Surgical clip applicator
First Claim
1. A surgical clip applicator comprising:
- a base housing including a body portion;
a trigger movable with respect to the body portion;
a cannula having a first end positioned within the body portion and an opposing second end, a portion of the second end being configured as a first jaw to engage a clip to be applied to a patient'"'"'s tissue, anda clip application mechanism extending within and through at least a portion of a length of the cannula, the clip application mechanism including;
a first linkage movable with respect to the body portion and the cannula,a second linkage movable with respect to the body portion and the cannula, the second linkage having a first end rotatable about a first pivot mount and an opposing second end and a second jaw for engaging the clip provided at the second end, the second jaw being rotatable about a second pivot mount, anda lower frame having a first end and an opposing second end and a longitudinal axis extending therebetween, the second linkage being pivotably coupled to the lower frame about the first pivot mount and being formed radially inwardly of the lower frame with respect to the longitudinal axis of the lower frame,wherein a first actuation of the trigger causes the second linkage to be rotated in a first direction about the first pivot mount, and the second jaw to be rotated in a second direction about the second pivot mount, the second direction being opposite to the first direction, to place the clip in an open position, andwherein a second actuation of the trigger causes the second linkage to be rotated in the second direction about the first pivot mount and the second jaw to be rotated in the first direction about the second pivot mount to place the clip in a closed position on the patient'"'"'s tissue.

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.
