Systems and methods for robotic medical system integration with external imaging
A medical robotic system and method of operating such comprises taking intraoperative external image data of a patient anatomy, and using that image data to generate a modeling adjustment for a control system of the medical robotic system (e.g., updating anatomic model and/or refining instrument registration), and/or adjust a procedure control aspect (e.g., regulating substance or therapy delivery, improving targeting, and/or tracking performance).
1. A medical system comprising:
a robotically controllable instrument;
a camera at a distal end of the instrument;
a sensor system configured to determine an intraoperative position of at least the distal end of the instrument;
a display system configured to display images when the distal end of the instrument is positioned within an anatomy of a patient, wherein the images include real-time information regarding the instrument and the anatomy of the patient; and
a processor configured to refine a relationship between the instrument and an anatomical model of the patient based at least in part on both intraoperative external image data for a portion of the anatomy of the patient and intraoperative position data for at least the distal end of the instrument.
2. The medical system of claim 1 wherein the camera is integrally coupled to the instrument.
3. The medical system of claim 1 wherein the camera is removably coupled to the instrument and is configured to be deployed via a working lumen of the instrument.
4. The medical system of claim 1 wherein the real-time information regarding the instrument and the anatomy of the patient comprises intraoperative images from the camera.
5. The medical system of claim 1 wherein the real-time information regarding the instrument and the anatomy of the patient comprises information regarding the position of at least the distal end of the instrument within the anatomy of the patient.
6. The medical system of claim 1 wherein the instrument further comprises a plurality of steering cables extending at least partially between the distal end of the instrument and an interface, wherein the interface is configured to couple the steering cables to a driver assembly that is part of a robotic arm cart.
7. The medical system of claim 6 further comprising a hand-operated controller configured to control the driver assembly.
8. The medical system of claim 1 wherein the sensor system is an electromagnetic (EM) sensor system, and the intraoperative external image data is received from a fluoroscopic C-arm device.
9. The medical system of claim 1 wherein the sensor system is a shape sensor system, and the intraoperative external image data is received from a cone-beam CT scanner.
10. The medical system of claim 1 further comprising fiducial elements that are identifiable in the intraoperative external image data to provide a common registration reference.
11. The medical system of claim 1 wherein the display system is further configured to indicate a pose of the distal end of the instrument relative to a target node.
12. The medical system of claim 1 wherein the processor is further configured to use the intraoperative external image data to refine a registration between the anatomical model of the anatomy of the patient and the anatomy of the patient.
13. The medical system of claim 1 wherein the processor is further configured to use the intraoperative external image data to improve a registration between the instrument and the anatomy of the patient.
14. The medical system of claim 1 wherein the processor is further configured to perform a tomographic reconstruction based on the intraoperative external image data.
15. The medical system of claim 14 wherein the processor is further configured to use the tomographic reconstruction to characterize the relationship between the distal end of the instrument and an anatomical target.
16. The medical system of claim 1 wherein the processor is further configured to use instrument pose data extracted from the intraoperative external image data to update a registration of the instrument to the anatomical model.
17. The medical system of claim 1 wherein the processor is further configured to use instrument pose data extracted from the intraoperative external image data to update the anatomical model.
18. The medical system of claim 1 wherein the processor is further configured to use the intraoperative external image data in conjunction with the anatomical model to provide a representation of an immediate intraoperative environment.
