Surgical needle and method of manufacturing a surgical needle

1. Surgical micro-needle comprising:

an elongate needle body for a surgical micro-needle, and

a needle point formed on a distal end of the needle body, wherein:

the needle body is manufactured from an elongate cylindrical blank,

the needle body has at least one textured-profile lateral face, which comprises at least one textured-profile lateral-face region provided with an embossed textured profile in a stamping process,

the textured profile comprises a plurality of well-defined, reproducible indentations of a substantially pyramidal design,

the needle point is formed by electrochemical polishing of the stamped needle body such that the indentations are substantially retained, and

the at least one textured-profile lateral-face region extends as far as the needle point.

2. Needle according to claim 1 , wherein the at least one textured-profile lateral-face region forms at least half of the at least one textured-profile lateral face.

3. Needle according to claim 1 , wherein the needle body has two textured-profile lateral faces and the two textured-profile lateral faces face in opposite directions away from one another.

4. Needle according to claim 1 , wherein the needle body in cross section has a rectangular or square or substantially rectangular or square shape.

5. Needle according to claim 1 , wherein the needle body has four flat or substantially flat lateral faces and at least one of the lateral faces is a textured-profile lateral face.

6. Needle according to claim 1 , wherein the needle body has at least one non-profiled lateral face adjoining the at least one textured-profile lateral face.

7. Needle according to claim 6 , wherein the at least one non-profiled lateral face has a convex curvature in a direction away from the needle body.

8. Needle according to claim 6 , wherein two non-profiled or substantially non-profiled lateral faces are provided.

9. Needle according to claim 8 , wherein the two non-profiled or substantially non-profiled lateral faces face in opposite directions away from one another.

10. Needle according to claim 6 , wherein the needle body has two textured-profile lateral faces and wherein two non-profiled or substantially non-profiled lateral faces are provided, which connect the textured-profile lateral faces to one another.

11. Needle according to claim 1 , wherein the needle body is bent.

12. Needle according to claim 1 , wherein the at least one textured-profile lateral face defines an outer surface and wherein the plurality of indentations extend from the outer surface into the needle body.

13. Needle according to claim 12 , wherein a depth of the indentations relative to the outer surface of the at least one textured-profile lateral face decreases from a proximal end of the at least one textured-profile lateral-face region in the direction of the needle point.

14. Needle according to claim 1 , wherein the plurality of indentations are entirely or partially designed in the form of square pyramids.

15. Needle according to claim 1 , wherein the needle body is manufactured by injection moulding.

16. Needle according to claim 15 , wherein the needle body is manufactured by metal injection moulding (MIM), powder injection moulding (PIM) or by plastic injection moulding.

17. Needle according to claim 1 , wherein the needle is manufactured from a metal, a ceramic material or from plastics material.

18. Needle according to claim 1 , wherein the needle at a proximal end has at least one eye, blind hole or notch.

19. Needle according to claim 18 , wherein the eye is designed in the form of a through opening in the needle body that is circular, oval or elongate-hole-like in cross section.

20. Needle according to claim 1 , wherein the needle point and/or the entire needle body is entirely or partially coated with a silicone layer.
