1. A driver for medical wires including:
a hollow drive shaft, rotatable about a rotation axis, the hollow drive shaft having an open distal end and a proximal end; a plurality of clamping jaws each having a longitudinal axis and each being movable along its longitudinal axis to penetrate under an angle into the hollow drive shaft close to its distal end, the plurality of clamping jaws defining an opening for guiding and holding a medical wire; a jaw guide mounted slidable parallel to the rotation axis and movably connected to the clamping jaws to move the clamping jaws into or out of the hollow drive shaft, the jaw guide pulling the clamping jaws back into a proximal direction or pushing the clamping jaws forward into a distal direction, therefore enlarging or decreasing the opening between the clamping jaws; and an actuator to shift the jaw guide parallel to the rotation axis and therefore modify the penetration depth of the clamping jaws, wherein the clamping jaws are located outside of the hollow drive shaft when the jaw guide pulls the clamping jaws out of the hollow drive shaft back into the proximal direction, and wherein the clamping jaws are located within the hollow drive shaft when the jaw guide pushes the clamping saws forward into the distal direction to clamp and hold the medical wire; and wherein the clamping jaws have a guiding cutout which interacts with a cam of the jaw guide. |
