may be accommodated by the length of the staples. In particular, resilient structures are formed into an E-beam firing bar that includes a cutting surface (knife) that severs tissue between a top pin that engages the anvil and a middle pin and lower foot that engage the lower jaw. The resilience responds to the force exerted by clamped tissue to vary the spacing.

  • Publication number: 20080078808
    Abstract: A surgical staple including a crown comprised of a dissolvable, bioabsorbable, or biofragmentable material, a first deformable member, and a second member. In at least one embodiment, the crown connects the first member and the second member, however, after the crown has been dissolved, the first member is unconnected to the second member and, as a result, the first and second members can move relative to each other. Accordingly, the staple can be rigid during the early stages of healing and can be flexible during the latter stages of healing, for example. In various embodiments, the first and second members of the staple are also comprised of a dissolvable, bioabsorbable, or biofragmentable material. In these embodiments, the first and second members can be constructed so that the crown and first and second members dissolve at different rates and/or dissolve away at different times.
