Systems and methods are described herein for supporting medical procedures by allowing representatives access to real-time information concerning an ongoing medical procedure and providing for communications concerning how to make use of medical devices during such medical procedures. Such systems and methods may, for example, provide live streaming and interactive capabilities for communication between medical personnel and a medical device representative.

Systems and methods of visualizing a current view of a tool relative to a lesion by processing current fluoroscopic images from a current fluoroscopic sweep occurring after an initial fluoroscopic sweep. The processing includes determining the locations and/or orientations of a tool and a lesion in a current 3D reconstruction of the current fluoroscopic images or in a subset of the current fluoroscopic images, generating a 3D rendering based on the locations and/or orientations of the tool and the lesion, and displaying the 3D rendering. The locations and/or orientations of the tool and the lesion may be obtained from a user interface enabling a user to mark the current locations and/or orientations in the current 3D reconstruction or in a subset of the current fluoroscopic images, or by segmenting the current 3D reconstruction or a subset of the current fluoroscopic images.

An exemplary method of displaying an intraoperative image of a surgical site comprises: receiving a plurality of images captured by a plurality of in-light cameras integrated into one or more surgical light units illuminating the surgical site, wherein the plurality of images capture the surgical site from a plurality of different perspectives; identifying an obstruction to the surgical site in an image of the plurality of images; responsive to identifying the obstruction, generating a composite image based on a set of the plurality of images, wherein the composite image excludes the obstruction; and displaying the composite image as the intraoperative image of the surgical site.

A configurable pathway deviation indication system for medical device placement includes one or more user-adjustable pathway boundaries and an indication activated upon reaching or breaching of any of the pathway boundaries. The system may include a medical device configured to be inserted into a patient; a location transmitter configured to transmit a signal related to a position of the medical device; and a detector device configured to receive information related to the patient's body and the location transmitter. The system may be operatively coupled to the location transmitter and the at least one detector device. The system may further include a display and a computing system comprising one or more processors and or more non-transitory computer-readable media. The system can display the position of the location transmitter; determine if the position of the location transmitter reaches any pathway boundaries; and provide the indication when the pathway boundary is breached and/or approached.

An adaptive guidance system providing procedure instruction data to a user using an equipment system to perform a procedure. The guidance system gathers user condition data (e.g., electroencephalography (EEG) data, electrocardiography (EKG) data, near infrared skin spectroscopy data, skin galvanometry data, heart rate data, heart rate variability data, respiratory data, radiation dosimetry data, eye movement data, pupil dilation data, or two or more thereof) related to a user state, and generates, re-generates, or modifies the procedure instruction data if the user condition data indicates the user is in a state of physical, mental, or emotional impairment, such as fatigue, cognitive overload, radiation exposure, toxin exposure, stress, illness, depression, intoxication by alcohol or a drug, a mismatch between the user's perceived skill level and true skill level, or two or more thereof. By modifying the procedure instruction data based on the user condition data, the likelihood of the user successfully performing the procedure increases.

This disclosure describes an interactive augmented reality system for improving surgeon's view and context awareness during laparoscopic and video assisted surgeries. Instead of purely relying on computer vision algorithms for image registration between pre-operation (or intra-operation) images/models and later intra-operation scope images, the system can implement an interactive mechanism where surgeons may provide supervised information in initial calibration phase of the augmented reality function, thus achieving high accuracy in image registration. Besides the initialization phase before operation starts, interaction between surgeon and the system can also happens during the surgery. Specifically, patient tissue might move or deform during surgery, caused by for example cutting. The augmented reality system can re-calibrate during surgery when image registration accuracy deteriorates, by seeking additional supervised labeling from surgeons. The augmented reality system can improve surgeon's view during surgery, by utilizing surgeon's guidance sporadically to achieve high image registration accuracy.

A computer program element and a device are provided for processing a 2D projection image generated during a procedure of fracture treatment of a bone. The computer program element comprises sets of instructions for detecting the reference body in the 2D projection image, detecting at least one element out of the group consisting of an instrument, an implant and an anatomical structure in the 2D projection image, and identifying a current state of the element, determining a state of progress of the procedure of fracture treatment, and providing information regarding steps to be performed next.

The invention discloses a three-dimensional atrial septal puncture method including positioning the heart from a body surface by a three-dimensional projection positioning method and displaying interventional instruments by the three-dimensional system and guiding the same into a heart cavity. The method also includes constructing a right atrium three-dimensional model by delivering a catheter with a positioning device to the right atrium and reconstructing and fusing pre-operative image data by the three-dimensional system. The method also includes setting parameters, connecting an interventional operating device with a pressure sensor tail wire and an electrode tail wire, and displaying a guidewire or a puncture needle. The method includes delivering and positioning the long sheath, analyzing and marking the fossa ovalis position by a structure and potential method. The method also includes analyzing the pressure difference between the left atrium and the right atrium, and judging whether the puncture is successful.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

In one embodiment, the present disclosure relates to a method of evaluating soft tissue tension surrounding a hip of a patient using navigation and software to track positions of the femur and a pelvis of the patient in real time. The method begins with intra-operative reduction of a femoral implant into an acetabulum of a patient and retrieval of first coordinates of a femoral head center of the femoral implant when the femoral implant is in a reduced position. Performance of a shuck test follows where the femur is distracted relative to the acetabulum. Retrieval of second coordinates of the femoral head center occurs when the femoral implant is distracted from the acetabulum, and a difference between the first coordinates and the second coordinates in a coronal plane is used to determine a shuck length vector.
