Abstract: A method for guiding a surgeon on how to adapt a pre-planned position of an implant interface. The implant interface is configured to couple to an implant connector configured to connect the implant interface with an implant interface of another implant. The method is performed by a processing system and comprises obtaining a pre-planned position of an implant interface, obtaining reference positions of the implant interface, determining a deviation between the pre-planned position and the reference positions, and triggering display of a visualization comprising an indication of the deviation to guide a surgeon on how to adapt the pre-planned position of the implant interface. A system and a computer program are also described.

Abstract: A technique for automatic spinal cage planning is provided. In particular, a computer-implemented method for automatically planning implementation of one or more spinal cages is provided. The method comprises obtaining image data including a 2D medical image comprising representations of a plurality of vertebrae of a patient's body in a standing body posture and determining a 2D prediction image comprising representations of the plurality of vertebrae of the patient's body in the standing body posture, wherein determining the 2D prediction image comprises modifying the 2D medical image such that at least one spinal balance parameter derivable from the 2D prediction image fulfills a predefined criterion. The method further comprises determining, based on the 2D prediction image, an implementation of one or more spinal cages yielding the poses of the vertebrae as represented by the prediction image.

Abstract: A bone clamp including two or more clamping members configured to clampingly receive a bone therebetween. The bone clamp further includes a basis supporting at least two of the clamping members at a first distance to each other. At least one of the at least two clamping members has a body and is rotatably supported by the basis. The at least one rotatably supported clamping member has a bone engaging structure extending helically along at least a part of a length of its body. The bone engaging structure is configured to engage a side surface of the bone upon rotation of the at least one rotatably supported clamping member. Depending on the direction of the rotation, the rotatably supported clamping member advances along the side surface of the bone either in a downward direction for mounting the bone clamp or in an upward direction for dismounting the bone clamp.

Abstract: A computer-implemented method for supporting a surgeon in validating an implant placement. The method includes obtaining preoperative patient image data including representations of a plurality of anatomical elements of a patient's body. Implant placement data indicative of a pose of at least one placed implant relative to at least one of the anatomical elements is obtained. Tracking data indicative of a change of a relative pose of at least one of the anatomical elements is obtained. Based on the preoperative patient image data, the implant placement data and the tracking data, a first simulated patient image is determined and includes representations of the plurality of anatomical elements with the at least one of the anatomical elements having the changed pose. The simulated patient image includes visualization of the placed implant. Display of the first simulated patient image is triggered to support the surgeon in validating the placement of the implant.

Abstract: Systems and methods for operating a robotic manipulator coupled to an ultrasonic instrument to control movement of the ultrasonic instrument to resect a target volume of patient tissue. The ultrasonic instrument is driven with an AC drive signal that induces vibrations in a tip of the ultrasonic instrument, and is positioned so that a distal region of the tip is vibrating against a portion of the patient tissue. A characteristic of the AC drive signal is obtained when the distal region of the tip is vibrating against the tissue portion, and a determination is made of whether the tissue portion corresponds to the target volume based on the determined characteristic. The robotic manipulator is operated to control movement of the ultrasonic instrument relative to the patient tissue based on the determination.

Abstract: A computer-implemented method for supporting users in an operating room is provided. The method includes obtaining spatial information indicative of a plurality of spatial regions in the operating room, obtaining tracking information indicative of a tracked pose of a medical instrument in the operating room, and obtaining one or more predefined spatial constraints for one or more of the plurality of spatial regions. The method also includes determining whether the one or more predefined spatial constraints are met based on the spatial information and the tracking information, associating the medical instrument with one of the plurality of spatial regions based on whether the one or more predefined spatial constraints are met, and triggering visual feedback according to one or more feedback parameters of the spatial region associated with the medical instrument, wherein the one or more feedback parameters define a perspective of the navigation view.

Abstract: Determining at least one prediction image based on at least one medical image of a patient. A method includes obtaining image data including at least one medical image including representations of a plurality of bones in a first body posture, and alignment data indicative of an alignment of at least two of the bones in a second body posture. At least one prediction image including representations of the bones in the first body posture is determined based on the image data and the alignment data. The medical image(s) may be modified based on the alignment data such that poses of the representations of the bones after the modification comply with the alignment indicated by the alignment data. The at least one prediction image and/or of information derived from one or more of the prediction image(s) may be displayed. A corresponding system, computer program and carrier are also provided.

Abstract: A computer-implemented technique for a user-specific selection of a machine-trained model for determining an implant-related parameter. A set of different machine-trained models is provided. Each model is indicative of a dedicated implant-related parameter for a dedicated patient anatomy. The method may include receiving first patient image data indicative of a patient anatomy in which an implant is to be placed, and applying at least one first model from the set of models on the first patient image data to determine an implant-related parameter. The determined implant-related parameter is suggested to a dedicated user, and feedback is received from the user on the suggested implant-related parameter. The user feedback includes one of a confirmation of the suggested implant-related parameter and an adaptation thereof. At least one second model from the set of models that is to be applied on second patient image data may be selected, based on the user feedback.

The method includes obtaining image data representative of an anatomical element, obtaining implant data indicative of geometrical properties of an implant to be implanted into the anatomical element, and obtaining planning data indicative of a planned pose of the implant.
