Abstract: A suction device with an irrigation function exhibits reduced occurrence of jamming and can be easily manipulated. A flexible tube 21 is removably connected to a flexible tube connection 22 of a suction device body 20. A suction path 25 is substantially straightly aligned with the flexible tube connection 22. An irrigation path 27 is formed as a branch path of the suction path 25. When a rotation lever 31 is not pressed, the suction path 25 communicates with the flexible tube 21. As the lever 31 is pressed, the communication is disconnected and the irrigation path 27 begins to communicate with the flexible tube 21 through a zero point state.

Abstract: A blood vessel coagulation/stanching device for flowing high-frequency current between a pair of forceps with a blood vessel being held between the ends of the forceps to cauterize, coagulate and stanch the blood vessel, the device being characterized in that the blood vessel holding section of the forceps comprises a blood vessel contact member made of an electrically insulating sintered substance with a low thermal conductivity, and the blood vessel contact member being provided on its surface with exposed electrodes at an areal ratio between 5% and 60% to the entire surface of the blood vessel contact member. With this device, the blood vessel contact section of the forceps is not excessively heated, preventing a blood vessel from burning. This eliminates any stanching failure due to removal of a coagulated blood vessel portion and ensures superior coagulation and stanching.
