Abstract
Abstract A single surgical instrument to both pass a wire under a bone and twist the ends of the wire together is comprised of a hooked member mounted to a handle assembly. The hooked member has a notch to feed a wire as the hooked member is pulled about the bone. The handle assembly incorporates a crank comprised of two handles rotatably mounted to a grip to thereafter quickly and tightly twist the wires about the bone with the same instrument.

Total Claims: 17
Claim 1
Independent Claim
76 words
A surgical instrument for encircling and twisting a wire around a bone comprising: a hook for encircling a portion of the bone and pulling the wire closely therearound to thereby at least partially encircle said bone, the hook having a notch for securing one of said wire ends; and a crank for rapidly twisting the ends of said wire together to thereby tightly draw the wire about the bone, said crank being joined to said hook.
Claim 2
Dependent Claim

A surgical instrument for encircling and twisting a wire around a bone comprising: a hook for encircling a portion of the bone and pulling the wire closely therearound to thereby at least partially encircle said bone, the hook having a notch for securing one of said wire ends; and a crank for rapidly twisting the ends of said wire together to thereby tightly draw the wire about the bone, said crank being joined to said hook.
Claim 3
Dependent Claim
47 words
The surgical instrument of claim 1 wherein the hook is oriented with respect to said crank so that said hook may be moved around the circumference of a generally cylindrical bone by the twisting of a surgeon's wrist when said crank is held in a surgeon's hand.
Claim 4
Dependent Claim
37 words
The surgical instrument of claim 2 wherein the crank includes a grip, said hook being joined to said grip by a member which has at least a portion substantially perpendicular to a plane defined by said hook.
Claim 5
Dependent Claim
27 words
The surgical instrument of claim 3 wherein the crank includes a pair of offset handles, said handles being rotatably mounted to said grip at opposite ends thereof.
Claim 6
Dependent Claim
15 words
The surgical instrument of claim 4 wherein the hook is tapered towards its distal end.
Claim 7
Dependent Claim
13 words
The surgical instrument of claim 5 wherein said hook distal end is beveled.
Claim 8
Dependent Claim
25 words
The surgical instrument of claim 4 wherein said portion of the member is angled with respect to at least one of the pair of handles.
Claim 9
Dependent Claim
24 words
The surgical instrument of claim 7 wherein said member portion and said at least one handle are angled by an angle of approximately 15°.
Claim 10
Dependent Claim
63 words
A surgical instrument for fastening a bone with a wire by circumscribing the bone with the wire and twisting ends of the wire together, said instrument comprising: a hook configured to surround at least a portion of the bone for circumscribing the wire around the bone; and a crank for tightly twisting the wire ends together, the crank being joined with the hook.
Claim 11
Dependent Claim
63 words
A surgical instrument for fastening a bone with a wire by circumscribing the bone with the wire and twisting ends of the wire together, said instrument comprising: a hook configured to surround at least a portion of the bone for circumscribing the wire around the bone; and a crank for tightly twisting the wire ends together, the crank being joined with the hook.
Claim 12
Dependent Claim
19 words
