Cerclage cable system and apparatus
A cerclage cable system is disclosed which includes a bone plate, one or more securing devices, and one or more cerclage cables. The bone plate includes a plurality of bone plate apertures thereupon, wherein the bone plate is configured to be affixed to a bone. The one or more securing devices include a body having a proximal end and a distal end, wherein at least one securing device aperture is disposed toward the proximal end, wherein the distal end of the securing device is configured to be inserted into and received by the plurality of bone plate apertures. The one or more cerclage cables include two terminal ends, wherein the one or more cerclage cables are wrapped around the bone, wherein one terminal end of the one or more cerclage cables is passed through at least one securing device aperture.
1. A cerclage cable tensioner comprising:
a body comprising a shaft having a proximal end and a distal end;
a modular tip disposed at the distal end of the shaft and removably affixed thereto;
a cam lock lever disposed adjacent to the modular tip, wherein the cam lock lever controls the locking and unlocking of the cam lock, wherein the cam lock acts on the cerclage cable;
a manually rotatable rotary actuator threadably disposed toward the proximal end of the shaft, wherein the rotary actuator is manually rotatable in opposite directions by a user, wherein one direction displaces a threaded cylinder to apply tension to the cerclage cable, and wherein the opposite direction retracts the threaded cylinder, thereby decreasing tension to the cerclage cable;
a squeeze actuator coupled to a linkage, wherein the linkage drives a central shaft forward to apply tension to the cerclage cable, such that both the manually rotatable rotary actuator and the squeeze actuator are configured to apply tension to the cerclage cable;
a tension release trigger, wherein tension release trigger releases a pawl that prevents the central shaft from moving in one direction and thereby releases tension from the squeeze actuator; and
a rear cam lock disposed at the proximal end of the shaft, wherein the rear cam lock secures the cerclage cable in the cerclage cable tensioner;
wherein a cerclage cable is threaded through the shaft from the modular tip at the distal end and through the proximal end of the shaft.
2. The cerclage cable tensioner of claim 1 , further comprising a tension gauge, wherein the tension gauge indicates the amount of tension applied to the cerclage cable.
3. The cerclage cable tensioner of claim 1 , further comprising a rear cam lock lever, wherein the rear cam lock lever controls the locking and unlocking of the rear cam lock.
4. The cerclage cable tensioner of claim 1 , further comprising a handle grip disposed toward the proximate end of the shaft, wherein both the squeeze actuator and tension release trigger extend therefrom and are coupled thereto.
5. The cerclage cable tensioner of claim 1 , wherein the modular tip, cam lock, and cam lock lever are detachable from the cerclage cable tensioner.
6. The cerclage cable tensioner of claim 5 , wherein the modular tip, cam lock, and cam lock lever remain attached to the cerclage cable after detaching from the cerclage cable tensioner.
7. The cerclage cable tensioner of claim 6 , wherein the modular tip, cam lock, and cam lock lever maintain a provisional tension on the cerclage cable.
8. The cerclage cable tensioner of claim 1 , wherein tension is maintained on the cerclage cable when the cam lock lever is closed, and wherein tension is released from the cerclage cable when the cam lock lever is opened.
9. A cerclage cable tensioner comprising:
a body comprising a shaft having a proximal end and a distal end;
a modular tip disposed at the distal end of the shaft and removably affixed thereto;
a cam lock lever disposed adjacent to the modular tip, wherein the cam lock lever controls the locking and unlocking of the cam lock, wherein the cam lock acts on the cerclage cable;
a manually rotatable rotary actuator threadably disposed toward the proximal end of the shaft, wherein the rotary actuator is manually rotatable in opposite directions by a user, wherein one direction displaces a threaded cylinder to apply tension to the cerclage cable, and wherein the opposite direction retracts the threaded cylinder, thereby decreasing tension to the cerclage cable;
a squeeze actuator coupled to a linkage, wherein the linkage drives a central shaft forward to apply tension to the cerclage cable, such that both the manually rotatable rotary actuator and the squeeze actuator are configured to apply tension to the cerclage cable;
a tension release trigger, wherein tension release trigger releases a pawl that prevents the central shaft from moving in one direction and thereby releases tension from the squeeze actuator;
a rear cam lock disposed at the proximal end of the shaft, wherein the rear cam lock secures the cerclage cable in the cerclage cable tensioner;
a rear cam lock lever, wherein the rear cam lock lever controls the locking and unlocking of the rear cam lock; and
a tension gauge, wherein the tension gauge indicates the amount of tension applied to the cerclage cable;
wherein the modular tip, cam lock, and cam lock lever are detachable from the cerclage cable tensioner, and wherein the cerclage cable is threaded through the shaft from the modular tip at the distal end and through the proximal end of the shaft.
10. The cerclage cable tensioner of claim 9 , further comprising a handle grip disposed toward the proximate end of the shaft, wherein both the squeeze actuator and tension release trigger extend therefrom and are coupled thereto.
11. The cerclage cable tensioner of claim 9 , wherein the modular tip, cam lock, and cam lock lever remain attached to the cerclage cable after detaching from the cerclage cable tensioner.
12. The cerclage cable tensioner of claim 11 , wherein the modular tip, cam lock, and cam lock lever maintain a provisional tension on the cerclage cable.
13. The cerclage cable tensioner of claim 9 , wherein tension is maintained on the cerclage cable when the cam lock lever is closed, and wherein tension is released from the cerclage cable when the cam lock lever is opened.
