  • Publication number: 20190350618
    Abstract: A surgical obturator comprising an elongate shaft extending along an axis between a proximal end and a distal end includes a bladeless tip disposed at the distal end of the shaft. The tip has a blunt point and a pair of shorter side surfaces separated by a relatively longer pair of opposing surfaces to form in radial cross-section a geometric shape that has a longer length and relatively narrower width. The side surfaces and opposing surfaces terminate in end surfaces located proximally from the blunt point. The end surfaces extend radially outwardly from opposite locations of the outer surface. A conical surface facilitates initial insertion of the obturator and the geometric shape facilitates separation of consecutive layers of muscle tissue having fibers oriented in different directions and provides proper alignment of the tip between the layers of muscle.

  • Publication number: 20190350622
    Abstract: A device for facilitating a total laparoscopic hysterectomy includes a cervical cup adapted to abut the cervicovaginal junction. An electrocautery wire has an uninsulated portion housed in the cervical cup which includes a channel for housing and controlled releasing the uninsulated portion. An introducer is coupled to the electrocautery wire and configured to penetrate the cervicovaginal junction thereby introducing the electrocautery wire into the intra-abdominal cavity. A shaft secures the electrocautery wire and pulling the electrocautery wire causes a controlled release of the uninsulated portion along a predetermined circumferential path around the cervix along the channel. Thus, the vagina is severed from the cervix along the circumference of the cervicovaginal junction.

The model implant is positioned on the model bone in a desired implant position. A first boundary volume of a first fastener configured to fasten the prosthesis to the bone is also displayed on the display device. The first boundary volume represents a range of possible positions that the first fastener may have with respect to the prosthesis when fastened to the bone. The boundary volume may be used to determine a desired size, shape, and/or positioning of the fastener with respect to the bone.

  • Publication number: 20190350658
    Abstract: Systems and methods are provided for performing intraoperative fusion of two or more volumetric image datasets via surface-based image registration. The volumetric image datasets are separately registered with intraoperatively acquired surface data, thereby fusing the two volumetric image datasets into a common frame of reference while avoiding the need for complex and time-consuming preoperative volumetric-to-volumetric image registration and fusion. The resulting fused image data may be processed to generate one or more images for use during surgical navigation.

  • Publication number: 20190350659
    Abstract: Medical imaging systems and methods are provided herein that provide for navigation and procedure planning without segmentation. A method comprises receiving, by a medical imaging system having at least one processing device, three-dimensional image data of a patient anatomy. The method also comprises filtering the three-dimensional data to display a portion of the three-dimensional image data that is associated with the patient anatomy and receiving, at the processing device, input from an operator input device. The input comprises navigational directions for virtual movement within a space defined by the three-dimensional image data. The method also includes tracking the virtual movement and generating a first model of the patient anatomy based on the tracked virtual movement.
