Claims
- 1. An elastic surgical ring clip comprising:
- a body made of elastic material, said body having a generally spherical configuration exhibiting a pair of generally flattened and diametrically opposed faces, and
- means defining an anatomical tissue engaging lumen generally extending centrally through said elastic body with opposite ends of the lumen forming orifices centrally disposed in said opposed faces,
- said opposed faces having greatest cross-sectional dimensions in a plane perpendicular to a longitudinal axis of said lumen, substantially less than corresponding greatest cross-sectional dimensions of said spherical configuration of said body taken parallel to said plane,
- said body being made of an elastic material having sufficient elastic memory to return to its initial configuration after being stretched to enlarge said lumen so that tissue may be drawn into said lumen, whereby, upon return of said clip to its initial configuration with tissue located within said lumen, secure engagement of said clip about tissue is assured.
- 2. The surgical ring clip as claimed in claim 1 wherein said lumen is generally cylindrical in configuration.
- 3. The surgical ring clip as claimed in claim 1 wherein said lumen is generally elliptically configured in cross-section
- 4. The surgical ring clip as claimed in claim 1 wherein said lumen has a generally double channel configuration in cross-section with said channels being defined by inwardly extending nipples which can be separated to open the channels to each other thus to form a generally open figure eight lumen configuration in cross-section.
- 5. The surgical ring clip as claimed in claim 1 wherein said lumen is a generally narrow slit in cross-section.
- 6. The surgical ring clip as claimed in claim 1, further comprising in kit form a ring loader and a ring dilator for preparing a ring applicator device to apply one or more of said surgical ring clips, said ring loader comprising an elongate needle shaped receiver onto which one or more of said clips may be loaded by inserting the receiver through said clip lumen, a conically shaped ring clip expander having an apex and a base, said receiver extending from said apex and said base being configured to be temporarily mounted on the distal end of a ring applicator device, said ring dilator comprising a generally conically configured ring engaging portion and a base portion, said ring engaging portion being slit to define a plurality of ring engaging fingers for engaging an end of said elastic ring clip whereby one or more of said rings are advanced from said receiver, expanded by being pushed over said conical ring expander, and positioned on the distal end of a ring applicator by being pushed beyond said conical receiver base.
- 7. The surgical ring clip and ring loader, combination as claimed in claim 6 wherein said ring dilator base portion further comprises finger graspable means for facilitating a ring loading procedure.
- 8. The surgical ring clip and ring loader combination as claimed in claim 6 wherein said dilator ring engaging portion and base portion are of integral, one-piece construction and made of an elastic material whereby said fingers are spread apart as they are advanced over said conical expander.
- 9. A kit for preparing a ring applicator device to apply one or more elastic surgical rings onto anatomical tissue, comprising:
- a plurality of elastic surgical rings each having a substantially solid body made of elastic material, said body having a generally spherical configuration exhibiting a pair of generally flattened and diametrically opposed faces, and an anatomical tissue engaging lumen generally extending centrally through said elastic body with opposite ends of the lumen forming orifices centrally disposed in said opposed faces, said opposed faces having greatest cross-sectional dimensions in a plane perpendicular to a longitudinal axis of said lumen, substantially less than corresponding greatest cross-sectional dimensions of said spherical configuration of said body taken parallel to said plane, each of said bodies being made of an elastic material having suffificient elastic memory to return to an initial configuration after beomg stretched to enlarge said lumen so that anatomical tissue may be drawn into said lumen, whereby, upon return of said clip to its initial configuration with anatomical tissue located within said lumen, secure engagement of said clip about anatomical tissue is assured,
- a ring loader having an elongate needle shaped receiver onto which one or more of said elastic surgical rings are loaded with the receiver inserted through the lumen,
- a conically shaped elastic ring expander having an apex and a base, said receiver extending from said apex and said base being configured to be temporarily mounted on the distal end of a ring applicator device, and
- a ring dilator having a generally conically configured ring engaging portion being slit to define a plurality of ring engaging fingers for engaging an end of one of said one or more elastic rings loaded onto said receiver whereby one or more elastic rings may be advanced from the receiver, expanded by being pushed over said conical ring expander, and positioned on the distal e or a ring applicator be being pushed beyond said conical receiver base.
- 10. The kit as claimed in claim 9 wherein said ring dilator base portion further comprises finger graspable means for facilitating a ring loading procedure.
- 11. The kit as claimed in claim 9 wherein said ring engaging portion and said base portion are of integral, one-piece construction and made of a shape retaining elastic material whereby said fingers are spread apart as they are advanced over said conical expander and return to their original configuration after removal of said dilator from said loader.
- 12. The kit of claim 9, further comprising a plurality of said elastic surgical ring clips, some on said receiver and some separate from said receiver.
- 13. An elastic surgical ring clip for engaging anatomical tissue, comprising:
- a body made of elastic material; and
- means defining an anatomical tissue engaging lumen extending generally centrally through said elastic body, said body being made of an elastic mate having sufficient elastic memory to return to its initial configuration after being stretched to enlarge said lumen so that tissue may be drawn into said lumen, said lumen having generally an elliptical configuration in a cross-se taken in a plane perpendicular to a longitudinal axis of said lumen with major and minor axes of said elliptical configuration being perpendicular to said longitudinal axis with said major axis being greater in dimension than said minor axis.
- 14. The surgical ring clip of claim 13, wherein said lumen has a generally double channel configuration in cross-section with channels of said double channel configuration being defined by inwardly extending nipples which can be separated to open the channels to each other thus to form an open figure-eight lumen configuration in said cross-section.
- 15. The surgical ring clip of claim 13, wherein said lumen has a generally narrow slit configuration in said cross-section.
- 16. The surgical ring clip and ring loader combination as claimed in claim 6 wherein said ring engaging portion of said ring dilator has four ring engaging fingers.
- 17. The kit of claim 9 wherein said ring engaging portion of said ring dilator has four ring engaging fingers.
