Abstract

To facilitate the production of a surgical vascular clip having two arms with clamping jaws, the arms being resiliently pressable against each other and meeting at an end section of the clip, and also having a tensioning section adjoining the end section in the direction towards the clamping jaws and being surrounded by a ring displaceable in the longitudinal direction of the tensioning section, it is proposed that the arms with the clamping jaws, the tensioning section and the end section be designed as a one-piece component.

Claims

1. A surgical vascular clip, comprising:

two arms with clamping jaws;

said arms being resiliently pressable against each other and meeting at an end section of said clip, and also having a tensioning section adjoining said end section in the direction towards said clamping jaws and being surrounded by a ring displaceable in the longitudinal direction of said tensioning section, wherein;

said end section has the shape of a circular cylinder which projects in the form of a step over said adjoining tensioning section; and

said tensioning section is closed off towards said clamping jaws by a projection.

2. A clip as defined in claim 1, wherein:

said projection has the shape of a shoulder surrounding said arms on the outside thereof.

3. A surgical vascular clip, comprising:

two arms with clamping jaws;

said arms being resiliently pressable against each other and meeting at an end section of said clip, and also having a tensioning section adjoining said end section in the direction towards said clamping jaws and being surrounded by a ring displaceable in the longitudinal direction of said tensioning section, wherein;

said arms with said clamping jaws, said tensioning section and said end section are designed as a one-piece component;

said tensioning section is closed off towards said clamping jaws by a projection;

said tensioning section widens conically from said end section to said clamping jaws; and

said arms are defined by a longitudinal slit extending in said clip as far as said end section, where said slit has essentially a constant width in the area of said clamping jaws, widens on entering said tensioning section and decreases in width again in the direction towards said end section.

4. A clip as defined in claim 3, wherein:

said tensioning section is closed off towards said end section by a projection.

5. A clip as defined in claim 4, wherein:

said projection has the shape of a shoulder surrounding said arms on the outside thereof.

6. A clip as defined in claim 3, wherein:

a cylindrical part adjoins said conically widening part of said tensioning section.

7. A clip as defined in claim 3, wherein:

said arms are corrugated in the longitudinal direction in the area of said tensioning section.

8. A clip as defined in claim 3, wherein:

in said tensioning section, said arms enclose between them a gap, the width of which increases from said end section toward said clamping jaws.

9. A clip as defined in claim 8, wherein:

said gap has at the clamping jaw end of said tensioning section end surfaces which are oriented towards the other arm.

10. A clip as defined in claim 8, wherein:

it consists of an elongate cylindrical part which is divided into two arms by a longitudinal slit extending as far as said end section.

11. A clip as defined in claim 8, wherein:

said arms are defined by a longitudinal slit extending in said clip as far as said end section, where said slit has essentially a constant width in the area of said clamping jaws, widens on entering said tensioning section and decreases in width again in the direction towards said end section.

12. A clip as defined in claim 3, wherein:

in said tensioning section, said arms enclose between them a gap, the width of which increases from said end section toward said clamping jaws.

13. A clip as defined in claim 12, wherein:

said gap has at the clamping jaw end of said tensioning section end surfaces which are oriented towards the other arm.

14. A clip as defined in claim 3, wherein:

areas of said arms are bent outwardly in arcuate configuration between said clamping jaws and said tensioning section.

15. A clip as defined in claim 14, wherein:

said areas of said arms bent outwardly in arcuate configuration are formed from a convex thickening of said cylindrical part by flattening on both sides and by convex widening of said longitudinal slit.

16. A clip as defined in claim 3, wherein:

said clip is formed as an elongate cylindrical part.

17. A surgical vascular clip, comprising:

two arms with clamping jaws;

said arms being resiliently pressable against each other and meeting at an end section of said clip, and also having a tensioning section adjoining said end section in the direction towards said clamping jaws and being surrounded by a ring displaceable in the longitudinal direction of said tensioning section, wherein;

said arms with said clamping jaws, said tensioning section and said end section are designed as a one-piece component;

said tensioning section is closed off towards said clamping jaws by a projection; and

said longitudinal slit has essentially a constant width in the area of said clamping jaws, widens on entering said tensioning section and decreases in width again in the direction towards said end section.

18. A surgical vascular clip, comprising:

two arms with clamping jaws;

said arms being resiliently pressable against each other and meeting at an end section of said clip, and also having a tensioning section adjoining said end section in the direction towards said clamping jaws and being surrounded by a ring displaceable in the longitudinal direction of said tensioning section, wherein;

said arms with said clamping jaws, said tensioning section and said end section are designed as a one-piece component;

said tensioning section widens conically from said end section to said clamping jaws; and

a cylindrical part adjoins said conically widening part of said tensioning section.

19. A surgical vascular clip, comprising:

two arms with clamping jaws;

said arms being resiliently pressable against each other and meeting at an end section of said clip, and also having a tensioning section adjoining said end section in the direction towards said clamping jaws and being surrounded by a ring displaceable in the longitudinal direction of said tensioning section, wherein;

said arms with said clamping jaws, said tensioning section and said end section are designed as a one-piece component;

said tensioning section is closed off towards said clamping jaws by a projection;

said tensioning section widens conically from said end section to said clamping jaws; and

a cylindrical part adjoins said conically widening part of said tensioning section.

20. A surgical vascular clip, comprising:

an elongate cylindrical part which is divided into two arms by a longitudinal slit extending as far as an end section of said clip;

said two arms having respective clamping jaws;

said arms being resiliently pressable against each other and meeting at the end section of said clip, and also having a tensioning section adjoining said end section in the direction towards said clamping jaws and being surrounded by a ring displaceable in the longitudinal direction of said tensioning section, wherein;

said arms with said clamping jaws, said tensioning section and said end section are designed as a one-piece component;

said tensioning section is closed off towards said clamping jaws by a projection;

said tensioning section widens conically from said end section to said clamping jaws; and

in said tensioning section, said arms enclose between them a gap, the width of which increases from said end section toward said clamping jaws.
