At an endoscopic polypectomy, bipolar snare compared with monoporal snare does not need an opposite-poles board, but has an advantage without the obstacle at the time of the current. Bipolar snare (B-Wave) made from ZEMEX developed newly makes a snare wire and a snare sheath as poles, and is carrying out characteristic form which coagulates the constricted material by the heat effect in the meantime. Since we performed the trial that this B-Wave is used for mucosal incision as a cutting knife, we reported. The advantage of a grade, which does not need an opposite-poles board from the former compared with a certain needlelike scalpel, by which the bleeding at the time of the incision is mitigated and by which incision depth tends to control, is mentioned. Moreover, two functions of a snare and a cutting knife can be demonstrated with one instrument, and it is thought that the instrument may be further used widely by future improvement.
