Device for inserting at least one anchor piece into a hollow space of a living being
A device is used for inserting at least one anchor piece into a hollow space of a living being, in order to fix a wall of the hollow space temporarily to a wall of the body by means of the at least one anchor piece. It is proposed that the device has two shaft-like elements which are axially movable relative to one another and by which the at least one anchor piece is held captive at its axially spaced apart opposite ends, and moreover has an actuating mechanism via which the at least one element can be moved in such a way that the anchor piece held by it is released.
1. A device for inserting at least one anchor piece into a hollow space of a living being, in order to fix a wall of said hollow space temporarily to a wall of a body of said human being by means of said anchor piece, comprising
two shaft-like elements which are axially movable relative to one another along a longitudinal axis, wherein each of said two shaft-like elements has a jaw, and wherein one of said two shaft-like elements is designed as an outer tube having a distal end, and the other is designed as an axially displaceable inner shaft received in said outer tube, a distal end of said inner shaft is designed as a tip having a proximal end, said jaws being axially spaced apart along said longitudinal axis,
at least one anchor piece having two axially spaced apart opposite ends, said at least one anchor piece can be held captive between said axially spaced apart jaws of said two shaft-like elements at said axially spaced apart opposite ends, wherein one of said jaws is arranged on said distal end of said outer tube, and the other one of said jaws is arranged on said proximal end of said tip of said inner shaft, wherein each of said jaws has at least one pocket, a shape of said pocket corresponds to a shape of one of said opposite ends of said anchor piece held by said pocket, wherein the at least one pocket of each of said jaws contacts a respective opposite end of said anchor piece to prevent radial movement of said anchor piece, and
an actuating mechanism via which at least one of said two shaft-like elements can be moved in such a way that said anchor piece held between said two shaft-like elements can be released.
2. The device of claim 1 , wherein said two shaft-like elements are designed and arranged in such a way that a recess is formed between them in which said at least one anchor piece can be held.
3. The device of claim 2 , wherein said actuating mechanism has an actuating element for moving at least one of said two shaft-like elements, wherein, in a first position of said two shaft-like elements, said at least one anchor piece is held captive in said recess, and, in a second position of said two shaft-like elements, said at least one anchor piece can be fitted or released.
4. The device of claim 3 , wherein said actuating mechanism has a spring which acts on said at least one shaft-like element in such a way that said shaft-like elements are brought into said first position.
5. The device of claim 4 , wherein said actuating element, upon actuation counter to a force of said spring, moves said shaft-like elements in such a way that they are brought into the second position, and upon release of said actuating element, said shaft-like elements are brought back into said first position.
6. The device of claim 1 , wherein a head is arranged on a proximal end of said two shaft-like elements.
7. The device of claim 6 , wherein an actuating element designed as a push-button is arranged on said head.
8. The device of claim 7 , wherein said actuating element is movable in a direction of an axial movement of said two shaft-like elements.
9. The device of claim 1 , wherein said inner shaft is forced by means of a spring in a direction of a head arranged at a proximal end of said outer tube.
10. The device of claim 9 , wherein said inner shaft is operatively connected to said actuating mechanism in such a way that an actuation of an actuating element causes an axial displacement of said inner shaft along a longitudinal axis.
11. The device of claim 2 , wherein said recess is designed in such a way that two mutually opposite anchor pieces can be held in it.
12. The device of claim 11 , wherein each jaw has two mutually opposite pockets.
13. The device of claim 9 , wherein a mechanism for application of a trocar is arranged on said head.
14. The device of claim 1 , wherein an ejection mechanism is provided for ejecting said at least one anchor piece.
15. The device of claim 1 further including an anchor piece, wherein said anchor piece has a body designed in the shape of a strip.
16. The anchor piece of claim 15 , wherein said body is tubular shaped.
17. The anchor piece of claim 16 , wherein one of the shaft-like elements is designed as an outer tube, and wherein said tube section of said body is designed as a same geometric shape of said outer tube.
18. The anchor piece of claim 15 , wherein said anchor piece is rounded at both opposite ends.
19. The anchor piece of claim 15 , wherein said anchor piece is provided with at least one approximately central opening for engagement of a draw-thread.
20. The anchor piece of claim 15 , wherein said anchor piece is provided with at least one end opening for engagement of a retrieval thread.
