Surgical instruments and system and methods for using surgical instruments are disclosed. A surgical instrument comprises an end effector comprising an ultrasonic blade and clamp arm, an ultrasonic transducer, and a control circuit. The ultrasonic transducer ultrasonically oscillates the ultrasonic blade in response to a drive signal from a generator. The end effector receives electrosurgical energy to weld tissue. The control circuit determines a resonant frequency measure indicative of a thermally induced change in resonant frequency and a electrical continuity measure; calculates a weld focal point based on the determined measures, controls closure of the clamp arm to vary a pressure applied by the clamp arm to provide a threshold control pressure to the tissue loaded into the end effector, and maintains a gap between the ultrasonic blade and clamp arm at a point proximal to the proximal end of the tissue. Pressure is varied based on corresponding weld focal point.

Apparatuses and methods for performing orthodontic treatment planning are provided. Virtual/Augmented Reality devices can be used to virtually manipulate patient's teeth, modify virtual models of the patient's teeth, analyze the fit of a dental appliance on the patient's teeth, analyze the position of attachment sites for dental appliances, and provide overlays showing forces applied to the patient's teeth. The VR/AR devices can be used by physicians and/or the patient to provide and display treatment planning.

Certain aspects relate to systems and techniques for a patient platform system that includes a table and one or more kinematic chains that are coupled to the table. The table includes a rigid base and a table top that is movable relative to the rigid base. One or more processors initiate first movement of the table top relative to the rigid base in accordance with a user request, and move the one or more kinematic chains relative to the rigid base in coordination with the first movement of the table top such that one or more preset conditions are maintained during the first movement of the table top.

Methods, apparatuses, and systems for autonomous surgical robot evolution and handoff for manual operation are disclosed. A robotic surgical system performs surgery and is controlled jointly by an artificial intelligence (AI) and a surgeon. The surgeon can perform the entire surgery or can alternatively allow the AI to control the surgical robot to perform a part of or the entirety of the surgery. The AI is trained using data from previous surgeries, can provide indication to the surgeon when it has been sufficient trained to take over parts of a surgery, and can prompt the surgeon when there is insufficient training data for the AI to continue. Alternatively, a supervising surgeon can manually take back control of the surgical robot from the AI.

Spinal correction surgical techniques and methodologies for correction of scoliosis using non fusion anterior scoliosis correction, including soft tissue releases, unique correction techniques such as de-rotation, and unique single and dual anchor screw/cord applications.

Embodiments described herein provide various examples of monitoring adverse events in the background while displaying a higher-resolution surgical video on a lower-resolution display device. In one aspect, a process for detecting adverse events during a surgical procedure can begin by receiving a surgical video. The process then displays a first portion of the video images of the surgical video on a screen to assist a surgeon performing the surgical procedure. While displaying the first portion of the video images, the process uses a set of deep-learning models to monitor a second portion of the video images not being displayed on the screen, wherein each deep-learning model is constructed to detect a given adverse event among a set of adverse events. In response to detecting an adverse event in the second portion of the video images, the process notifies the surgeon of the detected adverse event to prompt an appropriate action.

A method for performing image-guided embryo transfer for in vitro fertilization includes performing a pre-operative magnetic resonance imaging (MRI) scan of a subjects pelvic region to yield a first MRI image dataset. A computer applies a segmentation routine to the first MRI image dataset to yield segment data which is then used by the computer to create an anatomical model of the subjects pelvic region. The computer determines an optimal implant location based on the anatomical model and creates a three-dimensional rendering of the optimal implant location based on the first MRI image dataset.

Methods, apparatuses, and systems for performing robotic surgery in an extended-reality (XR) surgical simulation environment are disclosed. A patient anatomical model is generated. An XR surgical simulation environment is generated that includes the patient anatomical model. The XR surgical simulation environment is configured to enable the user to virtually perform surgical steps on the patient anatomical model. Anatomical mapping input is received from a user viewing the patient anatomical model. Confidence-score augmented-reality (AR) mapping is performed to meet a confidence threshold for a procedure to be performed on the patient. A portion of the received anatomical mapping data is selected for AR mapping to an anatomy of the patient. The selected anatomical mapping data is mapped to corresponding anatomical features. An AR environment is displayed to the user, wherein the AR environment includes the mapping of the selected anatomical mapping data to the corresponding anatomical features.

A computer-assisted device includes a first articulated arm and a control unit coupled to the first articulated arm. The first articulated arm is configured to support an end effector. The control unit is configured to determine a virtual coordinate frame, the virtual coordinate frame being of an imaging device for capturing images of a workspace of the end effector, and the virtual coordinate frame being detached from an actual imaging coordinate frame of the imaging device; receive, from an input control configured to be manipulated by a user, a first instrument motion command to move the end effector; and drive the first articulated arm to move the end effector relative to the virtual coordinate frame based on the first instrument motion command.

A system and method for controlling and selecting sources in a room on a network. The system allows a remote viewer to create a virtual presence within the room by providing the available displays, corresponding to the sources, to the remote viewer. The system includes a standardizing technique for improving the communication and overall switching of data for streaming on a network. The system can include a recording server for performing dual recording of the video files in each of a local database and a remote database. A graphical user interface (GUI) display is provided to guide a local user through a medical procedure in the standardized system.
