摘要： A stitching device includes a handle assembly and an elongate shaft assembly. The handle assembly includes a main rod and a drive conversion assembly including a cam wheel, a pivot block, first and second links, and a pawl. The pawl is operatively coupled to the main rod, and is configured to engage the pivot block to cause rotation of the pivot block which, in turn, causes reciprocating displacement of the first and second links. The elongate shaft assembly includes first and second blade drive members coupled to the cam wheel. The tool assembly includes first and second jaws and first and second blades. The first and second blades are operatively coupled with the respective first and second blade drive members, wherein axial displacement of the main rod transitions the first and second jaws between open and closed positions and causes reciprocating axial displacement of the first and second blades.

摘要： A suture passer includes a handle, an elongated sleeve defining a distal end, an inner shaft slidably disposed within the elongated sleeve, and an end effector assembly disposed at a distal end of the inner shaft. The end effector assembly includes first and second arms, at least one which is movable relative to the other between a spaced-apart position and an approximated position for retaining a portion of a suture therebetween. The inner shaft and elongated sleeve are relatively movable between a first condition, wherein the first and second arms are disposed in the approximated position and the distal end of the elongated sleeve is exposed, a second condition, wherein the first and second arms are disposed in the approximated position and the distal end of the elongated sleeve is shielded, and a third condition, wherein the first and second arms are disposed in the spaced-apart position.

摘要： A surgical articulation assembly is disclosed, including a control assembly and an articulable portion. The articulable portion includes at least two segments capable of independent movement. The control assembly defines an axis and three user controls configured to be engaged by an operator. Disposed within the control assembly are three pairs of diametrically opposed driving members that effects translation of a connecting member upon engagement of the user controls. An end of the connecting member is attached to one of the first and second segments of the articulable portion. As the connecting member translates with the driving members, the three user controls allow an operator to exert forces at points along the articulable portion. Also disclosed is a method of effecting articulation of a surgical articulation assembly.

摘要： A surgical clip applier is provided including a clip pusher bar having a flexible tab and a camming plate configured to effectuate closure of the pair of jaws. The camming plate includes a lost motion portion and the flexible tab is configured to engage the lost motion portion during an initial movement of the clip pusher bar to cause the camming plate to move with the clip pusher bar. The flexible tab is configured to disengage from the lost motion portion during a subsequent movement of the clip pusher bar to allow the clip pusher bar to move relative to the camming plate.
