    摘要： A trocar assembly consisting of a trocar tube subassembly and a separable, interfitting trocar subassembly is described. The trocar tube assembly includes a hollow body having a first front opening in which a trocar tube is mounted, a second rear opening for receiving the trocar subassembly, and a manually pivotable flap valve mechanism mounted within the body. The trocar subassembly includes a head having a central bore in which are mounted the (1) rear ends of an elongated obturator having a pyramidal-shaped piercing head with a triangular-shaped base, and a concentric tubular shield having a triangular shaped front opening for the piercing head that is formed by bevels in its leading edge that have approximately the same slope as the surfaces that define the three sides of the piercing head, and (2) a coil spring backing the shield for biasing the shield between retracted and extended positions. When the two subassemblies are fit together, the obturator and concentric shield extend through the hollow body with the front wall of the head fitting within a recess in the rear wall of the hollow body such that the trocar assembly cannot be rotated without disengaging the two subassemblies. The shield has a slot in its outer wall that is engaged by the flap valve to lock the shield in its extended position. The shield may be unlocked by pivoting the flap valve out of the slot, sliding the trocar assembly rearwardly so that the front wall of the head is clear of the recess in the rear wall of the hollow body, rotating the trocar subassembly to a position in which the flap valve and slot are not aligned and sliding the front wall of the trocar assembly back into the recess in the rear wall of the hollow body.

    摘要： A trocar assembly consisting of a trocar tube subassembly and a separate interengageable trocar body subassembly is provided. The trocar body subassembly includes an elongated obturator having a sharp pointed tip which is normally housed within an elongated tube of the trocar tube subassembly. The obturator is extendable from a retracted position within the tube wherein the tip is recessed from the tube end to an operative position forward of said tube end and outside the tube. By manually advancing the trocar assembly against a body wall, the resisting force locks the obturator in the operative position. Relaxation of the force incident to passing through the body wall causes the obturator to be automatically unlocked and retracted to its initial position with the tip positioned protectively within the tube, thereby protecting body tissues and organs from being damaged by the tip when it enters a body cavity beyond the wall.

    摘要： A system for performing an end-to-side vascular anastomosis, including an anastomosis device, an application instrument and methods for performing a vascular anastomosis. The system is applicable for performing an anastomosis between a vascular graft and the ascending aorta in coronary artery bypass surgery, particularly in port-access CABG surgery. A first aspect of the invention includes a vascular anastomosis staple. A first configuration has two parts: an anchor member, forming the attachment with the target vessel wall and a coupling member, forming the attachment with the bypass graft vessel. The anastomosis is completed by inserting the coupling member, with the graft vessel attached, into the anchor member. A second configuration combines the functions of the anchor member and the coupling member into a one-piece anastomosis staple. A second aspect of the invention includes an anastomotic fitting, having an inner flange over which the graft vessel is everted and an outer flange which contacts the exterior surface of the target vessel. A tailored amount of compression applied by the inner and outer flanges grips the target vessel wall and creates a leak-proof seal between the graft vessel and the target vessel. A third aspect of the invention has a flange to which the graft vessel attaches, by everting the graft vessel over the flange, and a plurality of staple-like members which attach the flange and the everted end of the graft vessel to the wall of the target vessel to form the anastomosis.
