Systems and methods for providing alignment of instruments and/or prostheses in various surgical operations are provided herein. The systems and methods generally include one or more sensors coupled to a patient's bones or other surgical tools, the sensors can detect their position and orientation in space and communicate this information to a processor. The processor can utilize the information to display data to a surgeon or other user regarding the position, angle, and alignment of a patient's bones, surgical tools, and prostheses. Further, the one or more sensors can be aligned to the patient's anatomy using a patient-specific alignment guide that interfaces with a portion of the patient's anatomy in a single position/orientation.

A LUS robotic surgical system is trainable by a surgeon to automatically move a LUS probe in a desired fashion upon command so that the surgeon does not have to do so manually during a minimally invasive surgical procedure. A sequence of 2D ultrasound image slices captured by the LUS probe according to stored instructions are processable into a 3D ultrasound computer model of an anatomic structure, which may be displayed as a 3D or 2D overlay to a camera view or in a PIP as selected by the surgeon or programmed to assist the surgeon in inspecting an anatomic structure for abnormalities. Virtual fixtures are definable so as to assist the surgeon in accurately guiding a tool to a target on the displayed ultrasound image.

Example systems and techniques for denervation, for example, renal denervation. In some examples, a processor determines one or more tissue characteristics of tissue proximate a target nerve and a blood vessel. The processor may generate, based on the one or more tissue characteristics, an estimated volume of influence of denervation therapy delivered by a therapy delivery device disposed within the blood vessel. The processor may generate a graphical user interface including a graphical representation of the tissue proximate the target nerve and the blood vessel and a graphical representation of the estimated volume of influence.

In at least some aspects, an instrument port for introducing an instrument into a surgical site comprises: a port body having: an instrument channel extending through the port body; and a plurality of fluid flush channels each separate from one another and the instrument channel, each extending along a major portion of the port body and in fluid communication with the instrument channel; and a bulb comprising a bulb channel extending through the bulb, the bulb channel aligned with the instrument channel, wherein the bulb channel and instrument channel are configured to receive the instrument.

A C-arm, or a mobile intensifier device, is one example of a medical imaging device that is based on X-ray technology. Because a C-arm device can display high-resolution X-ray images in real time, a physician can monitor progress at any time during an operation, and thus can take appropriate actions based on the displayed images. Monitoring the images, however, is often challenging during certain procedures, for instance during procedures in which attention must be paid to the patient's anatomy as well as a medical imaging device display. In an example, a surgical instrument assembly includes a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The display can be configured to display visual information comprising X-ray images generated by a medical imaging device, depth gauge information generated by a depth gauge coupled to the surgical instrument, and trajectory information associated with various intramedullary nailing operations.

A biological tissue inspection apparatus is disclosed. The biological tissue inspection apparatus comprises a stage and a probe. The probe comprises an optical imaging device, an optical interference detector, and a light guide. The probe acquires data regarding optical images and optical interference, through the optical imaging device and the optical interference detector. The stage or the probe moves such that a selected area of the inspection object is positioned in the FOV of the optical imaging device and of the optical interference detector. The light guide is configured such that illumination light from the optical imaging device and measurement light from the optical interference detector are coaxially emitted to the inspection object.

A method and system is disclosed for analyzing image data of a subject. The image data can be collected with an imaging system in a selected manner and/or motion. The image data may include selected overlap and be acquired with an imaging system that generates a plurality of perspectives for more than one location. An automatic system and method may then define or identify various features and/or allow for registration for alternative image data.

A navigated surgery system includes at least one processor that is operative to obtain a 2D medical image slice of anatomical structure of a patient. The operations further obtain a 3D graphical model of anatomical structure. The operations determine a pose of a virtual cross-sectional plane extending through the 3D graphical model of the anatomical structure that corresponds to the anatomical structure of the 2D medical image slice. The operations control the XR headset to display the 2D medical image slice of the anatomical structure of the patient, display the 3D graphical model of the anatomical structure, and display a graphical object oriented with the pose relative to the 3D graphical model of the anatomical structure.

A system and method for image guidance providing improved perception of a display object in a rendered scene for medical device navigation. The system can receive emplacement information associated with a medical device and determine an emplacement of a display object associated with the medical device. The system can further identify a selected surface of the display object and cause a display to display a selective-transparency rendering of the selected surface.

A surgical access assembly comprises a trocar and a surgical instrument. The trocar comprises a housing and an access tube extending distally from the housing. The housing comprises a hollow light emitter. The housing and the access tube define a lumen extending through the housing and the access tube. The hollow light emitter is configured to project light in the lumen. The surgical instrument comprises an end effector and a shaft extending proximally from the end effector. The shaft comprises an optical receiver positioned within reach of the light from the hollow light emitter. The shaft further comprises a light guide extending from the optical receiver along at least a portion of the shaft toward the end effector.
