| 20080200940 | ULTRASONIC DEVICE FOR CUTTING AND COAGULATING - An ultrasonic surgical instrument that is configured to permit selective positioning of the relative distance between an end effector for cutting and coagulating tissue and a power actuation switch that is carried by the instrument for selectively energizing the end effector. In one instance, the end effector is able to change position relative to the actuation switch, alternatively, the actuation switch moves relative to the end effector, and still further, both the end effector and the actuation switch are capable of moving relative to each other. | 08-21-2008 |
| 20080234708 | Surgical instruments - 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. | 09-25-2008 |
| 20080234710 | Ultrasonic surgical instruments - A surgical instrument includes a transducer configured to produce vibrations at a predetermined frequency. The transducer is configured to produce vibrations along a longitudinal axis at a predetermined frequency. An ultrasonic blade extends along the longitudinal axis and is coupled to the transducer. The ultrasonic blade includes a body having a proximal end and a distal end. The distal end is movable relative to the longitudinal axis by the vibrations produced by the transducer. The body includes a treatment region that extends from the proximal end to the distal end. The body includes a substantially flat broad top surface, a bottom surface, and a neck portion protruding from the proximal end adapted to couple to the transducer. | 09-25-2008 |
| 20080284114 | Motor-driven laparoscopic seal assembly - A motor driven seal assembly for permitting hand assisted laparoscopic procedures. The seal assembly includes a seal cap having a seal positioned within a housing, the housing includes a lower seal ring having a track which supports an upper seal ring for rotational motion relative thereto. The seal is supported between the upper seal ring and the lower seal ring for rotation between an open orientation and a closed orientation. A motor-driven drive assembly is associated with the lower seal ring and the upper seal ring for controlling relative to movement thereof | 11-20-2008 |
| 20090030437 | Surgical instruments - A surgical device. The surgical device may comprise a transducer configured to provide vibrations along a longitudinal axis and an end effector coupled to the transducer and extending from the transducer along the longitudinal axis. The surgical device also may comprise a lower jaw extending parallel to the end effector. The lower jaw may comprise a clamp face extending toward the longitudinal axis. Also, the lower jaw may be slidable relative to the end effector to bring the clamp face toward a distal end of the end effector. | 01-29-2009 |
| 20090105750 | ERGONOMIC SURGICAL INSTRUMENTS - A surgical instrument handle assembly includes a housing having a proximal end and a distal end. A proximal opening is formed at the proximal end of the housing. A distal opening is formed at the distal end of the housing. The proximal and the distal openings define a longitudinal axis. A handle extends downwardly from the longitudinal axis. The handle defines a proximal contact surface, a saddle surface, and a stabilization tail. A trigger is pivotally attached to the housing and is pivotally moveable relative to the handle. | 04-23-2009 |
| 20100069940 | Ultrasonic Device for Fingertip Control - An ultrasonic surgical instrument comprises a handpiece and an ultrasonically actuated blade distal to the handpiece. The instrument includes an activation member that is operable to selectively activate the blade and a controller that is operable to select the energy level at which the blade will be activated. The activation member may comprise capacitive switches; resistive sensors; resonant cavity switching technology; infrared sensing technology; technology that uses a resonant, standing wave on a surface that is perturbed by the presence of a finger; and/or any other suitable type of technology. The controller may comprise the same. The controller may permit selection from three or more available ultrasonic energy levels. The activation member and/or controller may be manipulated from various longitudinal positions on the handpiece and/or various rotational positions about the handpiece, such that the handpiece may be gripped in a variety of ways. | 03-18-2010 |
| 20110015631 | ELECTROSURGERY GENERATOR FOR ULTRASONIC SURGICAL INSTRUMENTS - 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. | 01-20-2011 |
| 20110015660 | ROTATING TRANSDUCER MOUNT FOR ULTRASONIC SURGICAL INSTRUMENTS - In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that comprises a handpiece housing that operably supports an electrical contact assembly therein that is in electrical communication with a signal source. An acoustic assembly is supported within the handpiece housing in rotatable contact with the electrical contact assembly. In various embodiments, the signal source produces at least one of an ultrasonic signal and a radio frequency signal. | 01-20-2011 |
| 20110082486 | DEVICES AND TECHNIQUES FOR CUTTING AND COAGULATING TISSUE - Various embodiments are directed to an apparatus and method of driving an end effector coupled to an ultrasonic drive system of a surgical instrument.
