Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 111 words
Orthopedic apparatus for external axial fixation comprising an elongate extendable central body, at the ends of which two pin-mounts are connected by means of ball-joints whose relation central lie on the 115 longitudinal axis of the central body, selectively operable means associated with each ball-jointfor locking a given orientation of the involved pinmounts, and selectively operable jack-mechanism operative nearthe ends of the central body, characte- 120 rized by the factthat central body is provided with at leastthree mutual lytelescoping parts with antirotation axial drive means and clamping means selectively operable between said parts, with two tubular eccentric pins rotatably located in parts which constitute support area fortwo pins of a jackmechanism.
Claim 2
Dependent Claim 111 words
Orthopedic apparatus for external axial fixation comprising an elongate extendable central body, at the ends of which two pin-mounts are connected by means of ball-joints whose relation central lie on the 115 longitudinal axis of the central body, selectively operable means associated with each ball-jointfor locking a given orientation of the involved pinmounts, and selectively operable jack-mechanism operative nearthe ends of the central body, characte- 120 rized by the factthat central body is provided with at leastthree mutual lytelescoping parts with antirotation axial drive means and clamping means selectively operable between said parts, with two tubular eccentric pins rotatably located in parts which constitute support area fortwo pins of a jackmechanism.
Claim 3
Dependent Claim 52 words
Apparatus as said in claim 1, characterized by the fact that a member is provided with an intermediate cylindrical sleeve, which is concentriGwith the 130 longitudinal axis of the body and radially interposed GB 2 168 255 A 3 with telescoping relation with inner and outer members, the latter having an opening.
Claim 4
Dependent Claim 103 words
Apparatus according to claim 1, characterized by the factthat the antirotation axial drive means and 5 clamping means between the central body members are comprised of two set-screws with an inner cylindrical flat end which may be screwed into the sleeve and in the outer member, and angularly offset both one in relation to the other with respectto the 10 plane containing the axes of the pins and of two grooves, with a flat end and lateral walls in coaction with the ends whose length is less inferiorto that of the chordal flats, on which they areformed, and of the inner memberand sleeve.
Claim 5
Dependent Claim 15 words
Apparatus according to claim 3, wherein the head of the set-screws is internally hexagon formed.
Claim 6
Dependent Claim 17 words
Apparatus according to claim 1, wherein the tubular pins atone of their ends are internally hexagon formed.
Claim 7
Dependent Claim 107 words
Apparatus according to claim 1, characterized by the fact that the jack-mecha nism comprises at least an outer, an intermediate and an inner cylindrical memberwhich are concentrically related along a displaceable axis, wherein each of intermediate and 25 outer members has an inner cylindrical bore and terminates at one of its ends with a radially inward threaded flange, having external threaded engagement with inner and intermediate members respectively and wherein each of said last mentioned 30 members terminates with a radially outward flange which is contained in the relative cylindrical bore of the two previously mentioned members, and wherein said threads have the same pitch and orientation.
Claim 8
Dependent Claim 91 words
Apparatus according to claim 6, wherein in the 35 outer member atthe opposite end to flange a radially outward pin is inserted and wherein the inner member atthe opposite side to flange is provided with a collar, beneath which, itterminates in an inward hexagonshaped end, rotatably connected with a boss by 40 means of a pin radially projecting outward the boss.
