Abstract
Abstract A skull fixation device. The device includes a clamp top portion, two clamp rods connected with the clamp top portion, and two bottom clamp legs connected with the two clamp rods. The two clamp rods are substantially coplanar such that the two clamp rods form an angle ranging between 30° and 150°. An imaginary surface formed by the coplanar two clamp rods is substantially perpendicular to the clamp top portion.

Claim 1
Independent Claim
138 words
A skull fixation device comprising: a clamp top portion; two clamp rods connected with said clamp top portion; and two bottom clamp legs each connected with a respective one of said two clamp rods; wherein said two clamp rods are substantially coplanar and form an angle ranging between 30° and 150°, and wherein an imaginary surface is formed by the two clamp rods is substantially perpendicular to said clamp top portion; wherein first ends of said two bottom clamp legs and first end of said clamp top portion are spaced at a first interval, second ends of said two bottom clamp legs and second end of said clamp top portion are spaced at a second interval; and wherein said first interval and said second interval are substantially equal and are on two opposite sides of said imaginary plane.
Claim 2
Dependent Claim
