Abstract

The present invention relates to a clip applier for clipping and dividing blood vessels, including: a handle; a first jaw unit; and a second jaw unit. The clip applier of the present invention can bring up two ligating clips at the same time with the first jaw unit and the second jaw unit, whereas the two clamping positions of the blood vessel can be clamped with the ligating clips simultaneously by the clip applier of the present invention in a single step, and thus the operating steps can be simplified, and the time involved with the surgical operation can be shortened.

Claims

1. A clip applier for clamping ligating clips, including:

a handle unit;

a first jaw unit including a first end having a first upper clipping portion and a first lower clipping portion, in which a first interval exists between the first upper clipping portion and the first lower clipping portion;

a second jaw unit including a second end having a second upper clipping portion and a second lower clipping portion, in which a second interval exists between the second upper clipping portion and the second lower clipping portion;

an advancing unit; and

a cutting unit, wherein the cutting unit connects to the advancing unit, the cutting unit is moved by the operation of the advancing unit, one end of the cutting unit locates in between the first jaw unit and the second jaw unit, and the advancing unit enables the cutting unit to move toward the ends of the first jaw unit and the second jaw unit;

wherein the first upper clipping portion corresponds to the second upper clipping portion to clamp a first ligating clip by operating the handle unit, the first lower clipping portion corresponds to the second lower clipping portion to clamp a second ligating clip by operating the handle unit, such that the first ligating clip and the second ligating clip are arranged for simultaneously clamping two clamping positions of a blood vessel.

2. The clip applier for clamping ligating clips as claimed in claim 1, wherein the handle unit has a first handle and a second handle, the first jaw unit and the first handle integrally form a first clip unit, the second jaw unit and the second handle integrally form a second clip unit, and the first clip unit and the second clip unit are pivotally connected.

3. The clip applier for clamping ligating clips as claimed in claim 2, further comprising a first flexible element located between the first clip unit and the second clip unit.

4. The clip applier for clamping ligating clips as claimed in claim 3, wherein the first flexible element is a spring or a leaf spring.

5. The clip applier for clamping ligating clips as claimed in claim 2, wherein the first clip unit or the second clip unit has a groove for receiving the advancing unit and enabling the advancing unit to move in the groove.

6. The clip applier for clamping ligating clips as claimed in claim 5, further comprising an elastic element received in the groove, and one end of the elastic element connects with the advancing unit.

7. The clip applier for clamping ligating clips as claimed in claim 6, wherein the other end of the elastic element connects to the edge of the groove.

8. The clip applier for clamping ligating clips as claimed in claim 2, further comprising a fixing part locating on the first clip unit or on the second clip unit, wherein the fixing part has a channel cavity, and the advancing unit passes through the channel cavity.

9. The clip applier for clamping ligating clips as claimed in claim 1, wherein the cutting unit comprises a first cutting component and a first connecting component, the first cutting component connects with the first connecting component, and the first connecting component connects with the advancing unit.

10. The clip applier for clamping ligating clips as claimed in claim 9, wherein the cutting unit further comprises a second cutting component and a second connecting component, the second cutting component connects with the second connecting component, and the first connecting component and the second connecting component are pivotally connected.

11. The clip applier for clamping ligating clips as claimed in claim 10, wherein the cutting unit further comprises a second flexible element locating between the first connecting component and the second connecting component.

12. The clip applier for clamping ligating clips as claimed in claim 11, wherein the second flexible element is a spring or a leaf spring.

13. The clip applier for clamping ligating clips as claimed in claim 1, wherein the cutting component is a blade or a billhook.

14. The clip applier for clamping ligating clips as claimed in claim 1, further comprising an elastic element wrapping around the advancing unit, wherein one end of the elastic element connects with the advancing unit.

15. The clip applier for clamping ligating clips as claimed in claim 14, wherein the other end of the elastic element connects with the fixing part.

16. The clip applier for clamping ligating clips as claimed in claim 1, wherein the first jaw unit further comprises a first elongation part, the second jaw unit further comprises a second elongation part, the first elongation part connects to the first end, and the second elongation part connects to the second end.

17. The clip applier for clamping ligating clips as claimed in claim 16, wherein the first elongation part connects to the first end with a first angle, and the second elongation part connects to the second end with a second angle.

18. The clip applier for clamping ligating clips as claimed in claim 17, wherein the first angle is ranged from 90 to 180 degrees.

19. The clip applier for clamping ligating clips as claimed in claim 17, wherein the second angle is ranged from 90 to 180 degrees.

20. The clip applier for clamping ligating clips as claimed in claim 17, wherein the first angle and the second angle are the same.
