Clip applicator, spreadable clips and method for applying the clips

Claim 2

A manual applicator for the application of spreadable surgical clips, comprising: a clip magazine having a clip discharge end and dimensioned and configured to releasably retain within the magazine a plurality of spreadable clips; a spreader mounted on said clip magazine by a rail member, at least part of the rail member being disposed between the spreader and the discharge end of the magazine to receive spreadable clips from the magazine and carry said clips on the rail member for guided movement of the clips thereon and onto the spreader, the spreader and the rail member each being dimensioned and configured to permit sliding movement thereover of the clips; and biasing means mounted on the applicator to urge the spreadable clips form the clip magazine towards the spreader; the spreader having an inlet section disposed adjacent to the discharge end of the magazine and a discharge tip which is wider in the clip-spreading direction than its inlet section, thereby providing the spreader with a wedge-shaped profile which diverges in the clip-spreading direction, whereby dislodgement of the spreadable clips from the clip magazine onto the spreader spreads the dislodged clip for ejection of it over the discharge tip of the spreader.

Claim 11

The applicator of claim 9 wherein the storage enclosure comprises a storage handle which is dimensioned and configured to be hand held during utilization of the applicator.

Claim 12

The applicator of claim 10 wherein at least a portion of the storage enclosure is sufficiently transparent to show the quantity of clips contained therein.

Claim 13

The applicator of claim 10 wherein the rail member extends at least part way through the storage handle and supports the spreader outside the storage handle.

Claim 14

The applicator of claim 12 wherein the rail member is cantilevered, having one end thereof supported by the storage handle and an opposite, free end which carries the spreader.

Claim 15

The applicator of claims 1 or 2 including biasing means carrier on the rail member to urge spreadable clips from the clip magazine towards the spreader and wherein the rail member has spreadable clips slidably mounted thereon.

Claim 16

A manual applicator for the application of spreadable surgical clips, comprising: a clip magazine having a clip discharge end and dimensioned and configured to releasably retain within the magazine a plurality of spreadable clips; a spreader mounted on said clip magazine by a rail member, at least part of the rail member being disposed between the spreader and the discharge end of the magazine to receive spreadable clips from the magazine and carry said clips on the rail member for guided movement of the clips thereon and onto the spreader, the spreader and the rail member each being dimensioned and configured to permit sliding movement thereover of the clips; the spreader having an inlet section disposed adjacent to the discharge end of the magazine and a discharge tip which is wider in the clip-spreading direction than its inlet section, thereby providing the spreader with a wedge-shaped profile which diverges in the clip-spreading direction, whereby dislodgement of the spreadable clips from the clip magazine onto the spreader spreads the dislodged clip for ejection of it over the discharge tip of the spreader; and a plurality of spreadable clips carried within the clip magazine, the spreadable clips respectively having a tubular body comprising a front face and a pair of opposed leg portion extending from a bight portion and terminating at their distal ends in respective bearing lips facing each other to define therebetween a clamping slit in the front face, an opening formed in the bight portion radially opposite the clamping slit and dimensioned and configured to accept and pass the support member and the spreader therethrough, whereby to spread apart the leg portions for the clip.

Claim 17

A manual applicator for the application of spreadable surgical clips, comprising: a clip magazine having a clip discharge end and dimensioned and configured to releasably retain within the magazine a plurality of spreadable clips; a spreader mounted on said clip magazine by a rail member, at least part of the rail member being disposed between the spreader and the discharge end of the magazine to receive spreadable clips from the magazine and carry said clips on the rail member for guided movement of the clips thereon and onto the spreader, the spreader and the rail member each being dimensioned and configured to permit sliding movement thereover of the clips; the spreader having an inlet section disposed adjacent to the discharge end of the magazine and a discharge tip which is wider in the clip-spreading direction than its inlet section, thereby providing the spreader with a wedge-shaped profile which diverges in the clip-spreading direction, whereby dislodgement of the spreadable clips from the clip magazine onto the spreader spreads the dislodged clip for ejection of it over the discharge tip of the spreader; and a plurality of spreadable clips carried within the clip magazine, the spreadable clips respectively having a tubular body comprising a front face and a pair of opposed leg portion extending from a bight portion and terminating at their distal ends in respective bearing lips facing each other to define therebetween a clamping slit in the front face, an opening formed in the bight portion radially opposite the clamping slit and dimensioned and configured to accept and pass the support member and the spreader therethrough, whereby to spread apart the leg portions for the clip.

Claim 18

The applicator of claim 15 wherein the rail member of the applicator is a cantilevered rail member and the clips are slidably mounted upon the rail member which passes through the rectangular opening and the clamping slit of respective clips.

Claim 19

The applicator of claim 15 wherein respective ones of the clips have a radially extending slot extending from one bearing lip to the rectangular opening to radially bifurcate one of the leg portions of the clip.

Claim 20

The applicator of claim 17 wherein the respective radially extending slots of the clips are aligned with the rail member and dimensioned and configured to accept the rail member slidably therein.

Claim 21

The applicator of claim 18 wherein the clips are slidably mounted upon the rail member, which passes through the radially extending slots of the clips.

Claim 22

The applicator of claims 1 or 2 wherein the rail member extends at least part way through the clip magazine, and including a plurality of spreadable clips carried on the rail member within the clip magazine.

Claim 23

A manual applicator for the application of spreadable surgical clips, comprising: a clip magazine comprising a storage handle having mounted therein a rail member which is dimensioned and configured to slidably receive a plurality of spreadable surgical clips thereon, and upon which is supported a spreader having an inlet section facing the storage handle and a discharge tip at its end opposite its inlet section, the spreader being wider in the clip-spreading direction at its discharge tip than at its inlet section so as to have a wedge-shaped profile in the clip-spreading direction; whereby dislodgement of the spreadable surgical clips from the rail member onto the spreader spreads the dislodged clip on the spreader, from which the spread clip may be ejected over the discharge tip thereof, the applicator including biasing means mounted thereon to urge the spreadable clips from the rail member towards the spreader.

Claim 24

A manual applicator for the application of spreadable surgical clips, comprising: a clip magazine comprising a storage handle having mounted therein a rail member which is dimensioned and configured to slidably receive a plurality of spreadable surgical clips thereon, and upon which is supported a spreader having an inlet section facing the storage handle and a discharge tip at its end opposite its inlet section, the spreader being wider in the clip-spreading direction at its discharge tip than at its inlet section so as to have a wedge-shaped profile in the clip-spreading direction; whereby dislodgement of the spreadable surgical clips from the rail member onto the spreader spreads the dislodged clip on the spreader, from which the spread clip may be ejected over the discharge tip thereof, the applicator including biasing means mounted thereon to urge the spreadable clips from the rail member towards the spreader.

Claim 25

The applicator of claim 21 including a plurality of spreadable clips carried within the clip magazine thereof.
