    摘要: A trocar for placement in the lumen of a cannula to facilitate inserting the cannula through the wall of a body cavity, the trocar comprising an obturator with a point for piercing the wall of the body cavity, and a protective sleeve mounted concentrically around the obturator. The obturator retracts proximally relative to the protective sleeve after the trocar point has penetrated through the wall of the body cavity. The protective sleeve is mounted for axial movement relative to the obturator, retracting proximally in response to drag from the wall of the body cavity as the trocar is advanced through the wall, and advancing distally after the cannula has penetrated through the wall, reducing the drag on the sleeve. The distal advancement of the sleeve triggers the retraction of the obturator.

    摘要: A surgical stapler for use by a surgeon to place one or more rows of surgical staples in organs or tissue. The stapler is of a character having a supporting frame, a replaceable staple cartridge, an anvil, a mechanism for approximating the cartridge relative to the anvil, and a mechanism for firing the device so as to crimp the staples against the anvil. The device, while at all times permitting approximation of the cartridge relative to the anvil, provides a novel safety mechanism that clearly indicates to the surgeon that the staples have been fired from the staple cartridge and simultaneously disables the device until it is manually reset.

    摘要: A medical backcheck valve includes a hollow housing containing an upwardly biased piston assembly for controlling liquid flow therethrough. The piston assembly comprises a substantially rigid plug having one end protruding from the upper end of the housing, and a flexible sheath covering having a relatively small diameter upper end surrounding the plug, a main seal for controlling flow through said first flow space, and a tubular lower end, secured at the bottom of the housing, for preventing liquid from entering within the covering.

    摘要: An improved stapler firing assembly and a surgical stapler are disclosed. The stapler comprises structural members having handle parts with opposite sides and jaw parts projecting from the handle parts. The stapler includes a mechanism for releasable engagement between an elongate locking member and the structural members comprising a lever lock including a hook portion adapted to pass through a slot in a handle part. The lever lock is mounted on the locking member and includes first and second release buttons and actuating means mounting the first and second release buttons on opposite sides of the locking member for movement between first and second positions with respect to the locking member. The stapler firing assembly comprises a pusher adapted to move longitudinally along one of the jaw parts to sequentially press the staples against an anvil. There is also present a firing handle body having opposite end portions and a mechanism mounting the handle body on the pusher for movement relative to the pusher between a first position and a second position so that the firing handle body can be positioned to be manually engaged on either side of the handle parts to move the second end of the pusher along the second jaw to eject and close the staples.

    摘要: A surgical instrument with articulated jaw structure includes a frame and two jaws. The jaws have proximal portions that are mounted to each other for movement in a substantially parallel relation between a fully open position wherein the jaws are separated for receiving tissue therebetween and an approximated position wherein the jaws are closer together. Preferably, the jaws are in the fully open position when the distal portion of at least of the jaws is located in an extended position and are in the approximated position when the distal portion of the extended jaw or jaws is located in a retracted position. The surgical instrument may further include a detachable knife assembly and knife actuating mechanism.
