Abstract
Abstract A disposable applicator device for applying tubal occlusion clips, particularly clips utilized in mini-laparotomy sterilization surgery. The applicator includes a grasping lever for grasping the hook portion of the clip and a guiding arm for gripping, guiding and forcing the projection portion of the clip. The grasping lever and guiding lever are connected by swivel hinge and a separation restrictor such that the relative motion of the levers is restricted to a predetermined arc within a plane. The applicator is adapted to deliver a tubal occlusion clip into position, force the clip from an open mode to a closed mode about the desired tissue, and then slidably disengage from the clip, leaving the clip installed upon the tissue.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
225 words
A disposable applicator for surgical tubal occlusion clips comprising: a grasping lever for holding a hook portion of a Bleier tubal occlusion clip firmly in position, said grasping lever including in a substantially linearly attached manner, a loop handle, a grasping lever arm, a hinge area, a jaw arm, and a grasping jaw means, said grasping jaw means being formed in a shape to slidably receive the hook portion of a tubal occlusion clip and to restrict the motion of the hook portion received therein except along the slide axis; a guiding lever for guiding and forcing a projection portion of said tubal occlusion clip from a disengaged mode to an engaged mode with regard to the hook portion, the guiding lever including, in a substantially linearly attached manner, a loop handle, a guiding lever arm, and a guide arm containing a depression at the end thereof for lightly gripping the projection portion of the tubal occlusion clip and guiding the projection portion from a uniform open position to a closed position; hinge means connecting the grasping lever and the guiding lever and providing a mutual fulcrum for the levers; and restrictor means interposed between the grasping lever and the guiding lever for limiting both the maximum and minimum separation of the hook portion and said projection portion of the tubal occlusion clip held therebetween.
Claim 2
Dependent Claim
225 words
A disposable applicator for surgical tubal occlusion clips comprising: a grasping lever for holding a hook portion of a Bleier tubal occlusion clip firmly in position, said grasping lever including in a substantially linearly attached manner, a loop handle, a grasping lever arm, a hinge area, a jaw arm, and a grasping jaw means, said grasping jaw means being formed in a shape to slidably receive the hook portion of a tubal occlusion clip and to restrict the motion of the hook portion received therein except along the slide axis; a guiding lever for guiding and forcing a projection portion of said tubal occlusion clip from a disengaged mode to an engaged mode with regard to the hook portion, the guiding lever including, in a substantially linearly attached manner, a loop handle, a guiding lever arm, and a guide arm containing a depression at the end thereof for lightly gripping the projection portion of the tubal occlusion clip and guiding the projection portion from a uniform open position to a closed position; hinge means connecting the grasping lever and the guiding lever and providing a mutual fulcrum for the levers; and restrictor means interposed between the grasping lever and the guiding lever for limiting both the maximum and minimum separation of the hook portion and said projection portion of the tubal occlusion clip held therebetween.
Claim 3
Dependent Claim
20 words
