Robotic navigation of robotic surgical systems

In certain embodiments, the systems, apparatus, and methods disclosed herein relate to robotic surgical systems with built-in navigation capability for patient position tracking and surgical instrument guidance during a surgical procedure, without the need for a separate navigation system. Robotic based navigation of surgical instruments during surgical procedures allows for easy registration and operative volume identification and tracking. The systems, apparatus, and methods herein allow re-registration, model updates, and operative volumes to be performed intra-operatively with minimal disruption to the surgical workflow. In certain embodiments, navigational assistance can be provided to a surgeon by displaying a surgical instrument's position relative to a patient's anatomy. Additionally, by revising pre-operatively defined data such as operative volumes, patient-robot orientation relationships, and anatomical models of the patient, a higher degree of precision and lower risk of complications and serious medical error can be achieved.

20230363838 · 2023-11-16 ·

Techniques for retracting an instrument into an entry guide include an entry guide manipulator configured to support an entry guide and an instrument manipulator configured to support an instrument. The robotic system is configured to receive a command indicating a commanded movement of the entry guide in a direction parallel to an insertion axis of the entry guide; in response to the commanded movement of the entry guide being greater than a threshold distance in the direction parallel to the insertion axis, cause a response comprising one or more actions selected from the group consisting of: movement, using the instrument manipulator, of one or more rotational joints of the instrument external to the entry guide toward a distal end of the entry guide; and actuation of the one or more rotational joints to straighten the instrument so that the instrument can be retracted into the entry guide.

SYSTEMS, METHODS, AND DEVICES FOR REGISTERING AND TRACKING ORGANS DURING INTERVENTIONAL PROCEDURES
20230355321 · 2023-11-09 ·

Systems, methods, and devices are provided for assisting or performing guided interventional procedures using. The system uses pre-procedure scans of a patient's anatomy to identify targets and critical structures. A measurement device containing position indicating elements or fiducials is placed in a pre-existing or physician created conduit or lumen whose geometry is known from a scan. During a procedure, the pre-procedure scans may be registered to the patient using the position indicating elements or fiducials and the geometry of the conduit. This registration may be used in an intervention to guide instruments that can obtain diagnostic information or provide therapy to the identified targets. During the procedure, the position indicating elements may be used to dynamically compensate for motion to further improve accuracy.
