SYSTEM FOR TENSIONING A SURGICAL WIRE
First Claim
Patent Images
1. A device for tensioning a surgical wire, comprising:
- a frame including a distal end portion;
a drive assembly connected to the frame and defining an axis of travel; and
a carriage including opposing anchor sites configured to provide attachment of opposing end regions of a surgical wire extending to the anchor sites from the distal end portion of the frame, the carriage being connected to the drive assembly such that operation of the drive assembly drives the carriage away from the distal end portion of the frame, thereby providing an ability to apply tension to both end regions of the wire,wherein the carriage is pivotable about an axis transverse to the axis of travel such that the tension applied to the end regions of the wire is balanced dynamically.

10. A system for tensioning a surgical wire, comprising:
-
a tensioning device including (A) a frame including a distal end portion, (B) a drive assembly connected to the frame and defining an axis of travel, and (C) a carriage including opposing hitching brackets configured to provide attachment of opposing end regions of a surgical wire extending to the hitching brackets from the distal end portion of the frame, the carriage being connected to the drive assembly such that operation of the drive assembly drives the carriage away from the distal end portion of the frame, thereby providing an ability to apply tension to both end regions of the wire; and a surgical wire having opposing end regions each wrapped at least once around a respective hitching bracket. - View Dependent Claims (11, 12, 13, 14)

15. A method of bone fixation, comprising:
-
disposing a surgical wire around bone; attaching opposing end regions of the wire to a carriage that is pivotable transverse to an axis of travel; applying tension to both end regions of the wire by driving movement of the carriage away from the bone in a direction parallel to the axis of travel, the tension being dynamically balanced between the end regions by pivotal motion of the carriage; and securing the wire around the bone. - View Dependent Claims (16, 17, 18, 19, 20)
