SYSTEMS AND METHODS FOR IMPLANTATION OF SPINAL PLATE
A method includes tracking three or more bones of a patient, planning a planned alignment between the three or more bones, and creating an implant placement plan based on the planned alignment. The implant placement plan includes a placement of a plate across the three or more bones. The method also includes robotically assisting preparation of the three or more bones to receive the plate in accordance with the implant placement plan.
1 . A method, comprising:
tracking three or more bones of a patient;
planning a planned alignment between the three or more bones;
creating an implant placement plan based on the planned alignment, the implant placement plan comprising a placement of a plate across the three or more bones; and
robotically assisting preparation of the three or more bones to receive the plate in accordance with the implant placement plan.
2 . The method of claim 1 , wherein the three or more bones comprise a plurality of vertebrae.
3 . The method of claim 1 , wherein planning the planned alignment comprises adjusting a relationship between a plurality of bones of the three or more bones to a desired rotation between the plurality of bones.
4 . The method of claim 1 , wherein creating the implant placement plan comprises planning a first cavity to be sculpted at a first bone of the three or more bones and a second cavity to be sculpted at a second bone of the three or more bones, the first cavity to receive a first portion of the plate and the second cavity to receive a second portion of the plate.
5 . The method of claim 4 , wherein creating the implant placement plan comprises planning the first cavity and the second cavity such that a top surface of the plate is planned to be substantially flush with surfaces of the first bone and the second bone.
6 . The method of claim 1 , wherein robotically assisting preparation of the three or more bones to receive the plate comprises:
tracking a pose of a robotic device relative to one or more of the three or more bones; and
controlling the robotic device based on the pose of the robotic device relative to the one or more of the three or more bones.
7 . The method of claim 6 , wherein robotically assisting preparation of the three or more bones comprises providing force feedback via the robotic device.
8 . The method of claim 1 , wherein creating the implant placement plan comprises defining a virtual cutting boundary; and
robotically assisting preparation of the three or more bones includes confining a pose of a robotic device based on the virtual cutting boundary.
9 . The method of claim 8 , wherein the virtual cutting boundary corresponds to one or more dimensions of the plate.
10 . The method of claim 1 , wherein robotically assisting preparation of the three or more bones comprises creating a hole in a first bone of the three or more bones, the hole configured to receive an engagement member to engage the plate with the first bone.
11 . The method of claim 1 , wherein creating the implant placement plan comprises selecting a plate model from a database of plate models, the plate model corresponding to a shape and a size of the plate to be used in the implant placement plan.
12 . A robotically-assisted surgical system, comprising:
a robotic device configured to assist modification of at least one of three or more bone structures; and
circuitry programmed to:
obtain an implant placement plan based on a planned alignment between the three or more bone structures, the implant placement plan comprising a positioning of an implant spanning the three or more bone structures; and
controlling the robotic device to assist preparation of the three or more bone structures to receive the implant in accordance with the implant placement plan.
13 . The robotically-assisted surgical system of claim 12 , wherein the three or more bone structures comprise a plurality of vertebrae.
14 . The robotically-assisted surgical system of claim 12 , wherein the implant is a plate.
15 . The robotically-assisted surgical system of claim 12 , wherein the implant placement plan includes a desired rotation between a plurality of bones of the three or more bone structures.
16 . The robotically-assisted surgical system of claim 12 , wherein the implant placement plan comprises planning a first cavity to be sculpted at a first bone of the three or more bone structures and a second cavity to be sculpted at a second bone of the three or more bone structures, the first cavity to receive a first portion of the implant and the second cavity to receive a second portion of the implant.
17 . The robotically-assisted surgical system of claim 12 , wherein the circuitry is further programmed to:
determine a pose of the robotic device relative to one or more of the three or more bone structures; and
control the robotic device based on the pose of the robotic device relative to the one or more of the three or more bone structures.
18 . A surgical system, comprising:
a tracking system configured to track at least one of three or more bones of a patient;
a robotic device configured to assist modification of the at least one of the three or more bones; and
circuitry programmed to:
obtain tracking data of the at least one of the three or more bones;
create an implant placement plan based on a planned alignment between the three or more bones, the implant placement plan comprising a placement of an implant spanning the three or more bones; and
control the robotic device to assist preparation of the three or more bones to receive the implant in accordance with the implant placement plan.
19 . The surgical system of claim 18 , wherein the implant placement plan includes a desired rotation between a plurality of bones of the three or more bones.
20 . The surgical system of claim 18 , wherein the implant is a plate.
