  • Patent number: 9801648
    Abstract: A surgical instrument that may include a housing, a transducer engaged with the housing which can produce vibrations, and an end-effector engaged with the transducer. The surgical instrument can further include an adjustable sheath extending from the housing where the sheath is movable relative to the distal tip of the end-effector and where the distance between the distal tip of the sheath and the distal tip of the end-effector can be set such that the sheath can act as a depth stop. The sheath can be adjusted such that, when the distal tip of the sheath contacts the tissue or bone being incised, the surgeon can determine that the appropriate depth of the incision has been reached. In other embodiments, the end-effector can be moved with respect to the sheath in order to adjust the distance between the distal tip of the end-effector and the distal tip of the sheath.

  • Patent number: 9700343
    Abstract: Various forms are directed to systems and methods for driving an end effector coupled to an ultrasonic drive system of a surgical instrument. A generator may generate at least one electrical signal. The at least one electrical signal may be monitored against a first set of logic conditions. When an ultrasonic impedance of the surgical instrument exceeds a threshold impedance, a resonant frequency of the at least one electrical signal may be stored as a baseline frequency. A first response of the generator may be triggered upon the occurrence of either the first set of logic conditions being met or the resonant frequency of the at least one electrical signal differing from the baseline frequency by a baseline deviation threshold.

    Abstract: The illustrative embodiments described herein are directed to apparatuses, systems, and methods for managing liquid flow associated with a tissue site that involves using reduced pressure to control fluid flow. In one instance, an apparatus includes a first valve and a second valve in fluid communication with a reduced-pressure source. The valves are movable between an open position and a closed position and are operable to change flow status (open to closed or vice versa) based on a presence of reduced pressure. At least one of the first valve or the second valve is in the closed position to obstruct a flow of a liquid while the other is in the open position. The apparatus also includes a reservoir fluidly coupled to the first valve and the second valve. Other systems, methods, and apparatuses are presented.
