Abstract

The suture passer of the invention has a pair of opposed jaws. The lower jaw is formed by a hollow tube having its end turned upwardly to face the upper jaw. The hollow tube preferably extends from the lower jaw to a pair of handles. The tube can terminate anywhere along the length of the lower jaw. An upper jaw is hinged to the tube and provides a guide for a needle. The handles are used for the surgeon to grasp the device and to manipulate the jaws.

Claims

1. A suture passer, comprising:

a handle,

an upper jaw and lower jaw extending from said handle, said upper jaw and lower jaw movable relative to one another for grasping tissue,

a suture guide formed in said upper jaw, and

a suture returner formed in said lower jaw for allowing a surgeon to easily grasp a suture after it has passed through tissue, said suture returner comprising a passage in said lower jaw in communication with a passage in said handle further comprising a set screw in said handle for retaining a needle in said passage.

2. The suture passer of claim 1, wherein said suture guide is a forked end.

3. The suture passer of claim 1, wherein said suture guide is an aperture in said upper jaw.

4. The suture passer of claim 1, wherein said suture returner comprises an aperture in said lower jaw, said aperture sized to retain a needle attached to said suture.

5. A suture passer, comprising:

a handle,

an upper jaw and lower jaw extending from said handle, said upper jaw and lower jaw movable relative to one another for grasping tissue,

a suture guide formed in said upper jaw, and

a suture returner formed in said lower jaw for allowing a surgeon to easily grasp a suture after it has passed through tissue, wherein said suture returner comprises a passage below said handle, said passage terminating at said lower jaw.

6. The suture passer of claim 5, wherein said passage terminates in an enlarged head.

7. The suture passer of claim 6, where in said enlarged head has teeth.

8. The suture passer of claim 5, wherein said passage terminates in alignment with said suture guide.

9. A suture passer, comprising:

a handle,

an upper jaw and lower jaw extending from said handle, said upper jaw and lower jaw movable relative to one another for grasping tissue,

a suture guide formed in said upper jaw, and

a suture returner formed in said lower jaw for allowing a surgeon to easily grasp a suture after it has passed through tissue, further comprising teeth on said upper jaw.

10. A method for suturing tissue, comprising:

grasping tissue between an upper jaw and lower jaw of a suture passer,

passing the needle and suture through a suture guide in the upper jaw,

passing the needle and suture through the tissue, and

passing the needle and suture into a suture returner,

wherein passing the needle and suture into the suture returner comprises passing the needle and suture into a passage below a handle of the suture passer.

11. The method of claim 10, wherein passing the needle and suture through the suture guide comprises passing the needle and suture between forked ends of the upper jaw.

12. The method of claim 10, wherein passing the needle and suture through the suture guide comprises passing the needle and suture through an aperture in the upper jaw.

13. The method of claim 10, wherein passing the needle and suture into the suture returner comprises passing the needle and suture into a passage into a slot in the jaw sized to retain the needle.

14. The method of claim 10, wherein

the jaws open and the needle remains in the lower jaw as the suture passer is withdrawn.

15. A method for suturing tissue, comprising:

grasping tissue between an upper jaw and lower jaw of a suture passer,

passing the needle and suture through a suture guide in the upper jaw,

passing the needle and suture through the tissue, and

passing the needle and suture into a suture returner,

wherein passing the needle and suture into the suture returner comprises passing the needle and suture into a passage in the lower jaw and suture passer handle.

16. In combination, a suture passer and needle, comprising

a suture passer comprising a upper and lower jaw for grasping tissue, and a handle for manipulating said suture passer, said lower jaw having an aperture,

said needle comprising

a shaft,

a sharpened end at one end of the shaft,

a notch in diametrically opposed sides of said shaft spaced from said sharpened end, wherein said sharpened end enters said aperture in said lower jaw and said notch retains the needle in said aperture.

17. The needle of claim 16, further comprising

a pusher for pushing said needle through tissue.
