    摘要： A fixed blade utility knife has a housing provided by a lower handle portion, an upper lever portion, and a nosepiece at one end thereof which seats one end of the handle and lever. The lever is pivotably supported on the nosepiece, and a blade holder in the nosepiece is pivotably supported on the handle. The blade is seated in the holder and extends outwardly of the nosepiece, and a blade guard of generally U-shaped cross section extends about the cutting edge and is slidable in the nosepiece to extend outwardly to sheathe the cutting edge and to be withdrawn into the nosepiece to expose the cutting edge. A manipulatable element slidably seated in the nosepiece is engaged with the blade guard to effect its sliding movement. Pivoting of the lever into an open position releases the blade from engagement in the holder so that it may be easily replaced.

    摘要： A novel surgical instrument suitable for insertion and assembly of surgical fasteners, such as multi-ring compression devices, for circular anastomosis of tubular or hollow organ tissue sections, including a body having means to support and align the rings, means for clamping the rings around the free ends of the tissue sections, means for coring away excess clamped tissue and the centers of the rings, separate means for releasing the clamped rings from the instrument and dwell means to delay releasing the rings until after the coring operation is complete. The dwell means consists of an external cup containing separate and coaxial elements for the coring means and the releasing means which are provided with a series of recesses and a plurality of shifter keys to separate the operation of coring from the separate operation of releasing the assembled multi-ring compression device from the instrument. The instrument may additionally include means for detaching a portion of the support means to facilitate installation and alignment, a safety to ensure safe operation and various knife blade profiles. Additionally, the surgical instrument may be provided with a longitudinal bore extending throughout the length of the instrument for receipt of accessory instruments therethrough. Further, lockout means may be provided to block the coring means until the rings have been clamped around the tissue sections.

    摘要： A liquid light guide for surgical instrumentation, includes a flexible elongated tube having opposed tube portions, a transmissive member positioned within each tube end portion of the elongated tube to enclose an interior portion of the elongated tube and a light transmissive medium filling the interior portion of the elongated tube. A sealing mechanism forms a fluid tight seal between each tube end portion and the light transmissive plug to prevent leakage of the fluid from the tube. The liquid light guide is capable of providing excellent light transmission over the entire visible spectral range while substantially reducing undesired transmission of infrared and ultraviolet radiation. The light guide is contemplated to be used with an endoscope and is cost-effective to manufacture. Methods of making and using the disposable light guide also are disclosed.

    摘要： A surgical instrument for performing a circular anastomosis is disclosed. The instrument is provided with sealing means to permit use during endoscopic procedures. The first seal is fabricated from polyethylene foam, is disposed about an elongate member and is in at least partial contact with an inner surface of a compression member. The second seal is an O-ring seal configured and dimensioned to at least partially contact an outer portion of the compression member and an inner portion of an outer tube. The second seal is disposed intermediate of the compression member.
