A vessel harvesting system removes a target vessel from a patient for use as a bypass. An elongated harvesting instrument inserts into a body along a path of a target vessel which includes at least one side branch. The harvesting instrument includes a cutter for applying thermal energy to sever and cauterize the side branch. An endoscopic camera captures visible-light images from a distal tip of the instrument within a dissected tunnel around the target vessel. A thermal camera captures thermograms coinciding with the visible-light images to characterize a temperature present at respective surfaces in the tunnel. An image processor (e.g., an electronic controller) renders a video stream including the visible-light images and an overlay depicting the temperatures present on at least some of the respective surfaces when applying the thermal energy. A display presenting the video stream and overlay to a user can be an augmented-reality display.

A surgical instrument includes a motor-driven drive shaft, a distal firing rod coupled to a driven element of a surgical end effector, and a clutch mechanism coupled between the drive shaft and the distal firing rod. The clutch mechanism is configured to electrically connect the drive shaft and the distal firing rod upon the distal firing rod experiencing a threshold force. The electrical connection signals a processor that the threshold force has been exceeded.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

A torque detection vascular therapy system employing a vascular therapy device (101) and a torque detection controller (130). The vascular therapy device (101) is operable to be transitioned from a pre-deployed state to a post-deployed state, and includes a matrix of imageable markers representative of a geometry of the vascular therapy device (101). The torque detection controller (130) controls a detection of a non-torsional deployment or a torsional deployment of the vascular therapy device (101) subsequent to a transition of the vascular therapy device (101) from the pre-deployed state to the post-deployed state by deriving a vector indication of the non-torsional deployment or the torsional deployment of the vascular therapy device (101) from a matrix orientation similarity or a matrix orientation dissimilarity between a baseline device geometry of the vascular therapy device (101) represented by the matrix of the imageable markers and an imaged device geometry of the vascular therapy device (101) represented by the matrix of imageable markers.

A robotic surgical system and method are disclosed for transitioning control to a secondary robotic arm controller. In one embodiment, a robotic surgical system comprises a user console comprising a display device and a user input device; a robotic arm configured to be coupled to an operating table; a primary robotic arm controller configured to move the robotic arm in response to a signal received from the user input device at the user console; and a secondary robotic arm controller configured to move the robotic arm in response to a signal received from a user input device remote from the user console. Control over movement of the robotic arm is transitioned from the primary robotic arm controller to the secondary robotic arm controller in response to a failure in the primary robotic arm controller. Other embodiments are provided.
