Abstract

A method of performing a computer-assisted surgical procedure on the spine of a patient comprising the steps of: planning, on a computer, a surgical procedure based on at least one of two- and three-dimensional images of the patient's spine; affixing a robotic assembly over an operative region of the patient; determining, with a computer in communication with the robotic assembly, a desired trajectory of a surgical tool along at least one of an access path and an implant path towards the surgical target site; and placing at least a portion of the surgical tool through the aperture along said desired trajectory along at least one of said access path and said implant path towards the surgical target site.

First claim

We claim:

1 . A method of performing a computer-assisted surgical procedure on the spine of a patient comprising the steps of:
planning, on a computer, a surgical procedure based on at least one of two- and three-dimensional images of the patient's spine, wherein said planning comprises determining at least one of an access path and an implant path towards a surgical target site; affixing a robotic assembly over an operative region of the patient, the robotic assembly comprising at least one aperture and being adapted to receive a portion of at least one surgical tool therethrough and operable to produce coordinated movements in six degrees of freedom to reposition the aperture relative to the operative region; determining, with a computer in communication with the robotic assembly, a desired trajectory of a surgical tool along at least one of said access path and said implant path towards the surgical target site; and placing at least a portion of the surgical tool through the aperture along said desired trajectory along at least one of said access path and said implant path towards the surgical target site.

2 . The method of claim 1 , wherein the surgical procedure is one of open and minimally-invasive.

3 . The method of claim 1 , wherein the access path is one of a posterior and a posterior-lateral approach to the spine.

4 . The method of claim 1 , wherein the implant path is to a lateral aspect of the spine.

5 . The method of claim 1 , wherein the step of planning further includes determining the size of a spinal implant.

6 . The method of claim 5 , wherein the spinal implant is an intervertebral implant.

7 . The method of claim 1 , wherein the operative region of the patient is posterior.

8 . The method of claim 1 , wherein the aperture is a cannula.

9 . The method of claim 9 , wherein the cannula comprises a multi-cannula assembly.

10 . The method of claim 1 , wherein the robotic assembly is powerable by an electric motor.

11 . The method of claim 10 , wherein the electric motor is controlled by a multifunctional controller via a control cable.

12 . The method of claim 1 , wherein the surgical tool comprises one of a milling head, a forceps tool, a forceps finger, a fluid dispenser tool, a pick and place tool, an articulated element, an inflation tool, a gauging tool, and a cutting tool.
