Manual surgical ligation clip applier
First Claim
1. A ligation clip applier comprising:
- a pair of jaws;
a distal clevis tube to which the jaws are pivotally mounted via brackets defining a hole and a hinge pin extending through the hole;
a proximal clevis tube located behind the distal clevis tube, wherein the distal clevis tube and the proximal clevis tubes move axially with respect to each other;
a clip lock actuator fixed to one of the proximal and distal clevis tubes; and
a distal pushrod extending through the distal and proximal clevis tubes and forming a camming connection with the jaws configured to close and move the jaws toward a proximal direction toward the clip lock actuator when the distal pushrod is moved in the proximal direction.

Abstract
A ligation clip applier is provided. The clip applier includes: a pair of jaws; a distal clevis tube to which the jaws are pivotally mounted; a proximal clevis tube located behind the distal clevis tube, wherein the distal clevis tube and the proximal clevis tubes move axially with respect to each other; a clip lock actuator fixed to one of the proximal and distal clevis tubes; and a distal pushrod extending through the distal and proximal clevis tubes and forming a camming connection with the jaws configured to close and move the jaws toward a proximal direction toward the clip lock actuator when the distal pushrod is moved in the proximal direction. A method for applying a clip on a vessel is disclosed.

12. A ligation clip applier comprising:
-
a pair of jaws; a distal clevis tube to which the jaws are pivotally mounted; a proximal clevis tube located behind the distal clevis tube, wherein the distal clevis tube and the proximal clevis tubes move axially with respect to each other; a clip lock actuator fixed to one of the proximal and distal clevis tubes; and a distal pushrod extending through the distal and proximal clevis tubes and forming a camming connection with the jaws configured to close and move the jaws toward a proximal direction toward the clip lock actuator when the distal pushrod is moved in the proximal direction, wherein a wide diameter portion on the distal clevis tube and a wide diameter portion on the proximal clevis distal tube and the two wide diameter portions define a relief between the two wide diameter portions when the jaws are in an opened position and there is no relief between the two wide diameter portions when the jaws are fully closed.

13. A ligation clip applier comprising:
-
means for pinching; a distal clevis tube having eye brackets defining holes to which the means for pinching are pivotally mounted; a proximal clevis tube located behind the distal clevis tube, wherein the distal clevis tube and the proximal clevis tubes move axially with respect to each other; means for locking a clip fixed to one of the proximal and distal clevis tubes; and means for moving the means for pinching extending through the distal and proximal clevis tubes and forming a camming connection with the means for pinching configured to close and move the means for pinching toward a proximal direction toward the means for locking a clip when the means for moving the means for pinching is moved in the proximal direction.
