Abstract

The invention relates to an instrument set for laparoscopic vaginal hysterectomy which comprises a uterine rotator comprising a rod with a uterine end for insertion into the uterus and a control end, and with at least one wing moveable in and out of the uterine end which in a folded-out position makes contact with the inner wall of the uterus and which is connected via coupling means to a control member located at the control end, wherein the rod is preferably provided with two wings, and more preferably the rod is provided with a hinge, and with optionally at least one artery forceps provided with a handle and mutually reciprocating jaws.

Claims

1. An instrument for laparoscopic vaginal hysterectomy, comprising:

a uterine rotator including a rod with a uterine end for insertion into uterus and a control end;

coupling means;

a control member; and

at least one wing, with the at least one wing movable from a folded-in position in the uterine end to a folded-out position in which the at least one wing makes contact with an inner wall of the uterus and with the at least one wing connected by the coupling means to the control member located at the control end, and wherein the uterine end of the rod is rotatably connected to the control end of the rod by a rotation means.

2. The instrument as claimed in claim 1, wherein the rod is provided with two wings.

3. The instrument as claimed in claim 2, wherein the wings are movable outwardly from the rod diametrically in relation to each other.

4. The instrument as claimed in claim 2, wherein the rod includes a rod tip and wherein each wing includes a first wing portion and a second wing portion connected for mutual rotation, with the first wing portion rotatably connected to a rod tip and with the second wing portion connected to the coupling means.

5. The instrument as claimed in claim 4, wherein the first wing portions are enclosed by the second wing portions in the folded-in position.

6. The instrument as claimed in claim 4, wherein adjoining second wing portions are separated from each other by an angle between 90°

and 180°

in the folded-out position.

7. The instrument as claims in claim 1, wherein the uterine end of the rod is connected to the control end of the rod by a plurality of hinges moveable transversely of each other.

18. The instrument set as claimed in claim 1, wherein each of the jaws pivots on a hinge element lying at a mutual distance.

8. An instrument for laparoscopic vaginal hysterectomy, comprising:

a uterine rotator including a rod with a uterine end for insertion into a uterus and a control end;

coupling means;

a control member; and

at least one wing, wherein the at least one wing is movable from a folded-in position in the uterine end to a folded-out position in which the at least one wing makes contact with an inner wall of the uterus, wherein the at least one wing is connected by the coupling means to the control member located at the control end and wherein the at least one wing is substantially enveloped within the rod in the folded-in position.

9. The instrument as claimed in claims 8, wherein the rod is provided with a recess for receiving the at least one wing in the folded-in position.

10. An instrument for laparoscopic vaginal hysterectomy, comprising:

a uterine rotator including a rod with a uterine end for insertion into a uterus and a control end;

coupling means;

a control member; and

at least one wing, wherein the at least one wing is movable from a folded-in position in the uterine end to a folded-out position in which the at least one wing makes contact with an inner wall of the uterus, wherein the at least one wing is connected by the coupling means to the control member located at the control end and wherein the uterine end of the rod has a substantially round shape in the folded-in position of the at least one wing.

11. An instrument for laparoscopic vaginal hysterectomy, comprising:

a uterine rotator including a rod with a uterine end for insertion into a uterus and a control end;

coupling means;

a control member; and

at least one wing, wherein the at least one wing is movable from a folded-in position in the uterine end to a folded-out position in which the at least one win makes contact with an inner wall of the uterus, wherein the at least one wing is connected by the coupling means to the control member located at the control end and wherein the coupling means include a coupling element in the rod.

12. An instrument for laparoscopic vaginal hysterectomy, comprising:

a uterine rotator including a rod with a uterine end for insertion into a uterus and a control end;

coupling means;

a control member; and

at least one wing, wherein the at least one wing is movable from a folded-in position in the uterine end to a folded-out position in which the at least one wing makes contact with an inner wall of the uterus, wherein the at least one wing is connected by the coupling means to the control member located at the control end and wherein the uterine end of the rod is connected by at least one hinge to the control end of the rod.

13. The instrument as claimed in claim 12, wherein the hinge is located at a distance from the uterine end such that a pivot point of the rod is located substantially adjacent the cervix of the uterus when the rod is inserted into the uterus.

14. The instrument as claimed in claim 12, wherein the rod is configured such that a pivoting movement takes place immediately forward of the at least one wing.

15. An instrument for laparoscopic vaginal hysterectomy, comprising:

a uterine rotator including a rod with a uterine end for insertion into a uterus and a control end;

coupling means;

a control member; and

at least one win, wherein the at least one wing is movable from a folded-in position in the uterine end to a folded-out position in which the at least one wing makes contact with an inner wall of the uterus, wherein the at least one win is connected by the coupling means to the control member located at the control end and wherein the uterine rotator is provided with a for nix presenter guided on the rod.

16. An instrument set for laparoscopic vaginal hysterectomy which comprises:

(a) a uterine rotator, including;

a rod with a uterine end for insertion into a uterus and a control end; and

at least one wing moveable from a folded-in position in the uterine end to a folded-out position in which the at least one wing makes contact with an inner wall of the uterus, wherein the at least one wing is connected by coupling means to a control member located at the control end, and (b) a pair of artery forceps provided with a handle and a plurality of mutually reciprocating jaws.

17. The instrument set as claimed in claim 16, wherein the artery forceps includes a curved shaft.
