    摘要： Components for an endoscopic vessel harvesting system suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The main components of such systems include a vessel dissector and a vessel harvester, both of which work in conjunction with a separately provided endoscope. The vessel dissector is an elongated cannula having a blunt tip for separating layers of facial around vessels. The tip may be movable, and is typically transparent to permit viewing forward of the tip using the endoscope. Internal features of the tip may reduce glare back to the endoscope. Several devices improve visibility through the tip by reducing interference from tissue or fluid on the tip. The vessel harvester also has an elongated cannula for receiving the endoscope. Several tools within the harvester permit manipulation, severing, and sealing of vessels forward of the distal end. The tool for manipulating vessels may have a low-profile for increased visibility of operation, and may be coupled to the cannula with a damping mechanism to reduce the possibility of avulsion of the vessels. Various vessel cutting and sealing devices are provided that may accommodate various sizes of vessels and improve cutting and sealing efficacy.

    摘要： An assembly of cannula and endoscope and dissection tip facilitate surgical procedures at remote surgical site in tissue of a patient. Relative rotation of the cannula about the endoscope from clamped rotational fixation of the cannula and endoscope is made possible by flexing a resilient clamping segment, and such relative rotation promotes convenient positioning of an eccentric tissue-dissecting tip about a vessel being harvested from within tissue of a patient. Color tinting of the tip or color-tinted illumination of tissue at a remote surgical site enhances contrasting visualization through the tip via the endoscope among the tissue types encountered at the surgical site within a patient. A tool bridge or lateral support mounts to a more rigid component such as an endoscope that extends from the proximal end of a cannula to support a more flexible surgical instrument also extending from the proximal end of the cannula.

    摘要： Organ manipulation devices for atraumatically grasping the surface of an organ and repositioning the organ to allow access to a location on the organ that would otherwise be substantially inaccessible. Methods of accessing a beating heart, retracting the heart using an organ manipulation apparatus, and stabilizing a surgical target area with a stabilizer. Both the organ manipulator and stabilizer are fixed to a stationary object which may be a sternal retractor. A system for performing beating heart coronary artery bypass grafting includes a sternal retractor, organ manipulator and stabilizer.
