Ceramic-tipped skull pins
View Patent ↗A skull pin including a removable tip is disclosed where the tip of the pin is manufactured from a ceramic material. Alternatively, the tip can be manufactured from other insulating, non-conducting materials. The tip may either be inserted into a bore in the center of the pin, or may be a cap placed over the pin.
1. A skull pin comprising:
a pin body; and
a pin tip formed from an insulating material, protruding from a proximal end of said pin body; wherein the protruding portion of said pin tip consists of a straight-sided portion and a tapered portion with a rounded tip, the curvature of which has a spherical radius in the range of 0.025 to 0.075 mm.
2. The skull pin of claim 1 , wherein said insulating material is a ceramic material.
3. The skull pin of claim 1 , wherein said insulating material is an electrical insulator.
4. The skull pin of claim 1 , wherein said pin body includes a bore for receiving said pin tip.
5. The skull pin of claim 1 , wherein said pin tip includes a bore for receiving said pin body.
6. The skull pin of claim 1 , wherein the tapered portion has an angle between 30° and 50°.
7. The pin of claim 1 wherein said straight-sided portion is cylindrical.
8. A kit comprising:
a halo; and
a skull pin, wherein said skull pin comprises
a pin body, and
an insert formed from an insulating material, protruding from a distal end of said pin body wherein the protruding portion of said insert consists of a straight-sided portion and a tapered portion with a rounded tip, the curvature of which has a spherical radius in the range of 0.025 to 0.075 mm.
9. The kit of claim 8 wherein said insulating material is a ceramic.
10. The kit of claim 8 wherein said straight-sided portion is cylindrical.
11. The kit of claim 8 wherein the tapered portion has an angle between 30° and 50°.
12. A kit comprising:
skull tongs; and
a skull pin, wherein said skull pin comprises
a pin body, and
an insert formed from an insulating material, protruding from a distal end of said pin body wherein the protruding portion of said insert consists of a straight-sided portion and a tapered portion with a rounded tip the curvature of which has a spherical radius in the range of 0.025 to 0.075 mm.
13. The kit of claim 12 wherein said insulating material is a ceramic.
14. The kit of claim 12 wherein said straight-sided portion is cylindrical.
15. The kit of claim 12 wherein the tapered portion has an angle between 30° and 50°.
