Femoral medial condyle spherical center tracking

Systems and methods for femoral medial condyle spherical center identification and tracking are described herein. Once the spherical center of the medial condyle is identified, the spherical center is tracked using a pin or internal reference. The spherical center may be used to provide a key kinematic motion reference, such as when the medial condyle is adjusted during a surgical procedure. The tracking may be used to provide optical tracking, inertial tracking, or other tracking. In contrast with surface-mounted optical trackers, the spherical center tracking is not lost during resection (e.g., removal) of a bone surface. Tracking the medial condyle spherical center may reduce or eliminate the need for a surface-mounted optical tracker or preoperative 3-D modeling or of the joint.

Techniques for modifying tool operation in a surgical robotic system based on comparing actual and commanded states of the tool relative to a surgical site

Systems and methods for operating a robotic surgical system are provided. The system comprises a surgical tool for interacting with a surgical target, a manipulator comprising a plurality of links and supporting the tool, a navigation system comprising a manipulator tracker coupled to the manipulator and a patient tracker coupled to the surgical target and a localizer for monitoring states of the trackers. A controller determines commanded states for moving the tool relative to the surgical target using data (filtered according to a first filter length) from the manipulator and/or navigation system. The controller determines actual states of the tool while commanding the tool relative to the surgical target using data (filtered according to a second filter length being shorter than the first filter length) from the manipulator and/or navigation system. The controller compares the commanded and actual states and modifies tool operation based on an outcome of the comparison.

Contact force compensation in a robot manipulator

A robotic manipulator is attachable to a proximal end of a medical instrument. A processor linked to the manipulator transmits control signals to the manipulator to cause the manipulator to displace the medical instrument to achieve a desired position and orientation of the medical instrument. A contact force sensor is disposed on the medical instrument and linked to the processor. The control signals are issued by the processor responsively to force indications received from the contact force sensor.

SYSTEMS AND METHODS FOR REGISTRATION OF LOCATION SENSORS

Provided are systems and methods for registration of location sensors. In one aspect, a system includes an instrument and a processor configured to provide a first set of commands to drive the instrument along a first branch of the luminal network, the first branch being outside a path to a target within a model. The processor is also configured to track a set of one or more registration parameters during the driving of the instrument along the first branch and determine that the set of registration parameters satisfy a registration criterion. The processor is further configured to determine a registration between a location sensor coordinate system and a model coordinate system based on location data received from a set of location sensors during the driving of the instrument along the first branch and a second branch.
