Abstract

A surgical instrument holder, adapted to be received and retained by an operating room table clamping apparatus is disclosed. The inventive holder is particularly suited for adjustably mounting and stabilizing a laparoscope, endoscope or similar instrument which has an elongated shaft. The holder comprises a clamping assembly mounted at one end of the holder for holding the shaft of the instrument. The clamping assembly includes a pair of movable jaws adapted for being closed about the shaft of the instrument. Means carried by another end of the holder for cooperating with the operating room table clamping apparatus are provided.

Claims

1. A surgical instrument holder, adapted to removably retain one of a multiplicity of instruments for laparoscopic surgery;

said surgical instruments comprising elongated thin-wall tubular shafts, or various diameters;

said holder comprising a pair of moveable jaws for gripping said thin-wall tubular shaft, without deforming the walls thereof, the inner face of at least one of said jaws including an indentation for receiving and securely retaining said thin-walled tubular shafts of various diameters;

a bolt rotatably positioned through said moveable jaws;

a handle operatively secured to one end of said bolt for moving said jaws;

an attachment member mounted to said holder for removably securing said holder to an operating room table supporting apparatus;

whereby said surgical instrument may be stably positioned during laparoscopic surgery without support from humans.

2. The surgical instrument holder of claim 1, further including a spring for urging said jaws apart.

3. The surgical instrument holder of claim 2, further including guide means for opening and closing said jaws, said guide means comprising at least one rod which projects from one of said jaws, and a corresponding opening in said opposite jaw for slidably receiving said rod therein.

4. The surgical instrument holder of claim 1, wherein both jaws include an indentation in the confronting faces.

5. The surgical instrument holder of claim 4, wherein said indentations are identical notches.

6. The surgical instrument holder of claim 5, wherein each of said notches forms an obtuse angle at its apex.

7. The surgical instrument holder of claim 6, further including guide means for opening and closing said jaws, said guide means comprising at least one rod which projects from one of said jaws, and a corresponding opening in said opposite jaw for slidably receiving said rod therein.

8. The surgical instrument holder of claim 5, wherein each of said notches comprises a first inclined surface and a second inclined surface substantially smaller than said first inclined surface.

9. The surgical instrument holder of claim 8, wherein said means for cooperating with said operating room table clamping apparatus comprise an elongated arm secured to one of said jaws, substantially perpendicular to the longitudinal axis of said instrument being gripped by said holder.

10. The surgical instrument holder of claim 4, further including guide means for opening and closing said jaws, said guide means comprising at least one rod which projects from one of said jaws, and a corresponding opening in said opposite jaw for slidably receiving said rod therein.

11. The surgical instrument holder of claim 1, wherein said indentation is a notch.

12. The surgical instrument holder of claim 11, wherein said notch forms an approximately right angle at its apex.

13. The surgical instrument holder of claim 11, wherein said notch comprises a first inclined surface and a second inclined surface substantially smaller than said first inclined surface.

14. The surgical instrument holder of claim 1, wherein said spring is an elongated coil spring having an opening sufficiently large to receive said bolt;

said opening in each jaw through which said bolt passes being recessed to receive the opposite ends of said coil spring.

15. The surgical instrument holder of claim 14, wherein one of said jaw openings is internally threaded to engage corresponding threads on said bolt.

16. The surgical instrument holder of claim 14, wherein the inner face of one of said jaws defines an indentation for receiving and retaining the shaft of said instrument.

17. The surgical instrument holder of claim 16, wherein inner face of one of said jaws is roughened.

18. The surgical instrument holder of claim 16, wherein said indentation is a notch.

19. The surgical instrument holder of claim 16, wherein said indentation is curved.

20. The surgical instrument holder of claim 14, wherein both jaws include an indentation in the confronting faces.

21. The surgical instrument holder of claim 20, wherein both jaws include an indentation in their confronting faces which are identical.

22. The surgical instrument holder of claim 20, wherein each of said indentations is curved.

23. The surgical instrument holder of claim 14, wherein both jaws include roughened confronting faces.

24. The surgical instrument holder of claim 14, further including guide means for opening and closing said jaws, said guide means comprising at least one rod which projects from one of said jaws, and a corresponding opening in said opposite jaw for slidably receiving said rod therein.

25. The surgical instrument holder of claim 14, wherein said means for cooperating with said operating room table clamping apparatus comprise an elongated arm secured to one of said jaws, substantially perpendicular to the longitudinal axis of said instrument being gripped by said holder.

26. The surgical instrument holder of claim 1, further including guide means for opening and closing said jaws, said guide means comprising at least one rod which projects from one of said jaws, and a corresponding opening in said opposite jaw for slidably receiving said rod therein.

27. The surgical instrument holder of claim 26, wherein said means for cooperating with said operating room table clamping apparatus comprise an elongated arm secured to one of said jaws, substantially perpendicular to the longitudinal axis of said instrument being gripped by said holder.

28. The surgical instrument holder of claim 1, further including guide means for opening and closing said jaws, said guide means comprising at least one rod which projects from one of said jaws, and a corresponding opening in said opposite jaw for slidably receiving said rod therein.

29. The surgical instrument holder of claim 1, further including guide means for opening and closing said jaws, said guide means comprising at least one rod which projects from one of said jaws, and a corresponding opening in said opposite jaw for slidably receiving said rod therein.

30. The surgical instrument holder of claim 1, wherein said means for cooperating with said operating room table clamping apparatus comprise an elongated arm secured to one of said jaws, substantially perpendicular to the longitudinal axis of said instrument being gripped by said holder.

31. A holder for a disposable trocar adapted to removably retain the head of the disposable trocar which is generally made of plastic, said holder comprising:

a pair of moveable jaws for security gripping said trocar head, the inner face of at least one of said jaws including a plurality of serrations;

a bolt rotatably positioned through said movable jaws for moving said jaws;

means for preventing said jaws from closing beyond a predetermined distance to prevent said holder from being inadvertently applied to non-disposable laparoscopic instruments and thereby damaging said non-disposable instruments;

an attachment member, mounted to said holder, adapted to attach the holder to an operating room table supporting apparatus;

whereby said trocar may be stably positioned during laparoscopic surgery without support from humans.

32. The surgical instrument holder of claim 31 wherein said at least one rod has a first portion and a second portion opposite said first portion, said second portion having a diameter larger than the diameter of said opening in said opposite jaw, to prevent said jaws from closing beyond a predetermined distance.

33. The surgical instrument holder of claim 31 wherein said means for preventing said jaws from closing beyond a determined distance comprises guide means which includes at least one rod having a first portion and a second portion opposite said first portion, said second portion having a diameter larger than the diameter of said opening in said opposite jaws.

34. The surgical instrument holder of claim 31, wherein said bolt has a first portion that is threaded and a second portion that is unthreaded opposite said first portion to prevent said jaws from closing beyond a predetermined distance.
