  • Continuously engaged tangential driving tool
    Patent number: 5393036
    Abstract: Wrench for continuous driving engagement with a rotatively driven element such as a screw, bolt or nut, which is particularly suitable for use where the ends of the driven element are not accessible and in applications where space for manipulation of the tool is limited such as in spinal fusion surgery. The wrench has a peripheral driving element which can be engaged from the side with the driven element, and in some embodiments an articulating handle which enables the wrench to rotate the driven element through a substantial angle with only a few degrees of handle movement.
