Abstract

A device for fixing and tensioning at least one pulling thread for applying a neovagina comprises a base body on which at least one fixing element is arranged for fixing the at least one pulling thread with tensioning. The fixing element is able to turn about an axis of rotation in order to tension the at least one pulling thread, and a blocking device is provided for the fixing element, by means of which blocking device the fixing element can be blocked at least in a direction of rotation opposite to the direction of rotation for tensioning the at least one pulling thread.

Claims

1. A device for fixing and tensioning at least one pulling thread for applying a neovagina, comprising

a base body,

at least one fixing element arranged on said base body for fixing said at least one pulling thread and turnable about an axis of rotation for tensioning said at least one pulling thread by rotating said at least one fixing element in a first direction of rotation about said axis of rotation, and

a locking device for locking said at least one fixing element at least in a second direction of rotation opposite said first direction of rotation.

2. The device of claim 1, wherein said locking device has a latching mechanism for locking said fixing element in said second direction of rotation.

3. The device of claim 2, wherein said latching mechanism can be secured against undesired locking.

4. The device of claim 2, wherein said at least one fixing element has a wheel having a circumferential toothing which, in order to lock said at least one fixing element, interacts with a first catch element that can be brought into engagement with said toothing of said wheel.

5. The device of claim 4, wherein said first catch element can be locked when it is engaged with said toothing of said wheel.

6. The device of claim 5, wherein, in order to lock said first catch element, a second catch element is provided which can be shifted into a path of movement of said first catch element.

7. The device of claim 1, wherein said at least one fixing element has a slotted portion for receiving a portion of said at least one pulling thread, and a sleeve for clamping said at least one pulling thread on said at least one fixing element.

8. The device of claim 7, wherein said sleeve has a control wheel for turning said at least one fixing element.

9. The device of claim 1, wherein said at least one fixing element is assigned a spring whose first end is secured on said base body, and whose second end is configured for moveable connection to said at least one pulling thread and for deflecting said at least one pulling thread toward said at least one fixing element.

10. The device of claim 9, wherein a moveable guide roller is arranged at said second end of said spring.

11. The device of claim 1, wherein a feed point for said at least one pulling thread is present on said base body.

12. The device of claim 9, wherein a feed point for said at least one pulling thread is present on said base body, and said feed point is arranged in relation to said spring and to said at least one fixing element in such a way that said at least one pulling thread first runs from said feed point past said at least one fixing element to said second end of said spring and from there to said at least one fixing element.

13. The device of claim 12, wherein said feed point is arranged in relation to said spring and to said at least one fixing element in such a way that said at least one pulling thread is deflected at said second end through approximately 180°

toward said at least one fixing element.

14. The device of claim 11, wherein a moveable guide roller is present at said feed point.

15. The device of claim 1, wherein said at least one fixing element is designed for jointly fixing and tensioning said at least one pulling thread and at least one further pulling thread.

16. The device of claim 15, wherein a first feed point for said at least one pulling thread is present on said base body, and a second feed point for said at least one further pulling thread is provided on said base body, which second feed point is arranged, in relation to said at least one fixing element, opposite said first feed point.

17. The device of claim 9, wherein said at least one pulling thread is a first pulling thread, said spring is a first spring, and said at least one fixing element is designed for jointly fixing and tensioning said first pulling thread and at least one further pulling thread, and wherein a further spring for said at least one further pulling thread is arranged on said base body and, in relation to said at least one fixing element, is arranged opposite said first spring for said first pulling thread.

18. The device of claim 1, wherein said device can be autoclaved.

19. A device for fixing and tensioning at least one pulling thread for applying a neovagina, comprising

a base body,

at least one fixing element arranged on said base body for fixing said at least one pulling thread and turnable about an axis of rotation for tensioning said at least one pulling thread by rotating said at least one fixing element in a first direction of rotation about said axis of rotation, and

a locking device for locking said at least one fixing element at least in a second direction of rotation opposite said first direction of rotation, and a spring assigned to said at least one fixing element, whose first end is secured on said base body, and whose second end is configured for moveable connection to said at least one pulling thread and for deflecting said at least one pulling thread toward said at least one fixing element.

20. A device for fixing and tensioning at least one pulling thread for applying a neovagina, comprising

a base body, at least one fixing element arranged on said base body and turnable about an axis of rotation, said at least one fixing element being designed for jointly fixing said at least one pulling thread and at least one further pulling thread and tensioning said at least one pulling thread and said at least one further pulling thread by rotating said at least one fixing element in the direction of rotation about said axis of rotation.
