A system for creating at least one model of a bone and implanted implant comprises a processing unit; and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for: obtaining at least one image of at least part of a bone and of an implanted implant on the bone, the at least one image being patient specific, obtaining a virtual model of the implanted implant using an identity of the implanted implant, overlaying the virtual model of the implanted implant on the at least one image to determine a relative orientation of the implanted implant relative to the bone in the at least one image, and generating and outputting a current bone and implant model using the at least one image, the virtual model of the implanted implant and the overlaying.

Patient-specific instrumentation for implant revision surgery

A surgical assistance system includes a processing unit; and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for: obtaining a video feed of a surgical procedure and monitoring the surgical procedure from the video feed; detecting, from an image processing of the video feed, a condition requiring a deviation from the surgical procedure, the deviation being defined as being outside of a standard surgical flow; and outputting a recommendation of deviation by intra-operatively providing the recommendation to an operator of the surgical procedure.

Surgery assistance system

A method or system for storing an instrument, such as in a sterile environment. For example, a surgical robotic system may include a surgical robotic arm and a sterilization unit enclosing the sterile environment and storing the instrument. A processor may be used to determine that the instrument is needed (e.g., during a surgical procedure or portion of a surgical procedure or for a future surgical procedure or portion of a future surgical procedure). The processor may provide access to the instrument.

Robotic device and sterilization unit for surgical instrument

A system for sizing an implant for a patient pre-operatively comprises a processor unit. A non-transitory computer-readable memory may be communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for obtaining at least one radiographic patient image of at least one patient bone with a scale marker relative to the bone, the scale marker having a known geometry, setting a scale of the at least one radiographic patient image using the known geometry of the scale marker, generating a three-dimensional bone model representative of the at least one patient bone using the at least one radiographic patient image and the scale, identifying an implant size and/or an implant model using implant models and dimensions of the three-dimensional bone model based on said scale, and outputting the implant size and/or the implant model for the patient.

Method and system for pre-operative implant sizing

Method for reconstruction of a three-dimensional model of an osteo-articular structure of a patient, wherein a) bi-dimensional patient-specific image data () of said structure is provided; (d) a preliminary solution, corresponding to a previously established solution model of the structure, is provided () from a base (), said preliminary solution comprising a priori knowledge of the corresponding structure, previously established from structures of the same type, said preliminary solution comprising surface data describing the coordinates of the surface of the solution model, and bulk data describing at least one characteristic of the inside of the solution model; the preliminary solution is modified () to be brought in concordance with said patient-specific image data.
