Bone screw fixing rod manipulation system

A rod manipulation system for manipulating a bone screw fixing rod, the bone screw fixing rod having two grooves generally parallel to each other, the rod manipulation system comprising:

• a fixing member having a first front end and a first distal end opposite to each other, wherein the first front end is provided with a rod-receiving recess for accommodating and fixing the bone screw fixing rod;
• a moving member having a second front end and a second distal end opposite to each other, wherein the second front end is provided with a rod-guiding notch for limiting and moving the bone screw fixing rod, and the second distal end is provided with a first thread;
• and
• a gripping part having a rotatable threaded member being disposed at a top end of the gripping part and a receiving cavity defined within the rotatable threaded member, wherein the receiving cavity is used for accommodating the first distal end of the fixing member and the second distal end of the moving member, and a side wall of the rotatable threaded member defining the receiving cavity is provided with a second thread configured to be engaged with the first thread, wherein the rotatable threaded member is connected with the second distal end,
• wherein the fixing member and the moving member are attached to each other,
• wherein two ends inside the rod-receiving recess of the fixing member are provided with first convex points, respectively, and the first convex points at the two ends inside the rod-receiving recess are parallel to each other and configured to respectively engage into the two grooves of the bone screw fixing rod to fix the bone screw fixing rod,
• wherein a second convex point is provided on a side wall of the rod-guiding notch of the moving member, and is configured to engage with one of the two grooves of the bone screw fixing rod to guide movement of the bone screw fixing rod.
