INTERLEAVED IMAGING AND TRACKING SEQUENCES FOR ULTRASOUND-BASED INSTRUMENT TRACKING
A method for tracking an interventional medical device in a patient includes interleaving, by an imaging probe external to the patient, a pulse sequence of imaging beams and tracking beams to obtain an interleaved pulse sequence. The method also includes transmitting, from the imaging probe to the interventional medical device in the patient, the interleaved pulse sequence. The method further includes determining, based on a response to the tracking beams received from a sensor on the interventional medical device, a location of the sensor in the patient.
INTRAOPERATIVE IMPLANT AUGMENTATION
Methods and systems of augmenting an implant intraoperatively and preparing a cone for revision surgical procedure are disclosed. A system includes a cutting device, a tracking and navigation system and a cutting system in operable communication with the cutting device and the tracking and navigation system. The cutting device includes a communication system, a cutting element, and a plurality of optical trackers. The tracking and navigation system is configured to detect a location of optical trackers. The control system is configured to cause the tracking and navigation system to detect the location of the cutting device, determine a revised shape for an implant cavity, cause the cutting device to cut the implant cavity to the revised shape, select a shape for a cone to be placed in the revised implant cavity, and machine the cone to the selected shape.
ANATOMICAL MODEL GENERATION
Devices, systems, and methods of the present disclosure are directed to generating three-dimensional surface representations of an anatomic structure such as a heart cavity. More specifically, a three-dimensional surface representation of the anatomic structure is constrained relative to one or more anchor portions corresponding to received input regarding the location of anatomic features of the anatomic structure. The resulting three-dimensional surface representation includes salient features of the anatomic structure and, therefore, can be useful as visualization tool during any of various different medical procedures, including, for example, cardiac ablation.
Systems, methods, and devices for instrument guidance
A system for instrument guidance is disclosed. The system can include an instrument guide device and a transducer system. The instrument guide device can include an instrument guide and an instrument guide bracket that includes a magnet, and the instrument guide bracket can be removably attachable to the instrument guide. The transducer system can include an ultrasound probe bracket that is removably attachable to an ultrasound probe. Further, the instrument guide device can removably attach to the ultrasound probe bracket. The ultrasound probe bracket can further include a first sensor and second sensor. The first sensor can wirelessly track a position of the magnet to determine position data of the instrument guidance system. And the second sensor can provide power or disengage power to the instrument guidance device when the instrument guide is attached or detached, respectively.
Elastography for ligament characterization
Methods and system for characterizing ligament properties using elastography are disclosed. An ultrasound system capable of performing shear wave elasticity imaging and/or supersonic shear imaging may retrieve one or more images from a proposed surgical site. The one or more images may be provided to a surgical planning system that identifies one or more properties of ligaments proximate to the surgical site. Musculoskeletal simulations may be performed using the identified properties to preoperatively identify a surgical plan. Preoperative identification of a surgical plan may enable a surgeon to select from more fine-tuning options for a joint replacement than conventional systems.
ANATOMICAL FEATURE EXTRACTION AND PRESENTATION USING AUGMENTED REALITY
An ultrasound probe captures real-time images of patient anatomy, which are analyzed by a processor to extract salient features pertaining to an anatomical structure. By tracking the location and orientation of the ultrasound probe, a model of that anatomical structure can be created. A visual indication of the position of segments of the anatomical structure can be presented holographically to a user of an augmented reality headset to provide information extracted from the ultrasound imaging, such as holographic display of a model of the anatomical structure at the approximate location of the visual field of the headset corresponding to the physical location of the actual anatomy being viewed by a user, without presenting the entirety of the ultrasound image to the user.
END EFFECTOR IDENTIFICATION IN SURGICAL ROBOTIC SYSTEMS
Systems, methods, and devices are disclosed for end effector identification in robotic surgical systems. A surgical robot can be coupled to an end effector. The system can identify the end effector using data received from the end effector. The system can adjust operation of the surgical system, including the robot arm, based on the data received from the end effector. Data received from or regarding the end effector can include detected characteristics, retrieved characteristics, or data stored on the end effector and communicated to the system. Both the identification and the operation adjustments can be performed automatically such that the system experiences little to no lag or downtime when coupling with different end effectors.
Apparatuses and methods for registering a real-time image feed from an imaging device to a steerable catheter
A method of registering a real-time image feed from an imaging device inserted into a steerable catheter using a navigation system is provided. The method includes inserting the imaging device into a working channel of the steerable catheter and generating a real-time image feed of one or more reference points, wherein the orientation of the reference points is known. The method further includes orienting a handle of the steerable catheter to a neutral position, displaying the real-time image feed on a display of the navigation system, and registering the real-time image feed to the steerable catheter by rotating the displayed image so that the reference points in the real-time image feed are matched to the known orientation of the reference points.
PHYSIOLOGY SENSING INTRALUMINAL DEVICE WITH POSITIONING GUIDANCE AND ASSOCIATED DEVICES, SYSTEMS, AND METHODS
An intraluminal sensing system is provided that includes an intraluminal device. The intraluminal device has a flexible elongate member configured to be positioned within a body lumen of a patient, and an ultrasound sensor at a distal portion of the flexible elongate member. The ultrasound sensor is configured to emit an ultrasound pulse in a longitudinal within the body lumen, and to receive Doppler-shifted echoes from the ultrasound pulse. A processor circuit in communication with the ultrasound sensor is configured to: compute a velocity spectrum of particles moving within the body lumen based on the Doppler-shifted echoes; identify features in the velocity spectrum indicative of a lateral position or angular alignment of the ultrasound sensor within the body lumen; and output, to a display in communication with the processor circuit, positioning guidance for the intraluminal device based on the identified features in the velocity spectrum.
Surgical instrument and method
A surgical instrument comprises a member defining a longitudinal axis and being connectable with a spinal implant. A handle is connected with the member. An image guide is connected with the member for orientation relative to a sensor to communicate a signal representative of a position of the spinal implant. The image guide is rotatable about the axis relative to the member and is disposable in at least one fixed position with the member. Systems, implants, spinal constructs and methods are disclosed.
