A method for characterizing a state of an end effector of an ultrasonic device is disclosed. The ultrasonic device including an electromechanical ultrasonic system defined by a predetermined resonant frequency. The electromechanical ultrasonic system further including an ultrasonic transducer coupled to an ultrasonic blade. The method including applying, by an energy source, a power level to the ultrasonic transducer; measuring, by a control circuit coupled to a memory, an impedance value of the ultrasonic transducer; comparing, by the control circuit, the impedance value to a reference impedance value stored in the memory; classifying, by the control circuit, the impedance value based on the comparison; characterizing, by the control circuit, the state of the electromechanical ultrasonic system based on the classification of the impedance value; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the characterization of the state of the end effector.

Methods, systems, and coaptation measurement devices as described herein include an elongate sensor body at the end of a proximal connecting member, and a plurality of sensors in an array across a face of the sensor body, wherein each sensor of the plurality of sensors is configured to detect if a portion of a heart valve is in contact with the sensor.

A method of detecting colon polyps disclosed in the present disclosure includes: (a) receiving an image captured by an endoscope inserted into colon of a test subject; (b) recognizing each image section including colonic mucosa and colonic blood vessels in the image; (c) determining whether a colonic vascular bed is disconnected in each image section; (d) displaying a first visual effect representing a vascular bed in which the colonic blood vessels are disconnected; and (e) displaying a second visual effect representing a continuous vascular bed of the colonic blood vessels, wherein operation (b) is configured to recognize each image section through a deep learning model, which is machine learned based on blood vessel data in a plurality of colonic images of the test subject obtained from external annotators, and a degree of disconnection of the vascular bed and a blood vessel pattern.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

A deflectable endoscope including an imaging structure, an outer member having a proximal portion and a distal portion, an elongated column member extending distally from the outer member and an inner member positioned coaxial with the outer member and attached to the column member. The inner member extends distally of the outer member and has a distal tip portion. A reinforcement member is positioned over the column member to restrict axial movement of the column member such that when one of the inner member or outer member is moved with respect to the other, axial compression of the column member is restricted by the reinforcement member causing the distal tip portion of the inner member to deflect laterally.

Various surgical systems are disclosed. A surgical system can include a surgical robot and a surgical hub. The surgical robot can include a control unit in signal communication with a control console and a robotic tool. The surgical hub can include a display. The surgical hub can be in signal communication with the control unit. A facility can include a plurality of surgical hubs that communicate data from the surgical robots to a primary server. To alleviate bandwidth competition among the surgical hubs, the surgical hubs can include prioritization protocols for collecting, storing, and/or communicating data to the primary server.

A system and method for video assisted percutaneous needle cricothyrotomy and tracheostomy to assist physicians in quickly intubating patients suffering from respiratory distress when oral or nasal intubation is not possible or contraindicated. The system and method includes a display monitor, a percutaneous needle assembly including a connection hub having a syringe port for removably attaching a syringe, a needle port for attaching a hollow needle, and a stylet port in communication with the needle port for receiving a fiber optic stylet that extends through the hollow needle. The fiber optic stylet includes one or more illuminators, and a camera for capturing and transmitting anatomical images for display on the display monitor to visually assist physicians in locating a patient's trachea lumen. The fiber optic stylet is positioned within the trachea lumen, and used as a guide wire to insert a dilator and cannula for ventilating the patient.

A system for controlling a medical image capture device during surgery, the system including: circuitry configured to receive a first image of the surgical scene, captured by the medical image capture device from a first viewpoint, and additional information of the scene; determine, for the medical image capture device, in accordance with the additional information and previous viewpoint information of surgical scenes, one or more candidate viewpoints from which to obtain an image of the surgical scene; provide, in accordance with the first image of the surgical scene, for each of the one or more candidate viewpoints, a simulated image of the surgical scene from the candidate viewpoint; control the medical image capture device to obtain an image of the surgical scene from the candidate viewpoint corresponding to a selection of one of the one or more simulated images of the surgical scene.

An image of a field of view is captured by the endoscope and a portion of the image is displayed on a display. A popup image is generated and displayed upon image analysis identification of an occurrence of bleeding or motion of edges of an incision that is within the field of view, but outside the portion of the field of view displayed on the display.

The present disclosure is directed towards a video display system and an endoscopic system configured to provide the surgeon with an optimized video image based upon user preference. The video display system includes a first video image displaying a white light video of a surgical site. The first video image has a first predetermined area. A second video image is overlaid on the first video image. The second video image is displayed in a fluorescent light video. The second video image is centered on the surgical site and includes a second predetermined area. The second predetermined area is smaller than the first predetermined area so as to define a boundary of white light video. Thus, the video display system provides the surgeon with the ability to reference the location of the fluorescent light video with respect to anatomical features of the surgical site.
