Abstract

A suture and needle combination is disclosed for use during surgical and non-surgical procedures comprising a suture needle 16 with a breakaway tip 20, insertable tip 24 or reusable tip 32. Suture 10 passes freely through hollow needle 16 after a user removes needle tip (20,24, or 32) during use. This suture needle combination reduces the amount of room needed within a surgical site, reduces the length of needle 16 needed to exit tissue (for example) while suturing, and decreased trauma to at risk anatomical structures during a surgical procedure or other use.

Claims

1. A needle and suture combination comprising:

a. a length of suture material, and

b. a hollow needle with a weakened segment that surrounds and encloses a portion of said suture material which is affixed to said needle a distance from said weaken segment,

whereby said weakened segment of said hollow needle provides a means to separate a portion of said needle with said suture attached.

2. A hollow needle and suture combination in accordance with claim 1 wherein:

said suture material is a monofilament, or

said suture material is multifilament, or

said suture material is braided,

wherein said suture varies in diameter and strength depending on application or procedure.

3. A suture material in accordance with claim 1 wherein:

said suture is a non-absorbable natural fiber material, or

said suture is a non-absorbable synthetic fiber material, or

said suture is a non-absorbable wire material, or

said suture is an absorbable natural material, or

said suture is an absorbable synthetic material.

4. A suture material in accordance with claim 1 wherein:

said suture is composed from a combination of said materials in claim 3.

5. A hollow needle and suture combination in accordance with claim 1 wherein:

said needle is straight, or

said needle is curved, and

said curved needle angle can be manufacture in any number of degrees,

wherein said straight needle and said curved needle length and diameter varies depending on application or procedure.

6. A hollow needle in accordance with claim 1 wherein:

said needle has a weakened segment on said needle outer surface, or

said needle has a weakened segment on said needle inner surface, or

said needle has weakened segments on both said inner surface and said outer surface, and

said needle has multiple said weakened segments along the length of said hollow needle,

which provides a means to vary the length of said portion of said needle when separated.

7. A hollow needle in accordance with claim 1 wherein:

said needle is composed of metal, or

said needle is composed of plastic, or

said needle is composed of a biological absorbable material.

8. A removable needle tip, a hollow needle shaft, and suture combination comprising:

a. a length of suture material, and

b. a separate needle tip having a tapered shaft, and

c. a hollow needle shaft that surrounds and encloses a portion of said suture material and said needle tip tapered shaft which has said suture affixed when assembled,

whereby said needle tip with said suture is removably mounted.

9. A removable needle tip in accordance with claim 8 wherein:

said needle tip provides a means to reattach said suture material, making said needle tip reusable.

10. A hollow needle shaft in accordance with claim 8 wherein:

Said needle shaft has an open end to accept said needle tip tapered shaft with said suture affixed, and

said needle shaft has a closed end,

wherein said needle shaft serves as a reservoir for said suture material.

11. A method of passing suture for use in surgical and non-surgical applications comprising the steps of:

a. providing a hollow needle having an open end and a sharp pointed end, said hollow needle has a weakened segment along said needle shaft, and

b. a length of suture material that enters said open end of hollow needle, travels within and passed said weakened segment where said suture material is then affixed to said suture needle,

whereby said hollow needle and said suture combination is passed through a media until said weakened segment exits said media, and said weakened segment with said suture material attached is separated from said hollow needle providing a means to pass said suture while also allowing withdrawal of remaining said hollow needle from said media leaving said suture material within.

12. A method of passing suture for use in surgical and non-surgical applications comprising the steps in claim 11,

wherein said suture and said needle combination has a needle tip that is removabaly mounted.
