Abstract

Methods, apparatuses, and systems for performing robotic joint arthroscopic surgery are disclosed. The disclosed systems use a surgical robot network that receives medical images of a patient and generates a 3D rendering of the various medical images. A surgeon or physician is enabled to select workflow objects (such as various tools). The workflow objects can be selected in a sequence for performing actions on the 3D rendering. Data related to the workflow objects and actions in relation to the 3D rendering are stored. The surgeon or physician is enabled to select and perform various repairing techniques and input calculations of the actions performed. The user inputs, workflow objects, and actions with respect to the 3D rendering are sent to a surgical robot for performing robotic joint arthroscopic surgery.

First claim

What is claimed is:

1. A computer-implemented method for performing surgery using a robotic surgical system, the method comprising:
obtaining pre-operative image data of a patient;
identifying at least one of a pre-operatively damaged ligament or a pre-operatively damaged tendon associated with instability of a joint of the patient based on the pre-operative image data;
generating a pre-operative three-dimensional virtual model representing anatomy in the pre-operative image data, wherein the pre-operative three-dimensional virtual model includes the at least one of the pre-operatively damaged ligament or the pre-operatively damaged tendon;
receiving a selection of a surgical procedure from at least one user; and
controlling a surgical robot to robotically perform at least a portion of the selected surgical procedure according to a surgical plan that is dynamically modified intraoperatively based on intraoperative patient data by:
receiving surgical repairing input from the at least one user, wherein the surgical repairing input includes a selected tool and a plurality of surgical repairing steps for repairing the at least one of the pre-operatively damaged ligament or the pre-operatively damaged tendon,
after the surgical robot performs at least one of the plurality of surgical repairing steps on the patient, intraoperatively generating a post-operative three-dimensional virtual model representing a repaired joint by virtually performing the plurality of surgical repairing steps, which have not been performed on the patient, on a real-time three-dimensional virtual model using:
capabilities of the surgical robot, and
the selected tool,
wherein the real-time three-dimensional virtual model represents anatomy in intraoperative image data obtained after the surgical robot performs the at least one of the plurality of surgical repairing steps on the patient, and

intraoperatively simulating post-operative dynamic behavior of the repaired joint using the post-operative three-dimensional virtual model,

displaying, via a user device, the simulated post-operative dynamic behavior of the repaired joint for the at least one user to evaluate joint functionality of the repaired joint,
receiving at least one joint functionality parameter from the at least one user,
determining, based on the at least one joint functionality parameter, a bone-to-ligament parameter to increase stability of the repaired joint in the post-operative three-dimensional virtual model to maintain a threshold joint functionality for the repaired joint, and
intraoperatively modifying the surgical plan, executable by the robotic surgical system, based on the intraoperatively simulated post-operative dynamic behavior of the repaired joint and the bone-to-ligament parameter to robotically perform, using the surgical robot, surgical repairing on the patient according to the received surgical repairing input.

2. The computer-implemented method of claim 1 , further comprising:
determining a plurality of candidate surgical steps for the selected surgical procedure;
receiving a selection of at least one of the candidate surgical steps by the user; and
generating a simulation of the selected at least one of the candidate surgical steps using the post-operative three-dimensional virtual model to enable receiving of the surgical repairing input, which represents suturing of anatomical elements of the patient.

3. The computer-implemented method of claim 2 , wherein the surgical repairing input includes anchor parameters for anchors and suturing parameters for suturing together the anchors.

4. The computer-implemented method of claim 1 , further comprising:
analyzing, using at least one machine-learning algorithm, the patient data to determine one or more ligament-attachment joint stabilization steps based on prior patient data, wherein the one or more ligament-attachment joint stabilization steps increase the stability of a joint of the patient; and
determining the surgical step for achieving the one or more ligament-attachment joint stabilization steps, wherein the surgical plan includes the surgical step.

5. The computer-implemented method of claim 1 , further comprising determining one or more implantation steps according to the selection of the surgical procedure.

6. The computer-implemented method of claim 1 , further comprising receiving at least one procedure parameter, wherein the at least one procedure parameter includes one or more target outcome anatomical metrics, specialist information, at least one implantation force, cost of surgery, a time of recovery, or success rate of the surgery.

7. The computer-implemented method of claim 1 , further comprising:
generating multiple post-operative simulations based on the post-operative three-dimensional virtual model;
for each of the post-operative simulations, evaluating one or more patient outcomes; and
selecting one of post-operative simulations based the one or more patient outcomes, wherein the surgical plan is designed to achieve the one or more patient outcomes.

8. The computer-implemented method of claim 1 , further comprising:
displaying the post-operative three-dimensional virtual model with the virtually performed plurality of surgical repairing steps, which have not been performed on the patient;
receiving user approval of at least one of the plurality of surgical repairing steps; and
determining one or more predicted outcomes based on the user approved plurality of surgical repairing steps.

9. A robotic surgical system, comprising:
one or more computer processors; and
a non-transitory computer-readable storage medium storing computer instructions, which when executed by the one or more computer processors cause the robotic surgical system to perform a process including:
obtaining pre-operative image data of a patient;
identifying at least one of a pre-operatively damaged ligament or a pre-operatively damaged tendon associated with instability of a joint of the patient based on the pre-operative image data;
generating a pre-operative three-dimensional virtual model representing anatomy in the pre-operative image data, wherein the pre-operative three-dimensional virtual model includes the at least one of the pre-operatively damaged ligament or the pre-operatively damaged tendon;
receiving a selection of a surgical procedure from at least one user; and
controlling a surgical robot to perform at least a portion of the selected surgical procedure according to a surgical plan that is dynamically modified intraoperatively based on intraoperative patient data by:
receiving surgical repairing input from the at least one user, wherein the surgical repairing input includes a selected tool and a plurality of surgical repairing steps for repairing the at least one of the pre-operatively damaged ligament or the pre-operatively damaged tendon,
