Publication number: 20200305975Abstract: A device includes a catheter section comprising a flexible joint region disposed between a distal end and a proximal end. The device includes a laser fiber disposed within the catheter section. The laser fiber emits laser light at a fiber distal end. The device includes a wire comprising a distal end coupled to the catheter section. The wire is configured to move the distal end of the catheter section from a first position to a second position about the flexible joint region.Type: ApplicationFiled: October 31, 2019Publication date: October 1, 2020Inventors: Samuel H. SHUFFLER, Mark G. FONTENOT

Publication number: 20200305976Abstract: The invention relates to a method of determining the sagittal rotation of a patient's pelvis based on a standard anterior posterior X-ray-image with known image parameters and a calibration of the image, for example by using at least one King-Mark calibration object. The angle of the pelvic rotation is determined between a pelvic plane which is orthogonal to the midsagittal plane of the pelvis, and the image plane of the X-ray-image. Assuming the patient's position shown on the X-ray-image represents a standard neutral position, the X-ray-image plane can be used as a functional reference plane for further calculations, for example during hip-replacement surgery. The present invention further relates to a corresponding computer program and system.Type: ApplicationFiled: March 1, 2018Publication date: October 1, 2020Inventors: Steffen BECK, Mario SCHUBERT, Christian BRACK, Luise POITZSCH

Publication number: 20200305977Abstract: A guided frame matching technique may be employed in which a graphical projection of a fixator is used to guide and assist a user in identifying fixator elements within an image. Upon being overlaid on an image, the graphical projection of fixator may be manipulated to align with, and overlay, fixator elements displayed within the image. Additionally, a three-dimensional overview of an imaging scene of the fixator may be generated. The three-dimensional overview may include a three-dimensional graphical model that displays representations of images of the fixator attached to anatomical structure segments as well as representations of imaging sources, reference locations, fixator elements, and anatomical structure segments. When the images are not truly orthogonal, a modified second image representation may be displayed to represent a second image that is truly orthogonal to a first image.Type: ApplicationFiled: March 28, 2019Publication date: October 1, 2020Inventors: Bernd Gutmann, Martin Raabe

Publication number: 20200305978Abstract: A computer-implemented method to improve the point collection process during registration of a bone for a computer-assisted surgical procedure is provided. Based on bone digitization data, a simulation is performed to confirm the accuracy of the registration for different digitization regions. Results are tested to identify which digitization regions meet a predefined accuracy requirement. The resulting information is used to perform a computer-assisted surgical procedure. A computerized simulation method for registration of a bone for a computer-assisted surgical procedure is also provided based on processor executing random stroking an expected exposed surface of a bone model with multiple of stroke curves to cover most of the bone model surface with uniform noise and a random sample consensus is applied to remove outlying point to yield the best registration results, to find the top subset as to overlap. A method to perform computer-assisted surgery is also provided.Type: ApplicationFiled: March 31, 2020Publication date: October 1, 2020Applicant: THINK SURGICAL, INC.Inventors: Yiyong Tan, Randall Hanson, Aruna Gummalla

Publication number: 20200305979Abstract: A surgical implant planning computer is connectable to a fluoroscopy imager, a marker tracking camera, and a robot having a robot base coupled to a robot arm that is movable by motors relative to the robot base. Operations include performing a registration setup mode that determines occurrence of a first condition indicating the marker tracking camera can observe to track reflective markers that are on a fluoroscopy registration fixture of the fluoroscopy imager, and determines occurrence of a second condition indicating the marker tracking camera can observe to track dynamic reference base markers attached to the robot arm and/or an end-effector connected to the robot arm. While both of the first and second conditions occur, operations are allowed to be performed to obtain a first intra-operative fluoroscopic image of a patient along a first plane and to obtain a second intra-operative fluoroscopic image of the patient along a second plane that is orthogonal to the first plane.Type: ApplicationFiled: April 17, 2020Publication date: October 1, 2020Inventors: Neil R.
