DEVICES AND METHODS FOR BENDING OR CUTTING IMPLANTS

摘要

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.

主权项

1. An instrument for cutting an implant, comprising:
a housing having a drive shaft rotatably mounted therein, at least a portion of the drive shaft comprising a worm screw; a cutting wheel having at least one opening formed therein through which an implant can be received and a worm gear configured to engage the worm screw of the drive shaft such that rotation of the drive shaft is effective to rotate the cutting wheel; and a cutting plate having at least one opening formed therein through which an implant can be received; wherein rotation of the drive shaft is effective to rotate the cutting wheel relative to the cutting plate to cut an implant disposed through the at least one opening of the cutting wheel and the at least one opening of the cutting plate.
