摘要： An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation and clamping of tissue during surgical procedures. An elongated portion of the instrument can be configured for endoscopic applications and has an outside diameter of less than 6mm. The construction includes a clamping mechanism, including a clamp arm pivotally mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces, exceeding 4 pounds when the trigger is fully closed. The clamping mechanism includes a two-piece pad design and pad material that enables the higher tissue clamping forces and a forcelimiting mechanism that effectively smooths out abusive tissue forces. The assembly also features hand activation configured to provide an ergonomical grip and operation for the surgeon. Hand switches are placed in the range of the natural swing of the surgeon's thumb, whether gripping the surgical instrument right-handed or left handed.

摘要： An ultrasonic instrument (10) comprises a body (22), a shaft assembly, an ultrasonic blade (42), and a pivoting member (50). The shaft assembly extends distally from the body. The ultrasonic blade is positioned distal to the shaft assembly. The pivoting member is pivotable with respect to the blade from an open position to a closed position to thereby clamp tissue between the pivoting member and the blade. One or both of the shaft assembly or the pivoting member comprise a guide feature (100, 110, 120, 130, 140, 600). The guide feature is configured to provide lateral alignment of the distal portion of the pivoting member with the blade as the pivoting member is pivoted to the closed position.

摘要： A bipolar electrosurgical instrument having a pair of relatively moveable jaws (22, 24) , each of which includes a tissue contacting surface. The tissue contacting surfaces of the jaws are in face-to-face relation with one another, and adjacent each of the tissue contacting surfaces are first and second spaced-apart electrodes (42, 44, 46, 48) that are adapted for connection to the opposite terminals of a bipolar RF generator. The first and second electrodes of one jaw are in offset opposed relation with the first and second electrodes of the second jaw. A cutting portion is provided between the jaws. The cutting portion (36) is moveable to provide the instrument with a scissors grasper capability. A tissue dam (656) is included on at least one jaw to help contain tissue within the desired coagulation area, and thereby help contain current density between the electrodes.

摘要： Various embodiments described herein are directed to ultrasonic blades. For example, an ultrasonic blade may comprise a proximally positioned straight section extending along a longitudinal axis and a distally positioned curved section coupled to the straight section and curved away from the longitudinal axis. The curved section may define a radius of curvature and subtend a first angle. A point of tangency between the curved section and the straight section may be positioned at either a node of the ultrasonic blade or an anti-node of the ultrasonic blade.

摘要： A bipolar electrosurgical instrument having a pair of relatively moveable jaws, each of which includes a tissue contacting surface. The tissue contacting surfaces of the jaws are in face-to-face relation with one another, and adjacent each of the tissue contacting surfaces are first and second spaced-apart electrodes that are adapted for connection to the opposite terminals of a bipolar RF generator so as to generator a current flow therebetween. The first and second electrodes of one jaw are in offset opposed relation, respectively, with the first and second electrodes of the other jaw. The tissue contacting surfaces are disposed between the electrodes on each jaw, and the first opposed electrodes of each jaw are connectable to one terminal of the bipolar RF generator, while the second opposed electrodes of each jaw are connectable to the other terminal of the bipolar RF generator. A cutting portion is provided between the jaws. The cutting portion is moveable to provide the instrument with a scissors-like capability or a grasper-like capability, depending on the position of the cutting portion.
