Abstract
An electrocautery probe includes a single probe arm and an electrode. The electrode includes one end attached to the probe arm and a free end. According to one embodiment of the invention, the electrode is a wedge, preferably having a substantially triangular cross section. According to another embodiment of the invention, the free end of the electrode rises higher than the attached end of the electrode. The free end of the electrode may be planar, pointed, or rounded. Where the free end of the electrode is planar, it may be inclined in either the proximal or distal direction. According to yet another embodiment of the invention, the electrode is a roller barrel. The electrocautery probe has several advantages over two armed electrocautery probes. First, the electrocautery probe has only one arm obscuring the physician's view through the lens of the resectoscope. Second, the free end of the electrode can be used for sculpting tissue and for resecting tissue in narrow areas. Third, the free end of the electrode can be used for spot coagulation. Fourth, the free end is capable of larger resections than possible with a two-armed electrocautery probe. In addition, the electrocautery probe fits into a standard resectoscope without modification to the resectoscope device.
