Surgical clip applier with wide aperture surgical clips

A method of operating an end effector of a surgical clip applier, comprising:

• positioning the end effector adjacent a patient for operation, the end effector including:
• an elongate body;
• a clip track provided within the body and containing one or more surgical clips, wherein each surgical clip includes a crown and a pair of legs extending longitudinally from the crown and diverging from each other at an obtuse opening angle;
• a pre-forming region provided within the body and arranged to receive the one or more surgical clips from the clip track;
• and
• first and second jaw members positioned at a distal end of the body and arranged to receive the one or more surgical clips from the pre-forming region;
• advancing a distal-most surgical clip of the one or more surgical clips from the clip track to the pre-forming region;
• deforming the distal-most surgical clip in the pre-forming region from a first state, where the pair of legs of the distal-most surgical clip diverge at the obtuse opening angle, and a second state, where the obtuse opening angle is minimized;
• and
• advancing the distal-most surgical clip from the pre-forming region to the first and second jaw members in the second state.

A surgical clip applier, comprising:

• a drive housing;
• an elongate shaft that extends from the drive housing;
• and
• an end effector arranged at a distal end of the elongate shaft, the end effector including:
• an elongate body;
• a clip track provided within the body and containing one or more surgical clips, wherein each surgical clip includes a crown and a pair of legs extending longitudinally from the crown and diverging from each other at an obtuse opening angle;
• a pre-forming region provided within the body and arranged to receive and deform the one or more surgical clips from a first state, where the pair of legs diverge at the obtuse opening angle, and a second state, where the obtuse opening angle is minimized;
• and
• first and second jaw members positioned at a distal end of the body and arranged to receive the one or more surgical clips from the pre-forming region in the second state.
