Abstract

A surgical stay-grip assembly includes a pair of jaws pivotally connected to one another and a jaw closing member, preferably a spring, for urging a first end of the jaws together. An elongated member, preferably elastic, is connected to one of the jaws. One jaw includes a receiver for securing the elongated member to the jaw. The other jaw preferably includes a receptacle adapted to secure an elongated member to this other jaw. When securing to the receptacle, the elongated member includes an enlarged end portion and the receptacle includes an opening adapted to retain the enlarged end portion within the receptacle. Preferably, the surgical stay-grip assembly includes a retractor hook assembly connected to the distal end of the elongated member.

Claims

1. A surgical stay-grip assembly comprising:

a first jaw having first and second ends;

a second jaw having first and second ends, said second jaw pivotally connected to said first jaw;

a jaw closing member for urging said first end of said jaws together; and

an elongated member having first and second ends, said first end of said elongated member connected to one of said jaws.

2. The surgical stay-grip assembly of claim 1, wherein said jaws are pivotally connected at cooperating concave and convex surfaces.

3. The surgical stay-grip assembly of claim 2, wherein said first jaw includes a convex articulating surface and said second jaw includes a concave articulating surface.

4. The surgical stay-grip assembly of claim 3, wherein said convex and concave articulating surfaces maintain alignment of said first jaw with said second jaw.

5. The surgical stay-grip assembly of claim 1, wherein said first end of said jaws abut in a closed position and are spaced apart in an open position.

6. The surgical stay-grip assembly of claim 1, wherein said jaw closing member is a spring.

7. The surgical stay-grip assembly of claim 6, wherein said spring is a torsion spring.

8. The surgical stay-grip assembly of claim 6, wherein said spring includes first and second arms, said first arm engaging said first jaw and said second arm engaging said second jaw.

9. The surgical stay-grip assembly of claim 6, wherein said spring maintains said jaws in pivotal relationship with each other.

10. The surgical stay-grip assembly of claim 1, wherein said first end of each said jaw includes a gripping surface.

11. The surgical stay-grip assembly of claim 10, wherein each said gripping surface includes serrated teeth.

12. The surgical stay-grip assembly of claim 1, wherein said first jaw includes a receiver for securing said elongated member to said first jaw.

13. The surgical stay-grip assembly of claim 12, wherein said receiver is adapted to releasably secure said elongated member to said first jaw.

14. The surgical stay-grip assembly of claim 12, wherein said receiver comprises an opening in said first jaw, said opening adapted to secure said elongated member to said first jaw.

15. The surgical stay-grip assembly of claim 14, wherein said receiver opening includes a tapered slot adapted to engagingly secure said elongated member to said first jaw.

16. The surgical stay-grip assembly of claim 1, wherein said second jaw includes a receptacle for securing said elongated member to said second jaw.

17. The surgical stay-grip assembly of claim 16, wherein said first end of said elongated member includes an enlarged end portion and said receptacle includes an opening adapted to retain said enlarged end portion within said receptacle.

18. The surgical stay-grip assembly of claim 1, further comprising a skirt extending between said second end of said jaws, said skirt including a skirt opening through which said elongated member extends, said skirt opening adapted to positionally maintain said elongated member.

19. The surgical stay-grip assembly of claim 1, further comprising a finger grip assembly adapted to attach to said second end of said jaws, said finger grip assembly providing a non-slip surface.

20. The surgical stay-grip assembly of claim 19, wherein said finger grip assembly includes a concave finger grip area.

21. The surgical stay-grip assembly of claim 12, wherein said second jaw includes a receptacle for securing said elongated member to said second jaw.

22. The surgical stay-grip assembly of claim 1, further comprising a retractor hook assembly connected to said second end of said elongated member.

23. The surgical stay-grip assembly of claim 22, wherein said elongated member is elastic.

24. A surgical stay-grip assembly comprising:

a pair of jaws, each jaw having first and second ends, said pair of jaws pivotally connected to one another;

a jaw closing member for urging said first end of said jaws together; and

an elongated, elastic member having first and second ends, said first end of said elongated member releasably connected to one of said jaws.

25. The surgical stay-grip assembly of claim 24, wherein said jaws pivot one upon the other at cooperating concave and convex articulating surfaces.

26. The surgical stay-grip assembly of claim 25, wherein said convex and concave articulating surfaces maintain alignment of one said jaw with the other said jaw.

27. The surgical stay-grip assembly of claim 24, wherein said jaw closing member is a torsion spring.

28. The surgical stay-grip assembly of claim 24, wherein said first end of each said jaw includes a gripping surface.

29. The surgical stay-grip assembly of claim 24, wherein one said jaw includes a receiver for securing said elongated, elastic member to said jaw.

30. The surgical stay-grip assembly of claim 29, wherein said receiver comprises an opening in the one said jaw, said opening adapted to secure said elongated, elastic member to the one said jaw.

31. The surgical stay-grip assembly of claim 30, wherein said receiver opening includes a tapered slot adapted to engagingly secure said elongated, elastic member.

32. The surgical stay-grip assembly of claim 29, wherein the other of said jaws includes a receptacle adapted to secure said elongated, elastic member to said jaw.

33. The surgical stay-grip assembly of claim 32, wherein said first end of said elongated, elastic member includes an enlarged end portion and said receptacle includes an opening adapted to retain said enlarged end portion within said receptacle.

34. The surgical stay-grip assembly of claim 24, further comprising a retractor hook assembly connected to said second end of said elongated, elastic member.

35. A method of assembly of a surgical retractor for retracting tissue during a surgical procedure, the surgical retractor including a clamping assembly and one of a plurality of hook assemblies, each hook assembly having an elongate, elastic member connected thereto, the method comprising the steps:

selecting the desired hook assembly for the surgical procedure; and

releasably securing the elongate, elastic member to the clamping assembly;

wherein the clamping assembly includes a pair of gripping jaws which are spring-biased in a closed position independent of the elongate elastic member.

36. The method of claim 35, wherein the step of releasably securing comprises a first receiver in the clamping assembly for receiving a portion of the elongate, elastic member.

37. The method of claim 35, further comprising the step of selecting between alternative means for securing the elongate, elastic member to the clamping assembly.

38. The method of claim 35, further comprising the step of attaching a skirt to the clamping assembly to maintain the elongate, elastic tail in a rearward direction from the clamping assembly.
