Application: Endoscopic vessel harvesting with thermal management and augmented reality display (Patent ID: US20240206704A1)
The vessel harvesting system described in the patent by Terumo Corp involves an elongated harvesting instrument that can be inserted into a patient's body to remove a target vessel for use as a bypass. The instrument includes a cutter that applies thermal energy to sever and cauterize side branches of the target vessel. An endoscopic camera captures visible-light images from the instrument's distal tip within a dissected tunnel around the vessel, while a thermal camera captures thermograms to characterize temperatures in the tunnel. An image processor renders a video stream with visible-light images and an overlay showing temperatures on surfaces when thermal energy is applied, with the display presenting this information to the user, potentially through an augmented-reality display.
The system's claims detail various aspects of the vessel harvesting system, including the use of color tints in the overlay to represent different temperature magnitudes, the identification of target vessels and side branches for temperature depiction, and the rendering of cutting indicators to guide the cutter to optimal locations for severing side branches. The image processor can also accumulate heat exposure on the target vessel, display warnings if exposure exceeds a threshold, and provide information on side branch diameter and target energy for severing. Additionally, the display can be in the form of an augmented-reality display worn by the user, enhancing the visualization and guidance capabilities of the system during vessel harvesting procedures.
