Abstract
Abstract Disclosured is a straightening and supporting device for the spinal column in the surgical treatment of scoliotic diseases, a device which is removed after the spinal column has healed. The device comprises a rod-shaped supporting member at least the length of the spinal column area to be treated and wires bearing on the ends of the supporting member and exerting a straightening and supporting effect on the vertebrae of the spinal column. Additionally, attachment members with loops, some of which being resilient, are arranged to the vertebrae, the wires being capable of sliding in the loops.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
A straightening and supporting device for the spinal column in the surgical treatment of scoliotic diseases, said device being removed after the spinal column has healed, said device comprising a rod-shaped supporting member, two resilient tractive wires disposed alongside said supporting member, said tractive wires being mounted on the end portions of said supporting member, a plurality of loops fitted on said wires, at least some of said loops on one of said wires being resilient attachment members adapted to be arranged on the vertebrae of said spinal column, said loops connecting said wires and said attachment members, said wires being capable of sliding in said loops, said wires exerting a straightening and supporting effect to said vertebrae.
Claim 2
Dependent Claim
118 words
A straightening and supporting device for the spinal column in the surgical treatment of scoliotic diseases, said device being removed after the spinal column has healed, said device comprising a rod-shaped supporting member, two resilient tractive wires disposed alongside said supporting member, said tractive wires being mounted on the end portions of said supporting member, a plurality of loops fitted on said wires, at least some of said loops on one of said wires being resilient attachment members adapted to be arranged on the vertebrae of said spinal column, said loops connecting said wires and said attachment members, said wires being capable of sliding in said loops, said wires exerting a straightening and supporting effect to said vertebrae.
Claim 3
Dependent Claim
34 words
A device according to claim 1 comprising adjusting means on said rod-shaped supporting member operable to adjust the longitudinal length of said rod-shaped supporting member to thereby regulate the tractive tension of said wires.
Claim 4
Dependent Claim
36 words
A device according to claim 1 comprising adjusting means on one of said tractive wires to adjust the longitudinal length of said one tractive wire to thereby regulate the tractive tension of said one tractive wire.
Claim 5
Dependent Claim
38 words
A device according to claim 1, wherein the ends of said wires are provided with attachment links with which said ends of said wires are attached to said rod-shaped supporting member after the straightening of the spinal column.
Claim 6
Dependent Claim
28 words
A device according to claim 1, wherein said rod-shaped supporting member is resilient in its longitudinal direction in order to produce a potential tractive tension in said wires.
Claim 7
Dependent Claim
20 words
A device according to claim 1, wherein said two tractive wires are disposed on opposite sides of said support member.
