    摘要: An improved clip or clamp is provided having a one-piece wire-form construction that is suited for rapid and repeatable manufacture. The clamp, which may be disposable or reusable, includes a first jaw portion, a second jaw portion, a first handle portion, a second handle portion and a central coil or tensioning device, all of which are formed from a single piece of wire. The central coil or tensioning device comprises one or more turns. The handle portions may include ring-shaped distal ends that further enhance grip. The jaw portions may be shaped, curved, bent or otherwise configured to provide access to specific areas of a procedure. The clamp may be coated with a material providing improved traction and padding. In a method of the invention, a single wire is wound at least one turn forming the central coil and two extensions. A first extension of the wire is formed into the first jaw portion by bending back on itself, the first extension is then returned to the central coil where it is formed to rest upon an outer surface of the central coil. The bent first extension, which now extends rearward in a direction opposite to the direction of the first jaw portion, is then bent again forming the first handle portion. A second extension is similarly bent to form the second jaw portion and the second handle portion. The single-wire construction of the clamp may be achieved through programmed wire forming. In another aspect of the invention, a plurality of clamps may be placed upon a traction rod made from a metal or plastic material to align two or more stump portions of a severed vessel or tissue for reconnection or anastomosis.

    摘要: The invention relates to a surgical instrument for at least partially occluding a body conduit comprising a first jaw, a second jaw opposing the first jaw and moveable relative to the first jaw to occlude the conduit, and an insert being mounted by at least one of the first and second jaws with a length of the insert extending along at least one of the first and second jaws. One of the first and second jaws may further comprise a retention barb to provide a friction fit with the insert. The insert is flexible, disposable and may be formed by injection molding. The retention barb may be a three-sided or multiple-sided barb that is formed at the proximal end of at least one of the first and second jaws. The first and/or second jaws may be bent and/or curved. In another aspect, the insert comprises an outer wall and an inner wall for fitting over the jaw, and the inner wall further comprises a molded, rectangular raised ring formed at the proximal end to aid the retention of the insert over the retention barb of the jaw. The insert may be removed from the jaw by pulling the insert in a distal direction to overcome the friction fit of the retention barb. The insert may further include a soft tip covering the distal end of one of the jaws to minimize trauma during surgery. The distal ends of the jaw and the insert may be tapered to allow ease of installation and removal. In another aspect, the insert and jaws may be removably attached to one another in a snap-fit relationship where the jaws may include one or more holes and the insert may include one or more projections. It is appreciated that the holes and projections may vary in width, depth and height depending on application.
