Abstract
Abstract There is provided a new and useful tendon approximator comprising a slide bar, a pair of needle arms mounted on the slide bar, at least one of which is slidably mounted for movement over a range of positions on the slide bar, each arm comprising an elongated member extending outwardly from the bar, having a transverse groove near the outer end thereof and a needle sleeve extending longitudinally therethrough, the groove bisecting the sleeve; and a clamp for securing each at least one arm at any desired position in the range.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
A tendon approximator comprising: a slide bar; a pair of needle arms mounted on said slide bar, at least one of which is slidably mounted for movement over a range of positions on said slide bar, each said arm comprising an elongated member extending outwardly from said bar, having a transverse groove near the outer end thereof and a needle sleeve extending longitudinally therethrough, said groove bisecting said sleeve; and means for securing each said at least one arm at any desired position in said range.
Claim 2
Dependent Claim
86 words
A tendon approximator comprising: a slide bar; a pair of needle arms mounted on said slide bar, at least one of which is slidably mounted for movement over a range of positions on said slide bar, each said arm comprising an elongated member extending outwardly from said bar, having a transverse groove near the outer end thereof and a needle sleeve extending longitudinally therethrough, said groove bisecting said sleeve; and means for securing each said at least one arm at any desired position in said range.
Claim 3
Dependent Claim
13 words
The approximator of claim 1 in which said needle arms are substantially parallel.
Claim 4
Dependent Claim
18 words
The approximator of claim 1 in which both said needle arms are slidably mounted on said slide bar.
Claim 5
Dependent Claim
29 words
The approximator of claim 3, in which said grooves are so located that they can be brought into proximity by sliding movement of said arms on said slide bar.
Claim 6
Dependent Claim
14 words
The approximator of claim 3 in which said grooves lie on a common axis.
Claim 7
Dependent Claim
19 words
The approximator of claim 3 in which said means for securing comprises for each said arm a screw clamp.
Claim 8
Dependent Claim
17 words
The approximator of claim 4 in which one said screw clamp is integral with each said arm.
Claim 9
Dependent Claim
17 words
The approximator of claim 3 in which the diameter of said transverse groove is approximately 4 millimeters.
Claim 10
Dependent Claim
17 words

Claim 11
Dependent Claim
34 words
The approximator of claim 1 in which the said arms are approximately 25 millimeters in length and the outer edges of said grooves are about 3 millimeters from the outer ends of said arms.
Claim 12
Dependent Claim
78 words
A tendon appproximator comprising: a slide bar; two parallel needle arms slidably mounted on said slide bar, each said arm comprising an elongated member extending outwardly from said bar, having a transverse groove near the outer end thereof and a needle sleeve extending therethrough, said grooves lying on a common axis and bisecting respective ones of said sleeves; and a pair of screw clamps for securing respective ones of said arms at preselected positions on said slide bar.
Claim 13
Dependent Claim
78 words
