Abstract
Abstract A surgical device for joining broken bone segments includes a rail member configurated to abut against one segment of the bone and has an aperture therein. A holder member has an aperture therein and is configurated to slide along the rail member and has a longitudinal slot through which fixing screws can pass and engage with the rail member for fixing the members against relative movement with respect to one another. An elongated connecting means passes through the apertures of the rail member and of the holder member. Each of the apertures define a pivot point in which the elongated member is pivotally mounted and forms an angle with the bone which is a function of the relative positions of the two members. One end of the elongated member is anchored to the holder member and another end is fixed to another segment of the bone, the elongated member being arranged to pull the last-mentioned segment towards said holder member while abutting against said rail member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
A surgical device, particularly for joining segments of an elongated broken bone such as a femur bone, comprising a first member connectable to at least one segment of the bone so as to extend longitudinally of the latter, said first member having a first aperture; an adjustable second member slidably mounted on said first member and having a second aperture, each of said apertures being tapered and defining on each of said members a pivot point; fixing means for fixing said first and second members in one of a plurality of relative positions; and elongated means arranged to pass through and pivot about the pivot points of each of the respective apertures and be securely fixed at one end portion to at least another of the bone segments while having another end portion arranged to abut against said second member for holding said other bone segment to said second member, said elongated member forming an angle with the elongation of said first member, and thereby of the bone which is a function of the relative position between said first and second members.
Claim 2
Dependent Claim
182 words
A surgical device, particularly for joining segments of an elongated broken bone such as a femur bone, comprising a first member connectable to at least one segment of the bone so as to extend longitudinally of the latter, said first member having a first aperture; an adjustable second member slidably mounted on said first member and having a second aperture, each of said apertures being tapered and defining on each of said members a pivot point; fixing means for fixing said first and second members in one of a plurality of relative positions; and elongated means arranged to pass through and pivot about the pivot points of each of the respective apertures and be securely fixed at one end portion to at least another of the bone segments while having another end portion arranged to abut against said second member for holding said other bone segment to said second member, said elongated member forming an angle with the elongation of said first member, and thereby of the bone which is a function of the relative position between said first and second members.
Claim 3
Dependent Claim
30 words
A surgical device as defined in claim 1, wherein said first member comprises a rigid rail configurated to extend along and abut against at least a part of the bone.
Claim 4
Dependent Claim
24 words
A surgical device as defined in claim 1, wherein said first member is connected to a segment of the bone by means of screws.
Claim 5
Dependent Claim
23 words
A surgical device as defined in claim 1, wherein each of said apertures taper in diameter in a direction away from the bone.
Claim 6
Dependent Claim
59 words
A surgical device as defined in claim 1, wherein said first and second members each have substantially straight portions arranged for sliding movement relative to one another, and wherein said second member has a further portion including an angle with the straight portion of said second member such that said further portion is substantially normal to said elongated member.
Claim 7
Dependent Claim
58 words
A surgical device as defined in claim 1, wherein said first and second members each have substantially straight portions arranged for slding movement relative to one another, and wherein said portion of said second member is provided with a longitudinal slot, said fixing means passing through said slot and engaging said portions of said first and second members.
Claim 8
Dependent Claim
14 words
A surgical device as defined in claim 6, wherein said fixing means comprises screws.
Claim 9
Dependent Claim
51 words
A surgical device as defined in claim 1, wherein said elongated means has portion positioned in said second aperture; and further comprising locking means on said second member in the region of said second aperture for engaging said portion and preventing movements of said elongated member relative to said second member.
Claim 10
Dependent Claim
16 words
A surgical device as defined in claim 1, wherein said locking means comprises a fixing screw.
