Abstract

A tensioning tool which holds the free ends of a tension band secured to a clip and clip screw and rotation of an adjusting knob causes tension to be applied to pull the band through the clip until the desired tension is achieved.

Claims

1. A tensioning tool for applying tension to a tension band held between a clip and a clip screw, the tension tool including a body having fixed positions for attaching ends of a tension band, a tension shaft having a proximal and a distal end and being constructed and arranged to hold a clip at its distal end and to be inserted through said body and attached at its proximal end to an adjusting mechanism which drives said tension shaft distally relative to said body, said tool further including a tension wrench for holding a screw and being constructed and arranged to pass through said tool proximally toward the distal end to thread a screw into a clip held at the distal end of said shaft.

2. The tensioning tool of claim 1 wherein said adjusting mechanism is a knob which is rotationally mounted to said body and said proximal end of said tension shaft is threaded into said knob such that rotation of said knob drives said shaft relative to said body.

3. The tensioning tool of claim 1 wherein said body fixed positions are slotted locking pins through which ends of a tension band may pass and be secured thereto.

4. The tensioning tool of claim 1 further including a side opening in said shaft adjacent said distal end such that a screw may be loaded onto said tension wrench.

5. The tensioning tool of claim 1 further including a tension spring within said body mechanism for displaying tension applied by the spring.
