Abstract

A system for planning a spine surgery, comprising a haptic interface capable of providing force feedback to the user and a computer adapted to simulate a surgical procedure by responding to inputs from the haptic interface and outputting haptic feedback to the haptic interface is provided.

The system further comprising a rapid prototyping unit including a unit that is adapted to create models of the anatomical region where the surgical procedure will be performed in its current unoperated condition and in the predicted postoperative condition. Further the rapid prototyping unit is adapted to create a three dimensional guide to be used in the surgical procedure as well as suggest revisions to the surgical procedure. The system further comprises a computer that simulates loading of the spine and planned implanted hardware using finite element software.

Claims

1. A system for planning a spine surgery, comprising:

a haptic interface capable of providing force feedback to the user;

a computer adapted to simulate a surgical procedure by responding to inputs from the haptic interface and outputting haptic feedback to the haptic interface.

2. The system of claim 1 further comprising a rapid prototyping unit.

3. The system of claim 2 wherein the rapid prototyping unit is adapted to create models of the anatomical region where the surgical procedure will be performed in the current unoperated condition and the predicted postoperative condition after the planned surgery.

4. The system of claim 2 wherein the rapid prototyping unit is adapted to create a guide to be used in the surgical procedure for accurately positioning surgical implants such as screws or artificial discs.

5. The system of claim 1 wherein the computer is adapted to suggest revisions to the surgical procedure.

6. The system of claim 1 wherein the computer simulates loading of the spine and planned implanted hardware using finite element software.

7. A system for planning spine surgery, comprising:

a haptic interface capable of providing force feedback to the user;

a computer adapted to simulate a surgical procedure by responding to inputs from the haptic interface and outputting haptic feedback to the haptic interface;

a rapid prototyping unit adapted to create a model of the anatomical region where the surgical procedure will be performed in the current preoperative condition and predicted postoperative condition; and

wherein the rapid prototyping unit is adapted to create a guide for use during the surgical procedure.

8. The system for planning spine surgery of claim 7, wherein the guide is created of material capable of being sterilized for surgery.

9. The system for planning spine surgery of claim 8, wherein the guide is created of epoxy material formed from a mold.

10. The system for planning spine surgery of claim 7, wherein the guide can be used as a template for drilling holes into bone for appropriate attachment of the implant in alignment.

11. The system for planning spine surgery of claim 7 wherein the computer is adapted to suggest revisions to the surgical procedure.

12. The system for planning spine surgery of claim 7 wherein the computer simulates loading of the spine and planned implanted hardware using finite element software.

13. A method of surgically placing a spinal implant in alignment, comprising the steps of:

providing a haptic interface capable of providing force feedback to a user;

providing a computer adapted to simulate a surgical procedure by responding to inputs from the haptic interface and outputting haptic feedback to the haptic interface;

providing a rapid prototyping unit, in communication with the computer, adapted to create a three dimensional model of the anatomical region where the surgical procedure will be performed in its current unoperated condition and predicted postoperative condition;

creating a surgical implantation guide using the model created by the rapid prototyping unit; and

using the surgical implantation guide during surgery to guide the configuration and placement of a spinal implant in a patient.

14. The method of surgically placing a spinal implant in alignment of claim 13, including the step of using the guide as a template to drill attachment holes for implant placement as needed.

15. The method of surgically placing a spinal implant in alignment of claim 14, including providing a guide tool and placing guide rods in the attachment holes such that the guide tool can be used to shape bone for the placement of the spinal implant in alignment.
