Patent number: 11793526Abstract: An embodiment in accordance with the present invention provides a continuum dexterous manipulator (CDM) with a specially designed flexible tool, to be used as a handheld or robotic steerable device for treatment of hard-tissue-related diseases. The CDM of the present invention works well in treatment of soft and sticky material (similar to a lesion) as well as milling the hard tissues (e.g. sclerotic liner of osteolytic lesions) and bone tumors. The present invention is also directed to flexible drilling tools as well as characterization and evaluation of integrating these tools with the CDM in curved-drilling of hard bone towards treatment of hard tissue related diseases (e.g. osteonecrosis or pelvic fracture). The present invention can also include use of various types of drill geometries, aspiration and irrigation, and endoscope view in curved-drilling and trajectory planning.Type: GrantFiled: January 3, 2018Date of Patent: October 24, 2023Assignee: The Johns Hopkins UniversityInventors: Farshid Alambeigi, Mehran Armand

Publication number: 20220296193Abstract: A method of representing a relative change in position and/or orientation of a bone portion during a surgical procedure according to some embodiments of the invention includes receiving preoperative x-ray computed tomography (CT) images of a bone that will have a portion separated and moved during the surgical procedure. Multiple x-ray images are received, each a different view of the bone during the surgical procedure prior to separating and moving the portion, where the bone has a fiducial marker fixed relative to that portion and another fiducial marker fixed relative to a stationary portion of the bone. The fiducial markers each have at least three radio-opaque points and remain substantially fixed with respect to each other. The position of the radio-opaque points is determined relative to a three-dimensional representation of the bone from the preoperative CT images. After separating and moving the portion, a single x-ray image is received that includes both fiducial markers.Type: ApplicationFiled: September 4, 2020Publication date: September 22, 2022Applicant: The Johns Hopkins UniersityInventors: Robert Grupp, Russell H. Taylore, Mehran Armand

Patent number: 11364629Abstract: A flexible manipulator apparatus includes an elongate flexible manipulator having a sensor, a user output device configured to provide sensory outputs to the user, and processing circuitry. The flexible manipulator may be movable to form a curve in the flexible manipulator. The processing circuitry may be configured to receive captured sensor data from the sensor during movement of the flexible manipulator, and determine a collision likelihood score based on application of the captured sensor data to a collision detection model used for position estimation. The collision detection model may be based on an empirical data training for the flexible manipulator that includes training sensor data from the sensor and training image data of positions of the flexible manipulator. The processing circuitry may be configured to control the user output device based on the collision likelihood score to provide a collision alert sensory output to the user.Type: GrantFiled: February 26, 2020Date of Patent: June 21, 2022Assignee: The Johns Hopkins UniversityInventors: Shahriar Sefati, Mehran Armand, Iulian Iordachita
