    摘要: A steerable, tendon-driven endoscope is described herein. The endoscope has an elongated body with a manually or selectively steerable distal portion and an automatically controlled, segmented proximal portion. The steerable distal portion and the segment of the controllable portion are actuated by at least two tendons. As the endoscope is advanced, the user maneuvers the distal portion, and a motion controller actuates tendons in the segmented proximal portion so that the proximal portion assumes the selected curve of the selectively steerable distal portion. By this method the selected curves are propagated along the endoscope body so that the endoscope largely conforms to the pathway selected. When the endoscope is withdrawn proximally, the selected curves can propagate distally along the endoscope body. This allows the endoscope to negotiate tortuous curves along a desired path through or around and between organs within the body.

    摘要: The invention provides a system and method for performing less-invasive surgical procedures within a body cavity. In a preferred embodiment, the invention provides a system and method for isolating a surgical site such as an anastomosis between an internal mammary artery and a coronary artery in a thoracoscopic coronary artery bypass grafting procedure. The system comprises a foot (11) pivotally coupled to the distal end of a shaft (3) by a linkage (13). The foot has first and second engaging portions (15, 17) with contact surfaces for engaging a tissue surface. The engaging portions are movable between an open position, where the contact surfaces are separated by a gap, and a collapsed position, where the foot is configured for delivery through the percutaneous penetration. An actuator, at the proximal end of the shaft, can be rotated to pivot the foot about a transverse axis so that the contact surfaces are oriented generally parallel to the surgical site to apply pressure to the tissue structure on both sides of the surgical site.

    摘要: The invention provides devices and method for performing extremely small-scale, minimally-invasive microsurgery such as thoracoscopic coronary artery bypass grafting. The instruments of the invention utilize a symmetrical, forcep-like actuator which provides extremely precise actuation and control of the instrument and which mimics the feel of instruments used in conventional open surgical procedures. The instruments generally include a pair of coaxially arranged shafts, an end-effect at the distal ends of the shafts, and an actuator at the proximal ends of the shafts. The actuator includes a pair of arms pivotally coupled to one of either the outer or inner shaft, and a pair of links pivotally coupled at one end to the arms, and at a second end to the other of the shafts. The links are coupled to a proximal portion of the arms to maximize mechanical advantage and reduce interference. The actuator may be easily adapted for either pull-type or push-type actuation, and for either outer shaft or inner shaft translation. The end-effectors may have a variety of configurations, including needle drivers, forceps, scissors, and clip appliers.
