Abstract
An electrosurgical hemostatic instrument is provided in which the coagulation status of tissue engaged by two elements delivering an electrosurgical energy to tissue may be observed, and in which damage from thermal spread may be minimized. A preferred embodiment of the invention provides a bipolar endoscopic clamping, coagulation and cutting device. The coagulation may be observed by exposed electrode tips at the distal end of the instrument, an open knife slot which permits the escape of vapor, plume, steam or smoke from the coagulation process, windows located in the first or second element through which coagulating tissue may be observed, indentation in one of the elements which exposes a tissue contacting surface of the other element; a temperature indication strip located on the distal end of the instrument, or a current indicator located on the instrument.
