    摘要: In various embodiments, a surgical instrument for operation in an aqueous environment is provided. In at least one embodiment, the surgical instrument may include a hollow sheath, a blade disposed at least partially within the hollow sheath and extending through an opening in the sheath, and at least one ultrasonic transducer operably coupled to the blade. The blade may include a polygonal cross-sectional shape and the tip may project away from the sheath's longitudinal axis. In another embodiment, the surgical instrument may include a blade with suction disposed therethrough and at least one ultrasonic transducer operably coupled to the blade. The blade may include a cutting edge that is positioned over a blade opening. Also, the cutting edge may project away from the blade's longitudinal axis.

    摘要: A surgical instrument can comprise an end effector including a plurality of jaws which can be configured to compress tissue therebetween. The end effector can further comprise one or more electrodes which can be configured to direct a flow of electrical current through the tissue in order to heat the tissue and denature collagen and/or other proteins within the tissue. As the tissue cools, the collagen and/or other proteins can renature and thereby seal the tissue. In certain embodiments, the end effector of the surgical instrument can further comprise movable portions which can apply a tension force to the tissue surrounding the tissue being sealed. In various circumstances, the tension force can reduce the over-denaturation, shrinkage, and/or other damage to the surrounding tissue caused by heat flowing from the end effector during the sealing process.

    摘要: A tissue processing system includes a tray and a processing component. The processing component has teeth configured to dice, mince, and mix the tissue in the tray. In some versions, teeth of a rotary member mesh with teeth of a stationary member, such that the tissue is ground between the meshing teeth. The rotary member may be moved in an orbital path relative to the stationary member. In some versions, the teeth of two rotary members mesh together, and the rotary members are rotated in opposite directions to grind the tissue. The rotary members may also be alternatingly moved up and down to perform initial dicing on the tissue. Once the tissue has been processed, the tissue may then be used in a therapeutic manner, such as by being incorporated with a scaffold and then implanted in the same patient from whom the tissue was originally harvested.
