摘要： Methods and systems of placing a medical fastener at a predetermined depth in a bone are described. A surgical tool can include an attachment assembly configured to interchangeably engage a medical fastener and a cutting element or bone removal tool and a drive assembly coupled to the attachment assembly. The attachment assembly can be configured to automatically release the medical fastener in response to the drive assembly reaching its end or distal-most position to place the medical fastener at a predetermined depth within the bone.

摘要： Systems and methods for controlling the placement and movement of a robotic arm of a robotic surgical system are provided. A surgical computer system can be configured to determine a recommended position for the robotic arm based on the calculated workspace volume for the robotic arm and the location of the surgical site. A surgical computer system can also be configured to control the robotic arm according to whether it is located within a surgical workspace defined by the surgeon or with respect to the surgical site.

摘要： A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

摘要： A computer-implemented method of improving a patello-femoral response is described. A computing system characterizes an anterior geometry of a patella and determines a position of a posterior apex of the patella in relation to one or more features of the anterior geometry of the patella. The computing system further receives location information related to the patella as a knee joint is moved through a range of motion. The computing system provides one or more recommendations to improve a patello-femoral response.

摘要： The present disclosure provides a machine learning model to model a normal version of a bone from an abnormal version of the bone. The machine learning model can be trained with a training set including abnormal bone images and corresponding normalized, or post-operative, bone images. The abnormal bone image and the inferred normal bone image can be used to plan a surgery to correct the abnormal bone with a surgical navigation system.

摘要： Optical tracking of objects in arthroscopic surgery. Examples comprise a resection instrument system including: a handpiece; a mechanical resection device comprising a stationary outer hub, an elongate outer tube coupled to and extending away from the stationary outer hub, and a cutter disposed at a distal end of the elongate shaft, the stationary outer hub coupled to the handpiece; a fiducial array; and a sleeve connector. The sleeve connector may include: a sleeve defining a distal end, a proximal end, and a through bore, the sleeve concentrically arranged with the elongate shaft; an array connector coupled to the proximal end of the sleeve, the array connector coupled to the fiducial array.

摘要： Devices, systems, and computer-implemented and surgical methods for providing and/or using optical, visual, and/or audio feedback when using a surgical instrument, such as to position and orient an implant are disclosed. A device includes a frame and a C-ring. The frame includes a fixation component optionally located at a first end and a tracking array optionally located at an opposing second end. The fixation component can be positioned at or near a center axis of the C-ring and is configured to releasably engage a surgical instrument. The tracking array may include tracking elements, such as reflective surfaces. The C-ring may include a plurality of light sources optionally arranged in a radial pattern. The light sources may be selectively illuminated based on a determined realignment to provide optical feedback with respect to at least a direction in which the surgical instrument should be moved to achieve a planned alignment.

摘要： A system for tracking resection planes during a surgical procedure includes a cutting block and a position tracker. The cutting block is configured to be mounted on an anterior surface of a bone during the surgical procedure. The cutting block comprises at least one slot configured to position a resection tool during the surgical procedure. The position tracker is configured to be directly attached to the cutting block after the cutting block is mounted on the anterior surface to allow positional tracking of the cutting block by a tracking device during the surgical procedure.

摘要： A method for optimizing a knee arthroplasty surgical procedure includes receiving pre-operative data comprising (i) anatomical measurements of the patient, (ii) soft tissue measurements of the patient's anatomy, and (iii) implant parameters identifying an implant to be used in the knee arthroplasty surgical procedure. An equation set is selected from a plurality of pre-generated equation sets based on the pre-operative data. During the knee arthroplasty surgical procedure, patient-specific kinetic and kinematic response values are generated and displayed using an optimization process. The optimization process includes collecting intraoperative data from one or more surgical tools of a computer-assisted surgical system, and using the intraoperative data and the pre-operative data to solve the equation set, thereby yielding the patient-specific kinetic and kinematic response values. A visualization is then provided of the patient-specific kinetic and kinematic response values on the displays.

摘要： An ultrasound probe captures real-time images of patient anatomy, which are analyzed by a processor to extract salient features pertaining to an anatomical structure. By tracking the location and orientation of the ultrasound probe, a model of that anatomical structure can be created. A visual indication of the position of segments of the anatomical structure can be presented holographically to a user of an augmented reality headset to provide information extracted from the ultrasound imaging, such as holographic display of a model of the anatomical structure at the approximate location of the visual field of the headset corresponding to the physical location of the actual anatomy being viewed by a user, without presenting the entirety of the ultrasound image to the user.
