    摘要: An ultrasonic-surgical-shears tissue pad has a tissue-pad body including a base material and at least one filler material. An alternate ultrasonic-surgical-shears tissue pad has a tissue-pad body having adjoining first and second regions, wherein the first region includes a first material and wherein the second region includes a second material. An ultrasonic surgical shears includes an ultrasonic surgical blade and a clamping arm which is operable to open and close toward the blade and which has a transversely and resiliently flexible distal tip. An alternate ultrasonic surgical shears includes an ultrasonic surgical blade, a clamping arm operable to open and close toward the blade, and a tissue pad attached to the clamping arm and having a clamping surface, wherein at least a portion of the tissue pad is resiliently flexible in a direction substantially perpendicular to the clamping surface.

    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 force limiting 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.
