Abstract
A system to precisely contour a surgical implant based on intraoperative information is disclosed.
Claims16
A system for intraoperatively contouring a spinal rod for placement onto the spine of a patient, comprising:
- a first contoured surrogate spinal rod,
- a second contoured surrogate spinal rod,
- a scanning assembly configured to scan the first contoured surrogate spinal rod and to output a first model based on the scan, and to scan the second contoured surrogate spinal rod and to output a second model based on the scan;
- a controller configured to receive the first model and to perform at least one analysis on the first model;
- and
- a contouring assembly configured to receive the first model from the controller and to contour the spinal rod based on the first model,
- wherein the contour of the first and the second contoured surrogate spinal rod is based at least in part on the intraoperative position of one or more pedicle screws implanted into the patient's spine,
- wherein the controller creates the second model based at least in part on the first model, the intraoperative position of the one or more pedicle screws and the position of the patient's spine;
- and
- wherein the controller is configured to compare the first and second model to determine whether they deviate from each other by more than a predetermined threshold.

A method for intraoperatively contouring a spinal rod using a system comprising:
- a first and second contoured surrogate spinal rod;
- a scanning assembly;
- a controller;
- and
- a contouring assembly;
- the method comprising:
- (A) using the scanning assembly, scanning the first contoured surrogate spinal rod to create a first model;
- (B) using the controller, performing at least one analysis on the first model created in (A);
- (B)(1) using the controller, creating a second model from the second contoured surrogate spinal rod and also based at least in part on the first model, the intraoperative position of one or more pedicle screws implanted into the patient's spine, and the position of the patient's spine;
- (B) (3) comparing the first and second model to confirm that they do not deviate from each other by more than a predetermined threshold;
- (C) using the controller, providing feedback relating to the results of the at least one analysis performed in (B);
- (D) providing the first model to the contouring assembly;
- and
- (E) using the contouring assembly, contouring the spinal rod based on the model created in (A).
