CLAIMS

1. A neurological pin comprising a shaft with a sharp end and a blunt end wherein the sharp end is surrounded by an element defining an annular surface traversing the axis of the shaft.
2. A neurological pin according to Claim 1 wherein the annular surface defines a plane
substantially containing the point at the sharp end of the shaft.
3. A neurological pin according to Claim 1 wherein the annular surface defines a plane from which the sharp end of the shaft projects.
4. A neurological pin according to Claim 3 wherein the annular surface is substantially circular, and the sharp end projects beyond the plane of the annulus by a distance not exceeding the radius thereof.

5. A pin according to Claim 3 or Claim 4 wherein the annular surface is the boundary of a substantially planar surface perpendicular to the shaft and from which the sharp end of the shaft projects.
6. A neurological pin according to Claim 1 wherein the annular surface defines a plane traversing the axis of the shaft beyond the sharp end thereof.
7. A neurological pin according to any preceding Claim wherein the surrounding element is substantially rigid.
8. A neurological pin according to any preceding Claim wherein the surrounding element is fixed to the shaft.
9. A neurological pin according to Claim 8 wherein the surrounding element is formed integral with the shaft.
10. A neurological pin according to any of Claims

1 to 7 wherein the__surrounding element is mounted on the shaft for axial movement therealong.

11. A neurological pin according to any preceding Claim wherein the surrounding element is substantially conical, and convergent towards the blunt end of the shaft.
12. A neurological pin according to any preceding Claim including a roughened region formed on the shaft.

13. A neurological pin according to any preceding Claim wherein the shaft is formed with a lateral projection.
14. A neurological pin according to any preceding Claim wherein the blunt end of the shaft comprises a spherical body.
15. A neurological pin according to any preceding Claim wherein the tip at the sharp end of the shaft defines a substantially flat surface traversing the shaft axis.
16. A neurological pin according to Claim 15 wherein the shape of the flat surface is square.
17. A neurological pin according to any preceding Claim moulded in a plastics material.
