Pelvic Cable Solution
A device for treating bone fractures, comprises an actuating mechanism removably coupleable to a clamping mechanism including a clamp defining a cable receiving channel extending therethrough and a compression member coupled to the clamp for movement relative thereto, movement of the compression member relative to the clamp in a first direction moving the clamping mechanism into a clamping configuration in which at least a portion of the clamp is compressed into the channel to fix a cable received therein relative to the clamping mechanism. The actuating mechanism includes a first member and a second member removably engagable with a clamping mechanism so that, when engaged, relative movement between the first and second members causes relative movement between the clamp and the compression member to move the clamping member between the clamping configuration and a release configuration, the actuating mechanism further including a tensioning mechanism.
1. A device for treating bone fractures, comprising:
an actuating mechanism removably coupleable to a clamping mechanism including a clamp and a compression member coupled to the clamp for movement relative thereto, the clamp defining a cable receiving channel extending therethrough and including a compressible portion at a proximal end thereof, the compressible portion of the clamp including a longitudinal slot extending along a portion of a length thereof to define separated portions, wherein movement of the compression member relative to the clamp in a first direction moves the clamping mechanism into a clamping configuration in which the separated portions of the compressible portion are moved radially into the channel to fix a cable received therein relative to the clamping mechanism, the actuating mechanism including:
a first member removably engagable with the clamping mechanism so that, when engaged, the first member prevents relative movement between the clamp and the first member, the first member including a projection engagable with the longitudinal slot of the compressible portion of the clamp such that, when engaged, the clamp prevents relative rotation between the clamp and the first member;
a second member removably engagable with the clamping mechanism and movably coupled to the first member so that, when engaged, the second member prevents relative movement between the compression member and the second member, relative movement between the first and second members causing relative movement between the clamp and the compression member to move the clamping member between the clamping configuration and a release configuration in which the cable is permitted to move through the clamping mechanism; and
a tensioning mechanism for drawing the cable through the clamping mechanism and applying a desired degree of tension thereto.
2. The device of claim 1 , wherein the compression member is rotatable relative to the clamp.
3. The device of claim 2 , wherein the compression member is moveable along a longitudinal axis when rotated relative to the clamp.
4. The device of claim 2 , wherein the clamp and compression member have corresponding threading such that rotational movement of the compression member relative to the clamp causes the compression member to move longitudinally relative to the clamp.
5. The device of claim 1 , wherein the first member is housed substantially within the second member.
6. The device of claim 1 , further comprising a handle coupleable to a proximal end of the second member.
7. The device of claim 6 , wherein the second member is rotatable via the handle.
8. The device of claim 1 , wherein a proximal end of the clamp is tapered to engage a corresponding surface of the compression member.
9. A method, comprising:
sliding a clamping mechanism over a cable, the clamping mechanism including a clamp and a compression member coupled to the clamp for movement relative thereto, the clamp defining a cable receiving channel extending therethrough and including a compressible portion at a proximal end thereof, the compressible portion of the clamp including a longitudinal slot extending along a portion of a length thereof to define separated portions, relative movement of the compression member relative to the clamp in a first direction moving the clamping mechanism into a clamping configuration in which separated portions of the compressible portion are moved radially into the channel to fix the cable received therein relative to the clamping mechanism;
removably coupling an actuating mechanism to the clamping mechanism, the actuating mechanism including a first member, a second member and a tensioning mechanism, the first member including a projection removably engaging the longitudinal slot of the compressible portion of the clamp to prevent relative movement between the clamp and the first member, the second member removably engaging the compression member to prevent relative movement between the compression member and the second member;
drawing the cable through the clamping mechanism and applying a desired degree of tension thereto via the tensioning mechanism; and
moving the second member relative to the first member to move the compression member into the clamping configuration.
10. The method of claim 9 , wherein moving the second member relative to the first member comprises rotating the first and second member relative to one another to rotate the compression member relative to the clamp.
11. The method of claim 10 , wherein rotation of the compression member relative to the clamp moves the compression member along a longitudinal axis of the clamp.
12. The method of claim 11 , wherein the clamp and compression member have corresponding threading such that rotational movement of the compression member relative to the clamp moves compression member longitudinally relative to the clamp.
13. The method of claim 10 , wherein the first member is housed substantially within the second member.
14. The method of claim 10 , wherein the actuating mechanism includes a handle coupleable to a proximal end of the second member, further comprising rotating the second member relative to the first member by rotating the handle relative to the second member.
15. The method of claim 10 , wherein a proximal end of the clamp is tapered to engage a corresponding surface of the compression member.
