ABSTRACT:
An electrosurgical probe is provided which reduces the likelihood of arcing from the probe. In addition, the probe provides the ability to place a fiber-optic cable through the probe for providing for laser surgery or for laproscopic examination of the patient. The electrosurgical probe comprises an electrosurgical tip, a cylindrical body attached to the tip, and a base attached to the cylindrical body. The tip may have many different shapes but a spatula shape is generally preferred. The tip has at least one notch in the periphery of the spatula shape for retaining a fiber-optic cable. The cylindrical body is substantially hollow so that suction, irrigation, and laparoscopy may be carried out through the probe. To aid the surgeon in determining dimensions of organs within a patient, the cylindrical body has a plurality of striped regions having a predetermined thickness spaced apart at predetermined intervals on an outer surface of the cylindrical body. The cylindrical body is composed of an insulative material for preventing accidental shock to a patient. To prevent accidental arcing, an insulative layer which substantially covers the electrosurgical tip with at most a 4 mm extension of the electrosurgical tip exposed with no insulative layer.
