Rod reduction device and method of use

摘要

Provided is a novel rod reducing device including a screw jack mechanism that is moveably engaged with an elongated grasping fork assembly, the screw jack mechanism having an elongated threaded portion, the elongated threaded portion being connected at its most distal end to a rod contact member, which is positioned in sliding circumferential contact with each of the two opposing elongated grasping members and the most proximal end of the elongated threaded portion terminating in a controlling member, which can be activated in a measured and controlled manner. A method of using the device is also provided.

主权项

1. A rod reducing device, comprising:
a screw jack mechanism having an elongated threaded shaft terminating at a first proximal end with a controlling member and having at an opposite distal end a rod contact member; and an elongated grasping fork assembly having opposing first and second elongated grasping members, the first and second elongated grasping members pivotally coupled to a fork assembly body, the fork assembly body having a longitudinal axis, and each of said opposing first and second elongated grasping members having a screw grasping element at an opposite distal end, said elongated threaded shaft of said screw jack mechanism being threadably engaged along the longitudinal axis of said fork assembly body, wherein said rod contact member defines respective through passages configured for slidable passage of said opposing first and second elongated grasping members, slidable movement of the rod contact member along the first and second elongated grasping members exerts a compressive force upon said opposing first and second elongated grasping members, thereby causing pivotal movement of said opposing first and second elongated grasping members with respect to one another.
