Abstract

An implanting device is used for implanting a membrane in a biological tissue. The implanting device includes a sleeve, a membrane storage element, an injection element and a bubble generating element. The membrane storage element is fixed at the sleeve. The injection element is inserted in the sleeve and the membrane storage element, and includes a capturing end and connecting end. The capturing end is for capturing the membrane and has a hole. The bubble generating element is connected to the connecting end, and is for providing a gas that is then outputted via the hole. By the rotation of the injection element, the capturing end extends straight out of the membrane storage element or retracts straight into the membrane storage element.

First claim

What is claimed is:

1. An implanting device, adapted to place a membrane in a biologic tissue, the implanting device comprising:
a sleeve;
a membrane storage element, fixed at the sleeve;
an injection element, inserted in the sleeve and the injection element, comprising a capturing end and a connecting end, the capturing end for capturing the membrane and having a first hole; and
a bubble generating element, connected to the connecting end, for providing a gas that is outputted via the first hole;
wherein the capturing end, by rotation of the injection element, extends straight out of the membrane storage element or retracts straight into the membrane storage element;
wherein the injection element has a first outer diameter and a second outer diameter, and the first outer diameter is greater than the second outer diameter; the membrane storage element has a first inner diameter and a second inner diameter, and the first inner diameter is greater than the second inner diameter; the first outer diameter matches the first inner diameter, and the second outer diameter matches the second inner diameter.

2. The implanting device according to claim 1 , wherein the injection element comprises:
a rotation portion, rotatable relative to the rotation portion and connected in a straightly movable manner to the rotation portion; and
a tube body, rotatable relative to the sleeve and connected in a non-straightly movable manner to the sleeve.

3. The implanting device according to claim 2 , wherein the sleeve has an inner thread, and the rotation portion has an outer thread screw matching the inner thread.

4. The implanting device according to claim 2 , wherein the rotation portion has a first stop wall and a second stop wall facing each other, the injection element has a first flange, the first flange is configured on the tube body and is located between the first stop wall and the second stop wall, so as to confine relative straight movements of the tube body and the rotation portion.

5. The implanting device according to claim 2 , wherein the tube body has an injection channel, and the injection channel extends from the connecting end towards the capturing end communicates with the first hole.

6. The implanting device according to claim 5 , wherein the tube body comprises the connecting end and the first hole, the connecting end has a first opening, and the injection element communicates with an exterior through the first hole and the first opening.

7. The implanting device according to claim 1 , wherein the injection element has a first plane and a second plane facing each other, and the second outer diameter is a distance between the first plane and the second plane.

8. The implanting device according to claim 1 , wherein the injection element has a first outer end surface located outside the sleeve, the sleeve has a second outer end surface, the first outer end surface faces the second outer end surface, and the first outer end surface and the second outer end surface determine a first extremum position of the injection element relative to the sleeve.

9. The implanting device according to claim 1 , wherein the injection element has a third outer end surface located inside the sleeve, the sleeve has an inner end surface, the third outer end surface faces the inner end surface, and the third outer end surface and the inner surface determine a second extremum position of the injection element.

10. The implanting device according to claim 1 , wherein the capturing end comprise a first peripheral wall, and the first hole penetrates the first peripheral wall.

11. The implanting device according to claim 1 , wherein the capturing end has an end surface, and a distance between the first hole and the end surface is substantially equal to or greater than a radius of the membrane.

12. The implanting device according to claim 1 , wherein the first hole is a strip-shaped hole or a circular hole.

13. The implanting device according to claim 1 , wherein a quantity of the first hole is one.

14. The implanting device according to claim 1 , wherein the injection element has a second flange, the second flange protrudes from a second peripheral wall of the connecting end of the injection element, and the bubble generating element covers the second flange.

15. The implanting device according to claim 1 , wherein the membrane storage element has a storage channel, an outer diameter of the capturing end of the injection element is smaller than an inner diameter of the storage channel, and a space between the storage channel and the capturing end is for storing the membrane.

16. The implanting device according to claim 1 , wherein the injection element comprise a first tube and a second tube, the first tube is located in the sleeve and the membrane storage element and has the capturing end disposed on the first tube, and the second tube is connected to the first tube and located outside the membrane storage element and has the connecting end disposed on the second tube.

17. The implanting device according to claim 16 , wherein the first tube and the second tube are substantially perpendicularly connected.

18. The implanting device according to claim 1 , further comprising:
a non-return valve, configured at a first opening of the connecting end, having a second hole, wherein an inner diameter of the second hole is smaller than an inner diameter of the first opening;
wherein the non-return valve allows the gas to enter the injection channel.

19. The implanting device according to claim 1 , wherein the bubble generating element has a second opening and a third hole, the second opening is connected to the connecting end, and the bubble generating element communicates with an exterior through the third hole.
