Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
206 words
A coupler (10) for connection to a spinal rod (44), said coupler (10) comprising
a yoke means (12) including an opening (24) for accommodating the spinal rod
(44), the opening (24) of the yoke means (12) defining an axis, a body means (14)
including an opening (32) for accommodating the yoke means (12) in compressing
engagement with the spinal rod (44), the opening (32) of the body (14) defining
an axis characterised in that the body means (14) allows the yoke means (12) to
be accommodated such that the axis of the opening (24) of the yoke means (12)
may be non-parallel to the axis of the opening (32) of the body means (14) and
in that said yoke means (12) includes a generally U-shaped body having a pair of
integral legs (18), each of the legs including a lip (22) extending outwardly
therefrom generally transverse to the legs (18), the body means (14) being
generally C-shaped and including a pair of slots (38) in communication with the
opening (32) of said body means (14), each slot (38) accommodating a lip (22) of
the yoke means (12) in an interference fit to retain the yoke means (12) within the
opening (32) of the body means (14).
Claim 2
Dependent Claim
52 words
The coupler (10) of Claim 1 wherein the body means (14) further includes at least
one lip (36) extending over the opening of the body means (14) to constitute a
stop member to prevent the yoke means (12) from shifting along the axis of the
opening (32) of the body means (14).
Claim 3
Dependent Claim
27 words
The coupler (10) of Claim 1 wherein said body means (14) further includes a
secondary connection device for attaching the coupler body to a secondary
fixation point.
Claim 4
Dependent Claim
15 words
The coupler (10) of Claim 3 wherein the secondary connection device includes
hook body (50).
Claim 5
Dependent Claim
23 words
The coupler (10) of Claim 3 wherein the secondary connection device is a rod
portion (40) forming a part of a telescopic rod.
Claim 6
Dependent Claim
15 words
The coupler of Claim 3 wherein the secondary connection device is a threaded
screw shaft.
Claim 7
Dependent Claim
53 words
In combination, a spinal rod (44) and a coupling device (10) as claimed in claim
1, said spinal rod (44) having a longitudinal axis, said coupling device (10) being
connected to said spinal rod (44) such that the coupling device (10) may be non-perpendicular
to the longitudinal axis of the spinal rod (44).
