| 摘要 |
The invention relates to an electrosurgical instrument, comprising instrument arms (4, 6) that can be moved relative to each other, each having one or more electrode surfaces (20-1, 20-2, 20-3, 20-4) between which a tissue can be clamped and electrothermally treated. The movement of the instrument arms (4, 6) relative to each other can be limited by at least two spacers (22, 23, 24), which are arranged at a distance from one another in the longitudinal extension of the instrument arms (4, 6) and act on the instrument arms (4, 6). At least one electrode surface section loaded in bending in a closed position of the instrument arms (4, 6) is arcuate, in particular concave, oppositely the expected bending direction and in the longitudinal direction. |
