    摘要: A surgical instrument can comprise a handle, a first conductor, a second conductor, and an end effector. The end effector can comprise a first jaw, a second jaw, wherein the first jaw is movable relative to the second jaw in order to capture tissue intermediate the first jaw and the second jaw, a first electrode electrically coupled with the first conductor, and a second electrode electrically coupled with the second conductor, wherein the second electrode is comprised of a material configured to have a first electrical resistance when a first pressure is applied to the material, and wherein the material is configured to have a second electrical resistance when a second pressure is applied to the material. In various circumstances, the material can be configured such that, once the applied pressure has exceeded a switching pressure, the resistance of the material can switch from the first resistance to the second resistance.

    摘要: A tissue retrieval device includes an introducer tube and a tissue retrieval bag. The introducer tube is sized to be inserted into a patient through a trocar. The tissue retrieval bag may be selectively exposed at the distal end of the introducer tube within the patient. The tissue retrieval bag may receive a tissue specimen and be withdrawn from the patient. The tissue retrieval bag may include an inflatable portion. When inflated, the inflatable portion may extend the tissue retrieval bag from a contracted configuration to an expanded configuration. The inflatable portion may substantially seal a tissue specimen within the tissue retrieval bag. The tissue retrieval bag may me formed of an environmentally sensitive material such that the size of the tissue retrieval bag expands when the tissue retrieval bag is exposed within the patient.

    摘要: A specimen retrieval instrument comprises a tubular member, a resilient member, and a retrieval bag. The resilient member is associated with a distal end of the tubular member. The bag is secured to the resilient member. The resilient member is compressible such that the resilient member and bag fit within a hollow interior portion of the tubular member. A rod may advance the resilient member and bag out of the tubular member. Alternatively, the tubular member may comprise a sheath that is retractable to reveal the resilient member and bag. The resilient member may have a hoop, spiral, or rolled strip configuration. The resilient member may alternatively comprise telescoping arms. The resilient member opens the bag when the resilient member and bag are deployed relative to the tubular member. The resilient member may also unfurl the bag when the resilient member and bag are deployed.
