Surgical instrument having a common trigger for actuating an end effector closing system and a staple firing system
ActiveUS7819299B2Quickly and conveniently selectSuture equipmentsStapling toolsSurgical operationSurgical site
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.

Triclosan and silver compound containing medical devices
The present invention relates to polymeric medical articles comprising combinations of triclosan and silver-containing compounds. It is based, at least in part, on the discovery that these agents act synergistically, thereby permitting the use of relatively low levels of both agents. While it had been previously found that triclosan can be particularly useful when used in conjunction with chlorhexidine, it has been further discovered that medical articles having suitable antimicrobial properties may be prepared, according to the present invention, which contain triclosan without chlorhexidine. Such medical articles offer the advantage of preventing or inhibiting infection while avoiding undesirable adverse reactions to chlorhexidine by individuals that may have sensitivity to chlorhexidine.
