Abstract
A hemostatic forceps (20) includes a pair of forceps elements (forceps cups (1)) constituted of a conductive metal and configured to serve as high-frequency electrodes and configured to be able to change into a state where front portions of the pair of forceps cups (1) are open, and a state where the pair of forceps cups (1) are close. A sawtooth portion (15) having a plurality of concavo-convex structures which constitute a sawtooth-shape is provided on at least one of respective closing-side surfaces (17) of the pair of forceps cups (1). The sawtooth portion (15) is provided with an electrically insulative coating over its bottom portion (21), but not on a top portion (22) thereof, and hence the top portion (22) is conductive.
