Devices and methods for bending or cutting implants are disclosed herein. In some embodiments, an instrument can convert a rotational input force (e.g., supplied by a powered driver tool) into movement of a first rod holder with respect to a second rod holder. Such movement can form a bend in a rod or other implant held by the first and second rod holders. Various mechanisms for converting this movement are disclosed, such as a worm drive mechanism and a conical gear mechanism, as are various types of rod holders, including orbiting rollers, lid-type rod holders, fixed and pivoting half-pipe rod holders, and full-pipe rod holders. In some embodiments, the instrument can also be used for cutting, for example by rotating a cutting wheel with respect to a cutting plate to cut a rod or other implant inserted through openings formed in the cutting wheel and the cutting plate.

Devices and methods for bending or cutting implants

Devices and methods for bending or cutting implants are disclosed herein. In some embodiments, an instrument can include a rotatable drive shaft that urges first and second portions of a modular bending or cutting template toward one another to bend or cut an implant disposed between the template portions. A linkage assembly can be included to provide a mechanical advantage in urging the template portions toward one another. In some embodiments, an instrument can include a rotatable drive shaft that, depending on direction of rotation, pushes or pulls a first modular template portion with respect to a second modular template portion to bend an implant disposed between the template portions in one direction or another direction. In some embodiments, an instrument can include a worm drive that rotates a cutting wheel with respect to a cutting plate to cut an implant inserted through openings formed in the cutting wheel and the cutting plate.

Driver instruments are disclosed herein with various features for improving usability, easing the task of cleaning or sterilizing the instrument, reducing patient trauma associated with use of the instrument, and/or reducing the cost and assembly burden of the instrument. For example, a driver instrument can include a guide sleeve to protect patient tissue from damage caused by rotating components of the instrument or a bone anchor assembly coupled thereto, and to protect extension tabs of the bone anchor assembly from inadvertent separation. By way of further example, an instrument can include a preload assembly for maintaining engagement of a driver shaft of the instrument with a bone anchor assembly. As yet another example, an instrument can consist of a small number of components which are configured for simple, tool-free assembly and disassembly. An instrument can also be configured for use with bone anchor assemblies with and without extension tabs.
