  • Patent number: 10383627
    Abstract: A surgical staple-clip including a clip component and a securing member is used in a wide range of surgical procedures. The staple-clip may be introduced to a surgical site in an un-assembled condition through a small port or trocar. An applier for the staple-clip comprising a pair of opposed jaw-like channels is provided to position and apply the clip component and the securing member. The clip component is positioned around a target tissue and is compressed or clamped upon the tissue using only the force required for a specific surgical procedure such as occlusion, ligation or fixation. When the clip component is properly applied, the securing member is urged forward and over the clip component to secure the staple-clip. The clip component may include traction enhancement features such as surface interruptions, bumps, valleys and ridges.

  • Patent number: 10368862
    Abstract: A staple housing includes an array of staples each in a staple delivery position or “ready position” ready to be fired into target tissue. A staple driver is advanceable to drive the ready-position staples from the staple head into the tissue using staple pushers. During use, the staples in the ready positions are simultaneously fired into the target tissue using the staple pushers, forming an array of staples in the target tissue. After the array has been fired, one or more feed mechanisms within the staple housing advance a second group of staples from one or more staple storage locations into the ready positions in preparation for firing of the second group of staples.

  • Patent number: 9700324
    Abstract: A surgical clip applicator includes a base housing having a body portion, a movable trigger, a cannula, and a clip application mechanism extending within and through at least a portion of a length of the cannula. The clip application mechanism includes a movable first linkage and a jaw rotatable about a pivot mount. A first actuation of the trigger causes the first linkage to be moved in a linear direction with respect to the body portion and the cannula and the jaw to be rotated in a first direction about the pivot mount, for placing the clip in an open position on the patient's tissue. A second actuation of the trigger causes the jaw to be rotated in second direction about the pivot mount, the second direction being opposite to the first direction, placing the clip in a closed position on the patient's tissue.

  • Patent number: 9603599
    Abstract: A surgical instrument includes an anvil selectively coupleable to a stapling head assembly and a trigger operable to fire staples into tissue compressed between the anvil and the stapling head assembly. In some versions, a lockout member may engage a securing feature to prevent actuation of the anvil relative to the stapling head assembly. For instance, a tab may engage a slot on an actuator, a screen door lock may provide frictional resistance or engage teeth on the actuator, a door may actuate into engagement with one or more recesses, geared teeth may mesh with teeth on the actuator, the lockout member may include a ratcheting assembly to engage actuator, and/or a push button may actuate into a recess while disengaging the lockout member. Alternatively, in some versions, the trigger actuation assembly may be disengaged prior to firing. An anvil position indicator may restrict engagement of the trigger actuation assembly.
