摘要：
An ultrasonic clamp coagulator assembly (100) that is configured to permitselective cutting, coagulation and clamping of tissue during surgicalprocedures. An elongated portion of the instrument can be configured forendoscopic applications and has an outside diameter of less than 6mm. Theconstruction includes a clamping mechanism, including a clamp arm pivotallymounted at the distal portion of the instrument, which is specificallyconfigured to create a desired level of tissue clamping forces, exceeding 4pounds when the trigger is fully closed. The clamping mechanism includes a two-piece pad design and pad material that enables the higher tissue clampingforces and a force-limiting mechanism that effectively smooths out abusivetissue forces. The assembly also features hand activation configured toprovide an ergonomical grip and operation for the surgeon. Hand switches areplaced in the range of the natural swing of the surgeon's thumb, whethergripping the surgical instrument right-handed or left handed.
