摘要： 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.

摘要： A marking/drying tool applies ink to biological tissue using a single handheld device. A cylindrical body retains a felt tip movable between a retracted position within the body and an extended position outside the body for marking the tissue. A gas source has a manual valve to selectably dispensing a drying gas onto the tissue. In a preferred embodiment, an interlock prevents dispensing of drying gas when the tip is in the extended position and prevents the tip moving to the extended position when the manual valve is dispensing the drying gas.

摘要： An endoscopic vessel harvesting system for surgical removal of a blood vessel to be used for coronary bypass uses endoscopic instruments for isolating and severing the vessel. An endoscopic camera in the endoscopic instruments captures images from a distal tip of the instrument within a dissected tunnel around the vessel. An image processor assembles a three-dimensional model of the tunnel from a series of images captured by the endoscopic camera. An augmented-reality display coupled to the image processor renders (e.g., visibly displays to the user in their field of view) a consolidated map representing the three-dimensional model along with a marker in association with the map indicating a current location of the distal tip.

摘要： An endoscopic surgical instrument includes a wiping section that is provided at a tip part of an insertion section and is pivoted to wipe off extraneous matter adhering to an observation surface provided at a tip part of a lens the endoscope through a grip section and the insertion section. An axial member is inserted through the insertion section and is connected to the wiping section. An operation section is provided over a whole circumference of a tip end of the grip section in a longitudinal direction of the grip section, is connected to the axial member, and operates the wiping section through the axial member. A center axis of the operation section is coaxial to a center axis of an endoscope when the endoscope is inserted through the grip section and the insertion section.

摘要： 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.
