ACTIVE DISTAL TIP DRIVE
A method and system of correcting alignment of catheter relative to a target including receiving signals from an inertial measurement unit located at a distal end of a catheter, determining movement of the distal end of the catheter caused by physiological forces, receiving images depicting the distal end of the catheter and the target, identifying the distal end of the catheter and the target in the images, determining an orientation of the distal end of the catheter relative to the target and articulating the distal tip of the catheter in response to the detected movement to achieve and maintain an orientation towards the target such that a tool extended from an opening at the distal end of the catheter would intersect the target.
COMPUTER-ASSISTED NEEDLE INSERTION SYSTEM AND COMPUTER-ASSISTED NEEDLE INSERTION METHOD
A computer-assisted needle insertion system and a computer-assisted needle insertion method are provided. The computer-assisted needle insertion method includes: obtaining a first machine learning (ML) model and a second ML model; obtaining a computed tomography (CT) image and a needle insertion path, generating a suggested needle insertion path according to the first ML model, the CT image, and the needle insertion path, and instructing a needle to approach a needle insertion point on a skin of a target, wherein the needle insertion point is located on the suggested needle insertion path; obtaining a breath signal of the target, and estimating whether a future breath state of the target is normal according to the second ML model and the breath signal; and outputting a suggested needle insertion period according to the breath signal in response to determining that the future breath state is normal.
SYSTEMS AND METHODS FOR SURGICAL PORT POSITIONING
A method for robot-assisted minimally invasive surgery involves calculating, based on a surgical plan, an insertion vector for an MIS port; causing a robotic arm to hold the MIS port in a pose that corresponds to the insertion vector; detecting, with a sensor on the robotic arm, a force applied to the robotic arm via the MIS port; maintaining the MIS port in the pose when the detected force is lower than a predetermined threshold; and generating an alert when the detected force exceeds the predetermined threshold.
SYSTEMS AND METHODS FOR REGISTRATION OF INTRA-BODY ELECTRICAL READINGS WITH A PRE-ACQUIRED THREE DIMENSIONAL IMAGE
There is provided a method of displaying a pre-acquired three dimensional (3D) image of at least a portion of an organ of a patient, the method comprising: receiving a plurality of electrical readings, each from a different electrode mounted on a catheter inside the portion of the organ of the patient, wherein the electrodes are mounted on the catheter at known distances from each other, transforming the plurality of electrical readings to a corresponding plurality of image points using a mapping transformation that transforms each electrical reading of the catheter from inside the portion of the organ of the patient to an anatomically corresponding image point in the 3D image based on the known distances, and displaying the 3D image with a marking of at least one of the plurality of image points.
PROBE-CAVITY MOTION MODELING
The present disclosure provides systems, apparatuses and methods that provide probe-cavity location and motion data based on probe location and respiration data.
SYSTEM FOR POSITION AND PROCESS VERIFICATION IN COMPUTER ASSISTED SURGERY
Systems and methods for accurate determination of the position of an anatomic part of a subject in robotic assisted image-based surgery, using an inertial measurement unit (IMU) to determine the position and orientation of the anatomical part of the subject. The intrinsic drift of the IMU, which would make the IMU position measurements inaccurate, can be reset to zero regularly, at points of time when the subject's body is stationary. This can be achieved when motion from the subject's breathing and from the heartbeat are essentially zero. Such positions occur respectively when the respiratory signal shows the position of the breathing cycle to be at the end of the expiration phase, and the heartbeat signal represents a time in the diastole period of the subject's electrocardiographic cycle. When these two signal moments coincide, the IMU is essentially stationary, and its drift reset to zero.
SYNCHRONISATION DEVICE AND METHOD FOR DETERMINING AN INSTANT OF THE RESPIRATORY CYCLE OF A PATIENT, AND ASSEMBLY COMPRISING A MEDICAL ROBOT
The invention relates to a synchronization device for determining an instant of the respiratory cycle of a patient in order to assist a medical intervention on said patient. This device comprises: a locating device, a patient reference, intended to be positioned on the body of the patient, and comprising radio-opaque markers, at least one locating element configured to be detectable by the locating device, and an X-ray detector intended to cooperate with an X-ray imaging device, a control unit for recording and processing data from the locating device and the patient reference. The invention likewise relates to a method for determining an instant of the respiratory cycle of a patient in order to assist a medical intervention on said patient.
END EXPIRIUM IDENTIFICATION METHODS, SYSTEMS, AND PROCESSES
The present disclosure provides systems, apparatuses and methods that identify end expirium data based on catheter movement data.
Respiratory Compensated Robot for Liver Cancer Treatment
A robotic platform system having a lower stage with a motorized cartesian carriage, an upper stage, and a needle insertion module that connects both stages together.
Systems and methods for anatomic motion compensation
A medical system includes an interventional instrument and a control system including one or more processors. The control system is configured to: receive a pose dataset for a point on the instrument retained in compliant movement with a cyclically moving patient anatomy for a plurality of time parameters during a cyclical anatomical motion; determine a set of pose differentials for the identified point with respect to a reference point at each time parameter; identify a periodic signal for the anatomical motion from the set of pose differentials; generate a command signal indicating an intended movement of the instrument relative to the patient anatomy; adjust the command signal to include an instruction for a cyclical instrument motion based on a phase of the anatomical motion; and cause the intended movement of the instrument relative to the patient anatomy based on the adjusted command signal to compensate for the anatomical motion.
