RATCHETING MECHANICAL DRIVER FOR CANNULATED SURGICAL SYSTEMS |
摘要 |
A device for rotatably driving a cannulated tool along a guide wire. In one aspect, the device includes a coupling assembly for receiving the tool and guide wire as well as a ratchet mechanism permitting selective rotation between the device and the tool. The device further includes an elongate gripping portion extending transversely to the coupling assembly to provide a levered mechanical advantage while positioning the gripping portion out of the path of the guide wire. In another aspect, the device includes a handle having a through bore shorter than a predetermined length of a connection assembly through bore so that only a short portion of the guide wire is covered by the device. A method of driving a cannulated tool along a guide wire is also provided that includes rotating a gripping portion of a handle assembly about the tool in an arcuate path spaced from the tool.
