摘要： The present invention relates to a surgical stapler comprising: a support base; a trigger; a handle; a retaining pin operatively connected to and extending distally from a support base, the support base being operable in the surgical stapler to cause the stapler to position staples near tissue; and a unit lockout rotatable about a pivot fixed to the handle. The unit lockout comprises an upper end near and under at least one blocking plate in the stapler; and another end facing the trigger to prevent it from firing when the upper end is blocked from upward movement by the at least one blocking plate. Whereas the upper end of the unit lockout is moved relative to the at least one blocking plate so that the upper end of unit lockout is no longer under the at least one blocking plate to permit the unit lockout to rotate about the pivot.

摘要： An abrasive tool insert is formed from a substrate having an inner face that has a center, and annular face which annular face has a periphery. The inner face slopes outwardly and downwardly from the center at an angle ranging from between about 5° and 30° from the horizontal. The annular face surrounds by the inner face and terminates at the periphery. The annular face slopes downwardly and outwardly from the inner face at an angle of between about 20° and 75° from the horizontal. A continuous abrasive layer, having a center and a periphery forming a cutting edge, is integrally formed on the substrate and defines an interface therebetween.

摘要： In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. In another general aspect, the surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw.
