In a method and system for providing visual information about a tumour location in human or animal body, an electromagnetic tumour sensor is provided in the tumour and tracked to determine its location in space, which is mapped to a tumour model. A surgical tool sensor is provided on a surgical tool, and tracked to determine its location in space, which is mapped to a surgical tool model. The body is scanned to obtain information about an anatomical structure. A reference sensor is provided on the body, and tracked to determine its location in space, which is mapped to the anatomical structure. A virtual image is displayed showing the tumour model, located with the at least one tumour sensor, in spatial relationship to the surgical tool model, located with the at least one surgical tool sensor, and the anatomical structure, located with the at least one reference sensor.

An imaging system aka 3d camera operative in conjunction with a tube having two open ends, the system comprising active portions small enough to fit into the tube and an electronic subsystem including a hardware processor operative to receive image/s from the active portions and to generate therefrom at least one 3D image of a scene visible via one of the tube's open ends. The system may comprise a tracker configured to be secured to the tube, and a method for monitoring location, e.g. absolute location, of the tube, accordingly.

It is judged that a relevant tool is lost at a second time point after the elapse of a certain amount of time or longer after a first time point when it is judged that the tool is not recognized at all in images; and regarding the tool which is judged to have been lost, trace data corresponding to heads-up time, which is immediately before the first time point to immediately after the first time point, is read with reference to a corresponding identifier and a movement locus of the tool based on the trace data is displayed on a screen.

A system and device (110) for determining bone laxity. For example, the system includes a tracked probe (300) comprising at least one probe marker (310) and a computer assisted surgical (CAS) system (100). The CAS system includes a navigation system (130) and a processing device (110) operably connected to the navigation system and a computer readable medium configured to store one or more instructions that, when executed, cause the processing device to receive location information from the navigation system, generate (820) a surgical plan comprising a post-operative laxity assumption (720), collect (850) first motion information related to movement of the joint through a first range of motion, collect (860) second motion information related to movement of the joint through a second range of motion, determine (870) a post-operative laxity (710), and compare the post-operative laxity and the post-operative laxity assumption to determine laxity results.

Systems and methods track objects within an operating room. A machine vision system includes a camera and a controller. A navigation system includes a camera unit including a sensor array. The sensor array includes a plurality of sensing elements. The controller system identifies a first subset of the plurality of sensing elements to be active based on the position of the object. The controller is also configured to track a movement of the object within the operating room using the first subset of the plurality of sensing elements while preventing the use of the second subset of the plurality of sensing elements.

Disclosed herein are a surgical system for patella tracking and a method for selecting a properly-sized patellar implant utilizing the same. The surgical system may include first and second trackers and a patellar tracking system. The first tracker may be configured to contact an unresected or a resected patella, and the second tracker may be configured to contact a bone. The patellar tracking system may be configured to track the first and second trackers during patellar flexion and extension to generate patellar range of motion and patellar trial range of motion. A method for selecting a patellar implant may utilize the first and second trackers and the patellar tracking system.

A passive end effector of a surgical system includes a base connected to a rotational disk, and a saw attachment connected to the rotational disk. The base is attached to an end effector coupler of a robot arm positioned by a surgical robot, and includes a base arm extending away from the end effector coupler. The rotational disk is rotatably connected to the base arm and rotates about a first location on the rotational disk relative to the base arm. The saw attachment is rotatably connected to the rotational disk and rotates about a second location on the rotational disk. The first location on the rotational disk is spaced apart from the second location on the rotational disk. The saw attachment is configured to connect to a surgical saw including a saw blade configured to oscillate for cutting. The saw attachment rotates about the rotational disk and the rotational disk rotates about the base arm to constrain cutting of the saw blade to a range of movement along arcuate paths within a cutting plane.

A surgical system includes an XR headset and an XR headset controller. The XR headset is configured to be worn by a user during a surgical procedure and includes a see-through display screen configured to display an XR image for viewing by the user. The XR headset controller is configured to receive a plurality of two-dimensional (“2D”) image data associated with an anatomical structure of a patient. The XR headset controller is further configured to generate a first 2D image from the plurality of 2D image data based on a pose of the XR headset. The XR headset controller is further configured to generate a second 2D image from the plurality of 2D image data based on the pose of the XR headset. The XR headset controller is further configured to generate the XR image by displaying the first 2D image in a field of view of a first eye of the user and displaying the second 2D image in a field of view of a second eye of the user.
