Publication number: 20190201100Abstract: A method of reducing retro-repulsion of a kidney stone during a laser lithotripsy procedure utilizes a protective cap or sleeve fitted onto an end of the laser delivery fiber and extending a predetermined distance beyond a tip of the fiber to prevent contact between the tip of the fiber and a stone to limit retro-repulsion by maintaining contact between the protective cap and the stone, thereby limiting the amount of water in the path of the laser between the fiber tip and the stone. The method may further include the step of firing the laser only when contact between the protective cap and the stone is detected, implemented manually or by a contact detection system. The fiber tip may be outwardly tapered to collimate the laser beam and allow an increased spacing between the fiber tip and the distal end of the protective cap.Type: ApplicationFiled: December 28, 2018Publication date: July 4, 2019Inventors: JOE D.

Publication number: 20190201101Abstract: This invention relates to Patient-Specific Templates (PST) which have already been used by implant manufacturers and clinically applied by orthopedic surgeons. This work presents an apparatus comprised of a unit acquiring data from the surface of bones and joints, a computerized unit for surgical planning and a desktop 3D printer for manufacturing PST, which are functionally, physically and electrically connected. The apparatus is compact, portable and suitable for hospital-based or clinic-based service. The data-collection unit has electro-magnetic (EM) device, diagnostic ultrasound machine, laser scanner and a receiver for acquisition of external data. It integrates the data from multiple sources and has sensor fusion ability. The surgical planning unit has specific software program capable of merging the collected data through mathematical model of specific parts of bones, joints and a library of implants and prostheses.Type: ApplicationFiled: April 26, 2016Publication date: July 4, 2019Inventor: Mahmoud Alm El Din Hafez

Publication number: 20190201102Abstract: Various systems and methods providing recommendations based on analysis of surgical procedure variables are disclosed. A computer system, such as a surgical hub, can be configured to be communicably coupled to a surgical device. The computer system can be programmed to determine contextual data related to the surgical procedure being performed based at least in part of perioperative data received from the surgical device paired with the computer system. Further, the computer system can determine a procedural variable associated with the determined surgical context and then compare the procedural variable to a baseline. Depending upon the outcome of the comparison, the computer system can provide intraoperative or postoperative recommendations to the surgical staff.Type: ApplicationFiled: November 6, 2018Publication date: July 4, 2019Inventors: Frederick E. Shelton, IV, Jason L. Harris, Taylor W. Aronhalt

Publication number: 20190201103Abstract: An apparatus includes a memory and a processor. The memory is configured to hold values indicative of known relative positions of multiple position sensors of a position tracking system that are coupled to a medical device. The processor is configured to receive one or more signals indicative of estimated positions of the position sensors, as measured by the position tracking system, and to initiate a responsive action in response to detecting a discrepancy between the known relative positions and the estimated positions.Type: ApplicationFiled: January 2, 2018Publication date: July 4, 2019Inventor: Assaf Govari

Publication number: 20190201106Abstract: A computer-implemented system with at least one processor that reads a set of 2D slices of an intraoperative 3D volume, each of the 2D slices comprising an image of an anatomical structure and of a registration grid containing an array of markers; detects the markers of the registration grid on each of the 2D slices by using a marker detection convolutional neural network (CNN); filters the marker detection results for the 2D slices to remove false positives by processing the whole set of the 2D slices of the intraoperative 3D volume; and determines the 3D location and 3D orientation of the registration grid with respect to the intraoperative 3D volume, by finding a homogeneous transformation between the filtered marker detection results for the intraoperative 3D volume and a reference 3D volume of the registration grid.Type: ApplicationFiled: December 31, 2018Publication date: July 4, 2019Inventors: Kris B.

Publication number: 20190201107Abstract: A robotic surgical system includes an eye gaze sensing system in conjunction with a visual display of a camera image from a surgical work site. Detected gaze of a surgeon towards the display is used as input to the system. This input may be used by the system to assign an instrument to a control input device (when the user is prompted to look at the instrument), or it may be used as input to a computer vision algorithm to aid in object differentiation and seeding information, facilitating identification/differentiation of instruments, anatomical features or regions.Type: ApplicationFiled: December 31, 2018Publication date: July 4, 2019Inventor: Kevin Andrew Hufford
